NASA is one step closer to robotically refueling a satellite and demonstrating in-space assembly and manufacturing thanks to the completion of an important milestone.

In April 2021, NASA and Maxar Technologies successfully completed the On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1) mission spacecraft accommodation Critical Design Review (CDR). This milestone demonstrates that the maturity of the design for the OSAM-1 spacecraft bus is appropriate to support proceeding with fabrication, assembly, integration, and testing.

OSAM-1 will, for the first time ever, robotically refuel a U.S. government satellite not designed to be serviced. The spacecraft will consist of a servicing payload, provided by NASA's Goddard Space Flight Center in Greenbelt, Maryland, with two robotic arms that will be attached to the spacecraft bus.

The bus will also incorporate a payload called Space Infrastructure Dexterous Robot (SPIDER) that will demonstrate in-space assembly and manufacturing. SPIDER will use a third robotic arm to assemble a communications antenna and an element called MakerSat built by Tethers Unlimited to manufacture a beam. The spacecraft bus and SPIDER are being built by Maxar Technologies.

This image, taken by Maxar in their Palo Alto, California, facility, features the OSAM-1 spacecraft bus under development. The 14-foot-tall bus will provide OSAM-1 with power and the ability to maneuver in orbit. To make these maneuvers possible, inside the main cylinder are two large bi-propellant tanks, and the upper and lower deck of the spacecraft feature thrusters. The two silver spheres are filled with mono-propellant fuel that will be used to provide OSAM-1's target client satellite, Landsat 7, with more fuel to demonstrate that robotically refueling a satellite is possible.

Upon completion of the OSAM-1 spacecraft bus and related testing at Maxar's facilities in mid-2022, it will be sent to Goddard. NASA will complete the integration and testing of the OSAM-1 components, including the spacecraft bus, servicing payload, and SPIDER, in preparation for launch.

OSAM-1 is funded by NASA's Space Technology Mission Directorate through its Technology Demonstration Missions program.

Hot and cold space radio testing
Paris (ESA) Apr 29, 2021
ESA's newest radio-frequency test facility allows direct measurement of antenna systems in the very vacuum conditions and thermal extremes they will work in, including the chill of deep space. It will soon be put to work testing the Juice mission's radiometer - destined to probe the thin atmospheres of Jupiter's largest moons. The recently completed facility is called the Low-temperature Near-field Terahertz Chamber , or Lorentz. Based at ESTEC in the Netherlands, it can test high-frequency RF sys ... read more
