00:00:31 --> 00:00:38 [Music]
00:00:45 --> 00:00:48 Gary a new study has shown that the
00:00:48 --> 00:00:51 universe's first galaxies weren't overly
00:00:51 --> 00:00:53 massive after all but it appears their
00:00:53 --> 00:00:55 Central black holes were making them
00:00:55 --> 00:00:58 seem bigger and brighter the findings
00:00:58 --> 00:01:00 reported in the astronomical Journal
00:01:00 --> 00:01:02 shows that galaxies which appeared
00:01:02 --> 00:01:03 overly massive in the very early
00:01:03 --> 00:01:06 Universe most likely hosted black holes
00:01:06 --> 00:01:09 which were rapidly consuming gas making
00:01:09 --> 00:01:10 them both brighter in appearance and
00:01:10 --> 00:01:12 also look bigger than they really were
00:01:12 --> 00:01:15 as a result you see when astronomers got
00:01:15 --> 00:01:17 their first glimpses of galaxies in the
00:01:17 --> 00:01:19 early Universe from NASA's web Space
00:01:19 --> 00:01:21 Telescope they're expecting to find lots
00:01:21 --> 00:01:24 of Galactic dwarves but instead what
00:01:24 --> 00:01:27 they found appear to be a bevy of giants
00:01:27 --> 00:01:29 some galaxies appear to have grown so
00:01:29 --> 00:01:31 massive so quickly that simulation
00:01:31 --> 00:01:34 simply couldn't account for it and that
00:01:34 --> 00:01:36 suggested that something must be wrong
00:01:36 --> 00:01:37 with science's understanding of the
00:01:37 --> 00:01:39 standard model of cosmology that's the
00:01:39 --> 00:01:41 theory that explains what the universe
00:01:41 --> 00:01:44 was made of and how it evolved since the
00:01:44 --> 00:01:47 Big Bang 13.8 billion years ago a
00:01:47 --> 00:01:49 study's lead author Katherine chowski
00:01:49 --> 00:01:51 from the University of Texas at Austin
00:01:51 --> 00:01:53 says some of these early galaxies are in
00:01:53 --> 00:01:55 fact much less massive than they first
00:01:55 --> 00:01:57 appeared but their Central super massive
00:01:57 --> 00:02:00 black holes feeding verocious make them
00:02:00 --> 00:02:01 appear to be much brighter and bigger
00:02:01 --> 00:02:04 than they really are she says while
00:02:04 --> 00:02:05 astronomers are still seeing more
00:02:05 --> 00:02:07 galaxies than predicted none of them are
00:02:07 --> 00:02:09 so massive that they break the universe
00:02:09 --> 00:02:11 or at least science's understanding of
00:02:11 --> 00:02:14 it the evidence was provided by web's
00:02:14 --> 00:02:16 Cosmic Evolution early release science
00:02:16 --> 00:02:19 survey it was led by study co-author
00:02:19 --> 00:02:22 Steven finklestein also from UT Austin
00:02:22 --> 00:02:24 it shows that friction in the fast
00:02:24 --> 00:02:26 moving gas being consumed by these super
00:02:26 --> 00:02:28 massive black holes emits a lot of heat
00:02:28 --> 00:02:30 and light making the galaxies appear to
00:02:30 --> 00:02:32 be much brighter than they would be were
00:02:32 --> 00:02:35 the light emitted just from Stars so
00:02:35 --> 00:02:37 this extra light is what's making it
00:02:37 --> 00:02:39 appear that the galaxies contain more
00:02:39 --> 00:02:41 stars than they really do and hence are
00:02:41 --> 00:02:44 more massive when scientists remove
00:02:44 --> 00:02:46 these galaxies dub little red dots based
00:02:46 --> 00:02:48 on their red color and small size from
00:02:48 --> 00:02:50 their analysis the remaining early
00:02:50 --> 00:02:52 galaxies are no longer too massive to
00:02:52 --> 00:02:54 fit within the predictions of the
00:02:54 --> 00:02:57 standard model although they've settled
00:02:57 --> 00:02:59 the main dilemma a l Les thorny problem
00:02:59 --> 00:03:01 remains means you see there are still
00:03:01 --> 00:03:03 roughly twice as many massive galaxies
00:03:03 --> 00:03:05 in the web data of the early universe as
00:03:05 --> 00:03:07 what was expected according to the
00:03:07 --> 00:03:09 standard model now one possible
00:03:09 --> 00:03:11 explanation for this is that stars
00:03:11 --> 00:03:13 simply formed more quickly in the early
00:03:13 --> 00:03:16 Universe than what they do now chowski
00:03:16 --> 00:03:18 proposes the early Universe was simply
00:03:18 --> 00:03:21 better at turning gas into stars star
00:03:21 --> 00:03:24 formation happens when molecular gas and
00:03:24 --> 00:03:26 dust clouds cool enough for denser
00:03:26 --> 00:03:28 regions in those clouds to start to
00:03:28 --> 00:03:31 collapse under their own and gravity
00:03:31 --> 00:03:32 this eventually becomes a sort of
