00:00:00 --> 00:00:03 Welcome to Astronomy Daily. I'm Anna and
00:00:03 --> 00:00:05 it's time to dive into the fascinating
00:00:05 --> 00:00:07 universe of space exploration and
00:00:07 --> 00:00:10 astronomical discoveries. Today we've
00:00:10 --> 00:00:12 got a packed episode that spans
00:00:12 --> 00:00:14 everything from regulatory victories to
00:00:14 --> 00:00:16 scientific breakthroughs and even a
00:00:16 --> 00:00:17 touch of nostalgia for space
00:00:17 --> 00:00:20 enthusiasts. In our cosmic journey
00:00:20 --> 00:00:22 today, we'll start with some significant
00:00:22 --> 00:00:24 news from SpaceX, which has just
00:00:24 --> 00:00:26 received crucial FAA approval to
00:00:26 --> 00:00:27 dramatically increase its Starship
00:00:28 --> 00:00:29 launch cadence from Texas.
00:00:30 --> 00:00:31 This regulatory green light could
00:00:31 --> 00:00:33 accelerate Elon Musk's ambitious Mars
00:00:33 --> 00:00:36 mission timeline and represents a major
00:00:36 --> 00:00:38 milestone for commercial space flight.
00:00:38 --> 00:00:40 Then we'll travel to India where the
00:00:40 --> 00:00:41 country's space agency has announced
00:00:41 --> 00:00:43 plans for its first human spaceflight
00:00:43 --> 00:00:46 mission scheduled for early
00:00:46 --> 00:00:48 2027. This development marks another
00:00:48 --> 00:00:50 step in India's rapidly expanding space
00:00:50 --> 00:00:53 program and reflects the growing global
00:00:53 --> 00:00:56 democratization of space exploration.
00:00:56 --> 00:00:58 We'll also examine how Stratalaunch has
00:00:58 --> 00:01:00 breathed new life into hypersonic flight
00:01:00 --> 00:01:02 testing, successfully flying and
00:01:02 --> 00:01:04 recovering a vehicle that reached speeds
00:01:04 --> 00:01:07 over Mach 5. This achievement represents
00:01:07 --> 00:01:09 the first time in six decades that
00:01:09 --> 00:01:11 anyone in the United States has flown a
00:01:11 --> 00:01:13 reusable hypersonic rocket plane since
00:01:13 --> 00:01:17 the iconic X-15 program. For astronomy
00:01:17 --> 00:01:18 enthusiasts, we've got exciting news
00:01:18 --> 00:01:20 from the James Webb Space Telescope,
00:01:20 --> 00:01:22 which has captured dramatic weather
00:01:22 --> 00:01:24 changes on a nearby pair of brown
00:01:24 --> 00:01:26 dwarfs. These observations provide
00:01:26 --> 00:01:28 unprecedented insights into these
00:01:28 --> 00:01:30 fascinating objects that bridge the gap
00:01:30 --> 00:01:32 between planets and
00:01:32 --> 00:01:34 stars. And finally, for those who
00:01:34 --> 00:01:36 appreciate the intersection of space
00:01:36 --> 00:01:38 history and creative building, we'll
00:01:38 --> 00:01:40 look at LEGO's newlyannounced shuttle
00:01:40 --> 00:01:42 carrier aircraft set. This detailed
00:01:42 --> 00:01:45 model recreates NASA's modified Boeing
00:01:45 --> 00:01:48 747 jetliner and the prototype orbiter
00:01:48 --> 00:01:50 Enterprise as they appear during their
00:01:50 --> 00:01:54 historic 1983 International Tour. So,
00:01:54 --> 00:01:55 buckle up as we launch into today's
00:01:55 --> 00:01:57 space news roundup. There's plenty to
00:01:57 --> 00:01:59 discover in the coming minutes as we
00:01:59 --> 00:02:01 explore the latest developments in our
00:02:01 --> 00:02:04 ongoing adventure to understand the
00:02:04 --> 00:02:07 cosmos. Kicking things off, SpaceX has
00:02:07 --> 00:02:09 just received a significant regulatory
00:02:09 --> 00:02:11 victory that will substantially boost
00:02:11 --> 00:02:14 its Starship program. On Tuesday, the
00:02:14 --> 00:02:16 Federal Aviation Administration granted
00:02:16 --> 00:02:18 the company approval to increase its
00:02:18 --> 00:02:19 annual Starship rocket launches from
00:02:20 --> 00:02:23 Texas from just five to an impressive 25
00:02:23 --> 00:02:26 launches per year. This represents a
00:02:26 --> 00:02:28 five-fold increase in potential launch
00:02:28 --> 00:02:30 capacity and marks a crucial step
00:02:30 --> 00:02:33 forward for Elon Musk's ambitious space
00:02:33 --> 00:02:36 exploration plans. After completing a
00:02:36 --> 00:02:39 year'slong environmental review, the FAA
00:02:39 --> 00:02:41 determined that this dramatic expansion
00:02:41 --> 00:02:43 in launch frequency would not
00:02:43 --> 00:02:45 significantly impact the quality of the
00:02:45 --> 00:02:47 human environment surrounding SpaceX's
00:02:47 --> 00:02:51 Starbase facility in Bokh Chica, Texas.
