CAPE CANAVERAL, Fla. (AP) — NASA's Jupiter-circling spacecraft is stuck making long laps around the gas giant because of sticky valves.
It currently takes Juno 53 days to fly around the solar system's biggest planet. That's almost four times longer than the intended 14-day orbit.
After repeated delays, NASA decided late last week to scrap an engine firing that would have shortened the orbit. Officials said the maneuver is too risky because of the valve problem.
