ISRO General News and Updates

[rishivashista13]

it will get disfunctional cause the ESA is withdrawing it support to ISS,, their fund and work sahre in maintaining the ISS was significant,without ESA support all work and Fund load will go to USA/NASA , making it really costly for them..
russians are also going to undock there entire Modules in ISS and are planning there own independet space station by expanding it furhter(they have big plans)..

earlier plan was to deorbit it and burn it in atmosphere, but now what i am hearing is that they willl sell it to some private companies, using it for space tourism.

Awesome times are ahead..

Space tourism will be great idea [emoji4]
Great place to visit .
And greatest place for educational trip for students .

Chinese Media on India's Successful Test of SCRAMJET Engine

Once a satellite is placed in its permanent orbit , does it require more fuel to operate ?

Sent from my Micromax Q380 using Tapatalk

Because the orbits decay, due to gravity, tidal forces, and atmospheric drag. Then you need fuel to re-adjust orbits.

yeah the circling motion of the satellite is actually constant falling with circular path isnt it .

• India is yet to become a member of the international space station.

@LETHALFORCE @Akask kumar @rishivashista13 @airtel @sayareakd
After former ISRO chief's remark, human spaceflight getting momentum and looks that India is going to refuel the satellite.:biggrin2:
And refueling satellite means India will also be able to make and run space stations in a relatively shorter developmental period whenever develops heavy launchers.

Story of the Week - Indian Space Research Organization
ISRO’s Scramjet Engine Technology Demonstrator Successfully Flight Tested

Preparations on for launch of GSLV Mark II

THIRUVANANTHAPURAM: Buoyed by the success of the ISRO's Sramjet engine test on Sunday, Scientists of Vikram Sarabhai Space Centre (VSSC) and Liquid Propulsion Systems Centre (LPSC) have begun preparations for the launch of GSLV Mark II scheduled for Sep 8.

"Now, the preparations are on for the GSLV Mark II mission on Sept 8 for the launch of INSAT-3DR, an Indian satellite for weather forecast, search and rescue information. It will be the second flight using the indigenously developed cryogenic engine after it was successfully used for the first time to launch GSLV-D5 in 2014," VSSC director K Sivan told TOI.

Success of Scramjet engine test towards the realisation of Air Breathing Propulsion System (ABPS) using hydrogen as fuel and oxygen from atmospheric air as oxidiser is a milestone in developing a critical technology and that boosts the confidence for the other launches too, he said. It was fitted into an Advanced Technology Vehicle (ATV) based on advanced sounding rocket at hypersonic speed of Mach 6 or six times the speed of sound.

"Such propulsion technology of scramjet engine can power the advanced Reusable Launch Vehicle and other space launches at hypersonic speed in future. It will cut down the cost of space travel by at least one tenth making space launches more economical for ISRO," he reiterated.

With the success of Scramjet engine, India has joined the elite club of space faring nations including the US, Russia and European Space Agency, VSSC scientists said. Twin Scramjet engines were mounted on the back of the second stage of the two-stage ATV. Once the second stage reached the desired conditions for engine `Start-up', necessary actions were initiated to ignite the Scramjet engines and they functioned for about five seconds. After a flight of about 300 seconds, the vehicle touched down in the Bay of Bengal, approximately 320 km from Sriharikota and it was successfully tracked.

Simultaneously, an advanced cryogenic engine double the capacity with higher thrust is planned for the GSLV-Mk III launch by next year, Liquid Propulsion Systems Centre (LPSC) scientists said. The indigenous cryogenic engine to be used for GSLV Mark II on Sept 8 will be similar to the one used in GSLV-D5 launch two years back, the scientists said. Following that, ISRO is set to launch eight satellites on board PSLV C35 on Sept 28. It includes three Indian satellites led by ScatSat-1 for weather forecast and cyclone prediction.

ISRO’s scramjet on course

The Indian Space Research Organisation joined an elite club when, on Sunday, it successfully launched a rocket using a scramjet engine that was developed indigenously. This is ISRO’s first major step towards developing an air breathing propulsion system. The scramjet engine functioned for around six seconds. There are many reasons why the use of a scramjet engine is so attractive. A scramjet engine uses oxygen present in the atmospheric air to burn the hydrogen fuel. As a result, the amount of oxygen required to be carried on board would be reduced considerably as atmospheric oxygen is utilised to burn the fuel in the first stage. In general, propellant accounts for nearly 85 per cent of the weight of a rocket, and oxygen accounts for nearly 60 per cent of the weight of the propellant. Scramjet-powered rockets also have several times greater thrust compared with rockets powered by liquid fuel or even cryogenic fuel. Since about half of the propellant is required for the first stage to achieve the required velocity, a rocket using a scramjet engine would be significantly lighter and smaller and, therefore, cheaper. Alternatively, rockets fired by scramjet engines will be able to carry more payload.