00:02:51 --> 00:02:52 The decision applies not only to the
00:02:52 --> 00:02:55 increased rocket launches, but also
00:02:55 --> 00:02:57 covers booster landings in various
00:02:57 --> 00:02:59 bodies of water and potential rocket
00:02:59 --> 00:03:01 explosions over the Gulf of Mexico and
00:03:01 --> 00:03:03 some international waters. This
00:03:04 --> 00:03:05 regulatory green light comes at a
00:03:06 --> 00:03:08 strategically important time for SpaceX,
00:03:08 --> 00:03:10 just days after residents living near
00:03:10 --> 00:03:12 Starbase voted to incorporate the area
00:03:12 --> 00:03:15 as a municipality. This local governance
00:03:15 --> 00:03:17 change gives SpaceX greater control over
00:03:17 --> 00:03:19 the sprawling site's growth and provides
00:03:19 --> 00:03:22 new powers concerning its launch
00:03:22 --> 00:03:24 operations. The incorporation vote
00:03:24 --> 00:03:26 reflects the complex relationship
00:03:26 --> 00:03:29 between SpaceX's rapid expansion and the
00:03:29 --> 00:03:30 local community that has developed
00:03:30 --> 00:03:33 around it. As a condition for increasing
00:03:33 --> 00:03:35 its launch activities, SpaceX must
00:03:35 --> 00:03:37 fulfill various community obligations to
00:03:37 --> 00:03:39 offset environmental impact. These
00:03:39 --> 00:03:41 include hosting quarterly beach
00:03:41 --> 00:03:43 cleanups, donating to environmental
00:03:43 --> 00:03:45 organizations, testing nearby water
00:03:45 --> 00:03:47 quality, and minimizing launch site
00:03:47 --> 00:03:49 lighting to avoid disruption to nesting
00:03:49 --> 00:03:51 sea turtles. The Starship rocket system
00:03:51 --> 00:03:54 with its 171 ft tall spacecraft sitting
00:03:54 --> 00:03:58 a top a 232t tall superheavy booster has
00:03:58 --> 00:04:00 already conducted eight integrated test
00:04:00 --> 00:04:01 flights since
00:04:01 --> 00:04:04 2023. Each launch has demonstrated
00:04:04 --> 00:04:06 progressive achievements, though some
00:04:06 --> 00:04:08 have ended an explosive mishaps that
00:04:08 --> 00:04:10 reflect SpaceX's risky but innovative
00:04:10 --> 00:04:13 test to failure development approach.
00:04:13 --> 00:04:15 Despite Tuesday's positive regulatory
00:04:15 --> 00:04:17 decision, SpaceX has not yet announced
00:04:17 --> 00:04:19 when it plans to conduct its next
00:04:19 --> 00:04:21 Starship test launch. The most recent
00:04:22 --> 00:04:23 two test flights ended with in-flight
00:04:23 --> 00:04:25 explosions, including one that rained
00:04:26 --> 00:04:27 debris over the Turks and Kaikos
00:04:27 --> 00:04:29 Islands, where many residents reported
00:04:29 --> 00:04:32 it felt like an earthquake. This FAA
00:04:32 --> 00:04:34 approval represents a significant boost
00:04:34 --> 00:04:36 for a rocket program that's poised to
00:04:36 --> 00:04:38 play a key role in the future of the US
00:04:38 --> 00:04:40 space program, particularly under the
00:04:40 --> 00:04:43 new presidential administration. With
00:04:43 --> 00:04:45 this regulatory hurdle cleared, SpaceX
00:04:45 --> 00:04:47 can accelerate its development timeline
00:04:47 --> 00:04:50 for a rocket system that's ultimately
00:04:50 --> 00:04:53 designed to carry humans to Mars.
