“We remember the crews of Apollo 1 and space shuttles Challenger and Columbia with great sadness. I am humbled by their heroism, which truly did help further the cause of exploration and discovery. I am so grateful for the contributions of all of our astronauts and the entire NASA family for all that they do to continue America’s leadership in space. This day also serves as a reminder that space is hard and that safety needs to remain our priority in all our human spaceflight activities.” - Congresswoman Eddie Bernice Johnson
