Lost Asian satellites send powerful signals
By Peter J Brown

During the second half of 2010 all three Asian space powers - China, India and Japan - suffered major satellite failures. Each failure is significant, but for different reasons. In this instance, the satellite failures will be addressed in chronological order.

At the same time, it must be emphasized that satellite failures happen rarely.

What makes the loss of India's Insat-4B in early July - the first Asian satellite on this list - so important is the possibility that the satellite fell victim to deliberate act of sabotage as the result of a cyber attack. This involves the very malicious "Stuxnet" worm.

The official line is that a power supply
problem stemming from a faulty solar panel was the culprit.

Others wonder if while everyone was speculating about the impact of a Stuxnet-based cyber attack on an Iranian nuclear facility, an Indian satellite was rendered useless by the same sinister software code. At least, that is the theory.

Security technologist and author Bruce Schneier described Stuxnet in the following way.

"Stuxnet is an Internet worm that infects Windows computers. It primarily spreads via USB sticks
, which allows it to get into computers and networks not normally connected to the Internet. Once inside a network, it uses a variety of mechanisms to propagate to other machines within that network and gain privilege once it has infected those machines," said Schneier. [1]

If it turns out that Insat-4B met its demise because someone hacked the satellite's control system software or hacked software inside an Indian ground control station in a two-step attack, this is a very sobering moment for the global satellite industry.

Stuxnet began to surface at around the exact same time that Insat-4B went on the blink. By the way. Stuxnet is known to target industrial control systems.

The Indian Space Research Organization (ISRO) had already lost one communications satellite earlier in 2010. In April, ISRO lost the GSAT-4 communications satellite after ISRO's GSLV-D3 rocket malfunctioned. An earlier GSLV series rocket failure took place in 2006, destroying the INSAT-4C satellite. So, the loss of Insat-4B which was launched in early 2007 put satellite TV service providers along with other users in India in a very difficult spot.

In late September, cyberwarfare expert and author Jeffrey Carr, who is a Forbes magazine contributor and the CEO of Taia Global, wrote on the Forbes "Firewall" blog that the loss of Insat-4B can be traced to specific purchases made by ISRO which unbeknownst to ISRO set the silent and destructive effects of Stuxnet in motion.

"According to the resumes of two former engineers who worked at the ISRO's Liquid Propulsion Systems Center, the Siemens software in use is Siemens S7-400 PLC and SIMATIC WinCC, both of which will activate the Stuxnet worm," said Carr. "I uncovered this information as part of my background research for a paper that I am presenting at the Black Hat Abu Dhabi [computer security] conference in November. My objective for that presentation will be to provide an analytic model for determining attribution in cases like Stuxnet. My objective for this post is simply to show that there are more and better theories to explain Stuxnet's motivation than just Israel and Iran, as others have posited." [2]

Carr also described how so many customers who relied on Insat-4B ended up on the ASIASAT-5 satellite , and that, "AsiaSat's two primary shareholders are General Electric and China International Trust and Investment Co. (CITIC)," which is a Chinese state-owned company.

As the size and scope of the Stuxnet phenomenon becomes more widely understood, experts are stunned by the growing presence in India where "infections" were rampant in late September. [3]

Two weeks after the Insat-4B failure, ISRO activated Cartosat-2B - its latest remote sensing satellite - which offers high-resolution imagery via a panchromatic camera. It has functioned flawlessly thus far as it orbits approximately 630 kilometers above the earth. This demonstrates that ISRO was launching and operating other new satellites without any problems during the same time period.

Satellite communications and satellite surveillance are two different thing entirely. Spy satellites are increasing in number over Asia, and they are much more powerful than their predecessors.

In late August, the Japanese government reported that it lost its only operational synthetic aperture radar (SAR)-equipped surveillance satellite. Japan still maintains a fleet of three optical spy satellites. So, in bad weather or when night comes, Japan cannot conduct its own satellite surveillance operations.

Here again a power supply failure was the primary contributor to the satellite malfunction in question. Was there a Stuxnet connection? Thus far, malevolent software or a worm has not been mentioned as a potential source of the problem. But in late 2010, it cannot be ruled out entirely.

A significant window has now closed in Japan and while a replacement satellite may appear late next year in the form of a new prototype or test platform, a full compliment of surveillance satellites is not expected until well after 2013 at the earliest. The latest launch of a Japanese spy satellite was in November 2009. [4]

When Japan lost its first SAR satellite in 2007, also to a power failure, it briefly triggered a wave of domestic soul-searching in the highest circles of the Japanese government. Now, more than 3 years later, Japan's dependence on the US - absent a suitable alternative partner which, of course, could well be India. - and upon imagery generated by US commercial earth observation satellites in particular is not a controversial subject.

As 2010 comes to an end, however, anxiety is bound to intensify in Tokyo and disputes in the Diet [parliament] may erupt thanks to a new report from the Washington, DC-based Institute for Science and International Security which includes satellite imagery of a North Korean nuclear site. DigitalGlobe, a US-based satellite operator, is the source of the imagery. [5]

This satellite imagery and the circumstances in which the Japanese now find themselves due to the loss of Japan's only radar satellite - and the absence of any redundancy - coincides with questionable activity at this North Korean nuclear site. Add it all up and it could prove to be a very disruptive situation for the Japanese government.

