The current schedule for Hayabusa2 is shown below. The dates here are all provisional (unless marked "Complete") 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.
