00:00:40 --> 00:00:42 let's Journey Through the cosmos
00:00:42 --> 00:00:44 together let's Dive Right into our first
00:00:44 --> 00:00:47 story spacex's polaron Mission which has
00:00:47 --> 00:00:49 experienced yet another delay spacex's
00:00:49 --> 00:00:51 ambitious polaron astronaut mission was
00:00:52 --> 00:00:54 originally set to launch in late August
00:00:54 --> 00:00:55 from NASA's Kennedy Space Center in
00:00:55 --> 00:00:57 Florida however it has faced multiple
00:00:58 --> 00:01:00 delays the most recent due to unfavor
00:01:00 --> 00:01:02 able weather forecasts and a helium leak
00:01:02 --> 00:01:04 on Monday August 26th pre-flight
00:01:05 --> 00:01:06 checkouts revealed the need for further
00:01:06 --> 00:01:08 postponements a subsequent attempt was
00:01:08 --> 00:01:11 made on Tuesday August 27th but this was
00:01:11 --> 00:01:14 thwarted by a helium leak detected just
00:01:14 --> 00:01:16 before the launch to add to the hurdles
00:01:16 --> 00:01:18 unfavorable weather conditions off the
00:01:18 --> 00:01:20 coast of Florida prompted the team to
00:01:20 --> 00:01:21 stand down from both the Tuesday and
00:01:21 --> 00:01:24 Wednesday launch Windows as of now the
00:01:24 --> 00:01:26 earliest possible liftoff could be
00:01:26 --> 00:01:29 Friday August 30th as of now SpaceX has
00:01:29 --> 00:01:31 not not announced a new Target launch
00:01:31 --> 00:01:33 date but the team remains hopeful and is
00:01:33 --> 00:01:35 diligently monitoring both Technical and
00:01:35 --> 00:01:37 weather conditions to ensure a safe and
00:01:37 --> 00:01:40 successful Mission stay tuned for more
00:01:40 --> 00:01:42 updates as we follow the progress of
00:01:42 --> 00:01:44 this groundbreaking Mission let's dive
00:01:44 --> 00:01:46 into the fascinating world of Venus
00:01:46 --> 00:01:49 recently scientists have observed an
00:01:49 --> 00:01:51 unexpected increase in the level of dyum
00:01:51 --> 00:01:53 relative to hydrogen in Venus's
00:01:53 --> 00:01:55 atmosphere while this might sound like a
00:01:55 --> 00:01:57 minor detail the potential consequences
00:01:57 --> 00:01:59 are Monumental and could significantly
00:01:59 --> 00:02:01 alter understanding of this mysterious
00:02:01 --> 00:02:03 planet to understand the importance of
00:02:03 --> 00:02:05 this discovery we first need to explore
00:02:05 --> 00:02:08 what dyum and hydrogen actually are both
00:02:08 --> 00:02:11 are isotopes of the same element which
00:02:11 --> 00:02:12 means they have the same number of
00:02:12 --> 00:02:15 protons but differ in their number of
00:02:15 --> 00:02:17 neutrons this difference in atomic mass
00:02:17 --> 00:02:19 can lead to variations in their behavior
00:02:19 --> 00:02:22 particularly in atmospheric processes
00:02:22 --> 00:02:23 historically Venus and Earth were
00:02:23 --> 00:02:26 believed to share similar HDO or heavy
00:02:26 --> 00:02:29 water and H2O ratios since both planets
00:02:29 --> 00:02:30 formed in the same hot region of the
00:02:30 --> 00:02:32 early solar system where water couldn't
00:02:33 --> 00:02:35 condense it's thought that water along
00:02:35 --> 00:02:37 with other volatile elements like carbon
00:02:37 --> 00:02:39 and nitrogen was delivered to these
00:02:39 --> 00:02:41 worlds by water-rich asteroids this
00:02:41 --> 00:02:43 should have resulted in similar dyum to
00:02:43 --> 00:02:47 hydrogen DH ratios on both planets
00:02:47 --> 00:02:49 however new data throws this assumption
00:02:49 --> 00:02:51 into question by pouring over data from
00:02:51 --> 00:02:54 the solar occultation in the infrared s
00:02:54 --> 00:02:56 soir instrument on the Venus Express
00:02:56 --> 00:03:00 space probe operational from 2006 to
00:03:00 --> 00:03:03 2014 scientists found that the HDO ratio
00:03:03 --> 00:03:07 is now 120 Times Higher compared to H2O
00:03:07 --> 00:03:09 in Venus's atmosphere this change is
