It was launched together with the Lunar Reconnaissance Orbiter (LRO) on June 18, 2009, as part of the shared Lunar Precursor Robotic Program, the first American mission to the Moon in over ten years.

LCROSS was designed to collect and relay data from the impact and debris plume resulting from the launch vehicle's spent Centaur upper stage (and data-collecting Shepherding Spacecraft) striking the crater Cabeus near the south pole of the Moon.

Centaur had nominal impact mass of 2,305 kg (5,081 lb), and an impact velocity of about {{convert|9000|km/h|mph|abbr=on}},{{cite web|url=https://www.nasa.gov/centers/ames/news/features/2009/LCROSS_new_crater.html|title=NASA's LCROSS Mission Changes Impact Crater|publisher=NASA|date=September 29, 2009|access-date=November 21, 2009|archive-url=https://web.archive.org/web/20091028005912/http://www.nasa.gov/centers/ames/news/features/2009/LCROSS_new_crater.html|archive-date=October 28, 2009}} releasing the kinetic energy equivalent of detonating approximately 2 tons of TNT (7.2 TJ).

LCROSS suffered a malfunction on August 22, depleting half of its fuel and leaving very little fuel margin in the spacecraft.{{cite web

Centaur impacted successfully on October 9, 2009, at 11:31 UTC. The Shepherding Spacecraft descended through Centaur's ejectate plume, collected and relayed data, impacting six minutes later at 11:37 UTC.[https://www.thestar.com/sciencetech/article/707964--nasa-crashes-rocket-into-moon TheStar.com], "NASA crashes rocket into moon".

Contrary to media reports at the time, neither the impact nor its dust cloud could be seen from Earth, using the naked eye or telescopes.

Mission

File:LCROSS Centaur Impact Flash.jpg

LCROSS was a fast-track, low-cost companion mission to the LRO. The LCROSS payload was added after NASA moved the LRO from the Delta II to a larger launch vehicle. It was chosen from 19 other proposals.{{cite news|url=https://www.space.com/2276-nasa-adds-moon-crashing-probes-lro-mission.html|title=NASA Adds Moon Crashing Probes to LRO Mission|work=Space.com|date=April 10, 2006|access-date=April 11, 2006|author=Tariq Malik}} LCROSS's mission was dedicated to late American broadcaster Walter Cronkite.{{cite news|url=https://www.thestar.com/business/tech_news/2009/10/09/nasa_crashes_rocket_into_moon.html|title=NASA crashes rocket into moon|date=October 9, 2009|access-date=October 9, 2009|work=Toronto Star}}

LCROSS launched with the LRO aboard an Atlas V rocket from Cape Canaveral, Florida, on June 18, 2009, at 21:32 UTC (17:32 EDT). On June 23, four and a half days after launch, LCROSS and its attached Centaur booster rocket successfully completed a lunar swingby and entered into polar Earth orbit with a period of 37 days, positioning LCROSS for impact on a lunar pole.{{cite web

Early in the morning on August 22, 2009, LCROSS ground controllers discovered an anomaly caused by a sensor problem, which had resulted in the spacecraft using up 140 kilograms (309 pounds) of fuel, more than half of the fuel remaining at the time. According to Dan Andrews, the LCROSS project manager, "Our estimates now are if we pretty much baseline the mission, meaning just accomplish the things that we have to [do] to get the job done with full mission success, we're still in the black on propellant, but not by a lot."

