NASA's mission to explore the remains of a dead planet
. The spacecraft is due to launch on Oct. 5, 2023, with the launch window running through to Oct. 25. , NASA revealed that the major problems were with the spacecraft's GNC software, which is crucial for controlling the orientation of the spacecraft as it flies and is used to point the spacecraft's antenna toward Earth to return data and accept commands from mission control. In addition, the GNC software is necessary to aim Psyche's solar electric propulsion system.
The issues weren't fixable in time for a 2022 launch, and with that launch window missed, the spacecraft will have to take an altered path to its metallic destination. The 2022 liftoff would have brought Psyche to its asteroid target in early 2026, but a 2023 launch pushes the craft's arrival to August 2029, NASA officials said in their statement about the delay.
In another tweak to the final plans, NASA's Janus small-satellite mission, which is designed to study a pair of binary asteroid systems, may not be able to hitch a ride to space with Psyche as it would have on a 2022 launch."NASA continues to assess options" for Janus, officials wrote. But NASA's Deep Space Optical Communications may still fly with Psyche in 2023. That ride-along mission is integrated into the asteroid probe and can't be disentangled as easily.
