SpaceX wins first new launch contract in 2020

Points of Information

Capitalism in space:The Egyptian communcications satellite company Nilsat this week announced that it has awarded SpaceX the launch contract for its next satellite.

This was SpaceX’s first contract award in 2020.

The article goes into great detail about SpaceX’s present launch manifest, which according to the company has contracts for future launches equaling $12 billion.

Based on public info, SpaceX has roughly 55 customer launches on its manifest. The company also intends to launch as many as 24 dedicated Starlink missions this year and will need at least another 40-50 on top of that to complete the first phase of the broadband internet satellite constellation (~4400 spacecraft). Meanwhile, SpaceX has won at least nine separate launch contracts – two Falcon Heavy missions and seven Falcon 9s – in the last 18 months, but has launched 22 customer payloads in the same period.

In fewer words, SpaceX is effectively launching its existing commercial missions much faster than it’s receiving new contracts. In 2019, for example, the company launched only 11 commercial missions – 13 total including two internal 60-satellite Starlink launches. SpaceX launched 21 times in 2018, a record the company initially hoped to equal or even beat last year, but – for the first time ever – the launch company was consistently ready before its customers were.

It appears SpaceX intends to pick up any slack in launch contracts with Starlink satellite launches, which once in orbit are another major income source for the company.

Overall, it seems to me that SpaceX is quite awash with capital, which reinforces their decision to not take government money to develop Starship. Using their own capital they are free to build as they see fit, with no one from the government who knows less than they do looking over their shoulder and kibitzing.

SpaceX is shifting all Starship design work to Boca Chica

Points of Information

Capitalism in space: In a change in plans, SpaceX is no longer having two competitng Starship design teams working in both Florida and Boca Chica, and is now in the process of moving all hardware to Boca Chica.

Though the article is mostly about SpaceX’s fleet of ships, it notes this change in Starship development plans.

Further explorations at candidate Starship Mars landing site

Essays And Commentaries

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.

Explosion during Starship tank tests

Points of Information

During tests today of SpaceX’s Starship Mk1 test prototype there was a sudden explosion, damaging the spacecraft. Below is a clip from today’s live stream showing the explosion.

They had been doing a variety of tank and venting tests for the past day. (The link includes a video showing the first pressurization test yesterday.)

The Mk1 (Mark 1) was being built with an initial hoped-for schedule targeting the first orbital flights by next year. No one took that seriously, and today’s incident reinforces that skepticism. At the same time, SpaceX has routinely recovered very quickly from its engineering test failures, treating them as opportunities for improving their designs. It is for this reason that most knowledgeable observers of the company also expected any delays to that target schedule to never be very extended.

Moreover, earlier this week SpaceX revealed that it had already decided not to fly this version and proceed to their next version. A Mk2 version is being built in Florida, so in Boca Chica they will proceed to the Mk3, with the goal to get to build toward the final operational version, what Musk labeled the Mk5. Based on past SpaceX policy, however, expect them to begin commercial flights with the earlier versions as they upgrade to the Mk5.

UPDATE: It appears the explosion occurred during a maximum pressurization test, which means they now have data telling them the limits of their tank design.

SpaceX completes 1st round of Starship’s Mars landing site images

Essays And Commentaries

All locations photographed of the candidate landing region for SpaceX's planned Mars missions

On August 28, 2019 I broke the story that SpaceX is beginning to obtain images of candidate Starship landing sites from Mars Reconnaissance Orbiter (MRO).

It now appears that SpaceX has completed its first round of Starship requests from MRO. In the image releases from Mars Reconnaissance Orbiter (MRO) since September, only three new Starship locations were taken, and all three were the unreleased candidate sites I noted in my September 16, 2019 update.

Below is the full list of all of the Starship images, their locations indicated on the map above by the numbered white boxes:

With the release of these last photographs, the initial list of proposed images of candidate Starship landing sites on Mars has apparently been completed. No additional images at any other locations appear to have been suggested. The MRO science team has taken stereo images of each one of the nine locations, eight of which were in Amazonis Planitia, and one in Phlega Montes.

