ロゼッタ計画の責任者、フレッド・ヤンセンは67P、別名チュリュモフ・ゲラシメンコ彗星に、2014年見事に探査機を着陸させました。驚嘆と笑いに満ちたヤンセン氏の話のなかで、彼は着陸機「フィラエ」を地球から５億km離れた彗星に下ろすために行った複雑な計算について触れています。また、そこに至るまでに撮影された、見事な写真も披露しています。

彗星に着陸する方法とは

Guiding a spacecraft to orbit and land on a comet transformed what humanity knows about the solar system’s beginnings. The Rosetta mission traveled 500 million kilometers and achieved several historic firsts, including landing a probe on a moving comet. Stunning discoveries followed: the comet holds ancient material and would float in water due to its low density, and erupts with 100 million kilos of gas and dust per day near the sun. These revelations help unlock the cosmic puzzle of how water and organic molecules arrived on Earth.
