AnnaAnnaHost
Welcome to Astronomy Daily! Join hosts Anna and Avery as they explore today's most fascinating space and astronomy stories.
IN THIS EPISODE:
🌌 NASA's Dark Matter Map
NASA's James Webb Space Telescope has created one of the most detailed dark matter maps ever produced, revealing the invisible scaffolding of the universe in unprecedented detail. Scientists mapped nearly 800,000 galaxies, showing how dark matter and regular matter have grown together throughout cosmic history - and how dark matter's influence may have been essential for creating the conditions necessary for life on Earth.
🚀 Weekly Launch Roundup
A busy week in orbital spaceflight with multiple missions planned from Florida, California, and New Zealand. SpaceX prepares to launch GPS III SV09 named after fallen Challenger astronaut Ellison Onizuka, while Rocket Lab readies its "Bridging the Swarm" mission carrying South Korea's NeonSat-1A satellite. Plus updates on multiple Starlink flights and possible Chinese launches.
🌙 Artemis II's Far Side Adventure
The Artemis II crew - Reid Wiseman, Victor Glover, Christina Hammock Koch, and Jeremy Hansen - are training to become the first humans to see parts of the Moon never before observed by human eyes. Learn about their planned three-hour observation session focusing on Mare Orientale and other hidden lunar features, and how their geology training in Iceland is preparing them for this historic mission.
🪐 Jupiter's Hidden Depths
NASA's Juno spacecraft continues to revolutionize our understanding of Jupiter, revealing that the planet's iconic cloud bands extend 1,900 miles below the surface. Discover recent findings about Jupiter's diluted core, mysterious green lightning flashes, and the remarkably persistent polar cyclones that form octagonal and pentagonal patterns at the planet's poles.
☀️ Antarctica's Exclusive Eclipse
Only about 16 people might witness one of 2026's most spectacular celestial events - a "ring of fire" annular solar eclipse crossing Antarctica on February 17th. Find out about the two research stations in the path of totality, the extreme conditions observers will face, and where else partial views of the eclipse will be visible.
🛸 Starship V3 Update
SpaceX's upgraded Starship rocket test has been rescheduled for mid-March following a November explosion during testing. Learn about the new capabilities of Starship V3, including plans to launch next-generation Starlink satellites and dock with other Starships in orbit - plus how Blue Origin's New Glenn is emerging as competition in the heavy-lift market.

00:00:00 --> 00:00:03 Anna: Welcome to Astronomy Daily, your source for

00:00:03 --> 00:00:06 the latest space and astronomy news. I'm

00:00:06 --> 00:00:06 Anna.

00:00:06 --> 00:00:09 Avery: And I'm avery. Today's Tuesday, January

00:00:09 --> 00:00:12 27, 2026, and we've got some

00:00:12 --> 00:00:14 fascinating stories lined up for you.

00:00:14 --> 00:00:17 Anna: We certainly do. On today's episode, we're

00:00:17 --> 00:00:20 diving into NASA's groundbreaking new Dark

00:00:20 --> 00:00:23 matter map, getting the latest updates on

00:00:23 --> 00:00:25 this week's orbital launch schedule, and

00:00:25 --> 00:00:28 learning about what the Artemis II crew might

00:00:28 --> 00:00:29 see on the far side of the Moon.

00:00:30 --> 00:00:32 Avery: Plus, we'll explore stun new insights into

00:00:32 --> 00:00:35 Jupiter's complex cloud systems,

00:00:35 --> 00:00:38 find out about a rare solar eclipse that only

00:00:38 --> 00:00:40 a handful of people will witness, and get the

00:00:40 --> 00:00:43 latest on SpaceX's upgraded Starship

00:00:43 --> 00:00:43 development.

00:00:44 --> 00:00:44 Anna: Let's get started.

00:00:45 --> 00:00:46 Avery: Take it away, Anna.

00:00:46 --> 00:00:49 Anna: Our top story today comes from NASA's

00:00:49 --> 00:00:51 Jet Propulsion Laboratory, where scientists

00:00:51 --> 00:00:54 have created one of the most detailed dark

00:00:54 --> 00:00:57 matter maps ever produced using data from

00:00:57 --> 00:00:59 the James Webb Space Telescope.

