thank you to brilliant for sponsoring this video hey hey marcus house with you here and it has been
a strange week in the space industry the launch of starship sn10 was stifled by bizarre weather
in texas but plenty of progress was still seen around the construction and launch sites for the
first time in almost a year a falcon 9 booster was lost after a successful starling mission
we'll dive into that some updates on united launch alliance's vulcan centaur pathfinder rocket but of
course the big story the perseverance rover this has been yet another incredible week
so yes this week at boca chica texas starship development certainly has not gone to plan as
we had hoped we were geared up for a static fire early in the week followed by a potential launch
of starship sn10 but the weather had other ideas texas was hit by an extreme burst of
winter weather this week slowing the plans and preparations for a static fire test
and a launch mary aka boca chicago with nasa space flight did not stop though she was out there
in below freezing temperatures as tweeted here early in the week it was 26 degrees fahrenheit
or just under -3 degrees celsius with ice on the vehicle mary pushed on what a trooper thanks mary
for all you do out there recording history so yes given the struggle with weather spacex appear to
have taken the opportunity to speed up work on the orbital launch pad being that it is impossible to
work on or test sn10 in these conditions with the sustained 50 to 65 kilometer hour winds
rain and below freezing temperatures it is clear that spacex needed some serious infrastructure
progress for the next step for starships so trying to work it with weather and with faa
approvals pending at the time made total sense to me remember that every time they need to test a
starship the pad needs to be cleared and work on infrastructure has to be stopped sometimes
for several days in a row so yes a lot of work has been underway at the orbital launch site some very
interesting new components were spotted arriving and being put together this here looks to be the
launch table for the orbital launch mount a 3d artist on twitter by the name of old bl
created a render here of what this could possibly look like these great shots from
rgv aerial photography here also show three rings of rebar on the new foundation that we mentioned
in last week's episode now just heading into a little speculation here it seems most likely to
me that this could be the start of the new tank farm for the orbital launch pad twitter user pair
of ducks created this render here of a possible trio of nitrogen methane and oxygen storage
tanks atop concrete stands let me know what you think this rebar is for in the comments below
now along with all that of course we've seen a lot of work going on with the actual landing
pad after sn9's recent failed landing attempt this beast really bit the dust hard here and since last
week they have actually decided to pour concrete over the entire pad raising it it seems by roughly
half a meter or so thanks there to dayton as well down there on site capturing some great
new footage so yes sadly no chance for a flight but we did get some interesting information such
as the tweet here from some dude here asking for opinions on the outcome of the flight
can they master that flip and stick the landing the audience there gave it a 64 chance of landing
well elon musk provided his opinion of success saying that the landing probability is around 60
fairly consistent there it seems with public opinion interestingly this is up from the one
out of three chance that elon suggested for sn8's flight now along with this information declan here
who is the master of flight analysis having created flightclub.io overlaid telemetry and
other data for sn9's official live stream just to demonstrate how a falcon 9 style live stream
could look elon musk responded to this saying that it was a good analysis even more interesting is
that spacex are currently working on lowering the minimum throttle capability of their raptor engine
which would allow extra redundancy for the landings themselves now currently that minimum is
publicly reported at least to be around 40 thrust which were the figures tweeted by elon last year
even back then though elon stated that both merlin and raptor could throttle much lower
with the added design complexity so yes it looks like that is underway already and with this larger
range of throttle starship and super heavy will both benefit so yes that is about it for
updates around the launch site heading over to the build site now work certainly did not stop for
the weather starship serial number 11 had its two aft flaps mated to the side of its hull this week
the flaps are usually the last main component to be installed before moving that vessel to the
launch site so we're wondering now is it possible that due to sn10s delays we could see sn11 next
to sn10 down at the launch site after sn9's epic landing fail near sn10 the other week i would have
thought not but spacex certainly seemed to be in a rush to get sn11 ready to fly i'm thinking more
and more that spacex are actually pushing forwards towards sn15 which is the next in line after sn11
for those that are wondering why the jump in numbers there it's because sn 12 13 and 14 were
all halted after being started and have since been discontinued that flight of sn8 alone successfully
passed off on the majority of flight goals that each of those iterations were intended to test
hence they have all been skipped i think the advancements on sn15 are substantial enough
that they could be willing to risk a little collateral damage to see sn15 rolling to the
pad as soon as possible what do you think though will sn11 join sn10 on the adjacent launch stand
i'm interested to know what all of you think let me know in the comments below now speaking of sn15
its nose cone was spotted by mary inside one of the tents and now looks to be ready to be stacked
on top of the nose barrel which is already waiting outside in front of the low bay additionally two
aft flaps arrived this week for sn15 due to it being in the mid bay and not yet prepared for
aero cover and flap installation the two flaps were placed on a steel beam structure in storage
awaiting their movement to join sn15 as of right now sn15 is still awaiting for its thrust dome to
be mated with the rest of the upper tank section one of the most interesting photos of the week
