NASA'sPhoenix Mars lander continues its journey to the red planet following its Aug.4, 2007 liftoff, and is checking out its equipment along the way.
All tuckedup inside its protective shell, the lander's Robotic Arm Camera (RAC) snappeda photo of the Robotic Arm Scoop. To capture the image, the spacecraft utilizeda red light-emitting diode (LED) lamp. The picture has been beefed up in falsecolor to better represent what the camera saw.
The camera,scoop and otherinstruments are encased in a protective "biobarrier" to ensure noEarth organisms are carried to Mars and guard against "forwardcontamination" of the red planet.
Once on thesurface of Mars, the Phoenix lander will deploy its robotic arm. The roboticshovel will dig trenches, scoop up icy soil samples and dump them intoinstruments on the lander's deck for chemical analysis, then beam the data backto Earth. Once Phoenix scientists receive the soil specs, they hopeto determine whether or not Mars was--or still is--a place hospitable tomicrobial life.
Images fromthe RAC, one of five imaging devices on the lander, will be the only picturestaken and sent to Earth until Phoenix makes a May 25, 2008 approach and landingon Mars. Additional spacecraft-monitoring images will be taken by the cameralater in the cruise stage to Mars.
