re: Yes, but
There's nothing wrong with downsizing during 'slow times'. As for manned missions, nothing as big as Apollo has come up. Mars is farther away than the moon, so robotics (incl. scopes) are taking their turn in the 'limelight' (albeit a long 30+ years to look for life, etc.). Manned space exploration is going to stay with us for a long time and so will NASA.
