NASA Administrator Bill Nelson, from left, NASA Armstrong Flight Research Center Director David McBride, NASA Deputy Administrator Pam Melroy, and NASA Armstrong Deputy Center Director Patrick Stoliker, display the lid to a time capsule on Oct. 13. The time capsule was sealed on the center's 50th anniversary and opened to commemorate its 75th anniversary. NASA Armstrong is in Edwards, California.

NASA Administrator Bill Nelson shows a picture of the X-3 to NASA Armstrong Flight Research Center Director David McBride on Oct. 13. NASA Armstrong Deputy Center Director Patrick Stoliker and NASA Deputy Administrator Pam Melroy also are with Nelson and McBride. The photo was contained in a time capsule that was sealed on the center's 50th anniversary and opened to commemorate its 75th anniversary. NASA Armstrong is in Edwards, California.

Andy Blua and Don Whitfield stand by the time capsule they helped construct 25 years ago on NASA Armstrong Flight Research Center's 50th anniversary. It was recently opened at the center, located in Edwards, California, on Oct. 13, 2021. The time capsule was opened as part of the activities commemorating the center's 75th anniversary.

Neil Armstrong with the Lunar Excursion Module (LEM). Caption: "Not long after this photo was taken in front of the Lunar Landing Research Facility, astronaut Neil Armstrong became the first human to step upon the surface of the Moon." Photograph published in Winds of Change, 75th Anniversary NASA publication, by James Schultz, page 91. Also published in " A Century at Langley" by Joseph Chambers, pg. 95

During a nighttime training session, a multiple exposure captures the movement of the Lunar Excursion Module Simulator (LEMS). The LEMS was a manned vehicle used to familiarize the Apollo astronauts with the handling characteristics of lunar-landing type vehicle. The Apollo Program is best known for the astronaut Neal Armstrong s first step on the Moon July 20, 1969. In its earliest test period, the LEMS featured a helicopter crew cabin atop the lunar landing module. Later, the helicopter crew cabin was replaced with a stand-up rectangular cabin which was more efficient for controlling maneuvers and for better viewing by the pilot. The vehicle was designed at Langley Research Center in Hampton, VA. This multiple exposure shows a simulated Moon landing of the (LEMS) trainer at Langley s Lunar Landing Research Facility. -- Photograph published in Winds of Change, 75th Anniversary NASA publication (page 70), by James Shultz.
