In Memoriam
On Thursday, 26 January 2023, NASA observed a day of remembrance, honoring those who lost their lives in pursuit of humankind’s exploration of space’s eternal vastness. In addition to the brave souls lost in the Columbia disaster, the agency seeks to honor astronauts Gus Grissom, Ed White, and Roger Chaffee, the crew of Apollo I, who perished in a launch-pad fire during a 27 January 1967 training exercise, and the seven spacefarers who perished in 1986’s Space Shuttle Challenger disaster.
