SpaceX rolls out next Starship prototype

Capitalism in space: SpaceX has completed construction of its next Starship prototype and has moved it to its test stand in preparation for further tests.

This is the fourth prototype. If the tank pressure tests go well, they hope to add engines and do a twelve mile hop with this prototype, landing vertically. If not, they will try again with later prototypes. Regardless, the goal is to do that hop this year.

SpaceX reuses sections of damaged Starship prototype for next version

Capitalism in space: In building its fourth Starship prototype for testing, SpaceX has decided to reuse large sections of the previous Starship prototype, badly damaged during a pressure test several weeks ago.

On April 15th, eight days after Starship SN3’s [the damaged third prototype] remaining aft section was cut in half, the rearmost half – known as the skirt – was spotted stacked beneath a brand new engine section built for SN4. While confirming that a significant part of SN3 will be reused on SN4, it also indicates that only a less critical SN3 remnant was fit to join SpaceX’s next prototype.

Though they are not reusing the engines from that third prototype, I have full confidence they will, as they were part of the same bottom section of that prototype that was damaged during the test. This statement is incorrect. I had mistakenly assumed that because SpaceX had said it planned actual test hops eventually with this third prototype that three engines were already in place. They were not.

Third Starship prototype collapses during tank pressure test

During the final part of a tank pressure test the third SpaceX Starship prototype apparently collapsed, its outer welded hull failing.

Video below the fold. The prototype is on the right, and it appears it fall inward along its hull welds.

The SN3 (Serial Number 3) vehicle incorporated lessons learned from previous vehicles and test articles, and took advantage of improved manufacturing techniques and expanded facilities at SpaceX’s South Texas launch facility.

The next round of testing began this week with cryogenic proof testing. These tests saw the vehicle filled with liquid nitrogen at cryogenic temperatures and flight pressures. Proof testing began in Thursday and continued through to Friday morning when SN3 failed during what appeared to be the end of the test.

With Elon Musk noting “we will see what data review says in the morning, but this may have been a test configuration mistake,” on Twitter and the first-look observations, the fault may have been related to detanking, rather than another failure under pressure.

I’m no engineer, so I wonder how detanking could cause such a failure.

SpaceX prepares next Starship prototype; releases Starship user manual

From SpaceX's first user manual for Starship

Capitalism in space: Even as SpaceX has begun preparing its third Starship prototype for new testing, it has also released a first user manual for the rocket, outlining its proposed capabilities and potential uses by customers.

From the first link:

The next round of testing is anticipated to begin this week with cryogenic proof testing. These tests will see the vehicle filled with liquid nitrogen at cryogenic temperatures and flight pressures. Prior Starship test vehicles have had their campaigns cut short by failed cryogenic testing, including the last flight vehicle SpaceX rolled to the Boca Chica launch pad, Starship SN1.

If all goes right, they hope to begin short flight tests with this prototype, moving to longer and higher flights with the next.

The user manual [pdf] is mostly a short description of what they hope they will be able to accomplish with Starship. It notes that they will build both a cargo and manned variety, and that both will be available for point-to-point transportation on Earth. It also notes:

Starship has the capability to transport satellites, payloads, crew, and cargo to a variety of orbits and
Earth, Lunar, or Martian landing sites. Potential Starship customers can use this guide as a resource for preliminary payload accommodations information.This is the initial release of the Starship Users Guide and it will be updated frequently in response to customer feedback.

I guarantee that much of what is written and drawn here, such as the illustration above, will change significantly as development proceeds.

More Boca Chica residents move out, accepting SpaceX offers

More Boca Chica residents have accepted SpaceX purchase offers, and are finding other places to live.

While not all are thrilled with the circumstances, the article suggests that there is far more good will then unhappiness. It appears the excitement of what SpaceX is doing, and its willingness to give these residents special viewing privileges in the future, has done wonders to ease the pain for many of them for having to sell their homes.

It has also produced youtube channels providing 24 hour live streams of SpaceX operations.

SpaceX raises $500 million for Starship, twice the amount planned

Capitalism in space: In a just completed fund-raising round, SpaceX raised twice the investment capital proposed, $500 million instead of $250 million.