00:03:09 --> 00:03:11 primarily due to solar radiation
00:03:11 --> 00:03:13 breaking down water isotopologs in the
00:03:13 --> 00:03:15 upper atmosphere producing hydrogen and
00:03:15 --> 00:03:18 dyum atoms since hydrogen atoms Escape
00:03:18 --> 00:03:19 into space more easily due to their
00:03:19 --> 00:03:22 lower Mass the DH ratio in Venus's
00:03:22 --> 00:03:24 atmosphere has been gradually increasing
00:03:24 --> 00:03:26 more intriguingly the concentration of
00:03:26 --> 00:03:28 water molecules increases with altitude
00:03:28 --> 00:03:31 between 70 and 100 10 km above Venus's
00:03:31 --> 00:03:33 surface at these altitudes the ratio of
00:03:34 --> 00:03:37 HDO to H2O becomes staggeringly elevated
00:03:37 --> 00:03:39 around 1 times higher than in
00:03:39 --> 00:03:41 Earth's oceans this indicates that
00:03:41 --> 00:03:43 Venus's atmosphere contains much more
00:03:43 --> 00:03:46 dyum Rich water compared to Earth
00:03:46 --> 00:03:48 alluding to significant differences in
00:03:48 --> 00:03:50 the atmospheric processes of the two
00:03:50 --> 00:03:52 planets so there you have it another
00:03:53 --> 00:03:54 intriguing mystery in our solar system
00:03:54 --> 00:03:57 brought to light these findings open the
00:03:57 --> 00:03:59 door for numerous questions and further
00:03:59 --> 00:04:01 studies making Venus an even more
00:04:01 --> 00:04:03 captivating subject of astronomical
00:04:03 --> 00:04:05 research NASA's double asteroid
00:04:05 --> 00:04:07 redirection test or Dart Mission has
00:04:07 --> 00:04:09 provided some groundbreaking insights
00:04:09 --> 00:04:11 into asteroid Dynamics and planetary
00:04:11 --> 00:04:13 defense the mission made headlines when
00:04:13 --> 00:04:15 it intentionally collided with the
00:04:15 --> 00:04:17 asteroid Moon demoro and researchers are
00:04:17 --> 00:04:19 now revealing that this impact didn't
00:04:19 --> 00:04:22 just alter the moon's trajectory it also
00:04:22 --> 00:04:24 significantly changed its shape these
00:04:24 --> 00:04:26 changes are more complex than previously
00:04:26 --> 00:04:27 thought and could have far-reaching
00:04:27 --> 00:04:29 implications for our understanding of
00:04:29 --> 00:04:32 asteroid Evolution originally scientists
00:04:32 --> 00:04:34 had predicted how Dart would affect the
00:04:34 --> 00:04:36 dios demorphis system but the real world
00:04:36 --> 00:04:38 outcomes were even more dramatic than
00:04:38 --> 00:04:40 expected the Collision not only created
00:04:40 --> 00:04:42 a massive crater but also reshaped
00:04:42 --> 00:04:44 dioros from an oblate hamburger-like
00:04:44 --> 00:04:47 form into a more elongated football-like
00:04:47 --> 00:04:49 shape this shift altered the moon's
00:04:49 --> 00:04:50 gravitational relationship with its
00:04:50 --> 00:04:53 parent asteroid dios surprisingly dios
00:04:54 --> 00:04:56 itself remained relatively unchanged
00:04:56 --> 00:04:58 highlighting its firmness and rigidity
00:04:58 --> 00:04:59 despite the debris scattered by the
00:04:59 --> 00:05:02 impact Derek Richardson a professor of
00:05:02 --> 00:05:04 astronomy at the University of Maryland
00:05:04 --> 00:05:07 and a lead researcher on the project
00:05:07 --> 00:05:08 noted that the results challenge our
00:05:08 --> 00:05:10 conventional ideas about how small
00:05:10 --> 00:05:13 celestial bodies form and evolve
00:05:13 --> 00:05:14 traditionally it was believed that such
00:05:14 --> 00:05:16 moons would naturally Point their
00:05:16 --> 00:05:18 elongated axis towards the primary body
00:05:18 --> 00:05:21 due to gravitational influences however
00:05:21 --> 00:05:23 the PO impact changes inoros suggest a
00:05:23 --> 00:05:26 more intricate gravitational interaction
00:05:26 --> 00:05:27 interestingly the gravitational
00:05:27 --> 00:05:30 disruption between deorosan
00:05:30 --> 00:05:32 has led to some unusual orbital
00:05:32 --> 00:05:34 behaviors the debris generated by the