On the other hand, this makes the announcement by the Japanese Ministry of Defense concerning the possible acquisition of three unmanned US Global Hawk reconnaissance aircraft perhaps easier to digest by the Japanese people as a whole.

These Global Hawk robotic spy planes will greatly enhance Japan's ability to conduct surveillance operations over land and sea. They will also enable Japan to develop its own innovative satellite-based surveillance architectures, while providing a means to watch North Korea closely.

While this Global Hawk procurement may also bring about a resurgence of support for another Japanese attempt to obtain advanced US F-22 fighter aircraft - "Why do they give us Global Hawks, but not F-22's?" - it may alter the process that guides Japan's creation and deployment of intelligence-gathering satellites and bring about a larger, more flexible and more diverse satellite fleet. [6]

In China, the loss of another satellite is also impacting what is seen - on people's TV sets.

In early September, Chinasat-6A also known as Zhongxing 6A, ZX 6A, Sinosat-6, or Xinnuo 6 suffered a helium pressurization problem immediately after launch. This affected the operation and control of the satellite's onboard fuel tank. For its owner, China Satellite Communications Corp of Beijing, it means that uncertainty about the operational status and projected life span of this new satellite is going to linger for some time.

So, although China did not "lose" a satellite here in a technical sense, the setback is severe enough to warrant its consideration here for several reasons.

Chinasat-6A is one of the Chinese-built DFH-4 series. These satellites have experienced complete failures in the past. Indeed, the record of success for the DFH-4 to date is remarkably slim. Chinasat-6A unlike Sinosat 2 and Nigeria's Nigcomsat-1 - earlier DFH-4 failures - is not crippled by a solar array - related problem. [7]

The questionable status of this satellite not only affects its users, but also China's satellite exports. The DFH-4 has been China's preferred export satellite, and the malfunction does not bode well for business overseas at a time when China is aggressively seeking satellite partners abroad.

Back at home, planning and policy-making across the complete satellite TV and TV infrastructure of China as a whole could be affected by this satellite glitch. Among other things, it could become a factor in China's efforts to curb illegal satellite TV.

For months, China has discussed possibly ceasing crackdowns in the future on the owners of unauthorized or illegal satellite dishes which some say now number 60 million or more. China Satellite Communications (China Satcom) has played a role in this process. China's only authorized domestic satellite TV service for households, China Satcom began offering many free satellite TV channels last year.

"Since our service launched, most of the illegal DTH viewers have turned their dishes away from foreign satellites and onto our domestic platform," said Huang Baozhong, vice president of China Satcom. "This helps the Chinese government with propaganda control."

The loss of Chinasat-6A may be inconsequential or it could adversely impact the supply domestic satellite capacity to the point that it provides opponents of reform with the excuse to postpone or delay the imposition of new rules and regulations.

And whereas provincial broadcasters might have been able to bypass links to either Beijing and Shanghai as part of their broadcast operations, here again, reduced satellite capacity might cast a shadow over this proposed transition. [8]

At the same time, discussions about censorship and propaganda control in China involving foreign media and satellite TV channels available heated up considerably in early October following Premier Wen Jiabao's latest interview with CNN's Fareed Zakaria.

Because Wen seems eager to champion political reform in China - some openly question his sincerity - and speaks of "the continuous progress of China," the fact that millions of Chinese satellite TV viewers had no opportunity to view the interview in question can only set the stage for storminess in the form of a clash of opposing viewpoints. [9]

Who will prevail remains to be seen, but the absence or a significant shortage of satellite capacity - even when artificially inflated - is a barrier unto itself and might serve the purposes of those who wish not to open the door entirely in China today. Thus, Chinasat-6A could emerge as a useful prop on the stage of domestic politics.

Finally, there has been widespread speculation about a very controversial Chinese satellite loss last January. Last summer, China was accused of shooting down one of its satellites in January, a repeat of its 2007 satellite shootdown although this time without all the fanfare.

"It was a large test which needs time to prepare for," said Peng Guangqian, a Beijing-based military expert. "If confirmed, I think it was a further step for China to improve its defensive ability in space." [10]

The fate of that satellite is something that Beijing refuses to verify despite the fact that there is no real element of secrecy involved.

The vast majority of satellites perform solidly, round-the-clock in a reliable fashion that is a source of pride for their builders. Thus, these lost Asian satellites represent the exception not the rule. Still, whether viewed as the victims of isolated mishaps or not, these errant satellites still send out powerful signals.

Hubble telescope uncovers an overheated early universe



WASHINGTON (BNS): A team of astronomers recently discovered that quasars emitted massive blasts of radiation in the early Universe, essentially delaying the growth of dwarf galaxies by as much as 500 million years.

The team used the new capabilities of NASA's Hubble Space Telescope to probe the invisible, remote universe.

