JOAN CARTAN-HANSEN, HOST:

3
00:00:06,433 --> 00:00:07,800
NO SPACE CRAFT HAS EVER

4
00:00:07,800 --> 00:00:09,066
LANDED ON THE SUN.

5
00:00:09,066 --> 00:00:10,900
IT'S JUST TOO HOT!

6
00:00:10,900 --> 00:00:12,600
BUT THE PARKER SOLAR PROBE WILL

7
00:00:12,600 --> 00:00:14,266
GET PRETTY CLOSE, REACHING THE

8
00:00:14,266 --> 00:00:16,967
SUN'S OUTER EDGE, THE CORONA.

9
00:00:16,967 --> 00:00:18,166
THAT'S WITHIN ABOUT THREE POINT

10
00:00:18,166 --> 00:00:19,633
EIGHT MILLION MILES FROM THE

11
00:00:19,633 --> 00:00:21,000
SUN'S SURFACE.

12
00:00:21,000 --> 00:00:22,533
WHILE THE CORONA CAN BE AS HOT

13
00:00:22,533 --> 00:00:24,600
AS A MILLION DEGREES FAHRENHEIT,

14
00:00:24,600 --> 00:00:26,367
SOME PARTS ARE COOLER.

15
00:00:26,367 --> 00:00:27,600
SO, THE PROBE WILL ONLY HAVE TO

16
00:00:27,600 --> 00:00:29,000
SURVIVE TEMPERATURES OF ABOUT 25

17
00:00:29,000 --> 00:00:31,066
HUNDRED DEGREES FAHRENHEIT.

18
00:00:31,066 --> 00:00:33,000
STILL, THAT'S FOUR TIMES AS HOT

19
00:00:33,000 --> 00:00:35,533
AS THE MELTING POINT OF LEAD.

20
00:00:35,533 --> 00:00:37,600
AT ITS CLOSEST APPROACH, THE

21
00:00:37,600 --> 00:00:40,000
PROBE WILL TRAVEL 430,000 MILES

22
00:00:40,000 --> 00:00:42,700
PER HOUR AROUND THE SUN.

23
00:00:42,700 --> 00:00:44,000
IF YOU COULD TRAVEL THAT FAST ON

24
00:00:44,000 --> 00:00:45,500
EARTH, YOU COULD GO FROM

25
00:00:45,500 --> 00:00:47,533
PHILADELPHIA TO WASHINGTON DC IN

26
00:00:47,533 --> 00:00:49,433
ONE SECOND.
