The age of Chuck Yeager. The former U.S. Air Force pilot, officer and flying ace who broke the sound barrier early in the space race was born on yesterday's date in 1923. Coincidentally, NASA announced yesterday that it would open the next class of astronaut applications from March 2 to 31. Minimum requirements include U.S. citizenship, an advanced STEM degree, and at least 1,000 hours as pilot-in-command of a jet aircraft. Members of the incoming class of astronauts could be candidates who could fly missions to the International Space Station, the moon or even Mars. (Dayton Daily News, NASA — February 13, 2020)