With the help of newly installed Cosmic Origins Spectrograph (COS) they have identified an era, from 11.7 to 11.3 billion years ago, when the universe stripped electrons off from primeval helium atoms -- a process called ionization.


This diagram traces the evolution of the universe from the big bang to the present. Two watershed epochs are shown. Not long after the big bang, light from the first stars burned off a fog of cold hydrogen in a process called reionization. At a later epoch quasars, the black-hole-powered cores of active galaxies, pumped out enough ultraviolet light to reionize the primordial helium. Credit: NASA, ESA, and A. Feild (STScI). For a larger version of this image please go here.

This process heated intergalactic gas and inhibited it from gravitationally collapsing to form new generations of stars in some small galaxies. The lowest-mass galaxies were not even able to hold onto their gas, and it escaped back into intergalactic space.

Michael Shull of the University of Colorado and his team were able to find the telltale helium spectral absorption lines in the ultraviolet light from a quasar, according to a NASA news release.

Quasar is a very energetic and distant galaxy with an active galactic nucleus. They are the most luminous objects in the universe. Quasars were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light, which were point-like, similar to stars, rather than extended sources similar to galaxies.

The universe went through an initial heat wave over 13 billion years ago when energy from early massive stars ionized cold interstellar hydrogen from the big bang. This epoch is actually called reionization because the hydrogen nuclei were originally in an ionized state shortly after the big bang.

The astronomers determined that it would take another two billion years before the universe produces sources of ultraviolet radiation with enough energy to reionize the primordial helium that was cooked up in the big bang. Such radiation came from supermassive black holes.

The helium's reionization occurred at a transitional time in the universe's history when galaxies collided to ignite quasars. After the helium was reionized, intergalactic gas again cooled down and dwarf galaxies could resume normal assembly.

At present, Shull and his team only have one perspective to measure the helium transition to its ionized state. However, the COS science team plans to use Hubble to look in other directions to determine if helium reionization uniformly took place across the universe.

Russian rocket blasts off carrying three astronauts to ISS




Baikonur, Kazakhstan (AFP) Oct 8, 2010
A Russian Soyuz rocket carrying three astronauts to the International Space Station blasted off Friday from Russia's Baikonur cosmodrome in Kazakhstan.

The rocket took off into the night sky on schedule at 3:11 am Moscow time (23:11 GMT Thursday), creating a spectacular yellow light. Russian space officials said the launch had gone according to plan.

Their Soyuz TMA-M spacecraft is a modernised version of the ship used by Russia to put humans into the space. It is the first such craft to be fully equipped with a digital measuring system and Friday's launch was the first time the new design has been used.

The spacecraft is due to dock with the International Space Station (ISS) at 4:02 am Moscow time (0:02 GMT) on Sunday.

The crew includes one of Russia's most experience spacemen, Alexander Kaleri, whose first mission to space was in in March 1992 just after the fall of the Soviet Union to the now defunct Russian space station Mir.

Kaleri has already made four space flights, logging up 610 days in space and almost 24 hours of spacewalks, his last trip an October 2003 mission to the International Space Station.



Joining him are American Scott Kelly, who has made two spaceflights and Oleg Skripochka, who is making his first space flight.

ISS Crew Hard At Work As New Crew Members Prepare For Launch
Houston TX (SPX) Oct 07, 2010 - The Expedition 25 crew has been working on the International Space Station's treadmill located inside the Russian segment. The treadmill is disassembled, inspected then reassembled as part of its six-month maintenance schedule.

Photographs are taken of the exercise device's parts and downlinked to Earth for analysis by specialists.

Commander Doug Wheelock continues working on the Oxygen Generation System in the Destiny laboratory. Wheelock is installing a system that will combine carbon dioxide and hydrogen to create water and methane.

The water will be used in the station's Water Processing Assembly and the methane will be vented overboard.

Flight Engineer Fyodor Yurchikhin continued his work in the Russian segment of the International Space Station. Yurchkihin updated the Inventory Management System and replaced equipment in the Zarya control module. He also inspected filters and checked coolant levels.

The Soyuz TMA-01M spacecraft is at the launch pad in Kazakhstan and set for a Thursday launch at 7:10 p.m. EDT to carry three new Expedition 25 crew members to the International Space Station.

Flight Engineers Scott Kelly, Alexander Kaleri and Oleg Skripochka are due to arrive at the orbiting laboratory Saturday and dock to the Poisk module at 8:02 p.m.

Soyuz Moved To Pad For Thursday Launch To Station
Baikonur, Kazakhstan (SPX) Oct 06, 2010 - The Soyuz spacecraft that will carry three new Expedition 25 flight engineers to the International Space Station was rolled out to the launch pad at the Baikonur Cosmodrome in Kazakhstan on Tuesday.

NASA astronaut Scott Kelly and Russian cosmonauts Alexander Kaleri and Oleg Skripochka will launch aboard the new Soyuz TMA-01M Thursday at 7:10 p.m. EDT (Friday, Kazakhstan time) and begin a five-month tour of duty aboard the station after docking to the Poisk module Saturday evening.

