00:00:00 --> 00:00:02 today on astronomy daily we've got a
00:00:02 --> 00:00:04 packed show covering some of the biggest
00:00:04 --> 00:00:07 stories in space news from potential
00:00:07 --> 00:00:09 leadership changes at Nasa that could
00:00:09 --> 00:00:11 reshape the future of American space
00:00:11 --> 00:00:14 exploration to ancient Cosmic collisions
00:00:14 --> 00:00:17 that rocked our planet millions of years
00:00:17 --> 00:00:19 ago we'll also explore fascinating new
00:00:19 --> 00:00:21 developments in Space Telescope
00:00:21 --> 00:00:24 maintenance get an update on Europe's
00:00:24 --> 00:00:26 return to the Launchpad with Vega CA and
00:00:26 --> 00:00:28 discover what the James web Space
00:00:28 --> 00:00:30 Telescope has revealed of about a
00:00:30 --> 00:00:33 mysterious Cosmic spiderweb billions of
00:00:33 --> 00:00:36 light years away plus we'll look at how
00:00:36 --> 00:00:38 our Sun's increasing activity is causing
00:00:38 --> 00:00:40 unexpected challenges for satellites in
00:00:40 --> 00:00:42 orbit and why this could be just the
00:00:42 --> 00:00:44 beginning of a solar storm season that's
00:00:44 --> 00:00:47 already exceeding predictions let's get
00:00:47 --> 00:00:50 started in a significant announcement
00:00:50 --> 00:00:51 that sending ripples through the space
00:00:51 --> 00:00:54 Community president-elect Donald Trump
00:00:54 --> 00:00:57 has named Jared ISAC man as his pick to
00:00:57 --> 00:00:58 lead
00:00:58 --> 00:01:01 NASA this choice marks a notable
00:01:01 --> 00:01:02 departure from traditional NASA
00:01:02 --> 00:01:05 leadership as Isaac man brings a unique
00:01:05 --> 00:01:07 blend of private sector experience and
00:01:07 --> 00:01:09 actual space flight expertise to the
00:01:09 --> 00:01:13 table Isaac man the 41-year-old CEO of
00:01:13 --> 00:01:15 Shift 4 payments has already made his
00:01:15 --> 00:01:17 Mark in space history as a private
00:01:17 --> 00:01:19 astronaut having completed two missions
00:01:19 --> 00:01:22 to orbit aboard SpaceX capsules through
00:01:22 --> 00:01:24 his Polaris program what makes this
00:01:24 --> 00:01:26 selection particularly interesting is
00:01:26 --> 00:01:28 Isaac man's close business relationship
00:01:28 --> 00:01:31 with Elon Musk and space SPX where he's
00:01:31 --> 00:01:33 invested hundreds of millions of dollars
00:01:33 --> 00:01:35 as a key customer of their private
00:01:35 --> 00:01:36 astronaut
00:01:36 --> 00:01:38 Services if confirmed by the Senate
00:01:38 --> 00:01:40 Isaac man would oversee NASA's
00:01:40 --> 00:01:42 substantial $25 billion budget this
00:01:43 --> 00:01:44 appointment comes at a crucial time for
00:01:44 --> 00:01:47 the agency as it continues its ambitious
00:01:47 --> 00:01:49 emis program aimed at returning humans
00:01:49 --> 00:01:51 to the Moon a program that heavily
00:01:51 --> 00:01:54 relies on spacex's Starship vehicle the
00:01:54 --> 00:01:55 timing of this announcement is unusually
00:01:56 --> 00:01:57 early in the presidential transition
00:01:57 --> 00:02:00 process and Industry Insiders note that
00:02:00 --> 00:02:02 musk's influence and discussions about
00:02:02 --> 00:02:04 Mars exploration may have played a role
00:02:04 --> 00:02:07 in this early selection Trump himself
00:02:07 --> 00:02:09 recently attended spacex's sixth
00:02:09 --> 00:02:11 Starship test launch in Texas
00:02:11 --> 00:02:13 highlighting the growing ties between
00:02:13 --> 00:02:15 his potential future Administration and
00:02:15 --> 00:02:18 the commercial space sector Isaac man's
00:02:18 --> 00:02:20 appointment could signal a deeper shift
00:02:20 --> 00:02:22 toward commercialization of space
00:02:22 --> 00:02:24 activities potentially accelerating
00:02:24 --> 00:02:26 NASA's existing strategy of partnering
00:02:26 --> 00:02:29 with private companies this approach has
00:02:29 --> 00:02:31 already trans formed how NASA accesses
00:02:31 --> 00:02:33 space though it has raised questions
