KENNEDY SPACE CENTER, FLA. -- Ed White III touches his father's name engraved in the Space Mirror Memorial at the KSC Visitor Complex. White attended the ceremony held in remembrance of the astronauts lost in the Apollo 1 fire: Virgil "Gus" Grissom, Edward H. White II and Roger B. Chaffee. Members of their families, along with KSC Director Bill Parsons, Associate Administrator for Space Operations William Gerstenmaier, President of the Astronauts Memorial Foundation Stephen Feldman and Chairman of the Board of Directors of the Astronauts Memorial Foundation William Potter, attended the ceremony. The mirror was designated as a national memorial by Congress and President George Bush in 1991 to honor fallen astronauts. Their names are emblazoned on the monument’s 42-½-foot-high by 50-foot-wide black granite surface as if to be projected into the heavens. Photo credit:NASA/Kim Shiflett

The NASA SR-71A successfully completed its first cold flow flight as part of the NASA/Rocketdyne/Lockheed Martin Linear Aerospike SR-71 Experiment (LASRE) at NASA's Dryden Flight Research Center, Edwards, California on March 4, 1998. During a cold flow flight, gaseous helium and liquid nitrogen are cycled through the linear aerospike engine to check the engine's plumbing system for leaks and to check the engine operating characterisitics. Cold-flow tests must be accomplished successfully before firing the rocket engine experiment in flight. The SR-71 took off at 10:16 a.m. PST. The aircraft flew for one hour and fifty-seven minutes, reaching a maximum speed of Mach 1.58 before landing at Edwards at 12:13 p.m. PST. "I think all in all we had a good mission today," Dryden LASRE Project Manager Dave Lux said. Flight crew member Bob Meyer agreed, saying the crew "thought it was a really good flight." Dryden Research Pilot Ed Schneider piloted the SR-71 during the mission. Lockheed Martin LASRE Project Manager Carl Meade added, "We are extremely pleased with today's results. This will help pave the way for the first in-flight engine data-collection flight of the LASRE."

The Space Shuttle Endeavour, accompanied by a convoy of recovery vehicles, is towed up the taxiway at NASA's Dryden Flight Research Center at Edwards Air Force Base, California, following its landing on June 19, 2002. The landing, the 49th to occur at Edwards, concluded mission STS-111 to the International Space Station. It was the 18th orbital mission of Endeavour and the 110th space shuttle mission overall.

Retired NASA Dryden research pilot Ed Schneider served as master of ceremonies at the retirement ceremony for NASA's B-52B, on Dec. 17, 2004.
