SpaceIL, an Israeli nonprofit organization, is dedicated to landing the first Israeli spacecraft on the Moon. Beresheet was their first attempt at meeting this goal. While the spacecraft did land, it first touched the surface about 1000 meters per second faster than intended. The mishap occurred late in the descent profile when the main engine failed—resulting in a very low-angle (<10°), high-speed impact.

The Beresheet impact occurred on 11 April 2019 and LRO passed overhead 11 days later, allowing LROC to acquire a six-image (three NAC left-right pairs) sequence of the search area. The coordinates of the darkest pixel (lowest reflectance) of the central "smudge" are 32.5956°N, 19.3496°E, with a 20-m (latitude) by 8-m (longitude) 95% confidence interval, estimated from seven images acquired before the impact event (over the course of the LRO mission). The elevation is ~2613 meters, and although the uncertainty is not well constrained at this time, it is likely less than 10 meters.

What really happened is they encountered this.

Israel's SpaceIL says it won't try second moonshot

SpaceIL, the Israeli company that attempted but failed to put an unmanned craft on the moon earlier this year, says it will not try a second moonshot.

The company issued a statement Tuesday saying its lunar mission in April has been widely hailed as "an exceptional success," despite crash landing on the moon. It says that "an attempt to repeat a trip to the moon is not enough of a challenge" and will instead search for a different mission.

    Maybe it's because I'm old and when Armstrong landed on the moon I had 2 mikes on my reel to reel tape recorder, one on each side of my mono TV, for stereo (cut me a break, I was 11 years old).

    It's amazeballs we can see images like this nowdays.

    I've had more than my share of those landings when trying to put something on the Mun.

    "land" and "touch" don't quite reflect how spectacular this would have looked to a local observer:
    That's equivalent to a Mach-3 crash, OR about 40% of the local escape velocity.

    Did they find any Aristarchus submissions? I mean, other than in the Aristarchus Crater, where of course one would find aristarchus submissions, and submit them, since they are from a Crater on the Fucking Moon! Sometimes I think our Soylent Editors are completely Earth bound, like that.

        Are you suggesting I was wrong? Well of course, instruments are much more precise today! Do you not think I keep up?

          The error in this calculation comes primarily from the poor values for x and θ. The poor value for θ is especially surprising, since Archimedes writes that Aristarchus...

            A good craftsman never blames his tools:

            Ah, but a good scientist always mistrusts his instruments, and seeks to develop better ones. And it is a good idea to actually read your citations before you cite them, lest they undercut your case.

            The disagreement of the work with Archimedes seems to be due to its taking an Aristarchus statement that the lunisolar diameter is 1/15 of a "meros" of the zodiac to mean 1/15 of a zodiacal sign (30°), unaware that the Greek word "meros" meant either "portion" or 7°1/2; and 1/15 of the latter amount is 1°/2, in agreement with Archimedes' testimony.
