Houston, we have a podcast. Welcome to the official podcast of the NASA Johnson Space Center,

episode 7, Total Eclipse Over America. I'm Gary Jordan and I'll be your host today.

So this is the podcast where we bring in the experts, NASA scientists, engineers,

astronauts, all to tell you the coolest stuff about NASA. So today we're talking

about eclipses with Mark Matney. He's a space debris scientist here at the NASA Johnson Space

Center in Houston Texas and he also has degrees in astronomy and space physics and

is an avid eclipse aficionado. We had a great discussion about what an eclipse is, some of the

history of eclipses, and some of the science that we've learned and continue to

learn from them. It was an exciting conversation, especially because on August 21st, 2017, a total solar eclipse

will sweep across America. Mark and I talked about where the eclipse will pass through and

how you'll be able to see it. They don't happen very often. The last time a total

solar eclipse happened over the States was back in 1991 and we won't see another until

2024. Anyway, we'll get into all that good stuff during this episode.

So, with no further delay, let's go light speed and jump right ahead to our talk with Dr. Mark

Mattingy. Enjoy. T-Minais-T-Nis-T minus-I second,

then county. Mark.

There's a long, here she goes. Mark. All right, well, Mark, thank you for coming on the podcast today. Perfect timing because very

soon we're going to have a total solar eclipse that's going to pass over the United States.

And so I think this is a good chance for us to sit down and talk about eclipses and you

went above and beyond for this one, Mark, because you have a lot of different things I mean we're

talking a lot of science we're talking a long and detailed history of eclipses you

know this is not just a oh look at that pretty eclipse now NASA is going