This however is not the first round of pictures requested by SpaceX of the Arcadia Planitia region in connection with the company’s desire to land spacecraft on Mars.

Starship manned lunar landings by 2022?

Points of Information

Capitalism in space: According to SpaceX’s CEO Gwynne Shotwell at a conference on October 25, the company is targeting the first unmanned cargo landing of Starship on the Moon by 2021, with manned missions shortly thereafter.

Shotwell, speaking at Baron Fund’s annual investment conference at the Metropolitan Opera House on Friday, gave an update on SpaceX’s goals for Starship. “We want Starship in orbit next year; we want to land it on the moon before 2022 with cargo and with people shortly thereafter,” Shotwell said.

However, much like Musk in his presentation last month, Shotwell hedged her estimate, saying that “every time I make a prediction about schedule I turn myself into a liar.”

If they even come close to doing this they will certainly make NASA’s SLS rocket look ridiculous. They began serious development of Starship in early 2019. Even if development takes twice as long as Shotwell’s prediction, they will be landing on the Moon in about six years, in 2025. SLS has been in development since 2004, and its total cost once launched is expected to be more than $25 billion, a cost that does not include an extra $1.6 billion NASA has said it needs to land on the Moon by 2024 and that Congress has so far refused to appropriate.

SpaceX meanwhile has raised $1.3 billion, from private sources, to build Starship.

SpaceX extends Boca Chica purchase deadline, will do new appraisals

Points of Information

SpaceX has agreed to do new appraisals on the private homesites in Boca Chica that it wishes to purchase, while also agreeing to extend the deadline for owners to accept their offer.

It appears that Musk invited the owners to his Starship presentation on September 28, and then met with some of them afterward to discuss the situation face to face.

Musk met with seven villagers following the presentation, though others … gave up waiting for him to show.

Cheryl Stevens, who owns a house down the street from the Heatons, did stick around. The meeting was “sort of testy” at first, as the owners confronted Musk with their concerns after waiting a long time, though the mood eventually lightened, she said. “We all had things we wanted to say,” Stevens said. “He was good about listening to what we said, then referring to what we said. … I left there feeling OK. Overall it was fairly cordial, just testy at the beginning. At least we felt like we were heard.”

At the same time, she said, “I’m not interested in giving my house away.”

This is the kind of thing that Musk does very well. Rather than stay in his ivory tower, as most modern big corporate heads, he talks with people directly. I expect SpaceX will end up offering these people deals where they can buy homes relatively comparable to what they have now, in a similar location. This will engender good will, and good press for the company.

Musk shows off Starship

Points of Information

Capitalism in space: In a tweet on September 22 Elon Musk gave an update on the status of its Starship rocket.

His tweet provided a picture of crews attaching “rear moving fins” the what they are now calling Starship Mk1.

The photo showed the stainless steel hull of the rocket as SpaceX attached two large fins to the base. Starship is a massive, next-generation vehicle that Musk’s company is building to send cargo and as many as 100 people to the moon and Mars.

Musk is expected to make a major speech on September 28 on Starship’s status.

More potential Starship landing sites on Mars

Essays And Commentaries

Starship landing sites

On August 28, 2019 I broke the story that SpaceX is beginning to obtain images of candidate Starship landing sites from Mars Reconnaissance Orbiter (MRO).

Many news sources, skilled in their ability to rewrite press releases, saw my article and immediately posted stories essentially repeating what I had found, including my geological reasoning. Some did some more digging and, because they came out a few days later they were able to take advantage of the next MRO team image release, issued on August 30th, to find a few more candidate site images.

