A Gemini class manned spacecraft?
4,000 kilos was about the mass of the Gemini
two-seater spacecraft.
Should India pursue manned spaceflight projects
or more ambitious unmanned deepspace projects?
My opinion is that India should pursue more ambitious
unmanned deepspace missions, after their Lunar
orbiter project achieves success.
There are 1,000's of asteroids waiting to be visited,
and they are easier to visit by spacecraft [manned or unmanned]
than to orbit our Moon.