00:04:53 --> 00:04:56 Next in today's news, in a major
00:04:56 --> 00:04:58 development for India's space ambitions,
00:04:58 --> 00:05:00 the country's space agency has announced
00:05:00 --> 00:05:02 plans to launch its first human
00:05:02 --> 00:05:05 spaceflight mission in early 2027. This
00:05:05 --> 00:05:07 announcement marks a significant
00:05:07 --> 00:05:09 milestone in India's growing presence as
00:05:09 --> 00:05:11 a global space power coming after years
00:05:11 --> 00:05:13 of methodical preparation and
00:05:13 --> 00:05:15 technological development. The Indian
00:05:15 --> 00:05:18 Space Research Organization or ISRO
00:05:18 --> 00:05:20 plans to begin with an uncrrewed orbital
00:05:20 --> 00:05:22 mission later this year as a critical
00:05:22 --> 00:05:25 stepping stone toward the human mission.
00:05:25 --> 00:05:26 According to science and technology
00:05:26 --> 00:05:29 minister Jatendra Singh, it represents
00:05:29 --> 00:05:32 India's rise as a global space
00:05:32 --> 00:05:35 power. The mission known as Gagan which
00:05:35 --> 00:05:37 translates to spacecraft is progressing
00:05:37 --> 00:05:39 on schedule with recovery trials already
00:05:39 --> 00:05:41 conducted with the Indian Navy and more
00:05:42 --> 00:05:44 sea recovery simulations planned. Four
00:05:44 --> 00:05:46 Indian Air Force pilots have been
00:05:46 --> 00:05:48 selected as astronaut designates for the
00:05:48 --> 00:05:50 historic mission. These pilots have
00:05:50 --> 00:05:52 already completed specialized training
00:05:52 --> 00:05:55 in Russia and are now undergoing further
00:05:55 --> 00:05:57 mission specific training in India. This
00:05:57 --> 00:05:59 comprehensive preparation underscores
00:05:59 --> 00:06:02 the meticulous approach ISRO is taking
00:06:02 --> 00:06:04 to ensure mission success and astronaut
00:06:04 --> 00:06:07 safety. What makes India's approach
00:06:07 --> 00:06:09 particularly notable is its ability to
00:06:09 --> 00:06:11 achieve significant space milestones at
00:06:12 --> 00:06:13 a fraction of the cost compared to
00:06:14 --> 00:06:16 established space powers. Last August,
00:06:16 --> 00:06:18 India became just the fourth nation
00:06:18 --> 00:06:20 after Russia, the United States, and
00:06:20 --> 00:06:23 China to successfully land an unmanned
00:06:23 --> 00:06:25 craft on the moon with its Chandrean 3
00:06:25 --> 00:06:28 mission. Looking even further ahead,
00:06:28 --> 00:06:30 Prime Minister Narendra Modi has
00:06:30 --> 00:06:32 outlined an ambitious vision for India's
00:06:32 --> 00:06:35 space program, announcing plans to send
00:06:35 --> 00:06:38 an Indian to the moon by 2040. This
00:06:38 --> 00:06:40 long-term goal demonstrates India's
00:06:40 --> 00:06:42 commitment to establishing itself as a
00:06:42 --> 00:06:44 major player in space exploration for
00:06:44 --> 00:06:47 decades to come. Even before the 2027
00:06:47 --> 00:06:50 Gagan mission, India is preparing to
00:06:50 --> 00:06:52 make history this month when astronaut
00:06:52 --> 00:06:55 Shouansu Shukla becomes the first Indian
00:06:55 --> 00:06:58 to visit the International Space Station
00:06:58 --> 00:07:00 and only the second Indian ever to reach
00:07:00 --> 00:07:03 orbit. Shukla, who is set to pilot the
00:07:03 --> 00:07:06 Axiom mission 4 in a joint NASA ISRO
00:07:06 --> 00:07:08 undertaking, is likely among the top
00:07:08 --> 00:07:11 candidates for ISRO's Gagan spaceflight
00:07:11 --> 00:07:12 program.
00:07:12 --> 00:07:15 This upcoming ISS mission comes four
00:07:15 --> 00:07:17 decades after India's Rakesh Chararma's
00:07:17 --> 00:07:19 historic space flight aboard a Russian
00:07:19 --> 00:07:22 spacecraft in 1984, highlighting just
00:07:22 --> 00:07:24 how far India's independent space
00:07:24 --> 00:07:27 capabilities have advanced since then.
