TopicsHayabusa2 Provisional Mission Schedule

Hayabusa2 mission schedule: provisional version (as of June 7, 2018).

The current schedule for Hayabusa2 is shown below. The dates here are all provisional (unless marked "finished") as operation timings are very susceptible to change due to a wide range of factors, including our knowledge about Ryugu expanding as we approach the asteroid.

We will update the table below whenever changes are made.
