A First Look at 162173 Ryugu and 101955 Bennu: Hayabusa 2 and OSIRIS-REx Arrive at Their Respective Target Asteroids III Posters


Submit an Abstract to this Session


Session ID#: 44067

Session Description:
Both the Hayabusa 2 and OSIRIS-REx spacecrafts begin proximity operations in June 2018 and October 2018 respectively. This session presents first results from their target asteroids 162173 Ryugu and 101955 Bennu.  Global imaging, geochemical and geophysical analyses of these two primitive B-type asteroids reveal exciting new discoveries into the origin and evolution of these two asteroids.

We performed crater size-frequency measurement on Ryugu using high-resolution images obtained by Hayabusa2. Using Ryugu cratering chronology model, the surface age of Ryugu was estimated to be 0.1 to 1 billion years from the density of craters larger than 100 m in diameter. (416730)
