Athena I | Starshine-OSCAR-43

Research (Atmospheric density) satellite built by Naval Research Laboratory (NRL) for NASA, USA.

The Athena I, known as the Lockheed Launch Vehicle (LLV) at the time of its first flight and Lockheed Martin Launch Vehicle (LMLV) at the time of its second flight, is an American small expendable launch system which was used for four launches between 1995 and 2001. It is a member of the Athena family of rockets, along with the larger Athena II.

Lockheed Martin's Space Division started in the production of missiles and later ICBM's in the 1950s. Their TITAN missile system was used for 12 Gemini spacecraft and the Voyager probes. They have worked largely in collaboration with NASA on many of their probes, landers, and spacecraft, and hope to play a key role in NASA's return to the moon in 2024.
