China to help Bolivia launch satellite by 2013

La Paz, Oct 23 (AFP) Bolivia signed a memorandum of understanding today with Chinese officials for the construction and launch of a communications satellite.

President Evo Morales said the USD 300-million satellite, whose design is set to be completed by March 2010, would be named after Tupac Katari, a Bolivian indigenous leader who fought against Spanish colonial rule.

A Bolivian delegation will travel to China to seal the deal and spur the satellite's construction, ready for a 2013 launch.

The memorandum was also signed by representatives of the International Telecommunication Union (ITU).

NASA is 'go' for crucial rocket test

fullstory

Washington, Oct 25 (AFP) NASA is set to blastoff a prototype rocket on Tuesday that carries hopes of returning humans to the Moon, and for the first time to Mars, despite deep uncertainty about the program's future.

The space agency said everything is in order for Tuesday's two-minute, 30-second test of the Ares I-X rocket, a first look at the launch vehicle designed to replace NASA's aging space shuttle fleet.

It is "an early opportunity to test and prove flight characteristics, hardware, facilities and ground operations associated with the Ares I," the space agency said.

Data will be collected from over 700 sensors spread across Ares I-X, providing a stream of information that will be scrutinised for months.

But more rides on the launch than data.

It is the culmination of three years work on Constellation, a human space flight program conceived by former president George W.

The Associated Press: Bad weather could interfere with NASA test flight

Bad weather could interfere with NASA test flight

By MARCIA DUNN (AP) – 1 hour ago

CAPE CANAVERAL, Fla. — NASA's newest rocket is on the verge of blasting off on a test flight.

The Ares I-X rocket is set to lift off Tuesday morning. But forecasters say there's a 60 percent chance that rain and clouds could delay the experimental flight. It's already a half-hour late because of extra time needed for the countdown.

This is the first step in NASA's effort to return astronauts to the moon.

The flight will last two minutes. Parachutes will drop the first-stage booster into the Atlantic for recovery. The upper portion of the rocket — all fake parts — will fall uncontrolled into the ocean.

NASA expects to learn a lot, even if it's for another type of rocket. The White House is re-evaluating the human spaceflight program.

NASA launches world's tallest rocket- ET Cetera-News By Industry-News-The Economic Times

NASA launches world's tallest rocket
28 Oct 2009, 2200 hrs IST, AGENCIES

CAPE CANAVERAL: NASA launched Wednesday a new rocket it hopes will one day return astronauts to the Moon on a two-minute test flight.

The Ares I-X rocket blasted off at 11:30 am (1530 GMT) from Cape Canaveral in Florida after a series of delays due to poor weather conditions.

Standing 327 feet (100 meters) tall, the Ares I-X is the longest rocket ever built, and it was the first spacecraft the Kennedy Space Center has launched other than a shuttle in 30 years.

The Ares I-X is a prototype of the Ares I, which along with a new exploration vehicle called the Orion is intended to replace NASA's aging shuttle fleet that is due to be retired in 2010.

NASA aims to gather data from more than 700 sensors placed along the rocket to enable engineers to fine-tune their design.

Ares and Orion are part of Constellation, NASA's grand program to send astronauts back to the Moon by 2020, and then on to Mars and other destinations.

The test flight is crucial as the White House is considering a report ordered by President Barack Obama's administration that raises concerns about Ares and the whole Constellation project.

Russia's "Nuclear Spaceship"

MOSCOW (AP) -- Russia's space agency is planning to build a new spaceship with a nuclear engine, its chief said Wednesday.

Anatoly Perminov told a government meeting Wednesday that the preliminary design could be ready by 2012. He said it will then take nine more years and 17 billion rubles ($600 million, 400 million euros) to build the ship.

"The implementation of this project will allow us to reach a new technological level surpassing foreign developments," Perminov told a meeting which focused on communications and space technologies.

Russian President Dmitry Medvedev urged the Cabinet to consider providing the necessary funding.

Russia's "Nuclear Spaceship" - AskMen.com

"It's a very serious project," Medvedev said. "We need to find the money."

Perminov's ambitious statement contrasted with the current state of the Russian space program, and sounded more like a plea for extra government funds than a detailed proposal.

Russia is using 40-year old Soyuz booster rockets and capsules to send crews to the International Space Station. Development of a replacement rocket and a prospective spaceship with a conventional propellant has dragged on with no end in sight.

