WEBVTT FILE 1 00:00:01.820 --> 00:00:07.110 NASA’s new Parker Solar Probe is getting some intense environmental testing. 2 00:00:07.130 --> 00:00:13.400 Extreme tests simulate extreme conditions the satellite experiences during launch and beyond. 3 00:00:13.420 --> 00:00:19.200 Parker Solar Probe was built at the Johns Hopkins Applied Physics Lab 4 00:00:19.220 --> 00:00:25.230 and will explore the Sun’s outer atmosphere. 5 00:00:25.250 --> 00:00:31.170 Recently, lasers were fired at the spacecraft to test its solar panels. 6 00:00:31.190 --> 00:00:37.280 These panels will power the entire spacecraft as it travels to the Sun. 7 00:00:37.300 --> 00:00:43.580 Near the Sun, the heat shield must withstand temperatures up to 2,500 degrees Fahrenheit. 8 00:00:43.600 --> 00:00:49.150 Extreme conditions, indeed! 9 00:00:49.170 --> 00:00:55.852
