NASA announced today that its yearly “Day of Remembrance” for fallen astronauts will be held on February 1. The date marks the 10th anniversary of the day the space shuttle Columbia disintegrated during re-entry into the Earth’s atmosphere. Flags at NASA facilities will be flown at half-staff on that day.

The tribute will be used to honor the astronauts who died while working with the space program. Astronauts from the space shuttles Challenger and Columbia, as well Apollo 1 will be a part of the remembrance. An observance will take place at Arlington National Cemetary on February 1, with NASA Administrator Charles Bolden and other senior NASA officials in attendance.

A wreath-laying ceremony will also take place that day at 10 am EST at the Space Mirror Memorial in the Kennedy Space Center Visitor Complex. The Space Mirror Memorial was dedicated in 1991, to honor astronauts who lost their lives in the space program. It has been declared a National Memorial by the U.S. congress and is maintained by the non-profit Astronauts memorial Foundation, which is also hosting the observance on Friday.

The Kennedy ceremony will be streaming live on NASA Television. A tribute video for fallen astronauts prepared by NASA can be seen below, and an interactive slideshow is also available.