Lunar impacts, after approximately three orbits, occurred on October 9, 2009, with the Centaur crashing into the Moon at 11:31 UTC and the Shepherding Spacecraft following a few minutes later.{{cite news|url=https://news.yahoo.com/s/ap/20091009/ap_on_sc/us_sci_shoot_the_moon |title=NASA probes give moon a double smack |agency=Associated Press |date=October 9, 2009 |access-date=October 9, 2009 |author=Seth Borenstein |url-status=dead |archive-url=https://web.archive.org/web/20091009114926/http://news.yahoo.com/s/ap/20091009/ap_on_sc/us_sci_shoot_the_moon |archive-date=October 9, 2009}} The mission team initially announced that Cabeus A would be the target crater for the LCROSS dual impacts,{{cite web|url=http://lcross.arc.nasa.gov/observation.htm |title=LCROSS Observation Campaign |publisher=NASA |url-status=dead |archive-url=https://web.archive.org/web/20120504042620/http://lcross.arc.nasa.gov/observation.htm |archive-date=May 4, 2012 }} but later refined the target to be the larger, main Cabeus crater.{{cite web |url= https://www.nbcnews.com/id/wbna33064495 |title= Moon-crashing probe aimed at bigger target |date= September 29, 2009 |publisher= NBC News}}

On its final approach to the Moon, the Shepherding Spacecraft and Centaur separated October 9, 2009, at 01:50 UTC.{{cite web |url= https://www.nasa.gov/mission_pages/LCROSS/main/index.html |title= NASA - LCROSS |publisher= NASA}} The Centaur upper stage acted as a heavy impactor to create a debris plume that rose above the lunar surface. Following four minutes after impact of the Centaur upper stage, the Shepherding Spacecraft flew through this debris plume, collecting and relaying data back to Earth before it struck the lunar surface to produce a second debris plume. The impact velocity was projected to be {{convert|9000|km/h|mph|abbr=on}} or 2.5 km/second.{{cite web

The Centaur impact was expected to excavate more than {{convert|350|MT|ST||lk=on}} of lunar material and create a crater about 27 m (90 ft) in diameter to a depth of about {{convert|5|m|abbr=on}}. The Shepherding Spacecraft impact was projected to excavate an estimated {{convert|150|MT|ST}} and create a crater approximately 18 m (60 ft) in diameter to a depth of about 3 m (10 ft). Most of the material in the Centaur debris plume was expected to remain at (lunar) altitudes below {{convert|10|km|0|abbr=on}}.

It was hoped that spectral analysis of the resulting impact plume would help to confirm preliminary findings by the Clementine and Lunar Prospector missions which hinted that there may be water ice in the permanently shadowed regions. Mission scientists expected that the Centaur impact plume would be visible through amateur-class telescopes with apertures as small as 25 to 30 cm (10 to 12 inches).

But no plume was observed by such amateur telescopes. Even world class telescopes such as the Hale Telescope, equipped with adaptive optics, did not detect the plume. The plume may have still occurred but at a small scale not detectable from Earth.

Both impacts were also monitored by Earth-based observatories and by orbital assets, such as the Hubble Space Telescope.

Whether or not LCROSS would find water had been stated to be influential in whether or not the United States government pursues creating a Moon base.{{cite news|url=http://english.chosun.com/site/data/html_dir/2009/10/09/2009100900348.html|access-date=October 9, 2009|date=October 9, 2009|newspaper=The Chosun Ilbo|title=NASA's Rocket Crash Might Boost Plans for Moon Colonies}} On November 13, 2009, NASA confirmed that water was detected after the Centaur impacted the crater.

Spacecraft

The LCROSS mission took advantage of the structural capabilities of the Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) ring{{cite web|url=https://digitalcommons.usu.edu/cgi/viewcontent.cgi?article=2028&context=smallsat|title=Evolved expendable launch vehicle secondary payload adapter - A New Delivery System for Small Satellites|format=PDF}} used to attach LRO to the Centaur upper-stage rocket to form the Shepherding Spacecraft. Mounted on the outside of the ESPA were six panels that hold the spacecraft's science payload, command and control systems, communications equipment, batteries, and solar panels. A small monopropellant propulsion system was mounted inside of the ring. Also attached were two S Band omnidirectional antennas and two medium-gain antennas. The mission's strict schedule, mass, and budget constraints posed difficult challenges to engineering teams from NASA Ames Research Center (ARC) and Northrop Grumman. Their creative thinking led to a unique use of the ESPA ring and innovative sourcing of other spacecraft components. Usually, the ESPA ring is used as a platform to hold six small deployable satellites; for LCROSS, it became the backbone of the satellite, a first for the ring. LCROSS also took advantage of commercially available instruments and used many of the already-flight-verified components used on LRO.{{Cite web|url=https://www.nasa.gov/mission_pages/LCROSS/spacecraft/Spacecraft1.html|title=NASA - LCROSS Spacecraft|website=www.nasa.gov|language=en|access-date=January 16, 2020}}

