this video is sponsored by squarespace the  all-in-one platform to build your beautiful   online presence and run your business hey hey  marcus house with you here some delays this   week on the flight of spacex's starship serial  number 11 which is hopefully going to take its   flight within days now but still loads to  talk about with the bokeh chica sites and   upcoming prototypes including the first fully  stacked super heavy booster some fantastic news   for relativity space this week with their  first launch contract with the pentagon   an amazing sls hot fire and updates as well  on hubble and the james webb space telescope so yes history repeated itself a little again  this week with static fire delays the static fire   test that was expected by the end of last week  had issues related to ground support equipment   which delayed the event until monday morning the  thought was that we could have a static fire and a   potential flight within a few days after that this  plan quickly slipped as just a milliseconds before   sn11's first static fire and abort was called  right before full ignition briefly leaving the   rocket on fire what happened here is that the  starship prototype momentarily ignited one   or two of its three raptor engines pre-burners  which is an initial step before igniting the   main combustion chamber on the plus side though  progress has already been made for the upcoming   flight with the federal aviation administration  formally authorizing the flight early in the week   as stated here the faa found no public safety  concerns with the initial sn10 mishap report that   would preclude further launches as a result the  faa approved the license modifications for sn11   and authorised its flight hopefully that will be  coming very soon now so keep your eye on those   launch notifications now while on the topic of  starship flights in case you had not spotted it   spacex released a new video of sn10s flight on  tuesday this week and wow there is some amazing   new unseen footage worth touching on this video  shows footage from the on-board cameras themselves   adding a few new perspectives that we haven't  seen this shot here shows the terrific view   of the forward fins controlling the vehicle on  descent those heat shield tile attachment points   that we can see there on the liquid side of the  fin are shown in beautiful detail likewise we   see a view looking straight back towards the  aft side of the vehicle again we can see those   heat shield tiles applied right there i think the  most noteworthy part of this footage though was   the flip and landing which certainly shows a great  perspective of the rocket engines as it comes in   for that landing if we pause right here you  can see a little burst of green flame pop   out of this shutdown raptor a clear sign as elon  musk said on twitter that the engine is burning   internal components made of copper typically  not a very good thing also another terrific   view there of the landing legs that had not quite  all locked themselves into place thanks spacex for   again releasing this awesome footage i was kind of  hoping the explosion afterwards might be included   but all the same terrific stuff now for the first  time ever spacex has fully stacked a super heavy   booster essentially completing the assembly of  the largest rocket booster ever built work remains   of course to complete the assembly welding and  fully connecting the plumbing and avionics this   massive beast consists of 37 steel rings and  stands roughly 67 metres tall huge thanks to bogo   chicago and jack bayer with nasa space flight for  the amazing and ever increasing coverage this week   what was very interesting and shared by nasa space  flight was a spacex document which includes a lot   of new information about their future prototype  testing schedules now up until this information   was released the thought was that booster number  one here would take flight sadly though that is   not the case instead it will now be rolled to the  starship suborbital pad for ground testing only   including cryogenic liquid nitrogen tests and  potential static fires these tests will provide   vital data ahead of booster number two's test  flight which is currently planned to take to the   sky booster number one's test campaign is expected  to occur just before sn15 goes to the pad for its   test flight then once sn15 is complete and begins  its testing campaign the beginning of what is   likely to be a new high altitude test campaign  will begin involving three starships with sn16   and 17 joining along now this is a similar  structure i guess to what we've been seeing with   sn8 right through to sn11 targeting the complete  medium altitude testing campaign if these tests   are successful it is possible that spacex will  skip sn18 and 19 and go straight to attempting   an orbital flight test involving super heavy bn3  and starship sn20 with a goal to get to orbit by   july 1st that is a crazy test campaign even if it  remotely turns out to be true now a huge amount of   work is also taking place over at the orbital  launch site which will obviously be utilized   for the orbital starship testing campaign this  site will eventually host two super heavy mounts   according to a document that we talked about more  in depth in last week's episode the first mount is   nearly complete and is awaiting its launch table  the construction of the huge integrated tower that   will include a crane to lift and mate starship  with a booster has also begun construction seen   in a picture by rgv aerial photography's photos  here and yes elon's crazy idea of catching the   booster out of the air eliminating the need for  landing legs is a core focus as crazy as that   currently sounds spacex sure does have a habit of  making the crazy possible additionally more pile   driving occurred near the orbital launch pad and  this new driving could possibly be for additional   commodity storage for the pad as it's right next  to the ground support equipment and tank farm   so we are currently working on our model of the  launch site itself similar to the construction   site that we showed the other week it is still a  work in progress and everybody really loved our   breakdown of the construction yard a few weeks  back so we thought we'd continue with that idea   here thanks a heap to everyone for the terrific  feedback on that segment all of you out there   subscribing liking and sharing makes such a huge  difference to us here rapidly coming up to that   300 000 subscriber mark and that is all because of  you right there thank you very much now regarding   future starships sn15 is currently in the mid  bay awaiting its turn to enter the high bay for   nose