1 00:00:02,700 --> 00:00:06,280 What goes up 2 00:00:06,300 --> 00:00:09,810 must come down. 3 00:00:09,830 --> 00:00:14,840 A NASA-funded balloon experiment has been recovered 4 00:00:14,860 --> 00:00:19,020 a year after flying over Antarctica. 5 00:00:19,040 --> 00:00:25,490 In January 2016, the balloon circled around the continent for 12 days 6 00:00:25,510 --> 00:00:30,400 carrying a telescope designed to study the sun. 7 00:00:30,420 --> 00:00:35,520 The telescope measured high-energy particles generated from solar flares 8 00:00:35,540 --> 00:00:41,070 to better understand how these processes can affect satellites and life on Earth. 9 00:00:41,090 --> 00:00:46,250 After the flight, scientists recovered the data vaults 10 00:00:46,270 --> 00:00:52,190 but due to incoming winter weather, they left the remaining instruments on the ice. 11 00:00:52,210 --> 00:00:58,440 This January, in the Antarctic summer, scientists returned to the landing site 12 00:00:58,460 --> 00:01:03,480 and successfully recovered the instruments and hardware. 13 00:01:03,500 --> 00:01:08,280 Summer is a good time to recover balloon experiments, 14 00:01:08,300 --> 00:01:12,450 and also to launch them. 15 00:01:12,470 --> 00:01:17,210 The sun doesn’t set for a few months in the Antarctic summer, 16 00:01:17,230 --> 00:01:21,480 which allows instruments to observe the sun continuously. 17 00:01:21,500 --> 00:01:26,290 Winds in the stratosphere blow in a circular path around the pole 18 00:01:26,310 --> 00:01:31,060 allowing missions to return roughly to the place they were launched. 19 00:01:31,080 --> 00:01:34,000 With a successful recovery, 20 00:01:34,020 --> 00:01:39,480 scientists are hoping to re-use the instruments for future flights. 21 00:01:39,500 --> 00:01:46,092
