an exhibition at the Kennedy Space Center Visitor Complex in Florida to respect the astronauts lost when the shuttles Columbia and Challenger exploded, Feb 2003, and Jan 1986

these mementos of the astronauts reminds me of the incredible perfomance by the actors Sarah Cotter and Nathaniel Dunaway of Portal Theatre, in the play 73 Seconds, which is described as:

Time. Space. Disaster. Thirty-one years ago, seven astronauts boarded the Space Shuttle Challenger, and, for 73 seconds, flew into history while the entire world watched.

73 Seconds tells the stories of their lives, the media who covered the event, the children and teachers who watched it live, to the president who had to speak to the families and the nation.

73 Seconds is their story, a brief description of their bravery, wonder, motivation, and courage to set the goal of space flight as their life's achievement.  https://www.portaltheatre.com/about-73-seconds.html  It's stunning.

in 2015 NASA opened this exhibit, with two pieces from the shuttles, that have never before displayed for the public, along with other space memorabilia from the Challenger and Columbia missions.

They’re at the Kennedy Space Center.

The nearly 2,000-square-feet permanent memorial, called “Forever Remembered,” is next to the Space Shuttle Atlantis exhibit. It was designed to honor the two crews lost on missions STS-51L and STS-107, and to pay tribute to shuttle vehicles Challenger and Columbia.

The fuselage piece of Challenger is the first piece of debris available to viewing by the public. The Columbia came apart on re-entry over East Texas, and only 38% has been recovered
