00:00:01,600 --> 00:00:05,140
Challenge 2 Here's what we know.

2
00:00:05,140 --> 00:00:11,740
The satellite is spinning out of control because the Guidance Navigation and Control System, or GNC, is inoperable.

3
00:00:11,740 --> 00:00:13,900
We suspect sabotage.

4
00:00:13,960 --> 00:00:15,140
The challenge?

5
00:00:15,140 --> 00:00:20,140
Teams must repair the GNC system as quickly as possible to stop the dangerous spinning.
