Mission teams have successfully integrated solar arrays onto the NEO Surveyor spacecraft sunshade. This milestone follows the completion of functional and performance testing for the solar power system.
Why it matters
The sunshade is critical for maintaining the telescope at the extremely low temperatures necessary for infrared observation. It enables the mission to gather data on potentially hazardous near-Earth objects.
The sunshade stands 20 feet tall with an 8-foot base and features 864 solar cells angled at 23.5 degrees to generate 2 kilowatts of power. The telescope utilizes a 20-inch aperture and 16-megapixel detector array to conduct its survey.
The players
Applied Aerospace
This company was responsible for the initial construction of the sunshade structure at their facility in Stockton, California.
SolAero Technologies
This organization managed the installation of the solar cells onto the sunshade assembly.
BAE Systems
This defense and aerospace contractor is overseeing the current assembly and integration work at their facility in Boulder, Colorado.
The details
The sunshade works by blocking sunlight from entering the 20-inch telescope aperture, a configuration essential for the instrument's infrared sensitivity. To estimate object size, the team will image the same area of the sky over two separate infrared bands.
Timeline
Solar cells were installed on the sunshade in January 2026.
Environmental testing of the structure was completed in March 2026.
The sunshade was delivered to BAE Systems in May 2026.
The Big Picture
This integration milestone marks a crucial step in the development of the NEO Surveyor mission. It advances the design phase for space-based infrared telescopes, effectively replacing older ground-based tracking methods for identifying near-Earth objects.
The success of this hardware integration ensures the spacecraft can maintain the cold temperatures needed for long-term infrared sensing. This capability directly improves our ability to catalog potentially hazardous objects in space.
The takeaway
The successful integration of the power system marks a major logistical milestone for the spacecraft's assembly. Reliable solar power remains a fundamental requirement for the extended operation of orbital observatories.
