    Musk tweets peek at Starship hopper
    .
    Elon Musk this week tweeted an image of the Starship test hopper, adding that they hope to begin test flights by March.

    “This test hopper is at full body diameter of 9m / 30 ft, just not full height. Super Heavy will be full height & diameter,” Musk tweeted, indicating that the company will go directly to building a full-scale version of the rocket booster, rather than a truncated test version.

    It seems to me that Musk continues to embarrass all other rocket companies, both private and governmental, with his effective use of current technology to innovate and produce new designs. While everyone else seems locked into building the same old things, his company is using what it knows to try to build something smarter and more efficient.

    SpaceX’s track record suggests that it will do exactly what it is trying to do, even if it likely takes longer than they predict. Others should take heed, or they will all get left behind.

    SpaceX’s Starship prototype proceeds at breakneck pace towards hop tests
    .
    Well illustrated by recent drone photos of SpaceX’s up-and-coming Boca Chica, Texas facilities, dozens of SpaceXers and local contractors have congregated at the company’s Starship prototype work site over the last few weeks, progressing it from an empty tent and a collection of parts to a handful of large assemblies for what appears to be the first full-scale Starship hopper.

    SpaceX’s Starship hopper spotted with trio of dual-bell Raptor engines
    .
    Following a brief ‘hop’ (via crane) off of a concrete build stand, the aft section of SpaceX’s first full-scale Starship hopper (Starhopper?) revealed that SpaceX technicians have already installed what appear to be three real Raptor engines, presumably the first time the propulsion system has ever been mounted to something that might eventually fly.

    SpaceX's Big Falcon Hopper/Starship Hopper at Boca Chica now has the three sections mated:
    https://twitter.com/NASASpaceflight/...887169/photo/1


    Here’s why Elon Musk is tweeting constantly about a stainless-steel starship
    .
    Eleven months ago—just after SpaceX astonished the world by launching and landing its titanic Falcon Heavy rocket while beaming back images of a red Tesla leaving Earth orbit—company founder Elon Musk had already begun to look beyond the moment.

    The Falcon Heavy was a big, capable rocket. But it wasn't large enough to fulfill his aspirations of reaching Mars. Neither did the company have a spacecraft capable of landing there. "They really need to be way bigger than that," Musk said of the Falcon Heavy rocket at the time. Moreover, he noted that the launch in early February 2018 had confirmed the company's ability to model rocket launches on computers. "It gives me a lot of faith for our next architecture. It gives me confidence that BFR is really quite workable."
    ...
    Since December 22, Musk has tweeted about the Starship vehicle more than two dozen times. Among the details that can be gleaned from those tweets:

    • The vehicle's exterior will be made from a stainless-steel alloy that will not buckle and will remain stable on the launchpad even when unpressurized. The strength and weight of "full hard stainless" at cold temperatures is slightly better than carbon fiber, at room temperature it is worse, and at high temperature it is vastly better.
    • The metallic skin of Starship will get too hot for paint, so it will have a stainless mirror finish. It will need much less shielding as a result, and areas that take the brunt of atmospheric entry heating will be activity cooled with residual liquid methane. As a result, "Starship will look like liquid silver."
    • A "radically redesigned" Raptor engine will be ready for test firing early this year. This is the engine that will power both the first stage "Super Heavy" as well as the Starship. For the test hopper, there will be three Raptor engines (there will be seven on the full Starship). Engines currently on the vehicle are essentially mock-ups. The first engine for hopper test flights "is almost finished assembly in California."
    • SpaceX developed a "superalloy" to withstand the incredible pressures inside the Raptor engine and its hot, oxygen-rich gas. "Our superalloy foundry is now almost fully operational. This allows rapid iteration on Raptor."
    • Musk expects the first hopper tests to occur in March or April of this year, sooner than expected. "I will do a full technical presentation of Starship after the test vehicle we're building in Texas flies."
    • Musk believes a single-stage-to-orbit launch from Earth is "pointless." A large booster is needed to escape Earth's gravity well if one wants a decent-sized payload. But the single-stage Starship alone is great for launching from Mars and the moons of the Solar System.

    SpaceX CEO Elon Musk says first orbital Starship prototype will be done by June
    .
    SpaceX CEO Elon Musk says that the company’s first Starship prototype – a low-fidelity hop test vehicle – has finished assembly in South Texas, paving the way towards a series of experimental vertical take-off or landing (VTOL) hop tests that could begin as early as February or March 2019.

