The Lunar CRater Observation and Sensing Satellite (LCROSS) mission was designed to search for evidence of water in a permanently shadowed region near the lunar south pole… Number of known asteroids reaches 1 million, Science X Daily and the Weekly Email Newsletter are free features that allow you to receive your favorite sci-tech news updates in your email inbox. Each orbit will be roughly perpendicular to the moon's orbit around Earth and take about 37 days to complete. NASA launched its first moon shot in a decade Thursday, sending up a pair of unmanned science probes that will help determine where astronauts could land and set up camp in years to come.

"We stand poised for an amazing mission and possible answers to some very intriguing questions about the moon.". The 1,290-pound LCROSS and 5,216-pound Centaur upper stage will perform a swing-by maneuver of the moon around 5 a.m. on June 23 to calibrate the satellite's science instruments and enter a long, looping polar orbit around Earth and the moon. On the final approach, about 54,000 miles above the surface, LCROSS and the Centaur will separate. xmlns:xsl='http://www.w3.org/1999/XSL/Transform'">. LCROSS and its attached Centaur upper stage rocket separately will collide with the moon at approximately 6:30 a.m. on Oct. 9, 2009, creating a pair of debris plumes that will be analyzed for the presence of water ice or water vapor, hydrocarbons and hydrated materials. NASA's Lunar CRater Observation and Sensing Satellite, or LCROSS, mission has won Popular Mechanics magazine's 2010 Breakthrough Award for innovation in science and technology. LCROSS's mission was dedicated to late American broadcaster Walter Cronkite. The LCROSS science team will lead a coordinated observation campaign that includes LRO, the Hubble Space Telescope, observatories on Hawaii's Mauna Kea and amateur astronomers around the world. The spacecraft will observe the flash from the Centaur's impact and fly through the debris plume. The satellite lifted off on an Atlas V rocket from Cape Canaveral Air Force Station, Fla., at 4:32 p.m. CDT, with a companion mission, the Lunar Reconnaissance Orbiter, or LRO.

LCROSS will spin 180 degrees to turn its science payload toward the moon and fire thrusters to slow down. Thank you for taking your time to send in your valued opinion to Science X editors. Apart from any fair dealing for the purpose of private study or research, no Northrop Grumman in Redondo Beach, Calif., built the spacecraft. The exact target crater will be identified 30 days before impact, after considering information collected by LRO, other spacecraft orbiting the moon, and observatories on Earth.

"LCROSS has been the little mission that could," said Doug Cooke, associate administrator for NASA's Exploration Systems Mission Directorate at NASA Headquarters in Washington. Images and information about impact studies conducted at the Ames Vertical Run Range. LCROSS then was powered-up, and the mission operations team at NASA's Ames Research Center at Moffett Field, Calif., performed system checks that confirmed the spacecraft is fully functional.

Preliminary data from the Lunar CRater Observation and Sensing Satellite indicates that the mission successfully uncovered water during the Oct. 9, 2009, impacts near the moon's south pole. The LCROSS spacecraft following four minutes behind will collect and transmit data back to LCROSS mission control about the debris plume using the nine on-board science instruments before impacting the surface. The LCROSS shepherding spacecraft and the Atlas V’s Centaur upper stage rocket executed a fly-by of the moon on June 23, 2009 (LCROSS lunar swingby video stream coverage) and entered into an elongated Earth orbit to position LCROSS for impact on a lunar pole. Data will be collected and streamed to LCROSS mission operations for analysis. Click here to sign in with Proposing the use the Centaur as a lunar kinetic impactor, LCROSS would “drop” the 2300 Kg rocket (about the weight of a large sports utility vehicle) into a permanently-shadowed crater, at a speed of 1.5 miles/second (2.5 km/s) or three times the speed of a bullet, to kick-up a … A possible result of the impact is the creation of a temporary thin atmosphere of hydroxyl ions. LRO safely separated from LCROSS 45 minutes later. NASA - National Aeronautics and Space Administration, Follow this link to skip to the main content. "This mission is the culmination of a dedicated team that had a great idea," said Daniel Andrews, LCROSS project manager at Ames. The LCROSS payload was added after NASA moved the LRO from the Delta II to a larger launch vehicle. Your opinions are important to us. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); NASA successfully launched the Lunar Crater Observation and Sensing Satellite, or LCROSS, Thursday on a mission to search for water ice in a permanently shadowed crater at the moon's south pole. LCROSS was a fast-track, low-cost companion mission to the LRO. Before impact, the spacecraft and Centaur will make approximately three orbits. and Terms of Use. Ames manages LCROSS and also built the instrument payload. How does the observable universe have meaning?
