Four student built cubesats launched on Atlas V

The Atlas V that launched last night carried 12 cubesats in addition to its primary spysat payload and four of these cubesats were built by students:

NASA Initiative Helps Launch Student-Built Satellites

With help from NASA, four student-built CubeSat research satellites launched into space Friday from the California coast as part of the agency’s CubeSat Launch Initiative.

The CubeSats were included as auxiliary payloads aboard a United Launch Alliance Atlas V rocket that lifted off from Vandenberg Air Force Base in Lompoc, Calif., at 11:14 p.m. PST Dec. 5 (2:14 a.m. EST Dec. 6) carrying the National Reconnaissance Office’s NROL-39 satellite. The CubeSats, are a part of the Educational Launch of Nanosatellite (ElaNa) mission, NASA’s fifth ElaNa mission launch into space. The miniature satellites deployed from their protective cases into Earth orbit about three hours after liftoff.

The teams responsible for the satellites are beginning to receive signals as the CubeSats come online. Although it could take several days for full confirmation, all of the spacecraft appear to be doing well in their new home in low-Earth orbit.

“This was another great moment for the ELaNa mission and the CubeSat community,” said Jason Crusan, director of NASA’s Advanced Exploration Systems Division, which oversees the CubeSat Launch Initiative. “With each successful mission, we are demonstrating that frequent access to space provides a great opportunity for NASA to gain engineering results at a low cost while affording students real-world exposure to spaceflight.”

The CubeSats were prepared by NASA’s Jet Propulsion Laboratory in Pasadena, Calif., and students at Medgar Evers College at the City University of New York; Montana State University in Bozeman; and the University of Michigan at Ann Arbor in collaboration with the University of New Hampshire in Durham.

CubeSats are a class of research spacecraft called nanosatellites. The cube-shaped satellites measure about 4 inches on each side, have a volume of about 1 quart and weigh less than 3 pounds. CubeSat research addresses science, exploration, technology development, education or space missions.

ELaNa missions, conducted under NASA’s CubeSat Launch Initiative, give students, teachers and faculty hands-on experience developing flight hardware by providing access to a low-cost avenue for research. Since its inception in 2010, the CubeSat Launch Initiative has selected more than 90 CubeSats from primarily educational and government institutions around the United States. NASA chose these miniature satellites from respondents to public announcements for the agency’s CubeSat Launch Initiative. NASA will announce another call for proposals in August.