    One step beyond the prototype currently rising out of the coastal Texas wetlands, Musk also indicated that the first orbital Starship prototype – essentially the spacecraft’s first full-fidelity test article – could be completed as early as June 2019, a truly extraordinary pace of development for a program as complex and cutting-edge as BFR.

    STARHOPPER RISING

    Barely six weeks after work began on the massive Starship prototype, SpaceX’s Starhopper appears to have grown to its full ~40m (~130 ft) height in South Texas. Following a preliminary fit test on Tuesday, January 8th, workers made a second attempt on Wednesday and completed the final attachment of Starhopper’s upper and lower halves. Intriguingly, no time was wasted spot-welding the halves together after their successful docking, and an additional sheet of stainless steel has been welded over the seam in the hours since then.

    However, what looks like 9m-diameter (~30 ft) steel tank domes are being assembled and welded together....

    SpaceX gearing up for Starship tests at Boca Chica
    .


    At the southern tip of Texas, SpaceX is preparing to begin testing their interplanetary spacecraft. The first Starship test vehicle, dubbed Starhopper, is in advanced stages of construction, and SpaceX facilities at Boca Chica and McGregor are preparing to support a flight test program beginning this year.

    The new South Texas Launch Site was originally intended to be a third launch facility for SpaceX’s Falcon 9 and Falcon Heavy vehicles, in addition to Cape Canaveral, Florida and Vandenberg Air Force Base, California.

    While current plans now focus on the Starship and Super Heavy vehicles, the layout of the launch site appears to be largely unchanged. A building permit reading “operational hopper pad for rocket launches” is posted at the location of the originally proposed launch pad.

    In blow to Los Angeles, SpaceX is moving some Mars spaceship and booster work to Texas
    Jan. 16, 2019
    .
    In a reversal of a deal local officials had touted as a win for Los Angeles tech, SpaceX will no longer build its Mars spaceship and rocket booster system at the Port of Los Angeles. Instead, work to build and test the prototype will be done in south Texas.

    SpaceX said in a statement Wednesday that the decision was made to “streamline operations.”

    In a tweet, Chief Executive Elon Musk said: “Starship & Raptor [engine] development is being done out of our HQ in Hawthorne, CA. We are building the Starship prototypes locally at our launch site in Texas, as their size makes them very difficult to transport.”

    SpaceX to shift Starship work from California to Texas
    .
    WASHINGTON — Less than a week after laying off 10 percent of its employees, SpaceX said Jan. 16 that it plans to shift work on at least prototypes of its next-generation launch system from Los Angeles to Texas.

    In a statement, SpaceX said it was now planning to build prototypes of its Starship vehicle, the upper stage of its next-generation reusable launch system, at its site in South Texas originally designed to serve as a launch site. An initial prototype version of that vehicle has been taking shape in recent weeks at the site in advance of “hopper” tests that could begin in the next one to two months.

    “To streamline operations, SpaceX is developing and will test the Starship test vehicle at our site in South Texas,” company spokesperson Eva Behrend said in an emailed statement. The news was first reported by the Los Angeles Times after a pair of tweets early Jan. 16 from Joe Buscaino, a member of the Los Angeles City Council whose district includes the Port of Los Angeles.

    “While I feel crushed about #SpaceX pulling the #SuperHeavy out of the @PortofLA, I feel confident that other innovators will see the huge value they get in San Pedro,” he wrote. Super Heavy is the name SpaceX recently gave to the lower stage of the overall launch system that previously had the formal name of Big Falcon Rocket, or BFR. The upper stage was renamed Starship.

    SpaceX separates Starship prototype’s nose and tail to install giant propellant tanks
    .
    After a handful of days as an impressive monolith stood along the coastal wetlands of Texas, SpaceX technicians have once again separated the nose and tail sections of the first Starship prototype to allow additional integration and assembly work to continue. The craft’s three Raptors were also removed and stored nearby, shown to be barebones facsimiles standing in for flightworthy hardware that could arrive in the next month or two.