00:03:32 --> 00:03:35 runaway effect ultimately turning the
00:03:35 --> 00:03:38 gas into stars but as the gas contracts
00:03:38 --> 00:03:41 it heats up generating outward pressure
00:03:41 --> 00:03:43 now in our region of the universe this
00:03:43 --> 00:03:45 balance of the opposing forces tends to
00:03:45 --> 00:03:47 make the star formation process very
00:03:47 --> 00:03:50 slow the Milky Way for example is only
00:03:50 --> 00:03:52 producing one solar mass star every
00:03:52 --> 00:03:55 Earth year at the moment but perhaps
00:03:55 --> 00:03:57 because the early Universe was closer
00:03:57 --> 00:03:59 together and hence denser it would have
00:03:59 --> 00:04:01 been hard to blow gas out during star
00:04:01 --> 00:04:03 formation allowing the process to go
00:04:03 --> 00:04:06 faster concurrently astronomers have
00:04:06 --> 00:04:08 been analyzing the Spectre of little red
00:04:08 --> 00:04:10 dots discovered with web finding
00:04:10 --> 00:04:13 evidence of fast moving hydrogen gas a
00:04:13 --> 00:04:16 signature of black hole action discs and
00:04:16 --> 00:04:18 this supports the idea that at least
00:04:18 --> 00:04:19 some of the light coming from these
00:04:19 --> 00:04:21 compact red objects comes from gas
00:04:21 --> 00:04:23 swirling around black holes rather than
00:04:23 --> 00:04:27 Stars reinforcing our author's
00:04:27 --> 00:04:30 conclusions this is spacetime
00:04:30 --> 00:04:32 still to come NASA's Europa Clipper
00:04:32 --> 00:04:34 Mission moving closer towards its
00:04:34 --> 00:04:36 October launch date and SpaceX puts
00:04:36 --> 00:04:39 Falon 9 Launches on hold following a
00:04:39 --> 00:04:42 spectacular Landing failure all that and
00:04:42 --> 00:04:46 more still to come on SpaceTime
00:04:46 --> 00:05:00 [Music]
00:05:00 --> 00:05:02 NASA's Europa Clipper Mission the
00:05:02 --> 00:05:04 largest spacecraft NASA has ever built
00:05:04 --> 00:05:06 for interplanetary exploration is now on
00:05:06 --> 00:05:08 track for a launch window opening on
00:05:08 --> 00:05:12 October 10 the next major milestone for
00:05:12 --> 00:05:14 Clipper is key decision Point e that'll
00:05:14 --> 00:05:16 be on September the 9th when the agency
00:05:16 --> 00:05:18 will decide whether the Project's ready
00:05:18 --> 00:05:20 to proceed to launch and Mission
00:05:20 --> 00:05:22 operations the spacecraft's now been
00:05:22 --> 00:05:24 fitted with its enormous solar arrays at
00:05:24 --> 00:05:26 the agency's Kennedy Space Center in
00:05:26 --> 00:05:28 Florida each of the two massive solar
00:05:28 --> 00:05:32 arrays measures 14.2 M long and 4.1 M
00:05:32 --> 00:05:34 wide and just like the rest of the
00:05:34 --> 00:05:36 spacecraft they too are the biggest
00:05:36 --> 00:05:38 nases ever developed for an
00:05:38 --> 00:05:40 interplanetary Mission and of course
00:05:40 --> 00:05:43 they have to be so large so they can cir
00:05:43 --> 00:05:45 up as much sunlight as possible during
00:05:45 --> 00:05:46 the spacecrafts mission to study
00:05:46 --> 00:05:49 Jupiter's ice Moon Europa which is five
00:05:49 --> 00:05:51 times further away from the Sun than the
00:05:51 --> 00:05:53 Earth the Rays have now been folded up
00:05:53 --> 00:05:55 and secured against the spacecraft's
00:05:55 --> 00:05:57 main body for the launch but when
00:05:57 --> 00:05:59 they're deployed in space Europa clip
00:05:59 --> 00:06:02 will span more than 30.5 M across that's
00:06:02 --> 00:06:05 longer than a basketball court the wings
00:06:05 --> 00:06:07 as Engineers call them so big that they
00:06:07 --> 00:06:09 could only be opened one at a time in
00:06:09 --> 00:06:11 the clean room of the Kennedy Space
00:06:11 --> 00:06:13 Center's payload hazardous servicing
00:06:13 --> 00:06:15 facility where teams are readying the
00:06:15 --> 00:06:17 spacecraft for launch this report from
00:06:17 --> 00:06:20 NASA TV it's going to take 6 years to
00:06:20 --> 00:06:22 get out there just think about the size
00:06:22 --> 00:06:24 just blers the Sol is a Powerhouse for
00:06:24 --> 00:06:26 the spacecraft on its Journey from Earth
00:06:26 --> 00:06:28 to Europa we've just completed our first
00:06:28 --> 00:06:30 flight like to deployment these solar
00:06:30 --> 00:06:32 rays are so big we can only test One
00:06:32 --> 00:06:34 Wing at a time these solar rays are
00:06:34 --> 00:06:36 really unique in that not only do they
00:06:36 --> 00:06:37 need to survive extremely cold
