The spacecraft, constructed by Maxar House Methods, will function its electrical thrusters for the equal of three months between now and November to maintain the mission on monitor for arrival at asteroid Psyche in 2029.
“By means of complete testing and evaluation, the group narrowed down the potential causes to a valve which will have malfunctioned within the main line,” NASA stated in an announcement Friday. “The swap to the similar backup propellant line in late Could restored full performance to the propulsion system.”
The following waypoint on Psyche’s voyage can be a flyby of Mars in Could 2026. Officers anticipate Psyche to maintain that date, which is important for utilizing Mars’ gravity to slingshot the spacecraft deeper into the Photo voltaic System, ultimately reaching the asteroid belt about 4 years from now.

At Psyche, the spacecraft will enter orbit and progressively transfer nearer to the asteroid, utilizing a set of sensors to map its floor, measure its form, mass, and gravity area, and decide its elemental composition. Observations by telescopes recommend Psyche is roughly 140 miles (226 kilometers) in diameter, or concerning the width of Massachusetts. However it’s doubtless not spherical in form. Scientists describe its form as extra akin to a potato.
Potatoes are available in numerous shapes, and researchers will not know precisely what Psyche seems to be like till NASA’s asteroid explorer arrives in 2029. Psyche would be the first metallic, or M-type, asteroid visited by any spacecraft, and scientists are keen to review an object that is largely fabricated from metals—in all probability iron, nickel, and maybe some rarer parts— as an alternative of rocky minerals.
With the Psyche spacecraft’s plasma thrusters again in motion, these targets of NASA’s billion-dollar science mission stay achievable.
“The mission group’s dedication and systematic strategy to this investigation exemplifies the most effective of NASA engineering,” stated Bob Mase, Psyche challenge supervisor at JPL, in an announcement. “Their thorough prognosis and restoration, utilizing the backup system, demonstrates the worth of sturdy spacecraft design and distinctive teamwork.”
However there’s nonetheless a lingering concern no matter downside precipitated the valve to malfunction within the main gas line may additionally ultimately have an effect on the identical form of valve within the backup line.
“We’re doing a variety of good proactive work round that doable concern,” wrote Lindy Elkins-Tanton, Psyche’s principal investigator at Arizona State College, in a submit on X.
