'''''Beresheet''''' ({{lang-he|בְּרֵאשִׁית}}, ''Bərēšīṯ'', "In the beginning"; [[Religion:Book of Genesis|Book of Genesis]]) was a demonstrator of a small robotic lunar lander and lunar probe operated by [[Engineering:SpaceIL|SpaceIL]] and Israel Aerospace Industries. Its aims included inspiring youth and promoting careers in science, technology, engineering, and mathematics ([[Engineering:Science, technology, engineering, and mathematics|STEM]]), and landing its [[Physics:Magnetometer|magnetometer]], [[Astronomy:Time capsule|time capsule]], and [[Organization:Retroreflector|laser retroreflector]] on the [[Astronomy:Moon|Moon]]. The lander's gyroscopes failed on 11 April 2019 causing the main engine to shut off, which resulted in the lander crashing on the Moon.<ref>{{cite web|url=https://www.timesofisrael.com/israels-beresheet-spacecraft-crashes-during-moon-landing-attempt/|title=Israel's Beresheet spacecraft crashes into the moon during landing attempt|first=Melanie|last=Lidman|newspaper=The Times of Israel}}</ref> Its final resting position is 32.5956°N, 19.3496°E.<ref name="LROC crash spotted">{{cite web |url=http://lroc.sese.asu.edu/posts/1101|title=Beresheet Crash Site Spotted! {{!}} Lunar Reconnaissance Orbiter Camera|publisher=Lunar Reconnaissance Orbiter Camera (LROC), School of Earth and Space Exploration, Arizona State University|access-date=2019-09-19}}</ref>

The lander was previously known as '''''Sparrow''''' and was officially renamed to ''Beresheet'' in December 2018.<ref>[http://www.spaceil.com/general/spaceil-iai-to-send-time-capsule-on-israels-historic-moon-mission/ SpaceIL, IAI to send time capsule on Israel's historic Moon mission] {{Webarchive|url=https://web.archive.org/web/20190330040247/http://www.spaceil.com/general/spaceil-iai-to-send-time-capsule-on-israels-historic-moon-mission/|date=30 March 2019}} SpaceIL website Retrieved 17 December 2018</ref> Its net mass was {{cvt|150|kg}}; when fueled at launch, its mass was {{cvt|585|kg}}.

== Planning and construction ==
''Beresheet'' was co-developed by [[Engineering:SpaceIL|SpaceIL]] and Israel Aerospace Industries (IAI) with support from Israel Space Agency and Morris Kahn, its major financier. It represented the first privately initiated Moon mission and was stimulated by the Google Lunar X Prize.<ref name="Deutsche Welle 2019-02-19">{{cite web|publisher=Deutsche Welle|url=https://www.dw.com/de/israel-schickt-ersten-privat-finanzierten-mond-lander-auf-den-weg/a-47534715|title=Israel schickt ersten privat finanzierten Mond-Lander auf den Weg|language=de|trans-title=Israel sends first privately financed lunar lander on its way |date=19 February 2019|access-date=11 April 2019}}</ref> SpaceIL and IAI constructed the vehicle <ref>{{cite web |url=https://astronaut.com/spaceil-says-chain-of-events-led-to-crash-of-lunar-lander/ |title=SpaceIL says "chain of events" led to crash of lunar lander |access-date=19 November 2019 |archive-date=20 October 2021 |archive-url=https://web.archive.org/web/20211020140838/https://astronaut.com/spaceil-says-chain-of-events-led-to-crash-of-lunar-lander/ |url-status=dead }}</ref> and was supported by the Israel Space Agency.<ref>{{cite web|author=Christine Lunsford |url=https://www.space.com/43188-israel-first-moon-lander-spaceil-beresheet-photos.html|title=Israel's 1st Moon Lander: The SpaceIL Beresheet Lunar Mission in Pictures|website=Space.com|date=9 February 2019|access-date=19 February 2019}}</ref> The time window for participation in the Google Lunar X Prize closed before the launch.

== Planned operations ==
''Beresheet'' was planned to operate for an estimated two days on the lunar surface,<ref name="Times of Israel 2018-07-10"/> as it had no thermal control and was expected to quickly overheat.<ref>[https://www.heritagefl.com/story/2019/01/11/news/with-spaceil-launch-its-to-the-moon-and-beyond-for-israel/10930.html With SpaceIL launch, its to the Moon and beyond for Israel] Yaakov Lappin, ''Heritage'' 11 January 2019</ref> Its main mission would have been to gather imagery and send it back to Earth.