00:06:37 --> 00:06:41 temperatures - 400° F it's also meant to
00:06:41 --> 00:06:43 survive the extremely harsh Jupiter
00:06:43 --> 00:06:44 radiation environment we've built the
00:06:44 --> 00:06:46 solar r on Earth we've tested them but
00:06:46 --> 00:06:49 now they're actually going to Jupiter to
00:06:49 --> 00:06:51 provide Power to all the instruments in
00:06:51 --> 00:06:53 the spacecraft to send back valuable
00:06:53 --> 00:06:55 science it's an engineering feat that
00:06:55 --> 00:06:57 we're able to develop this it is
00:06:57 --> 00:06:59 extremely exciting for me to be part of
00:06:59 --> 00:07:02 that's TJ Lee from John's Hopkins
00:07:02 --> 00:07:05 University each solar array is composed
00:07:05 --> 00:07:07 of five panels needed to power the
00:07:07 --> 00:07:09 flybys in a region of the solar system
00:07:09 --> 00:07:11 that only receives 3 to 4% of the
00:07:11 --> 00:07:14 sunlight the Earth getes designed and
00:07:14 --> 00:07:15 built at the John's Hopkins Applied
00:07:15 --> 00:07:18 Physics laboratory in lurel Maryland and
00:07:18 --> 00:07:20 Airbus in Leiden in the Netherlands
00:07:20 --> 00:07:21 these solar arrays are far more
00:07:21 --> 00:07:23 sensitive than the type of solar panels
00:07:23 --> 00:07:26 used on homes and the highly efficient
00:07:26 --> 00:07:28 euroba Clipper spacecraft will make the
00:07:28 --> 00:07:30 most out of the power they generate once
00:07:30 --> 00:07:33 in Jovian orbit Europa Clippers solar
00:07:33 --> 00:07:35 arrays will together provide roughly 700
00:07:35 --> 00:07:38 wats of power that's about what a small
00:07:38 --> 00:07:40 microwave oven or a kitchen coffee maker
00:07:40 --> 00:07:43 uses a board Clipper batteries will
00:07:43 --> 00:07:44 store the power to run all the
00:07:44 --> 00:07:46 electronics the full payload of science
00:07:46 --> 00:07:49 instruments Communications equipment the
00:07:49 --> 00:07:51 onboard computer and the entire
00:07:51 --> 00:07:53 propulsion system which includes 24
00:07:53 --> 00:07:55 engines and while powering all that the
00:07:55 --> 00:07:57 arrays also need to operate in extreme
00:07:58 --> 00:08:00 cold the space Craft's temperature will
00:08:00 --> 00:08:03 plunge to - 240° c when operating
00:08:03 --> 00:08:06 through Jupiter Shadow and to ensure the
00:08:06 --> 00:08:08 solar panels can operating those
00:08:08 --> 00:08:10 extremes Engineers tested them in a
00:08:10 --> 00:08:13 specialized cryogenic chamber in Belgium
00:08:13 --> 00:08:15 see the spacecraft itself has heaters
00:08:15 --> 00:08:17 and an internal thermal Loop which keeps
00:08:17 --> 00:08:19 the onboard systems in a fairly normal
00:08:19 --> 00:08:21 temperature range but the solar arrays
00:08:22 --> 00:08:24 are exposed to the vacuum of space
00:08:24 --> 00:08:26 without heaters they're completely
00:08:26 --> 00:08:28 passive so whatever the local
00:08:28 --> 00:08:30 environmental temperature is that's the
00:08:30 --> 00:08:32 temperature they get about 90 minutes
00:08:32 --> 00:08:34 after launch the solar arrays will
00:08:34 --> 00:08:36 unfill from their forth position over
00:08:36 --> 00:08:39 the course of about 40 minutes about 2
00:08:39 --> 00:08:43 weeks later 6 17.6 M antennas a fixed to
00:08:43 --> 00:08:45 the arrays will also deploy to their
00:08:45 --> 00:08:48 full size these antennas belong to the
00:08:48 --> 00:08:50 radar instrument and they'll search for
00:08:50 --> 00:08:51 water within and beneath the Jovian
00:08:52 --> 00:08:54 Moon's thick icy shell meanwhile
00:08:54 --> 00:08:56 Engineers have just completed tests on
00:08:56 --> 00:08:58 the radiation heiness of the transistors
00:08:58 --> 00:09:00 being used on the Europa clippa
00:09:00 --> 00:09:03 spacecraft longevity is key because the
00:09:03 --> 00:09:05 spacecraft will Journey for more than 5
00:09:05 --> 00:09:07 years in order to arrive at the Jian
00:09:07 --> 00:09:10 system in 2030 as it orbits the gas
00:09:10 --> 00:09:12 giant the probe will fly by Europa
00:09:12 --> 00:09:15 multiple times using a squid of science
00:09:15 --> 00:09:16 instruments to find out whether the
00:09:16 --> 00:09:18 liquid water ocean beneath the moon's
00:09:18 --> 00:09:21 Frozen surface has the right sort of
00:09:21 --> 00:09:24 conditions to support Life as We Know It
00:09:24 --> 00:09:25 Europa is slightly larger than the
00:09:26 --> 00:09:28 Earth's moon but contains more water
00:09:28 --> 00:09:31 than all the Earth's oceans combined