Meanwhile, the three Expedition 25 crew members already living and working aboard the station conducted a depressurization drill, collected data for science research and prepared for the installation of a device to produce water.

Commander Doug Wheelock began his workday early by participating in the Pro K experiment, which studies dietary countermeasures to lessen the bone loss experienced by astronauts during long-duration spaceflight.

With assistance from Flight Engineer Shannon Walker, Wheelock collected a blood sample and stored it in the Minus Eighty-Degree Laboratory Freezer for ISS for study later by scientists back on Earth.

Walker spent much of her morning with the Capillary Flow Experiment for an investigation of capillary flows and flows of fluids in containers with complex geometries.

Results of this study will improve current computer models used by designers of low-gravity fluid systems and may improve fluid transfer systems on future spacecraft.

Flight Engineer Fyodor Yurchikhin continued unpacking cargo from the ISS Progress 39 spacecraft that has been docked to the aft port of the Zvezda service module since September

Later Yurchikhin joined Wheelock and Walker for an emergency drill to sharpen the crew's response to a rapid, unexpected loss of cabin pressure within the station. Afterward the three tagged up with flight controllers for a debrief of the drill.

After a break for lunch, Wheelock used a ham radio to speak with students at the Institute of Research and Education in Italy and answered a variety of questions about life aboard the space station.

Wheelock then tagged up with flight controllers to discuss the upcoming installation of the Sabatier, which combines carbon dioxide from the Carbon Dioxide Removal Assembly and hydrogen from the Oxygen Generation System to form water and methane.

The water will be recycled by the Water Processor Assembly, and the methane vented overboard.

Shuttle Program Assigns Nov. 1 Launch Date




HOUSTON — NASA space shuttle program managers approved a Nov. 1 launch date for the 11-day STS-133 mission aboard the shuttle Discovery, following a Oct. 6 review of mission preparations.

John Shannon, the shuttle program manager, received a unanimous "go" from the team members to continue with launch preparations.

NASA will host an agency-wide Flight Readiness Review on Oct. 25 at Kennedy Space Center in Florida to set a formal launch date. The FRR will assess the readiness of the International Space Station as well as Discovery for the STS-133 flight.

During the mission, Discovery's six-member crew will deliver the Permanent Multipurpose Module to the station for additional equipment storage. The PMM also will carry Robonaut 2, a humanoid robot that will undergo evaluation as a future external as well as internal assistant to station astronauts.

STS-133 is one of two scheduled missions remaining for the shuttle program. STS-134, using the shuttle Endeavour, is tentatively scheduled for a Feb. 27 launch on the final slated flight.

However, NASA managers are making plans to convert the STS-134 "launch-on-need" rescue mission assigned to Atlantis into an operational mission — if Congress and the White House agree on funding. Atlantis and a crew of four astronauts would carry supplies to the station as STS-135, which would launch in late June if funding is approved.

NASA plans mission to study Mars atmosphere :: Brahmand.com

WASHINGTON (BNS): NASA is planning to launch its Mars Atmosphere and Volatile Evolution Mission (MAVEN) in 2013, to study the Red Planet
in-depth.

The $400-million plus project, will study the fast disappearing atmospheric planet of the planet.

NASA has scheduled the launch of the MAVEN between November 18th and December 7th, 2013. If it is launched on November 18th, it will reach Mars on September 16th, 2014 for a year-long mission.



"Previous observations gave us 'proof of the crime' but only provided tantalizing hints at how the sun pulls it off - the various ways Mars can lose its atmosphere to solar activity," Joseph Grebowsky of NASA's Goddard Space Flight Center in Greenbelt, Md. and project scientist for MAVEN, said.

According to NASA, Mars lost its global magnetic field billions of years ago. Once its planet-wide magnetic field disappeared, its atmosphere was exposed to the solar wind, and could have been gradually stripped away.

Compared to Mars, the atmosphere on Earth is thicker and the planet still has a magnetic field that protects it from the solar radiation.

"Mars can't protect itself from the solar wind because it no longer has a shield, the planet's global magnetic field is dead," Bruce Jakosky of the University of Colorado said.

As the atmosphere thinned, the water on the planet evaporated and was lost to space. Increased ultraviolet radiation would also break water into its component atoms of hydrogen and oxygen.

"MAVEN will examine all known ways the sun is currently swiping the Martian atmosphere, and may discover new ones as well. It will also watch how the loss changes as solar activity changes over a year. Linking different loss rates to changes in solar activity will let us go back in time to estimate how quickly solar activity eroded the Martian atmosphere as the sun evolved," Grebowsky added.

Features on Mars resembling dry riverbeds, and the discovery of minerals that form in the presence of water, indicate that Mars once had a thicker atmosphere. However, it was lost due to exposure to solar radiation that quickly boils away water on the surface.

The MAVEN team will measure the amount of hydrogen compared to the amount of deuterium in Mars' upper atmosphere, which is the planet's present-day hydrogen to deuterium (H/D) ratio. They will compare it to the ratio Mars had when it was young -- the original H/D ratio.