=== NASA contribution ===
In addition to contributing the laser retroreflector to the mission, NASA planned to contribute space communications capabilities during the cruise phase and operations phase, even giving ''Beresheet'' time on the [[Astronomy:NASA Deep Space Network|Deep Space Network]]. NASA also planned to survey ''Beresheet'' with its [[Astronomy:Lunar Reconnaissance Orbiter|Lunar Reconnaissance Orbiter]] (which it did after the crash-landing). In exchange, SpaceIL would have shared its magnetic measurements with NASA.<ref name="The Verge 2019-02-19"/>

== Crash landing ==
[[File:Beresheet Crash Site Spotted LRO 02.gif|thumb|upright=1.0|right|Crash site of ''Beresheet'' as seen by the Lunar Reconnaissance Orbiter.]]

On 11 April 2019, the lander crash-landed on the lunar surface. An Inertial Measurement Unit (IMU2) [[Engineering:Gyroscope|gyroscope]] failed during the braking procedure on approach to the landing site, and the ground control crew was unable to reset the individual component due to a sudden loss of communications with the control network.<ref>{{cite AV media|url=https://www.youtube.com/watch?v=HMdUcchBYRA|title=LIVE broadcast - Beresheet lands on the Moon Fasten your seatbelts, we are about to land|medium=Live videocast|date=11 April 2019|publisher=SpaceIL|location=Yehud, Israel|access-date=12 April 2019}} commentary beginning 32'56" (combined Hebrew and English)</ref> By the time communications were restored, the craft's main engine had already been inactive for an extended period.

===Post-mission failure investigation ===
Several malfunctions plus [[Human-in-the-loop|human-in-the-loop]] decisions led to the crash landing during the final lunar descent. These were the result of limited funding; poor systems engineering design with a lack of redundancy in some systems and an inability of telemetry-software updates to remain active following system reboot; as well as human decisions about which path to take after the failure of one of the two redundant accelerometers ([[Engineering:Inertial measurement unit|inertial measurement unit]]s, or IMUs) during the final lunar descent. A decision was made by the control team—which could have continued the descent with a single IMU, or tried to reinitiate the IMU which had shut down—to restart the second IMU.<ref name=wi20200220/> 

Due to the design of the spacecraft, restarting the IMU blocks communication with the functioning IMU. For less than one critical second, the spacecraft did not receive any acceleration data from the good IMU, and as programmed, identified it as a navigation malfunction, which caused a reboot of the spacecraft computer. The reboot lasted only approximately two seconds, but since the spacecraft design did not allow for previous software updates to be loaded automatically from the hard drive on reboot, the software patches had to be uploaded once again as a command file. Five tries were needed to get the updates to load, with the computer rebooting each time, and the main engine shut down during the reboots. Since the engine was needed to be continuously firing during the descent to decelerate ''Beresheet'', the spacecraft retained excessive speed and struck the lunar surface at {{cvt|3000|km/h}}.<ref name=wi20200220>{{cite report |title=What Happened to Beresheet? |url=https://davidson.weizmann.ac.il/en/online/sciencepanorama/what-happened-beresheet |last=Nevo|first=Ettay |publisher=Weizman Institute of Science |date=20 February 2020 |access-date=17 January 2024}}</ref>

== Wreckage ==
NASA's [[Astronomy:Lunar Reconnaissance Orbiter|Lunar Reconnaissance Orbiter]] (LRO) overflew the area where ''Beresheet''{{'s}} telemetry ended, and took photos of the surface. When those photos were compared against earlier photos of the same location, one set of new features was obvious. A faint lighter line leads to a lighter halo surrounding a dark crater. A lump is visible at the head of the crater opposite the line. The light halo may either be gas associated with the craft's wreckage or fine soil particles blown outward by the impact.<ref>{{cite news|url=https://www.space.com/beresheet-moon-lander-crash-site-photos.html|title=Moon Crash Site Found!

On 9 December 2020, SpaceIL announced that the ''Beresheet 2'' Moon mission will launch in 2024, and will consist of an orbiter and two landers. It will have a budget of US$100 million, similar to that of ''Beresheet 1'', and will include more international collaboration, with the [[Place:United Arab Emirates|United Arab Emirates]] as one of seven countries expressing interest.<ref name="toi-20201209">{{cite web |url=https://www.timesofisrael.com/beresheet-2-israel-launches-plan-for-second-moon-shot-in-2024-uae-may-join/|title=Israel launches second bid to put a lander on the moon; UAE may join|newspaper=The Times of Israel|date=9 December 2020|access-date=10 December 2020}}</ref>
