A Japanese moon explorer is up and running Monday after several tense days without the sunlight it needs to generate power. Japan's first lunar mission hit its target in a precision touchdown on Jan. 20, but it landed the wrong way up, leaving its solar panels unable to see the sun, per the AP. But with the dawn of the lunar day, it appears that the probe now has power. The Japan Aerospace Exploration Agency, or JAXA, said Monday it successfully established communication with the probe Sunday night, and that the craft has resumed its mission, taking pictures of the moon's surface and transmitting them to Earth.
After a last-minute engine failure caused the Smart Lander for Investigating Moon, or SLIM, to make a rougher-than-planned landing, JAXA used battery power to gather as much data as possible about the touchdown and the probe's surroundings. The craft was then turned off to wait for the sun to rise higher in the lunar sky in late January. With power, SLIM has continued work to analyze the composition of olivine rocks on the lunar surface with its multiband spectral camera, seeking clues about the moon's origin and evolution, the agency said. Earlier observations suggest that the moon may have formed when the Earth hit another planet. A black-and-white photo posted by JAXA on social media showed the rocky lunar surface, including a rock the agency said it had named "Toy Poodle" after seeing it in initial images.
The probe is analyzing six rocks, all of which have been given the names of dog breeds. SLIM is expected to have enough sun to continue operations for several Earth days, possibly until Thursday. JAXA said it's not clear if the craft will work again after another severely cold lunar night. SLIM—which landed about 60 yards away from its target, in between two craters near the Shioli Crater, a region covered in volcanic rock—carried two autonomous probes, which were released just before touchdown, recording the landing, surroundings, and other lunar data.