LCROSS is managed by NASA's ARC and was built by Northrop Grumman. The LCROSS preliminary design review was completed on September 8, 2006. The LCROSS mission passed its Mission Confirmation Review on February 2, 2007,{{cite news|url=https://www.nasa.gov/home/hqnews/2007/feb/HQ_0721_LCROSS.html|title=NASA Moon-Impactor Mission Passes Major Review|publisher=www.nasa.gov|date=February 2, 2007}} and its Critical Design Review on February 22, 2007.{{cite news|url=http://www.moondaily.com/reports/Lunar_Crater_Observation_and_Sensing_Satellite_Passes_Critical_Design_Review_999.html|title=Lunar Crater Observation and Sensing Satellite Passes Critical Design Review|publisher=Moondaily.com|date=March 2, 2007}}

=Instruments=

The LCROSS Shepherding Spacecraft science instrument payload, provided by NASA's ARC, consisted of a total of nine instruments: one visible, two near infrared, and two mid-infrared cameras; one visible and two near-infrared spectrometers; and a photometer. A data handling unit (DHU) collected the information from each instrument for transmission back to LCROSS Mission Control. Because of the schedule and budget constraints, LCROSS took advantage of rugged, commercially available components. The individual instruments went through a rigorous testing cycle that simulated launch and flight conditions, identifying design weaknesses and necessary modifications for use in space, at which point the manufacturers were allowed to modify their designs.

Results

The impact was not as visually prominent as had been anticipated. Project manager Dan Andrews believed that this was due to pre-crash simulations that exaggerated the plume's prominence.{{citation needed|date=November 2013}} Because of data bandwidth issues, the exposures were kept short, which made the plume difficult to see in the images in the visible spectra. This resulted in the need for image processing to increase clarity. The infrared camera also captured a thermal signature of the booster's impact.{{cite magazine |url=http://www.scientificamerican.com/blog/post.cfm?id=lcross-strikes-earths-moon-as-other-2009-10-09 |date=October 9, 2009 |title=LCROSS strikes Earth's moon as other moons continue to puzzle: Fourth dispatch from the annual planets meeting |first=George |last=Musser |magazine=Scientific American |quote=Shortly before the spacecraft itself hit, word came through that the infrared camera had indeed seen a thermal signature of the booster's crater.}}

=Presence of water=

On November 13, 2009, NASA reported that multiple lines of evidence show water was present in both the high-angle vapor plume and the ejecta curtain created by the LCROSS Centaur impact. {{As of|2009|11}}, the concentration and distribution of water and other substances required more analysis. Additional confirmation came from an emission in the ultraviolet spectrum that was attributed to hydroxyl fragments, a product from the break-up of water by sunlight.

Analysis of the spectra indicate that a reasonable estimate of the concentration of water in the frozen regolith is on the order of one percent.{{cite news |url=https://www.sfgate.com/cgi-bin/article.cgi?f=/2009-11-14/news/17180950_1_crater-vapor-water |work=The San Francisco Chronicle |first=David |last=Perlman |title=NASA chooses moon crater for crash of rocket |date=November 14, 2009 |url-status=live |archive-url=https://web.archive.org/web/20100325182007/http://articles.sfgate.com/2009-11-14/news/17180950_1_crater-vapor-water |archive-date=March 25, 2010 }} Evidence from other missions suggests that this may have been a relatively dry spot, as thick deposits of relatively pure ice appear to present themselves in other craters.[https://www.nasa.gov/mission_pages/Mini-RF/multimedia/feature_ice_like_deposits.html NASA - NASA Radar Finds Ice Deposits at Moon's North Pole] A later, more definitive, analysis found the concentration of water to be "5.6 ± 2.9% by mass."{{cite journal
