Remember how exciting it was when the Rosetta spacecraft began orbiting Comet 67P/Churyumov–Gerasimenko in August of 2014? The mission has been so fantastic and has revealed this comet in such magnificent detail, and yet it was a bit of a let-down when the Philae comet lander got lost after its initial landing thud on the comet’s surface. The lander apparently bounced in the comet’s low gravity to … well, no one knew where. But now less than a month before the end of the mission, Rosetta – still in orbit – has revealed the Philae lander wedged into a dark crack on the comet.
ESA said in a September 5, 2016 statement:
The images were taken on 2 September by the OSIRIS narrow-angle camera as the orbiter came within 2.7 km of the surface and clearly show the main body of the lander, along with two of its three legs.
The images also provide proof of Philae’s orientation, making it clear why establishing communications was so difficult following its landing on 12 November 2014.
Cecilia Tubiana of the OSIRIS camera team, the first person to see the images when they were downlinked from Rosetta on September 4, 2016, said:
With only a month left of the Rosetta mission, we are so happy to have finally imaged Philae, and to see it in such amazing detail.
Patrick Martin, ESA’s Rosetta Mission Manager, said:
This remarkable discovery comes at the end of a long, painstaking search. We were beginning to think that Philae would remain lost forever. It is incredible we have captured this at the final hour.
The discovery comes less than a month before Rosetta descends to the comet’s surface, ESA said. On September 30, the orbiter will be sent on a final one-way mission to investigate the comet from close up, in what ESA has called a “controlled descent” to the comet’s surface.
Bottom line: With only a month left of the Rosetta mission, the Philae comet lander has been found wedged into a dark crack on Comet 67P/Churyumov–Gerasimenko.
Deborah Byrd created the EarthSky radio series in 1991 and EarthSky.org in 1994. Today, she serves as Editor-in-Chief of this website. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named 3505 Byrd in her honor. A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says.
