This reel depicts key events during entry, descent, and landing that will occur when NASA’s Perseverance rover lands on Mars February 18, 2021.

Looking for something to do while waiting out COVID-19 at home? You can listen - in real time - as three NASA astronauts experienced REAL isolation, and relied on radio to get them through their disaster. This website replays the Apollo 13 mission as it happened, 50 years ago. It consists entirely of historical material, all timed to Ground Elapsed Time--the master mission clock. Footage of Mission Control, film shot by the astronauts, and television broadcasts transmitted from space have been painstakingly placed to the very moments they were shot during the mission, as has every photograph taken, and every word spoken.

Were you around 50 years ago for the historic landing of Apollo 11 on the moon?

Radio communications played a vital role in the mission.  When seconds count and the station you are talking to is a couple hundred thousand miles away, the importance of the "ABC's" of radio comms become clear - Accuracy, Brevity and Clarity.  The mission used ground-breaking voice and data communications methods that many radio amateurs use today.  (By the way, the radios used on Apollo were supplied by Collins!)
