HTTP:: NASA Identifies LCROSS Impact Plume
--------
Over the past week, debate has raged on whether or not scientific observations of the plume emitted by the Centaurus upper rocket stage upon slamming into the Moon last Friday will be visible or not. Some have argued that the calculations on which the mission was founded were flawed, while others said that the instruments aboard the $79-million Lunar CRater Observation and Sensing Satellite (LCROSS) surely must have picked something up, and finding it was just a question of browsing available data. The latter group appears to have been correct in their arguments. Officials at the American space agency have just announced that the first images showing the debris plume ejected by the impacting upper stage have been found, and are currently being analyzed. The faint signature of the 3.7- to 5-mile (6- to 8-kilometer) tall ejecta has been detected by both of the spacecraft's mid-infrared (MIR) thermal cameras, its ultraviolet/visible and near infra-red spectrometer, as well a!
s its Visible Light Camera, Space reports. “The images of the floor of Cabeus are exciting. Being able to image the Centaur crater helps us reconstruct the impact process, which in turn helps us understand the observations of the flash and ejecta plume. Within the range of model predictions we made, the ejecta brightness appears to be at th...
