OSAM-1

Last updated

OSAM-1 (On-orbit Servicing, Assembly, and Manufacturing 1) was a 2016-2024 conceptual NASA mission and spacecraft designed to test on-orbit refueling of satellites. The program was cancelled in 2024, two years ahead of its planned launch date. It was initially known as Restore-L. [1] [2] [3]

Originally scheduled to launch in 2020, [4] its launch at the time of cancellation was planned for no earlier than 2026. [5] The primary objective of the concept mission and spacecraft was the complex refueling of Landsat 7, a satellite launched in 1999, that was not designed for on-orbit servicing. This would have involved 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. At the time the mission was conceived, it was expected to be the first refueling of a satellite in space, and a demonstration of the potential to repair some of the thousands of active satellites in orbit and keep them in operation for a longer time. [1] Because the satellites now in space were not designed to be serviced, there are significant challenges to doing so successfully. [1] [2]

OSAM-1's second objective, added in 2020, was 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 had been impossible to date. [1]

Description

The OSAM-1 spacecraft was to include:

History

In 2016, NASA's Restore-L satellite was intended to refuel Landsat 7. [4]

In 2020, SPIDER was added and the name was changed from Restore-L to OSAM-1.

In Feb 2022, OSAM-1 passed its Critical Design Review. [6]

On 04 Sept 2023, NASA notified Congress of their intent to cancel OSAM-1. [7]

On 20 Sept 2023 the satellite bus arrived at NASA Goddard from Maxar. [8]

On 1 March 2024, NASA announced that OSAM-1 had been cancelled due to "continued technical, cost, and schedule challenges, and a broader community evolution away from refueling unprepared spacecraft." [9]

Cost & legacy

OSAM-1 was funded by NASA’s Space Technology Mission Directorate through its Technology Demonstration Missions program. [10]

At cancellation in 2024, about $2 billion had been invested in the project. [11]

Progression

A subsequent mission, OSAM-2, would have also had two robotic arms. [12] OSAM-2 would have used ModuLink software which is based on xLink. [12] In 2023, NASA decided to conclude the OSAM-2 project without proceeding to a flight demonstration. [13]
