Schneider Lens Captures High-Definition Images for NASA In-Flight Space Shuttle Heat Shield Inspections

Share Article

Schneider Xenoplan C-Mount lens is a key element in new monitoring system designed to reduce flight risks.

Schneider Optics, Inc. has announced that during NASA’s successful STS-121 mission, the Discovery Space Shuttle utilized a Schneider Kreuznach Xenoplan f2.8/50mm Compact C-Mount lens on the Shuttle’s new orbital inspection boom, which is equipped with high-definition cameras that enable astronauts to scan the orbiter’s exterior for damage while in orbit.

A key safety system on NASA’s Shuttle Return to Flight Program, the imaging system is mounted at the end of the Shuttle’s 50-foot robotic arm and controlled by the crew, enabling them to view real-time streamed high-resolution images on a laptop inside the Shuttle.

After a successful launch into orbit, there were a number of areas on Discovery’s thermal protection system that were deemed “areas of interest” warranting focused inspection via the high-performance camera system. Utilizing the ultra-high-resolution images made possible through Schneider’s Xenoplan lens, the flight crew was able thoroughly inspect the thermal tiles and the gap filler between tiles, and determine that the thermal protection system was sound for a safe re-entry into the earth’s atmosphere.

According to NASA’s requirements, the high-resolution camera system needed to consist of commercial-off-the-shelf (COTS) products that were rugged enough to perform flawlessly under the rigors of a Space Shuttle mission. “The system required a high-quality, low-distortion corrected lens, optimized from 400nm – 1000nm, able to cover the 22mm image circle of the camera’s high resolution CCD,” explained Schneider Optics Chief Executive Officer Dwight Lindsey. “The lens needed to be compact in size, and able to maintain its optical quality after withstanding the G-forces and vibrations of launch, atmospheric re-entries and landings, as well as in the extreme environment of space. Our Compact C-Mounts are known for their ability to permanently lock in iris and focus settings, and perform in even the harshest industrial applications. We’re immensely proud that our Xenoplan Compact C-Mount lens performed flawlessly as an integral part of NASA’s Shuttle Return to Flight Program.”

Discovering damage while in orbit could be a life-saving event -- affording the Shuttle crew the opportunity to repair the damage before re-entry, or, if repairs are impossible, dock with the International Space Station to await rescue from the launch of an additional Shuttle or a Russian Soyuz capsule.

Prior to being used on the new orbital inspection boom, Schneider Xenoplan lenses were also used by NASA as part of a three-dimensional structured light (DSL 3-D) system designed to quantify experimental damage to a panel of Space Shuttle tiles. In laboratory testing, researchers fired pieces of insulating foam (identical to the foam that broke off during the launch of the Shuttle Columbia) at the test panel through a compressed-air cannon. Using the DSL 3-D optical system, which provided an ultra-high-resolution map of the test panel’s surface, researchers were able to determine the existence of even microscopic damage.
