WASHINGTON (NASA PR) — NASA has selected 11 small research satellites from seven states and Puerto Rico to fly as auxiliary payloads aboard space missions planned to launch in 2019, 2020, and 2021.

The selections are part of the ninth round of the NASA CubeSat Launch Initiative. CubeSats are a type of spacecraft called nanosatellites, often measuring about four inches on each side and weighing less than three pounds, with a volume of about one quart. CubeSats are built using these standard dimensions as Units or “U”, and are classified as 1U, 2U, 3U, or 6U in total size.

ANN ARBOR, Mich. (University of Michigan PR) — An advanced space engine in the running to propel humans to Mars has broken the records for operating current, power and thrust for a device of its kind, known as a Hall thruster.

The development of the thruster was led by Alec Gallimore, University of Michigan professor of aerospace engineering and the Robert J. Vlasic Dean of Engineering.

SAN ANTONIO (SwRI PR) — NASA’s Cyclone Global Navigation Satellite System (CYGNSS) mission took another major step last month as the eight CYGNSS microsatellites successfully completed functional and environmental testing of their systems and software. The mission is on track for launch in late 2016.

CYGNSS will probe the inner core of hurricanes in greater detail to better understand their rapid intensification.

Northrop Grumman Developing Solar Electric Propulsion Under NASA Contract

REDONDO BEACH, Calif., Jan. 31, 2012 (NGC PR) — Northrop Grumman Corporation was recently awarded a contract to study high-power solar electric propulsion flight system technology for NASA deep space and human exploration missions.

“In collaboration with our partners, we are working on alternatives to the typical solar array approach,” said Jim Munger, solar electric propulsion program manager, Northrop Grumman Aerospace Systems. “Our concept will be scalable to 300 kilowatts and beyond and have the potential for reducing the cost and complexity of high-power requirements.”
