speaking of realistic, i"d like to see Kerbals follow a similar mission flow to that of NASA, ie start out with reaching space height, then a full orbit, etc. But as it is now, you have to send up a MANNED mission first, because you don't get any remote guidance devices at the first tier. you know, to test your rockets are safe enough for a Kerbal. Also, we get a transmitter, but no power modules (solar or nuclear). therefore i've never had enough power to transmit the data back.