00:07:27 --> 00:07:28 Through these carefully planned
00:07:28 --> 00:07:31 missions, India is establishing itself
00:07:31 --> 00:07:32 not just as a participant in space
00:07:33 --> 00:07:35 exploration, but increasingly as a
00:07:35 --> 00:07:37 leader in developing innovative,
00:07:37 --> 00:07:39 costeffective approaches to reaching
00:07:39 --> 00:07:41 beyond Earth.
00:07:42 --> 00:07:44 Next on our news agenda, Strataunch has
00:07:44 --> 00:07:46 finally discovered a perfect application
00:07:46 --> 00:07:48 for the world's largest airplane, making
00:07:48 --> 00:07:50 significant progress in the field of
00:07:50 --> 00:07:52 hypersonic flight testing. Twice in
00:07:52 --> 00:07:54 recent months, the company successfully
00:07:54 --> 00:07:56 launched its Talon A2 vehicle over the
00:07:56 --> 00:07:59 Pacific Ocean, accelerated it to more
00:07:59 --> 00:08:01 than five times the speed of sound, and
00:08:01 --> 00:08:05 most impressively landed it autonomously
00:08:05 --> 00:08:06 at Vandenberg Space Force Base in
00:08:06 --> 00:08:09 California. What's remarkable is that
00:08:09 --> 00:08:11 they use the same vehicle for both
00:08:11 --> 00:08:13 December and March flights,
00:08:13 --> 00:08:15 demonstrating the systems
00:08:15 --> 00:08:17 reusability. This achievement represents
00:08:17 --> 00:08:19 a historic milestone as the first time
00:08:19 --> 00:08:22 in 60 years that anyone in the United
00:08:22 --> 00:08:24 States has flown a reusable hypersonic
00:08:24 --> 00:08:26 rocket plane since the final flight of
00:08:26 --> 00:08:29 the iconic X-15 back in
00:08:29 --> 00:08:32 1968. But whereas the X-15 required a
00:08:32 --> 00:08:33 human pilot, the Talon A flies
00:08:33 --> 00:08:36 completely autonomously. Zachary Krever,
00:08:36 --> 00:08:38 Strataunch's CEO, explained the
00:08:38 --> 00:08:40 significance of this autonomous
00:08:40 --> 00:08:43 capability. Hypersonic systems are now
00:08:43 --> 00:08:44 pushing the envelope in terms of
00:08:44 --> 00:08:46 maneuvering capability. Maneuvering
00:08:46 --> 00:08:48 beyond what can be done by the human
00:08:48 --> 00:08:51 body. Being able to perform flights with
00:08:51 --> 00:08:54 an autonomous reusable hypersonic test
00:08:54 --> 00:08:56 bed ensures that these flights are
00:08:56 --> 00:08:58 exploring the full envelope of
00:08:58 --> 00:08:59 capability that represents what's
00:08:59 --> 00:09:01 occurring in hypersonic system
00:09:01 --> 00:09:04 development today. The Talon, which is
00:09:04 --> 00:09:06 about half the size of the X-15 and a
00:09:06 --> 00:09:08 little smaller than a school bus,
00:09:08 --> 00:09:10 conducted these flights under contract
00:09:10 --> 00:09:13 with defense contractor LOS as part of
00:09:13 --> 00:09:15 the Pentagon's multi-service advanced
00:09:15 --> 00:09:18 capability hypersonics test bed program
00:09:18 --> 00:09:21 known as MAC TB. This program aims to
00:09:21 --> 00:09:23 dramatically increase America's
00:09:23 --> 00:09:25 hypersonic testing capabilities. George
00:09:25 --> 00:09:28 Rumford, director of the test resource
00:09:28 --> 00:09:30 management center, emphasized the
00:09:30 --> 00:09:32 importance of these tests. Demonstrating
00:09:32 --> 00:09:34 the reuse of fully recoverable
00:09:34 --> 00:09:36 hypersonic test vehicles is an important
00:09:36 --> 00:09:38 milestone. Lessons learned from this
00:09:38 --> 00:09:40 test campaign will help us reduce
00:09:40 --> 00:09:42 vehicle turnaround time from months down
00:09:42 --> 00:09:45 to weeks. He said this progress is
00:09:45 --> 00:09:47 particularly important as the United
00:09:47 --> 00:09:49 States works to catch up with China,
00:09:49 --> 00:09:51 which US officials acknowledge has
00:09:51 --> 00:09:53 become the world leader in hypersonic
00:09:53 --> 00:09:56 missile development. Hypersonic weapons
00:09:56 --> 00:09:59 fly at speeds exceeding Mach 5 and are
00:09:59 --> 00:10:01 significantly more difficult for aerial
00:10:01 --> 00:10:03 defense systems to detect, track, and
00:10:03 --> 00:10:05 destroy than conventional missiles.
