Utilizing HDTV as Data for Space Flight

In the aftermath of the Space Shuttle Columbia accident February 1, 2003, the Columbia Accident Investigation Board recognized the need for better video data from launch, on-orbit, and landing to assess the status and safety of the Shuttle orbiter fleet. The board called on NASA to improve its imagery assets and update the Agency's methods for analyzing video. — This paper will feature details of several projects implemented prior to the return to flight of the Space Shuttle, including an airborne HDTV imaging system called the WB–57 Ascent Video Experiment, use of true 60-Hz, progressive scan HDTV for ground and airborne HDTV camera systems, and the decision to utilize a wavelet compression system for recording. — Compression test results will be included, along with imagery from the launch of STS–114, and details of how commercial components were utilized to image the Shuttle launch from an aircraft flying at 400 knots at 60,000 ft altitude. The paper will conclude with a review of future plans to expand on the upgrades made prior to return to flight.
