A processed image from NASA\u2019s Lunar Reconnaissance Orbiter, taken on April 22, highlights the dark smudge and bright impact halo left behind by the Beresheet lunar lander\u2019s impact (NASA \/ GSFC \/ ASU Photo)<\/figcaption><\/figure>\n

The Israeli-built Beresheet moon lander made history when it went into lunar orbit and descended to the surface \u2014 and although it didn\u2019t survive its crash landing, it did leave a mark that\u2019s likely to endure for millennia.<\/p>\n

Weeks after the April 11 smashup, NASA has released imagery from its Lunar Reconnaissance Orbiter showing the dark blast site and spray of debris that Beresheet kicked up.<\/p>\n

The orbiter was over the horizon when the lander fell to the surface due to a last-minute programming glitch and engine shutdown. But it was in a good position to snap a picture of the crash site on April 22 from a height of 56 miles (90 kilometers).<\/p>\n

Here\u2019s how NASA interpreted the image in Wednesday\u2019s advisory:<\/p>\n

\n

\u201cThe cameras captured a dark smudge, about 10 meters wide, that indicates the point of impact. The dark tone suggests a surface roughened by the hard landing, which is less reflective than a clean, smooth surface.<\/p>\n

\u201cFrom so far away, LROC could not detect whether Beresheet formed a surface crater upon impact. It\u2019s possible the crater is just too small to show up in photos. Another possibility is that Beresheet formed a small indent instead of a crater, given its low angle of approach (around 8.4 degrees relative to the surface), light mass (compared to a dense meteoroid of the same size), and low velocity (again, relative to a meteoroid of the same size; Beresheet\u2019s speed was still faster than most speeding bullets).<\/p>\n

\u201cThe light halo around the smudge could have formed from gas associated with the impact or from fine soil particles blown outward during Beresheet\u2019s descent, which smoothed out the soil around the landing site, making it highly reflective.\u201d<\/p>\n<\/blockquote>\n

Analysts linked the impact site to Beresheet rather than a run-of-the-mill meteoroid by matching up its coordinates with Beresheet\u2019s final transmissions, and by comparing before-and-after images of the site. The shape of the bright tail of debris is also consistent with what would be expected from a spacecraft impact.<\/p>\n

Researchers are still working on an experiment that involves sending out laser pulses from LRO\u2019s Lunar Orbiter Laser Altimeter and seeing if they bounce back from a mirror-laden laser retroreflector array that was mounted on Beresheet\u2019s top deck. Even though the lander was almost certainly blasted apart, there\u2019s a chance that the retroreflector survived.<\/p>\n

Meanwhile, the privately backed SpaceIL team that built Beresheet (which takes its name the Hebrew word for \u201cIn the Beginning\u201d) is hard at work on Beresheet 2.<\/p>\n
