NEA Scout will visit an asteroid estimated to be smaller than a school bus – the smallest asteroid ever to be studied by a spacecraft.
HUNTSVILLE, Ala. (NASA PR) — Launching with the Artemis I uncrewed test flight, NASA’s shoebox-size Near-Earth Asteroid Scout will chase down what will become the smallest asteroid ever to be visited by a spacecraft. It will get there by unfurling a solar sail to harness solar radiation for propulsion, making this the agency’s first deep space mission of its kind.
The target is 2020 GE, a near-Earth asteroid (NEA) that is less than 60 feet (18 meters) in size. Asteroids smaller than 330 feet (100 meters) across have never been explored up close before. The spacecraft will use its science camera to get a closer look, measuring the object’s size, shape, rotation, and surface properties while looking for any dust and debris that might surround 2020 GE.
Sailing on sunlight, NEA Scout will capture images of an asteroid for scientific study.
KENNEDY SPACE CENTER, Fla. (NASA PR) — NASA’s Near-Earth Asteroid Scout is tucked away safely inside the agency’s powerful Space Launch System (SLS) rocket at NASA’s Kennedy Space Center in Florida. The solar sailing CubeSat is one of several secondary payloads hitching a ride on Artemis I, the first integrated flight of the agency’s SLS and the Orion spacecraft.
HUNTSVILLE, Ala. (NASA PR) — NASA’s Near-Earth Asteroid Scout, a small satellite designed to study asteroids close to Earth, performed a successful deployment test June 28 of the solar sail that will launch on Exploration Mission-1 (EM-1). The test was performed in an indoor clean room at the NeXolve facility in Huntsville, Alabama.
HUNTSVILLE, Ala. (NASA PR) — NASA’s Near-Earth Asteroid Scout, a small satellite the size of a shoebox, designed to study asteroids close to Earth, performed a full-scale solar sail deployment test at ManTech NeXolve’s facility in Huntsville, Alabama, Sept. 13. The test was performed in an indoor clean room to ensure the deployment mechanism’s functionality after recent environmental testing.
NASA officials have been providing updates this week on agency programs and missions during the 2016 Small Satellite Conference and the CubeSat Workshop that preceded it. I have pulled together summaries of their presentations drawn from Twitter. Information has come from the following Tweeters:
Video Caption: In this time lapse, the Near-Earth Asteroid Scout (NEA Scout) CubeSat team rolls a half-scale prototype of the small satellite’s solar sail in preparation for a deployment test. During its mission, NEA Scout will perform an approximate two-year cruise propelled by the solar sail to a target asteroid. A camera on the CubeSat will capture a series of low (50 cm/pixels) and high resolution (10 cm/pixels) images to determine global shape, spin rate, pole position, regional morphology, regolith properties, spectral class, and for local environment characterization.