00:09:31 --> 00:09:33 many scientists believe that life on
00:09:33 --> 00:09:35 Earth began in the oceans possibly at
00:09:35 --> 00:09:38 mid ocean ridges where unique habitats
00:09:38 --> 00:09:41 exist those same sort of conditions are
00:09:41 --> 00:09:43 thought to exist on the floors of
00:09:43 --> 00:09:45 europa's oceans which raises the
00:09:45 --> 00:09:47 question could life have formed there as
00:09:47 --> 00:09:50 well and that question is fascinating
00:09:50 --> 00:09:52 because if we do eventually find life on
00:09:52 --> 00:09:55 say the red planet Mars well that would
00:09:55 --> 00:09:57 be exciting but Earth and Mars have been
00:09:57 --> 00:10:00 swapping rocks for billions of years is
00:10:00 --> 00:10:02 so there's always a possibility that a
00:10:02 --> 00:10:04 meteorite strike on Mars from Earth may
00:10:04 --> 00:10:06 have contaminated the red planet with
00:10:06 --> 00:10:09 Earthly microbes on the other hand it
00:10:09 --> 00:10:10 could have been Martian microbes which
00:10:10 --> 00:10:13 first provided the Earth with life in
00:10:13 --> 00:10:15 which case we're all really
00:10:15 --> 00:10:18 martians but if life is found out beyond
00:10:18 --> 00:10:20 the snow line on the Jovian Moon Europa
00:10:20 --> 00:10:22 that's a completely different story
00:10:22 --> 00:10:24 that's not a case of pan spermia
00:10:24 --> 00:10:27 contamination from somewhere else it
00:10:27 --> 00:10:28 would mean that life arose there
00:10:28 --> 00:10:31 independent ly and if life has arisen in
00:10:31 --> 00:10:33 our solar system at two separate
00:10:33 --> 00:10:36 locations it would mean life must be
00:10:36 --> 00:10:38 common throughout the
00:10:38 --> 00:10:40 Universe Europa Clipper's main science
00:10:40 --> 00:10:42 objectives are to determine the
00:10:42 --> 00:10:44 thickness of the moon's icy shell and
00:10:44 --> 00:10:46 its interactions with the ocean below to
00:10:46 --> 00:10:48 investigate its composition and to
00:10:48 --> 00:10:51 characterize its geology the mission's
00:10:51 --> 00:10:53 detailed exploration of Europa will help
00:10:53 --> 00:10:54 scientists better understand the
00:10:54 --> 00:10:56 astrobiological potential for habitable
00:10:56 --> 00:11:00 worlds beyond Earth the spacecraft was
00:11:00 --> 00:11:01 assembled at NASA's jet propulsion
00:11:01 --> 00:11:04 laboratory in Pasadena California it was
00:11:04 --> 00:11:06 then transported across the country to
00:11:06 --> 00:11:08 the cape canaval space for space in
00:11:08 --> 00:11:11 Florida an operation which as NASA TV
00:11:11 --> 00:11:14 explains has its own logistical problems
00:11:14 --> 00:11:16 have you ever thought about how we take
00:11:16 --> 00:11:18 a spacecraft from the jet propulsion
00:11:18 --> 00:11:20 laboratory in Pasadena California and
00:11:20 --> 00:11:23 move it to Florida to get launched the
00:11:23 --> 00:11:25 engineers the technicians the quality
00:11:25 --> 00:11:27 assurance members of our team are
00:11:27 --> 00:11:30 actually getting our spacecraft ready
00:11:30 --> 00:11:32 the process for preparing the spacecraft
00:11:32 --> 00:11:36 is really a art form a dance one of the
00:11:36 --> 00:11:38 things that we have to think about is
00:11:38 --> 00:11:40 how we're going to make our spacecraft
00:11:41 --> 00:11:43 fit inside of our Shi ring container we
00:11:43 --> 00:11:45 have to figure out what Hardware needs
00:11:45 --> 00:11:47 to ship with the main spacecraft and
00:11:47 --> 00:11:48 what Hardware needs to be taken off like
00:11:48 --> 00:11:51 taking off the High Gain antenna one of
00:11:51 --> 00:11:53 the things we need to do is lift a
00:11:53 --> 00:11:54 spacecraft from its ground support
00:11:54 --> 00:11:56 equipment and move it into the shipping
00:11:56 --> 00:11:58 container stop okay perfect our multi-
00:11:58 --> 00:12:00 mission container was specially designed
00:12:00 --> 00:12:04 to carry spacecraft across the country
00:12:04 --> 00:12:05 that means that the temperature is
00:12:05 --> 00:12:07 controlled the environment's controlled
00:12:07 --> 00:12:10 how many particles that can be inside
00:12:10 --> 00:12:11 are controlled to make sure that our
00:12:11 --> 00:12:13 spacecraft stays clean and
00:12:13 --> 00:12:16 safe the spacecraft has an amazing
00:12:16 --> 00:12:19 journey once we're in the shipping
00:12:19 --> 00:12:20 container got
00:12:21 --> 00:12:21 [Music]
00:12:21 --> 00:12:23 [Applause]