00:10:05 --> 00:10:08 Unlike ballistic missiles, hypersonic
00:10:08 --> 00:10:09 weapons ride at the top of the
00:10:09 --> 00:10:11 atmosphere, enhancing their
00:10:11 --> 00:10:14 maneuverability and ability to evade
00:10:14 --> 00:10:16 interceptors. The hypersonic flight
00:10:16 --> 00:10:18 environment is incredibly challenging
00:10:18 --> 00:10:20 with temperatures outside the Talon A
00:10:20 --> 00:10:23 reaching up to 2° F as it moves
00:10:23 --> 00:10:25 through the atmosphere. During its
00:10:25 --> 00:10:27 journey from release point to landing,
00:10:27 --> 00:10:29 the vehicle performed a series of high G
00:10:29 --> 00:10:31 maneuvers, further demonstrating its
00:10:31 --> 00:10:33 capabilities. Strata Launch is now
00:10:33 --> 00:10:36 building a second rocket plane, Talon
00:10:36 --> 00:10:38 A3, scheduled to enter service later
00:10:38 --> 00:10:40 this year. It will launch from a Boeing
00:10:40 --> 00:10:43 747 carrier aircraft that Strataunch
00:10:43 --> 00:10:46 acquired from Virgin Orbit after its
00:10:46 --> 00:10:49 bankruptcy in 2023. The longer range of
00:10:49 --> 00:10:53 the 747 will allow the company to stage
00:10:53 --> 00:10:55 hypersonic tests from additional
00:10:55 --> 00:10:58 locations beyond the West Coast. With
00:10:58 --> 00:11:00 the Pentagon aiming to increase
00:11:00 --> 00:11:02 hypersonic flight tests from 12 to 50
00:11:02 --> 00:11:04 per year, Strata Launch's technology
00:11:04 --> 00:11:06 represents a crucial capability in
00:11:06 --> 00:11:08 America's efforts to advance hypersonic
00:11:08 --> 00:11:11 research and development. The company
00:11:11 --> 00:11:13 hopes to achieve monthly flights by the
00:11:13 --> 00:11:15 end of this year and eventually ramp up
00:11:15 --> 00:11:17 to weekly testing missions.
00:11:18 --> 00:11:20 Well, the JWST has done it again. The
00:11:20 --> 00:11:22 James Webb Space Telescope has given
00:11:22 --> 00:11:24 astronomers an unprecedented view into
00:11:24 --> 00:11:26 the atmospheres of a fascinating pair of
00:11:26 --> 00:11:29 brown dwarfs, providing what scientists
00:11:29 --> 00:11:30 are calling a weather report from our
00:11:30 --> 00:11:33 cosmic neighborhood. The objects in
00:11:33 --> 00:11:34 question are
00:11:34 --> 00:11:39 wise, 149AB, also known as lumen 16,
00:11:39 --> 00:11:41 which sit just 6.5 light years away from
00:11:41 --> 00:11:43 Earth, making them the closest and
00:11:43 --> 00:11:46 brightest brown dwarfs we know of. Brown
00:11:46 --> 00:11:49 dwarfs occupy a curious middle ground in
00:11:49 --> 00:11:52 astronomical classification. Too massive
00:11:52 --> 00:11:53 to be considered planets, but not quite
00:11:54 --> 00:11:55 massive enough to sustain the hydrogen
00:11:55 --> 00:11:58 fusion that powers stars. This makes
00:11:58 --> 00:12:00 them extremely valuable for scientists
00:12:00 --> 00:12:02 trying to understand both exoplanet
00:12:02 --> 00:12:06 atmospheres and stellar dynamics. They
00:12:06 --> 00:12:07 essentially serve as perfect
00:12:07 --> 00:12:09 laboratories for studying atmospheric
00:12:09 --> 00:12:12 behavior in extreme environments. The
00:12:12 --> 00:12:15 new observations use the JWST's NERS
00:12:15 --> 00:12:17 spec and MIRER instruments to monitor
00:12:17 --> 00:12:19 these brown dwarfs over an extended
00:12:19 --> 00:12:21 period, creating the longest baseline
00:12:21 --> 00:12:23 weather monitoring for any brown dwarf
00:12:23 --> 00:12:25 to date. What makes this study
00:12:25 --> 00:12:27 particularly groundbreaking is that
00:12:27 --> 00:12:28 researchers were able to observe
00:12:28 --> 00:12:31 wavelengths beyond 11 micrometers,
00:12:31 --> 00:12:33 reaching up to 14 micrometers, for the
00:12:33 --> 00:12:36 first time ever in brown dwarf research.
