The near Earth

3
00:00:08.220 --> 00:00:12.380
region is very important, because many satellites are

4
00:00:12.400 --> 00:00:16.400
positioned in this area. They can be very vulnerable to long,

5
00:00:16.420 --> 00:00:20.420
high radiation levels.

6
00:00:20.440 --> 00:00:24.500
So, what we are seeing is what happens when a interplanetary shock

7
00:00:24.520 --> 00:00:28.640
comes and hits the magnetosphere.

8
00:00:28.660 --> 00:00:32.810
Interplanetary shock came from the sun, and it compressed the magnetosphere,

9
00:00:32.830 --> 00:00:37.000
and that compression brought these particles

10
00:00:37.020 --> 00:00:41.060
much inwards. So, these particles are very energetic, and they are

11
00:00:41.080 --> 00:00:45.230
then put in a place where they are not usually seen.

12
00:00:45.250 --> 00:00:49.410
When this happens, the particle intensity

13
00:00:49.430 --> 00:00:53.590
goes up and stays high, which can be very harmful to

14
00:00:53.610 --> 00:00:57.760
satellites in that region, and we need to learn

15
00:00:57.780 --> 00:01:01.940
and understand the processes that create these high levels of radiation

16
00:01:01.960 --> 00:01:06.110
so that we can better design the spacecraft

17
00:01:06.130 --> 00:01:10.280
to avoid any bad effects from the radiation.
