San Luis Obispo, Calif. -- 101116-F-8290C-045 -- Students at California Polytechnic State University Cal Poly prepare to integrate miniature research satellites called CubeSats into a Poly Picosatellite Orbital Deployer PPOD container. The PPOD and CubeSat Project were developed by Cal Poly and Stanford University’s Space Systems Development Lab for use on NASA’s Educational Launch of Nanosatellite ELaNa missions. Each CubeSat measures about 4-inches cubed and is about the same volume as a quart. The CubeSats weigh about 2.2 pounds, must conform to standard aerospace materials and must operate without propulsion. The satellites are being prepared to launch with NASA's Glory spacecraft aboard an Orbital Sciences Corp. Taurus XL rocket, targeted to lift off Feb. 23, 2011, from Vandenberg's Space Launch Complex 576-E. Glory is scheduled to collect data on the properties of aerosols and black carbon from its place in low Earth orbit.

Next, Stage 0 will be hoisted into its launch position. As part of the four-stage Taurus XL rocket that will carry NASA's Glory spacecraft into low Earth orbit, stages 1, 2 and 3 will join Stage 0 at the launch pad about a week later. Once Glory reaches orbit, it will collect data on the properties of aerosols and black carbon. It also will help scientists understand how the sun's irradiance affects Earth's climate. Launch is scheduled for 5:09 a.m. EST Feb. 23. For information, visit www.nasa.gov/glory. Photo credit: NASA/Randy Beaudoin, VAFB KSC-2011-1105