These funds are in addition to the $1.33 billion raised previously. And according to the SpaceX official in charge of their Starlink satellite constellation, most of this money is not for Starlink:

While SpaceX expects it will cost about $10 billion or more to build the Starlink network, [vice president Jonathan] Hofeller said the company’s fundraising so far has largely not been directed to the Starlink division, as “we’ve been able to fund the development of Starlink primarily from our internal businesses.” He declared the company is in a “different position” in how it raises funds compared to other companies that are building satellite networks. “That’s why, in general, we’ve been very quiet about what we’re doing because we don’t need to go out and raise money for this particular venture,” Hofeller said.

This means the $1.83 billion raised is almost certainly all for developing Starship/Super Heavy.

Can SpaceX build this new heavy lift completely reusable rocket for that price? Considering that it cost them $500 million to develop Falcon Heavy, and that much of the engineering work from that will be applicable for the new rocket, I am willing to bet that they can.

My prediction is further reinforced by the company’s recent activities testing Starship’s tanks at Boca Chica, Texas. Only two weeks after a test to failure (resulting in some spectacular fireworks), the company has apparently successfully completed new tank tests on the next prototype.

In other words, they blew up a prototype, were able to clean up the mess, redesign what failed, and test it successfully, in only two weeks. To say such a pace would be impossible for NASA and its big space contractors like Boeing is probably the biggest understatement I’ve ever made.

This success should not make anyone think that the challenge of building Starship/Super Heavy will be easy or fast. This effort will be cutting edge engineering that in many ways will be beyond that edge. SpaceX is guaranteed to have further test failures along the way. Their pace, management approach, and track record however shows that the company knows how to deal with such issues, and will thus be able to proceed to completion.

Explosion during static fire test of SpaceX’s Starship-SN1 prototype

Capitalism in space: It appears that about two seconds into a static fire engine test tonight of SpaceX’s Starship-SN1 prototype, something went wrong, there was an explosion, the prototype suddenly lifted into the air and then crashed to the ground in a bigger explosion.

The video below shows the event three times. We shall have to await word from SpaceX as to what happened. So far it appears that no one was hurt.

Starship moved to launch site

Capitalism in space: SpaceX’s Starship-SN1 prototype has been transported to its launch site at Boca Chica in preparation for a series of tests prior to its first launch hop, hopefully to a height of 12 miles.

Whether SN01 is still destined for flight, it’s safe to say that Starship SN01 tank testing could begin in a matter of days — SpaceX currently has early-morning roadblocks indicative of such testing scheduled from February 29th to March 2nd. SpaceX is likely to kick off by filling SN01 with water to check its tanks for leaks, followed by liquid nitrogen – chemically neutral but still incredibly cold. After that, SN01 would likely graduate to Raptor engine installation and a wet dress rehearsal (WDR) with liquid oxygen and methane before moving on to a static fire attempt, if all goes well.

I have embedded below the fold a fifteen minute video showing the transport operation. The pace is slow, so I suggest playing it at 2x normal speed, using the settings.

My immediate thought in watching this video is that SpaceX’s mobile transport vehicle certainly cost far less than the two mobile launchers NASA built for SLS (for a cost of about a billion dollars). In fact, SpaceX’s entire Starship development program will likely cost less than what NASA spent on just its mobile launchers.

SpaceX gets approval for Starship/Super Heavy factory in LA

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.

A bullseye on Mars

Bullseye crater on Mars
Click for full image.

Cool image time! The photo on the right, cropped and reduced to post here, was taken by the high resolution camera of Mars Reconnaissance Orbiter (MRO) on November 30, 2019. It shows a lone crater on the flat northern lowlands of Mars in a region dubbed Arcadia Planitia.

The crater is intriguing because of its concentric ridges and central pit. As this region is known to have a great deal of subsurface water ice, close to the surface, these features were probably caused at impact. My guess is that the ice quickly melted, formed the kind circular ripples you see when you toss a pebble in a pond, but then quickly refroze again, in place.

This location is also of interest in that is it just north of the region that SpaceX considers the prime candidate landing site for its Starship manned spaceship.

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

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.

SpaceX wins first new launch contract in 2020

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.

Further explorations at candidate Starship Mars landing site

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

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

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 Phlegra 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?

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

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.
