1 00:00:00,208 --> 00:00:07,382 (SFX) 2 00:00:07,382 --> 00:00:10,510 My main interest in planetary science is because it's 3 00:00:10,510 --> 00:00:13,972 the closet part of the cosmos that we can actually go, 4 00:00:13,972 --> 00:00:15,557 see, visit and probe. 5 00:00:15,557 --> 00:00:24,774 ♪ 6 00:00:24,774 --> 00:00:28,069 Psyche is a large asteroid in the main belt that is 7 00:00:28,069 --> 00:00:30,780 in between Mars and Jupiter. 8 00:00:30,780 --> 00:00:34,409 Our experience, so far, in terms of exploring the solar system 9 00:00:34,409 --> 00:00:38,538 has been with either rocky, or icy bodies. 10 00:00:38,538 --> 00:00:40,915 What's particularly interesting about Psyche is 11 00:00:40,915 --> 00:00:42,917 we think it's a metallic object. 12 00:00:42,917 --> 00:00:46,755 We have a common understanding, perhaps, of, you know, how 13 00:00:46,755 --> 00:00:49,382 regular common rocks behave. 14 00:00:49,382 --> 00:00:52,844 But, metal behave in a very different way. 15 00:00:52,844 --> 00:00:55,722 What I contribute to the mission is trying to understand how 16 00:00:55,722 --> 00:01:00,101 cratering and the process of collision and interaction work 17 00:01:00,101 --> 00:01:01,686 for a metallic object. 18 00:01:01,686 --> 00:01:05,356 And, we will use this information, then, to understand 19 00:01:05,356 --> 00:01:08,401 what we see at the surface once we get there. 20 00:01:08,401 --> 00:01:11,988 What we did is take an iron meteorite, 21 00:01:11,988 --> 00:01:14,949 put it in the, in the chamber and use it as a target 22 00:01:14,949 --> 00:01:16,743 for our impetus experiment. 23 00:01:16,743 --> 00:01:19,245 And, we were shooting quartz bit 24 00:01:19,245 --> 00:01:21,956 at high speed in order to produce a crater. 25 00:01:21,956 --> 00:01:25,001 Everything has been filmed with high-speed cameras. 26 00:01:25,001 --> 00:01:27,796 So, we have a tremendous amount of data that shows 27 00:01:27,796 --> 00:01:31,633 in high resolution what happened during the contact, 28 00:01:31,633 --> 00:01:32,884 during the explosion, 29 00:01:32,884 --> 00:01:35,595 and how the crater forms on the surface. 30 00:01:35,595 --> 00:01:39,182 So, everything has been documented in great details. 31 00:01:39,182 --> 00:01:42,268 Here we have a piece of the Gibeon meteorite. 32 00:01:42,268 --> 00:01:46,981 And, what we see here is a crater that was produced in 33 00:01:46,981 --> 00:01:49,651 as a result of one of our experiments. And, 34 00:01:49,651 --> 00:01:53,947 traditionally with rocks, the rim would be blasted away 35 00:01:53,947 --> 00:01:57,283 and would be a sort of a flattish feature. But here, 36 00:01:57,283 --> 00:01:59,786 we see there's flaps that basically, are frozen 37 00:01:59,786 --> 00:02:03,206 into place and this is because the metal is much harder 38 00:02:03,206 --> 00:02:06,209 than rocks. And so, you can then retain 39 00:02:06,209 --> 00:02:08,837 this interesting morphology. 40 00:02:08,837 --> 00:02:12,340 There's going to be a very exciting phase of the mission 41 00:02:12,340 --> 00:02:15,301 when we actually start gathering data. 42 00:02:15,301 --> 00:02:17,387 And, there's going to be lots of surprises. 43 00:02:17,387 --> 00:02:20,723 I just can't wait to be there and see whether or not 44 00:02:20,723 --> 00:02:21,891 there is, you know,
