Ball Aerospace completes final phase of DARPA MOIRE telescope program

ball-telescope
Ball Aerospace & Technologies Corp. has completed thermal vacuum environmental tests on critical components for the Defense Advanced Research Projects Agency Membrane Optic Imager Real-Time Exploitation telescope.

Two sections of the primary mirror composite back structure and the structure deployment hinges successfully underwent environmental tests to simulate the temperature range and vacuum of a space environment.

“Results from the environmental tests are very promising for future application of the technology,” said David Kaufman, vice president & general manager for Ball’s National Defense strategic business unit. “By retiring risk and increasing TRL (technology readiness level) of key components we are one step closer to providing persistent imaging from space that many communities are eager to access.”

Image quality from space is dependent on a stable platform. The composite back structure developed by ATK Space Components provides a lightweight option with the required stability needed for persistent imaging from geostationary orbit. Ball Aerospace designed and built the deployment hinges that would be used to unfold the telescope primary in space. Testing the hinges in a relevant environment helps retire risk and proves the required stability characteristics of the primary.

The DARPA MOIRE program is demonstrating the ability to decrease mass and costs of large imaging systems using lightweight diffractive membrane optics. Since the contract award in 2010, Ball Aerospace has been incrementally maturing the manufacturability required for large collection area telescopes (up to 20 meters). The subassemblies used in the most recent test are needed to hold the membrane optics tight and flat, and provide the necessary image quality of the system. Environmental testing of the components is the final phase of DARPA funding for the MOIRE program.

“As a company with a rich heritage in space optics, this is both an innovative program for Ball Aerospace and a paradigm shift,” added Kaufman. “By using replicated optics techniques to deliver affordability there is no longer a lengthy manufacturing process of glass mirrors, but instead a process similar to a printing press.”
