hey hey marcus house with you here we've
had quite a lot of
interesting updates at bogachika around
the orbital launch preparations
we have grid fin mount points for the
super heavy loads of tower stacking
starship 16 rolled away and may well be
destined for the first ever hypersonic
flight
we are diving right into all of that we
also have news on the
space launch system the three critical
elements of the artemis launch vehicle
are now together inside the vehicle
assembly building at kennedy space
center
spacex launched the gps3 sv5 mission
china launched three taikonauts to their
space station
rocket lab are going to mars yep you
just heard that correctly
then speaking of mars ingenuity had its
seventh flight
and perseverance rover begins its very
first science
campaign
we begin this week with news from the
launch site in boca chica
over the last few weeks we've seen rapid
progress with the launch pad itself
which will support the vehicle during
its flight campaign
the launch table itself that is
currently residing at the build site
will eventually be moved to the orbital
launch pad
and placed on top of the white legged
structure that we can see here
not a lot of updates on that but we have
seen hydraulics going in
so work is continuing here is the
massive integration tower which will be
used to stack the starship vehicle
on top of the super heavy that we
believe is going to stand around 144
meters in height
eventually this tower will also be used
to catch the returning booster as well
and we've been watching the construction
closely to see hints on how
this may occur the fourth section of
this orbital launch tower was lifted
on sunday last weekend and was stacked
late in the afternoon
on wednesday the fifth tower section was
stacked and on friday morning the
sixth tower section was rolled over to
the launch site additionally thanks to
rgv
aerial photography make sure you're
supporting there he captured photos of
the various parts
for section 7 of the integration tower
which were then
assembled soon after his flyover that
should leave i think
just one more eight in total while all
this stacking has been occurring brendan
lewis has been showcasing this great
infographic
which has been keeping us up to date
with the status of the launch
tower itself that has been very handy
for everybody following here so closely
now beside the orbital launch tower we
have the orbital tank farm which is made
up of three
cryogenic liquid oxygen tanks three
liquid methane
tanks a single liquid nitrogen tank and
then a non-cryogenic water tank
this week one of these cryo tank shells
which will help
insulate the cryo tanks underneath was
lifted over to the orbital tank farm
for a presumed test fit eventually it
will be permanently placed over one of
these
gse tanks now the stacking of a third
cryo shell began last weekend as well
and there's also a
large 12 meter water tank here that is
built with the same process of the
crystals
that water tank was rolled to the tank
farm last week
and it's already in position right here
the difference of course being that this
will contain a much larger volume of
water given the extra diameter
the test tank known as bn 2.1 had
another run this week as well
the test seemed to proceed through its
various stages uneventfully
so that is a good sign now back over
here near the launch tower a new
foundation for an unknown structure is
in progress
we've got no idea what this is for but
if you have any thoughts let me know
we're going to be keeping a close eye on
that
all the way over at the build site
booster 2 or whatever we're deciding to
call it these days
has had quite the week and we've had a
nice set of updates here to share
booster 2 was lifted to the front of the
high bay to stack the liquid oxygen tank
onto the thrust section
once the liquid oxygen tank is stacked
on top it completes
the lower section of the booster with
the next step of stacking the methane
tank
these two sections will then be mated
together to complete the entire booster
now we have here the forward dome sleeve
which is the section that sits right on
top of the booster stack
that was flipped as well now just take a
look at this
these holes that we see here are the
mounting points for the four
grid fins if you look closely enough the
arrangement is not the same
as what we've always expected this is
spacex's falcon 9.
the grid fins are placed equally around
the vehicle 90 degrees apart
whenever we've witnessed the falcon 9
come back to land we see this
very clearly now we've always just
assumed the super heavy booster would be
similar but it isn't
these holes are not equally spaced by 90
degrees
instead the two grid fins on each side
spread 60 degrees apart
with there being a 120 degree space
between the two sides
now i am assuming here that the main
reason for this is to provide more space
for the booster to come in to be caught
without the grid fins being in the way
of the tower
massive thank you there to jack bayer
with nasa space flight out there
capturing all of these images
make sure you're following jack on
twitter there too as he is always
dropping interesting images like this
that is a significant find right there
on monday the 14th of june these two
pieces were added right here
now many have been thinking that this is
part of a system used for catching the
booster out of the air
that is a total guess at this point but
i'm thinking that we may see some
significant reinforced parts be added in
this area if that is the case
remember back in april elon musk
specifically tweeted that the load
points
will be just below the grid fins this
point here is indeed
just below i've had a number of comments
suggesting that this can't be true as
there would need to be some kind of
shock absorption system
built into this remember though that
this shock absorption system will not
actually be built on the booster itself
but instead it'll be built into the
tower arms it makes
sense for the booster to be as simple as
possible and then spacex can build that
complexity into the launch tower itself
also in this area starship number 16 has
been rolled out of the high bay on
wednesday
and taken up to sit close by starship
15.
