NASA says an Aug. 14 test of an engine for the Space Launch System was a success despite an unspecified “facility issue” that caused the test to end early.
A government-industry team announced July 10 they successfully completed a series of 10 test firings over 10 days of a shuttle-era engine intended for use on a reusable suborbital spaceplane.
A space shuttle-era main engine is undergoing a series of daily test firings to demonstrate its suitability for use on a reusable spaceplane under development.
In the wake of Northrop-Orbital merger, Aerojet’s solid rocket engine business teetering on the brink
There are now technically two companies that still manufacture large solid rockets for military ICBMs. The industry is poised to become a monopoly, however, as Aerojet’s large solid rocket motor business is on not-so-solid ground.
Aerojet Rocketdyne and the U.S. Air Force have revised an existing agreement supporting development of a new large rocket engine to include work on an updated version of an upper stage engine.
United Launch Alliance has picked Aerojet Rocketdyne’s RL10 engine to power the upper stage of its next-generation Vulcan rocket, the second such contract Aerojet has secured in as many months.
The U.S. Air Force and Aerojet Rocketdyne are working to revise an agreement to support development of the company's AR1 rocket engine, as questions continue about the engine's long-term future.
Aerojet Rocketdyne’s success in developing AR1, an engine designed to replace Russian-made RD-180 engines on United Launch Alliance rockets, hinges in part on its use of Mondaloy, a nickel-based superalloy invented in the 1990s by metallurgists Monica Jacinto.
As the National Security Space community implements resiliency and disaggregation, and as we take advantage of the rapid acceleration of technology, it appears we are moving toward smaller, shorter life, and more numerous satellite programs.
The chief executive of United Launch Alliance said Nov. 9 that he doesn’t feel any urgency to select a main engine for his company’s next-generation Vulcan rocket, despite an impending deadline for an Air Force launch competition.
Research and development (R&D) costs for the AR1 rocket from the program’s inception through June 30 have reached about $228 million, according to recent Security Exchange Commission (SEC) filings by Aerojet Rocketdyne, the engine's manufacturer.
