SpaceX in preliminary negotiations for another big fundraising round

9:07 am

Capitalism in space: According to this report, SpaceX is now in preliminary negotiations with investors prior to beginning another big fundraising round, even though the company just raised $1.9 billion in private investment capital in August.

The talks are still in early phases, and exact pricing for the fundraising round has not yet been determined, one of the people said. Terms could still change, and it could take several weeks to decide and firm up allocations, the person added. SpaceX also may not be able to convince investors to give it the lofty valuation it desires. Allocations refer to which investors will be authorized to buy shares and how much they will pay for those shares.

“It’s a pretty big shock to me, honestly,” one of the people said. “What company jumps to double its valuation in six months? I don’t care at what scale you’re operating, it’s kind of crazy,” they added. “If you look at the series, every single valuation is a 10 to 20% bump.”

It appears that the company is trying to leverage its successes with Dragon, Starship, and Starlink to obtain more funding. The story also suggests that SpaceX now has a better sense of what it will cost to get Starship built, and thus is looking to obtain those funds now, when they are in a good position to get them.

Indonesia & SpaceX considering launchsite there

8:26 am

Capitalism in space: Indonesia has been in discussions with SpaceX and Elon Musk about establishing a SpaceX launch site in that country.

President Joko Widodo discussed the idea with SpaceX founder Elon Musk during a phone call on Friday, the Coordinating Ministry for Maritime and Investment Affairs said in the statement. Musk intends to send a team to Indonesia in January to study partnership opportunities, it said.

Makes sense for Musk to consider such a move, especially if the U.S. and Texas governments start to turn the screws on his Boca Chica launch site. Furthermore, it is his intention to eventually launch Starship/Super Heavy from a floating launch platform. Establishing arrangements with other foreign nations for putting it in their waters gives the company more flexibility.

People always migrate toward freedom. For two hundred and fifty years, that meant they moved to the United States. This now is changing, as the U.S. culture is signaling its increased hostility to this most important founding principle. Expect more stories like this in the coming decades.

Breaking: Starship prototype #9 tips over inside assembly building

12:43 pm

It appears from the 24-hour live stream provided by LabPadre that the ninth Starship prototype tipped over inside the assembly building to rest against one wall. You can see it happen at about 8 seconds into the video below:

No word on whether anyone was hurt, nor any information about the cause. My guess is that it occurred during the operations to move this prototype to the launchpad.

UPDATE: It appears no one was hurt, but there is damage to the fins, which might also mean damage to the hull. This in turn might make it unsafe to fly this prototype, as the hull forms the walls of the methane/oxygen tanks.

The day has not been good for SpaceX. Earlier they had to scrub the launch of a commercial communications satellite at T-30 seconds for reasons that they did not provide. High altitude winds had delayed the launch an hour or so, but it appears this was not the reason. According to SpaceX’s website, “SpaceX is standing down from Friday’s launch attempt of the SXM-7 mission to perform additional ground system checkouts.” They are targeting Sunday for the next launch attempt.

Starship: Old-fashioned American know-how

11:39 am

Starship about 2 minutes into its flight

Yesterday’s truly epic first flight of SpaceX’s giant Starship rocket illustrated several truths that bear repeating, in clear and forceful language.

SpaceX succeeded because its company philosophy is open-minded, fearless, and thus free.

The open-mindedness culture comes from Elon Musk’s insistence that they never settle on any design if they can find a better way to do it. It is this approach that drives the company’s developmental process. The first Falcon 1 rocket made orbit, but despite that triumph Musk quickly abandoned it for the Falcon 9 when it was clear that it wasn’t powerful enough to garner enough satellite business.

The Falcon 9 that first launched in 2008 was a very different rocket from the Falcon 9 that launches today, as shown by the two pictures below. In the 2008 Falcon 9 the engines were configured differently and it had no legs. The modern Falcon 9 has landing legs, a different engine arrangement, and much of the innards have been redesigned to give the rocket more oomph.