00:12:23 --> 00:12:25 him it goes from
00:12:25 --> 00:12:28 JPL on a big semi
00:12:28 --> 00:12:31 [Music]
00:12:31 --> 00:12:33 it ends up at March Air Reserve
00:12:33 --> 00:12:36 Base once it arrives at March we unload
00:12:36 --> 00:12:40 it and rapidly move it into a c17 for a
00:12:40 --> 00:12:42 flight that will take it to Kennedy
00:12:42 --> 00:12:48 Space
00:12:48 --> 00:12:50 Center so the spacecraft isn't the only
00:12:50 --> 00:12:52 thing that we actually pack up and ship
00:12:52 --> 00:12:54 across the country there's all these
00:12:54 --> 00:12:55 things that we call Ground support
00:12:55 --> 00:12:57 equipment gsse that need to go with us
00:12:57 --> 00:13:01 those help us manage the spacecraft we
00:13:01 --> 00:13:05 have 12 trucks of ground support
00:13:05 --> 00:13:07 equipment and then we will have two
00:13:07 --> 00:13:09 trucks that support the spacecraft move
00:13:09 --> 00:13:12 itself so a grand total of 14
00:13:12 --> 00:13:15 trucks emotionally this is one of the
00:13:15 --> 00:13:17 scariest periods of time it's the first
00:13:17 --> 00:13:20 time the spacecraft is going from a very
00:13:20 --> 00:13:22 very very controlled environment and
00:13:22 --> 00:13:23 going into more of an uncontrolled
00:13:23 --> 00:13:27 environment where other human beings are
00:13:27 --> 00:13:31 around the behind the scenes is a lot of
00:13:31 --> 00:13:34 Engineers that are planning out every
00:13:34 --> 00:13:35 step of this
00:13:35 --> 00:13:38 process lots of members of our assembly
00:13:38 --> 00:13:40 test and launch operations team actually
00:13:40 --> 00:13:42 uproot their families and moved to
00:13:42 --> 00:13:46 Florida for 6 months my emotions for
00:13:46 --> 00:13:47 Europa Clipper and the spacecraft
00:13:47 --> 00:13:49 leaving is Bittersweet I think it's
00:13:49 --> 00:13:50 going to feel like if my kids go off to
00:13:51 --> 00:13:52 college when the spacecraft was here in
00:13:52 --> 00:13:54 Southern California I could come over
00:13:54 --> 00:13:55 and visit anytime I wanted to now in
00:13:55 --> 00:13:57 Florida it's going to be a little bit
00:13:57 --> 00:13:59 more difficult it's more like getting a
00:13:59 --> 00:14:00 phone call every other week but it's
00:14:00 --> 00:14:03 going to be exciting too because now our
00:14:03 --> 00:14:05 spacecraft is getting ready to do its
00:14:05 --> 00:14:06 final dance it's getting ready to
00:14:06 --> 00:14:08 graduate and be on its way to do this
00:14:08 --> 00:14:10 science around Europa this beautiful
00:14:10 --> 00:14:14 moon around
00:14:14 --> 00:14:17 Jupiter and in that report from NASA TV
00:14:17 --> 00:14:18 we heard from Europa Clipper chief
00:14:18 --> 00:14:21 engineer kobby boyin and Europa Clipper
00:14:21 --> 00:14:24 integration engineer Ben Marty this is
00:14:24 --> 00:14:27 spacetime still to come SpaceX puts
00:14:27 --> 00:14:30 falcon9 Launches on hold following a
00:14:30 --> 00:14:32 spectacular Landing failure and later in
00:14:32 --> 00:14:34 the science report a new study shows
00:14:34 --> 00:14:36 that taking a break from screen time
00:14:36 --> 00:14:39 works wonders for kids mental health all
00:14:39 --> 00:14:44 that and more still to come on
00:14:44 --> 00:14:56 [Music]
00:14:56 --> 00:14:59 SpaceTime SpaceX placed the bridge brief
00:14:59 --> 00:15:01 Haul on Falcon 99 rocket launches last
00:15:01 --> 00:15:03 week after one of them caught fire blew
00:15:03 --> 00:15:05 up and then fell over as it was
00:15:05 --> 00:15:07 attempting to land on a droneship
00:15:07 --> 00:15:09 following what was a successful starc
00:15:09 --> 00:15:12 deployment mission to space right now
00:15:12 --> 00:15:14 SpaceX is still the only company Landing
00:15:14 --> 00:15:17 orbital class Rockets after use and
00:15:17 --> 00:15:19 they've become so good at it people
00:15:19 --> 00:15:21 forget just how revolutionary the feat
00:15:21 --> 00:15:24 really is so when one of them fails to
00:15:24 --> 00:15:27 survive the landing it raises eyebrows
00:15:27 --> 00:15:28 the mission had successfully launched
00:15:29 --> 00:15:31 another 21 styling Broadband satellites
00:15:31 --> 00:15:34 into orbit it was a record setting 23rd
00:15:34 --> 00:15:37 flight for the same First St booster
00:15:37 --> 00:15:39 number 1062a which had been flying since
00:15:39 --> 00:15:42 November 2020 following main engine cut
00:15:43 --> 00:15:45 off and Stage separation the booster
00:15:45 --> 00:15:47 performed its normal boost back burn and