cone stacking the massive blue zilla crane  was rolled to the build site at the start of the   week to receive a luffing jib extension to finish  bn1 stacking then on thursday shortly after seeing   this amazing shot here by austin barnard we also  got this magnificent perspective from elon musk   showing the full extent of bn1 right up the high  bay and all the way out through the hole made   for the crane there this is the first big step  towards making starship fully orbital so we've   got to take a look now at what they are doing in  regards to the re-entry thermal protection systems   the patches of the thermal protection system  ties on current and previous starship prototypes   have been used to test how the material and its  attachment points react during propellant loading   and flight stresses with these future  orbital starships such as starship   sn20 and beyond the vehicle's entire windward  side should be applied with those heat shield   toss that is certainly going to be required for  missions that will see starships return from space   and endure that extreme re-entry heating now just  stop and think about this for just a moment this   will be the most massive vessel to ever attempt  an orbital re-entry with the intention to land   and be reused the space shuttle of course did  this as well and it was still quite a large vessel   but starship is much larger again one of the big  issues with the shuttle's heat protection system   was its complexity the very intricate layout  of the heat shield tiles here was extremely   expensive to maintain in many areas there were no  two tiles the same size and this made it a monster   job to construct the vessel and maintain it now  comparatively the starship tiles we see here   in this great piece of footage by jack are made  to be the same size and are very quick to apply   we have seen different sized tiles in various  tests as well but we would assume that spacex   will either settle on one size or even perhaps a  few standard sizes for coverage of more intricate   areas at this point i wouldn't be surprised at  all to see a near-complete coverage of thermal   protection system tiles even before sn20 as it  would make even more sense to test a more complete   system prior to tests at orbital re-entry speeds  now while we're talking about future orbital   starships it's important to add that a test  mount for starships of vacuum raptors was spotted   and installed to a practice rig we'll talk about  that more in a moment but just quickly a

so yes back to the test mount for the starships  vacuum raptors three of these mounts will be   placed around the dome which was left over from  the planned sn14 test article these raptors have   a higher specific impulse in vacuum conditions  than the c-level engines which have been used   on starship flight tests up to this point these  need to be utilized to place starship into orbit   and for other burns to go to the moon or mars the  known efficiency target for those vacuum engines   is a specific impulse of around 380 seconds which  is far higher than the sea level engines optimized   for lower altitudes now for those that are not  familiar with specific impulse it's essentially   a measurement of efficiency comparable i guess to  miles per gallon or kilometers per liter so the   higher the better at the construction site major  tent expansion is also underway at the nose cone   assembly tent also known as tent three we have  some updates finally with the test tank sn 7.2   which is made from the thinner three millimeter  steel this was rolled out of the launch site and   back to the construction site for unknown reasons  it was assumed that a final test would take place   where they purposefully fill and pressurize  the tank beyond limits until it bursts however   it seems like this is not the case anymore is  it possible that repairs are being made to it   before a more complete test to destruction or is  this the end of the road for sn 7.2 let me know  

what you think in the comments below so along  with all of the other starship updates for the   week i've just got to drop some teasers for an  epic first collaboration between neopork corey   and alex spann and from what i've seen so far i  think it is going to blow everyone's minds what   they are working on is an animation project that  will push all of their limits neopork here focused   primarily on rocket modeling and detailed texture  work corey doing the bulk of the rigging animation   and alex supplied his insane raptor engine  models which he has reworked to be more animation   friendly none of this would have been possible  without the amazing reference photos and videos   from everybody that is down capturing footage and  photographs from boca chica this is what we are   always talking about team space what the entire  group can do collectively is just astounding   what is coming up here between nino pork corey  and alex in a dream team collaboration is some   stuff that is going to be quite incredible make  sure that you're following their twitter accounts   and youtube channels because the hype is real  for this next level stuff i can't wait to see it   now we have a brand new record breaker from the  starlink mission early in the week with a booster   1051 becoming spacex's first ninth flight of the  exact same falcon 9 booster beautiful shots here   of it by greg scott yet again thanks greg this  instantaneous launch window saw the booster set   to be the very first to fly for the ninth time  with another 60 starling satellites on board for   this the eighth mission for 2021. this boosters  previous launches were five starlink missions   sxm7 radar sat and of course the crew dragon  demo one mission which was carrying ripley   a human-like test dummy and a zero-gravity  indicator in the form of a toy earth during these   webcasts i always love hearing about how starlink  is already having a positive impact especially   for remote communities north carolina announced  recently that swain county and hyde county were   now providing students with high speed internet  oracoke island typically has adverse weather and   flooding which impacts school attendance now  thanks to dishy mcflatface here high-speed   internet is greatly assisting students in these  communities just awesome news there now with   an on-time liftoff this record-setting booster  streaked its way to main engine cutoff in no time   at all the second stage separation was seamless  and some great visions here of the merlin vacuum   ignition and throttle up with successful fairing  separation the satellites were well on their way   to the drop-off orbit to begin their service life  after a successful entry burn the glowing deck of   