1 00:00:00,510 --> 00:00:04,250 Building the future of quiet supersonic flight … 2 00:00:04,250 --> 00:00:07,260 Science and supplies delivered to the space station … 3 00:00:07,260 --> 00:00:12,450 And uncovering the farthest star ever seen – a few of the stories to tell you about 4 00:00:12,450 --> 00:00:15,059 – This Week at NASA! 5 00:00:15,059 --> 00:00:22,110 We’ve selected Lockheed Martin Aeronautics Company to design, build and test the Low-Boom 6 00:00:22,110 --> 00:00:27,779 Flight Demonstration supersonic experimental aircraft, or X-plane that reduces a sonic 7 00:00:27,779 --> 00:00:28,779 boom … 8 00:00:28,779 --> 00:00:31,940 … to a gentle thump. 9 00:00:31,940 --> 00:00:38,129 Work is expected to last through Dec. 2021 – followed by flights over select U.S. cities, 10 00:00:38,129 --> 00:00:45,760 starting in mid-2022 to collect data about community responses to the flights. 11 00:00:45,760 --> 00:00:51,010 More than 5,800 pounds of scientific experiments and supplies were delivered to the International 12 00:00:51,010 --> 00:00:56,969 Space Station on April 4 to support dozens of the more than 250 investigations aboard 13 00:00:56,969 --> 00:00:58,499 the space station. 14 00:00:58,499 --> 00:01:04,290 The experiments deal with how the human body, plants and materials behave in space. 15 00:01:04,290 --> 00:01:10,320 SpaceX’s Dragon resupply spacecraft delivered the cargo – two days after it was launched 16 00:01:10,320 --> 00:01:11,320 from Florida. 17 00:01:11,320 --> 00:01:17,080 This is the company’s 14th resupply mission to the station. 18 00:01:17,080 --> 00:01:22,740 Our Hubble Space Telescope has uncovered the farthest individual star ever seen. 19 00:01:22,740 --> 00:01:27,840 The enormous blue star – nicknamed Icarus – is located more than halfway across the 20 00:01:27,840 --> 00:01:33,720 universe and would normally be too faint to view, even with the largest telescopes. 21 00:01:33,720 --> 00:01:39,460 But thanks to a quirk of nature called gravitational lensing that tremendously amplifies the star’s 22 00:01:39,460 --> 00:01:43,040 feeble glow, Hubble was able to spot the star. 23 00:01:43,040 --> 00:01:51,000 Icarus is so far away that its light has taken 9 billion years to reach Earth. 24 00:01:51,000 --> 00:01:56,800 Our Chandra X-ray Observatory has been used to study a cosmic cold front located in the 25 00:01:56,800 --> 00:02:03,310 Perseus galaxy cluster that extends for about two million light years, or about 10 billion 26 00:02:03,310 --> 00:02:04,840 billion miles. 27 00:02:04,840 --> 00:02:09,920 The cold front consists of a “cool” band of gas – that is about 30 million degrees, 28 00:02:09,920 --> 00:02:14,269 moving through hot gas that is about 80 million degrees. 29 00:02:14,269 --> 00:02:20,099 It formed about 5 billion years ago and has been traveling at speeds of about 300,000 30 00:02:20,099 --> 00:02:22,580 miles per hour ever since.