Perminov described the proposed spaceship as a "unique breakthrough project," but offered few details.

He said that the ship will have a megawatt-class nuclear reactor, as opposed to small nuclear reactors that powered Soviet satellites. The Cold-War era Soviet spy satellites had reactors which produced just a few kilowatts of power and had a lifespan of just about a year.

Perminov didn't say what the new spaceship will be used for.

He and other officials have said that Russia needs a new spaceship to replace the old Soyuz for missions in Earth orbit, but they only have talked about a ship powered by a conventional rocket fuel so far.

Russian space agency also has mulled over prospective future missions to the moon and Mars, but hasn't yet set a specific time frame yet.

Indian leader and space scientist advocates cooperation, not competition in space

HUNTSVILLE, AL - Former Indian President Dr. A.P.J. Abdul Kalam had an answer here Wednesday to the question of how to afford space exploration.

Kalam, 78, has also been a key figure in Indian nuclear weapons technology, a field he believes vital to India's role as an emerging world superpower.

Kalam spent much of Wednesday in Huntsville and spoke to reporters after touring the National Space Science and Technology Center on the campus of the University of Alabama in Huntsville.

"Huntsville is well-known for space research," Kalam said. "I am here to look at the university research."

Kalam said he was impressed and "very happy with the research focus" here, particularly in the field of "space physics."

"There definitely could be a collaboration" between UAH and Indian schools, he said, and also increased collaboration between India and the United States.

Kalam was asked about the future of the Indian space program, often cited by American political leaders as a competitive reason to continue funding NASA and the American space program.

He immediately referred to his "World Space Vision 2050," which urges international cooperation to lower the cost of lifting objects into orbit.

Kalam has proposed the development and use of reusable rockets.

"Scientific breakthroughs in air breathing propulsion systems may lead to a revolution in space transportation," Kalam has said. "Space communities of the world have a huge stake in such breakthrough research in advanced interdisciplinary and inter-institutional collaboration."

Kalam has also proposed the creation of a World Space Council to coordinate the planning and space efforts of numerous nations. He has also said that space must remain free of weapons.

Kalam was accompanied on his tour by numerous Indian-American researchers and professors. He was escorted by former Alabama First Lady Marsha Folsom and her husband, former Gov. Jim Folsom Jr.

In India, Kalam is widely respected as a an aerospace engineer and political leader but also as a visionary. He is known for his inspirational writings, including his biography "Wings of Fire," and for his poetry.

He was asked if Huntsville might figure in a future poem. It's very possible, Kalam said, because the ideas were certainly flowing here.

NASA's booster rocket damaged in test flight

fullstory

Cape Canaveral, Oct 30 (AP) The booster rocket used in a test flight was badly dented when it fell into the Atlantic, NASA has said.

The new Ares I-X rocket was launched on a brief flight on Wednesday. NASA officials said yesterday that the first-stage booster was found to be dented near the bottom when it was recovered from the ocean.

NASA spokesman Allard Beutel said there's still no official word on whether all three parachutes on the booster deployed properly. A parachute failure could account for the damage.

The Ares I-X is a prototype of what's supposed to replace the space shuttles and ultimately fly to the moon.

Shuttle managers, meanwhile, have chosen November 16 for the launch of Atlantis on a space station mission.

India's space ambitions taking off - washingtonpost.com

India's space ambitions taking off



In this seaside village, the children of farmers and fishermen aspire to become something that their impoverished parents never thought possible: astronauts.

Through community-based programs, India's space agency has been partnering with schools in remote areas such as this one, helping to teach students about space exploration and cutting-edge technology. The agency is also training thousands of young scientists and, in 2012, will open the nation's first astronaut-training center in the southern city of Bangalore.

"I want to be prepared in space sciences so I can go to the moon when India picks its astronauts," said Lakshmi Kannan, 15, pushing her long braids out of her face and clutching her science textbook.

Lakshmi's hopes are not unlike India's ambitions, writ small. For years, the country has focused its efforts in space on practical applications -- using satellites to collect information on natural disasters, for instance. But India is now moving beyond that traditional focus and has planned its first manned space mission in 2015.

The ambitions of the 46-year-old national space program could vastly expand India's international profile in space and catapult it into a space race with China. China, the only country besides the United States and Russia to have launched a manned spacecraft, did so six years ago.

