Re: Indian Space Programme Discussion
Ion thrusters lsp is slow but steady a spring gives one shot and that's it.ion thrusters are to fire for much longer time and that is how they can theoretically reach stupendous velocities but not rapidly but over a very vetylong time

Re: Indian Space Programme Discussion
One of Buzz Aldrin's seminal papers in MIT was to establish the method for orbital rendezvous. If you impart velocity to an object in orbit it will not approach another body but will instead obtain a higher orbit. The reverse occurs during slowing. That us why for orbital rendezvous if you want to ...

It was spotted floating and did not disintegrate. It would have sunk after some time. They did not expect the structure to survive after landing as the planned Landing was targeted 5 meters above the water. They may ahve tried to recover it for all you know but that was not planned.

^Optimization is a big thing and requires a lot of work. They would have run quite a few simulations. One thing is it is not just about optimization wrt payload etc but also costs for eg full composite casing would be more efficient but the cost of this would be very high offsetting the advantage.

In fact full validation of the tiles at peak reentry was done with SRE1 rather than CARE which was an atmospheric test. SRE1 entered from above the Karmann line and splashed down facing the full brunt of reentry.

Re: Indian Space Programme Discussion
There are different methods of analysis of the thermal insulation on reentry. The most important thing is the temperature within the capsule or plane so that is what needs to be analyzed. We already have the tile wear data with SRE1 and CARE. Also the heat shield is ablative so certain portions are ...
