A Close Encounter with Binary Asteroids
University of Colorado, Boulder | 2020 Sep 10
These bodies are pairs of asteroids that orbit around each other in space, much like the Earth and moon. In a project review on Sept. 3, NASA gave the official go-ahead to the Janus mission, named after the two-faced Roman god. The mission will study these asteroid couplets in never-before-seen detail.
It will be a moment for twos: In 2022, the Janus team will launch two identical spacecraft that will travel millions of miles to individually fly close to two pair of binary asteroids (1996 FG3, 1991 VH). Their observations could open up a new window into how these diverse bodies evolve and even burst apart over time, said Daniel Scheeres, the principal investigator for Janus.