The original ratio is estimated from observations of the H/D ratio in comets and asteroids, which are believed to be pristine, "fossil" remnants of the solar system's formation.

The spacecraft will be developed at the Littleton facility center of Lockheed Martin.

Russia's Soyuz spacecraft docks with ISS



MOSCOW (AFP): A newly-modernised Russian Soyuz spacecraft carrying three astronauts on Sunday docked with the International Space Station (ISS) to double its crew to six, mission control said.

"Capture and docking confirmed. The ISS crew has doubled in size," mission control said, confirming the docking at 4:01 am (local time).


Spokesmen for mission control in Moscow Valery Lydin told the Interfax news agency that docking had taken place automatically and the astronauts would open the hatches and enter the ISS itself three hours after docking.

The Soyuz TMA-M spacecraft is a modernised version of the ship used by Russia to put humans into the space and the first of a new series to have fully digital systems.

The crew includes one of Russia's most experience spacemen, Alexander Kaleri, whose first mission to space was in in March 1992 just after the fall of the Soviet Union to the now defunct Russian space station Mir.

Kaleri has already made four space flights, logging up 610 days in space and almost 24 hours of spacewalks, his last trip an October 2003 mission to the International Space Station.

Joining him are American Scott Kelly, who has made two spaceflights and Oleg Skripochka, who is making his first space flight. They had blasted off early on Friday from Russia's Baikonur cosmodrome in Kazakhstan.

On board the ISS, where they will spend the next five months, they will join Americans Douglas Wheelock and Shannon Walker as well as Russian Fyodor Yurchikhin.

Space hotel project to be launched after contract is signed - Energia



The implementation of the project to build the first space hotel will only start after a contract between Russian state-owned rocket and space corporation Energia and Moscow-based company Orbital Technologies is signed, the Energia head said.

Orbital Technologies on Wednesday announced sky-high plans to launch an orbiting hotel in space by 2015-2016.

"As of today, the company only has an agreement of intent. When we have a firm contract, there will be the terms and engineering design," Vitaly Lopota said.

The project will cost hundreds of millions of dollars, Orbital Tehcnologies' CEO Sergei Kostenko said in late September, adding that Russian and U.S. investors have already been found.

Individuals, professional crews and explorers interested in implementing their own research programs are expected to be the first clients of the commercial tourist hub, Kostenko said then.

So far, several super-rich businesspeople have been the only space tourists, traveling into space with professional cosmonauts, but if the project is implemented the space tourism market is likely to develop rapidly.

Like my friends mentioned we should be careful to not rush this and make a mistake. A successful manned mission is a great achievement but a failure while trying to do so will be the greatest of embarrassments.

quite frankly just like the commonwealth games there seems to be a lack of image of overall management - take for example the straightforward matter of the actual date of launch of the manned mission . In most countries that date is sacred and those whoe organization works night and day if necessary to keep to schedule but on this important isro project , just in this thread alone there are so many alternative launch dates offered by the various authorities ranging from 2015 by isro then 2017 by radhakrishnan - all top officials . ANd in the articles above dr madhavan can be seen quoting 2015 as isro being ready for a manned moon mission - is this the same "organizational capability" that we have seen with the cwg where there are multiple committees each one expecting the other to do the last minute work and no one really overall in charge . I sure hope it isnt.

World's first commercial spaceship makes maiden manned glide flight

MOJAVE, CALIFORNIA (BNS): The efforts to make outer space
a viable tourist destination received a major boost when US company Virgin Galactic's SpaceshipTwo successfully achieved its first piloted glide flight on Sunday.

The spaceship, flown by Pete Siebold and Mike Alsbury, was released from its mothership WhiteKnightTwo at an altitude of 45,000 ft (13.70 kilometers).

"The two main goals of the flight were to carry out a clean release of the spaceship from its mothership and for the pilots to free fly and glide back and land at Mojave Air and Space Port in California," Virgin Galactic said.


Virgin Galactic's SpaceshipTwo, flown by two pilots, has successfully achieved its maiden glide flight.

Sunday's flight test lasted for about 25 minutes. Before the successful flight, the company had exhaustively tested the mothership WhiteKnightTwo which flew for a total of 40 times, including four captive carry flights during which it flew along with the SpaceshipTwo.

SpaceshipTwo, pegged to be the world's first manned commercial spaceship, had successfully completed its maiden captive carry flight test in the California desert in March this year.

The spaceship has been designed to ferry thousands of private astronauts into space. The vehicle could carry up to six passenger astronauts and up to two pilot astronauts into space on a sub-orbital flight.

Once in suborbital space, SpaceshipTwo passengers will be able to view the Earth from portholes next to their seats, or unbuckle their seatbelts and float in zero gravity.

Virgin Galactic chief, billionaire entrepreneur Richard Branson, had last month said that his company was on track to offer commercial space travel in the next 18 months.

Political obstacles for Sea Launch overcome - Energia



International consortium Sea Launch plans to resume Zenit-3SL carrier rocket launches from its floating platform in the Pacific Ocean in 2011, the head of the Russian Rocket and Space Corporation Energia said Monday.

