Hi, my name is Julia Khodabandeh, and I’m a booster subsystem manager

2
00:00:04,680 --> 00:00:07,740
NASA’s Marshall Space Flight Center in Huntsville, Alabama.

3
00:00:08,680 --> 00:00:11,400
This is Rocket Science in 60 Seconds.

4
00:00:13,500 --> 00:00:15,700
The five-segment solid rocket booster

5
00:00:15,780 --> 00:00:19,600
are the largest, most powerful solid propellant booster ever built for flight.

6
00:00:19,820 --> 00:00:24,460
Each of the two boosters will produce more than 3.6 million pounds of thrust,

7
00:00:24,540 --> 00:00:26,900
launching the Artemis missions to the Moon.

8
00:00:29,920 --> 00:00:33,680
Because the SLS rocket is built for deep space missions,

9
00:00:33,740 --> 00:00:36,440
the SLS boosters are designed to be faster

10
00:00:36,520 --> 00:00:38,440
and more powerful than the space shuttle.

11
00:00:38,560 --> 00:00:41,900
The biggest difference is the addition of a fifth propellant segment

12
00:00:42,000 --> 00:00:45,160
so the SLS rocket can send more weight — farther.

13
00:00:46,840 --> 00:00:49,840
The booster motor segments are stacked and mated