00:00:59 --> 00:01:02 Avery: This is really exciting stuff, Anna. Uh, the

00:01:02 --> 00:01:04 map shows how dark matter, that invisible,

00:01:05 --> 00:01:07 ghostly material that makes up most of the

00:01:07 --> 00:01:09 universe's mass, overlaps and

00:01:09 --> 00:01:12 intertwines with regular matter like stars

00:01:12 --> 00:01:13 and galaxies.

00:01:13 --> 00:01:16 Anna: Published Monday in Nature Astronomy, this

00:01:16 --> 00:01:19 map is twice as sharp as any previous

00:01:19 --> 00:01:22 dark matter map made by other observatories.

00:01:22 --> 00:01:25 Diana Skogni Aglio, the lead author and

00:01:25 --> 00:01:28 astrophysicist at jpl, described it

00:01:28 --> 00:01:30 as seeing the invisible scaffolding of the

00:01:30 --> 00:01:33 universe in stunning detail for the first

00:01:33 --> 00:01:33 time.

00:01:33 --> 00:01:36 Avery: What's particularly fascinating is how the

00:01:36 --> 00:01:38 map confirms that dark matter and regular

00:01:38 --> 00:01:41 matter have essentially grown up together.

00:01:41 --> 00:01:44 Wherever you see a massive cluster of

00:01:44 --> 00:01:46 thousands of galaxies, there's an equally

00:01:46 --> 00:01:49 massive amount of dark matter in the same

00:01:49 --> 00:01:51 place. When you see strings of regular matter

00:01:51 --> 00:01:54 connecting clusters, dark matter strings are

00:01:54 --> 00:01:55 there, too.

00:01:55 --> 00:01:58 Anna: The team used Webb's unprecedented

00:01:58 --> 00:02:00 sensitivity to observe nearly

00:02:00 --> 00:02:02 800 galaxies in a region of

00:02:02 --> 00:02:05 SK about 2.5 times larger

00:02:05 --> 00:02:08 than the Full Moon. They detected dark matter

00:02:08 --> 00:02:11 by observing how its mass curves space

00:02:11 --> 00:02:14 itself, which bends light from distant

00:02:14 --> 00:02:16 galaxies as it travels to Earth.

00:02:16 --> 00:02:18 Avery: Here's something to ponder. Without dark

00:02:18 --> 00:02:21 matter, we might not even be here. Dark

00:02:21 --> 00:02:24 matter began clumping together first in the

00:02:24 --> 00:02:27 early universe, and those clumps then pulled

00:02:27 --> 00:02:29 regular matter together, creating the

00:02:29 --> 00:02:31 conditions for stars and galaxies to form

00:02:32 --> 00:02:33 earlier than they would have otherwise.

00:02:34 --> 00:02:36 Anna: That earlier star formation was crucial

00:02:36 --> 00:02:39 because those first generations of stars

00:02:39 --> 00:02:41 turned hydrogen and helium into the rich

00:02:41 --> 00:02:44 array of elements that now make up planets

00:02:44 --> 00:02:47 like Earth. So in a very real sense,

00:02:47 --> 00:02:50 dark matter influenced the creation of the

00:02:50 --> 00:02:51 elements necessary for life.

00:02:52 --> 00:02:55 Avery: Looking ahead, the upcoming Nancy Grace Roman

00:02:55 --> 00:02:58 Space Telescope will map dark matter over

00:02:58 --> 00:03:01 an area 4 times bigger than this

00:03:01 --> 00:03:04 Webb study, though it won't match Webb's

00:03:04 --> 00:03:06 incredible resolution. For even more

00:03:06 --> 00:03:08 detailed looks, we'll have to wait for next

00:03:08 --> 00:03:11 generation telescopes like the proposed

00:03:11 --> 00:03:12 Habitable Worlds Observatory.

00:03:13 --> 00:03:15 Anna: Fascinating research that's literally

00:03:15 --> 00:03:18 revealing the invisible foundation of our

00:03:18 --> 00:03:18 universe.

00:03:19 --> 00:03:21 Avery: Moving on to this week's launch schedule,

00:03:21 --> 00:03:23 it's shaping up to be, uh, a busy last week

00:03:23 --> 00:03:25 of January with flights from Florida,

00:03:25 --> 00:03:28 California and New Zealand on the manifesto.