Those additional images included the remaining stereo images for all the images in my August post, indicated by the white boxes in the overview map above. They also included two new locations, indicated by the black boxes. One was of one more location in the easternmost hills of Erebus Montes. The other was a stereo pair for one entirely different landing location, farther to the west in the mountains dubbed Phlegra Montes, a location that SpaceX had previously been considering, but until this image had not been included in its MRO image requests.

The grey boxes in the map above show the approximate locations of images not yet officially released by MRO. Though unreleased, their existence is still public knowledge, as they are listed as already acquired images in the HiWish database. Below are links to the three upcoming new images (the second stereo images for locations #1 and #2 are not included)

Both the Phlega Montes location and #3 above appear to be looking at soft slushy material that might have a lot of water just below the surface.

Update on SpaceX’s plans for Starship

Points of Information

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.

FAA required SpaceX to up its insurance for Starhopper test

Points of Information

The FAA’s office that regulates commercial space required SpaceX to increase its insurance coverage for this week’s Starhopper test to $100 million, thirty three times higher than their coverage for the previous Starhopper hops.

Lots of information at the link, though in summary it all makes perfect sense.

There are a number of likely reasons the federal regulator required SpaceX to boost its insurance coverage, says George Nield, a former FAA associate administrator who led its Office of Commercial Space Transportation (OCST) for more than a decade.

One is that Tuesday’s launch took Starhopper hundreds of feet higher than in July; during the prior flight, SpaceX’s vehicle only went about 60 feet (18 meters) up before landing. “The higher you want to go, the more propellant you’re going to have to load, and the more propellant you load, the bigger the boom if it were to explode,” Nield told Business Insider prior to Tuesday’s launch.

More importantly, their Boca Chica launch site is only a mile and a half from a small village of about twenty people, much closer than any other launchpad in the world. How SpaceX will manage this issue should they wish to test fly their fullscale Starship prototype from this site I really do not know. It could be that they won’t, and will confine all test flights to Kennedy, where they are also building a second Starship prototype.

SpaceX begins hunt for Starship landing sites on Mars

Essays And Commentaries

Candidate landing sites for SpaceX's Starship

In the August image release from the high resolution camera of Mars Reconnaissance Orbiter (MRO) were five images whose title immediately caught my interest:

The overview map on the right shows the location on Mars for these five photographs. The second and third images are of the same location, taken to produce a stereo pair.

To put it mildly, it is most intriguing to discover that SpaceX is beginning to research a place where it can land Starship on Mars. I immediately emailed Nathan Williams, the JPL scientist who requested these images from SpaceX, but he was bound by a non-disclosure agreement with SpaceX and could not comment. I have since tried to get some information directly from SpaceX but so far the company has not responded. A 2017 news story had indicated the company’s interest in this Mars’ location, but gave no details either.

Based on what we now know of Mars, however, it is possible to figure out why they favor this location, on the border between the two large northern lowland plains Arcadia and Amazonis Planitia.

SpaceX to launch Super Heavy/Starship from Florida

Points of Information

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.

New NASA development contracts include refueling work by SpaceX

Points of Information

Capitalism in space: Yesterday NASA announced a bunch of partnership agreements with thirteen companies, where those companies will get NASA assistance at no cost to help them develop new engineering that would aid future solar system exploration.

The partnerships covered everything from helping small companies develop new space electronics, heat shields, and new types of thrusters to helping Blue Origin develop the technology for for landing on the Moon.

An article at Ars Technica today about this NASA announcement focused specifically on the SpaceX deal, mainly for its important political implications.

The partnership will have two different NASA agencies helping SpaceX develop the refueling technology it needs for Starship to reach Mars. The key is that this deal has NASA openly supporting technologies that are in direct competition with its own SLS rocket. When such research work was proposed back in 2010, it was opposed quite strongly by past agency officials as well as powerful politicians in Congress, for exactly that reason.

It was a contentious time in space policy, as the White House was pushing for more funding for new space companies—and new space ideas such as fuel-storage depots—while Congress wanted to keep NASA in the rocket-building business.

