WEBVTT 2768a25a-8bc5-4b6e-ad77-6579c54c27ed-0 00:00:10.120 --> 00:00:12.240 Greetings, my name is Mason Quick. e060481b-9026-45b3-9e36-8096a30e0fa2-0 00:00:12.960 --> 00:00:16.608 I'm a research scientist in the Earth Science Branch at the e060481b-9026-45b3-9e36-8096a30e0fa2-1 00:00:16.608 --> 00:00:20.316 Marshall Space Flight Center and I'm an expert in the remote e060481b-9026-45b3-9e36-8096a30e0fa2-2 00:00:20.316 --> 00:00:23.964 detection of lightning and thunderstorms using ground based e060481b-9026-45b3-9e36-8096a30e0fa2-3 00:00:23.964 --> 00:00:26.640 airborne and space born instrument systems. 3e72d790-969d-40db-a54e-9fcab62dc2bf-0 00:00:29.200 --> 00:00:33.231 Now our objective is to push forward the technology that's 3e72d790-969d-40db-a54e-9fcab62dc2bf-1 00:00:33.231 --> 00:00:35.760 used to detect lightning from space. 00f218a3-eeca-4c49-867b-8b3b4b13803d-0 00:00:36.400 --> 00:00:39.833 Specifically, we're talking about optical imaging detectors 00f218a3-eeca-4c49-867b-8b3b4b13803d-1 00:00:39.833 --> 00:00:43.266 that detect the pulse of light produced by lightning that's 00f218a3-eeca-4c49-867b-8b3b4b13803d-2 00:00:43.266 --> 00:00:45.040 radiated through the cloud top. 8a404e23-7933-4ec9-8bed-cc9324976557-0 00:00:45.880 --> 00:00:49.652 Now all previous spaceborne missions have used instruments 8a404e23-7933-4ec9-8bed-cc9324976557-1 00:00:49.652 --> 00:00:53.296 that operate in a fixed mode that limits their detection 8a404e23-7933-4ec9-8bed-cc9324976557-2 00:00:53.296 --> 00:00:54.000 efficiency. 54c21cdc-537c-4ac8-b704-1b3b7ec2a1d3-0 00:00:54.960 --> 00:00:59.072 We'd like to implement onboard autonomous event detection and 54c21cdc-537c-4ac8-b704-1b3b7ec2a1d3-1 00:00:59.072 --> 00:01:03.451 sensor optimization so that when a sensor is observing an area of 54c21cdc-537c-4ac8-b704-1b3b7ec2a1d3-2 00:01:03.451 --> 00:01:07.630 interest, specifically an active thunderstorm, it can optimize 54c21cdc-537c-4ac8-b704-1b3b7ec2a1d3-3 00:01:07.630 --> 00:01:11.080 its measurement cadence to improve the measurement. 5784d491-76b6-42de-b7b5-b90f416a280a-0 00:01:13.320 --> 00:01:17.088 And we're also trying to make these lightning instrument 5784d491-76b6-42de-b7b5-b90f416a280a-1 00:01:17.088 --> 00:01:21.121 systems more compact so we can fit them on to small cube sat 5784d491-76b6-42de-b7b5-b90f416a280a-2 00:01:21.121 --> 00:01:22.840 sized satellite platforms. c3aa66b9-1445-470f-9459-2a24dc3251fd-0 00:01:23.560 --> 00:01:27.110 Now, one of the challenges of going up on a small platform is c3aa66b9-1445-470f-9459-2a24dc3251fd-1 00:01:27.110 --> 00:01:30.604 you don't have all the space you'd like to bring up a really c3aa66b9-1445-470f-9459-2a24dc3251fd-2 00:01:30.604 --> 00:01:33.983 powerful computer that can implement your machine learning c3aa66b9-1445-470f-9459-2a24dc3251fd-3 00:01:33.983 --> 00:01:36.160 algorithm or artificial intelligence. a0d2e3cb-abd8-4272-99fc-d35e30f73c25-0 00:01:36.560 --> 00:01:39.979 So we need to develop the capability to implement a0d2e3cb-abd8-4272-99fc-d35e30f73c25-1 00:01:39.979 --> 00:01:44.083 artificial intelligence in a specific way that can be added a0d2e3cb-abd8-4272-99fc-d35e30f73c25-2 00:01:44.083 --> 00:01:47.640 as a modular component to the existing data system. 