Athena was a proposed space mission that would have performed a single flyby of asteroid 2 Pallas, the third largest asteroid in the Solar System.[1]
If Athena had been funded, it was planned to share the launch vehicle with the Psyche and Janus spacecraft and fly its own trajectory for a Mars gravity assist to slingshot into the asteroid belt. It would have taken about two years to reach Pallas.[1] The mission's principal investigator was Joseph O'Rourke, at Arizona State University.
The Athena spacecraft was examined in Category 1 of the 2018 NASA SIMPLEx competition and was eliminated before reaching Category 2; it will possibly be proposed at a later unknown time.[2] The Athena mission was beaten by other mission concepts such as the TransOrbital TrailBlazer lunar orbiter.[3]