00:02:33 --> 00:02:35 about the future of traditional
00:02:35 --> 00:02:37 government-led programs like the space
00:02:37 --> 00:02:40 launch system looking ahead Isaac man
00:02:40 --> 00:02:41 has expressed his vision for expanding
00:02:41 --> 00:02:44 space exploration emphasizing potential
00:02:44 --> 00:02:46 breakthroughs in manufacturing
00:02:46 --> 00:02:48 biotechnology and even new energy
00:02:48 --> 00:02:51 sources however he'll face significant
00:02:51 --> 00:02:53 challenges including managing NASA's
00:02:53 --> 00:02:55 diverse portfolio of scientific missions
00:02:55 --> 00:02:57 some of which have faced recent budget
00:02:57 --> 00:03:00 constraints and balancing the agen
00:03:00 --> 00:03:02 traditional role with increasing
00:03:02 --> 00:03:03 commercial
00:03:03 --> 00:03:05 Partnerships while we often think of the
00:03:05 --> 00:03:07 dinosaur killing asteroid as Earth's
00:03:07 --> 00:03:10 most famous Cosmic impact our planet has
00:03:10 --> 00:03:11 faced other massive collisions
00:03:11 --> 00:03:14 throughout its history a fascinating new
00:03:14 --> 00:03:16 study has revealed that Earth was struck
00:03:16 --> 00:03:19 by not one but two enormous asteroids
00:03:19 --> 00:03:22 around 35 million years ago but here's
00:03:22 --> 00:03:24 the surprising part despite their
00:03:24 --> 00:03:25 tremendous size these impacts left
00:03:26 --> 00:03:28 remarkably little long-term evidence of
00:03:28 --> 00:03:30 climate change the first asteroid
00:03:30 --> 00:03:33 estimated to be between 5 and 8 km wide
00:03:33 --> 00:03:35 created the massive popy crater in
00:03:35 --> 00:03:39 Siberia spanning 100 kilm just 25
00:03:39 --> 00:03:42 years later a second asteroid measuring
00:03:42 --> 00:03:44 3 to 5 kilm struck what is now
00:03:44 --> 00:03:46 Chesapeake Bay in the United States
00:03:46 --> 00:03:49 leaving a crater between 40 and 85 km
00:03:49 --> 00:03:52 wide these aren't minor dents they
00:03:52 --> 00:03:54 represent the fourth and fifth largest
00:03:54 --> 00:03:57 known impact craters on earth scientists
00:03:57 --> 00:03:59 studying these ancient impacts made an
00:03:59 --> 00:04:01 unexpected Discovery when examining
00:04:01 --> 00:04:03 fossil records from the Gulf of Mexico
00:04:03 --> 00:04:06 seaf despite the enormous size of these
00:04:06 --> 00:04:08 collisions they found no significant
00:04:09 --> 00:04:11 evidence of long-term climate change in
00:04:11 --> 00:04:13 the geological record the Earth
00:04:13 --> 00:04:15 essentially Shrugged off these Cosmic
00:04:15 --> 00:04:18 punches showing remarkable resilience
00:04:18 --> 00:04:20 however we shouldn't underestimate the
00:04:20 --> 00:04:22 immediate Devastation these impacts
00:04:22 --> 00:04:24 would have caused in the short term
00:04:24 --> 00:04:26 think decades to centuries these
00:04:26 --> 00:04:28 collisions would have created massive
00:04:28 --> 00:04:29 shock waves triggered enor ormous
00:04:30 --> 00:04:33 tsunamis and ignited widespread fires
00:04:33 --> 00:04:34 the impacts would have thrown massive
00:04:34 --> 00:04:36 amounts of dust into the atmosphere
00:04:36 --> 00:04:38 temporarily blocking out sunlight and
00:04:38 --> 00:04:41 disrupting life across the planet This
00:04:41 --> 00:04:43 research gives us valuable insights into
00:04:43 --> 00:04:45 Earth's ability to recover from major
00:04:45 --> 00:04:48 astronomical events while also serving
00:04:48 --> 00:04:50 as a reminder of the importance of
00:04:50 --> 00:04:52 modern-day asteroid detection and
00:04:52 --> 00:04:55 planetary defense programs after all
00:04:55 --> 00:04:57 while our planet may be resilient in the
00:04:57 --> 00:04:59 long term the immediate consequences of
00:04:59 --> 00:05:01 such impacts would be catastrophic for
00:05:01 --> 00:05:02 human
00:05:02 --> 00:05:05 civilization next up today exciting
00:05:05 --> 00:05:07 developments are emerging in the field
