Originally planned for 2020, its launch is currently planned for no earlier than 2025. Its first objective would be the complex refueling of Landsat 7, an existing satellite launched in 1999. It would involve grasping the satellite with a mechanical arm, gaining access to the satellite's fuel tank by cutting through insulation and wires and unscrewing a bolt, and then attaching a hose to pump in hydrazine fuel. This would be the first refueling of a satellite in space, and a demonstration of the potential to repair the thousands of satellites in orbit and keep them in operation. Because the satellites now in space were not designed to be serviced, there are significant challenges to doing so successfully.
OSAM-1's second objective would be to deploy a separate robot called SPIDER (Space Infrastructure Dexterous Robot) to build a new structure in space. Using robots to build and assemble new structural components from scratch would be an important step towards a type of space-based construction that has been impossible to date.
The OSAM-1 spacecraft will include :
- two arms to grapple the target satellite
- the attached payload for SPIDER
