According to a new inspector general report, a long delayed and significantly overbudget NASA satellite refueling mission, dubbed OSAM-1 and first proposed around 2010, will experience more delays and further budget overruns in order to get it off the ground by 2026, at the earliest.
A NASA plan to robotically repair and refuel satellites in orbit is way behind schedule and well over budget, says NASA’s Office of the Inspector General (OIG), with most of the blame falling on space tech contractor Maxar.
Maxar, one of the largest private businesses working on NASA’s On-Orbit Servicing, Assembly, and Manufacturing mission (OSAM-1), has been involved in the project since 2016, when the space agency’s idea was smaller in scope and known as Restore-L. According to the OIG, Maxar is two years behind schedule on delivering the the project’s spacecraft bus and its Space Infrastructure Dexterous Robot (SPIDER) robotic arm, and it’s unlikely OSAM-1 will come in under its $2.05 billion budget nor meet the December 2026 launch date NASA committed to in 2022. The bus is the main craft framework, and its attached SPIDER will hopefully repair and refuel satellites in orbit, once it all gets off the ground and works.
NASA isn’t without blame for the delays, the OIG said, but Goddard Space Flight Center’s (the NASA facility where the project is being managed) “struggle with development of several key components of the servicing payload” wasn’t the main issue. “We found that project cost increases and schedule delays were primarily due to the poor performance of Maxar … and its inability to provide the spacecraft bus and SPIDER in accordance with contract requirements,” inspectors concluded in their report.
The plan has always been to refuel the Landsat-7 spacecraft in order to demonstrate robotic in-space servicing of satellites. When first proposed, the idea was untested, and the project was intended to get this industry off the ground. Since then however Northrop Grumman’s MEV servicing robot satellite has leap-frogged NASA to twice reactivate two geosynchronous satellites. At the same time, at least a half dozen other private startups have now done robotic rendezvous and docking demos in orbit, and have actual contracts for their own servicing missions.
Moreover, all the private missions have concepts that are far simplier and cheaper than NASA’s. Rather pump fuel into the defunct satellite’s tanks, the MEV simply docks with the satellite using its now useless main engine nozzle, and once attached becomes a service module with its own fuel and engines to orient and move the satellite. The other servicing startups are doing similar things. No need to develop complex robot arms and fueling systems.
In other words, private industry can learn little from this NASA’s mission. By the time it launches the industry will likely be able to run rings around it. It has become a waste of money that should be shut down, now.
