1 00:00:01,050 --> 00:00:04,000 [slate] 2 00:00:04,000 --> 00:00:08,000 [slate] 3 00:00:08,000 --> 00:00:12,000 [slate] Hi. My name is Glenn 4 00:00:12,000 --> 00:00:16,000 Jackson. I’m the NASA LCRD Project Manager. 5 00:00:16,000 --> 00:00:20,000 [slate] 6 00:00:20,000 --> 00:00:24,000 Laser communication is going to be 7 00:00:24,000 --> 00:00:28,000 testing how we can move high bandwidth data 8 00:00:28,000 --> 00:00:32,000 to Earth. Currently we use radio frequency to move data 9 00:00:32,000 --> 00:00:36,000 and video to Earth. Laser communication increases that 10 00:00:36,000 --> 00:00:40,000 bandwidth and allows us to get more data to Earth from astronauts 11 00:00:40,000 --> 00:00:44,000 and science missions. 12 00:00:44,000 --> 00:00:48,000 [slate] 13 00:00:48,000 --> 00:00:52,000 Laser communication is a form of optical communication 14 00:00:52,000 --> 00:00:56,000 Light travels at the same speed 15 00:00:56,000 --> 00:01:00,000 as radio frequency, but it’s a much higher wavelength. 16 00:01:00,000 --> 00:01:04,000 Smaller wavelength. We can increase the amount of data 17 00:01:04,000 --> 00:01:08,000 transmit through optical communication. We’re going to learn how it 18 00:01:08,000 --> 00:01:12,000 transmits through the atmosphere to Earth. We’re going to learn different 19 00:01:12,000 --> 00:01:16,000 operational techniques in weather conditions and wind conditions. 20 00:01:16,000 --> 00:01:20,000 We’re also going to be doing the first bidirectional communication 21 00:01:20,000 --> 00:01:24,000 with a NASA relay called LCRD. 22 00:01:24,000 --> 00:01:28,000 [slate] 23 00:01:28,000 --> 00:01:32,000 [slate] So the public 24 00:01:32,000 --> 00:01:36,000 is not going to be able to see the lasers. They’re in the inferred spectrum 25 00:01:36,000 --> 00:01:40,000 they’re invisible to your eye. But you’ll be able to experience 26 00:01:40,000 --> 00:01:44,000 the benefits of optical communication. Laser 27 00:01:44,000 --> 00:01:48,000 communication operates at a much higher bandwidth, but it also 28 00:01:48,000 --> 00:01:52,000 ... it decreases the amount of weight 29 00:01:52,000 --> 00:01:56,000 and energy needed in spacecraft, space exploration 30 00:01:56,000 --> 00:02:00,000 to communicate. 31 00:02:00,000 --> 00:02:04,000 [slate] 32 00:02:04,000 --> 00:02:08,000 [slate] So yes 33 00:02:08,000 --> 00:02:12,000 NASA communications networking will change with optical communications. 34 00:02:12,000 --> 00:02:16,000 Optical communication increases the bandwidth capability 35 00:02:16,000 --> 00:02:20,000 to gigabytes - ten to a hundred times - more than the radio frequency 36 00:02:20,000 --> 00:02:24,000 capability we have today. This will increase our ability to 37 00:02:24,000 --> 00:02:28,000 network in space and bring the internet around the Moon 38 00:02:28,000 --> 00:02:32,000 and Mars. 39 00:02:32,000 --> 00:02:36,000 [slate] 40 00:02:36,000 --> 00:02:40,000 You can follow along on social media and 41 00:02:40,000 --> 00:02:44,000 on the web at nasa.gov/lasercomms 42 00:02:44,000 --> 00:02:48,000 laser comms is spelled l-a-s-e-r 43 00:02:48,000 --> 00:02:52,000 c-o-m-m-s. Also this Sunday 44 00:02:52,000 --> 00:02:56,000 at 4:00 a.m. join us to watch the launch live. So LCRD 45 00:02:56,000 --> 00:03:00,000 is launching Sunday December 5th. We’ll see you on 46 00:03:00,000 --> 00:03:05,340 NASA TV to watch the launch live. 47 00:03:05,340 --> 00:03:05,344