00:03:29 --> 00:03:31 Anna: That's right, SpaceX is planning to close out

00:03:31 --> 00:03:33 the month with the GPS 3

00:03:34 --> 00:03:36 SV09 mission along with up to three

00:03:36 --> 00:03:39 Starlink launches. The GPS launch is

00:03:39 --> 00:03:42 scheduled for late Monday evening from cape

00:03:42 --> 00:03:42 Canaveral.

00:03:43 --> 00:03:45 Avery: The GPS 3 SV09

00:03:45 --> 00:03:48 satellite, named Ellison Onisuka after one of

00:03:48 --> 00:03:51 the fallen Challenger astronauts, will be

00:03:51 --> 00:03:53 launched to medium Earth orbit. This

00:03:53 --> 00:03:56 spacecraft offers improved accuracy and

00:03:56 --> 00:03:58 jamming resistance over previous versions of

00:03:58 --> 00:03:59 gps.

00:03:59 --> 00:04:02 Anna: Meanwhile, Rocket Labs ELECTRON is preparing

00:04:02 --> 00:04:04 for the Bridging the Swarm mission from New

00:04:04 --> 00:04:06 Zealand's Mahia Peninsula on Wednesday.

00:04:07 --> 00:04:10 This launch will carry South Korea's Neonsat

00:04:10 --> 00:04:12 1 a observation satellite to sun

00:04:12 --> 00:04:14 synchronous orbit.

00:04:14 --> 00:04:16 Avery: The Neonsat constellation is designed to

00:04:16 --> 00:04:19 provide near real time disaster monitoring

00:04:19 --> 00:04:21 capability for the Korean Peninsula. The

00:04:21 --> 00:04:24 100 kilogram Neonsat 1A features

00:04:24 --> 00:04:27 a high resolution optical camera and will

00:04:27 --> 00:04:30 join an existing NEONSAT satellite already in

00:04:30 --> 00:04:30 orbit.

00:04:30 --> 00:04:33 Anna: This miss already faced a couple of delays.

00:04:33 --> 00:04:35 It was originally scheduled to launch back in

00:04:35 --> 00:04:38 December, but was scrubbed after sensor

00:04:38 --> 00:04:39 issues during Countdown.

00:04:39 --> 00:04:42 Avery: SpaceX also has multiple Starlink missions on

00:04:42 --> 00:04:44 the schedule this week from Both coasts,

00:04:44 --> 00:04:47 Group 1719 from Vandenberg

00:04:47 --> 00:04:49 Space Force Base in California on Thursday,

00:04:50 --> 00:04:53 and Group 6101 from Cape

00:04:53 --> 00:04:54 Canaveral later that same day.

00:04:54 --> 00:04:57 Anna: And looking ahead to early February, the

00:04:57 --> 00:04:59 first Starlink mission of next month, Group

00:04:59 --> 00:05:02 6 103, is currently scheduled

00:05:02 --> 00:05:04 for Sunday, February 1.

00:05:04 --> 00:05:07 Avery: China also has two possible flights on the

00:05:07 --> 00:05:10 manifest a Chang Zhang 7A from

00:05:10 --> 00:05:13 Hainan island and a Jielong 3 from the

00:05:13 --> 00:05:15 South China Sea. Though neither has a

00:05:15 --> 00:05:16 confirmed launch date.

00:05:16 --> 00:05:18 Anna: Yet, it's worth noting that China's year in

00:05:18 --> 00:05:20 spaceflight has already been eventful with

00:05:20 --> 00:05:23 two launch failures within 12 hours in mid

00:05:23 --> 00:05:26 January, so they may be proceeding cautiously

00:05:26 --> 00:05:27 with these upcoming missions.

00:05:28 --> 00:05:31 Okay, moving on, our next story takes us to

00:05:31 --> 00:05:34 preparations for NASA's Artemis 2 mission,

00:05:34 --> 00:05:36 where four astronauts are training to become

00:05:36 --> 00:05:39 the first humans to see parts of the moon

00:05:39 --> 00:05:41 that have remained hidden from view even

00:05:41 --> 00:05:42 during the Apollo missions.