    Up next, three or four propellant tank domes – currently being assembled and welded together on-site – will likely be installed inside the steel hull of the giant Starship prototype’s aft barrel section. Known as bulkheads, the installation of those tank domes will bring SpaceX one step closer to performing hop tests of the simultaneously bizarre, confusing, and beautiful craft.

    Why the Starship is Built of Stainless Steel
    .
    So SpaceX is making a huge rocket out of stainless steel. As far as we know, this marks the first time the material has been used in spacecraft construction since some early, ill-fated attempts during the Atlas program in the late 1950s.

    We know he is doing this because, after weeks of rumors about a tweak to the design, a few days before Christmas Musk revealed that there would be much more than a tweak. The state-of-the-art carbon fiber forming the body of the Starship rocket (formerly known as the BFR, or Big Falcon Rocket, or Big F-other-word Rocket) and its Super Heavy booster would be replaced by 300-series stainless.

    On January 10, Musk tweeted a photograph of a test version of Starship—essentially a prototype that can be used for suborbital VTOL (vertical takeoff and landing) test flights, reaching around 16,400 feet. He is calling these “hops.”

    Since the quasi-unveiling, Musk has briefly answered some direct questions from the curious space-watchers of cyberspace via Twitter. But two weeks before the announcement he sat down with Popular Mechanics editor in chief Ryan D’Agostino at SpaceX headquarters in Hawthorne, California, for an exclusive interview in which he discussed, in great detail, the thinking behind the change. He talked about a lot more than that—we’ll be bringing you more soon. For now, here’s what he said about the big change.

    “Will take a few weeks to repair,” Musk said in a tweet.

    The fairing is the top portion of the rocket, which on normal launches would hold the payload. The bottom portion of the rocket was undamaged, Musk said.

    SpaceX CEO Elon Musk explains Starship’s ‘transpiring’ steel heat shield in Q&A
    .


    Speaking in a late-December 2018 interview with Popular Mechanics’ editor-in-chief, SpaceX CEO Elon Musk shared considerable insight into the thought processes that ultimately led him to – in his own words – “convince” his team that the company’s BFR rocket (now Starship and Super Heavy) should pivot from an advanced composite structure to a relatively common form of stainless steel.

    Aside from steel’s relative ease of manipulation and affordability, Musk delved into the technical solution he arrived at for an advanced, ultra-reusable heat shield for Starship – build it out of steel and use water (or liquid methane) to wick reentry heat away.
    .

    SpaceX workers cap Starship with tank dome as Raptor arrivals and hop tests near
    .
    SpaceX employees and local contractors continue to outfit the aft section of the first full-scale BFR prototype with a variety of important components, recently culminating in the installation of the Starship hopper’s top propellant tank dome,

    Critical to the arrival and installation of its Raptor engines and the craft’s first hop tests, this work continues despite the premature demise of Starhopper’s apparently fragile nose cone (fairing), toppled on January 22nd when fairly mild winds of around 50 mph (80 km/h) encountered the shoddy rigging meant to keep the huge but lightweight hardware on its concrete stand.

    SpaceX CEO Elon Musk reveals photos of Starship’s first completed Raptor engine
    .


    Shortly after Teslarati reported that the first operationalized Raptor had shipped to McGregor, Texas for its first full-scale static fire tests, SpaceX CEO Elon Musk took to Twitter to post the first official photos of the “radically redesigned” engine preparing for its critical debut test fire in Texas.

    Designed with extreme reliability, efficiency, and reusability in mind, the Raptor seen in Musk’s photos is rated for just shy of 2.5 times the thrust of Merlin 1D at 200 tons (450,000 lbf) and has been commonized across both stages of BFR (Starship and Super Heavy) to spread out development costs and speed up the next-generation rocket’s orbital launch debut.

    SpaceX sends “radically redesigned” Starship engine to Texas for hot-fire tests
    .
    SpaceX has shipped one of the first of a group of Starship engines known as Raptor, described last month by CEO Elon Musk as “radically redesigned”. A culmination of more than 24 months of prototype testing, the first flight-worthy Raptor could be ignited for the first time as early as February.

    According to Musk, three of these redesigned Raptors will power the first full-scale BFR prototype, a Starship (upper stage) test article meant to conduct relatively low-altitude, low-velocity hop tests over the southern tip of Texas. Those tests could also begin next month, although a debut sometime in March or April is increasingly likely.

