00:00.940 --> 00:03.051
You know , space is hard . It used to

00:03.051 --> 00:04.996
be . All we had to worry about was

00:04.996 --> 00:07.329
astrophysics , kepler's Law , gamma ray ,

00:07.329 --> 00:09.440
solar flares , rocket science , black

00:09.440 --> 00:11.662
holes in the theory of relativity . But

00:11.662 --> 00:13.829
now we also track about 30,000 objects

00:13.829 --> 00:17.520
orbiting it over 17,500 mph . And our

00:17.520 --> 00:19.960
entire way of life depends on us to

00:19.960 --> 00:22.016
protect our satellites from attack ,

00:22.016 --> 00:25.550
day and night . So yeah , space is hard .

00:29.640 --> 00:30.020
Yeah .
