[TD1-R1-A] As if refusing to let us land, Ryugu's surface is covered with boulders. To reach this unexplored place, we have to use all our power to develop asteroid descent techniques. (Tweets are currently by project member, "IES 兄"; the big bro of the Ion Engine System!)

[TD1-R1-A] Preparation included
・Repeated real time operation training before arrival
・Landing sites sel ected by both engineers & scientists to max safety & results
・Simulations of guidance control & onboard checks
This allowed spacecraft control to within 10m at altitude 50m!

[TD1-R1-A] The purpose of this descent is to check the navigation accuracy at an altitude below 50m. For touchdown, it is necessary to understand the operation characteristics of the LRF (Laser Range Finder) which is responsible for the altitude measurement at close range.

[TD1-R1-A] As MINERVA-II1 and @MASCOT2018 headed down to the asteroid nearly one after the other, they gave sequential data fr om the surface of Ryugu. This is very important information for touchdown.

[TD1-R1-A] The Project is aiming for a more secure & safe touchdown operation by using all possible available information. Currently, the altitude is just below 279m. We hope to convert the shouts from all around the world into the power for a successful operation today! (IES兄)

[TD1-R1-A] The target site at this time is "L-08" (where the red line was extending) and we aim to be around 70 - 80m from the equator in the northern hemisphere.

[TD1-R1-A] This rehearsal also successfully tested the altitude range measurement from the LRF.
・Lowest altitude arrival time: October 15 at 22:44 JST.
・Lowest altitude: 22.3 m (altitude calculated from the LRF range measurement)
The current height of the spacecraft is 1.8km.

★ Hayabusa2 status (the week of 2018.10.01) ★

Preparation for the MASCOT separation operation began on September 30 and descent began around noon JST on October 2. On October 3 at 10:57:20 JST, MASCOT was deployed at an altitude of 51m. MASCOT then landed on the surface of Ryugu and proceeded to operate for about 17 hours. The spacecraft then returned to the home position after staying for about 1 day at an altitude of around 3km. Originally, we planned to reach the home position on October 5, but due to the forecast of a typhoon approaching Japan at the weekend, this was delayed until October 8.

★ Hayabusa2 status (the week of 2018.10.08 ) ★

On October 8, the spacecraft returned to the home position at remained there for this week. Project members made the final preparations for the second touchdown rehearsal (TD1-R1-A). Images taken by MASCOT were released by the MASCOT team and the surface conditions of Ryugu were even more apparent. From October 14, the TD1-R1-A operation began.

★ Hayabusa2 status (the week of 2018.10.15) ★

At midnight on October 15 during the TD1-R1-A operation, the spacecraft reached an altitude of about 20m from the asteroid surface and then rose to return to the home position. With this operation, we were able to confirm the performance of the LRF (Laser Ranger Finder), which is a laser sensor for close range, and were also able to acquire more images of the surface of the asteroid. We are now busy analyzing the data from TD1-R1-A and confirming the procedure again for the next touchdown rehearsal (TD1-R3) in the next week.