soon after elon announced on twitter
that they might actually use starship
number 16
on a hypersonic flight test he didn't
indicate whether or not this could
happen before sn20s orbital flight
so the timeline on this is unknown
having a starship fly fast enough to
exceed that barrier which is
typically anything between mach 5 and
mark 10
or a minimum of around 6 200 kilometers
per hour
will certainly be a first that is faster
by the way than a falcon 9 re-entering
the atmosphere
after its entry burn now i'm assuming
that they would still attempt to bring
this back to land on the landing pad
but perhaps they could choose to fly
much further out and ditch it in the
ocean
what do you think so we also had two
raptor engines delivered to starbase
last weekend on saturday morning
these were wrapped at number 72 with the
label philosoraptor
as well as raptor 74 called plaid mode
obviously inspired by tesla's launch of
the plaid mode
model s last week now in other news
spacex recently closed on the purchase
of macy's gun shop and range
on the way to starbase sources close to
this deal have indicated that this
location will be the raptor facility
and possible uses may include repair
rebuild and testing
of rocket engines now speaking of raptor
engines an
interesting graphic got a lot of
attention when spacex's ceo gwen
shotwell shared some footage while she
was doing her commencement address
with north western university we can see
her here strolling down the spacex
factory in hawthorne california
and if you look closely at this point in
the speech you can see here a screen
that says
starship orbital launch a number of
people out there of course have created
a version of this
to show it a little clearer firstly here
we see
countdown which reads 25 days 7 hours
and
30 minutes many have been assuming that
this is a timeline for the launch of
booster 2 and
starship 20 but keep in mind that this
video was pre-recorded when july 1st
was the goal for the first orbital
flight plans now have
obviously changed because with the
massive amount of work to be done
that goal is now impossible the board
also
shows which raptors have or haven't been
shipped to starbase
it shows in green that the center
cluster of super heavy engines and
two raptors for starship have already
been shipped and of course this
is out of date how crazy is that
so yes quite a lot going on there around
starship development
progress is super quick it is just so
thrilling to watch each and every week
and thank you all so much for
subscribing here to stay up to date
i launch these videos at the same time
every saturday and that is all because
of your support right there
just liking and sharing makes such a
difference to what i do
thank you very much now this week gave
us the best
live drone ship landing footage that i
think i've ever seen
i do realize i've said that a few times
now but hey they keep on getting better
just check this out this launch was for
the gps3
sv5 mission for the united states space
force
and the launch itself was just lit up
beautifully with incredible weather
once again greg scott out there
capturing these shots in glorious detail
we see here this beautiful view from the
falcon 9 there on the ascent
this was the 19th falcon 9 launch this
year and was also the first time a
booster has been reused by the us space
force
this same booster was flown once before
on the previous
gps3 sv4 mission we had the typical
engine cut off and stage separation then
all eyes were on the booster the footage
here
just mesmerizing i don't know about you
this still
blows my mind each and every time there
we go beautiful clear footage right down
to just read the instructions
which is of course the name of this
drone chip now even the camera signal on
the ship itself was flawless they are
really improving that signal big time
and i'm going to assume that starlink
has something to do with that
there we have the payload deployment
shot and yes another terrific mission
from spacex
that never gets old now we have some
space
launch system news for the first time
the three critical elements of the
artemis launch vehicle are now together
inside the vehicle assembly building at
kennedy space center
over the course of two days a heavy lift
crane carried out a methodical slow
choreographed
transfer of the core stage from the
transfer aisle over to the mobile
launcher
this massive stage weighs in at over 85
metric tons and it stands around
65 meters tall the core stage was
lowered in between the two 54 meter
solid rocket boosters
in high bay 3. the artemis 1 uncrewed
orion capsule test flight will be the
first to return towards the moon
since apollo 17 in 1972
of course the goal for the capsule is to
travel out beyond the moon before
returning to earth with the mission at
lasting
three weeks so what comes next is that
the launch vehicle stage adapter which
connects the core stage with the upper
stage
will go on top this will then be
followed by the interim cryogenic
propulsion system
and then the umbilicals which will be
connected and
powered up the orion stage adapter will
then be stacked and a
mass simulator will be placed on top
that will sit in place of the european
service module
orion crew module and launch abort
system also known as the orion
multi-purpose crew vehicle
now the first mission with crew for the
new chinese space station launched
this week as well this was a long march
2f vehicle
and on board for this mission was three
taikonauts this is
actually the first crude flight from
china in about
five years they have already boarded the
station soon after docking on thursday