00:12:36 --> 00:12:38 This expanded wavelength range allowed
00:12:38 --> 00:12:40 scientists to capture both the upper and
00:12:40 --> 00:12:42 lower atmospheric layers of these
00:12:42 --> 00:12:44 objects, revealing dramatic weather
00:12:44 --> 00:12:46 patterns and the behavior of small
00:12:46 --> 00:12:48 silicut particles that form cloud layers
00:12:48 --> 00:12:50 in their atmospheres. The observations
00:12:50 --> 00:12:52 show striking light curve shapes in the
00:12:52 --> 00:12:54 deepest atmospheric layers, which
00:12:54 --> 00:12:56 researchers attribute to patchy cloud
00:12:56 --> 00:12:58 formations. higher in the atmospheres
00:12:58 --> 00:13:01 between wavelengths of 2.5 to 8.5
00:13:01 --> 00:13:03 micrometers. The team identified hot
00:13:03 --> 00:13:06 spots caused by temperature and chemical
00:13:06 --> 00:13:07 variations of molecules like carbon
00:13:08 --> 00:13:10 monoxide and methane. Perhaps most
00:13:10 --> 00:13:12 intriguingly, they found evidence that
00:13:12 --> 00:13:14 small grain silicates contribute to the
00:13:14 --> 00:13:16 atmospheric variability in one of the
00:13:16 --> 00:13:19 brown dwarfs, but not in its companion.
00:13:19 --> 00:13:21 Since brown dwarfs are fast rotators
00:13:21 --> 00:13:23 that complete rotations in just hours,
00:13:23 --> 00:13:25 these timeresolved studies allow
00:13:25 --> 00:13:26 astronomers to capture the
00:13:26 --> 00:13:29 inconsistencies in their atmospheres and
00:13:29 --> 00:13:31 understand the mechanisms driving these
00:13:31 --> 00:13:33 changes. The research team concluded
00:13:33 --> 00:13:35 that while different atmospheric layers
00:13:35 --> 00:13:37 are governed by different mechanisms,
00:13:37 --> 00:13:39 each variability mechanism remains
00:13:39 --> 00:13:41 consistent within its layer over the
00:13:41 --> 00:13:44 long term. This work represents a major
00:13:44 --> 00:13:46 step forward in our understanding of
00:13:46 --> 00:13:47 ultracoolled atmospheres and will help
00:13:47 --> 00:13:50 inform studies of exoplanet atmospheres,
00:13:50 --> 00:13:51 potentially aiding in the search for
00:13:52 --> 00:13:53 habitable worlds and possible bio
00:13:53 --> 00:13:56 signatures. Scientists plan to expand
00:13:56 --> 00:13:58 JWST variability surveys across more
00:13:58 --> 00:14:00 brown dwarfs to trace and understand
00:14:00 --> 00:14:02 these mechanisms across a wider
00:14:02 --> 00:14:04 population of
00:14:04 --> 00:14:06 objects. Finally, today something a
00:14:06 --> 00:14:08 little different.
00:14:08 --> 00:14:09 Space enthusiasts and LEGO builders
00:14:10 --> 00:14:11 alike have something extraordinary to
00:14:11 --> 00:14:13 look forward to this month as LEGO has
00:14:13 --> 00:14:16 unveiled its newest icon set. A
00:14:16 --> 00:14:18 meticulously detailed recreation of
00:14:18 --> 00:14:21 NASA's 747 shuttle carrier aircraft with
00:14:21 --> 00:14:24 the prototype orbiter Enterprise perched
00:14:24 --> 00:14:26 a top. This impressive model captures
00:14:26 --> 00:14:29 the iconic duo exactly as they appeared
00:14:29 --> 00:14:32 during their historic 1983 International
00:14:32 --> 00:14:34 Goodwill Tour, which included memorable
00:14:34 --> 00:14:36 stops at the Paris Air Show and visits
00:14:36 --> 00:14:40 to Italy, England, Iceland, and Canada.