"It's such an exciting time in the history of India's space program," said G. Madhavan Nair, a rocket scientist and the outgoing chairman of the national space agency, the Indian Space Research Organization (ISRO). "More and more bright young Indian scientists are calling us for jobs. We will look back on this as a turning point."

The ascendancy of India's space program highlights the country's rising ambitions on the world stage, as it grows economically and asserts itself in matters of diplomacy.


Politicians once dismissed the space program as a waste. Activists for India's legions of poor criticized additional funding for the program, saying it was needless decades after the American crew of Apollo 11 had landed on the moon. Now, however, the program is a source of prestige.

Last year, India reached a milestone, launching 10 satellites into space on a single rocket. Officials are positioning the country to become a leader in the business of launching satellites for others, having found paying clients in countries such as Israel and Italy. They even talk of a mission to Mars.

India's program is smaller in scope than China's and is thought to receive far less funding. It is also designed mostly for civilian purposes, whereas experts have suggested that China is more interested in military applications. (The Communist Party has said its goal is peaceful space exploration.)

"A human space flight with an eventual moon mission is a direct challenge to China's regional leadership," said John M. Logsdon, professor emeritus of political science and international affairs at George Washington University's Space Policy Institute. "China is still the leader. India has yet to diminish China's space stature. But India is indeed seeking a higher global profile."

India now has among the world's largest constellations of remote-sensing satellites. They are sophisticated enough to distinguish healthy coconuts from diseased ones in this region's thick palms. They can also zero in on deadly mosquitoes lurking in a patch of jungle.

In September, a NASA device aboard India's first lunar probe detected strong evidence of water on the moon -- a "holy grail for lunar scientists," as Jim Green, director of the Planetary Science Division at NASA headquarters in Washington, put it.

The partnership with Americans was particularly gratifying to Indians, given recent bilateral history. After New Delhi conducted nuclear tests in 1998, the United States imposed sanctions denying India access to certain technology in a bid to curb its ability to launch nuclear rockets, said Theresa Hitchens, a space expert who is director of the U.N. Institute for Disarmament Research in Geneva.

"Space launchers and ballistic missiles are quite similar from a technical perspective," she said.

Many of the sanctions have been lifted, and India and the United States last year signed a historic civilian nuclear agreement, lifting a 30-year ban on bilateral nuclear trade.

"The scientists at ISRO and NASA have always had deep respect for each other. But it was politics and bureaucracy that stood in the way of great science," said Pallava Bagla, co-author of "Destination Moon: India's Quest for the Moon, Mars and Beyond."

As India's space program barrels ahead, experts fear that NASA is losing ground. The space agency's human spaceflight program is facing budget cuts, as well as basic questions about where to go and how to get there.

After NASA's aging space shuttle retires in 2010, it will be five years before the United States will have another spacecraft that can reach the international space station.

The United States may have to buy a seat to the moon on an Indian spaceship, said Rakesh Sharma, India's first astronaut, who in 1984 was aboard the Soviet Union's Soyuz T-11 space shuttle. "Now that would be something," Sharma said. "Maybe budget cuts could usher in an era of more cooperation rather than competition and distrust."

Bhilai steel plant rolls special steels for space vehicles- Steel-Ind'l Goods / Svs-News By Industry-News-The Economic Times

KOLKATA: Bhilai Steel Plant (BSP) has for the first time rolled high strength special steels used in construction of space vehicles. While the steel
slabs were developed by Mishra Dhatu Nigam (Midhani), a defence ministry arm, these plates of 9.5 mm thickness were rolled for the first time at BSP's Plate Mill recently. The rolled plates are used for manufacturing the main body of India’s indigenous space vehicles.

"These plates find application across the aerospace sector but its commercial use is largely restricted to critical areas of strategic significance," a top source told ET.

These plates are much stronger than mild steel sheets that find application in consumer durables and auto sector, for instance. However, in terms of value, these plates are likely to be many times costlier than hot rolled coils.

Such steels are made out of special alloys and are capable of withstanding metal fatigue which occurs due to tremendous changes in heat and atmospheric pressure on the space craft when it returns to orbit. Steel is widely used in construction of space shuttles along with metals like aluminium, titanium and other high grade materials.

"Bhilai has also been making special grade plates used to manufacture the hull of India’s aircraft carrier warships and submarines," a BSP official said. the plant also manufacturers the widest and thickest plates and also exports it to other countries.

