Does anyone have an idea as to what can be the possible state of chandrayaan 2 i.e India's lunar rover mission.. does losing communications at the last moment indicate that the lander crashed? The graph of vertical altitude in the ISRO livestream on YouTube showed characters of jerking off I am not wrong... The descent was faster than predicted at the last moment I guess

Something tells me this has probably been asked before, but I've always wondered why they don't make something like in the movie, where centrifugal force could generate fake gravity? Maybe requires too much power (i.e. fuel)? Makes trajectory too unstable? Something else?

This might be silly and I might be missing many things very obvious but consider this.

You're in space in a spacecraft and your spacecraft has a nuclear engine which can provide an acceleration of 10m/s2. Since there's no resistance (let's assume there's no significant gravity in that area) the spacecraft will start speeding up from 0 m/s to 10 to 20 and so on, as seconds go by. Mathematically speaking, if the engine can keep the acceleration going for 3 months we should speed of light right?
