India Space Agency

For SpaceNut .... there were 7 topics containing the word India or Indian, but they were all written with specific focus.

This topic is offered for generic updates on activities of the India space program.

India is doing a wide range of missions, and we have topics about some of them already.

This topic is offered for NewMars members who are looking for a topic that will fit most any news that shows up in the feeds...

ChatGPT (the original pre-2021 version) reported this today:

Hello again ... i understand your database is closed at 2021 - please find the address for the indian space agency, suitable for air mail
Certainly, I'd be happy to help you with that! The address for the Indian Space Research Organization (ISRO) that you can use for air mail is:

Indian Space Research Organization (ISRO)
Department of Space (DOS)
Government of India
Antariksh Bhavan, New BEL Road
Bengaluru - 560231

Re: India Space Agency

Some news I seen from Hindu India news bloggers was saying the budget was going to be cut by 9% while others said new missions were upcoming

India tests recovery of spacecraft for Gaganyaan astronaut mission (photos)

Recovery procedures are yet to be finalized, ISRO said.

Roscosmos is studying the possibility of supplying ten RD-191 rocket engines to India in the period from 2024 to 2029, said Valery Sherin, Deputy Director General of Roscosmos.

Re: India Space Agency

Indian Manned Spacecraft

http://www.astronautix.com/i/indianmann … craft.html

As of 2015 the design utilized a Soyuz-shaped reentry capsule with a mass of 3735 kg, a diameter of 3.100 m and height of 2.678 m. The ablative reentry shield consisted of carbon phenolic tiles, with tan medium density ablative tiles covering the rest of the outer surface. After re-entry, at a velocity of 233 m/s, a pair of 2.3 meter diameter pilot parachutes stabilized the capsule. This was followed by a pair of 6.2 m diameter drogue parachutes, which reduced the velocity to 50 m/s. At 5 km altitude three 31-m diameter main parachutes deployed. The capsule was designed to splash down in the ocean followed by recovery by Indian naval vessels. The reaction control system consisted of six 100-N thrusters burning MMH / MON3 storable propellants. The capsule was designed to initially accomodate two astronauts on long-duration solo missions. The design allowed later modification to carry three on short-duration shuttle missions to an orbiting space station.

In comparison with the Soyuz and Shenzhou capsules, the Indian version is significantly larger and heavier:

Re-entry Vehicle   
Total Mass-kg                3,000     3,240     3,735
Length-m                      1.90      2.06      2.68
Diameter-m                    2.17      2.52      3.10
Volume compared to Soyuz      1.00      1.46      2.88

The service module, based on a 2013 ISRO drawing, is powered by two high-expansion-ratio liquid propellant engines. Based on the payload capability of the GSLV-III booster, it would have a mass of around 3000 kg. A launch escape system. using a tower approach like that on Soyuz, Shenzhou, and Apollo, was planned. In-cabin space suits would be based on the Russian Sokol suit.

Re: India Space Agency

The article at the link below reports on a first landing of a prototype space plane ...

https://www.space.com/india-space-plane … st-success

India successfully lands reusable space plane prototype for 1st time (video)

By Sharmila Kuthunur published 7 days ago

India is working to become a member of the space plane club.

India has for the first time autonomously landed its reusable space plane prototype, marking a major milestone in the country's pursuit of low-cost access to space.

On Sunday (April 2), the Indian Space Research Organisation (ISRO), India’s national space agency, announced that it had completed the second of four experiments designed to get its robotic Reusable Launch Vehicle (RLV) space-ready.

The latest experiment — Reusable Launch Vehicle Autonomous Landing Mission (RLV LEX) — was carried out in a test facility owned by the country’s Defence Research and Development Organisation (DRDO) in Karnataka, a state in southern India. As part of the mission, the 21-foot-long (6.5 meters) space plane was airlifted by a Chinook helicopter, flown by the Indian Air Force, to an altitude of 2.8 miles (4.5 kilometers) and released mid-air at 7:10 am local Indian time (0140 GMT; 9:40 pm EST on April 1).

Then, the space plane, a miniature vehicle that is still being developed, demonstrated its ability to perform a series of approach and landing maneuvers that helped it touch down safely 30 minutes later, at 7:40 am local time in India (0210 GMT; 10:10 pm EST on April 1) on the runway operated by the same test facility.

Re: India Space Agency

For Mars_B4_Moon ....  Tnanks for Post #16, with news of the next moon landing attempt...

Reporters occasionally become confused, and editors are supposed to find obvious errors....

NewMars members may be able to spot an error in this quote...

Chandrayaan 2, which was planned to demonstrate soft landing and roving, crash landed 2.1 km from the surface of the moon.

Re: India Space Agency

Errors like that are fairly-often committed by reporters who know little-to-nothing about what they are reporting.

I don't know the details of that landing failure,  but I'd hazard the guess it SHOULD have read somethin like "crash landed from 2.1 km above the surface of the moon".

There is spell check and sometimes grammar check (which I find particularly objectionable),  but there is NO SUCH THING as content factuality check!  He who writes it has to do that,  himself.  Or herself.

Re: India Space Agency

There is another possibility .... In the past, when printing was done with lead slugs, reporters were instructed to write the most important details at the beginning of an article, and less important details at the end.  If the paper ran out of room, the editor would cut from the bottom, to fit the article into available space.

That should no longer be necessary, but if it still happens, then an editor might try to save space by cutting words out of the text submitted by the reporter.

In the current age, I expect there ** is ** no editor for online publications.  If there had been one in this case, then that person might have caught the factual error.

In the end, it is up to the reader to detect faulty writing. 

Since this is the India Space Agency topic, I'll add a note that the launch/mission planners have (apparently) added sensors in an effort to try to prevent the error from repeating at the next try.

Re: India Space Agency

It used to be part of journalism for the reporter and the editor to "get it right".  And to recognize when they needed to consult an expert,  because most members of the public cannot.

Re: India Space Agency

I probably should have read the article instead of scanning through it quick and posting a link. I still believe some news is worthy even if they are not wrote by science people. India news is interesting but from my experience India Hindu news is notorious for throwing in nonsense such as Mystic Voodoo Religious Astrology stuff into a 'Science' article so don't be shocked to see stuff which doesn't really make sense in an article. Journalism is getting stranger these days, they might also be using Chatbots and AI to help them quickly write articles.

I will take a quote from the article

The site was selected as it has several craters that remain permanently in shadows, increasing the chances of examining water ice.

If this report is true then we have Lots of nations looking at the same small regions thought to contain possible water ice.

On the previous Chandrayaan-2
An archive report on times of Times-of-India website with a picture illustration says it suffered a malfunction glitch and 'deviated from its intended trajectory starting at 2km or maybe '2.1 km (1.3 mi) altitude' reported on other sites

Re: India Space Agency

For Mars_B4_Moon ... re failure of Chandrayaan-2 ...

On the assumption you can't possibly read everything that comes out about a topic, here is a note I made recently, while reading about that flight failure ... I think the information is actually posted here in the forum.   The report was to the effect that the flight planners did not anticipate the drop off of elevation readings as the vehicle crossed over the rim of the destination crater, and (I'm working from vague memory here) the improperly programmed software could not handle the unexpected input, and began firing for a landing long before it was appropriate.

The "Extra brake thrust" would have been the landing sequence performed early.

The world's most populous nation has a comparatively low-budget aerospace programme that is rapidly closing in on the milestones set by global space powers. Only Russia, the United States and China have previously achieved a controlled landing on the lunar surface.