Plates from Bhilai’s Plate Mill are also used for manufacturing boilers, in hydro-electric projects, heavy machinery equipment and as a base for heavy construction including platforms and bridges, including those on the Jammu-Udhampur rail link.

As part of its modernisation programme, BSP has installed a new slab caster and a second set of RH degasser and ladle furnace in the secondary refining facilities of its Steel Melting Shop II.

Russian rocket puts 2 European satellites into orbit | Top Russian news and analysis online | 'RIA Novosti' newswire

MOSCOW, November 2 (RIA Novosti) - Two European satellites, the SMOS spacecraft and the Proba-2 mini-satellite, were successfully put into orbit by a Rokot carrier rocket on Monday, a spokesman for Russia's Federal Space Agency said.

The satellites were launched from the Plesetsk space center in northwest Russia earlier on Monday.

"The launch of the rocket and the insertion [into orbit] took place in accordance with the schedule," the Roscosmos spokesman said.

The 665-kg SMOS (Soil Moisture and Ocean Salinity) spacecraft, being put into the orbit at an altitude of 756 km (470 miles), is to produce global maps of high resolution and sensitivity showing variations in soil moisture and saline levels in the world's oceans. The mission is part of ESA's Earth Explorer Envelope Program.

The 130-kg Proba-2 (Project for On-Board Autonomy) research satellite will test new technologies for autonomous space missions for ESA's Technology Directorate.

The Rokot launch vehicle is a modified version of the Russian RS-18 (SS-19 Stiletto) intercontinental ballistic missile. It uses the two original lower stages of the ICBM, in conjunction with a Breeze-KM upper-stage for commercial payloads.

This is the third Rokot launch of 2009. In March, a Rokot launch vehicle successfully put into orbit the European GOCE satellite, which will measure and map the Earth's gravitational field. In July, a Rokot with three Russian Cosmos-series military satellites was launched by Russia's Space Forces from the Plesetsk space center.

Russia develops design for spaceship with nuclear engine



The Russian Federal Space Agency Roscosmos has developed a design for a piloted spacecraft powered by a nuclear engine, the head of the agency said on Wednesday.

“The project is aimed at implementing large-scale space exploration programs,” Anatoly Perminov said at a meeting of the commission on the modernization of the Russian economy.
He added that the development of Megawatt-class nuclear space power systems (MCNSPS) for manned spacecraft was crucial for Russia if the country wanted to maintain a competitive edge in the space race, including the exploration of the Moon and Mars.

Perminov said that the draft design of the spacecraft would be finalized by 2012, and the financing for further development in the next nine years would require an investment of at least 17 billion rubles (over $580 million).

Anatoly Koroteyev, president of the Russian Academy of Cosmonautics and head of the Keldysh research center, earlier said that the key scientific and technical problem in sending manned missions to the Moon and Mars was the development of new propulsion systems and energy supplies with a high degree of energy-mass efficiency.

The current capabilities of the Russian space industry are clearly insufficient either to set up a permanent base on the Moon or accomplish an independent manned mission to Mars, he said.

'Mishra Dhatu Nigam Ltd' to supply materials for Manned Space Mission

Mishra Dhatu Nigam Ltd (Midhani) to supply materials for Manned Space Mission

The Hindu : HYDERABAD.Thursday, November 12, 2009

With India setting its sights on a manned space mission, the city-based Mishra Dhatu Nigam Ltd. (Midhani), a Mini Ratna company, has geared up to meet Indian Space Research Organisation’s requirements. It has started upgrading facilities and critical materials required for the spacecraft.

Intensive characterisation and vigorous testing of the heat-resistant cobalt super alloys to withstand elevated temperatures of up to 350 degree C were being carried out. The super alloys would be used in the exhaust cones of the spacecraft.

The facilities were being upgraded to increase the production of the materials, the company’s Chairman and Managing Director, M. Narayana Rao, told The Hindu here. The company had supplied super and titanium alloys for the Moon Impact Probe of Chandrayaan-1.

Midhani has also chalked out a plan to increase production of the critical materials required for the three-stage nuclear power programme, space and defence sectors by adopting a two-pronged strategy of expanding indigenous capability and reducing vulnerability to imported equipment.

After supplying about 400 tonnes of special steel to each of the 235 MWe (PHWR) nuclear reactors in the first stage, Midhani commenced production of ‘Superfer 800 L’ ( iron-based super alloy) for the steam generation tubes in the first stage reactors and core steel for use in Fast Breeder Reactors in the second stage. Besides Midhani, only two other companies in the world — an Italian and a French — are producing ‘Superfer 800 L.’

