Record-Setting Launch Visible from U.S. East Coast Tonight

Tonight, the U.S. Air Force will catapult 29 satellites into Earth orbit from NASA's Wallops Flight Facility in Virginia. Weather permitting, the record-setting launch of the ORS-3 mission will be visible from much of America's Eastern Seaboard. The 105-minute launch window will open at 7:30 p.m. ET.

Writes SPACE.com's Mike Wall:

The Minotaur 1 will be hauling a cornucopia of 29 satellites tonight — the most ever lofted in a single launch, mission officials said.

ORS-3's primary payload is the Air Force's STPSat-3 spacecraft, which was built as part of a military program designed to reduce the time and cost required to get satellites to the launchpad. STPSat-3 itself carries five different experiments and sensors that will measure various aspects of the space environment.

The other 28 satellites? Cubesats.