"All political conditions for resuming launches on the Sea Launch program have been met. All commissions in the United States have been passed. A license for 70 launches has been received," Vitaly Lopota said.

"There are enough contracts for satellite launches. The first launch is due at the end of next year," he told journalists.

Sea Launch was created in 1995. It incorporated Energia with a 25% stake, a Boeing subsidiary with 40%, Norwegian company Aker ASA with a 20% stake and Ukraine's SDO Yuzhnoye/PO Yuzhmash with 15%.

Sea Launch announced its bankruptcy in June 2009. In July 2010, Energia subsidiary Energia Overseas Limited (EOL) received 95% in Sea Launch by a bankruptcy court ruling.

A total of 30 rocket launches have been made from the Pacific platform since 1999, with 27 of them successful.

More 'space' for women

Kalpana Chawla may have reached the space via the US but no more will an Indian woman have to take that route. If the Indian Space Research Organisation (ISRO) plans go well, a woman from the country will soon find herself floating in space in a few years.

Sources in the ISRO told Deccan Herald that the space agency is planning to have a woman on-board in space shortly after, if not the first, the manned-mission scheduled for 2015. The ISRO's Human Space flight Programme, which got a go-ahead from the Centre in February 2009, aims at developing and launching an orbital vehicle to carry a two-member crew. In a subsequent mission, the agency planned to carry a three-member crew to space, one of which will be a woman, highly-placed sources from the ISRO said.

"For a nation that has always seen tremendous potential in its women, this will be a launch pad of sorts that will only see more women take part in such activities," a scientist said.The proposal has already taken off with funds coming in from the Centre for pre-project preparations and a three-seater capsule being readied in ISRO's Vikram Sarabhai Space Centre in Thiruvananthapuram. The mission is indigenous, though the capsule is being developed with Russian technology.

Apart from the technical preparations, efforts to ready manpower are also on. About 250 Indian Air Force (IAF) pilots, including women, have been screened though the crew has yet to be handpicked. Once selected, the pilots will be trained to fly an aircraft outside the planet's orbit.

"They will be trained with an accurate simulator and will be checked for the right aptitude and other requirements in line with the international standards," a source pointed out.

The mission to have a woman onboard is being widely discussed in the top chambers of Union Science and Technology Ministry, the Indian Air Force and the Indian Space and Research Organisation, could encourage entry of more women into the fields of scientific research and development, largely considered a male bastion.

Giant star goes supernova, smothered by its own dust: NASA

COLUMBUS, OHIO (BNS): A giant star in a remote galaxy ended its life with a dust-shrouded whimper instead of the more typical bang, says NASA.

Researchers suspect that this odd event -- the first one of its kind ever viewed by astronomers – was more common early in the universe.

It also hints at what we would see if the brightest star system in our Milky Way galaxy exploded, or went supernova.



Using NASA's Spitzer Space Telescope, astronomers worked backward to determine what kind of star could have spawned the supernova and how the dust was able to partly muffle the explosion.

They calculated that the star was probably a giant, at least 50 times more massive than our sun. Such massive stars typically belch clouds of dust as they near the end of their existence.

This particular star must have had at least two such ejections, they determined – one about 300 years before the supernova and one only about four years before it. The dust and gas from both ejections remained around the star, each in a slowly expanding shell.

The inner shell – the one from four years ago – would be very close to the star, while the outer shell from 300 years ago would be much farther away.

The findings have been published in the latest edition of the 'Astrophysical Journal'.

Hubble captures first images of suspected asteroid collision

WASHINGTON (AFP): NASA's Hubble space telescope
has captured what scientists believe are the first images of a collision between two asteroids, the US space agency
has said.

The images, taken from January to May with Hubble's Wide Field Camera 3, show a bizarre X-shaped object, the likes of which astronomers have never seen before, at the head of a comet-like trail of material.

Scientists have dubbed the object in the Hubble images P/2010 A2. It was found cruising around the asteroid belt, a reservoir of millions of rocky bodies between the orbits of Mars and Jupiter.

The 400-foot-wide object in the image is thought to be a remnant of a larger body that collided at about 17,700 kilometres per hour with a smaller rock that the scientists think measured 10 to 15 feet across.

The crash released an explosion with the force of a small atomic bomb and is believed by astronomer David Jewitt of the University of California, Los Angeles, to have happened in February or March 2009.

Until now, astronomers have relied on models to make predictions about the frequency of collisions in space and the amount of dust they produced.

"These observations are important because we need to know where the dust in the solar system comes from and how much of it comes from colliding asteroids as opposed to 'outgassing' comets," Jewitt said.

Asteroid crashes are relatively common -- Jewitt estimates that modest-sized asteroids smash into each other roughly once a year.

But Hubble has achieved yet another feat in its storied space-gazing life by catching this particular collision, which astronomers believe involved two asteroids that were so faint they were unknown before the crash.

The Lincoln Near-Earth Research (LINEAR) Program Sky Survey spotted the comet-like tail of P/2010 A2 in January 2010, before Hubble captured it.

