  1. Betsy Congdon Lead Engineer for Parker Solar Probe's heat shield. Curtis Wilkerson - Engineer NASA's Parker Solar Probe is exploring the Sun.
  2. Engineers show us the strength of the spacecraft's protective shield.
  3. Betsy: Here we have a piece of the heat shield for Parker Solar Probe which is a sandwich panel, made of carbon
  4. that is like the graphic epoxy you might find in your golf clubs or your tennis rackets
  5. some carbon foam, and then another piece of carbon-carbon on the back.
  6. It's very light weight, as you can see. And here I've got a blowtorch
  7. and I'm gonna use it to get the front surface of this glowing hot.
  8. And then we will have a nice demonstrator come in and touch the back with his hands.
  9. Let's get this started.
  10. 30 seconds later Betsy: You can start seeing it glowing red. The real heat shield gets up
  11. to about 2500 degrees Fahrenheit which we're not going to do today.
  12. But we are going to get it to a couple of hundred degrees Fahrenheit.
  13. It's glowing pretty good now. Curtis, why don't you touch the back surface of that?
  14. What does it feel like?
  15. Curtis: Pretty cool Betsy: "Nice and cool," he says. Which is just how we like it. Keeping the spacecraft cool.
  16. music tone beeping

Описание от NASA (по-английски)

Betsy Congdon of Johns Hopkins Applied Physics Lab is the Lead Thermal Engineer on the heat shield that NASA's Solar Probe will use to protect itself against the Sun. The shield is so robust, Congdon can use a blowtorch on one side and the other side remains cool enough to touch.
