WEBVTT FILE 1 00:00:02.102 --> 00:00:04.220 One year ago, on September 26, 2 00:00:04.220 --> 00:00:07.223 2022. NASA's DART mission navigated 3 00:00:07.223 --> 00:00:11.194 to the small asteroid Dimorphos and deliberately crashed into it. 4 00:00:11.277 --> 00:00:14.814 Dimorphos is a tiny moon orbiting the asteroid Didymos, 5 00:00:14.814 --> 00:00:19.386 which is just a bit larger than Bennu and composed of stony material. 6 00:00:19.469 --> 00:00:24.324 The DART impact shortened Dimorphos’ orbital period by 33 minutes, making it 7 00:00:24.324 --> 00:00:29.312 the first full scale demonstration of asteroid deflection technology. 8 00:00:29.396 --> 00:00:32.098 This summer, while the Bennu samples were approaching, 9 00:00:32.098 --> 00:00:35.101 Earth, technicians in Titusville, Florida, were preparing 10 00:00:35.101 --> 00:00:39.239 the psyche spacecraft to visit an asteroid of a different type. 11 00:00:39.322 --> 00:00:43.860 Psyche is named after its massive target 16 psyche. 12 00:00:43.860 --> 00:00:49.115 which is about 400 times larger than Bennu and more than three times as dense. 13 00:00:49.199 --> 00:00:52.402 The psyche spacecraft will visit an asteroid that may consist 14 00:00:52.402 --> 00:00:56.790 of a significant amount of nickel ion metal mixed with rock. 15 00:00:56.873 --> 00:01:00.560 It will remotely study 16 psyche's elemental composition, 16 00:01:00.560 --> 00:01:04.030 topography and gravitational and magnetic fields. 17 00:01:04.097 --> 00:01:07.951 The mission will provide insights into the formation of terrestrial planets 18 00:01:07.951 --> 00:01:09.052 like Earth. 19 00:01:09.052 --> 00:01:12.055 Psyche's Launch window opens on October 5th. 20 00:01:12.272 --> 00:01:12.989 November. 21 00:01:12.989 --> 00:01:15.892 Maybe sweater weather for folks in the Northern hemisphere. 22 00:01:15.892 --> 00:01:19.596 But for the Lucy mission, things will just be heating up. 23 00:01:19.679 --> 00:01:23.133 On November 1st, Lucy will train its cameras on the main belt. 24 00:01:23.133 --> 00:01:24.751 Asteroid Dinkinesh. 25 00:01:24.751 --> 00:01:28.555 It will take pictures while rapidly flying by and test its ability 26 00:01:28.555 --> 00:01:31.558 to track asteroids during high speed encounters. 27 00:01:31.741 --> 00:01:35.095 The Dinkinesh flyby will prepare Lucy for its next encounter 28 00:01:35.095 --> 00:01:39.065 with the main belt asteroid Donald Johanson in 2025. 29 00:01:39.149 --> 00:01:43.887 In 2027, Lucy will begin its long trip through the Jupiter Trojans 30 00:01:43.970 --> 00:01:47.540 to swarms of primitive asteroids trapped in Jupiter's orbit 31 00:01:47.540 --> 00:01:51.027 that are thought to be the fossils of planet formation. 32 00:01:51.111 --> 00:01:52.946 As the weather starts to cool down. 33 00:01:52.946 --> 00:01:54.230 Hold on to your hats. 34 00:01:54.230 --> 00:01:56.583 It's going to be an asteroid autumn to remember.
