The Loss of the Columbia

On February 1, 2003, the orbiter Columbia broke apart in the skies over Texas, just as it was reentering Earth’s atmosphere. The disaster killed all seven astronauts on board.
The destruction of the Columbia grounded the U.S. shuttle fleet and temporarily paused construction of the International Space Station.
The Columbia disaster came almost exactly 17 years after the loss of Challenger in a launch accident on January 28, 1986.
Apollo 1
The loss of the Challenger came almost exactly 19 years after the crew of Apollo 1—Gus Grissom, Edward White, and Roger Chaffee—were killed when a fire swept through their capsule during a launch simulation on January 27, 1967.
“Houston, we’ve had a problem...”
An explosion on Apollo 13 turned a straightforward lunar mission into one of the most storied rescue operations in the history of space flight.
Is crewed space flight worth the risk?
What are the pros and cons of putting humans into space?

A Nonviolent Protest Against Segregation

On the afternoon of February 1, 1960, four African American university students—Ezell Blair, Jr., Franklin McCain, Joseph McNeil, and David Richmond—purchased some items from Woolworth’s general store in Greensboro, North Carolina, and sat at the “whites only” lunch counter in the store’s dining area. The Greensboro Four, as the men came to be called, remained seated while their orders were refused by the waitstaff. They returned the next day, accompanied by some 20 other Black university students, beginning a widespread sit-in movement.