Starship flies!

4:31 pm

Starship about 2 minutes into its flight

Capitalism in space: In a spectacular achievement, SpaceX’s eighth Starship prototype today completed 6:42 minute flight that appeared to go practically perfectly, until landing.

At that point it appeared the spacecraft’s last landing burn was insufficient to slow it down enough for landing, and it crashed. However, it crashed on its landing pad, meaning it had maneuvered its way back through the atmosphere exactly as planned.

Below the fold are screen captures from the flight, in sequence.

The flight left several impressions. First, this design is viable. Though we are still looking at a prototype, it is one that works.

Second, the ship appeared to lumber into space, almost slowly. This was partly an illusion because of its size. Nonetheless, it reminded me of the 747, which always flew magnificently but with what seemed like a measured attitude. Starship appeared similar.

Third, the systems for controlling the ship on its return through the atmosphere appeared to work as intended. Though SpaceX obviously has a lot more work to do to achieve an orbital return, they have made a magnificent start.

And they have gotten this far in only two years, for less than $2 billion. Compare that to NASA and Boeing and their SLS, which is half a decade behind schedule and will likely cost $30 billion once launched.

We should expect the ninth prototype to be on the launchpad within days, and the next test flight in no more than few weeks.

Watch the attempted first high altitude flight of SpaceX’s Starship

UPDATE: Less than six minutes to launch.

UPDATE: Hold called at T-2:06. They have reset the clock for a 4:40 pm (Central) launch.

Original post:
——————-
Capitalism in space: SpaceX’s live stream is on, with a liftoff in six minutes. I have embedded below the fold the live stream for this first high altitude flight of SpaceX’s Starship.

The LabPadre live stream, to the right, shows that they have already proceeded through most of preliminary stages prior to liftoff.

If all goes right, this eighth prototype of Starship will go about 40,000 feet in the air, turn over and attempt to control its return belly side down, and then upright itself just before landing so it can complete a vertical landing like a Falcon 9 first stage. The company gives themselves a one in three chance of landing the spacecraft. SpaceX has also made it clear that their primary engineering goal on this flight is to test that return through the atmosphere, so that is the part of the flight they most need to succeed. Failing to land afterward but getting that data will make this test a complete success.

No matter what happens, the company has prototypes 9 through 15 waiting in the wings.

UPDATE: This post will remain at the top of the page until the flight occurs, or is scrubbed. Scroll down for new stories.

Launch abort for Starship high altitude flight

4:03 pm

Starship at T-1 second on launch pad
Screen capture from SpaceX live feed at T-1 second.
Click for LabPadre live stream.

The attempt today by SpaceX to fly its eighth prototype of Starship to 40,000 feet aborted at T-1 second, apparently because the rocket’s computers sensed something wrong and shut things down.

They have stood down for the day. At the moment there is no word on when they will try again, though they have a back up launch window for tomorrow, and SpaceX’s policy generally is to move forward quickly. The decision will likely depend on the reasons for the abort. I will bet they will try again tomorrow.

I have revised the the live feed post, removing references to today’s launch abort, since this information is now contained in this post. The live feed post however will remain at the top of the page.

Weather delays Starship hop to December 8th; Musk arrives in Boca Chica

9:38 am

Starship on launch pad
Click for LabPadre live stream from which this still was captured.

Capitalism in space: Weather issues have delayed the first big hop of the eighth Starship prototype so that it is now scheduled for no earlier than tomorrow, December 8th.

That Elon Musk arrived in Boca Chica late on December 5th strongly suggests however the hop will finally happen this week, after several weeks of delays.

With Musk himself now on the ground in Texas to (presumably) oversee Starship SN8’s debut, the odds of launch later this week are arguably much better. Having now spent more than 10 weeks at the launch pad, at least twice as long as any Starship preceding it, there’s no small chance that SN8 – the first prototype of its kind – is starting to be more of a nuisance than an asset. By all appearances, Starship SN9 – essentially a “refined” copy of SN8 – is practically ready for launch with SN10 perhaps just a week or two behind it.

