NASA Solar Sail Asteroid Mission Readies for Launch on Artemis I
NASA’s Near-Earth Asteroid Scout is stashed securely inside the firm’s effective Space Launch System (SLS) rocket at NASA’s Kennedy Space Center in Florida. The solar cruising CubeSat is among a number of secondary payloads riding on Artemis I, the very first incorporated flight of the firm’s SLS and the Orion spacecraft.
NEA Scout, a little spacecraft approximately the size of a big shoebox, has actually been packaged into a dispenser and connected to the adapter ring that links the SLS rocket and Orion spacecraft. The Artemis I objective will be an uncrewed flight test. It likewise uses deep area transport for a number of CubeSats, making it possible for chances for little spacecraft like NEA Scout to reach the Moon and beyond as part of the Artemis program.
“NEA Scout will be America’s first interplanetary mission using solar sail propulsion,” stated Les Johnson, primary innovation detective for the objective at NASA’s Marshall Space Flight Center. “There have been several sail tests in Earth orbit, and we are now ready to show we can use this new type of spacecraft propulsion to go new places and perform important science.”

The CubeSat will utilize stainless-steel alloy booms to release an aluminum-coated plastic movie cruise – thinner than a human hair and about the size of a racquetball court. The large-area sail will produce thrust by showing sunshine. Energetic particles of sunshine, called photons, bounce off the solar sail to provide it a mild yet continuous push. Over time, this continuous thrust can speed up the spacecraft to extremely high speeds, enabling it to browse through area and reach its target asteroid.
“This type of propulsion is especially useful for small, lightweight spacecraft that cannot carry large amounts of conventional rocket propellant,” Johnson stated.
NEA Scout is likewise a stepping-stone to another just recently picked NASA solar sail objective, Solar Cruiser, which will utilize a sail 16 times bigger when it flies in 2025.

Sailing on sunshine, NEA Scout will start an approximate two-year journey to zip a near-Earth asteroid. Once it reaches its location, the spacecraft will utilize a science-grade electronic camera to catch pictures of the asteroid – to less than half an inch (10 centimeters) per pixel – which researchers will then study to even more our understanding of these little however crucial planetary system next-door neighbors. High-resolution imaging is enabled thanks to the low-velocity flyby (less than 100 feet, or 30 meters, per second) allowed by the solar sail.
The information acquired will assist researchers comprehend a smaller sized class of asteroids – those determining less than 100 meters (330 feet) throughout – that have actually never ever been checked out by spacecraft.
“The images gathered by NEA Scout will provide critical information on the asteroid’s physical properties such as orbit, shape, volume, rotation, the dust and debris field surrounding it, plus its surface properties,” stated Julie Castillo-Rogez, the objective’s primary science detective at NASA’s Jet Propulsion Laboratory.
Near-Earth asteroids are likewise crucial locations for expedition, in situ resource usage, and clinical research study. In the previous years, detections of near-Earth asteroids have actually gradually increased and are anticipated to grow, providing broadened chances as expedition locations.
“Despite their size, some of these small asteroids could pose a threat to Earth,” Dr. Jim Stott, NEA Scout innovation task supervisor, stated. “Understanding their properties could help us develop strategies for reducing the potential damage caused in the event of an impact.”
Scientists will utilize this information to identify what is needed to lower threat, boost efficiency, and enhance the style and operations of robotic and human area expedition, included Castillo-Rogez.
NEA Scout is established under NASA’s Advanced Exploration Systems department. The CubeSat is developed and established by NASA Marshall in Huntsville, Alabama, and JPL in Southern California.
