Northrop Grumman is developing the next generation of the GEM family of strap-on boosters to support intermediate- and large-class space launch vehicles. These boosters build on the company’s extensive history of the successful GEM 40, GEM 46, and GEM 60 motors. The GEM 63 and GEM 63XL motors will be capable of supporting national security, science and commercial payloads. The company is leveraging its industry-leading expertise in composite large solid rocket motor development and manufacturing to provide customers with a cost-effective, reliable, flexible, and on-time system, starting in 2019 for United Launch Alliance’s Atlas and Vulcan launch vehicles.

Exploration Ground Systems continued to make sure the mobile launcher is ready for Artemis I with a multi-arm swing test on Friday, October 4, 2019 at Launch Pad 39B at Kennedy Space Center in Florida. The Umbilical Arm Simultaneous Retract Test included retraction of the connections that will provide fuel, coolant and communications to the Space Launch System rocket up until launch. The umbilicals tested included the Interim Cryogenic Propulsion Stage Umbilical (ICPSU), the Core Stage Forward Skirt Umbilical (CSFSU) and the Core Stage Intertank Umbilical (CSIU).

European Organisation of Telecommunications by Satellite S.A. (EUTELSAT) is a European satellite operator. Providing coverage over the entire European continent, the Middle East, Africa, Asia and the Americas, it is the world’s third largest satellite operator in terms of revenues. Eutelsat’s satellites are used for broadcasting nearly 7,000 television stations, of which 1,400 are in HD, and 1,100 radio stations to over 274 million cable and satellite homes. They also serve requirements for TV contribution services, corporate networks, mobile communications, Internet backbone connectivity and broadband access for terrestrial, maritime and in-flight applications.

The Mission Extension Vehicle (MEV) is a spacecraft concept proposed by ViviSat. ViviSat was a 50/50 joint venture of aerospace firms U.S. Space and ATK created in 2010 for the purpose of designing, producing and operating the MEV-program. The purpose of the MEV-spacecraft is to operate as a small-scale in-space satellite-refueling spacecraft. Since the original conception of the MEV-program by the ViviSat-company, the Vivisat-venture has been shut down and the company dissolved by ATK (one of the partners in Vivisat) in April of 2016. The MEV-program has continued as a solo-project of ATK. ATK has been since purchased by Northrop Grumman in 2018, and is now Northrop Grumman Innovation Systems. The MEV-program continues under Northrop Grumman.

The SpaceX CrewDragon spacecraft parachutes successfully deploy during the latest development test. This test simulated a pad abort, where the vehicle is tumbling at low altitude before parachute deploy, validating SpaceX’s parachute models and margins. As a part of NASA’s Commercial Crew Program, SpaceX has been developing and testing the Crew Dragon parachute system, which is comprised of two drogue parachutes and four main ring-sail parachutes—the same type of parachutes that have been commonly and successfully used for human spaceflight in the past.

A terrain relative navigation system developed by Draper of Cambridge, Massachusetts, will be tested on a Masten Space Systems Xodiac rocket. The flight is made possible with support from NASA’s Flight Opportunities and Game Changing Development programs. The Draper technology will eventually be ported directly into a NASA-developed descent landing computer for additional testing.

This video shows one of a series of tether tests of the navigation system mounted on the rocket. Tether tests like this ensure the rocket and navigation technology are communicating before the actual suborbital launch and landing.

NASA and commercial partners are relying on the most advanced technology to upgrade navigation for future robotic and crewed missions to the Moon. The agency is developing a suite of precision landing technologies for possible use on future commercial lunar landers.
