NASA had an ambitious $2 billion plan to refuel satellites in orbit using robotic arms. A decade later, it's in shambles.

• For nearly a decade, NASA has been building a robotic arm that can refuel old satellites in space.
• But it killed the project on Friday amid budget issues, delays, and technical flops.
• In development since 2015, its budget grew to $2.05 billion by 2022, a scathing audit report said.

The National Aeronautics and Space Administration (NASA) is giving up its mission to refuel old satellites in orbit, putting an end to an ambitious $2 billion project plagued by delays and technical setbacks.

The administration said on Friday that it's discontinuing the effort after an independent review, citing "continued technical, cost, and schedule challenges."
