From the time of our conception we have felt gravity.  It is the pull of the Earth on all of us and everything else.  Because we have defined it this way, we say we are at “1g” as we walk around. But did you know that it is possible to feel more than 1g – or less than 1g – here on Earth or in other strange places? I have experienced a whole range of gs.  Some were fun, others scary. When I began my training to fly aboard the Space Shuttle, I...

Just after the Shuttle launched, a warning alarm sounded.  Sensors on one of a pair of components on a critical system had quit.  Pilot Charlie Bolden reached over to a panel on his right and powered off the failed system.  By mistake, he had turned off the working system.  Within moments, the vehicle began gyrating and pitched violently downward out of control toward the ocean.  They were doomed.  Luckily, Charlie, my husband Hoot Gibson, and...

When I got to NASA in 1978, I had a lot to learn. Being a good flight crew member was one of the most important things I would need to know. Shortly after we got to Houston, we began training to fly in the back seat of the NASA T-38 jets. We knew that if we mastered that kind of flying, we might someday train to fly as a crewmember on the Space Shuttle. How was it going to feel flying with some of the best pilots in the nation? Many of my pilot...

In January of 1978, NASA announced its newest class of Astronauts. There would be thirty-five in the class. It would include women and minorities for the first time. They came from across the nation: big cities and farms, Ivy League schools and state colleges, civilian and military, pilots and scientists, Protestants, Catholics, Jews, atheists…and one Buddhist. There were fifteen designated as Pilots and twenty as Missions Specialists. The...

Among Astronauts, there was friendly competition and joking around. Those of us who didn’t come from the military had to learn what this was all about, so we could understand it—and sometimes join in.   It might have sounded like “harassment” but it was all in fun. Pilots who joined the Astronaut Corps had either been fighter pilots or attack pilots. The job of fighter pilots had been to engage enemy fighter pilots. They protected the troops on...
