President Barack Obama on NASA's Day of Remembrance, NASA
"Ten years ago, seven brave astronauts gave their lives in the name of exploration when America's first flight-ready space shuttle, Columbia, failed to return safely to Earth. Each year, on NASA's Day of Remembrance, we honor the crew of that Columbia flight, as well as those of Challenger and Apollo 1, and all the members of the NASA family who gave their lives in the pursuit of expanding our Nation's horizons in space-a cause worthy of their sacrifice and one we must never forget."

"As we honor the memories of those lost in the Challenger, Columbia and Apollo 1 tragedies, we cannot help but to feel immensely grateful for the sacrifice each one of these individuals made when they chose to commit their lives to exploration and discovery. This sacrifice inspires us to strengthen the impact we make in the lives of students so they, in turn, will have the knowledge and interest to pursue meaningful and exciting STEM careers and become the next generation of inspirational leaders."

"Today, the Coalition for Space Exploration joins NASA in observing a Day of Remembrance as the world pays tribute to the men and women who lost their lives while pursuing the development and exploration of space. This year marks the 10th anniversary of the Columbia space shuttle disaster, which resulted in the untimely deaths of seven brave astronauts. We remember their sacrifice and mourn the devastating loss of these crew members, along with the fallen heroes who were aboard Apollo 1, Challenger, and other NASA endeavors. While we grieve because their lives were taken too soon, we are also inspired by their passion and dedication to this commendable program. Their legacy will continue to touch the lives of generations to come, encouraging the exploration of uncharted territory."
