An Inspirational Tragedy
Twenty five years ago today, much of the nation gathered around their televisions to watch another initiative to rekindle interest in science education – The Space Shuttle Challenger’s mission which would carry the first Teacher in Space.
We all know the basic history of that day. If you were alive at the time, you almost certainly remember where you are. It’s a moment etched in the American collective consciousness like the Assignation of JFK, and the attacks of 9/11.
On January 28, 1986, the nation watched what had almost come to seem routine, yet another shuttle launch. NASA’s public affairs officer Steve Nesbitt read the countdown as always. Challenger cleared the launch tower, and all seemed well – until a ghastly cloud of smoke and debris engulfed the shuttle. Everyone was in shock. Nobody knew what had happened. But everyone knew it was wrong. Steve Nesbit’s calm words seconds after the explosion summed it up in a chilling way “Obviously a major malfunction.” NASA didn’t know what had happened yet either.
The space shuttle Challenger and all seven Astronauts, Commander Francis R. "Dick" Scobee; Pilot Michael J. Smith; Mission Specialists Ronald E. McNair, Ellison S. Onizuka, and Judith A. Resnik; and Payload Specialists Gregory B. Jarvis, and Christa McAuliffe were lost.
It would be five more months before the Rogers Commission named launching in temperatures below what the O-Rings were rated for as the technical culprit, and named systemic mismanagement, “go-fever” as a cultural cause for the disaster. Today, on the anniversary of the loss of Challenger and her crew, many stories will be written about what went wrong. I’d like to instead focus on what was right, and what we can learn from these pioneers.
Teaching from 100 miles up
This mission included the culmination of a program announced in 1984 by President Reagan. The Teacher in Space Program was intended to spur interest among
Over 11,000 teachers answered the call and applied for the program. NASA selected 114 educators who would interview for the opportunity in
On July 19, 1985, Vice President George Bush announced two teachers had been selected for the program. Christa McAuliffe, a high school teacher from
Christa McAuliffe’s mission included two 15 minute lessons which would be broadcast across the nation via PBS. The first lesson plan, “The Ultimate Field Trip” was to examine daily life on board a spacecraft, and how it differed from life on Earth. She would explore the different roles of the various crew members. She would explain what kinds of experiments were being conducted onboard. She would even show how very basic things like preparing food, basic movement, exercise, personal hygiene, and sleep are no longer the simple tasks they are on Earth.
The second lesson plan, “Where We've Been, Where We're Going” would be a review of many of the technological benefits that had already come out of the space program, and an exploration of the theorized advantages of manufacturing in microgravity, followed by conjuncture on what the future of manned space flight could bring.
McAuliffe said of the mission “I think it's going to be very exciting for kids to be able to turn on the TV and see the teacher teaching from space. I'm hoping that this is going to elevate the teaching profession in the eyes of the public, and of those potential teachers out there, and hopefully, one of the maybe secondary objectives of this is students are going to be looking at me and perhaps thinking of going into teaching as professions.”
Learning from the students
Connected to the Teacher in Space Project was the Shuttle Student Involvement Program (SSIP). NASA has selected three student teams to design experiments to be flown on board the shuttle. Christa McAuliffe was tasked with carrying out these experiments.
The first experiment was a study of how titanium alloy reacts in microgravity as it’s super-heated. The experiment was designed by Lloyd C. Bruce of
The second experiment was a study of crystal growth in microgravity. The experiment was designed by Richard S. Cavoli of Marlboro, NY. Richard’s experiment involved Lead Iodide crystals, which are useful in imaging systems for detecting gamma rays and X-rays. The hope was that the research could be used to design and build better spacecraft sensors. His research was sponsored by Dr. Charles Seaise of
The final SSIP experiment first involved studying how chicken embryos develop when exposed to the microgravity and radiation of space compared to a control group developing normally on the Earth. It was designed by John C. Vellinge of
Keep in mind, all these ambitious experiments were designed by students while they were still in high school. Allowing students across
Routine life on the cutting edge
Of course, the historic Teacher in Space Project was only a part of the flight NASA called STS-51L. Challenger’s mission was full of experiments that would push the cutting edge and lay the foundation for future endeavors in space.
Challenger’s primary payload was a satellite which when deployed would provide greater communications and tracking capabilities for the shuttle fleet and the future space station. TRDS-B would supplement the existing TDRS-A and when deployed would give NASA over 80% on-orbit coverage for tracking and communicating with the shuttles. It was to be an essential part of the foundation for
Mission Specialist Ellison Onizuka would use an instrument designed specially for this mission called SPARTAN-203 to observe Halley’s Comet. Challenger’s unique vantage point 100 miles above the Earth would allow her to use SPARTAN to observe the comet closer to the sun than possible with Earth based instruments. Observations on the visible and ultraviolet wavelengths would give scientists new data on how comets react as they come close to the sun.
Payload Specialist Greg Jarvis would run a series of fluid dynamics experiments to test the way satellite propellants react to spacecraft maneuvers. The date collected would help design better spacecraft propulsion systems in the future, and possibly better, more efficient fuels for satellites.
Challenger also carried an experiment to study the separation of biomedical materials such as cells and proteins in microgravity. The Phase Partitioning Experiment (PPE) would theoretically have been able to separate cells with higher resolution than could then be obtained in a laboratory.
Challenger’s legacy today
In the same speech that President Obama warned of our “Sputnik Moment”, he also called on Americans to “teach our kids that it's not just the winner of the Super Bowl who deserves to be celebrated, but the winner of the science fair.”
The importance this can not be overstated. The crew of Challenger clearly believed in math, science, and the exploration of space. But what they didn’t believe was that these were obscure little arcane specialties only accessible to a few elites in the rarified halls of Ivy League universities or major research labs. They believed that science and education were accessible to all Americans, and that it was important for all of us to continue to grow and learn. They also believed that
The rest of the world treats science and math education as an economic investment in the future. They treat teachers as nation builders, and they don’t tolerate bad educators. If we want to honor the memory of the crew of Challenger, and the spirit they lived by, we have to pick up the torch, and move forward to rekindle interest in science, math, and the space program. The Challenger seven dedicated their lives, and ultimately gave their lives to that end.

NASA also has an official day of remembrance page to commemorate the crews of Apollo 1, Challenger 51-L, and