Mr. Rao said plans were afoot to produce materials for the Fusion Reactor of International Thermonuclear Experimental Reactor (ITER). He said the company also developed special steel of ultra-high strength for use in rocket motor casings of Agni, Akash and Prithvi missiles.

A handful of countries are producing this steel. But the one produced by Midhani had higher fracture toughness, he claimed. The company also supplied super alloys, titanium steels for aero-engines and aircraft components, among others, for Light Combat Aircraft, naval applications and the armour of the Arjun Tank.

As part of meeting another major demand for defence and space applications, Midhani is setting up a Rs.400-crore ‘Hot Plate Mill’ for rolling of wide plates.

The Associated Press: Splash! NASA moon strikes found significant water

Splash! NASA moon strikes found significant water

By ALICIA CHANG (AP) – 51 minutes ago

LOS ANGELES — It turns out there's lots of water on the moon — at least near the lunar south pole. The discovery announced Friday comes from an analysis of data from a spacecraft NASA intentionally crashed into the moon last month. "Indeed, yes, we found water. And we didn't find just a little bit, we found a significant amount," said Anthony Colaprete, the mission's principal investigator at NASA's Ames Research Center.

The lunar impact kicked up at least 25 gallons of water and that's only what scientists can see, Colaprete said.

Having an abundance of water on the moon would make it easier to set up a base camp for astronauts by providing drinking water and an ingredient for rocket fuel.

The latest finding is further evidence that the moon is not the dry, barren place it appears and could reinvigorate scientific interest.

"This is not your father's moon," said Greg Delory of the University of California, Berkeley, who was not part of the research. "Rather than a dead and unchanging world, it could in fact be a very dynamic and interesting one."

Delory said the next focus should be to figure out where the water comes from and how much of it there is.

NASA's Lunar Crater Observation and Sensing Satellite, or LCROSS, last month slammed into one of moon's permanently shadowed craters near the south pole to study whether ice was buried underneath.

The mission actually involved two moon shots. First, an empty rocket hull slammed into the Cabeus crater. A shepherding spacecraft recorded the drama live before it also crashed into the same spot four minutes later.

Though scientists were overjoyed with the plethora of data beamed back to Earth, the mission was a public relations dud. Space enthusiasts who stayed up all night to watch the spectacle did not see the promised debris plume in the initial images.

NASA scientists had predicted the twin impacts would spew six miles of dust into space. Instead, images revealed just a mile-high plume.

Scientists spent a month analyzing data from the spacecraft's spectrometers, instruments that can detect strong signals of water molecules in the plume.

Previous spacecraft have detected the presence of hydrogen in lunar craters near the poles, which could be evidence of ice. In September, scientists reported finding tiny amounts of water mixed into the lunar soil all over the lunar surface.

"We've had hints that there is water. This was almost like tasting it," said Peter Schultz, professor of geological sciences at Brown University and a co-investigator on the LCROSS mission.

Mission scientists said it would take more time to tease out what else was kicked up in the moon dust.

It's Official: Water Found on the Moon

Since man first touched the moon and brought pieces of it back to Earth, scientists have thought that the lunar surface was bone dry. But new observations from three different spacecraft have put this notion to rest with what has been called "unambiguous evidence" of water across the surface of the moon.

The new findings, detailed in the Sept. 25 issue of the journal Science, come in the wake of further evidence of lunar polar water ice by NASA's Lunar Reconnaissance Orbiter and just weeks before the planned lunar impact of NASA's LCROSS satellite, which will hit one of the permanently shadowed craters at the moon's south pole in hope of churning up evidence of water ice deposits in the debris field.

The moon remains drier than any desert on Earth, but the water is said to exist on the moon in very small quantities. One ton of the top layer of the lunar surface would hold about 32 ounces of water, researchers said.

"If the water molecules are as mobile as we think they are — even a fraction of them — they provide a mechanism for getting water to those permanently shadowed craters," said planetary geologist Carle Pieters of Brown University in Rhode Island, who led one of the three studies in Science on the lunar find, in a statement. "This opens a whole new avenue [of lunar research], but we have to understand the physics of it to utilize it."

Finding water on the moon would be a boon to possible future lunar bases, acting as a potential source of drinking water and fuel.

