NASA says L3Harris Technologies will design, assemble and integrate the test telescope for the gravitational-wave mission, led by the European Space Agency.

- NASA describes the Engineering Test Unit as a final step toward producing flight hardware.
- The mission is slated to launch in the mid-2030s, according to NASA.

Why it matters: The telescope is part of NASA’s contribution to a mission designed to detect low-frequency gravitational waves.

What’s next: L3Harris will work on the Engineering Test Unit; NASA’s announcement does not give a completion date.
