[SCI] April 4 at 23:47 JST: it was confirmed that the spacecraft descent rate has slowed as planned. We therefore performed the GATE 2 check and confirmed that there are no issues. Continuation of the operation was decided as "GO" at 23:55 JST [GATE 2 continue operation: GO].

[SCI] First image is the navigation image received on April 5, 04:35 JST. The target area of the SCI is visible and this is enlarged & accentuated in the second image on the left, with previously taken data on the right. We are aiming for this area.

[SCI] April 5, 07:00 (JST): operation has changed from the night shift to the day shift. The Small Carry-on Impactor (SCI) will be activated during this shift. At 08:09 JST, the spacecraft had descended to about 1.5 km.

[SCI] During the use of the SCI, communication was planned via Usuda station. But there is a possibility that Usuda cannot be operated due to strong winds. We've therefore switched to the planned backup station in Canberra. During critical operations, the backup station is vital!

L12 is the region H2 is descending over. L12-S01 is the candidate location for the next touchdown and roughly where the SCI is meant to hit

SCI detonation should now have occurred and been detected by DCAM3. Now if DCAM3 relays the data back to H2 right away, we should get confirmation at about 0253 UTC, another 10 min