    SpaceX CEO Elon Musk arrives in Texas for milestone Starship engine test
    .
    On Saturday evening, SpaceX CEO Elon Musk landed in Waco, Texas – perhaps along with additional SpaceX propulsion engineers – for the critical static fire debut of the first “radically redesigned” Raptor engine, built to power BFR’s Starship upper stage and Super Heavy booster.

    If the first operationalized Raptor’s static fire tests go well, there are several possible routes the test program could take, all of which will end up with this engine and several others being tested and ultimately installed on the Starship hopper (Starhopper) prototype under construction roughly 500 miles (800 km) south of SpaceX’s Raptor test cell.

    SpaceX’s first redesigned Raptor static fire paves the way for Starship’s hop test debut
    .
    After years of development, multiple prototypes constructed, and more than 1200 seconds of cumulative static fire testing at durations longer than what is needed to land on Mars, SpaceX propulsion engineers and technicians have successfully built and static-fired the first flight-worthy Raptor for the first time ever.

    This is an incredibly important step towards BFR (Starship/Super Heavy) launch operations and is even more directly encouraging for the first integrated hop tests of SpaceX’s Starship prototype (unofficially deemed Starhopper), which could very well be the next host of the pathfinder Raptor engine pictured below.

    SpaceX’s Starship prototype is looking increasingly rocket-like as hop test pad expands
    .
    As SpaceX’s South Texas operations continue full steam ahead in pursuit of the first integrated hop tests of a full-scale Starship prototype, the company’s Starhopper and its complementary launch/hop pad are dramatically and visibly evolving on a daily basis.

    This week’s progress has been signified by the installation of familiar rocket hardware on the Ship and a burst of construction – centered around pipelaying, plumbing, foundation work, and berm-building – at its pad. Just a few hundred miles north of Boca Chica, SpaceX’s team of propulsion engineers and technicians reached their own dramatic milestone, conducting the first static fire of a finalized version of the Raptor engine set to power Starship and Super Heavy (formerly BFR).

    https://www.teslarati.com/spacex-sta...pad-expansion/


    Raptor fired at power level needed for Starship, Super Heavy
    .
    SpaceX’s first Raptor flight engine performed another test fire, this time increasing its force and chamber pressure to required levels for the company’s giant next-generation rocket.

    Raptor was moved to a test stand at SpaceX’s McGregor, Texas, facility late last month and fired for the first time on the evening of Feb. 3, 2019. Now, less than a week later, company founder and CEO Elon Musk tweeted that another test took place.

    “Raptor just achieved power level needed for Starship [and] Super Heavy,” Musk tweeted just after 3 a.m. EST (08:00 GMT) Feb. 7.

    Musk did not say how long the test was or if it was at full power. The Feb. 3 burn was only about two seconds and at about 60 percent power. However, he said the latter test reached a chamber pressure of 257 bar, or about 3,700 pounds per square inch, and an estimated force of about 172 metric tons with “warm propellant.”

    The Starship and Super Heavy design requires at least 170 metric tons, Musk said, and added that with deep cryogenic propellant, another 10-20 percent performance could be achieved.

    For comparison, each of the nine kerosene and liquid oxygen-consuming Merlin 1D engines used at the base of the Falcon 9 rocket’s first stage produce about 86 metric tons of thrust.

    https://www.spaceflightinsider.com/o...p-super-heavy/


    SpaceX’s Starship engine hits twice the thrust of Merlin just days after test debut
    .
    SpaceX CEO Elon Musk says that the company’s Raptor engine – static-fired for the first time at full scale barely four days ago – has been successfully fired at roughly 90% max thrust, briefly producing more than twice the force of one of Falcon 9’s Merlin 1D engines.

    Relying on SpaceX’s McGregor, Texas test facilities for its testing, Raptor was being fed with propellant significantly warmer than the supercool liquid methane and oxygen it was nominally designed to use. Even still, the 172 tons (380,000 lbf) of thrust it produced is apparently already enough to satisfy the design requirements of Starship and Super Heavy, and Musk believes that with properly cooled propellant, the same Raptor engine could produce more than 200 tons of thrust at full throttle.

    Design requires at least 170 metric tons of force. Engine reached 172 mT & 257 bar chamber pressure with warm propellant, which means 10% to 20% more with deep cryo.

