1 00:00:00,010 --> 00:00:04,020 music 2 00:00:04,040 --> 00:00:08,200 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. 18 00:01:10,300 --> 00:01:14,290 music 19 00:01:14,310 --> 00:01:18,310 tone 20 00:01:18,330 --> 00:01:22,320 tone 21 00:01:22,340 --> 00:01:26,380 beeping 22 00:01:26,400 --> 00:01:30,775 beeping