Sunday’s test flight, which attained six times the speed of sound (Mach 6) and was able to achieve ignition and maintain stable combustion even at such high velocity for about six seconds, is a big technological achievement. This is akin to “lighting a matchstick in a hurricane condition and sustaining the flame” for six seconds. The air intake mechanism and fuel injection systems were also successfully demonstrated during the maiden test flight. Since it relies on oxygen present in the atmosphere, the trajectories of scramjet engine-powered rockets are vastly different from conventional ones — rockets with scramjet engines should remain in the atmosphere for a longer period than normal rockets. Typically, scramjet rockets climb to a certain altitude and remain in the atmosphere for as long as possible to achieve the required velocity. It will take many years before a commercial rocket powered by a scramjet engine takes to the sky as there are several challenges to be overcome. One challenge will be to test the engine at higher Mach speeds and prolong the period of combustion. Since the scramjet comes into play only when the rocket goes beyond Mach 5, an engine that initially works at subsonic speed (as a ramjet) and later as a scramjet has to be developed. But as in the case of the successful test flight of a reusable vehicle, the first experimental flight using a scramjet engine is a technological demonstration of ISRO’s capability and will go a long way in redefining its position as one of the leading space agencies in the world.

Remembering IRS-1B which was launched exactly 25 years back
Aug 29, 2016

IRS-1B, the second of the series of indigenously developed remote sensing satellites of India, was successfully launched into a polar sun-synchronous orbit on August 29, 1991 from the Soviet Cosmodrome at Baikonur. It carried a trio of Linear Imaging Self-Scanning (LISS) remote sensing instruments working in four spectral bands: 0.45-0.52 μm, 0.52-0.59 μm, 0.62-0.68 μm, and 0.77-0.86 μm. The 38.5 kg LISS-I images a swath of 148 km with a resolution of 72.5 mtr while the 80.5 kg LISS-IIA and LISS-IIB exhibited a narrower field-of-view (74 km swath) but were aligned to provide a composite 145 km swath with a 3 km overlap and a resolution of 36.25 mtr.

IRS-1B had improved features compared to IRS-1A like gyro referencing for better orientation sensing, time tagged commanding facility for more flexibility in camera operation and line count information for better data product generation.

IRS-1B, similar to IRS-1A with improved performance provided regular data to user community. The data from the satellite was used for various applications in the areas of integrated mission for sustainable development, agriculture, forestry, flood mapping, wasteland mapping, land use/land cover mapping, snow melts and run-off studies, urban sprawl studies, wheat production estimation, locating water source etc.

IRS-1B served for 12 years and 4 months and the Mission was completed on December 20, 2003. This satellite gave a confidence in the Indian Remote Sensing satellites and gave continued support to the Indian users, and slowly shifted the users from Landsat to IRS-1B.

Data sets of three seasons (Rabi, Kharif and Summer) have been archived as per the archival policy of ISRO. 64,939 LISS I scenes and 2,59,756 LISS II scenes have been archived during 1991 to 2001. 6,126 products of LISS-I data and 41,640 products of LISS-II data of IRS-1B have been disseminated to the various users earning a revenue of 14.5 Crores.

Even today, archived data is being used by academia for time series studies and these historical data are very much useful for legal studies which is new emerging applications.

25 years (some 2 years before launch of first PSLV rocket in September, 1993), we had to use a Russian Rocket for launching a satellite weighing less than 1 tonne.

And where have reached today? And where we will be by year end after launch of GSLV Mk3?

ISRO planning record 68 satellites’ launch next year

Indian Space Research Organisation (ISRO) is planning for the launch of a record 68 satellites in one mission by early next year.

“There are many launches. There is one particular launch we are planning about 68 satellites, that’s also there, that is yet to be finalised,” Antrix CMD Rakesh Sasibhushan told reporters in response to a question on the line up.

Antrix is the commercial arm of ISRO.

According to officials, if everything goes well, the launch may take place in another six to seven months and “the satellites will be nano in nature from foreign countries.”

Setting a record in its space programme, ISRO in June had successfully launched 20 satellites, including its earth observation Cartosat-2 series, in a single mission on board ISRO’s workhorse PSLV-C34 from the spaceport in Sriharkota, Andhra Pradesh.

The space agency had earlier sent 10 satellites into orbit in a single mission in 2008.

