Israel's Moon probe snaps a final photo before crashing

Posted By TheNewsCommenter: From Engadget.com: “Israel's Moon probe snaps a final photo before crashing”. Below is an excerpt from the article.

The Beresheet spacecraft from Israel's SpaceIL was facing long odds to land on the Moon, being the first ever privately launched probe to attempt it. Alas, its engine cut out during the landing attempt, communication was lost, and Beresheet crashed into the surface. Fortunately, just before that happened, the spacecraft turned its camera toward the Moon's horizon and managed to snap a final, sublime photo of its cratered surface.

SpaceIL was one of the finalists for Google's Lunar Xprize, which ended without a winner. Had the probe landed, it would have carried several scientific experiences. That includes measuring the local magnetic field using a magnetometer and carrying a NASA-made laser retroreflector array to measure the precise distance between the Earth and the Moon. It also brought a time capsule containing a copy of the English-language Wikipedia, the Wearable Rosetta Disk, the Torah, children's drawings, memoirs of a Holocaust survivor and more.

A SpaceX Falcon 9 rocket launched Beresheet into a high Earth orbit on February 22nd. It spent the next couple of months leisurely making its way toward the Moon's orbit, and was supposed to land on the northern hemisphere. The technique, while unusual, was designed to save fuel -- once the probe landed, it would have had power for only a couple of days at most.

Unfortunately, during the approach, the engine stopped. Mission control managed to bring it back online after performing a system reset, but the probe had already lost too much altitude to shed the excessive speed. When it contacted the surface, it was traveling at about 300MPH vertically, according to the final telemetry values.

Minutes before that happened, it snapped the a selfie with the rapidly approaching Moon in the background. Shortly after that, it snapped the much closer photo at top.
