NASA's Psyche spacecraft, located nearly 150 million miles from Earth on the way to an unexplored metal asteroid, has stopped firing its engines after detecting a problem in its propulsion system.

NASA published an update Tuesday revealing that the robotic spacecraft shut off its plasma thrusters earlier this month. The news wasn't widely shared until Wednesday, when NASA science chief Nicky Fox posted it on X.

"Engineers with NASA’s Psyche mission are working to determine what caused a recent decrease in fuel pressure in the spacecraft’s propulsion system," the agency said. The spacecraft detected the drop in pressure April 1 inside the line that feeds xenon fuel to the spacecraft's four plasma thrusters.

"It was a very emotional thing, the first time in the 60 years that nobody was actually in the mission control office there at JPL."

For nearly four years, NASA's Perseverance rover has journeyed across an unexplored patch of land on Mars—once home to an ancient river delta—and collected a slew of rock samples sealed inside cigar-sized titanium tubes.

These tubes might contain tantalizing clues about past life on Mars, but NASA's ever-changing plans to bring them back to Earth are still unclear.

On Tuesday, NASA officials presented two options for retrieving and returning the samples gathered by the Perseverance rover. One alternative involves a conventional architecture reminiscent of past NASA Mars missions, relying on the "sky crane" landing system demonstrated on the agency's two most recent Mars rovers. The other option would be to outsource the lander to the space industry.