On concerns by certain sections in the US about ISRO launches as it is being subsidised by the government, Rakesh said “our competitiveness will give answer for this.”

“All launches are subsidised, it is not that we are subsidising or somebody else is subsidising. These government subsidies in the form of R&D investment comes in all launch programmes, now some private industries have come up who have started questioning, let them question,” he said.

“We have our own programme, we are competing with the world, we will try to be more competitive and probably that will provide the answer,” he added.

Rakesh said small satellites are going to become a large market and it can be exploited by Indian Industry.

“ISRO can play a technology providers role there. We would like to get this across to as many industries as possible to see that tomorrow the country is benefited by this.”

Space tech to offer crores for pvt sector soon

Indian space segment is looking at $16 billion market in next five years - an opportunity for the private industry to make hay while the sun shines

Antrix Corporation, the commercial arm of the Indian Space Research Organisation (ISRO), is providing a major push for the Indian private Industry to participate in the country's space programme in a big way to play a direct and active role in India's space segment, expected to touch $16 billion (about Rs 1.07 lakh crore) in the next five years.

Antrix Corporation chairman and managing director, S Rakesh, said globally the space market would cross $335 billion (about Rs 22.44 lakh crore) in the same period, during which all space agencies put together would totally launch a whopping 2,500 satellites.

Although no figure on how many satellites ISRO would launch in that period was disclosed, D Radhakrishnan, director (launch services & missions), Antrix Corporation, said in the early part of the next financial year alone (2017-18), ISRO is looking at launching a whopping 68 satellites. In June this year, ISRO set its own record of launching 20 satellites in just one launch using its warhorse polar satellite launch vehicle (PSLV) launcher from Sriharikota.

With the intensity of the space programme plans increasing, the endeavour would require the private Indian industry to play a major role, he said. "We see a large growth in the space segment in the future and want the industry to avail the space technologies developed by ISRO and come up with a clear-cut investment plan so they can come up in a big way," he said.In line with that, a three-day Bangalore Space Expo 2016, scheduled to begin on September 1, has been planned as a critical platform to provide the first major push for the Indian private industry to actively get involved in the country's space programme. "We hope this event would be a game-changer as far as the Indian private industry is concerned," said Rakesh. "The Bangalore Space Expo 2016 is an initiative to give a big push to the industry to ultimately be able to make satellite systems and mini-satellites."

He said the private industry could look at developing small satellite systems initially before gradually moving to manufacture larger satellite systems.

The Antrix Corporation CMD however said the road to such an involvement would not be easy and will not be accomplished overnight. The private industry would require at least Rs 20,000-30,000 crore ($2.98-4.48 billion) of total investment for the required infrastructure, facilities and services to be able to manufacture the first complete satellite before subsequently be able to make more.

NANO SATELLITE LAUNCHING


Radhakrishnan said they were looking at launching nano-satellites in the coming months.


Space scientists said the present trend was satellites becoming smaller with more systems and subsystems being packed into smaller areas. Sources have revealed that the delegation of Swiss space scientists who have arrived to familiarise itself with the Indian start-up atmosphere in the space technology segment, are set to discuss with ISRO the possibility of launching their own cube satellite, CubETH - which is as small as 10X10X10 cms and weighs less that 1 Kg - which aims at being the first nano-satellite to achieve precise orbit determination as well as altitude determination using signals of American GPS and Russian GLONASS constellation of global positioning system satellites. "Small satellites will be the large market," said Rakesh. "Therefore, we are getting across to the private industry to facilitate technology transfer to industry for building subsystems with minimum investments in partnership with ISRO."

GSLV FOR COMMERCIAL LAUNCHES?

Rakesh said they were looking for commercial launches for the Geostationary Satellite Launch Vehicle (GSLV), too, which has hitherto not happened as the Mark-III version of the launcher as well as a cryogenic engine to propel it was under development.


Now, with the cryogenic engine for the Mark-II version ready, Antrix Corporation is positioning itself to market the GSLV launchers for commercial launches of foreign satellites. The GSLV Mark-III's first developmental flight would carry the GSAT-19E, weighing 3.5 tonnes, but ultimately the launcher is being designed to carry payloads upwards of 4 tonnes, he said.

BANGALORE SPACE EXPO 2016

The 5th edition of Bangalore Space Expo would be held at Bangalore International Exhibition Centre from September 1-3 with the theme "Industry participation in space systems production, infrastructure creation and applications delivery".


The event will provide a platform for space start-ups and entrepreneurs entering into space market with innovative concepts like internet from space and moon exploration and will showcase their ideas, concepts and technologies at the event.
