ISRO RLV-LEX autonomous landing mission

[VkdIndian]

Well its great to see India toying with a 60 year old technology which after almost 10 years of development is barely 1/20th the size of an actual space shuttle. It still cant fly or navigate. It took them 7 years, yes 7 years to complete this experiment after the first HEX experiment in 2016.

It is correct that India is way behind in many leading technologies. Should they stop trying because they are behind the world leaders?

ISRO has enough expertise to decide the best path towards reusable technology. The one used by SpaceX or now abandoned US Space shuttle program. No need to start calling them fools.

Things move slowly in India. It is a known problem and government has done a lot of work to shrink the timelines. Availability of money remains the biggest constraint. What to do. We are still a poor nation.

No need to thump chest but no need to go into mourning like you either.

It is a milestone and would remain so.

There is no point in explaining things here, when someone is trying to shit on things, they will do it one way or another.

What pilot? It is autonomous landing...

I know. Tell that to

Vikramaditya-I​

it's an AUTONOMOUS landing. It did it by itself, not with a drone pilot remotely piloting it

I know tell that to

US does seem to have ditched/retired the manned shuttle and have been using soyuz? and ESA for manned rocket and reentry to and from the ISS, right ?

wrong, ESA doesn't do manned space flights.And the US hasn't used Soyuz for a long time. The greatest challenge in building a reliable reusable reentry vehicle isn't landing the thing, it is to make sure the vehicle survives reentry. The only reason the US is pursuing vertical landing is because there is no runway on the moon or Mars. Even if there was one, with the approach speeds that the vehicle will hit on Mars we will need a runway 100 miles long and tires made of adamantium.

Why no parachute into Mars ?

also, how are Astro and Cosmo nauts traveling between earth and the ISS then ? oO

India is on the rise in all directions..great achievement and congratulations to indian scientific community..being underdeveloped in some areas should not be an excuse not to shoot for the stars.

parachutes aren't effective in thin Martian atmosphere less than 1% volume of Earth.
How do Astronauts get to ISS? A giant trampoline.

Russian space agency chief Dmitry Rogozin once ridiculed the lack of a U.S. manned flight programme, saying it might as well "deliver its astronauts to the ISS by using a trampoline".

Europe’s Mars lander parachute problems may be worse than thought

ESA has yet to conduct a successful test of the parachutes at supersonic speeds.

maybe rocket booster bursts to aid both maneuvering and deceleration ?

I had the same question, that it was accelerating at a fast pace and how it would land at that speed. I was amazed that it landed in one piece. lol.

The tailess design might be the reason & manuvering at the end of the runway does suggest that it needs a better breaking mechanism. None the less it's great thing to have. Usefulness of automated landings for RLVs maybe debatable but it will benefit india in it's drone programs where a drone operator losses comms for whatever reasons & drone makes an automated landing.