00:05:34 --> 00:05:36 Collision shortened dioros orbit around
00:05:36 --> 00:05:39 dios and the moon might now be in a
00:05:39 --> 00:05:41 state of chaotic tumbling akin to our
00:05:41 --> 00:05:43 moon always having one face towards the
00:05:43 --> 00:05:46 Earth but now knocked out of alignment
00:05:46 --> 00:05:47 this tumbling could continue for a
00:05:47 --> 00:05:49 significant period as the system
00:05:49 --> 00:05:51 attempts to regain gravitational
00:05:51 --> 00:05:53 equilibrium looking ahead Richardson and
00:05:53 --> 00:05:54 his team are eager to see how this
00:05:54 --> 00:05:56 altered state affects future space
00:05:56 --> 00:05:58 missions the upcoming European space
00:05:58 --> 00:06:00 agency's Hera mission will provide a
00:06:00 --> 00:06:02 closer examination of the binary
00:06:02 --> 00:06:05 asteroid system by late 2026 Hera aims
00:06:05 --> 00:06:07 to assess the internal properties of
00:06:07 --> 00:06:09 both dioros and dios providing vital
00:06:09 --> 00:06:11 data that could refine our planetary
00:06:11 --> 00:06:13 defense strategies this is particularly
00:06:13 --> 00:06:15 important because dart's findings are
00:06:15 --> 00:06:18 invaluable for real world applications
00:06:18 --> 00:06:20 by understanding how an artificial
00:06:20 --> 00:06:22 impact changes an asteroid's physical
00:06:22 --> 00:06:24 properties and trajectory we can better
00:06:24 --> 00:06:26 prepare for the possibility of diverting
00:06:26 --> 00:06:28 potentially hazardous asteroids away
00:06:28 --> 00:06:30 from Earth our lab experiments and
00:06:30 --> 00:06:32 computer simulations can't replicate
00:06:32 --> 00:06:34 these complex gravitational Dynamics as
00:06:34 --> 00:06:37 precisely making missions like Dart
00:06:37 --> 00:06:39 essential for Gathering real world data
00:06:39 --> 00:06:41 the hope is that these insights will
00:06:41 --> 00:06:43 contribute to methods of asteroid
00:06:43 --> 00:06:45 deflection that are both effective and
00:06:45 --> 00:06:47 efficient Richardson emphasizes that
00:06:47 --> 00:06:49 while the chances of a threatening
00:06:49 --> 00:06:51 asteroid or Comet hitting Earth are low
00:06:51 --> 00:06:53 they are not zero with the successive
00:06:53 --> 00:06:56 Dart Humanity now has an additional tool
00:06:56 --> 00:06:58 in its Arsenal for planetary defense
00:06:58 --> 00:07:00 offering a measure of protection against
00:07:00 --> 00:07:03 potential Cosmic threats as scientists
00:07:03 --> 00:07:06 continue to Monitor dioros and the dios
00:07:06 --> 00:07:08 system one of the burning questions is
00:07:08 --> 00:07:10 whether the moon will eventually
00:07:10 --> 00:07:12 stabilize enough for future exploratory
00:07:12 --> 00:07:14 missions including possibly Landing
00:07:14 --> 00:07:17 spacecraft to gather more detailed data
00:07:17 --> 00:07:20 in essence NASA's Dart Mission has not
00:07:20 --> 00:07:21 only furthered our understanding of
00:07:21 --> 00:07:24 asteroid Behavior but also paved the way
00:07:24 --> 00:07:26 for future space exploration and defense
00:07:26 --> 00:07:28 Technologies the revelations about
00:07:28 --> 00:07:30 demorphis altered State promised to keep
00:07:30 --> 00:07:32 the scientific Community buzzing with
00:07:32 --> 00:07:35 excitement and anticipation for years to
00:07:35 --> 00:07:37 come and now let's look at a new
00:07:37 --> 00:07:39 discovery from the Hubble nestled
00:07:39 --> 00:07:41 against a backdrop of distant celestial
00:07:41 --> 00:07:43 bodies a glittering collection of stars
00:07:43 --> 00:07:45 has been captured by NASA's Hubble Space
00:07:45 --> 00:07:47 Telescope this wondrous site forms the
00:07:47 --> 00:07:50 Pegasus dwarf spheroidal Galaxy also
00:07:50 --> 00:07:52 known as Andromeda 6 it's a modest
00:07:52 --> 00:07:54 member of a vast Cosmic Family yet it
00:07:54 --> 00:07:56 offers Monumental insights into the