00:05:42 --> 00:05:45 Avery: The Artemis 2 crew Reid Wiseman,

00:05:45 --> 00:05:48 Victor Glover, Christina Hammock Coach, and

00:05:48 --> 00:05:51 Jeremy Hansen won't land on the lunar

00:05:51 --> 00:05:53 surface, but they'll fly around the far side

00:05:53 --> 00:05:56 of the Moon and potentially observe regions

00:05:56 --> 00:05:58 never before seen by human eyes.

00:05:58 --> 00:06:01 Anna: Among the most significant targets is Mari

00:06:01 --> 00:06:04 oriental, a vast 600 mile

00:06:04 --> 00:06:06 wide impact basing that sits along the edge

00:06:06 --> 00:06:09 of the lunar far side. Its location makes it

00:06:09 --> 00:06:12 nearly impossible to view from Earth, despite

00:06:12 --> 00:06:13 its massive scale.

00:06:13 --> 00:06:16 Avery: The crew will spend a dedicated three hour

00:06:16 --> 00:06:18 segment of their mission focusing on direct

00:06:18 --> 00:06:21 lunar observation. NASA exploration

00:06:21 --> 00:06:23 scientist Jacob Bleacher emphasizes that

00:06:23 --> 00:06:26 human vision can detect subtle surface

00:06:26 --> 00:06:28 differences, Variations in brightness or

00:06:28 --> 00:06:31 texture that indicate differences in rock

00:06:31 --> 00:06:33 composition and geological age.

00:06:33 --> 00:06:35 Anna: What's fascinating is that the astronauts

00:06:35 --> 00:06:37 have been training extensively in geology,

00:06:38 --> 00:06:40 including simulated exercises in Iceland

00:06:40 --> 00:06:43 where they practiced identifying volcanic and

00:06:43 --> 00:06:46 impact related features in environments

00:06:46 --> 00:06:47 resembling the Moon.

00:06:47 --> 00:06:49 Avery: The far side of the moon holds a geologic

00:06:49 --> 00:06:52 record less disturbed than the near side.

00:06:52 --> 00:06:54 While much of the near side is covered with

00:06:54 --> 00:06:57 maria, the vast plains of ancient lava that

00:06:57 --> 00:06:59 have erased older surface features, the far

00:06:59 --> 00:07:02 side remains heavily cratered and relatively

00:07:02 --> 00:07:02 intact.

00:07:03 --> 00:07:05 Anna: Because of tidal locking, the moon always

00:07:05 --> 00:07:08 shows the same face to Earth. Until the

00:07:08 --> 00:07:11 Soviet Luna 3 mission in 1959,

00:07:11 --> 00:07:14 no one had any idea what the far side looked

00:07:14 --> 00:07:17 like. Even the Apollo missions only had brief

00:07:17 --> 00:07:18 views and poor lighting.

00:07:18 --> 00:07:21 Avery: Artemis 2 breaks that pattern by taking

00:07:21 --> 00:07:23 advantage of a launch window and flight path

00:07:23 --> 00:07:26 that ensures better visibility of the hidden

00:07:26 --> 00:07:28 hemisphere. The mission is currently

00:07:28 --> 00:07:30 scheduled for no earlier than February 6,

00:07:30 --> 00:07:32 and astronaut Christina.

00:07:32 --> 00:07:34 Anna: Koch noted that the mission may help shift

00:07:34 --> 00:07:37 public understanding away from the outdated

00:07:37 --> 00:07:40 phrase the dark side of the moon, which

00:07:40 --> 00:07:42 falsely implies the region lacks sunlight.

00:07:42 --> 00:07:44 Avery: An exciting mission that will give us

00:07:44 --> 00:07:47 unprecedented views of lunar territory that

00:07:47 --> 00:07:49 remained largely mysterious for all of human

00:07:49 --> 00:07:50 history.

00:07:50 --> 00:07:52 Anna: Now let's turn our attention to Jupiter,

00:07:52 --> 00:07:55 where NASA's Juno spacecraft continues to

00:07:55 --> 00:07:58 reveal the gas giant's secrets from beneath

00:07:58 --> 00:07:59 its dense cloud layers.

