SpaceX Starship BN1 (Booster Number 1) Fully Stacked!, SLS Core Stage Hot Fire, Relativity Space
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 huge thank you to squarespace today for their support of this video

off your first purchase of a website or domain you'll find that link in the description below 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