But only Hubble's images discerned the X pattern, which astronomers say offers "unequivocal evidence that something stranger than a comet outgassing had occurred" but are at pains to explain.

It might suggest that the colliding asteroids were not symmetrical, meaning material that was ejected after the impact did not make an even pattern, NASA said.

Astronomers plan to observe P/2010 A2 next year using Hubble, to see how far the dust has been swept back by the Sun's radiation and how the mysterious X-shaped structure has evolved.

American satellite Sirius XM-5 to be launched

MOSCOW (ITAR-TASS): The Proton-M carrier rocket with the American communications satellite Sirius XM-5 will be launched from the Baikonur cosmodrome Thursday.

"The launch of the Proton-M carrier rocket equipped with the Briz-M upper stage is scheduled for 22:53, Moscow time," spokesman for the Khrunichev State Space Research and Production Centre Alexander Bobrenev told Itar-Tass.

The Russian Federal Space Agency (Roskosmos) specified that the "area of the fall of the spent first stage of the carrier rocket is in the Karaganda region (Kazakhstan), the second stage and nose cone - in the Republic of Altai (Russia) and the third stage - in the Pacific Ocean."

"The total orbiting time from the moment of the rocket's blastoff to the separation of the spacecraft from the upper stage will be 09 hours and 12 minutes," Roskosmos noted. The satellite will take the station point on the geostationary orbit 85.2 degrees West longitude.


The Proton-M carrier rocket

The Sirius XM-5 spacecraft was created by Space Systems/ Loral on the order of the American satellite radio broad- casting SIRIUS XM Radio that has 20 million mobile and stationary subscribers. The satellite's design useful life in orbit is 15 years, its mass is 5,980 kilograms.

The Proton-M carrier rocket and Briz-M upper stage were designed by the Khrunichev Centre. The rocket is three-stage, liquid-propelled. Its lift-off mass is about 700 tonnes. The Proton rockets are marketed on the space services market by International Launch Services (ILS). Khrunichev holds the controlling stake in ILS.

"The coming launch will become the ninth for the Proton-M carrier rocket in 2010 and 360th in its flight history," the Khrunichev Centre recalled.

It will be the sixth for ILS in 2010 and the 62nd since the beginning of commercial exploitation the Proton in April 1996.

The Khrunichev State Research and Production Space Centre was created by an RF presidential decree of 7 June 1993 on the base of the largest producers of aerospace and rocket technology
: the Khrunichev Machine-building Plant and the Salyut Design Bureau.

Khrunichev State Research and Production Space Centre is one of the world's largest aerospace corporations leading the international market of space services.

The Khrunichev Centre manufactured all the Russian manned orbital stations: Salyut, Mir and Almaz and also all the heavy modules that docked to the orbital stations and the three- seater recoverable spacecraft.

Scientists explore galaxies booming with star births

COPENHAGEN, DENMARK (BNS): Scientists from Niels Bohr Institute have studied the distant galaxies, which form around 1,000 new stars a year -- a 1,000 times more than our own galaxy, the Milky Way, according to a report.

These galaxies are the most active star-forming galaxies in the Universe.

Monthly Notices of the Royal Astronomical Society has published the findings in their research journals.

"The galaxies are located in the far distant Universe -- when the universe was 3 billion years old (equivalent to only 20 percent of its current age). It is a period of the Universe when the galaxies were very active, almost teenager-like and out of control," Science Daily quoted Thomas R. Greve, Associate professor in astrophysics at Dark Cosmology Centre, Niels Bohr Institute at the University of Copenhagen as saying.

According to the website, Thomas R. Greve has studied distant galaxies with the support of researchers from Expanded Very Large Array (an astronomical observatory in New Mexico) and Royal Observatory, Edinburgh and Durham University in England.

The astronomical observatory consists of 27 parabolic antennas, each of which have a diameter of 25 meters and can measure radio waves from distant objects.

Data from each antenna is combined electronically so that the final measurements have an angular resolution equivalent to a single antenna with a diameter of 36 km and sensitivity equal to that of a single antenna with a diameter of 130 meters.

"We have measured the CO levels, that is to say carbon monoxide, which is one of the most common molecules in the universe, after the hydrogen molecule, H2. Using the measurements we have calculated how much gas there is in the galaxy and it turns out there are extremely large amounts of gas in these galaxies," he added.

Gas is the raw material used in the Universe to form stars.

Our galaxies are almost filled with gases, these gases becomes so dense that they collapses into a ball of glowing gas, which forms a new star -- the cloud almost 'explodes' in a cosmic firework display of new stars.

The measurements of the morphology of the gas also suggest that these galaxies are usually bigger in size and irregular in shape.

After developing for several hundred of billion years, these galaxies transform into an intense star and become mature, regular, elliptical shaped galaxies like Milky Way.

New system developed for docking and capturing space satellites

MADRID (BNS): Scientists at the Universidad Carlos III de Madrid (UC3M) have recently developed a new type of automated satellite docking and capture system, which allows robots to autonomously trap target spacecrafts.

