1973 was a busy year for NASA with five launches. Skylab 3 and 4 were both launched in 1973 as well as Pioneer 11, Explorer 49, and Mariner 10. The Skylab 3 crew of Alan Bean, Owen Garriott and Jack Lousman saw what they believed was a red glowing satellite roughly 30 to 50 nautical miles from Skylab and the satellite mirrored their orbit for approximately 10 minutes. As of today that satellite still has not been identified. Skylab 4 launched late in the year and would be the last of the Apollo Skylab missions. Pioneer 11 left Earth with the purpose of studying Jupiter and Saturn. The craft reached the two planets later in the year and then just kept going into deep space. NASA finally lost communication with Pioneer 11 in 1995. Explorer 49 was a Radio Telescope sent to orbit the moon and study deep space. It was the last America Lunar mission until 1994. Mariner 10 was sent to study Venus and Mercury. Mariner 10 used the gravity of Venus to curl it into a flight path to Mercury. It subsequently used the suns gravity and it own momentum to put it in an orbit around the sun that would ultimately give three close passes to Mercury before its fuel for the stabilizing rockets would run out.
