1967: Explorer 35 - USA Lunar Orbiter launched. Orbiter acquired field and particle data. It continued until 1972.
1969: Apollo 11 - USA Lunar Manned Lander (July 16-24, 1969) Crew: Neil A. Armstrong, Edwin E. Aldrin, Jr., Michael Collins. Apollo 11 was the first manned lunar landing, which took place on July 20, 1969.

1994: Hubble Space Telescope - USA & Europe Telescope photographed the collision of Comet Shoemaker-Levy 9 with Jupiter.
1999: Deep Space 1 (DS1) - USA Asteroid and Comet Flyby - (launched 24 October 1998) flew by the Mars-crossing near-Earth asteroid 9969 Braille. The Deep Space 1 (DS1) is the first of a series of technology demonstration probes being developed by NASA's New Millennium Program. It again flew by comet Borrelly in September 2001.