00:15:47 --> 00:15:49 began its Journey Back to the surface
00:15:49 --> 00:15:51 everything seemed to be going nominally
00:15:51 --> 00:15:53 with a landing burn starting on time and
00:15:53 --> 00:15:55 the landing legs deploying just as
00:15:55 --> 00:15:57 planned but as the rocket touched down
00:15:57 --> 00:15:59 on the Drone ship a short full of
00:15:59 --> 00:16:01 Gravitas it appeared to have landed at a
00:16:01 --> 00:16:03 slightly higher velocity than normal
00:16:03 --> 00:16:05 causing the landing struts toplay out
00:16:05 --> 00:16:07 more than usual resulting in the engine
00:16:07 --> 00:16:10 builds appearing to hit the deck now
00:16:10 --> 00:16:11 that's what it looks like in the video
00:16:11 --> 00:16:13 and if that's what actually happened it
00:16:13 --> 00:16:15 could have damaged the motors releasing
00:16:15 --> 00:16:16 propellent and that would have explained
00:16:16 --> 00:16:18 the balls of flames separate from the
00:16:18 --> 00:16:20 rocket engine burn which was seen
00:16:20 --> 00:16:22 licking up one side of the booster and
00:16:22 --> 00:16:24 spilling Across The Landing Pad now as
00:16:24 --> 00:16:26 the hard Landing occurs one of the
00:16:26 --> 00:16:28 landing struts also buckles causing that
00:16:29 --> 00:16:31 Landing leg to collapse consequently the
00:16:31 --> 00:16:33 booster then tipped over into the cloud
00:16:33 --> 00:16:35 of flames at least that's the way it
00:16:35 --> 00:16:38 looks an investigation into the failure
00:16:38 --> 00:16:39 is now underway and will give you the
00:16:39 --> 00:16:42 results when they come out this incident
00:16:42 --> 00:16:44 could delay the next scheduled launch of
00:16:44 --> 00:16:46 a falcon 9 which would be on the Polaris
00:16:46 --> 00:16:48 Dawn Mission that's a mad orbital
00:16:48 --> 00:16:50 Mission organized by a billionaire
00:16:50 --> 00:16:52 entrepreneur Jared isaacman which will
00:16:52 --> 00:16:54 under take the historic first ever space
00:16:54 --> 00:16:57 walks by an all civilian crew the polara
00:16:57 --> 00:16:59 stor launch has already already been
00:16:59 --> 00:17:01 postponed twice the first time due to a
00:17:01 --> 00:17:03 technical issue with a helium leak and
00:17:03 --> 00:17:05 then due to bad weather conditions at
00:17:05 --> 00:17:07 the planned Landing site down range of
00:17:07 --> 00:17:09 Cape Canaveral it's worth pointing out
00:17:09 --> 00:17:11 that's the same Landing site which the
00:17:11 --> 00:17:14 starink booster used so are we dealing
00:17:14 --> 00:17:17 with a case of the SWR being too strong
00:17:17 --> 00:17:18 making the landing more violent than it
00:17:19 --> 00:17:22 should have been I guess time will tell
00:17:22 --> 00:17:24 this SpaceTime
00:17:24 --> 00:17:40 [Music]
00:17:40 --> 00:17:41 and time now to take another brief look
00:17:41 --> 00:17:43 at some of the other stories making news
00:17:43 --> 00:17:45 and science this week with the science
00:17:45 --> 00:17:47 report a new study has shown that simply
00:17:47 --> 00:17:50 wearing a face mask in public places
00:17:50 --> 00:17:51 could cut down your risk of common
00:17:51 --> 00:17:54 respiratory symptoms by at least
00:17:54 --> 00:17:57 3.2% a report of the British medical
00:17:57 --> 00:17:59 journal surveyed over 4 500 adults
00:18:00 --> 00:18:02 in Norway about their Lifestyles their
00:18:02 --> 00:18:04 use of face masks and their risk of
00:18:04 --> 00:18:06 infection and then asked half of the
00:18:06 --> 00:18:08 participants to wear a face mask when
00:18:08 --> 00:18:10 they were out in public enclosed areas
00:18:10 --> 00:18:11 such as shopping centers and public
00:18:11 --> 00:18:14 transport while the other half were
00:18:14 --> 00:18:16 asked to remain mask free while the mask
00:18:16 --> 00:18:18 participants reported lower rates of
00:18:18 --> 00:18:20 respiratory symptoms such as runny nose
00:18:20 --> 00:18:22 sore throat coughing and sneezing 80
00:18:22 --> 00:18:24 participants also reported feeling a bit
00:18:24 --> 00:18:26 silly about being the only ones wearing
00:18:26 --> 00:18:29 a mask in public while 40 reported fly
00:18:29 --> 00:18:30 uncomfortable because of breathing
00:18:30 --> 00:18:33 difficulties foggy glasses and poor mask
00:18:33 --> 00:18:35 fit which may have also LED them to
00:18:35 --> 00:18:37 avoid public places anyway despite the
00:18:37 --> 00:18:39 discomforts the authors say the results
