So…who are your heroes?  People you know personally, people you esteem from afar, people whose lives you admire? I have had the honor of meeting many of my real-life heroes.  One was a fellow astronaut from a different era, Neil Armstrong.  You may remember him, the first human being to set foot on the moon.  His quote that day, July 20, 1969, is famous:  “One small step for a man, one giant leap for mankind.”  He came to the Johnson Space...

Imagine, if someone turned off gravity and everything floated.  How would you keep things in place? Welcome to the world of VELCRO and duct tape.  Was VELCRO a spin-off from the space program? No, but we sure learned how to make good use of it.  Like many great inventions, it came about serendipitously.  In 1941, Swiss electrical engineer George de Mistral went for a walk in the woods and was bothered by the burrs that stuck to his trouser legs...

That is one of the most frequent questions I am asked about my Space Shuttle launches. Would you be scared perched atop four and a half million pounds of explosives with someone about to light the fuse? I had been named as a crew member on a flight that was to launch in June, 1984.  Through many twists and turns in NASA’s schedule, I ended up training for three different flights until an April 12, 1985 launch date was locked in.  We had...

On January 12, 1986, the crew of STS 61C suited up and headed for the Space Shuttle launch pad.  They had been trying get into orbit since December 18…with many grueling attempts that had worn them (and their families) out.  But this day was the right day: no malfunctioning equipment, no boats in the restricted area off the coast, no weather problems in Florida or at the overseas emergency landing sites.  The countdown proceeded, and soon they...

Throwing up is never pleasant.  Imagine what it would be like in weightlessness. Two thirds of space travelers have some form of motion sickness, ranging from dizziness to nausea to vomiting.  It might have been present in the early days of spaceflight, but it became more apparent with the Space Shuttle. From sitting on the launch pad to being weightless took eight and a half minutes.  Unlike astronauts who flew in cramped capsules, Shuttle...

As can be imagined, the NASA managers and engineers were careful about what went on board the Space Shuttle. Each piece of equipment, each item that went into the stowage lockers, each widget or pair of socks had a part number and was catalogued in voluminous detail for each mission. Nothing could be left behind on the ground; nothing could be there that shouldn’t be. All astronauts understood this was a necessary attention to detail for...