Apollo turns up dry

When Apollo astronauts returned from the moon 40 years ago, they brought back several samples of lunar rocks.

The moon rocks were analyzed for signs of water bound to minerals present in the rocks; while trace amounts of water were detected, these were assumed to be contamination from Earth, because the containers the rocks came back in had leaked.

"The isotopes of oxygen that exist on the moon are the same as those that exist on Earth, so it was difficult if not impossible to tell the difference between water from the moon and water from Earth," said Larry Taylor of the University of Tennessee, Knoxville, who is a member of one of the NASA-built instrument teams for India's Chandrayaan-1 satellite and has studied the moon since the Apollo missions.

While scientists continued to suspect that water ice deposits could be found in the coldest spots of south pole craters that never saw sunlight, the consensus became that the rest of the moon was bone dry.

But new observations of the lunar surface made with Chandrayaan-1, NASA's Cassini spacecraft, and NASA's Deep Impact probe, are calling that consensus into question, with multiple detections of the spectral signal of either water or the hydroxyl group (an oxygen and hydrogen chemically bonded).

Three spacecraft

Chandrayaan-1, India's first-ever moon probe, was aimed at mapping the lunar surface and determining its mineral composition (the orbiter's mission ended 14 months prematurely in August after an abrupt malfunction). While the probe was still active, its NASA-built Moon Mineralogy Mapper (M3) detected wavelengths of light reflected off the surface that indicated the chemical bond between hydrogen and oxygen — the telltale sign of either water or hydroxyl.

Because M3 can only penetrate the top few millimeters of lunar regolith, the newly observed water seems to be at or near the lunar surface. M3's observations also showed that the water signal got stronger toward the polar regions. Pieters is the lead investigator for the M3 instrument on Chandrayaan-1.

Cassini, which passed by the moon in 1999 on its way to Saturn, provides confirmation of this signal with its own slightly stronger detection of the water/hydroxyl signal. The water would have to be absorbed or trapped in the glass and minerals at the lunar surface, wrote Roger Clark of the U.S. Geological Survey in the study detailing Cassini's findings.

The Cassini data shows a global distribution of the water signal, though it also appears stronger near the poles (and low in the lunar maria).

Finally, the Deep Impact spacecraft, as part of its extended EPOXI mission and at the request of the M3 team, made infrared detections of water and hydroxyl as part of a calibration exercise during several close approaches of the Earth-Moon system en route to its planned flyby of comet 103P/Hartley 2 in November 2010.

Deep Impact detected the signal at all latitudes above 10 degrees N, though once again, the poles showed the strongest signals. With its multiple passes, Deep Impact was able to observe the same regions at different times of the lunar day. At noon, when the sun's rays were strongest, the water feature was lowest, while in the morning, the feature was stronger.

"The Deep Impact observations of the Moon not only unequivocally confirm the presence of [water/hydroxyl] on the lunar surface, but also reveal that the entire lunar surface is hydrated during at least some portion of the lunar day," the authors wrote in their study.

The findings of all three spacecraft "provide unambiguous evidence for the presence of hydroxyl or water," said Paul Lucey of the University of Hawaii in an opinion essay accompanying the three studies. Lucey was not involved in any of the missions.

The new data "prompt a critical reexamination of the notion that the moon is dry. It is not," Lucey wrote.

Where the water comes from

Combined, the findings show that not only is the moon hydrated, the process that makes it so is a dynamic one that is driven by the daily changes in solar radiation hitting any given spot on the surface.

The sun might also have something to do with how the water got there.

There are potentially two types of water on the moon: that brought from outside sources, such as water-bearing comets striking the surface, or that that originates on the moon.

This second, endogenic, source is thought to possibly come from the interaction of the solar wind with moon rocks and soils.

The rocks and regolith that make up the lunar surface are about 45 percent oxygen (combined with other elements as mostly silicate minerals). The solar wind — the constant stream of charged particles emitted by the sun — are mostly protons, or positively charged hydrogen atoms.

If the charged hydrogens, which are traveling at one-third the speed of light, hit the lunar surface with enough force, they break apart oxygen bonds in soil materials, Taylor, the M3 team member suspects. Where free oxygen and hydrogen exist, there is a high chance that trace amounts of water will form.

The various study researchers also suggest that the daily dehydration and rehydration of the trace water across the surface could lead to the migration of hydroxyl and hydrogen towards the poles where it can accumulate in the cold traps of the permanently shadowed regions.