The initiative is called "Docking and Capture of Satellites through computer vision," or ASIROV for short, according to a UC3M news release.

Within this framework, the scientists have developed algorithms and strategies to dock and capture a disabled satellite through the use of a space vehicle, called a "chaser", which autonomously carries out this function.

"By using this methodology, we attempt to carry out all the phases of a satellite inspection and maintenance mission with another autonomous vehicle equipped with a robotic system for capture and control," Mohamed Abderrahim, head of this research study, UC3M Department of Automated Systems Engineering, in the release.

The university itself is not directly involved with the manufacture or launching of the rescue satellites, experts say. Their involvement deals exclusively with developing the intricate algorithms needed.

These navigation algorithms, based on vision techniques, are capable of indentifying the objects of the search among various objects present, estimating their position and orientation.

The scientists, while doing the research, have constructed a small bank of tests which allow them to simulate a scenario of this kind. They first designed vision algorithms which employ satellite model vertices as characteristic points. Then, they perfected the technique to design a new vision algorithm that uses the information about the texture around the points of interest of the image to associate them with the points in the model.

"The latter technique is quite robust against noise, changes in the background and variations in illumination," added Abderrahim.

He also stated that, "today there is a growing need to provide satellite maintenance services, without relying on manned missions, which are very costly and involve risks. Robotics is the natural solution."

Currently, the researchers are in contact with the Spanish company, SENER, as they explore paths for collaboration to implement this idea, with the aim of extending the working life of communication satellites to up to twelve years of service in space.

India to build neutrino observatory

http://www.upi.com/Science_News/2010/10/20/India-to-build-neutrino-observatory/UPI-64701287621378/

NEW DELHI, Oct. 20 (UPI) -- India says it will build a more than quarter-billion-dollar underground facility to join the worldwide search for elusive neutrino particles.

The country's Environment and Forests Ministry has given the Atomic Energy Department the go-ahead for the neutrino observatory to be built in the Bodi West hills on the coast of Tamil Nadu state, the BBC reported Wednesday.

The $270 million facility will be only the fifth observatory in the world dedicated to detecting the almost mass-less elementary particles, sometimes called "ghost particles."

About 90 scientists from 26 organizations will be involved in the Indian Neutrino Observatory, organizers say.

A cavern and a mile-long tunnel will be carved under the hills where researchers will use a 55,000-ton electromagnet to carry out experiments.

"Neutrinos are tiny, neutral, elementary particles found abundantly in the cosmos. The sun and all other stars produce neutrinos abundantly through nuclear fusion and decay processes. Neutrinos rarely interact and pass unhindered through all objects including the Sun and the Earth," observatory Chairman Chinnaraj Joseph Jaikuma says.

"We have chosen a place where natural rock cover of over 1,000 meters (3,200 feet) thickness is available. The hard rocks will act as a natural filter allowing only the neutrino particles to reach the laboratory," he says.

India to build observatory to study neutrino particles

India's Department of Atomic Energy has been given clearance to build a multi-million dollar underground facility to study particles called neutrinos.

The environment and forests ministry gave the go-ahead for the observatory to be built in the Bodi West hills on the coast of southern Tamil Nadu state.

The facility costing $270m will be only the fifth of its kind in the world.

Correspondents say it is one of the biggest and most ambitious scientific projects ever undertaken by India.

One of the scientists leading the project says it could help India gain a leading role in the field of particle research.

Neutrinos are elusive, nearly mass-less elementary particles, sometimes called "ghost particles".

'Natural rock cover'
About 90 scientists from 26 organisations will be involved in the Indian Neutrino Observatory (INO), organisers say.

Construction work is expected to begin soon.

The facility will be built in Theni district under the Western Ghats mountains, about 110km (70 miles) south of the temple town of Madurai.

A cavern to house the lab and a 2km-long tunnel will be built under the hills over the next few years. Scientists will use a 50-kiloton electromagnet to carry out experiments.

"Neutrinos are tiny, neutral, elementary particles found abundantly in the cosmos. The Sun and all other stars produce neutrinos abundantly through nuclear fusion and decay processes. Neutrinos rarely interact and pass unhindered through all objects including the Sun and the Earth," says Dr Chinnaraj Joseph Jaikumar, chairman of the INO cell in Madurai.

"We have chosen a place where natural rock cover of over 1,000m thickness is available. The hard rocks will act as a natural filter allowing only the neutrino particles to reach the laboratory."

Dr Jaikumar expects the project to enhance understanding of the universe and the Earth's structure, as well as volcanic activity and how tsunamis are formed.

A site near the southern hill station of Ooty was originally chosen for the project, but did not get clearance after local protests.

Activists near Theni fear locals may suffer restricted access to the area owing to the sensitivity of the project.

There's a growing anxiety in India about the stagnancy in Russian technology and R & D which has crept in gradually, post the cold war era.
IMO, the international power equations still suggest that for the next 5 years at least, Russia has a lot to offer to India. But after that I think it is going to be an equal 1 on 1 partnership of working together. Not a provider - consumer typo anymore.
