A tiny asteroid explorer that launched on NASA’s moon mission last week still hasn’t phoned home.
Near-Earth Asteroid (NEA) Scout was one of 10 cubesats that hitched a ride to space on NASA’s
mission, which launched on Nov. 16. The spacecraft was designed to sail on sunlight to fly past a small Artemis 1 dubbed 2020 GE about a year from now. But something seems to have gone wrong after the cubesat deployed. asteroid

(SLS) on Nov. 16, the Near-Earth Asteroid Scout (NEA Scout) project team has not yet established communications with the spacecraft,” NASA officials wrote in an emailed statement. “Teams continue working to initiate contact with NEA Scout.” Space Launch System

In particular, NEA Scout personnel are hoping that the spacecraft’s unusual propulsion strategy could help them track down the cubesat. Packed into the small satellite was a reflective, silvery

Had everything gone smoothly, NEA Scout planned to deploy its sail in early December, according to a NASA spokesperson, then use the solar radiation hitting it to reach the asteroid. Instead, despite not having heard from the spacecraft, NASA personnel broadcast a command for “an emergency solar sail deployment” twice on Monday (Nov. 21) in hopes that the highly visible sail could help them find the cubesat.
“If the spacecraft is listening and successfully opened its sail, it could be seen from telescopes on Earth,” NASA officials wrote. “Several ground-based observatories are attempting to look for NEA Scout and share data, which will be invaluable in helping determine the spacecraft’s status.”
NEA Scout isn’t the only cubesat from last week’s Artemis 1 launch to struggle. For example, OMOTENASHI, a tiny Japanese lunar lander,
and another NASA cubesat, LunaH-Map, missed its date with the moon as it flew past the moon on Monday. The agency added the cubesats to Artemis 1 knowing that the small missions carried higher risk than larger spacecraft with more redundancy and durability built into the design. missed a crucial engine fire

If NEA Scout recovers, it will be NASA’s first solar sail to leave Earth’s orbit; if it safely reaches asteroid 2020 GE, the spacecraft will likely make the slowest asteroid flyby to date, and the asteroid will become the smallest any spacecraft has visited,
