ISRO General News and Updates

[Kshatriya87]

As of official news it's 20, though they could be launching two nano satellites with it.

If those 2 nano satellites you are talking about are the ones developed by Indian university students, then they are already counted in that number 20.

Hint to use ISRO data for monitoring

Pune: The Pune Municipal Corporation is consulting Space Application Centre, Indian Space Research Organisation, Ahmedabad, for using high resolution remote sensing picture data to keep a tab on encroachments and creating a 3D model of the city for estimating rooftop energy potential.

"With the CartoSat 2C being launched on Monday, the high resolution picture that the satellite can send back can be put to use to monitor any number of areas. The PMC has approached us to see the potential of using high resolution remote sensing data to monitor areas where encroachment is likely," said Gaurav Jain, scientist Space Application Centre at ISRO, on the sidelines of a symposium on 'Smart Cities and GeoICT Initiative' held in Symbiosis Institute of Geoinformatics on Saturday.

Jain said, "We will identify the building footprint of the city and calculate the integrated insulation data considering various parameters like weather, altitude, among others. Through this we will be able to understand how much solar energy can be converted into electricity which can be given back to the grid."

In ISRO's Record Space Launch, Google-Made Satellite Finds A Place

Story Highlights

• ISRO has scheduled a record-making 20-satellite launch from Sriharikota
• Among those is an earth imaging satellite made by a Google-owned company
• The launch also takes into orbit two satellites built by Indian students

New Delhi: In a first, Indian space agency ISRO is set to place into Earth's orbit a hi-tech satellite made by a Google company as part of a record-making 20-satellite launch scheduled for Wednesday from Sriharikota.

On its 36th launch, the Polar Satellite Launch Vehicle will fly 20 satellites into space at a cost about 10 times less than other space agencies.

As a mark of the India-US friendship, ISRO or the Indian Space Research Organisation will launch 13 American-made small satellites into space. This includes an earth imaging satellite made by Terra Bella, a Google-owned company. The 110 kg Google satellite called SkySat Gen- 2 is capable of taking sub-meter resolution images and high definition video.

In another possible first, an Indian start-up company Earth2Orbit has negotiated launch contracts with ISRO's commercial arm Antrix Corporation on behalf of foreign vendors.

On its 36th launch, the Polar Satellite Launch Vehicle will fly 20 satellites into space at a cost about 10 times less than other space agencies.

Launching 20 satellites in a single mission is like "allowing birds to fly in space", ISRO chairman Kiran Kumar told NDTV. "Each of these small objects that you are putting into space will carry out their own activity, which is independent of the other, and each of them will live a wonderful life for a finite period for which they have been designed," Dr Kumar said.

ISRO held the world record for the highest number of satellites to be successfully launched in a single mission after the PSLV placed 10 satellites in space on April 28, 2008. In 2013, an American Minotaur-1 rocket placed 29 satellites in one launch. The baton passed to Russia in 2014 when its DNEPR rocket placed 33 satellites in space.

The 320 tonne PSLV will carry 17 foreign small satellites from Canada, Indonesia, Germany and the US but the main passenger is a 727 kg Indian earth observation satellite called CartoSat, which can take images at sub-meter resolution.

The launch also takes into orbit two Indian academic community built satellites, Sathyabhamasat and Swayam.

What goes on behind such a complex launch? Dr Kumar calls it a "trick of the trade" and says tiny manoeuvres in the last stage ensure clean separation of these satellites.

With this launch, ISRO is ready to take on private billionaires like Elon Musk and Jeff Bezos who have entered the space launch business and offer far cheaper space launches.

Till now, ISRO has launched 57 satellites for foreign vendors from about 20 countries, earning about $ 100 million in the bargain.

Just few minutes, CartoSat 2C gonna be in space.
Launching CartoSat 2C is gonna be bigger deal than 20 Sat launch, given that it has a resolution of 0.65 metres. Can put our reconnaissance capabilities at par with United States, State of Israel and People's Republic of China.

A request to other members.
Though you can post launch pics, or tweets from ISRO's handle, please don't post basi mews from media again and again.
News from ISRO about successful launch is enough.
Instead post about huge
advantages of CartoSat-2C.

Let's leave ancient news of PSLV C-34.
ISRO is going to test a scramjet next month.
ISRO gears up to test scramjet engine

Flush with the success of the technology demonstration flight of its Reusable Launch Vehicle (RLV- TD) last month, ISRO is gearing up to test a scramjet engine based on air-breathing propulsion.

The test flight of the indigenously-developed scramjet engine is scheduled to take place from the Satish Dhawan Space Centre at Sriharikota sometime in July.

Named Advanced Technology Vehicle (ATV), the test platform will comprise a scramjet engine hitched to a two-stage sounding rocket (RH- 560).

“The vehicle has been characterised and is being fabricated at the VSSC and the ISRO Propulsion Complex, Mahendragiri,” VSSC Director K.Sivan told The Hindu over phone from Sriharikota, amid preparations for the launch of the PSLV-C34 carrying 20 satellites.

Coasting phase

The air-breathing engine will be released at a height of 70 km and ignited during the coasting phase. Apart from the hypersonic ignition at Mach 6, ISRO hopes to sustain the combustion for 5 seconds.

“The test is also expected to help us achieve good thrust value with the scramjet engine,” Dr. Sivan said.

Maintaining combustion in hypersonic conditions poses technical challenges because the fuel has to be ignited within milliseconds.

Space agencies across the world are focussing on the development of scramjet technology because it contributes to smaller launch vehicles with more payload capacity and promises cheaper access to outer space.

Atmospheric oxygen

While conventional rocket engines need to carry both fuel and oxidiser on board for combustion to produce thrust, scramjets obtain oxygen from the atmosphere by compressing the incoming air before combustion at hypersonic speed. The scramjet engine can also liquefy the oxygen and store it on board.

Dr. Sivan said the post-flight analysis of the RLV-TD test flight had shown encouraging results.

Critical technology

“We could understand the hypersonic aerothermodynamics of the delta winged body, the Thermal Protection System worked well and the hypersonic re-entry and autonomous navigation and landing could be validated. Another critical technology that was successfully tested was the Flush Air Data System to measure the surface pressure on the aircraft.”

He said it would take more analysis and detailed discussions and planning to move on to the development of the full-scale version of the RLV.