was actually what was spotted right here can you see what this is does that look familiar to you
to me this looks to be a grid fin section which we can only assume is for the super heavy booster
after some masterful sleuthing by the community this piece measures roughly 2.3 meters by around
3 meters much smaller than would be expected for a full super heavy grid fin the thought that we're
having here is that this is just a section for what will be a fully assembled grid fin it could
perhaps be a demonstrator or pathfinder prototype neopork here who tweeted about this earlier in
the week thinks that perhaps this is the short end of it as shown right here we are waiting
to hear a lot more about that grid fin also along with that we had a sneak peek here at a real life
naked raptor engine out in the wild after being refurbished this is raptor serial number 27 which
powered the single engine flight of starship sn5 for its 150 meter hop last year this little beauty
has returned this week for reasons unknown not sure what's going on there so yes to sum
up the week as always we have brendan's latest diagram here keep up to date with developments
here on his twitter feed of course and please do consider subscribing for regular updates here
all of your interaction from likes and comments helps so much more than you would even believe
and we can create even better content because of all that thank you as always for coming back and
keeping up to date with us here so yes now the even biggest story of the week was of course
the perseverance rover and i'm so thrilled that it was a good outcome around 10 minutes before
reaching mars atmosphere the cruise stage carrying perseverance and the little helicopter ingenuity
separated from the aeroshell after separation that cruise stage was of course left to just
burn up in the atmosphere whereas the aeroshell containing the rover and sky crane continued on
for its controlled entry the aeroshell there is comprised of two halves the heat shield
and the reverse side called the back shell both of those sections together of course encompass the
mars 2020 payload protecting the vehicle on the long trip there as well as of course in the most
terrifying part of the mission entry into mars atmosphere this is what is referred to as the
seven minutes of terror and that's because it takes about seven minutes for the spacecraft to
travel from the top of the martian atmosphere down to the surface as the vessel entered the
atmosphere it was up to the 4.5 meter heat shield to come into play with a velocity over 20 000
kilometers per hour the aeroshell encountered the thin martian atmosphere with the heat shield
reaching a sweltering 2100 degree celsius all while keeping the payload safe the aeroshell's
uniquely shaped design of course produces some lift which essentially helps reduce the speed as
it descends keeping it in the atmosphere a little longer helping it to bleed off speed reaching its
targeted 1 370 kilometers per hour now at this moment the ballistic parachute safely deployed
at around 11 kilometers in altitude the vehicle continued to slow down as it dropped past eight
kilometers in altitude and the heat shield was jettisoned shedding mass in that process with
about one minute remaining of the descent time the parachute had fulfilled its purpose by reducing as
much velocity as it could the martian atmosphere of course is incredibly thin compared to our own
with a surface pressure less than one percent of what we find here on earth in fact mars atmosphere
density is so low that the only way for a rover this massive to slow down anymore and land safely
was propulsively and that is exactly what this vessel did just like back in august 2012 as we
witnessed with the curiosity rover it is of course the proven sky crane delivery method and this
incredible awesome piece of engineering just never ceases to amaze me the sensors there detected the
ground contract triggering those pyrotechnically fired blades that severed the cables from the sky
crane which then flew off and crashed well away from the landing site with the rover there sitting
safe and sound it reported its success back to earth as we waited anxiously like we did back
when curiosity landed everyone was turning blue waiting for that mission success message and
with that message then received and the tension relieved the real fun can start its landing site
here jezreel crater is scientifically significant due to it having been a lake in the distant past
with water flow coming into the crater as well as exiting via the outflow channel leaving distinct
remnants of an ancient river delta so this is a very good location to search for historic signs
of microbial life which is really the main objective for this high high-tech beast of
course the study of mars climate and geology is also very important there with the rover assigned
the very important job of gathering rock and soil samples for analysis and to then beam the results
back to earth it's also going to hold samples in special sealed storage tubes for future collection
and a potential return to eager scientists here on earth as well along with the rover we have an
added extra an autonomous drone helicopter named ingenuity which was attached to the underbelly of
the rover as we see here now this little beauty is an experiment to test how well a vehicle like
this can fly in the super thin martian atmosphere and to map out the surrounding area so yes this is
going to be an incredible mission with all of the sophisticated instruments that both perseverance
and ingenuity has on board we have much better camera equipment on this version of the rover
as well as audio capturing capability for the very first time which is built into this beast as well
perseverance is going to provide incredible new scientific information what do you think will we
be likely to find signs of historic microbial life on mars let me know in the comments below
it is going to be extremely exciting to watch this mission play out that much is certain also i just
wanted to say a massive thank you to tony bella here for creating this amazing infographic for
the community a true work of art here just check out the incredible amount of detail
just jam-packed into this one infographic you can pick up the high-res version of that completely
free from his website there shown on screen as well so generous of tony here making this amazing
material available for free make sure you're following him on twitter there for much much more
