Annually in January NASA honors the memories of their NASA family who lost their lives while furthering the cause of exploration and discovery.
This includes the crews of Apollo 1 and space shuttles Challenger and Columbia. In 2022, the Day of Remembrance was observed on Jan. 27.
This year’s NASA Day of Remembrance also marks 55 years since the Apollo 1 tragedy. https://www.nasa.gov/specials/dor2022/
