1
00:00:07,430 --> 00:00:05,269
once it's time to come back to earth

2
00:00:10,709 --> 00:00:07,440
orion's service module engines are fired

3
00:00:12,870 --> 00:00:10,719
to leave distant retrograde orbit or dro

4
00:00:14,870 --> 00:00:12,880
the burn sends orion on a five-day path

5
00:00:17,109 --> 00:00:14,880
to come back toward the moon

6
00:00:20,390 --> 00:00:17,119
orion comes very close to the moon again

7
00:00:22,630 --> 00:00:20,400
passing about 60 miles above its surface

8
00:00:24,950 --> 00:00:22,640
then the engines are fired for a second

9
00:00:27,189 --> 00:00:24,960
time and the burn works with the pull of

10
00:00:29,830 --> 00:00:27,199
the moon's gravity to shoot orion back

11
00:00:32,069 --> 00:00:29,840
on a path toward home before entering

12
00:00:33,590 --> 00:00:32,079
earth's atmosphere orion's service

13
00:00:36,310 --> 00:00:33,600
module will separate from the crew

14
00:00:39,110 --> 00:00:36,320
module the crew module will be traveling

15
00:00:41,670 --> 00:00:39,120
at a speed of about 25 000 miles per

16
00:00:44,069 --> 00:00:41,680
hour when it hits the atmosphere orion

17
00:00:46,310 --> 00:00:44,079
will reach temperatures of nearly 5 000

18
00:00:48,630 --> 00:00:46,320
degrees fahrenheit as it slows down due

19
00:00:50,069 --> 00:00:48,640
to air friction that's almost half as

20
00:00:52,549 --> 00:00:50,079
hot as the sun

21
00:00:54,630 --> 00:00:52,559
but don't worry orion has a heat shield

22
00:00:56,389 --> 00:00:54,640
to protect it and parachutes will make