00:07:59 --> 00:08:02 Avery: Juno has been orbiting Jupiter since 2016,

00:08:03 --> 00:08:05 peering through storms and cyclones to unveil

00:08:05 --> 00:08:08 the planet's hidden complexity. And recent

00:08:08 --> 00:08:10 observations are showing just how much more

00:08:10 --> 00:08:13 intricate Jupiter is than we ever imagined.

00:08:13 --> 00:08:16 Anna: One of the most fundamental questions

00:08:16 --> 00:08:19 scientists have debated for decades is how

00:08:19 --> 00:08:21 deep Jupiter's distinctive cloud bands

00:08:21 --> 00:08:24 actually go. By measuring Jupiter's

00:08:24 --> 00:08:26 gravity field, Juno discovered that these

00:08:26 --> 00:08:29 belts and zones, which are alternating

00:08:29 --> 00:08:32 east and west flowing jet streams,

00:08:32 --> 00:08:34 extend about 1900 miles,

00:08:34 --> 00:08:37 or 3000 kilometers below the cloud

00:08:37 --> 00:08:38 tops.

00:08:38 --> 00:08:41 Avery: That's incredible depth. And Juno's

00:08:41 --> 00:08:43 discoveries have completely upended our

00:08:43 --> 00:08:46 understanding of Jupiter's interior structure

00:08:46 --> 00:08:49 too. Scientists long thought Jupiter had a

00:08:49 --> 00:08:52 small solid core surrounded by hydrogen and

00:08:52 --> 00:08:54 helium. But Juno's data suggests the

00:08:54 --> 00:08:57 planet has a larger, more diluted core than

00:08:57 --> 00:08:58 previously believed.

00:08:59 --> 00:09:01 Anna: The spacecraft has also provided the first

00:09:01 --> 00:09:04 detailed views of Jupiter's north pole.

00:09:04 --> 00:09:06 Revealing massive cyclonic storms

00:09:06 --> 00:09:09 arranged in fascinating eight

00:09:09 --> 00:09:12 storms in an octagonal pattern in the north

00:09:12 --> 00:09:14 and five in a pentagonal pattern in the

00:09:14 --> 00:09:17 south. These storms are extremely

00:09:17 --> 00:09:19 resilient and have persisted for years.

00:09:20 --> 00:09:22 Avery: And here's something really intriguing.

00:09:22 --> 00:09:25 Juno recently captured images showing a

00:09:25 --> 00:09:27 mysterious green glow near Jupiter's north

00:09:27 --> 00:09:30 pole. The flash of light was traveling at

00:09:30 --> 00:09:33 breakneck speed, which makes capturing it

00:09:33 --> 00:09:34 even more remarkable.

00:09:34 --> 00:09:37 Anna: Scientists believe this could be lightning,

00:09:37 --> 00:09:39 but Jupiter's lightning is vastly different

00:09:39 --> 00:09:42 from Earth's. It's caused by clouds

00:09:42 --> 00:09:45 containing ammonia water solution and can

00:09:45 --> 00:09:47 be much more powerful than terrestrial

00:09:47 --> 00:09:47 lightning.

00:09:47 --> 00:09:50 Avery: Juno's mission has been extended multiple

00:09:50 --> 00:09:53 times and was scheduled to end in September

00:09:53 --> 00:09:56 2025, but appears to still be

00:09:56 --> 00:09:58 operational, with no new end date being

00:09:58 --> 00:10:01 promoted. During this extended phase,

00:10:01 --> 00:10:04 the spacecraft is conducting close

00:10:04 --> 00:10:07 flybys of Jupiter's intriguing Galilean

00:10:07 --> 00:10:09 moons Ganymede, Europa and

00:10:09 --> 00:10:11 IO Eventually, Juno.

00:10:11 --> 00:10:14 Anna: Will meet its end by burning up in Jupiter's

00:10:14 --> 00:10:17 atmosphere. But until then, it continues to

00:10:17 --> 00:10:19 revolutionize our understanding of the solar

00:10:19 --> 00:10:21 system's largest planet.

00:10:22 --> 00:10:24 Avery: Our next story involves a celestial event

00:10:24 --> 00:10:27 that very few people will witness. A

00:10:27 --> 00:10:29 rare annular solar eclipse set to occur

00:10:29 --> 00:10:32 over one of the most remote places on Earth.

