Well, hello there, Philae.
The famous little probe — the first one to ever land on a comet — has been silent for more than a year, after a less-than-perfect landing left it struggling to get enough sunlight to recharge its batteries. And now — thanks to a high-resolution photo — we finally know where it is.
The lander, carried by the Rosetta spacecraft on a European Space Agency mission, had been eagerly watched from Earth throughout its mission. A few successful hours of communication were celebrated, and then it was clear they couldn’t last.
The problem, as NPR’s Nell Greenfieldboyce tells our Newscast unit, was that Philae hadn’t ended up where it was supposed to. And as a result, no one knew exactly where it was.
“Instead of landing on a flat spot as planned, it bounced and flew for another two hours, ending up … somewhere,” she says. “Controllers could talk to it, but its exact whereabouts remained unknown.”
Before it shut down, Philae did send photos showing its landing spot. But the gray rocky scene it showed was, well, less than distinctive.
But now, with just one month left on its mission, the Rosetta spacecraft flew near the comet and caught a glimpse of the lander’s predicament.
It’s now clear why the lander had so much trouble recharging and communicating: It turns out the washing-machine-sized lander is wedged in a shadowy crack.
The photos from Rosetta, taken “unprecedentedly close” to the comet, show the main body of the lander and two of its three legs, ESA says in a blog post.
“This remarkable discovery comes at the end of a long, painstaking search,” Patrick Martin, ESA’s Rosetta Mission Manager, says in the post. “We were beginning to think that Philae would remain lost forever. It is incredible we have captured this at the final hour.”
On Sept. 30, Rosetta will take an even closer look at the comet — by crash-landing on it. Spacecraft and lander will be together again, each quiet and still, on the surface of Comet 67P.
