Northrop Grumman dicit:

SpaceLogistics LLC, a Northrop Grumman Company, has partnered with DARPA on the agency’s Robotic Servicing of Geosynchronous Satellites (RSGS) program.

The groundbreaking mission features the first-ever commercial robotic servicing spacecraft, known as the Mission Robotic Vehicle (MRV), and aims to expand the market for satellite servicing with advanced robotics technology.

The company is also developing Mission Extension Pods (MEPs) to be installed by the MRV. The new pods act in place of the propulsion system of aging satellites and provide six years of life extension.

Lockheed Martin dicit:

Protecting a Mars Rover against the extremes of space travel is critical to the success of any mission. At Lockheed Martin, we’ve built aeroshells to protect all 10 of NASA’s Mars-bound landers and rovers.

For NASA’s latest mission — Mars 2020, which includes the Perseverance rover and Ingenuity helicopter — we built the protective aeroshell and helicopter delivery system. Mars 2020 will attempt the most challenging entry, descent and landing (EDL) sequences ever at Mars. The rover will touch down in the treacherous Jezero Crater, a region filled with boulders, rocky cliffs and shifting sand dunes.

The Graphite-Epoxy Motor (GEM) is a series of solid rocket boosters fueled by HTPB and produced by Northrop Grumman Innovation Systems with a carbon-fiber-reinforced polymer casing. GEM series boosters were previously used on the Delta II, Delta III, and Delta IV. They will fly on the Atlas V and Vulcan.

The GEM-63XL is about 5 feet longer than the regular GEM-63 and will be used on the Vulcan launch vehicle starting in 2021. GEM-63XL offers higher performance at almost half the cost of the AJ-60A boosters currently being used on the Atlas V.

The Exploration Upper Stage (EUS) is being developed as a large second stage for Block 1B of the Space Launch System (SLS), succeeding Block 1’s Interim Cryogenic Propulsion Stage. It will be powered by four RL10-C3 engines burning liquid oxygen and liquid hydrogen to produce a total of 440 kN (99,000 lbf) thrust. As of February 2015, the SLS Block 1B will provide thrust of 105 t (103 long tons; 116 short tons). The EUS is expected to first fly on Artemis IV in 2025.

Copenhagen Suborbitals is the world’s only crewed, crowdfunded space program. In the future, a volunteer astronaut will fly to space on our home-built rocket. We do this on our spare time, all the donations go to paying our workshop rent and buying materials. We are forever thankful to each of our supporters!

SpaceX dicit:

On Wednesday, December 9, Starship serial number 8 (SN8) lifted off from our Cameron County launch pad and successfully ascended, transitioned propellant, and performed its landing flip maneuver with precise flap control to reach its landing point. Low pressure in the fuel header tank during the landing burn led to high touchdown velocity resulting in a hard (and exciting!) landing.
