mission patch the near earth asteroid scout nea scout was a mission by nasa to develop a controllable low cost cubesat solar sail spacecraft capable of encountering near earth asteroids nea 5 6 nea scout was one of ten cubesats launched into a heliocentric orbit on artemis 1 the maiden flight of the space launch system on 16 november 2022 3 7 the target for the mission was asteroid 2020 ge 8 but this could have changed based on launch date or other factors 9 after deployment nea scout was to perform a series of lunar flybys to achieve optimum departure trajectory before beginning its two year long cruise no contact with the spacecraft was ever made and the mission was lost 10 overview edit the mission was funded by nasa s human exploration and operations mission directorate near earth asteroids neas are of interest to science and as nasa continues to refine its plans to possibly explore these small objects with human explorers initial reconnaissance with inexpensive robotic precursors is necessary to minimize risks and inform the required instruments for future reconnaissance missions the characterization of neas that are larger than 20 m 66 ft in diameter is also of great relevance to plan mitigation strategies for planetary defense 6 nasa s marshall space flight center msfc and jet propulsion laboratory jpl jointly developed this mission with support from nasa s goddard space flight center gsfc lyndon b johnson space center jsc langley research center lrc and nasa headquarters 5 the principal investigator science was julie castillo rogez from nasa s jpl the principal investigator was les johnson from nasa msfc goal edit the nasa near earth asteroid nea scout mission was going to demonstrate the capability of an extremely small spacecraft propelled by a solar sail to perform reconnaissance of an asteroid at low cost the goal was to develop a capability that would close knowledge gaps at a near earth asteroid in the 1 100 m range 6 11 12 neas in the 1 100 m range are poorly characterized due to the challenges that come with detecting observing and tracking these for extended periods of time it has been thought that objects in the 1 100 m size range are fragments of bigger objects however it has also been suggested that these objects could actually be rubble piles 6 the mission researchers argued that characterization of neas that are larger than 20 m in diameter is also of great relevance to inform mitigation strategies for planetary defense target edit the planned target was near earth asteroid 2020 ge 8 the asteroid made a close approach to earth in september 2023 of around 5 7 million kilometres which was when nea scout was scheduled to make its flyby 8 the spacecraft would have approached the asteroid at less than a mile distant and make the slowest flyby of any asteroid by any spacecraft at less than 30 m s a 14 megapixel camera the mission s sole instrument was going to image the object at very high resolutions of up to 10 cm pixel 2020 ge is no more than 18 meters across and would have been the smallest object yet explored by spacecraft 8 status edit as of 17 november 2022 nea scout was one of two out of the ten cubesats released by artemis i whose status remained unknown 13 communications with the spacecraft had not been established as of 18 november 2022 two days after launch 14 as of december 2022 nea scout was considered lost after deployment of its solar sail had failed and contact could not be established 10 payload edit observations would have been achieved using a cubesat performing a close 10 km flyby equipped with a high resolution science grade monochromatic camera to measure the physical properties of a near earth object the camera was a custom jpl design 15 the electronics were based on the context camera design for the orbiting carbon observatory 3 oco3 instrument 16 with a custom firmware a ruggedized commercial lens and a fully re designed enclosure 15 the measurements to be addressed included target s accurate positioning position and prediction rotation rate and pole position mass density mapping of particles and debris field in target vicinity albedo and asteroid spectral type surface morphologies and properties and regolith properties 6 the mission used nasa s deep space network as the primary component for communications and tracking 6 design edit components of the nea scout the spacecraft architecture first presented in 2014 was based on a 6 unit cubesat with a stowed envelope slightly larger than 10 20 30 cm a mass of 14 kg 31 lb 1 cold gas thruster system 17 and was primarily based on the use of commercial off the shelf parts 6 while it is possible for a 6u cubesat to reach an nea with conventional chemical propulsion both the number of targets and the launch window would be tightly constrained by utilizing solar sail propulsion intercepting a large number of targets in any launch window is made possible 1 the mission duration was estimated at 2 5 years 2 after deployment in cislunar space nea scout was intended to deploy its solar panels and antenna following a lunar flyby the solar sail would have deployed and spacecraft checkout would have begun nea scout would then have performed a series of lunar flybys to achieve optimum departure trajectory before beginning its 2 0 2 5 year long cruise to the asteroid 2020 ge 12 sail four 6 8 m booms were designed to deploy the single 85 m 2 aluminized polyimide solar sail which is 2 5 μm thick the sail deployment mechanism was a modification of those of nanosail and the planetary society s lightsail 2 spacecraft 1 12 the deployment time for the full sail was planned to be approximately 30 minutes avionics the avionics module accommodated the printed circuit boards for telecommunications power distribution unit command and data handling system sun sensors and a miniaturized star tracker this module also included reaction wheels lithium batteries and a camera 6 the solar sail spacecraft attitude control system consisted of three actuating subsystems a reaction wheel control system a reaction control system and an adjustable mass translator system 18 propulsion the cold gas propulsion system was situated below the solar sail and provides detumbling initial impulsive maneuvers required for lunar assisted escape trajectories and momentum management 17 communications the spacecraft used the iris transponder for communications in the x band 6 power photovoltaic solar panels with rechargeable batteries animation of nea scout s planned trajectory around the sun around the earth