and they'll be spending three months on
board here before returning home
we are going to be seeing a lot more
activity in the near future as well
because this is only the third of 11
launches involved
in building out the space station that
should be completed sometime
in 2022 on a tuesday some eagle-eyed
twitter users noticed that rocket lab
had filed a trademark request
for a new engine called archimedes this
is very exciting to see
because it's most likely the name of the
four first stage engines
for the upcoming neutron rocket that is
of course rocket labs
new partially reusable medium lift
launch vehicle design
interestingly on the same day rocket lab
announced that it had been
awarded a contract to send two photon
spacecraft to mars
now these are going to be used in nasa's
upcoming escapade mission
this mission is going to involve having
two spacecraft orbiting mars
to study the structure composition
variability and structure
of the martian magnetosphere more
specifically how
solar winds have stripped it away over
time this
is essential information for humanity to
understand before any distant future
terraforming systems
could be used successfully many people
have in the past
discussed a variety of ways to terraform
mars but will need a
much better understanding of such a
process well before any such plan
could be established so the two photon
spacecraft named blue and gold
will be launched in 2024 on board a nasa
provided rideshare launch vehicle
they will then begin an 11-month
interplanetary coast
before arriving at mars to begin their
year-long mission
escapade aims to demonstrate a
cost-effective interplanetary mission
with rocket labs ceo peter beck saying
that they want to deliver big science
in a small package now while we are over
here at mars the helicopter ingenuity's
recent
seventh flight speaks volumes of the
robust design of this heroic little
rotor craft
after flight 6 had the issues during the
second leg of the trip
it still managed to power its way along
staying aloft before making a safe
landing
near its intended landing site this time
around though
no such issues at all with ingenuity
flying for just over one minute
and covering a distance of 106 meters or
348 feet
in a southerly direction touching down
in airfield
number four after all of these
successful flights the mars rover
perseverance is now focused on science
tasks as opposed to
observing the flights of this
history-making helicopter
speaking of the helicopter ingenuity
there is a terrific documentary about
the future of such drones
right here and thank you very much to
curiositystream for sponsoring today's
video
curiosity stream of course is an
incredible subscription streaming
service that i've been subscribed to
myself
for years the content here is exactly
the stuff that inspires me to follow
what i do here on the channel
drones have already provided incredible
value on earth
the mars helicopter is proving to be
extremely successful so far
and that is with the incredible
challenge of flying in the minuscule
atmospheric density
that exists on the red planet research
in these drones
doesn't stop here though all of this
paves the way for an even
more exciting future this episode of
breakthrough talks about dragonfly which
is a
future daring mission to saturn's
largest moon titan
that aims to find prebiotic chemical
processes that are common both there
and here on earth that is set to launch
in 2026
and will be the first time that nasa
will fly a multi-rotor vehicle on
another planet
or moon there are so many questions and
answers that are explored right here

so along with ingenuity updates we have
a few quick things to catch up with in
regard to the
mars perseverance rover that has
essentially now completed all of its
system tests
the automatic navigation and sampling
systems are not fully online as yet
but they will be once perseverance
reaches its first site of interest
south west of the octavia e butler
landing site is a low-lying area that
overlooks jezreel crater
it is here that the rover will collect a
sample or two from four sites of
interest
in what is thought to be an ancient area
once covered
by at least 100 meters of water when the
science team is satisfied to hit the
road again perseverance will head back
to the landing site before heading north
and then west to the fan-shaped delta
region
this zone of a once merging river and
lake could possibly be carbonate mineral
rich
and contain signs of fossilized ancient
life
the green area that you can see here
could possibly be the ancient shoreline
of lake jezreel i can't wait to see what
they discover here
could they perhaps find signs of past
biological activity
i'm interested to know what you think
now if you're wondering why we haven't
seen any more starlink launches yet that
is because the initial shell is complete
the next launch will actually be
starting off a set of polar missions
with the first to be launched sometime
in july
a quick special mention as well for the
nrol 111 flight from wallops
because it isn't every day you get to
see a giant banana
unzip at launch also i just had to show
this image here shared by nasa last week
i'd missed it at the time but this here
is an image of jupiter's largest moon
ganymede
which was taken by the juno cam imager
during juno's flyby
on june the 7th it flew closer to
jupiter's largest moon here than
any other vessel in more than two
decades each pixel of this image
represents around one kilometer it is
just
mind blowing so yes remember as well
that 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
