NASA has canceled an over-budget, behind-schedule mission to demonstrate robotic satellite servicing technology in orbit, pulling the plug on a project that has cost $1.5 billion and probably would have cost nearly $1 billion more to get to the launch pad.
The On-orbit Servicing, Assembly, and Manufacturing 1 mission, known as OSAM-1, would have grappled an aging Landsat satellite in orbit and attempted to refuel it, while also demonstrating how a robotic arm could construct an antenna in space. The spacecraft for