00:18:39 --> 00:18:41 indicate that wearing a face mask in
00:18:41 --> 00:18:44 public could be a simple lowcost way to
00:18:44 --> 00:18:45 reduce your risk of catching a
00:18:45 --> 00:18:47 respiratory
00:18:47 --> 00:18:49 infection a new study warns that
00:18:49 --> 00:18:51 scientists may be missing millions of
00:18:51 --> 00:18:54 undescribed Extinction prone insect
00:18:54 --> 00:18:56 species a report in the journal insect
00:18:56 --> 00:18:59 conservation and diversity claims new re
00:18:59 --> 00:19:01 suggest that undescribed insec species
00:19:01 --> 00:19:03 were significantly smaller less abundant
00:19:03 --> 00:19:05 and less widespread than those already
00:19:05 --> 00:19:07 known about making them harder to find
00:19:07 --> 00:19:10 and more Extinction prone scientist in
00:19:10 --> 00:19:12 Borneo who are collecting Ro beetles in
00:19:12 --> 00:19:14 an area of tropical rainforest found
00:19:14 --> 00:19:16 that of the 252 different species of
00:19:16 --> 00:19:20 beetle they found 76% were new to
00:19:20 --> 00:19:23 science not having previously been named
00:19:23 --> 00:19:25 and it's not just other places in the
00:19:26 --> 00:19:27 wet tropical north of Australia
00:19:27 --> 00:19:30 scientists found that that among 107
00:19:30 --> 00:19:32 species of bark beetles identified 58
00:19:33 --> 00:19:35 were also new to
00:19:35 --> 00:19:37 science a new studies has confirmed
00:19:37 --> 00:19:39 earlier research that making kids take a
00:19:39 --> 00:19:42 break from screen time works wonders for
00:19:42 --> 00:19:44 their mental health the findings
00:19:44 --> 00:19:45 reported in the Journal of the American
00:19:45 --> 00:19:48 Medical Association reanalyzed results
00:19:48 --> 00:19:50 of previous Dy studies which looked at
00:19:50 --> 00:19:52 the effects of reducing screen time on
00:19:52 --> 00:19:55 kids and teens they found that a break
00:19:55 --> 00:19:57 from screens reduced problematic
00:19:57 --> 00:20:00 behavior and boosted good behavior the
00:20:00 --> 00:20:02 trials included 89 families with a total
00:20:02 --> 00:20:06 of 181 Children and adolescents screen
00:20:06 --> 00:20:08 time was reduced in 45 families while
00:20:08 --> 00:20:10 the others continued as normal in the
00:20:10 --> 00:20:12 families that curbed screen use the
00:20:12 --> 00:20:14 biggest improvements were seen in young
00:20:14 --> 00:20:16 people's emotional issues problems
00:20:16 --> 00:20:17 interacting with their peers and in
00:20:17 --> 00:20:19 being more caring and sociable towards
00:20:19 --> 00:20:22 other people however the troll really
00:20:22 --> 00:20:24 only looked at the benefits of reduced
00:20:24 --> 00:20:26 screen time in the short term and the
00:20:26 --> 00:20:27 authors say future studies should
00:20:27 --> 00:20:29 investigate whether these improvements
00:20:29 --> 00:20:31 can be sustained with longer term
00:20:31 --> 00:20:33 reductions in screen
00:20:33 --> 00:20:36 use Facebook and Instagram boss Mark
00:20:36 --> 00:20:38 Zuckerberg has confirmed that the Joe
00:20:38 --> 00:20:40 Biden Cela Harris White House demanded
00:20:40 --> 00:20:43 his company censor covid-19 content and
00:20:43 --> 00:20:46 cover up the hunterbiden laptop story
00:20:46 --> 00:20:48 falsely claiming that they were
00:20:48 --> 00:20:50 misinformation zacher BG consequently
00:20:50 --> 00:20:52 ordered legitimate debate removed
00:20:53 --> 00:20:55 account shut down and fair and balanced
00:20:55 --> 00:20:58 coverage either shadowed or silenced in
00:20:58 --> 00:21:02 a letter dated August the 26 2024 zacher
00:21:02 --> 00:21:04 BG told the United States House of
00:21:04 --> 00:21:05 Representative Judiciary Committee that
00:21:05 --> 00:21:08 he now regretted not speaking up earlier
00:21:08 --> 00:21:10 as well as other decisions he made as
00:21:10 --> 00:21:12 the owner of Facebook Instagram and
00:21:12 --> 00:21:14 WhatsApp around removing content
00:21:14 --> 00:21:15 detrimental to the Democrats and the
00:21:15 --> 00:21:18 Biden Harris administration of course
00:21:18 --> 00:21:20 it's not the first time Zuckerberg made
00:21:20 --> 00:21:22 the admission he said pretty much the
00:21:22 --> 00:21:24 same thing a few months earlier on Joe
00:21:24 --> 00:21:26 Rogan's podcast confirming that he
00:21:26 --> 00:21:28 ordered Facebook to restrict this story
00:21:28 --> 00:21:30 about Joe Biden's son Hunter Biden's
00:21:30 --> 00:21:33 laptop during the 2020 presidential
