Yep this is true, the moment he became chairman , he pushed for Gaganyaan, he gave a hint the day he was announced as the chairman. His predecessor Dr. A S Kiran Kumar didn't give much importance to the Human Space Flight Program
Kiran Kumar had put human spaceflight on hold, not just ignored it. That's why Sivan was brought.

Vintage ASLV launch pad. This launch pad is decommissioned, but it still exist there, I wonder whether it is possible to modify it and refurbish it to launch Agnikul Cosmos and Skyroot Aerospace's rockets. This launch pad is exactly similar to the First Launch Pad, but smaller

Wasn't there plan for new launch pad in TN? Gareeb scientist has done a video on it, reasoning was that since the rockets which are launched from SHAR they have to burn extra fuel to manoeuvre in such a way to avoid flowing over sri lanka which can be avoided if it launched from TN and it specially helps with small rockets like SSLV, rockets like Vikram 1 etc. from private players.

Also, since we are talking about vintage images, here's one. I don't know what happened isro's website is a bit bricked so when you look up some images in their media section you can't view them (At most you can view the low-res thumbnail which is useless) so i had to look up the page in archive.org and here's a great close up pic of RLV.
I haven't seen most of the pics in public sphere that much so sharing here.

Last one is the most common pic that you can find

That new launch site in TN will take time, SSLV and other small LVs will be launched from both Sriharikota and TN depending on the mission requirements. For Sriharikota , if possible they can use ASLV launch complex instead of building an entirely new LP.

waaaw, never saw those, nice pics.

which tiles are we using for reentry??

Its windward side which will face the highest temperature is made up of silica tiles and some other parts like elevons are made up of titanium though overall body is made up of aluminum. I already shared it in previous comment iirc but this article by DDR provides a good detailed information on rlv https://delhidefencereview.com/2020...os-reusable-launch-vehicle-technology-part-i/

The max altitude it reached was around 65km and peak speed of 5 mach.

From isro's website :

Source : https://www.isro.gov.in/launcher/rlv-td

I was looking for more details, flipping through archives and presentation to get more understanding of HLV, sce-200 engines since i was getting uneasy with the leaps that likes of SpaceX were making so found rlv that way and realised that ISRO has videos of it on youtube which were not bad since if you look up the video they even had the separation video kek.

Another interesting mission which i think people don't talk about much is CARE on iirc GSLV mk3 first launch? Apart from the testing of crew escape system. There are some great clips and images if you try looking them up.

I had the original ppt bookmarked but it will take a bit of time to fetch it since i am not able to find it currently.

when do you think this shuttle will be ready
Long way to go honestly, it's just TD for now. Next thing we are trying LEX and then Rentry and landing. There's a good post from u/ohsin on r/isro.
From a presentation in 2019, there's a mention of two engines and maybe from 3 engines for RLV. It sort of reminds me of something like x-37b with same wingspan and a bit higher volume and size.

I have no source any particular sort of launch of sats from this but the possibility of something like this to launch nano-sats? Maybe? But is it feasible or cheaper than alternative? Remains to be seen.

Here's on interesting pic i got was rlv-td mounted on what seems to be GSLV mk2, probably for testing.


Also, we really need a name for rlv-td, i hate using the term space shuttle.

i thought that it will be used as transportation of crew, and other logistics, maybe a robotic arm :shock: lilke in iss, this might seem too good to be true, but I read somewhere that this rlv-td is 1/6th of orignal.
so orignal one will be very big.

Crew ? No but maybe small sats maybe?

>size
To provide context, shuttle is almost double the dia and almost 4x the height of the TD. It's a good start.

But considering how shuttle was a mixed bag I wonder what's the future that TD holds though many issues that plagued shuttle were including the lack of autonomous flying along with too much of a blunt shape while TD is more like Starship (curvature) since the main part of the TD is cylindrical.

TD is just that: a TD. Its not meant to do anything more than be a testbed for technology required for the real RLV which will enter design phase after TD work is done. The actual RLV is meant to take 11 tons payload to LEO. Its own weight will be around 6 tons, so that requires 17 tons to LEO capacity as lower stages. Will not mounted on a GSLV Mk2, that graphic from 2019 is outdated. Instead it will be mounted on an SC-400 stage and a C-32 stage. Would make for a great supply vehicle for our space station. But yeah, no crew.

Do we have any official info on this ⬇
Does anyone know what is the maximum sustained acceleration of human rated gslv mkiii given that gslv mkiii first stage is solid, hence can't be modulated ? (Nasa has a requirement of max 3g limit on sustained acceleration)
