SpaceX gets approval for Starship/Super Heavy factory in LA

8:18 am

Capitalism in space: Having abandoned plans to build its Starship/Super Heavy rocket factory at the Port of Los Angeles in 2019, SpaceX has changed its mind and now gotten approval for the factory from the LA City Council.

First announced in March 2018 and abandoned for about a year beginning in March 2019, SpaceX has refreshed plans to build giant rocket parts in a California port, simplifying aspects of the original proposal and relying heavily on the fact that steel is far easier to handle than carbon fiber. Now, the company wants to refurbish and repurpose a number of old abandoned buildings already present at Port of LA Berth 240, effectively replicating a somewhat smaller version of the Starship production facilities SpaceX is in the middle of building in South Texas.

With Los Angeles Harbor Commission and City Council approvals both safely in hand, SpaceX’s Port of LA Starship is now officially a question of “when”, not “if”. When the concept first popped back into the public discourse late last month, it came alongside a report from CNBC reporter Michael Sheetz that SpaceX wanted to start building Starship parts as few as 90 days after it reapproached Port officials.

The speed in which SpaceX is moving here is very typical for the company. Bodes well for real test flights both this year and next.

SpaceX’s next Starship test flight will go almost eight miles high

10:08 am

Capitalism in space: In its licensing request to the FCC SpaceX has revealed that its next Starship test flight, set to take off sometime between March and September of this year, will take off and land in its space facility in Boca Chica, Texas, and go almost eight miles high.

The filing also indicates the test could possibly go as high as twelve miles.

In related news, the company has announced a job fair this week, aimed at hiring people to work on Starship at Boca Chica. Want to help build the first totally reusable rocket? Here’s your chance.

Further explorations at candidate Starship Mars landing site

4:02 pm

Beginning of Possible Glacial Unit near candidate Starship landing sites
Click for full image.

Close-up on exposed lower layer

Cool image time! Even though it appears that SpaceX has completed its first round of images of its candidate landing sites surrounding the Erebus Montes mountains in the Arcadia Planitia plains in the Martian northern lowlands, this does not mean that other planetary scientists are not asking for more images of this region, for their own scientific research.

The photograph on the right, cropped and reduced to post here, was released in the early November image download from the high resolution camera of Mars Reconnaissance Orbiter (MRO). Uncaptioned but dubbed “Beginning of Possible Glacial Unit,” it shows what appears at first glance to be a relatively featureless area south of Erebus Montes, out in the flat plains.

A closer look suggests otherwise. For one, the full image shows darker and lighter areas. The close-up to the right, its location indicated by the white box in the wider image above, also shows several intriguing depressions that appear to be revealing a knobby lower layer. In fact, in the full image it appears that the darker areas are areas where material has covered that knobby lower layer. Where it is bright the ground resembles the floors of these depressions, knobby and complex.

I do not know why they label this the “beginning” of a glacial unit. What I do know is that the research of this region has consistently found evidence of a lot of buried ice. To quote Donna Viola of the University of Arizona noted, “I think you could dig anywhere to get your water ice.” The knobby features to me suggest a surface that is showing signs of sublimation, where the exposed ice is slowly eroding. Think of what happens to a block of ice when you spray warm water on it. As it melts it leaves behind just these kinds of strange formations.

Overview of all MRO images at Starship candidate landing site

The red box in the map on the right shows the location of this photograph relative to the other images taken for SpaceX. The white boxes are the company’s images taken for Starship. The black boxes are the images it obtained in 2017 when it was thinking of sending a Dragon capsule to Mars.

This map does not show all images taken by MRO’s high resolution camera in this area, but the coverage is very scattered, with many gaps. Over time I suspect these gaps will be filled more quickly than other northern plain regions, because the scientists know that SpaceX has an interest in this area. That interest means there is an increased chance that a mission will fly here in the relatively near future, which in turn is going to generate more scientific interest as well.

Update on SpaceX’s plans for Starship

9:20 am

According to FAA regulatory documents, SpaceX has updated its development plan for Starship, including changes in its overall plans for its Boca Chica facility.

The document also lays out a three-phase test program, which it says “would last around 2 to 3 years”:

Phase 1: Tests of ground systems and fueling, a handful of rocket engine test-firings, and several “small hops” of a few centimeters off the ground. The document also includes graphic layouts, like the one above, showing the placement of water tanks, liquid methane and oxygen storage tanks (Starship’s fuels), and other launch pad infrastructure.

Phase 2: Several more “small hops” of Starship, though up to 492 feet (150 meters) in altitude, and later “medium hops” to about 1.9 miles (3 kilometers). Construction of a “Phase 2 Pad” for Starship, shown below, is also described.

Phase 3: A few “large hops” that take Starship up to 62 miles (100 kilometers) above Earth — the unofficial edge of space — with high-altitude “flips,” reentries, and landings.

