840-477: 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. The impact was not as visually prominent as had been anticipated. Project manager Dan Andrews believed that this

875-423: The spacecraft. 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. 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. LCROSS was a fast-track, low-cost companion mission to

910-456: The spacecraft. LCROSS passed its review on February 12, 2009. 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

945-446: The spectra indicate that a reasonable estimate of the concentration of water in the frozen regolith is on the order of one percent. 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. A later, more definitive, analysis found the concentration of water to be "5.6 ± 2.9% by mass." On August 20, 2018, NASA confirmed ice on

980-420: 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, and its Critical Design Review on February 22, 2007.

This test cell is 240 feet long by 33 feet wide. The inlet height

1085-444: Was due to pre-crash simulations that exaggerated the plume's prominence. 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. On November 13, 2009, NASA reported that multiple lines of evidence show water

1120-481: 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

1155-471: 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

1190-573: 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

1225-463: Was present in both the high-angle vapor plume and the ejecta curtain created by the LCROSS Centaur impact. As of November 2009 , 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