the drone ship of course i still love you hinted  that the booster was on target unfortunately   the camera link failed briefly but here we go the  first successful return of a booster for the ninth   time this also marked the 77th recovery of a boost  overall and 65 minutes after liftoff it was time   to release another batch of 60 satellites seen  here slowly drifting away to complete yet another   successful mission it really is mind-blowing just  how much master orbit spacex alone is punching   out as elon tweeted this week spacex alone put up  double what the rest of the world did combined in   2020 with this year aiming for 300 to 400 more  that is a paradigm shift that is changing the   industry very dramatically now we also had the  incredible sls eight minute hot fire occur on   thursday as part of the green run test of the core  stage this was essentially the last step before   this stage will be sent to kennedy space center  to launch the orion spacecraft on the artemis   1 mission this test completed the full duration  hot fire after the previous attempt was cut short   due to hydraulic system issues with one of the  engines which was exceeding the safety parameters   that only managed 67 seconds or so well short of  the time needed to complete the tests adequately   this space launch system core stage booster is  of course built by boeing and is fueled with   liquid hydrogen and liquid oxygen these four rs  25 engines pack a massive punch at an estimated   1.6 million pounds of thrust or just over 725  metric tons of force nasa and boeing should now   have enough data to determine if it is ready to  launch that is going to be an incredible sight to   see that flight with an uncrewed orion spacecraft  is scheduled roughly very late this year   or early 2022 hopefully that remains on track  in some other topics some fantastic news from   our friends at relativity space this week they  have signed their first pentagon launch contract   the defence innovation unit chose relativity  space as a launch provider for a small   u.s military payload for 2023 using their terran  one launch vehicle terran one is due to make its   first flight later this year from cape canaveral  now we have covered relativity space in past   episodes discussing their pioneering manufacturing  process of creating fully 3d printed rockets   not only is terran one in progress but development  is currently underway to create a fully reusable   launch vehicle that is entirely 3d printed this is  dubbed the terran r and will be a size similar to   falcon 9 as described by co-founder and ceo tim  ellis as a natural evolution from the terran one   the big difference here is falcon 9 is only partly  reusable whereas relativity plans to build some   pretty exotic products to pull off second stage  reusability as well exciting stuff there guys   as for landings the terran r may possibly use two  landing options either at a concrete pad or on a   drone ship these guys just blow my mind with their  revolutionary approach to rocket construction   and minimal individual parts required as well as  driving down the cost of launches for its current   and future customers with a terran one launch  in the vicinity of 12 million dollars per launch   it will be capable of carrying 1250 kilograms to  low earth orbit the terran r on the other hand   will be capable of lifting over 20 000 kilograms  compared to falcon 9 at 22 800 kilograms to a low   earth orbit if you imagine being a customer with a  spacecraft needing a ride into orbit trail blazing   companies like relativity will be strategically  placed to offer very competitive launch options   relativity's presence as a launch provider will  greatly serve a market where it is forecast that   there will be a launch shortage in the years  ahead that innovation just blows my mind and   developing or even making a change to a design in  current aerospace factories is a very slow process   also involving others in the supply chain with 3d  printing technology these designs and changes can   happen much quicker congratulations once again  to all of you there at relativity space on your   first defense contract signing now a few updates  here on the hubble space telescope the 30 year   old marvel of science is once again back online  after a software glitch put it into a safe mode   just recently the telescope was offline for four  days as engineers diagnosed the issue as being   caused by an upgrade which was uplinked to it one  of the gyroscopes had been causing some issues   and the patch unintentionally caused a wider  issue with the on-board computer resulting in it   protecting itself on march the 7th as fate would  have it this issue identified other areas needing   attention including the aperture door which did  not close as intended when a safe mode event is   triggered that door there protects the optics and  instruments from damaging sunlight the wide field   camera 3 also suffered an as yet unspecified issue  and observations now remain on hold in that area   hubble of course was launched in april 1990 and  is showing its age with differing views now on   how long it's going to be able to keep  working with no space shuttle to do some   servicing as it's done in the past they simply  do not know how long hubble is going to last   any major problem at this point and its mission  is all over thankfully though there is the james   webb space telescope waiting in the wings granted  it has taken way longer to develop than anyone   would have thought over 20 years in fact with its  share of delays and issues ranging from technical   managerial and financial then of course  the general pandemic related delays as well   this has been a huge process but this is one  recent development that you may find surprising   later this year nasa plans to finally ship the  telescope to its south american launch site   via the panama canal interestingly the agency  staff are concerned a little about pirates yes   pirates not something that you would normally  think would be a concern for space projects   i mean we're not exactly talking about the peg  leg and the parrot type pirate but there could be   people out there who are potentially entertaining  the notion of hijacking the ship with its 10   billion cargo and then demanding a ransom for  it as a consequence of those thoughts the exact   shipping date will be held a close secret sure  the chances may be pretty remote but when you are   on the final leg of a two-decade journey you want  to cover all contingencies i guess so yes quite a   busy week of space updates just remember as well  that we are huge supporters of the transition to   electric vehicles 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
