Although we grieve deeply, as do the families of Apollo 1 and Challenger before us, the bold exploration of space must go on. Once the root cause of this tragedy is found and corrected, the legacy of Columbia must carry on for the benefit of our children and yours."
A STATEMENT FROM THE FAMILY OF COLUMBIA ASTRONAUT DAVE BROWN. August 27, 2003:
"Thousands of people, including Shuttle debris searchers, NASA personnel, the public, and the accident investigation board helped to determine what happened to the Space Shuttle Columbia and her crew. Together they produced this well- documented report. We are indebted to all of them. We all benefit from this hindsight.NASA contingency planners conceived of an outline for an investigation board and its general membership, and thus set fact-finding off to a fast start. The space planners also foresaw a need for assigning NASA astronauts to assist each family. We are very grateful for their help.
The crew accepted the risk of space flight, because they believed in their scientific mission. Their scientific work was not in vain. One report estimates the known completion of the Columbia crew's scientific investigations to be 60 to 70 percent.
The little boy who chased butterflies grew up to be a space explorer. We miss him terribly. Hundreds and hundreds of letters of sympathy and support have helped in this time of grief. We thank the writers wholeheartedly.
Now it is time to study and implement the report, and to resume exploration. As David said of a possible catastrophe, 'The program will go on. It must go on.'"
Paul & Dorothy Brown, parents; Douglas R. Brown, brother
Quotes from Political Leaders
"The Columbia is lost. There are no survivors. ... These astronauts knew the dangers and they faced them willingly, knowing they had a high and noble purpose in life. Because of their courage and daring and idealism, we will miss them all the more. ... The cause in which they died will continue. Mankind is led into the darkness beyond our world by the inspiration of discovery and the longing to understand. Our journey into space will go on. ... In the words of the prophet, Isaiah, ‘Lift your eyes and look to the heavens. Who created all these? He who brings out the starry hosts one by one and calls them each by name. Because of his great power and mighty strength not one of them is missing.' The same Creator who named the stars, also knows the names of the seven souls we mourn today. The crew of the shuttle Columbia did not return safely to Earth, yet we can pray that all are safely home." President Bush in address to the nation, 2-1-03.
"They dedicated their lives to pushing scientific challenges for all of us on earth. ... They did it with a happy heart, willingly, with great enthusiasm. ... The loss of this valiant crew is something we will never be able to get over." NASA Administrator Sean O'Keefe. Press conference, 2-1-01.
"Two generations ago, the United States embarked on a course of space exploration," Vice President Dick Cheney said. "Today, despite this tragedy, we remain on that course.... The Columbia is lost, but the dreams that inspired its crew remain with us. Those dreams are carried by the families of the astronauts, who even in grief, have urged that America go on with our space program." Houston Chronicle, 2-7-03, p. 20A.
"These brave people gave their lies to conquer the dangers of space in the name of peace, science and the progress of civilization. We will always remember them." Russian President Vladimir Putin in telegram to President Bush. Houston Chronicle, 2-3-03, p. 9A.
"Few things Congress has done have reaped greater rewards than supporting NASA's mission. But just as important as adequate funding is that NASA defines a clear vision for the future. The tragic loss of the seven astronauts aboard the space shuttle Columbia was a wake-up call to Congress and the American people. We must renew our commitment to space exploration....In the new millennium, NASA must set forth a distinct mission that outlines clear objectives and goals." U.S. Senator Kay Bailey Hutchison, 2-9-03, Houston Chronicle, p. 4C.
"The space program has its roots in Texas, thousands of men and women are employed at the Johnson Space Center. They are the heroes who push the envelope of discovery, innovation. They have contributed greatly to our quality of life and we remain 100 percent behind their mission." Texas Governor Rick Perry. Houston Chronicle, 2-3-03, p. 10A.
"As the most fitting tribute to their courageous service and sacrifice, let us recommit ourselves to the defining dream that dominated their lives - a bold vision for America in space." House Majority Leader Tom DeLay, The Citizen, 2-5-03, p. 11A.
"The space shuttle plays a critical role for our nation's space program. I am determined to work with my colleagues on the House Space and Aeronautics Subcommittee to understand what happened and to ensure a safe human spaceflight program in the future." Congressman Nick Lampson, The Citizen, 2-5-03, p. 11A.
"The space shuttle Columbia and its crew obviously served as a symbol of freedom and cooperation for so many different countries and was dedicated to providing a better life for science and exploration for future generations.... As we all look forward may we never forget their bravery, their sacrifice and their commitment to better all mankind." Texas Lt. Gov. David Dewhurst. Houston Chronicle, 2-4-03, p. 10A.
"Houston is the world's Space City. We, along with all Americans, are grieving deeply today." Mayor Lee Brown, The Citizen, 2-5-03, p. 11A.
"They are our neighbors. They are our friends. We will have time for our private grief only when our duties and responsibilities have ended." Harris County Constable Bill Bailey, The Citizen, 2-5-03, p. 11A.
"Some say we've been too maudlin this past week. Some say we've overdone the attention to the tragedy. There are even some who say we don't need and shouldn't have a space program. Yes, and some used to say the Earth was flat." Houston Chronicle editorial board, 2-9-03, p. 40A.

