1 00:00:00,400 --> 00:00:07,040 Planetary defense is finding asteroids before\h they find us but then also maybe getting asteroids\h\h 2 00:00:07,040 --> 00:00:13,520 before they get us. My name is Kelly Fast and I'm\h a planetary defender. In the Planetary Defense\h\h 3 00:00:13,520 --> 00:00:18,560 Coordination Office, I manage the Near-Earth\h Object Observations Program. I handle the program\h\h 4 00:00:18,560 --> 00:00:25,920 that addresses finding the asteroids and this\h handles getting the asteroids. This is the DART\h\h 5 00:00:25,920 --> 00:00:32,080 spacecraft. The DART mission is just a spacecraft\h that is going to go and smack an asteroid. It is\h\h 6 00:00:32,080 --> 00:00:37,680 fantastic to see it in real life. DART will only\h be changing the period of the orbit of Dimorphos\h\h 7 00:00:37,680 --> 00:00:44,240 by a tiny amount and really that's all that's\h needed in the event that an asteroid is discovered\h\h 8 00:00:44,240 --> 00:00:50,640 well ahead of time before it might impact Earth.\h You can't have a mission like DART without finding\h\h 9 00:00:50,640 --> 00:00:55,920 the asteroids first. That involves searching for\h near-Earth asteroids, getting them in the catalog,\h\h 10 00:00:55,920 --> 00:01:00,000 calculating their orbits, tracking them,\h keeping an eye on them. You know as a kid\h\h 11 00:01:00,000 --> 00:01:06,560 I loved astronomy. I love Star Trek. So I became\h a research astronomer my first observing run ever\h\h 12 00:01:06,560 --> 00:01:12,720 was observing the impact of comet Shoemaker-Levy\h9 with Jupiter. I never would have known that\h\h 13 00:01:12,720 --> 00:01:17,840 somehow my career would kind of come full circle\h to be part of something that affects people's\h\h 14 00:01:17,840 --> 00:01:23,120 everyday lives. I feel really honored and humbled\h to be working in the field of planetary defense\h\h 15 00:01:23,120 --> 00:01:27,520 because it can affect people. It's just\h really exciting to have that kind of role\h\h
