1968 is a long time ago - so how come, with all the massive computer advances since then, have we not done anything as remotely exciting as putting a man on the moon, since?

Also - had we moved with the same progression, should we have put a man on Mars by now?

Find speed of a satellite which orbits the moon near moon's surface?What is the kinetic energy per unit mass of the satellite?
My workings are Fc(centripetal force)=Fg(gravitational force) so v=(GM/r)^(0.5)= 1680 m/s I got this correct but I took kinetic energy per unit mass of the satellite equals to gravitational field strength which is X=(GM/r) = 2.42x10^6 is my thinking correct? but the answer is 1.41x10^6J/kg.
Details given are radius of moon=1.74x10^6 m and mass of the moon=7.35x10^22 kg

Another extra unrelated question is that if the assumption is that gravitational potential at the surface of the earth to be zero, can we use the equation F=GMm/(r)^2?? Whats the meaning of the assumption? we use Energy=mgh instead??? Eg to find the gravitational field strength at p what do we do?????????
