Corning (GLW) announces participation in NASA’s New Horizons mission

Corning announced that a high-precision opto-mechanical assembly manufactured in Corning’s Keene facility is part of the imaging system of NASA’s New Horizons mission that made its historic pass by Pluto on Tuesday.

Corning provided diamond-turned mirrors and housing that are an integral part of the unmanned spacecraft’s Ralph infrared imager, a remote sensing instrument manufactured by Ball Aerospace to map surface composition and temperature. The Ralph imager has returned the closest-ever colour images of Pluto.

The New Horizons mission, the first spacecraft to the Pluto System and the Kuiper Belt, launched in 2006 and has travelled for nine years to reach the milestone close approach to Pluto. The spacecraft travelled within approximately 7,750 miles of Pluto on July 14. The mission resulted from collaboration among NASA, the Southwest Research Institute, and industry partners. Corning’s high-precision mirrors and housing were engineered as part of the Ralph imager to deliver optical performance that is minimally sensitive to temperature and minimizes thermal gradients.

The diamond-turned mirrors enable the Ralph imager to respond passively to temperature gradients, ensuring it remains in focus. The lightweight mirrors help enable the Ralph imager to run with low power. Corning and Ball Aerospace worked closely to perform the assembly and detailed testing of the Ralph optical engine prior to the mission launch.

“We’ve delivered diamond-turned mirrors and optical components for several NASA missions but are especially proud as the New Horizons mission marked this important milestone,” said Curt Weinstein, vice president and general manager, Advanced Optics, Corning Specialty Materials. “Corning has a long history in space innovation, dating back more than 50 years. With our focus on innovation, we look forward to continued industry collaboration on projects like New Horizons.”

Highlights of Corning’s role in space exploration include making window glass for all of NASA’s manned space missions and the International Space Station, and production of mirrors for the Hubble, Gemini, and Subaru telescopes.
