At 1130 GMT the LCROSS satellite crashed into the Cabeus crater floor near the moon's south pole at around 5,600 miles (9,000 kilometers) per hour, followed four minutes later by a shepherding spacecraft equipped with cameras to record the impact.Grainy thermal images carried on the US space agency's television station showed colder blue sites and warmer red sites on the moon's surface, but there was no apparent light flash as the rockets made impact.NASA said the blasts would kick up a plume of lunar dirt to an altitude of about 6.2 miles (10 kilometers) and produce a flash lasting about 30 seconds.Cameras mounted on the 1,965-pound (891-kilogram) shepherding spacecraft were to beam live footage of the initial impact as the craft flew through the debris plume, collecting and relaying key data back to Earth before it too plows into the moon."The LCROSS science team is making their preliminary assessment of approximately four minutes of data collected from the LCROSS Spacecraft. Observatories involved in the LCROSS Observation Campaign are reporting in," the mission website said after the impact."We don't anticipate anything about presence or absence of water immediately. It's going to take us some time," cautioned Anthony Colaprete, project scientist and principal investigator for the 79-million-dollar LCROSS mission, which is also the first preparatory mission of the Constellation program that aims to send Americans back to the moon by 2020.Colaprete projected it would take several days for analysts to evaluate the data and several weeks to determine whether and how much hydrogen-bearing compounds were found.
