Ten Years, 3.98 Billion Miles
The Rosetta satellite and its probe payload arrived at the Comet 67P/Churyumov-Gerasimenko Aug. 6 after 10 years, five months, and four days in space. Rosetta traveled 6.4 billion kilometers (3.98 billion miles) on its journey and orbited the sun five times.
The distance 510 million kilometers (317 million miles) between the comet and Earth means the ESA did not know for 28 minutes and 20 seconds whether or not the landing was successful.
Apparently the anchors that were supposed to fire and embed themselves in the comet did not fire so engineers are working on what to do about that but still, What. An. Amazing. Feat.