"The future still holds great possibilities. We have to start thinking seriously about the notion of public space travel and commercial activity in space. Beginning with government research and exploration, we need to move toward private citizens in space. We must develop mature rockets and spacecraft as well as hotels and habitats in low earth orbit for public space travel. From that base we can venture beyond Earth orbit to the moon, to asteroids and to Mars." Buzz Aldrin, Houston Chronicle, 2-4-03, p. 25A.

If you want to be an astronaut, you have to know about the risk. Obviously there's a big risk. You're riding on a rocket. This is an obstacle, but they're going to fix this and that's going to be one less thing to worry about, so if I'm an astronaut, I'll be even safer. Those astronauts died to make the space shuttle better." Alexa Billow, 14 who had an experiment on Columbia. Houston Chronicle, 2-4-03, p. 7A.
Laurel Clark's son Iain returned to class at St Thomas the Apostle Episcopal School on February 10. "At lunch time, I asked Iain if I could give him another hug," teacher Moisina Sanxhaku said.

Houston Chronicle This Week Zone 6, 2-13-03, p. 4.
The Future of Humans in Space
"The fundamental contribution that NASA makes to this country is genuinely spiritual," Oberg said. "What they do is remind us that cultures that explore have a future. NASA's activities are at the heart of that. If they blow it, if they don't play in a credible way, that future is in jeopardy." James Oberg, 2-9-03, Houston Chronicle, p. 21A.
"The fact is, the space shuttle is a virtual Swiss army knife in space," said Brian Chase, Executive Director of the National Space Society... "The problem is that all of that capability makes it inherently expensive to operate." 2-9-03, Houston Chronicle, p. 20A.
"The shuttle should be replaced," said Robert Zubrin, president of the Mars Society. "We should not be flying the shuttles in 2025. It's ludicrous. It's not an invitation to disaster, it will be disaster." 2-9-03, Houston Chronicle, p. 20A.
"Let this be the memorial for the crew of Columbia STS-107, as well as those of Challenger 51L and Apollo 1: a renewed purpose to open up the high frontier of space not just for the few, but for all people. If, within the lifetimes of most people reading this, human civilization will have expanded to the moon, to Mars and beyond, then these heroic hearts will have not given the last full measure of devotion in vain." Mark Whittington, 2-9-03, Houston Chronicle, p. 4C.
"I convinced myself that it might not succeed but that this was my destiny," Tito said. "This was what I was going to do to complete my life. If somehow I didn't make it, I would have had that second life that I had with those eight days in space. That would have been really better, even if my life had ended, than not having done that. In the long run, we're all dead. It's just a matter of what kind of life you have while you're here." Dennis Tito, first space tourist. Houston Chronicle, 2-5-03, p.4D.
"What the Columbia accident did was bring more public attention to bear on a problem that was already there," said Brian Chase, director of the Washington, D.C.-based National Space Society. "I expect the report will stir discussions for the next year or two in political circles about what we do from here." Rather than an Apollo-type sprint to Mars, the space program probably will take a more incremental approach to future exploration initiatives, he added. "I don't see us going for another Apollo-type. I think what we're looking at is a building-blocks approach to get us there," he said. 8-26-03, posted on www.nss.org
Why do spacecraft get so hot passing through the atmosphere? To get into space, a spaceship must go fast enough to fall without hitting the ground. Think of hitting a baseball. The harder you hit it, the faster it goes and the farther it travels before gravity pulls it to the ground. If you had enough energy to make it go 5 miles per second like the space shuttle, it would go past the horizon before being bent toward the ground. It would fall around the Earth in a big circle called an orbit.
To return to Earth, the shuttle must slow down. The shuttle fires its engines into the direction it is going. This slows it down some. The atmosphere provides the rest of the braking. When two things rub together, they get hot. (The rubbing force is called friction.) When the shuttle slaps into the atmosphere, it heats the air so much it turns into red hot gas of about 3,000 degrees F. The shuttle tiles shield the vehicle's aluminum skin from this heat. Aluminum melts at about 1,200 degrees F.