00:07:56 --> 00:07:58 universe's Grand narrative situated
00:07:58 --> 00:08:00 within our local group of galaxies the
00:08:00 --> 00:08:02 Pegasus dwarf spheroidal Galaxy is one
00:08:02 --> 00:08:05 of at least 13 dwarf companions orbiting
00:08:05 --> 00:08:07 the well-known Andromeda galaxy also
00:08:08 --> 00:08:10 called Messier 31 in the grand scheme of
00:08:10 --> 00:08:12 things these dwarf galaxies are the
00:08:12 --> 00:08:14 dimmest and least massive yet their
00:08:14 --> 00:08:16 elliptical shapes and smooth star
00:08:16 --> 00:08:19 distributions hide a Galaxy formation
00:08:19 --> 00:08:21 taale that captivates astronomers
00:08:21 --> 00:08:24 discovered in 1998 Pegasus dwarf holds
00:08:24 --> 00:08:25 particular significance due to its
00:08:25 --> 00:08:28 unique composition unlike many other
00:08:28 --> 00:08:30 galaxies in its category
00:08:30 --> 00:08:31 it has a slightly higher content of
00:08:31 --> 00:08:34 heavy elements and a smidgen of gas that
00:08:34 --> 00:08:36 has against the odds supported minor
00:08:36 --> 00:08:39 star formation however this sparse raw
00:08:40 --> 00:08:41 material is still insufficient for
00:08:41 --> 00:08:44 creating new generations of stars making
00:08:44 --> 00:08:46 researchers attribute the lack of it to
00:08:46 --> 00:08:48 the gravitational impact of its massive
00:08:48 --> 00:08:51 neighbor Andromeda over time Andromeda
00:08:51 --> 00:08:52 is thought to have drained Pegasus dwarf
00:08:52 --> 00:08:55 of its staring gases much like a cosmic
00:08:55 --> 00:08:57 giant siphoning life from its petite
00:08:57 --> 00:08:59 companion what intrigued science
00:08:59 --> 00:09:01 scientist is how these dwarf spheroidal
00:09:01 --> 00:09:03 galaxies including Pegasus dwarf come
00:09:03 --> 00:09:05 into being several theories are on the
00:09:05 --> 00:09:07 cosmic drawing board some suggest these
00:09:07 --> 00:09:09 mini galaxies might form from fragments
00:09:09 --> 00:09:12 broken off larger Galactic collisions
00:09:12 --> 00:09:13 While others proposed that the
00:09:13 --> 00:09:15 gravitational forces exerted by Massive
00:09:15 --> 00:09:17 galaxies like Andromeda shape these
00:09:17 --> 00:09:20 small systems another hypothesis
00:09:20 --> 00:09:22 highlights the role of Dark Matter a
00:09:22 --> 00:09:24 mysterious substance thought to make up
00:09:24 --> 00:09:27 a large portion of the universe's Mass
00:09:27 --> 00:09:29 it's believed that Pegasus dwarf and its
00:09:29 --> 00:09:31 ill could shrink into existence among
00:09:31 --> 00:09:34 clusters of this elusive Dark Matter
00:09:34 --> 00:09:36 warping space and time to create such
00:09:36 --> 00:09:38 fascinating formations the light we see
00:09:38 --> 00:09:40 from the stars in Pegasus dwarf speaks
00:09:40 --> 00:09:43 to us from a Time long gone the Galaxy
00:09:43 --> 00:09:45 Star population is predominantly older
00:09:45 --> 00:09:47 having spent their lives in the low
00:09:47 --> 00:09:49 density gasp environment of the dwarf

00:09:55 --> 00:09:57 piecing together the life history of
00:09:57 --> 00:09:59 such galaxies and their roles in the
00:09:59 --> 00:10:01 larger Galactic
00:10:01 --> 00:10:03 ecosystem as we reported last week on
00:10:03 --> 00:10:06 September 8th 2024 an exciting event is
00:10:06 --> 00:10:08 set to unfold as the salsa satellite
00:10:08 --> 00:10:10 re-enters Earth's atmosphere this isn't
00:10:10 --> 00:10:11 just any re-entry it's a notable
00:10:11 --> 00:10:13 milestone in space exploration and
00:10:13 --> 00:10:16 satellite technology salsa is one of the
00:10:16 --> 00:10:17 four satellites from the European space
00:10:17 --> 00:10:20 agency's EA long running cluster Mission
00:10:20 --> 00:10:22 what makes this re-entry special is that
00:10:22 --> 00:10:24 it will be observed live from the sky
00:10:24 --> 00:10:26 scientists have prepared an Airborne