00:10:32 --> 00:10:35 Anna: On February 17, 2026,

00:10:35 --> 00:10:38 a spectacular ring of fire eclipse

00:10:38 --> 00:10:41 will be visible from a narrow stretch of

00:10:41 --> 00:10:43 Antarctica. The phenomenon will only be

00:10:43 --> 00:10:46 fully visible from an uninhabited region of

00:10:46 --> 00:10:48 the continent, with just two research

00:10:48 --> 00:10:51 stations falling within the event's path.

00:10:51 --> 00:10:54 Avery: The antumbral shadow of the Moon, the area

00:10:54 --> 00:10:56 where the full annular eclipse can be seen,

00:10:57 --> 00:10:59 will travel across a, uh, 26,

00:10:59 --> 00:11:02 61 mile stretch of mainland

00:11:02 --> 00:11:04 Antarctica. Only two inhabited locations

00:11:05 --> 00:11:07 fall within this narrow Concordia

00:11:07 --> 00:11:10 Station, a AH French Italian base, and

00:11:10 --> 00:11:12 Mirny Station, operated by Russia.

00:11:13 --> 00:11:16 Anna: At Concordia, annularity will last 2

00:11:16 --> 00:11:19 minutes and 1 second with the sun positioned

00:11:19 --> 00:11:21 5 degrees above the horizon. At

00:11:21 --> 00:11:24 Mirny, it will experience 1 minute and

00:11:24 --> 00:11:27 52 seconds of annularity, with the sun

00:11:27 --> 00:11:29 slightly higher at 10 degrees.

00:11:29 --> 00:11:32 Avery: Given the extreme location and limited

00:11:32 --> 00:11:34 infrastructure, eclipse meteorologist Jay

00:11:34 --> 00:11:37 Anderson noted that it's a challenge to

00:11:37 --> 00:11:39 reach, and neither of the two inhabited

00:11:39 --> 00:11:41 locations is set up to welcome Taurus.

00:11:42 --> 00:11:44 Anna: However, a partial eclipse will be visible

00:11:44 --> 00:11:47 over a much larger region, including

00:11:47 --> 00:11:50 several Antarctic research bases, parts of

00:11:50 --> 00:11:53 southeastern Africa, the southern tip of

00:11:53 --> 00:11:55 South America, and stretches of the Pacific,

00:11:55 --> 00:11:57 Atlantic and Indian oceans.

00:11:58 --> 00:12:00 Avery: For example, Poland's AB

00:12:00 --> 00:12:03 Dobrolansky station will see 92%

00:12:03 --> 00:12:06 of the sun covered, while McMurdo station in

00:12:06 --> 00:12:09 the US will see 86%. Even

00:12:09 --> 00:12:11 distant cities like Durban in South Africa

00:12:11 --> 00:12:13 will witness about 16% coverage.

00:12:14 --> 00:12:17 Anna: Weather could be a significant factor, though

00:12:17 --> 00:12:20 mirny station averages 65%

00:12:20 --> 00:12:23 cloud cover in February, while Concordia has

00:12:23 --> 00:12:25 a clearer profile with about 35%

00:12:25 --> 00:12:28 coverage, and temperatures can drop as low

00:12:28 --> 00:12:31 as -112 degrees

00:12:31 --> 00:12:31 Fahrenheit.

00:12:32 --> 00:12:34 Avery: Interestingly, the eclipse itself might

00:12:34 --> 00:12:37 improve viewing conditions. The sudden

00:12:37 --> 00:12:39 temperature drop from the eclipse can disrupt

00:12:39 --> 00:12:42 local cloud formation, potentially causing

00:12:42 --> 00:12:44 convective clouds to dissipate.

00:12:44 --> 00:12:46 Anna: Though if you're one of the handful of

00:12:46 --> 00:12:49 researchers stationed in Antarctica next

00:12:49 --> 00:12:51 month, you might be in for a spectacular

00:12:51 --> 00:12:54 show, assuming the clouds cooperate and

00:12:54 --> 00:12:56 you can brave the extreme cold.

00:12:57 --> 00:12:59 And finally, in some late breaking news, we

00:12:59 --> 00:13:02 have an update on SpaceX's Starship

00:13:02 --> 00:13:03 development program.

