2019 09/03 インドのVikram軟着陸機が月面からの高度120km円軌道から離脱し、月面からより低高度近月点を持つ長楕円軌道への第１回のde-orbitingマヌーバが成功したようです。明日の早朝により第2回de-orbitingマヌーバでさらに低高度近月点を持つ長楕円軌道になる予定です。いよいよ一番難しい軟着陸局面に入ります。緊張ぶりは以下の管制室の写真にも現れています。

The first de-orbiting maneuver for Chandrayaan-2 spacecraft was performed successfully today (September 03, 2019) beginning at 0850 hrs IST as planned, using the onboard propulsion system. The duration of the maneuver was 4 seconds.
The orbit of Vikram Lander is 104 km x 128 km. Chandrayaan-2 Orbiter continues to orbit the Moon in the existing orbit and both the Orbiter and Lander are healthy.
The next de-orbiting maneuver is scheduled on September 04, 2019 between 0330 - 0430 hrs IST.