The early investigation focused on the landing gear wheels which are tucked inside the shuttle's wings during launch and while in orbit. (There is a set of tires in each wing and another set in the nose area.) The hollow place where the tires are shielded behind latched doors covered with tiles are called wheel wells. Sensors in and near this area on the left side of the shuttle either showed higher than normal temperatures or quit working. The ones that quit working had their wires melted. The last 2 seconds of recovered data showed that fluid in pipes in the wheel well had all leaked out. The pipes must have melted. Super-heated air must have gotten past the tile shield. Evidence this was true comes from a latch from the left wheel well door that was found in the debris. This latch is made of titanium. One corner was melted which means that the latch was exposed to temperatures of over 3,000 degrees. This latch is on the INSIDE of the wheel well, and should have been protected from the superheated air of that temperature outside.
The shuttle has what are called elevons that are like flaps on a jet that move up and down and keep the shuttle on course. The fluid in the pipes, called hydraulic lines, is what makes these elevons, and other control surfaces on the shuttle, move. Once the fluid vented, the only way to control the shuttle was to use the small jets. Data shows the jets were firing like crazy and still unable to keep the shuttle going nose first and belly down. If the shuttle flipped over or turned sideways, it would immediately shatter.
The Columbia Accident Investigation Board (CAIB) zeroed in on what caused hot gas to get into the wing. A piece of foam from the orange External Tank came off 81 seconds after launch and hit near the leading edge of the left wing. This is the same area that sensor data showed suffered the first signs of heat damage. (As of 3-18-03, micro-meteorite impact during orbit was considered "very unlikely.") Damage to this area was confirmed when a data recorder was recovered in the debris.
Another confirmation that damage happened during launch was that a military camera saw an object separate from the shuttle about 24 hours into the mission. (This information was not known until four days after the accident when the military checked standard sky sweeps for anything that might help the investigation.) Its speed shows that this object came from the shuttle and was not space junk. Radar tests have since determined that it was likely a part of the left wing called a T-seal. These seals join the wing panels together and are held on by 4 bolts. The age of the shuttle may have been a factor in loosening the bolts (from severe shaking during launch) or weakening the wing structure (from exposure to weather and space). The foam impact was then able to crack a wing seal or panel that then floated off in space. The gap left behind allowed hot gas to burn through the wing like a blow torch. An astronomer watching the shuttle entry over California said it looked like it had dropped a flare. These objects were pieces of the wing coming off. A groundtrack of the debris showed that pieces of the left wing fell off first and fell farther west than pieces of the right wing.
The final CAIB report, released August 26, 2003, confirmed that the foam was the physical cause of the accident. The University of Houston Clear Lake library has a copy.

Columbia was the first space shuttle. It launched for the first time on April 12, 1981. The crew was John Young and Robert Crippen. The Columbia mission prior to STS-107 was STS-109, the Hubble repair flight in 2002.
Including STS-107, the space shuttle Columbia flew 28 missions from 1981 to 2003 with 131 individuals on board. 21 people flew on Columbia twice, and 4 flew on it 3 times. The missions (in order flown) were STS 1-5, 9, 61-C, STS-28, 32, 35, 40, 60, 52, 55, 58, 62, 65, 73, 75, 78, 80, 83, 94, 87, 90, 93, 109, 107.

If you have a technical question about Columbia, I'll try my best to answer. I have copies of Columbia technical data, STS-107 press kit, and the final CAIB report.
The expression of support and sympathy from people all over the world gives those of us in the space community hope that the mission of Columbia, to explore the frontiers of space and knowledge, will never be lost.
