Comet 67P/Churyumov-Gerasimenko by Rosetta’s OSIRIS narrow-angle camera on 3 August from a distance of 285 km. The image resolution is 5.3 m... 現在は彗星の表面から約100km離れ場所を飛んでおり、また彗星の周囲を回る軌道に入っている。今後、高度は最大50kmまで接近する予定で、また30kmにまで下げることも試みるとしている。
Only 15 minutes after its closest approach to Pluto on July 14, 2015, NASA’s New Horizons spacecraft looked back toward the sun and captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto’s horizon.
