Thirty years ago today, Space Shuttle Challenger exploded 73 seconds into its journey. Today we hold a special remembrance for the astronauts lost on that mission, as well as those of Columbia and Apollo 1.
I took this image of the left side panel of Challenger on display at the Kennedy Space Center in Florida just a few weeks ago.
Let us remember that space travel is hard, and that we all need to meet the coming frontiers together. That is the only way humanity can push forward, explore the universe, and take the best possible care of the only planet we have.
