Many of NASAs latest successes have been unmanned space probes.

APOLLO

This is the big one. This is the project that took humans to the Moon. The Apollo project had missions that went from 1966 to 1972. There were eleven missions with humans aboard. Six of those missions landed on the Moon. There was a smaller sub project called Apollo-Soyuz that began in 1975. This was a joint effort with Russia and it was designed to test the compatibility of U.S. and Soviet space vehicles.

SKYLAB

Skylab was one of the first research ships that orbited the Earth. It stayed in orbit for 171 days and then fell to Earth in July of 1979. The United States used Skylab to test the effects of a long duration space mission. NASA wanted to provide humans a living and working area in an orbiting scientific lab. While scientists worked, their job was to expand the field of astronomy and conduct experiments.