    — Elon Musk (@elonmusk) February 7, 2019

    Following a presumably successful inaugural test fire on February 3rd, SpaceX added some rare technical insight to Raptor’s performance, stating that it had “hit 170 bar [in the combustion chamber] and [produced] ~116 metric tons” of thrust while operating at “60% power.” Suggesting that Raptor has already met certain design expectations less than 100 hours into integrated hot-fire testing, Musk’s technical update indicates that the engine may already be operating (more or less) as expected at something approximating full throttle.

    Even for SpaceX, the speed of progression demonstrated thus far by SpaceX’s Raptor propulsion team is almost unbelievable in the context of just how utterly different the engine is from anything SpaceX is familiar with, let alone the field of liquid rocket propulsion as a whole. As long as the company is not consciously taking major risks or cutting corners with such an expedited test program, it’s safe to conclude that the data Raptor’s has produced with its first several tests is extremely encouraging, verifying that the engine is likely behaving almost exactly as expected from an engineering perspective. As a result, the engine’s testing jumped from 60% power to the equivalent of full-throttle (with off-nominal propellant temperatures) in four days.

    SpaceX’s Starship engine breaks Russian rocketry record held for two decades


    SpaceX CEO Elon Musk says the company’s Raptor engine, meant to power Starship and Super Heavy, has surpassed a rocketry record held by Russian scientists and engineers for more than two decades.

    Known as combustion chamber pressure, Raptor has reportedly surpassed a modern Russian engine known as the RD-180, reaching forces equivalent to one Tesla Model 3 balanced on every square inch of Raptor’s combustion chamber, the hardware directly adjacent to a rocket engine’s bell-shaped nozzle.

    With a focus on ease of scalable 3D-printing and inhabitants’ quality of life, as well as the use of modular imported goods like windows and airlocks, MARSHA lends itself impeccably well to SpaceX’s goal of developing a sustainable human presence on Mars as quickly, safely, and affordably as possible with the support of its Starship/Super Heavy launch vehicle.

    SpaceX prepares to eat its young
    by Dick Eagleson - October 2, 2017
    .
    Where I was seated, it was 9:40 pm Pacific time Thursday when Elon Musk began his latest presentation about “Becoming a Multi-Planetary Species” at the International Astronautical Conference in Adelaide, Australia. Having now subsequently read several reports about the event in the press, here are my thoughts on The Meaning Of It All. I've done my best not to repeat what others have said elsewhere.

    The most surprising thing, to me, was the flat declaration by Musk that SpaceX's entire current—and imminent—product line is now on track to be sunsetted in an orderly fashion over the next few years. The only comparable example of corporate autophagy I can recall was Apple's move from its established Apple II line to mice, windows, and icons with the Lisa and Macintosh.

    SpaceX job posts confirm Starship’s Super Heavy booster will be built in Texas
    .


    A duo of SpaceX job postings at the company’s South Texas facilities have confirmed that both Starship and Super Heavy “flight article” vehicles will initially be fabricated and assembled on-site in Boca Chica, also implying that the rocket’s first orbital launch attempts will occur in the same vicinity.

    Construction of the first massive Super Heavy booster could begin in Boca Chica within the next several months, presumably progressing in a similar fashion to Starship’s full-scale hopper prototype. According to CEO Elon Musk, Starhopper hop tests and Super Heavy construction could begin – respectively – as early as March and April 2019, perhaps just one or two months from now.

    SpaceX CEO Elon Musk says that BFR could cost less to build than Falcon 9
    .
    SpaceX CEO Elon Musk believes that there may be a path for the company to ultimately build the massive Starship spacecraft and Super Heavy booster (formerly BFR) for less than Falcon 9/Falcon Heavy, a rocket 3-9 times smaller than BFR.

    While it certainly ranks high on the list of wild and wacky things the CEO has said over the years, there may be a few ways – albeit with healthy qualifications – that Starship/Super Heavy production costs could ultimately compare favorably with SpaceX’s Falcon family of launch vehicles. Nevertheless, there are at least as many ways in which the next-gen rocket can (or should) never be able to beat the production cost of what is effectively a far simpler rocket.
    .
    This will sound implausible, but I think there’s a path to build Starship / Super Heavy for less than Falcon 9

    SpaceX’s first Starship engine suffers “expected” damage during Raptor test fire
    .
    SpaceX CEO Elon Musk says that the first full-scale Starship engine to be tested has already been pushed to the point of damage less than three weeks after the campaign began, setting the stage for the second full-scale Raptor to take over in the near future.

