Lunar grit kicked up michael kors outlet black friday sales 2014 by meteorite impacts moves at the speed of a shotgun blast, posing a potential risk to future astronauts. But such high speed projectiles need not be a show stopper for long term lunar missions, provided we beef up the structural integrity of buildings, rovers and spacesuits. "You have to have a suit or habitat design that can handle small meteors, and that may just as well handle these secondary ejecta particles," says Rob Suggs, head of the Lunar Impact Monitoring team at NASA's Marshall Space Flight Center in Huntsville, Alabama. The airless moon is already pockmarked with craters made by incoming space rocks, and the bombardment is ongoing. With low gravity and no air resistance, dirt from an impact can be scattered far and wide. NASA michael kors outlet online redemption code worried about the risks from impact debris during the Apollo era, but at the time little was known about how often objects hit the moon and the speed of any material they kick up. In 2006, NASA was working on the Constellation programme, which aimed to send humans back to the moon. The agency started its Lunar Impact Monitoring project to better understand the risks, which continued even after Constellation was cancelled. Ground based michael kors canada outlet fake observations have since catalogued more than 300 flashes from impacts on the lunar surface, caused by objects ranging in size from a golf ball to a bowling ball. Pack your bags One of the brightest flashes came on 17 March 2013, when an object weighing about 40 kilograms blasted an 18 metre wide crater in the lunar surface. NASA's Lunar Reconnaissance Orbiter had photographed the region before, so a team led by Mark Robinson at Arizona State University in Tempe scanned the area again with LRO to see the impact's effects. Speaking at a planetary science meeting in Houston, Texas, this week, Robinson reports that they found 248 fresh "splotches" ranging from 2 to 14 metres in width, which must have been created by ejected material. The debris field is spread within about 30 kilometres of the main crater. Assuming material was ejected at a 45 degree angle, Robinson's team calculates that dirt must have initially been travelling at about 200 meters per second the speed of a shotgun blast.