00:05:07 --> 00:05:08 of Space Telescope maintenance
00:05:09 --> 00:05:11 particularly for observatories stationed
00:05:11 --> 00:05:14 at the sunar lrange point L2 about a
00:05:14 --> 00:05:16 million miles from Earth scientists have
00:05:16 --> 00:05:18 designed a novel approach to extend the
00:05:18 --> 00:05:20 operational life of these invaluable
00:05:20 --> 00:05:23 instruments potentially saving billions
00:05:23 --> 00:05:26 in replacement costs the James web Space
00:05:26 --> 00:05:28 Telescope and Gaia two of our most
00:05:28 --> 00:05:30 powerful eyes in space are facing
00:05:30 --> 00:05:32 challenges that could limit their
00:05:32 --> 00:05:34 lifespans while web has already suffered
00:05:35 --> 00:05:36 some micr meteorite damage to its
00:05:37 --> 00:05:39 mirrors Gaia is running low on fuel
00:05:39 --> 00:05:42 after a decade of faithful service but
00:05:42 --> 00:05:44 researchers aren't ready to let these
00:05:44 --> 00:05:46 astronomical powerhouses fade away just
00:05:46 --> 00:05:49 yet a particularly Innovative solution
00:05:49 --> 00:05:51 involves a spider-like attachment
00:05:51 --> 00:05:53 designed to service these telescopes
00:05:53 --> 00:05:55 without disrupting their delicate
00:05:55 --> 00:05:57 operations this concept could be
00:05:57 --> 00:05:59 especially crucial for web which still
00:05:59 --> 00:06:00 has has many years of potential
00:06:00 --> 00:06:03 observations ahead the challenge lies
00:06:03 --> 00:06:05 not just in reaching these distant
00:06:05 --> 00:06:07 observatories but in servicing them
00:06:07 --> 00:06:10 without causing damage one of the
00:06:10 --> 00:06:11 trickiest aspects of this maintenance
00:06:12 --> 00:06:14 mission is the approach phase
00:06:14 --> 00:06:15 traditional breaking methods using
00:06:15 --> 00:06:18 thrusters could be catastrophic imagine
00:06:18 --> 00:06:19 pointing what amounts to a blowtorch at
00:06:19 --> 00:06:22 these sensitive instruments to address
00:06:22 --> 00:06:23 this researchers have developed new
00:06:23 --> 00:06:25 trajectory techniques that combine
00:06:25 --> 00:06:27 dynamical systems theory with optimal
00:06:27 --> 00:06:30 control theory creating effic
00:06:30 --> 00:06:32 and safe paths to reach these distant
00:06:32 --> 00:06:34 telescopes the research team has already
00:06:34 --> 00:06:37 completed plans for refueling Gaia while
00:06:37 --> 00:06:39 additional engineering work continues
00:06:39 --> 00:06:41 for web servicing missions these
00:06:41 --> 00:06:43 developments represent a significant
00:06:43 --> 00:06:44 shift in how we think about Space
00:06:44 --> 00:06:47 Telescope longevity moving from
00:06:47 --> 00:06:48 disposable instruments to serviceable
00:06:48 --> 00:06:50 ones that could potentially operate for
00:06:50 --> 00:06:52 decades with proper
00:06:52 --> 00:06:55 maintenance Europe's Vega sea rocket is
00:06:55 --> 00:06:57 poised to make its highly anticipated
00:06:57 --> 00:06:59 return to service marking a crucial
00:06:59 --> 00:07:01 moment for European space Independence
00:07:01 --> 00:07:03 the 35 met rocket has been fully
00:07:03 --> 00:07:06 assembled at Europe's Spaceport with its
00:07:06 --> 00:07:09 payload The Sentinel 1C satellite now
00:07:09 --> 00:07:12 securely mounted at the top of the stack
00:07:12 --> 00:07:14 as esa's compact launcher specialized in
00:07:14 --> 00:07:17 delivering payloads to Polar orbits Vega
00:07:17 --> 00:07:19 C Works alongside the recently debuted
00:07:19 --> 00:07:21 ariani 6 to ensure Europe maintains its
00:07:22 --> 00:07:24 Sovereign access to space this upcoming
00:07:24 --> 00:07:26 mission is particularly significant as
00:07:26 --> 00:07:28 it represents Vegas se's return after a
00:07:28 --> 00:07:31 2-year Hiatus and will be the 25th
00:07:31 --> 00:07:33 Flight of the Vega rocket family the
00:07:33 --> 00:07:35 Rockets assembly is a Marvel of
00:07:35 --> 00:07:37 engineering efficiency featuring four