The first phase is now complete, with the company shifting into Phase 2.

Boca Chica meanwhile is no longer being considered a spaceport facility. Instead, its focus will now be a development site for building Starship and Super Heavy.

SpaceX to launch Super Heavy/Starship from Florida

8:58 am

Capitalism in space: According to a SpaceX environmental report submitted to NASA, the company now plans to launch Super Heavy/Starship missions from Florida, and only Florida.

The report details the work they want to do at launch complex 39A, where they presently launch both Falcon 9s and Falcon Heavies.

The facilities will be able to support up to 24 Starship/Super Heavy launches a year, the company said in the report, with a corresponding decline in Falcon launches from the complex. “Due to the higher lift capability, Starship/Super Heavy could launch more payloads and reduce the overall launch cadence when compared to Falcon 9 and Falcon Heavy,” the report states.

SpaceX ruled out performing Starship/Super Heavy launches from its other two existing launch sites, Space Launch Complex 40 at Cape Canaveral and Space Launch Complex 4 at Vandenberg Air Force Base in California. The company ruled out the sites because they would require more modifications and because the Vandenberg site didn’t support trajectories for the “vast majority” of missions.

Falcon Heavy launches especially will vanish once this new rocket is operational, as it will be cheaper to use and have greater capabilities, should it succeed in being everything SpaceX hopes it to be.

SpaceX seeking more investment capital

9:09 am

Capitalism in space: SpaceX has begun its third round of private fund-raising this year, this time seeking more than $300 million.

The latest round, filed on Monday, seeks to raise $314.2 million at a price of $214 a share, according to a document seen by CNBC. The new equity would bring SpaceX’s total 2019 fundraising to $1.33 billion once completed.

The block of this new round appears to already be funded from the Ontario Teachers’ Pension Plan.

Super Heavy/Starship construction now in SpaceX facilities in Texas and Florida

7:47 am

Capitalism in space: Even as it prepares for more Starhopper vertical test flights next month, SpaceX has now initiated Super Heavy/Starship construction in its facilities in both Boca Chica, Texas, and Cape Canaveral, Florida.

SpaceX is working a dual test flow for its new Super Heavy and Starship systems, with construction ongoing in Florida while Starhopper prepares to restart test operations in Texas. Two orbital Starship prototypes are now in staggered stages of production while the first Super Heavy booster is set to begin construction in the next three months. However, the focus will soon return to Starhopper, as it prepares for an incremental series of untethered test hops.

Earlier this month it came to light that SpaceX crews at Cocoa Beach in Florida were starting to assemble a second orbital Starship prototype vehicle, similar to the first of such articles that are currently located at the company’s launch and testing facility in Boca Chica, Texas.

According to SpaceX CEO Elon Musk, these two builds were going to be the center of a cooperative/competitive effort between the two sites and their respective team members, in which they would share insights and lessons learned during development – although they were not required to put them to use.

There is another aspect to this that must be emphasized. Super Heavy and Starship are not rockets as we have come to think of them. They are the names for a class of vehicle, each of which is intended to fly many times. SpaceX is therefore not building the first version of a throwaway rocket, but a ship it will use over and over. Because of this, they are not going to be building many of these ships, as you would with an expendable rocket. Instead, they are going to build only a handful, like a ship company that builds luxury ocean liners.

Building two ships simultaneously thus allows them to hone the engineering more quickly and efficiently. It also means that when they are done, SpaceX will have two giant space liners for getting people and cargo into orbit, literally a small fleet that will give them redundancy and make quick flight turnarounds possible.

SpaceX raises more than a billion in investment capital

10:28 am

Capitalism in space: SpaceX announced this week that it has raised more than a billion dollars in investment capital.

The launch provider turned satellite operator raised $486.2 million in one round, and $535.7 million in another, the company said in May 24 filings to the U.S. Securities and Exchange Commission.

The filings show SpaceX sold all but $18.8 million of the shares available between the two rounds. The company raised $1.022 billion in total.

It appears the money will be used to finance the construction of both Super Heavy/Starship and their Starlink satellite constellation. The article also notes that SpaceX generated $2 billion in revenues last year. All told, the company seems to be in very healthy shape financially.

Update of Starhopper testing in Texas

8:43 am

Link here. Nothing spectacular yet, just steady and relatively quick developments.

I did find one aspect of these events a little disturbing:

In quick order, residents of Boca Chica Village were notified via mail of imminent tests and road closures that would occur as early as this week, the week of 18 March.

The notice to residents revealed that a security checkpoint would be set up on the road leading to Boca Chica Village and that residents would have to show proof of residence in order to gain access to their homes; any passengers in those vehicles would also have to show proof of residence.

