Fifty years ago today, NASA's Apollo 8 mission launched the first astronauts to the moon in an epic (and risky) flight to Earth's nearest neighbor. The Apollo 8 mission didn't land on the moon, but it paved the way for Apollo 11 and other crewed lunar landings that followed, and makred a milestone for human spaceflight.
NASA astronaut Mike Massimino, who flew twice to fix the Hubble Space Telescope, will discuss the importance of the Apollo 8 mission with Space.com today in a Facebook Live between 12:30 p.m. and 12:45 pm. EST (1730-1745 GMT), and what it means for human spaceflight, history and himself. You can tune in on Facebook hereand watch for the Apollo 8 question at the end! We'll be giving away 3 awesome 2019 Year in Space wall calendars to winners.