so yes it was time once again for another starlink launch this week and it was from
pad 40 at cape canaveral space for station at 10 59 pm on monday february 15th the countdown
to launch proceeded as planned with yet another 60 starling satellites safely stowed away in the new
fairing halves we saw a glimpse there of miss tree and miss chief on station are waiting to assist
with their recovery efforts with the liquid oxygen loading complete it was time to clear the line
on the transporter erector with some nice venting taking place here just before falcon 9 entered the
startup phase with one minute to go with a rapid series of final system checks completed it was go
time with the nine merlin engines thundering to life streaking skyward there once again we had the
stage one telemetry readouts keeping us informed of the uphill climb with the main engine cutoff
and separation successful it was time to pop those fairings and the second stage continued on its way
to orbit while the booster headed back to meet up with the drone ship
of course i still love you with the entry burn shutdown announced at approximately 32 kilometers
in altitude there still seemed to be some sort of activity right down to 21 kilometers where we lost
the telemetry readouts even the webcast host jesse anderson sounded a little unsure at this
point the cross to the live view for the drone ship showed a faint glow in the background
that quickly disappeared with what was surely a loud impact startling the birds there on the
deck of the drone ship so unfortunately this meant a crash landing for booster number 1059
after this sixth flight now the last time spacex lost a first stage was way back
in march of 2020 when the booster suffered an in-flight engine failure with the resulting
landing attempt not going to plan so yes despite clearly losing the booster at this point of the
webcast the mission continued with the second stage completing orbital insertion and payload
deployment that completed the mission objectives for this flight and it just goes to show that
even when things don't go 100 to plan spacex can still nail these missions very impressive stuff
so on top of all of these updates we've recently got to finally witness the vulcan sentinel booster
as it made its way from the rocket ship at port canaveral in preparation for the launch site
testing more on that in a moment but first a big thank you to brilliant for sponsoring this video
now we obviously love the science and math related topics here and it's not hard to see why
sadly these subjects if not taught correctly can limit the enthusiasm that can be had
from understanding these incredible languages of our universe now what do you think is the best
way to learn something is it through lectures or exercises from a textbook maybe well i don't
think so the research is clear and it shows that problem solving is a much more effective process
that is exactly what brilliant is it's a website and an app built off this very principle letting
you learn effectively while solving problems in real time you don't need to sit down and memorize
a bunch of long drawn out formulas or drill endless facts into your mind it's all about
intuitively understanding what and why you are solving problems in these ways there are no tests
and no grades you just pick up an area of interest and away you go start by having fun with the
interactive course components and before you know it you'll be amazed at what you've learned thank
you very much to brilliant for their support of my channel here and if you would like to
support me and would like to give it a try go to brilliant.org marcus house the first 200 people
will get 20 off the first year of brilliant premium the link is in the description below
so yes wonderful photos here taken by greg scott who was out covering the roll out of the vulcan
centaur booster there are much more on his twitter feed too so make sure you are following greg there
so this is it united launch alliance's newest rocket which will take over from the tried and
true atlas and delta rockets the vessel we can see here is not actually going to fly but it's more a
pathfinder stage which will be used to ready the team and ground facilities for a future launch
for those that are unfamiliar this vulcan rocket is a brand new offering from ula
designed with high performance in mind along with it being a lower cost option for those riding the
rocket into low earth orbit and beyond this is going to be available in four configurations
it can fly with one on either side in a double configuration it can fly with four or even six
srbs what is quite unlike their previous rocket such as atlas which uses rp1 or the delta series
using liquid hydrogen as the fuel vulcan follows a similar mixture to spacex's starship using liquid
methane there are a lot of advantages to that fuel mixture as we've explained in previous videos now
what i'm really wanting to see is the first stage engines here fire up in the future these are the
b4s which are of course engineered by blue origin the first launch of the vulcan is scheduled to be
the incredible peregrine lunar lander the very same that is taking the i need more moon project
by tj up to land on the moon with around 15 000 names all included i just can't wait to see that
beast take off in fact there is already close to 30 launches booked in on this new vessel as
tweeted by united launch alliance themselves that is no small achievement and i certainly can't wait
to see the first mission launch under the power of those awesome engines interestingly these are
of course the same engines that will be launched on blue origin's own new glenn rocket once that's
ready to fly speaking of new glenn we got a small glimpse of what appears to be a booster in
progress here from stephen on twitter and we don't often get to see a peek inside blue origin so that
is a nice find like i've said a few times before blue origin may just roll out a full rocket ready
to launch with none of us being the wiser that was kind of a joke but seeing this makes me wonder if
that actually may well be the case now we are huge supporters of the transition to electric vehicles
here on the channel and our partner ev offers the ability to hire an electric vehicle in australia
perhaps you have wanted to take an extended test drive you could be touring the country and want to
drive around in a tesla if that sounds appealing to you you can use the link in the description