00:10:26 --> 00:10:28 observation experiment to closely watch
00:10:28 --> 00:10:29 and gather rare data data on how the
00:10:29 --> 00:10:32 satellite breaks apart upon re-entry
00:10:32 --> 00:10:34 this data is invaluable because
00:10:34 --> 00:10:35 understanding the finer details of
00:10:35 --> 00:10:37 satellite disintegration can lead to
00:10:37 --> 00:10:39 designing satellites that re-enter more
00:10:39 --> 00:10:41 safely and sustainably in the future
00:10:41 --> 00:10:43 over the past s Decades of space
00:10:43 --> 00:10:45 exploration although approximately
00:10:45 --> 00:10:47 10 intact satellites and Rocket
00:10:48 --> 00:10:50 bodies have re-entered our atmosphere
00:10:50 --> 00:10:51 the specifics of what happens during
00:10:51 --> 00:10:54 these re-entries remain unclear this
00:10:54 --> 00:10:55 experiment with salsa aims to change
00:10:55 --> 00:10:58 that the head of space safety at Esa
00:10:58 --> 00:11:00 hoger Kow emphasized the importance of
00:11:00 --> 00:11:02 re-entry science in efforts to keep our
00:11:02 --> 00:11:05 orbits around earth clean he stated to
00:11:05 --> 00:11:07 remove a satellite quickly from orbit
00:11:07 --> 00:11:08 after its Mission ends and to prevent
00:11:08 --> 00:11:11 space debris understanding the re-entry
00:11:11 --> 00:11:13 process is essential the insights from
00:11:13 --> 00:11:15 Salsa's re-entry are expected to be
00:11:15 --> 00:11:17 groundbreaking helping us refine
00:11:17 --> 00:11:19 satellite design and operations to
00:11:19 --> 00:11:21 minimize space debris effectively the
00:11:21 --> 00:11:23 observation Mission involves an aircraft
00:11:23 --> 00:11:25 equipped with over 20 scientific
00:11:25 --> 00:11:27 instruments including cameras and
00:11:27 --> 00:11:29 spectrographs these struments are
00:11:29 --> 00:11:31 designed to capture as much data as
00:11:31 --> 00:11:32 possible when salsa re-enters the
00:11:32 --> 00:11:35 atmosphere interestingly the first of
00:11:35 --> 00:11:37 the cluster satellites to re-enter has
00:11:37 --> 00:11:38 been strategically scheduled to fall
00:11:38 --> 00:11:40 over a remote area in the South Pacific
00:11:40 --> 00:11:43 Ocean this region was chosen to minimize
00:11:43 --> 00:11:45 the risk to populated areas as most of
00:11:45 --> 00:11:47 the satellite will disintegrate within
00:11:47 --> 00:11:49 minutes of hitting the atmosphere
00:11:49 --> 00:11:52 although some fragments May survive the
00:11:52 --> 00:11:54 predictable nature of Salsa's re-entry
00:11:54 --> 00:11:57 time and location makes it possible for
00:11:57 --> 00:11:58 scientists to be in place with their
00:11:58 --> 00:12:00 observations equipment this
00:12:00 --> 00:12:02 predictability stems from the cluster
00:12:02 --> 00:12:04 satellites highly eccentric orbits which
00:12:05 --> 00:12:08 cause substantial altitude loss at pery
00:12:08 --> 00:12:09 the point closest to Earth in the
00:12:09 --> 00:12:11 satellites orbit the re-entry
00:12:11 --> 00:12:14 observation Mission dubbed Rosie salsa
00:12:14 --> 00:12:16 showcases a collaborative effort
00:12:16 --> 00:12:17 involving academic and Industrial
00:12:18 --> 00:12:20 Partners such as the University of
00:12:20 --> 00:12:22 stutgart commenius university in
00:12:22 --> 00:12:24 Bratislava University of Southern
00:12:24 --> 00:12:26 Queensland Hypersonic technology gotting
00:12:26 --> 00:12:28 in and Astro Solutions in close
00:12:28 --> 00:12:32 cooperation with Esa Jerry silha CEO of
00:12:32 --> 00:12:34 Astro Solutions highlighted the
00:12:34 --> 00:12:37 mission's challenges stating this is a
00:12:37 --> 00:12:39 very challenging Mission due to the
00:12:39 --> 00:12:42 unpredictable nature of re-entry events
00:12:42 --> 00:12:44 however with experts in both science and
00:12:44 --> 00:12:46 Technical preparation we are confident
00:12:46 --> 00:12:48 in securing all the relevant scientific
00:12:48 --> 00:12:51 data from Salsa's
