ファルコン9ロケット、再び洋上着陸成功!~これまでの着陸との違いとその意義~
Blazing towards the ocean, the booster uses the grid fins to modify its angle of attack & control the downrange travel distance. #Falcon9
2016-05-06 14:28:45This mission uses a three-engine landing burn, cutting gravity losses but also eliminating any last-second margins. bit.ly/1Od1EFe
2016-05-06 14:29:03今回はエネルギーが大きい静止トランスファ軌道への投入のため推進剤の余裕が少なく、これまで回収に成功した時と違い、着陸直前に1基ではなく3基のエンジンで一気に減速しそのまま着陸する、という離れ業が要求されます。
はたして…。
Woohoo!! twitter.com/spacex/status/…

2016-05-06 14:32:15まさか、難しいほぼ弾道飛行になってしまうGTOミッションでの着陸にも 2回目の挑戦で成功してしまった!!!うわこれすげえ…。 pic.twitter.com/dOZO5V3pUu
2016-05-06 14:34:41第1段、GTOミッションでの挑戦2回目にして、洋上着陸プラットフォームの中心に着陸!素晴らしい快挙!
あとは衛星の打ち上げが成功するか…。
(本来こっちが重要なのですが。)
During the 18min coast, the stack will continue to the south-east so that the second burn can center the equator. bit.ly/1Od1EFe
2016-05-06 14:33:02The second MVac burn is expected to start at T+26:27 and last under one minute to significantly raise the apogee. #Falcon9
2016-05-06 14:36:15Second stage and JCSAT-14 now in coast phase. Webcast returns in about 10 minutes for second stage engine restart and satellite deploy
2016-05-06 14:35:36The #Falcon9 second stage is coasting before critical restart to deploy JCSAT 14 satellite. spaceflightnow.com/2016/05/05/fal… pic.twitter.com/fi3rPYET1g
2016-05-06 14:35:50While coasting, the second stage of #Falcon9 uses its attitude control system to fly a pre-programmed profile & re-orient for the burn.