This indicates that no guests will be allowed past the security checkpoint during the coming flight test operations of Starhopper.

A hard checkpoint beyond which no access to Boca Chica Beach will be granted will be further down the road.

By what right do the authorities have the power to prevent American citizens from bringing guests to their homes? None. If I lived in this development I would fight this, hard.

First SpaceX Starship Hopper tests this week?

8:44 am

Capitalism in space: According to this news story on Sunday, SpaceX could attempt its first Starship Hopper tests this week.

A sheriff hand-delivered road closure notices to residents on Friday, according to a local resident. The document warned locals that SpaceX will “conduct testing” as soon as Monday, March 18.

The article also cites a flurry of tweets about the hopper that Elon Musk made on Sunday. Unfortunately, Musk’s tweets do not say anything about tests this week.

Regardless, it appears that SpaceX might actually be close to beating the schedule it announced for these tests back in November, when Musk said they were aiming for tests in June. If so, this would be a remarkable achievement, one that is almost unheard of in the aerospace launch industry.

SpaceX about to install engines on Starship hopper

9:26 am

Capitalism in space: Late last week SpaceX officials revealed that they are about to install the first two Raptor engines on their Starship hopper prototype being assembled at the Texas spaceport.

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 will conduct checkouts of the newly installed ground systems and perform a short static fire test in the days ahead,” he said. “Although the prototype is designed to perform sub-orbital flights, or hops, powered by the SpaceX Raptor engine, the vehicle will be tethered during initial testing and hops will not be visible from offsite. SpaceX will establish a safety zone perimeter in coordination with local enforcement and signage will be in place to alert the community prior to the testing.” – James Gleeson, March 8th, SpaceX

It is not clear when these first hopper tests will occur, but based on the pace that SpaceX is setting, it should not be too far into the future. Before that however they will likely need to first do some static fire tests, on the ground.

SpaceX’s new Raptor engine: The world’s most powerful?

10:19 am

According to a tweet by Elon Musk, SpaceX’s new Raptor rocket engine has achieved during testing a chamber pressure that exceeds that of Russia’s RD-180 engine, which for decades has held the record.

First and foremost, it’s far too early to actually crown Raptor as the new official record-holder for combustion chamber pressure. RD-180 has been reliably flying on ULA’s Atlas V rocket with chamber pressures as high ~257.5 bar (3735 psi) since the year 2000, while Raptor has been performing subscale integrated testing for roughly two years and full-scale integrated testing for less than seven days. As such, the fact that full-scale Raptor has achieved ~269 bar (3900 psi) is an almost unbelievably impressive achievement but probably shouldn’t be used to jump to any conclusions just yet.

Thanks to the 10-20% performance boost supercool liquid methane and oxygen will bring Raptor, currently stuck using propellant just barely cold enough to remain liquid, the engine performing tests could already be made to reach its design specification of 300+ bar (4350+ psi), although Musk cautioned that he wasn’t sure Raptor would be able to survive that power in its current iteration. Nevertheless, 250 bar is apparently more than enough to operate Starship and its Super Heavy booster during most regimes of flight, although maximum thrust (and thus max chamber pressures) is probably desirable for the first minute or so after launch when gravity losses are most significant. [emphasis in original]

If the Raptor meets these goals, it will make most of Musk’s dreams for Startship and Super Heavy very possible.

SpaceX test fires next generation rocket engine

9:16 am

Capitalism in space: This week Elon Musk tweeted pictures of the first static test firing of the first flight Raptor engine, to be used on SpaceX’s next generation rocket, the Super Heavy first stage and the Starship upper stage.

The billionaire entrepreneur also tweeted out several videos of the 3-second test, which took place at the company’s development facility in McGregor, Texas.

Starship is the 100-passenger stainless-steel vehicle SpaceX is building to take people and cargo to Mars and other distant destinations. Starship will launch atop a giant rocket SpaceX calls Super Heavy. Both of these vehicles will be reusable and Raptor-powered. Starship will sport seven of the new engines, and Super Heavy will use 31 Raptors to get off the ground.

A “hopper” prototype that SpaceX will use to test the Starship design on short flights within Earth’s atmosphere will have three Raptor engines. This hopper will debut soon, Musk has said — perhaps within the next month or so, if everything goes according to plan.

This engine appears to be the first built with the intention to actually fly, and is likely going to be used in that “hopper” prototype.

SpaceX shifts some Starship/Super Heavy construction to Texas

9:03 am

Capitalism in space: SpaceX has decided to shift some of the construction of its new Starship/Super Heavy rocket from Los Angeles to its Boca Chica facility in Texas.

In tweets later Jan. 16, Elon Musk, the founder and chief executive of SpaceX, said that development of the vehicle itself, including the Raptor engines that power it, would continue in Hawthorne, while at least the prototype versions of Starship are built in Texas. “We are building the Starship prototypes locally at our launch site in Texas, as their size makes them very difficult to transport,” he said.

