Safety is a key NASA core value. NASA’s constant attention to safety is the cornerstone upon which we build mission success.
Every year, NASA holds a Day of Remembrance to commemorate those we have lost, reflect on why we explore, and commit to our safety practices.
In 2024, NASA Day of Remembrance falls on Thursday, Jan. 25. NASA Remembers the crews of Apollo 1, space shuttles Challenger and Columbia, and all members of the NASA family who lost their lives while furthering the cause of exploration and discovery.
