NASA's Near-Earth Object Surveyor spacecraft has moved a step closer to launch, with its large sunshade undergoing inspection in a clean room at BAE Systems Space & Mission Systems in Boulder, Colorado, in July 2026, according to Mirage News.
The structure, which stands 20 feet (6 meters) tall and is 8 feet (2.4 meters) wide at its base, carries the solar array that will supply all of the mission's electrical power. Its inspection marks one of the later stages of hardware preparation before the spacecraft is assembled and tested as a complete unit.
The sunshade's two flat panels meet at a 23.5-degree angle, a geometry that mirrors the tilt of Earth's axis. Across those panels, 864 interconnected solar cells were installed and tested before the hardware traveled to Colorado. The array can generate as much as 2 kilowatts of power, enough to charge the batteries that run the spacecraft's systems, Mirage News reports.
Why it matters
NEO Surveyor's job is to find some of the most elusive asteroids and comets near Earth, including objects that approach from the direction of the Sun. That region of the sky is difficult for ground-based optical telescopes to search because sunlight overwhelms their view. A space-based infrared telescope, shielded from the Sun's heat and glare, can look into that blind spot.
The sunshade is central to that capability. It is not only the spacecraft's power source but also its protection, and the mission depends on both functions working together. Every later milestone, from instrument integration to launch, rests on this hardware performing as designed.
The program has also drawn attention for its schedule. According to Mirage News, the sunshade structure was delivered to BAE Systems ahead of schedule in May, a contrast to the delays that have affected several other NASA science missions in recent years.
A supply chain spread across the country
The sunshade's journey to Colorado involved several companies and facilities. Applied Aerospace, based in Stockton, California, built the structure itself. SolAero Technologies in Albuquerque, New Mexico, fitted it with its solar cells in January.
Environmental testing followed at a commercial thermal vacuum facility in El Segundo, California, and was completed in March. That kind of testing exposes hardware to the temperature and pressure conditions of space before flight, allowing engineers to catch problems while the equipment is still on the ground. Only after those checks did the sunshade ship to BAE Systems in May.
The July inspection in Boulder was the next formal look at the hardware in its clean room setting, with the sunshade mounted on an assembly ring. Mirage News did not report any findings from that inspection, and NASA has not announced results publicly.
What the mission is built to do
Once in space, NEO Surveyor will scan for asteroids and comets that are hard to detect from Earth, with particular attention to objects that could come from the Sun's direction. Finding them earlier extends the warning time available for tracking and, if necessary, planning a response.
The 2-kilowatt array is modest by the standards of large solar-powered spacecraft, but it is sized for the mission's needs: charging batteries that keep the telescope and its systems running. The angled panels are designed to work alongside the shade itself, which blocks solar heat from the sensitive instrument behind it.
For now, the program's focus is on integration. The inspected sunshade will be joined with the rest of the spacecraft at BAE Systems, and further testing is expected before the mission proceeds toward launch.