A shift to South Texas, industry sources said, could be a way to reduce expenses, given the lower cost of living there versus the Los Angeles area. However, that region of Texas has a much smaller workforce, particularly in aerospace, compared to Southern California.

Meanwhile, I keep hearing from my sources in the industry that SpaceX is facing more serious problems because of the coming decline in the manufacture of large geosynchronous satellites. The smallsat revolution appears to be the cause, and SpaceX’s larger rockets are not ideal for launching these tiny satellites. I am not entirely convinced of this pessimistic conclusion, but if SpaceX is in trouble it will likely be a tragedy for manned spaceflight. The smallsat rockets cannot put people in space. Neither can the gigantic government rockets like SLS. Without innovative companies like SpaceX building and launching large rockets for profit, the development of the large inexpensive rockets needed for human travel will be significantly hampered.

More updates from SpaceX’s Boca Chica launch site

9:16 am

Link here. The article reviews what has been done for the past few months, as well as what has been done most recently. All of this new work appears focused on preparing for test flights of Starship and Super Heavy.

I should note however that I am beginning to sense a little bit of Barnum in this work. The steel-clad Starship Hopper that SpaceX has assembled here is clearly not even close to doing any hopper tests, as it doesn’t appear to have fuel tanks and its engines appear to be mere “placeholders for fit checks.” It looks really really cool, however, and is impossible to hide to the public, so it thus has garnered the company a lot of attention.

SpaceX reveals picture of fully assembled suborbital Starship hopper

9:14 am

Starship Hopper

Capitalism in space: SpaceX has released pictures of the fully assembled suborbital Starship hopper, planned for its first test flights in the coming months. The image on the right is not a simulation, but the real thing.

In tweets by Elon Musk, he also revealed that they hope to have an orbital prototype of Starship built by June, with the Super Heavy booster beginning construction in the spring. More information here.

This is unquestionably an ambitious schedule, but the contrast with the development of SpaceX’s manned Dragon capsule, slowed absurdly by the government shutdown and NASA’s bureaucracy, highlights clearly the fundamental reason why SpaceX refused government money for the development of Super Heavy/Starship. By using private funds, SpaceX is free to proceed at its own pace, which is fast, rather than waiting for permission from the bean-counters sitting in NASA offices who have no real idea how to build anything.

It is likely they will not meet this schedule. It is also likely that they will also get this done in a time frame far faster than anyone expects.

SpaceX completes fit test of two sections of Starship hopper

9:44 am

Capitalism in space: SpaceX has completed a fit test whereby they put the two main sections of their Starship hopper prototype together.

In a burst of activity that should probably be expected at this point but still feels like a complete surprise, SpaceX technicians took a major step towards completing the first Starship hopper prototype by combining the last two remaining sections (aft and nose) scarcely six weeks after assembly began.

SpaceX CEO Elon Musk also took to Twitter late last week to offer additional details and post what appears to be the first official render of Starship’s hopper prototype, which is now closer than ever before to looking like the real deal thanks to the incredible drive of the company’s southernmost employees. With the massive rocket’s rough aeroshell and structure now more or less finalized, Musk’s targeted February/March hop test debut remains ambitious to the extreme but is now arguably far from impossible.

More details about the status of both the Super Heavy and Starship here. As noted in the first link above, SpaceX is moving very quickly, at a pace unheard of in the rocket industry, to get these hopper prototypes ready for test flights. For example, this new effort at Boca Chica in Texas went from a barren spot to a full facility with a giant spacecraft in less than eight weeks.

Musk tweets peek at Starship hopper

8:52 am

Starship test hopper

Capitalism in space: 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.

Groundwork and licensing begins for first test flights of SpaceX’s Starship

9:31 am

Capitalism in space: Even as SpaceX has apparently begun the licensing process with the FAA for its planned hopper tests for its Super Heavy and Starship heavy lift reusable rockets, it is also accelerating work for those flights at its Boca Chica spaceport in Texas.

The applications apparently describe a two-stage testing program divided into low then high altitude flights, “running approximately three times per week.” Meanwhile, at Boca Chica SpaceX has begin building a giant tent as well as other work.

While I doubt they will be able to begin test flights in 2019 as they have announced, it is clear those test flights will happen in the near future.

Musk renames BFR

9:32 am

He must be reading BtB! Elon Musk today revealed new names for the two stages of his Big Falcon Rocket rocket, Super Heavy for the reusable first stage and Starship for the reusable orbiting second stage.

These are much more inspiring and saleable names. They also do not preclude SpaceX from giving each individual Super Heavy and Starship their own names as well, since these names apply to the class of rocket, not the ships themselves.