00:07:37 --> 00:07:41 distinct stages at its base the p120c
00:07:41 --> 00:07:43 first stage stands as one of the world's
00:07:43 --> 00:07:46 most powerful single piece solid fuel
00:07:46 --> 00:07:48 Rocket Motors this component is shared
00:07:48 --> 00:07:51 with arani 6's boosters creating a
00:07:51 --> 00:07:53 cost-effective Synergy between the two
00:07:53 --> 00:07:55 launch systems the second stage the
00:07:55 --> 00:07:57 zafiro 40 comes equipped with an
00:07:57 --> 00:08:00 improved nozzle design and has undergone
00:08:00 --> 00:08:02 extensive testing to ensure
00:08:02 --> 00:08:05 reliability when launch day arrives the
00:08:05 --> 00:08:06 first three stages will Propel the
00:08:06 --> 00:08:08 rocket Skyward in a carefully
00:08:08 --> 00:08:10 choreographed sequence lasting just 8
00:08:10 --> 00:08:14 minutes the final stage known as avom
00:08:14 --> 00:08:16 plus will then take over performing a
00:08:16 --> 00:08:18 series of precise orbital Maneuvers
00:08:18 --> 00:08:20 before delivering Sentinel 1C to its
00:08:21 --> 00:08:24 designated orbit approximately 1 hour
00:08:24 --> 00:08:27 and 50 minutes after liftoff this return
00:08:27 --> 00:08:28 to flight represents more than just
00:08:29 --> 00:08:31 another launch it's a testament to
00:08:31 --> 00:08:33 European space capability and
00:08:33 --> 00:08:36 determination with both Vega C and arani
00:08:36 --> 00:08:39 6 operational Europe strengthens its
00:08:39 --> 00:08:40 position in the global space launch
00:08:40 --> 00:08:42 market while ensuring continued
00:08:42 --> 00:08:44 independent access to space for
00:08:44 --> 00:08:47 scientific missions and satellite
00:08:47 --> 00:08:49 deployment let's get an update from the
00:08:49 --> 00:08:53 jwst now the James web Space Telescope
00:08:53 --> 00:08:54 has once again demonstrated its
00:08:54 --> 00:08:57 extraordinary capabilities This Time by
00:08:57 --> 00:08:59 peering into the cosmic webike structure
00:08:59 --> 00:09:02 known as the spiderweb protocluster
00:09:02 --> 00:09:04 located an astounding 10 billion light
00:09:04 --> 00:09:07 years from Earth this massive Gathering
00:09:07 --> 00:09:09 of galaxies offers us a glimpse into the
00:09:09 --> 00:09:12 universe as it appeared Just 4 billion
00:09:12 --> 00:09:15 years after the big bang what makes this
00:09:15 --> 00:09:17 observation particularly exciting is
00:09:17 --> 00:09:19 that the web telescope has revealed
00:09:19 --> 00:09:22 previously hidden details of this Cosmic
00:09:22 --> 00:09:23 Metropolis in
00:09:23 --> 00:09:25 construction while earlier studies had
00:09:26 --> 00:09:28 identified around 100 galaxies in this
00:09:28 --> 00:09:31 region web infrared vision has uncovered
00:09:31 --> 00:09:33 even more galaxies that were completely
00:09:33 --> 00:09:36 obscured by Cosmic dust and gas the
00:09:36 --> 00:09:38 telescope's ability to penetrate through
00:09:38 --> 00:09:40 these Cosmic veils has provided
00:09:40 --> 00:09:43 astronomers with unprecedented views of
00:09:43 --> 00:09:45 hydrogen gas distribution and Galaxy
00:09:45 --> 00:09:46 formation
00:09:46 --> 00:09:49 processes surprisingly the research team
00:09:49 --> 00:09:51 found that many of the previously known
00:09:51 --> 00:09:53 galaxies weren't as dust filled as
00:09:53 --> 00:09:55 initially thought challenging our
00:09:55 --> 00:09:56 understanding of how these early Cosmic
00:09:56 --> 00:09:59 structures evolved one of the most
00:09:59 --> 00:10:01 remarkable aspects of this discovery is
00:10:01 --> 00:10:03 that these impressive results were
00:10:04 --> 00:10:05 achieved in just 3 and 1 half hours of
00:10:05 --> 00:10:08 observation time the findings suggest
00:10:08 --> 00:10:10 that the growth of these early galaxies
00:10:11 --> 00:10:12 might not have been primarily driven by
00:10:12 --> 00:10:15 dramatic events like Galaxy mergers or
00:10:15 --> 00:10:17 interactions but rather through a more