Eventually, Congress got the upper hand, putting NASA on track to build the large SLS rocket at a development cost of more than $2 billion a year. The rocket program mostly benefited the Alabama space center and was championed by Alabama State Senator Richard Shelby. The potential of in-space fuel storage and transfer threatened the SLS rocket because it would allow NASA to do some exploration missions with smaller and cheaper rockets. As one source explained at the time, “Senator Shelby called NASA and said if he hears one more word about propellant depots he’s going to cancel the Space Technology program.”

The line from other NASA officials was that as a technology, propellant depots were not ready for prime time. In 2011, former NASA Administrator Mike Griffin and current Executive Secretary of the National Space Council Scott Pace—both SLS advocates—wrote a withering criticism of the technology for Space News.

Now however the Trump administration is helping SpaceX develop refueling for Starship, which if successful will help make SLS irrelevant. This is more evidence that the Trump administration is laying the political groundwork that will allow it to shut SLS down, actions that were impossible in the political culture of Washington only two years ago.

This quote in the article is probably the most startling of all:

“Administrator Bridenstine is clearly executing on President’s Trump’s guidance to increase commercial public-private-partnerships at NASA,” Miller, now chief executive of UbiquitiLink, told Ars. “The game-changing technology that NASA has discovered is capitalism. This program proves NASA leadership has figured out the future is reusability mixed with commercial public-private-partnerships.” [emphasis mine]

Imagine that. An American government agency has learned that capitalism is the way to go. Will wonders never cease?

Update: See this related Ars Technica article: The SLS rocket may have curbed development of on-orbit refueling for a decade (Hat tip reader Calvin Dodge.)

Fire at SpaceX Starhopper facility in Florida

Points of Information

A fire in SpaceX’s Florida facility yesterday, where it is building a Starship prototype, caused between $50,000 to $100,000 damages.

City spokesperson Yvonne Martinez confirmed a small fire broke out at the facility on Cidco Road around noon and that the Cocoa Fire Department was able to quickly extinguish it. She said crews suspected an electrical fault as the source of the fire.

“This afternoon, a small fire occurred at a SpaceX facility in Cocoa,” SpaceX spokesperson James Gleeson told FLORIDA TODAY. “The fire was contained to a sea van on site and extinguished thanks to the Cocoa Fire Department, which responded within minutes.”

“There were no injuries as a result of the fire, and the cause is under investigation,” he said.

Martinez said the fire department estimates about $50,000 to $100,000 in damages were sustained by the shipping container and equipment inside, as well as the adjacent building.

This will be a blow to the Florida SpaceX unit that is competing with the Boca Chica unit on the construction of Starship.

SpaceX seeking more investment capital

Points of Information

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

Points of Information

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

Points of Information

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.

Starhopper completes first tethered hop

Points of Information

Capitalism in space: SpaceX’s prototype vehicle for testing vertical takeoff and landing for its Starship spacecraft, now dubbed Starhopper, successfully completed its first tethered hop yesterday.

The company and Elon Musk have revealed few details, other than it was tethered, lasted only a very short time, and involved only one Raptor engine. More tests are certain to follow.

Update of Starhopper testing in Texas

Points of Information

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?

Points of Information

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

Points of Information

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?

Points of Information

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 ramps up Raptor engine tests

Points of Information

Capitalism in space: SpaceX has conducted another Raptor engine test, this time running the engine at full power.

“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.”

Musk has said that they will be doing hopper test flights with their Starship prototype this spring, but they can’t do that until they have three working Raptor engines. It seems to me that it will be at least a few months before this engine is tested sufficiently to be ready for flight. Then they need two more finished engines.

Don’t expect the first Starship hopper flights for at least six more months, if that soon.

SpaceX test fires next generation rocket engine

Points of Information

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

Points of Information

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

Points of Information

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

Points of Information

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

Points of Information

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.