00:13:03 --> 00:13:06 Avery: According to a post from CEO Elon Musk, the

00:13:06 --> 00:13:09 delayed first test of SpaceX's upgraded

00:13:09 --> 00:13:12 Starship rocket, version 3, is now

00:13:12 --> 00:13:13 slated for mid March.

00:13:14 --> 00:13:17 Anna: This third version of Starship is larger and

00:13:17 --> 00:13:19 more powerful than previous iterations.

00:13:19 --> 00:13:22 Crucially, SpaceX plans to use

00:13:22 --> 00:13:24 Starship V3 to launch its next

00:13:24 --> 00:13:27 generation Starlink satellites, which will be

00:13:27 --> 00:13:30 capable of faster data speeds but are heavier

00:13:30 --> 00:13:31 and larger.

00:13:31 --> 00:13:33 Avery: It's also the first version designed to dock

00:13:33 --> 00:13:36 with other starships in Earth orbit, a

00:13:36 --> 00:13:38 capability the company needs to reach the

00:13:38 --> 00:13:41 Moon or Mars. This comes as SpaceX

00:13:41 --> 00:13:43 faces pressure from the Trump administration

00:13:43 --> 00:13:46 to return US astronauts to the lunar surface

00:13:46 --> 00:13:48 before the end of a second term.

00:13:48 --> 00:13:51 Anna: SpaceX was making progress toward a launch of

00:13:51 --> 00:13:54 Starship V3 in late 2025,

00:13:54 --> 00:13:57 but in November, the booster stage suffered a

00:13:57 --> 00:14:00 major explosion during testing that blew out

00:14:00 --> 00:14:02 an entire side of the steel rocket.

00:14:02 --> 00:14:05 Avery: The company said it was performing gas system

00:14:05 --> 00:14:07 pressure testing when the explosion happened,

00:14:07 --> 00:14:09 but hasn't offered a more detailed breakdown

00:14:09 --> 00:14:10 of what went wrong.

00:14:11 --> 00:14:13 Anna: The second version of Starship was a mixed

00:14:13 --> 00:14:16 bag. The program successfully reached orbit,

00:14:16 --> 00:14:19 deployed dummy versions of next generation

00:14:19 --> 00:14:21 Starlink satellites, and caught multiple

00:14:21 --> 00:14:24 booster stages after they returned to the

00:14:24 --> 00:14:24 launch pad.

00:14:25 --> 00:14:28 Avery: But Starship V2 also suffered several

00:14:28 --> 00:14:30 explosions and setbacks. Some resulted from

00:14:30 --> 00:14:33 SpaceX's developmental approach of pushing

00:14:33 --> 00:14:36 test vehicles to or past their limits.

00:14:36 --> 00:14:38 Others were more unexpected, like when a

00:14:38 --> 00:14:40 starship vehicle erupted in a massive

00:14:40 --> 00:14:42 fireball during ground testing last June.

00:14:43 --> 00:14:46 Anna: Meanwhile, competition is emerging. Jeff

00:14:46 --> 00:14:48 Bezos's new Glenn rocket successfully

00:14:48 --> 00:14:50 launched for the first time in January

00:14:51 --> 00:14:53 2025 and completed its first

00:14:53 --> 00:14:56 booster landing in November. Blue Origin

00:14:56 --> 00:14:59 is planning a third new Glenn launch in late

00:14:59 --> 00:15:01 February and ah.

00:15:01 --> 00:15:03 Avery: Late last year, Blue Origin revealed it's

00:15:03 --> 00:15:06 developing a larger super heavy variant of

00:15:06 --> 00:15:08 new Glenn M, which more directly compare

00:15:08 --> 00:15:09 competes with starship.

00:15:09 --> 00:15:12 Anna: So while SpaceX continues to dominate the

00:15:12 --> 00:15:15 global launch market, other players are

00:15:15 --> 00:15:17 starting to close the gap. It'll be

00:15:17 --> 00:15:20 interesting to see how the Starship V3 test

00:15:20 --> 00:15:21 goes in March, and.

00:15:21 --> 00:15:24 Avery: That wraps up today's episode of Astronomy

00:15:24 --> 00:15:24 Daily.
