Remember them this Memorial Day!

It's Memorial Day weekend, and I won't be blogging over it, as I'm going to be enjoying my long weekend! (And I hope you are, too.) But I'd like to leave you with some reflections on our history of Space Exploration in this country. (This was originally posted last year.)

There are wonderful things going on in Space Exploration these days, and we know an unprecedented amount about our planet, solar system, galaxy, and Universe as a result of all the exploration that we've done. In fact, that's most of what I write about here. But another huge part of that exploration has been manned spaceflight, and we've learned a tremendous amount about ourselves and how we both relate to and depend on this world as a result of that.

But there's been a cost, too. Being a NASA astronaut is dangerous, and there have been a number of accidents and crashes that have claimed the lives of NASA astronauts. (Not to mention the losses suffered by other space explorers.) Today, I'd like to remember some of the men and women who perished in these disasters.

This picture below is that of a T-38 Talon aircraft.

This was the world's first supersonic jet trainer. It's been in use by the military for nearly 50 years training pilots; it's also the cheapest supersonic aircraft at only $756,000. There have been a number of fatal accidents involving this aircraft, including the following NASA astronauts and astronaut trainees:

• Theodore Freeman was killed October 31, 1964 when a snow goose hit the canopy of his plane, causing fragments to enter his T-38 engines. He ejected, but he was at too low an altitude for his parachute to deploy properly. Theodore was the first NASA astronaut to die in the space program.
• Charles Basset and Elliot See were killed February 28, 1966 when their T-38 crashed in St. Louis, MO. They were the prime crew for the Gemini 9 mission, dying just four months before they were to fly into space.
• Clifton Williams was killed October 5, 1967 when his aircraft controls in his T-38 stopped responding. He crashed near Tallahassee, FL.

After the death of Clifton Williams, there were no training-related fatalities for nearly 20 years. However, there have been others who have been killed in aircraft accidents, including:

• Stephen Thorne, killed May 24, 1986 as a passenger when a Pitts Special Aircraft crashed in Santa Fe, TX.
• S. David Griggs, who was killed June 17, 1989 when a vintage WWII plane that he was flying crashed. He performed the very first unscheduled space walk as part of a satellite rescue on mission STS 51-D. He was scheduled to go back into space as a pilot of mission STS-33 in August of 1989.
• Sonny Carter was killed April 5, 1991, in a commercial airliner crash while on official NASA business. He flew on the same STS-33 flight that David Griggs was slated to pilot, spending six consecutive days in space.
• Patricia Robertson died on May 22, 2001 in Manvel, TX, as a passenger in an experimental aircraft conducting touch-and-go landings.

There are, of course, three much more famous NASA disasters that claimed the lives of many astronauts, and we should not forget those men and women, either.

On January 27, 1967, the American space program was preparing for the Apollo missions. In a training exercise for the Apollo 1 mission, astronauts Virgil "Gus" Grissom (Gemini 3), Ed White (Gemini 4), and Roger Chaffee (Mercury 4) were locked inside the module on the launch pad when a flash fire broke out inside the spacecraft. Unable to open the locks and escape in time, the three of them were burned alive. The Apollo program's command module underwent a massive redesign after that, and there were no manned missions until Apollo 7 in October of 1968 (ironically, manned by the backup crew to Grissom, White, and Chaffee).

January 28, 1986. Do you remember where you were? I was in second grade. I remember how excited my teacher was (hi, Mrs. Goldring!) that a teacher, Christa McAuliffe, was going into space. And we all got to watch it on TV. It was an exciting moment. And then we started watching it, and I remember noticing the flames seeming to climb up the spacecraft, and I said something about it. (I always was a caller-outer.)

And as she was explaining that everything was normal, the shuttle exploded. We were all horrified. Everyone across the nation was horrified when they found out. We all know about the O-ring problem in the solid rocket boosters, but take some time today to remember the seven astronauts who lost their lives in this disaster. Remember, they didn't die in that explosion, it most likely wasn't until they hit the water beneath them that the impact killed them; another horrible way to die.

We have not forgotten you, Gregory Jarvis, Christa McAuliffe, Ronald McNair, Ellison Onizuka, Judith Resnik, Francis Scobee, and Michael Smith.

And finally, there's the Space Shuttle Columbia disaster, which burned up on re-entry.

A piece of foam insulation (nerf-like material) had broken off and struck the left wing well prior to re-entry. Although extremely light, the material was moving very quickly, and tests have shown that it most likely caused significant damage to the shuttle. The spacecraft began to disintegrate upon re-entry with the atmosphere, and it is unknown what the cause of death of the crew members was; whether they suffocated due to a lack of atmosphere or froze to death in the very high altitudes. At the time of the breakup, the shuttle was at an altitude of 203,000 feet (39 miles or 63 km), and was moving at about Mach 18 (13,000 mph or 20,000 km/hr).

All seven astronauts on board were killed. We remember you today, Michael Anderson, David Brown, Kalpana Chawla, Laurel Clark, Rick Husband, William McCool, and Ilan Ramon.

Space exploration is a wonderful research and development tool for humanity, and in a very literal way, has us reaching for the stars. But remember that in addition to its financial costs, there's a very human cost as well. I'll leave you with the words of the poet John Gillespie Magee, Jr., used by President Reagan to eulogize the Challenger crew:

We will never forget them, nor the last time we saw them, this morning, as they prepared for their journey and waved goodbye and 'slipped the surly bonds of Earth' to 'touch the face of God.'