00:21:33 --> 00:21:35 election identical allegations about the
00:21:35 --> 00:21:37 Biden Harris White House were made last
00:21:37 --> 00:21:39 year in the Twitter files released to
00:21:39 --> 00:21:42 the media by Elon Musk commentators say
00:21:42 --> 00:21:44 it's more evidence that social media
00:21:44 --> 00:21:46 companies have become corrupt tools of
00:21:46 --> 00:21:48 government using their power to spread
00:21:48 --> 00:21:50 lies to manipulate the public for
00:21:50 --> 00:21:53 political gain many American voters say
00:21:53 --> 00:21:54 they would have changed their vote in
00:21:54 --> 00:21:57 the 2020 presidential election had they
00:21:57 --> 00:22:00 known the laptop store was real here to
00:22:00 --> 00:22:02 discuss Zuckerberg's stunning admission
00:22:02 --> 00:22:04 and what it means for social media is
00:22:04 --> 00:22:06 technology editor Alex Sahar of Ro from
00:22:07 --> 00:22:09 Tech advice. life people have suspected
00:22:09 --> 00:22:11 for a long time that you know Mark
00:22:11 --> 00:22:12 Zuckerberg that you know he just hasn't
00:22:12 --> 00:22:14 been truthful I mean the proof is that
00:22:14 --> 00:22:18 he's been on a 20 plus year apology tour
00:22:18 --> 00:22:20 for all the things he's done for playing
00:22:20 --> 00:22:22 fast and loose with people's information
00:22:22 --> 00:22:24 I mean he even in one of his original
00:22:24 --> 00:22:26 leaked SMS style messages with a friend
00:22:26 --> 00:22:28 of his when it was called the face
00:22:28 --> 00:22:30 Facebook but long before it was Facebook
00:22:30 --> 00:22:32 itself I mean he said look to one of his
00:22:32 --> 00:22:33 friends if you ever need any information
00:22:33 --> 00:22:35 on on you know his basically his friends
00:22:36 --> 00:22:37 and colleagues at the University was at
00:22:37 --> 00:22:38 he said I've got it all the pictures and
00:22:39 --> 00:22:40 photos and emails and phone numbers back
00:22:41 --> 00:22:42 in the days when they were rating
00:22:42 --> 00:22:44 females right yeah that's right yeah and
00:22:44 --> 00:22:46 Facebook started or the Facebook yeah
00:22:46 --> 00:22:48 now nothing has changed in all this time
00:22:48 --> 00:22:51 and he has built a giant like charged
00:22:51 --> 00:22:53 there should be a trial there should he
00:22:53 --> 00:22:55 should be judged before 12 of his peers
00:22:55 --> 00:22:57 I mean if anybody else had done this if
00:22:57 --> 00:22:58 Elon Musk had done this I me that'd be
00:22:59 --> 00:23:01 outrage and it's time to stop giving
00:23:01 --> 00:23:03 people a free pass just because they
00:23:03 --> 00:23:05 happen to be billionaires or the head of
00:23:05 --> 00:23:07 a of a major social media platform well
00:23:07 --> 00:23:09 they're doing that in France now aren't
00:23:09 --> 00:23:12 they I've seen it said on X that pavl
00:23:12 --> 00:23:15 you know was arrested for not giving up
00:23:15 --> 00:23:18 information and andk Zu head of telegram
00:23:18 --> 00:23:21 yeah and telegram is Accused by various
00:23:21 --> 00:23:23 governments and of other people for not
00:23:23 --> 00:23:25 having back doors and I saw him talking
00:23:25 --> 00:23:27 to Tucker talking about the FBI wanted
00:23:27 --> 00:23:29 him basically to put in back doors they
00:23:29 --> 00:23:32 tried to bribe or get his lead engineer
00:23:32 --> 00:23:34 to become a double agent so they could
00:23:34 --> 00:23:35 figure out which open source libraries
00:23:36 --> 00:23:37 were being used in the formation of
00:23:37 --> 00:23:39 telegram so that the US government and
00:23:39 --> 00:23:41 effectively any criminal could then get
00:23:41 --> 00:23:43 a back door into the entire system it
00:23:43 --> 00:23:45 started before then because people were
00:23:45 --> 00:23:48 noticing that they were being cancelled
00:23:48 --> 00:23:50 on Twitter as it was before Elon Musk
00:23:50 --> 00:23:52 bought it they were being canceled on
00:23:52 --> 00:23:53 Facebook I mean they were being
00:23:53 --> 00:23:55 suppressed but finally we're seeing some
00:23:55 --> 00:23:56 movement at the station in holding some
00:23:57 --> 00:23:58 of these people accountable what's
00:23:58 --> 00:24:01 Zuckerberg's motivation to come out now
00:24:01 --> 00:24:03 I mean it's almost the October surprise
00:24:03 --> 00:24:05 but it's a month early I would imagine
00:24:05 --> 00:24:08 he's trying to avoid uh you know going
00:24:08 --> 00:24:10 to jail being arrested that's Alex
