On May 2, 1952, the world’s first commercial jet airliner, the de Havilland Comet 1, began its maiden airline service from London to Johannesburg.

On March 18, 1965, Alexei Leonov did what no human had ever done before—he stepped out of a spacecraft and into the vacuum of space. Suspended above Earth with only a thin tether holding him to life, Leonov’s daring walk marked a turning point in the early Space Race.

On March 2, 1972, Pioneer 10 lifted off from Cape Canaveral, Florida. It became the first spacecraft to travel beyond the outer planets and eventually the first human-made object to head out of the Solar System.

On February 1, 2003, the space shuttle Columbia broke apart during reentry, killing all seven astronauts on board. The disaster stunned the nation and forced NASA to confront hard truths about risk, decision-making, and the future of human spaceflight.
