NEO Surveyor Spacecraft Gains Solar Power for Mission

Live Poll

Should the government continue to fund large-scale space telescope missions for planetary defense?

Engineering teams have integrated solar arrays onto the sunshade of the NEO Surveyor spacecraft, which is now undergoing assembly at BAE Systems. This hardware development is a completed phase of the mission's construction.

Why it matters

The sunshade is critical for the telescope's function, as it maintains low operating temperatures necessary for the instrument to detect the infrared signatures of potentially hazardous near-Earth objects.

The sunshade stands 20 feet tall with a base width of 8 feet and panels joined at a 23.5-degree angle. It supports 864 interconnected solar cells that generate 2 kilowatts of power for the spacecraft's 20-inch aperture telescope.

The players

NEO Surveyor

A NASA mission utilizing an infrared space telescope designed to track near-Earth objects.

BAE Systems

A global defense and aerospace company managing the integration of the spacecraft assembly in Boulder.

Applied Aerospace

The aerospace engineering firm responsible for the design and construction of the sunshade structure.

SolAero Technologies

A provider of high-efficiency solar cells for space applications that performed the array installation.

The details

The sunshade functions by physically blocking sunlight from entering the 20-inch telescope aperture, enabling the onboard 16-megapixel infrared detector arrays to capture thermal data. By imaging the same sky area over two distinct infrared bands, the mission is designed to estimate the size of detected objects. The assembly process involved constructing the structural frame in Stockton before integrating the solar components and completing environmental testing.

The Tech Race

This assembly milestone moves the NEO Surveyor mission closer to operational status within the competitive landscape of space-based asteroid detection. It marks a departure from earlier ground-based survey methods by placing infrared observation capabilities directly into orbit.

The telescope development will eventually provide the data required to identify and track space rocks that may pose a hazard to Earth. While the hardware assembly is a technical milestone for engineers, the mission's subsequent data releases will serve the public by improving the accuracy of near-Earth object orbit predictions.

The takeaway

The successful integration of the sunshade is a significant step forward in preparing the telescope for its primary infrared surveillance mission. Watch for the mission team to finalize full spacecraft integration ahead of future environmental qualification tests.
