Northrop Grumman Space Systems

Antares known during early development as Taurus II, is an expendable launch system developed by Orbital Sciences Corporation (now part of Northrop Grumman Innovation Systems after Northrop Grumman acquired Orbital ATK) and the Yuzhnoye Design Bureau to launch the Cygnus spacecraft to the International Space Station as part of NASA's COTS and CRS programs. Able to launch payloads heavier than 5,000 kg (11,000 lb) into low-Earth orbit, Antares is the largest rocket operated by Orbital ATK. Antares launches from the Mid-Atlantic Regional Spaceport and made its inaugural flight on April 21, 2013.

The Apollo lunar module (LM) ascent stage contained the crew cabin with instrument panels and flight controls. It contained its own Ascent Propulsion System (APS) engine and two hypergolic propellant tanks for return to lunar orbit and rendezvous with the Apollo command and service module.

STP-S29A is a mission under the U.S. Department of Defense's Space Test Program (STP) that will deliver technology demonstrations to orbit and contribute to future space system development, with this launch delivering up to 200 kg of STP cubesats to Low Earth Orbit.

The main payload will be STPSat-7, an ESPA class satellite based on the Aegis Aerospace M-1 satellite bus used on the STPSat-4 mission for hosting research and technology demonstration payloads for the Department of Defense (DoD). One of the payload is U.S. Naval Research Laboratory's (NRL) Lightsheet Anomaly Resolution and Debris Observation (LARADO) instrument, used to detect and characterize lethal non-trackable orbital debris with lasers in orbit.
