Aerojet Rocketdyne has secured a contract to provide the Department of Energy with two units of thermoelectric generators designed for deep space missions. The company said Friday it will fabricate, deliver and test a couple of Multi-Mission Radioisotope Thermoelectric Generators that would support possible missions to explore Saturn’s moon Titan and Neptune’s largest moon Triton. 

Aerojet Rocketdyne has wrapped up the construction of an oxygen-rich staged combustion kerosene engine funded by the U.S. Air Force, and is now looking to test its first rocket motor, SpaceNews reported Tuesday.

NASA is scheduled to conduct a hot fire test for four engines built by Aerojet Rocketdyne for the Space Launch System Jan. 17 as part of a series of “Green Run” trials for the vehicle's core stage.

James Taiclet, president and CEO of Lockheed Martin, said acquiring Aerojet Rocketdyne will bring in propulsion systems for potential integration with Lockheed-built missile and rocket offerings, Via Satellite reported Monday. Taiclet told analysts Monday during a conference call he expects the transaction to support upfront design, production planning and engineering integration efforts at the Bethesda, Maryland-based aerospace and defense company.

Aerojet Rocketdyne and the U.S. Air Force Research Laboratory conducted hot-fire tests for an 18-foot air-breathing hypersonic engine built in support of the Medium Scale Critical Components initiative.

Aerojet Rocketdyne has hit a new milestone for its solid rocket flight motor with the delivery of the 5,000th unit to power Raytheon Technologies' Stinger missile system.
