Wings to Space, Part I

My First and Last Shuttle Launches

It was 4 a.m. on April 12, 1981.  Sunday was normally a day we’d typically sleep in, but this one was special. We got up extra early to watch the first-ever launch of a space shuttle. Her name?  Columbia, and she was flying mission STS-1, carrying two test pilots Bob Crippen and John Young, plus a load of flight instruments to test her performance during launch, ascent to space, on orbit, and during descent and landing.

It was exciting and scary, but there was NO way I would have slept through such a momentous occasion. Why? Because I am a child of the Gemini and Apollo age and I grew up watching launches. When Columbia made her maiden trip to orbit, it had been a LONG time since the last U.S.-crewed launch. The last human crew to fly to the Moon, for example was on Apollo 17, on December 7, 1972.  The three lunar missions planned to follow up (Apollo 18, 19, and 20) were cancelled to free up money for the space shuttle program. The last official Apollo mission was Apollo-Soyuz, which flew in 1975, and of course, humans went to space to live and work on Skylab in the 1970s.  By the time those were done, I couldn’t imagine a time when we wouldn’t have space travel through NASA. Yet, we had to wait six years from the last Apollo mission until the shuttles began flying.

So, there I was, bleary-eyed in front of our TV that morning, excited, worried and nervous about the success of this next step in U.S. human spaceflight. In typical NASA style, the announcer explained every step, every part of the spacecraft we were seeing. It looked so strange – a moth-shaped plane with wings, attached to a white-painted main tank and two solid rocket boosters. I was used to seeing Saturn Vs lift off, with little modules on top of their stacks. The shuttle was unlike anything I’d seen from NASA. It reminded me of the space planes from 2001: A Space Odyssey, and that morning, it seemed that futuristic realms were one step closer to reality.

Suddenly, the calm, professional NASA-style countdown was down to its final stages.  “T-minus ten, nine, eight, seven, six, five, four, we’ve gone for main engine start, we have main engine start… and liftoff… liftoff of America’s first space shuttle… and the shuttle has cleared the tower…”

In less than five seconds, the shuttle had left the launch pad and was on her way.  I remember being absolutely stunned at how quickly Columbia leapt away from Earth. By contrast, the old Saturn V rockets used to take forever to get away. So, seeing a nimble shuttle and her rockets fairly soar to the sky was a new experience. It was absolutely beautiful, and a sight I have never forgotten.

A few days ago, the world witnessed the final launch in the space shuttle program.  Those of us who were able to be at the Kennedy Space Center counted down the final launch with the announcer. It felt like being at Times Square on New Year’s Eve (but with less people) and chanting the numbers.

For many folks, the sight invoked a steady stream of memories from 30 years of spectacular launches, triumphant returns, and two unbearable tragedies. Throughout that time, I’ve covered a few launches as a member of the press, watched several missions to Hubble Space Telescope as a graduate student working on an HST instrument team, and like so many others in our country, occasionally took the shuttle program for granted – as if it would always be there. But, as with all technology and technological programs, the space shuttles about to become things of the past. They are only part of the path that will keep humans going to space, and I feel fairly certain that the future for space flight in the U.S. will “take off” again.

In the meantime, the part of Florida that has rumbled to the sound of high-powered launches and the double-booms of landings for 30 years, is saying farewell to a bit of space exploration history. It’s a sad time. For folks in Cocoa, Cocoa Beach, Merritt Island, Titusville, Palm Bay, Orlando, and Melbourne, the loss goes beyond running out to the causeway to watch a launch.  Saying goodbye to the shuttles also means bidding farewell to thousands of high-tech jobs as companies such as United Space Alliance (the company responsible for shuttle maintenance and launch operations) lays off waves of workers.

Right now the region’s unemployment rate is hovering around 10.8 percent, but that will worsen once the last wave of shuttle-related layoffs happens. Shuttle workers are crowding into job fairs and going back to school to learn new tricks for new jobs. Many are leaving for employment elsewhere, leaving behind towns that once depended on the property taxes they paid for schools, roads and other infrastructures. Clothing stores, restaurants, recreation shops, and many other businesses fear the worst. Some have shut their doors. It’s unquestionably a tough time, but this is a tough region.  The people survived the shutdown of Apollo, and hopefully they will get through the lean times following this last shuttle launch.

