Andrews Space has completed delivery of four Cargo Module Power Units (CMPUs) that will supply power to payloads aboard Orbital's Cygnus? spacecraft.

Andrews was contracted by Orbital Sciences in September 2010 to deliver a total of four flight-qualified CMPUs, which power mid-deck locker payloads destined for the International Space Station (ISS) aboard the Cygnus cargo vehicle.

Under a $1.9 billion Commercial Resupply Services (CRS) contract with NASA, Orbital is scheduled to fly eight missions between 2012 and 2015, delivering 20,000 kilograms of cargo to the ISS.

The recently delivered CMPUs will provide up to 150 Watts of 28VDC payload power and will be used on the first CRS mission scheduled for early 2012.

"It has been a pleasure working with Orbital on this important program," said Krissa Watry, CMPU Program Manager at Andrews Space.

"Delivery of the CMPU marks a major milestone for Andrews and sets a new standard for our spaceflight hardware programs."

The CMPU was on critical path from day one and the Andrews team went from contract award to first unit delivery in less than 10 months.
