NASA released a video today to remember the three crews and other fallen astronauts who lost their lives in the pursuit of space exploration.

The agency's annual "Day of Remembrance" falls this year on the 55th anniversary of the Apollo 1 fire. The Challenger shuttle disaster of January 28, 1986 and the Columbia shuttle accident of February 1, 2003 are included in the week that follows.

Apollo 1 was a terrible tragedy, and NASA remembers the loss of those lives. We don't stop our quest. We don't stop our mission, but we continue to move forward in that mission of scientific discovery.

Ronald Reagan and George W. Bush both spoke about the lost space shuttle crews hours after the flights ended.

NASA remembers the Apollo 1 crew and all who lost their lives while furthering the cause of exploration and discovery on the 55th anniversary.

In remembrance of the fallen crews, the agency is holding ceremonies Thursday at centers across the United States. The ceremonies are closed to the public and media due to the coronaviruses, but NASA is posting footage of most of the commemorations online.

Every year, the Day of Remembrance falls in late January or early February because of three accidents that happened in the same period. NASA investigated each of the incidents and changed safety practices to address the causes.