Still, the shuttle program and its workers leave behind a solid record of accomplishments. When I think back to that first launch, there’s no way I could even have imagined just how much science was enabled by the shuttle missions. It’s been a great ride for the past 30 years, and I hope that the future brings something like it to inspire new generations of space enthusiasts.

Shuttle Facts and History

Shuttles are History, But Not Forgotten

Well, shuttle Atlantis has roared into history. And, I find myself, like all the other folks who have watched her lift off, in the position of looking back at 30 years of shuttle missions.

Is this how historians feel as they sift throughmillions of facts about momentous happenings in history? If so, it’s a weird feeling, because as I read through all the facts and figures about the last 30 years of shuttle launches, it does very much feel like the end of a momentous era in the U.S. Space Program.

I’ve been watching shuttle launches for three decades, and it never occurred to me that they’d ever come to an end. Yet, here we are, getting ready for that final launch of space shuttle Atlantis. And, I’ve been doing a little sifting around, watching old launch videos, reading about the accomplishments of the shuttles and their crews, and finding out some really cool and interesting things about these magnificent flying machines.

Did you know that shuttle Atlantis has flown more than 120 million miles in space – and all those before this final mission? She has orbited Earth more than 4,600 times. By the time she comes home from her final trip, Atlantis will have traveled a distance equivalent to 521 times the distance between the Earth and Moon.

Atlantis is the most lightweight of the space shuttle fleet, at 151,315 pounds. Space shuttle Endeavour was three pounds heavier. Every shuttle that left the launch pad had to haul a similar amount of weight plus a payload, pushing against and overcoming the pull of Earth’s gravity to get to space.

Here’s an oddly touching fact: Atlantis is going to space with a man’s wedding ring lost somewhere in her aft crew compartment. According to a report on NASASpaceflight.com, the ring was lost during the servicing flow for the orbiter’s last flight. The report concludes by saying, “While the owner of the ring may have received an ear-bashing from his wife, the engineer can look forward to proudly announcing he was reunited with the space flown ring by Atlantis when she returns to her Orbiter Processing Facility (OPF)… providing she doesn’t take the opportunity to propose to another vehicle whilst on orbit.”

Humans like to give nicknames to the technological marvels they work on. I used to have a sporty little car that I named Tezcatlipoca because it was sleek and black, just like the Aztec jaguar god for which it was named. Well, things are no different for the space shuttles. The people who readied Atlantis for her missions nicknamed the shuttle “Britney”, earned because of her diva-like tendencies during mission preparations.

All of the shuttles have carried scientific/technological payloads. These ranged from experiments in life sciences, materials science, Earth observing studies, astronomy, and classified Department of Defense projects. Atlantis delivered the Magellan spacecraft to Earth orbit and deployment to Venus. It also carried the Compton Gamma-ray Satellite to space, and brought a seven-member crew to complete servicing mission number 4 to the Hubble Space Telescope.

A total of 355 people have flown to space aboard the U.S. space shuttles. Among them have been the first U.S. woman to fly to space (Sally Ride), the oldest (John Glenn, age 77 at the time of his shuttle flight), and astronauts from Israel, Germany, Saudi Arabia, and several other countries. In addition, shuttle missions also ferried such life forms as plant seedlings, insects, shrimp, jellyfish, and rodents in a variety of life-sciences modules to test the effects of low gravity and other conditions.

Space shuttle Columbia flew the longest mission in November 1996. Her combined time on orbit for mission STS-80 was 17 days and 15 hours. In 135 shuttle flights, only two shuttle missions ended in disaster, resulting in the deaths of 14 astronauts. The first was the breakup of 51L, when space shuttle Challenger was destroyed 73 seconds into its launch on January 28, 1986. The second was the destruction of space shuttle Columbia as she disintegrated during her re-entry to the home port on February 1, 2003.

In 30 years, the shuttles have taken us to low-Earth orbit, delivered payloads that extended our eyes to the planets, stars, galaxies, and to the limits of the observable universe. There aren’t too many projects that human kind has taken on that can boast of such achievements. In the days and weeks to come, we will be seeing many tributes to the shuttle program and the people who made it happen. I’m joining in that chorus of praise: “Hail Columbia, Challenger, Discovery, Endeavor, and Atlantis!” It’s been an amazing 30 years!