    According to Musk, while most of the damaged pathfinder Raptor’s components should still be easily reusable, the assembly of the second finalized engine is “almost done” and that Raptor will take over near-term testing rather than waiting for repairs to the first engine. This is undoubtedly an extraordinarily aggressive test program, particularly for such a new and cutting-edge rocket propulsion system, but these latest developments are ultimately far more encouraging than they are concerning.

    SpaceX Starship Hopper Moving to Boca Chica Launch Pad - Livestream
    https://www.youtube.com/watch?v=qIFpLblpC-E


    SpaceX’s Starship prototype moved to launch pad on new rocket transporter
    .
    Over the last two or so weeks, SpaceX engineers and technicians have continued to make progress on the company’s first full-scale Starship prototype, intended to support experimental suborbital hop tests as early as March or April.

    That work reached a peak on March 8th when the massive Starhopper was transported from build site to launch pad on a brand new transporter that was delivered and assembled barely 48 hours prior. Ahead of the suborbital prototype’s move, work has been ongoing to construct a replacement fairing for the partial-fidelity vehicle, although there is a chance that the new BFR-related stainless steel sections being assembled could be the start of the first orbital Starship prototype.

    SpaceX’s Elon Musk says Raptor will be installed on Starship prototype this week
    .
    Speaking on Friday, March 8th, SpaceX CEO Elon Musk announced that the company’s second completed Raptor engine was already “on [its] way to [Star]hopper” to – nominally – be installed on the prototype vehicle as early as the week of March 11th (this week).

    According to an official SpaceX statement, once Raptor is installed on Starhopper, the integrated vehicle will perform a combination of ground systems testing, propellant loading, static fire tests, and low-altitude hover demonstrations to prove out the brand new vehicle, engine, and facilities. Prior to the final months of 2018, the build site, launch pad, and prototype Starship now preparing for imminent hop tests were little more than empty dirt lots on the southern tip of the Texas coast.

    SpaceX begins static Starhopper tests as Raptor engine arrives on schedule
    .
    SpaceX has officially begun static ground testing of Starhopper, a full-scale pathfinder Starship prototype meant to support an early series of Raptor-powered hop tests at SpaceX’s South Texas launch site. Simultaneously, the second completed Raptor engine arrived at the site on Monday, March 11th, confirming CEO Elon Musk’s March 8th tweets about the delivery.

    While reasonably routine for any rocket test program, the first tanking test of Starhopper effectively marks the first time that SpaceX has begun tests with a more or less fully integrated Starship (previously BFS). Likely performed with liquid nitrogen instead of liquid oxygen/methane, the first few tanking tests will be used to determine the quality of the prototype’s stainless steel tanks – built en plein air in a fairly unorthodox fashion – and test whether they are functional pressure vessels without risking immediate and total destruction. If successful, SpaceX will proceed into Raptor integration and integrated static-fire tests before preparing for tethered hover tests, perhaps as early as later this month.

    SpaceX goes all-in on steel Starship, scraps expensive carbon fiber BFR tooling
    .
    In a wholly unforeseen turn of events, SpaceX has taken the extraordinary step of permanently scrapping both its Port of Los Angeles-based BFR development tent and what seem to be the majority of what it contained, irreparably destroying custom-built tooling meant to support the fabrication of carbon composite BFR spaceships and boosters.

    Likely worth anywhere from several to tens of millions of dollars (USD), SpaceX’s advanced BFR production tools were procured from industry-expert Ascent Aerospace sometime in 2017 before being officially delivered to the rocket company’s newly-erected Port of LA tent around April 2018. Situated at the port specifically due to logistical concerns about the high cost of transporting 9m/30ft-diameter objects from SpaceX’s main Hawthorne facilities to a barge for transport east, the company has decided to unequivocally destroy its aerospace-grade composite tooling less than 12 months after accepting delivery. Put simply, this is the best evidence yet that SpaceX – willing or not – has gone all-in on build Starship and Super Heavy out of stainless steel less than six months after CEO Elon Musk began to hint at the program’s utterly radical pivot.