00:14:40 --> 00:14:41 The
00:14:41 --> 00:14:44 $229.99 building kit will first become
00:14:44 --> 00:14:47 available to LEGO Insiders Loyalty Club
00:14:47 --> 00:14:49 members on May 15th, with a wider
00:14:49 --> 00:14:51 release in LEGO stores across the United
00:14:51 --> 00:14:54 States and Europe following on May 18th.
00:14:54 --> 00:14:56 The release date is particularly
00:14:56 --> 00:14:59 fitting, coming just 42 years and 1 day
00:14:59 --> 00:15:01 after the real aircraft and orbiter
00:15:01 --> 00:15:02 first departed from Southern California
00:15:02 --> 00:15:05 to begin their tour. Comprised of
00:15:05 --> 00:15:08 2417 pieces, the assembled model is
00:15:08 --> 00:15:11 truly impressive in scale. Measuring
00:15:11 --> 00:15:13 over 2 feet long with a wingspan of 21
00:15:13 --> 00:15:17 in and standing nearly 11 in tall. LEGO
00:15:17 --> 00:15:18 has packed this set with authentic
00:15:18 --> 00:15:20 details and functional features,
00:15:20 --> 00:15:23 including retractable landing gear and
00:15:23 --> 00:15:25 the specialized mounting system that
00:15:25 --> 00:15:26 secured the shuttle to the aircraft's
00:15:26 --> 00:15:29 back. The Enterprise model itself
00:15:29 --> 00:15:31 includes several notable features such
00:15:31 --> 00:15:33 as an attachable tail cone used to
00:15:33 --> 00:15:35 improve aerodynamics when flying a top
00:15:35 --> 00:15:36 the
00:15:36 --> 00:15:39 747, detachable main engines, and
00:15:39 --> 00:15:40 landing gear that can be tucked inside
00:15:40 --> 00:15:43 its payload bay. LEGO has even included
00:15:44 --> 00:15:46 the distinctive 376 marking that was
00:15:46 --> 00:15:49 added to the 747 before its appearance
00:15:49 --> 00:15:52 at the Paris Air Show. For display
00:15:52 --> 00:15:54 purposes, the set comes with pieces to
00:15:54 --> 00:15:56 build a sturdy stand and information
00:15:56 --> 00:15:58 plaques highlighting facts about these
00:15:58 --> 00:16:00 historic vehicles. This isn't LEGO's
00:16:00 --> 00:16:02 first attempt at recreating this famous
00:16:02 --> 00:16:05 aircraft combination. A much simpler
00:16:05 --> 00:16:08 342piece version was released back in
00:16:08 --> 00:16:10 1995, but the new Icons version
00:16:10 --> 00:16:12 represents an extraordinary leap forward
00:16:12 --> 00:16:15 in detail and accuracy. The shuttle
00:16:15 --> 00:16:17 carrier aircraft set joins Lego's 2021
00:16:17 --> 00:16:19 space shuttle Discovery in the Icons
00:16:19 --> 00:16:22 line. Continuing the company's tradition
00:16:22 --> 00:16:24 of creating museum quality models of
00:16:24 --> 00:16:26 NASA's most famous spacecraft for adult
00:16:26 --> 00:16:28 builders and
00:16:28 --> 00:16:30 collectors. That wraps up today's
00:16:30 --> 00:16:32 episode of Astronomy Daily. From
00:16:32 --> 00:16:34 SpaceX's expanded launch capabilities in
00:16:34 --> 00:16:36 Texas to India's ambitious plans for
00:16:36 --> 00:16:38 human space flight, from Strata Launch's
00:16:38 --> 00:16:41 groundbreaking hypersonic test flights
00:16:41 --> 00:16:43 to web's fascinating observations of
00:16:43 --> 00:16:45 brown dwarf weather patterns, and
00:16:45 --> 00:16:47 finally to that spectacular LEGO
00:16:47 --> 00:16:49 recreation of NASA's shuttle carrier
00:16:49 --> 00:16:51 aircraft. We've traveled across the
00:16:51 --> 00:16:54 solar system and back with today's news.