00:10:17 --> 00:10:20 gradual accumulation of gas across the
00:10:20 --> 00:10:22 structure this massive Cosmic City
00:10:22 --> 00:10:24 serves as a crucial laboratory for
00:10:24 --> 00:10:26 understanding how the largest structures
00:10:26 --> 00:10:29 in our universe came to be by studying
00:10:29 --> 00:10:31 these adolescent galaxies in the process
00:10:31 --> 00:10:33 of forming one of the universe's largest
00:10:33 --> 00:10:35 structures astronomers can better
00:10:35 --> 00:10:37 understand how the mature Galaxy
00:10:37 --> 00:10:39 clusters we see in the local Universe
00:10:39 --> 00:10:41 evolved over billions of
00:10:41 --> 00:10:44 years as you may have noticed our sun
00:10:44 --> 00:10:46 has been flexing its muscles lately and
00:10:46 --> 00:10:48 the consequences are being felt in
00:10:48 --> 00:10:51 Earth's orbit in early November three
00:10:51 --> 00:10:53 Australian satellites from curtain
00:10:53 --> 00:10:55 University's binar Space Program met an
00:10:55 --> 00:10:58 unexpectedly early demise burning up in
00:10:58 --> 00:11:00 Earth's at osphere just 2 months into
00:11:00 --> 00:11:02 their mission Far short of their planned
00:11:02 --> 00:11:03 6-month
00:11:03 --> 00:11:06 lifespan this premature end wasn't just
00:11:06 --> 00:11:08 bad luck it's a direct result of our sun
00:11:08 --> 00:11:11 entering an extraordinarily active phase
00:11:11 --> 00:11:13 causing Earth's upper atmosphere to
00:11:13 --> 00:11:15 expand and create increased drag on
00:11:15 --> 00:11:18 satellites in low earth orbit the binar
00:11:18 --> 00:11:20 satellites whose name fittingly means
00:11:20 --> 00:11:23 Fireball in the Nar language aren't the
00:11:23 --> 00:11:25 only victims of this enhanced solar
00:11:25 --> 00:11:28 activity satellite operators worldwide
00:11:28 --> 00:11:30 are grappling with similar challenges as
00:11:30 --> 00:11:32 solar activity surges to levels more
00:11:32 --> 00:11:35 than 1 and a half times higher than
00:11:35 --> 00:11:37 predicted for this point in the current
00:11:37 --> 00:11:38 solar
00:11:38 --> 00:11:40 cycle the effects of this increased
00:11:40 --> 00:11:43 solar activity are visible even from
00:11:43 --> 00:11:45 Earth with auroras appearing more
00:11:45 --> 00:11:47 frequently and closer to the Equator
00:11:47 --> 00:11:50 than we've seen in the past two decades
00:11:50 --> 00:11:52 but the real drama is playing out in
00:11:52 --> 00:11:55 space where satellites face multiple
00:11:55 --> 00:11:58 challenges beyond the atmospheric drag
00:11:58 --> 00:12:00 issue the heightened solar activity
00:12:00 --> 00:12:02 bombards Satellites with charged
00:12:02 --> 00:12:04 particles that can damage their
00:12:04 --> 00:12:06 electrical components and disrupt their
00:12:06 --> 00:12:09 operations while larger satellites like
00:12:09 --> 00:12:10 the International Space Station and
00:12:10 --> 00:12:13 starlink constellation can use thrusters
00:12:13 --> 00:12:15 to maintain their orbits smaller
00:12:15 --> 00:12:17 satellites like the binar cube sats are
00:12:17 --> 00:12:19 completely at the mercy of these solar
00:12:19 --> 00:12:22 effects this situation particularly
00:12:22 --> 00:12:24 impacts University and research
00:12:24 --> 00:12:26 satellites which often lack the
00:12:26 --> 00:12:28 sophisticated propulsion systems of
00:12:28 --> 00:12:31 their larger counter Parts looking ahead
00:12:31 --> 00:12:33 space weather forecasters predict this
00:12:33 --> 00:12:35 intense solar activity will likely
00:12:35 --> 00:12:38 continue until 2026 with solar minimum
00:12:38 --> 00:12:40 not expected until
00:12:40 --> 00:12:42 2030 this presents a significant
00:12:42 --> 00:12:45 challenge for satellite operators and
00:12:45 --> 00:12:46 underscores the growing importance of
00:12:46 --> 00:12:49 accurate space weather forecasting in
00:12:49 --> 00:12:52 our increasingly space dependent
00:12:52 --> 00:12:54 world and that's a wrap for today's