45a8dcb0-77a8-47ad-8651-12082246b417-0 00:01:50.160 --> 00:01:53.977 A successful implementation would look like a modular unit 45a8dcb0-77a8-47ad-8651-12082246b417-1 00:01:53.977 --> 00:01:57.989 that's capable of ingesting data from the lightning detector, 45a8dcb0-77a8-47ad-8651-12082246b417-2 00:01:57.989 --> 00:02:02.130 identifying an active storm in the field of view, and reporting 45a8dcb0-77a8-47ad-8651-12082246b417-3 00:02:02.130 --> 00:02:06.207 back to the sensor information it can act upon to optimize its 45a8dcb0-77a8-47ad-8651-12082246b417-4 00:02:06.207 --> 00:02:09.960 measurement cadence while it's still observing the storm. f32b3b56-b350-4d11-8cf4-7b2b906c98ee-0 00:02:10.880 --> 00:02:11.000 Now. d474b168-522d-4129-93fc-7f581c06828a-0 00:02:11.000 --> 00:02:14.809 This type of unit could be infused directly into future d474b168-522d-4129-93fc-7f581c06828a-1 00:02:14.809 --> 00:02:18.959 missions to detect lightning from low Earth orbit or even in d474b168-522d-4129-93fc-7f581c06828a-2 00:02:18.959 --> 00:02:20.319 geostationary orbit. f7ddcfc6-4d20-42c5-9c3d-05182250a145-0 00:02:22.000 --> 00:02:24.675 Now lightning is just one type of transient phenomenon that f7ddcfc6-4d20-42c5-9c3d-05182250a145-1 00:02:24.675 --> 00:02:25.880 occurs in the Earth system. 5fdce9ca-4c25-4d6b-b750-132b3cdf9505-0 00:02:26.400 --> 00:02:31.020 Things like volcano eruptions, heavy precipitation events and 5fdce9ca-4c25-4d6b-b750-132b3cdf9505-1 00:02:31.020 --> 00:02:34.896 flooding forest fires are example of fast transient 5fdce9ca-4c25-4d6b-b750-132b3cdf9505-2 00:02:34.896 --> 00:02:38.845 phenomenon that would benefit greatly from optimized 5fdce9ca-4c25-4d6b-b750-132b3cdf9505-3 00:02:38.845 --> 00:02:40.560 measurements like this. 180fa05f-7fb0-40a5-ac95-b32bde51d2fc-0 00:02:44.120 --> 00:02:47.057 Interest in transient phenomenon goes well beyond the Earth 180fa05f-7fb0-40a5-ac95-b32bde51d2fc-1 00:02:47.057 --> 00:02:47.400 system. df97f395-d711-4233-86c8-9540ae87714e-0 00:02:47.920 --> 00:02:51.812 We can talk about flares or prominences on the solar df97f395-d711-4233-86c8-9540ae87714e-1 00:02:51.812 --> 00:02:55.999 surface, geyser or volcano eruptions on planetary moons, df97f395-d711-4233-86c8-9540ae87714e-2 00:02:55.999 --> 00:03:00.627 storms or Aurora events on other planets, Supernova As we move df97f395-d711-4233-86c8-9540ae87714e-3 00:03:00.627 --> 00:03:04.814 into a future paradigm with intelligent sensor networks, df97f395-d711-4233-86c8-9540ae87714e-4 00:03:04.814 --> 00:03:09.074 it's easy to imagine a scenario where identification of a df97f395-d711-4233-86c8-9540ae87714e-5 00:03:09.074 --> 00:03:13.922 specific transient process could enhance the information obtained df97f395-d711-4233-86c8-9540ae87714e-6 00:03:13.922 --> 00:03:16.640 by available sensors in the network.
