Remember when you were young and you asked to borrow your parents’ car for a date?  What if you could borrow something faster? Say… a jet?  When I became an astronaut, non-pilot Mission Specialists (MSs) had to learn to fly in the backseat of NASA’s T-38 jets. We had instruction in the communication and navigation systems followed by training in doing the actual flying. The T-38s were slick little planes. They could speed around at 700...

“It ain’t rocket science” is often a term used to mean something isn’t as difficult as the building of rockets. For me, it meant the science that was done on rockets—like what I did on my Shuttle flights. Not long ago, I gave a talk to a group of research scientists who are performing ground-breaking studies in many engineering and science fields. I read summaries of their work…so complex I couldn’t understand it all. I began to think the...

Before we became Astronauts, NASA wanted to make sure we didn’t have a shady past. The application paperwork was extensive. If we were invited for an interview, we had a background check. When I returned from my week-long job interview at the Johnson Space Center, a neighbor came to see me. “Did you do something wrong?” he asked. “Some guy with an FBI badge came around asking questions about you.  He wanted to know whether you hung out with...

Our universe is vast—but that doesn’t mean things don’t run into each other.  Some say our moon was formed out of the debris from an Earth impact with a huge boulder named Theia. And later in Earth’s history, the dinosaurs and most life on our planet may have been destroyed by collision with an asteroid. On some dark nights, we can see meteors burning up as they enter our atmosphere. It’s no surprise then that our spacecraft sometimes get...

Have you ever had the feeling that you were being watched?  I grew up that way. When you live in a small town where your family has lived for generations, everyone knows your pedigree and knows who you are.  Do something wrong and your momma, grandmamma, and great-grandmamma are sure to find out.  It tends to keep you out of trouble. I was shy and quiet when I entered high school.  Then, I was selected to be a cheerleader, and I was expected to...

When Hurricane Harvey ripped through Houston, it brought back memories of my NASA days in that area.  Thirty-four years ago this month, my husband, fellow Astronaut, Hoot Gibson, and I experienced a fearsome hurricane up close. The Johnson Space Center is located near the Texas Gulf Coast, half-way between Houston and Galveston.  It has seen its share of storms.  Our home for much of our astronaut careers was on a bayou…not far from Galveston...
