Re: Indian Space Program: News & Discussion - Sept 2016

Found a JPL document which defines acceleration required for various lunar transfers i.e. defined by them as low energy vs high energy direct transfers. Will take some time to go through it and understand it and then translate energy requirements into corresponding payload/mass for a given booster s...

The Chandraayan 2 mission orbiter and lander is about 3800 kg? I presume that ISRO is us...

As tsarkar says, what is critical is what altitude the F-16s were when they fired their AMRAAMs vs the SU-30 altitude. From what I remember from the IAF briefing, at least one group of F-16s was at 40,000 feet and went supersonic. At that altitude and speed the AMRAAM would be able to have an effect...