It also appears they have lowered the top planned altitude of the hop from 50,000 feet to about 40,000 feet.

Musk had tweeted earlier that SpaceX planned to live stream the event, which would be spectacular as they almost certainly have cameras on the spacecraft. If they don’t the LabPadre live stream above will also be an option.

Starship 9-mile-high flight now set for no earlier than December 4th

9:13 am

Starship on launch pad
Click for LabPadre live stream from which this still was captured.

Capitalism in space: SpaceX has now scheduled the first 9-mile-high flight of its 8th Starship prototype for either December 4th, 5th, or 6th.

On Wednesday, the Federal Aviation Administration issued a temporary flight restriction for SpaceX to conduct a Starship launch from its facility near Boca Chica Beach in South Texas. The notification allows the company to attempt a Starship hop on Friday, Saturday, or Sunday, between the hours of 9am EST (14:00 UTC) and 6pm EST (23:00 UTC) daily. SpaceX must still obtain a launch license from the FAA for this flight.

The company’s founder and chief engineer, Elon Musk, has said SpaceX will attempt to fly Starship to an altitude of 15km to demonstrate the performance of three Raptor engines over the course of several minutes. The company’s previous flights to about 150 meters, in August and September, used a single Raptor engine.

This higher flight profile will take Starship above nearly 90 percent of Earth’s atmosphere, which will allow the company to do several new tests: assess the performance of body flaps on Starship, transition from using propellant from the main fuel tanks to smaller ones used for landing burns, and test the vehicle’s ability to reorient itself for returning to the launch site.

Look closely at the screen capture of Starship above. Note how there is no launch tower at all, and that the launchpad is simply a platform on which the ship sits. This lack indicates two things. First, the ship’s large diameter gives it a much lower center of gravity compared to all other rockets. It doesn’t need the launch tower for support. This is why SpaceX can move it back and forth from the assembly building on the equivalent of a large flatbed truck.

Second, the lack illustrates SpaceX’s lean and mean engineering style. When this spacecraft finally launches to orbit on top of a Super Heavy first stage, it will certainly need a launch tower, not so much for support but to fuel it and allow access to and from while on the launchpad. None of this infrastructure however is needed now for the ongoing development work. Why waste money and time building it when they don’t yet know the exact specifications of the final rocket itself?

SpaceX is taking advantage of the first point to do the second, thus speeding development and lowering its cost.

Starship 50,000 ft hop now scheduled for Nov 30th

8:35 am

Capitalism in space: Having completed all preliminary static fire tests, SpaceX has now set November 30th as the target date for 50,000 foot high hop for its eighth Starship prototype.

SpaceX is understood to be conducting a Flight Readiness Review (FRR) for the test flight, with this final Static Fire test providing key data to the final go to proceed towards SN8’s big day.

Elon Musk has already calibrated public expectations on the expected outcome of SN8’s test, noting that “understanding exactly how the body flaps control pitch, yaw & roll during descent, such that the ship is positioned well to relight, flip & land, would be a big win.” As opposed to expecting SN8 to land feet first on the landing pad.

Musk’s point is important. The primary engineering goal for this first hop will be to find out whether they truly understand how to control and fly Starship. Their knowledge in this area is only computer based, and thus is very incomplete, and could very well be wrong, resulting in a failure that prevents a proper clean landing.

Such as failure however would actually be an engineering success, as it would give them the data needed to make later prototypes work. As for landing, they know how to do that already. Once they get the flying right, the landing should follow.

SpaceX has said it will live stream that hop. Should be a thrill to watch.

Regulators coming after SpaceX’s Boca Chica facility and Starship

9:05 am

Capitalism in space? New FAA documents suggest that government regulators are not happy with the rapid and spectacular development by SpaceX of its Super Heavy/Starship rocket at Boca Chica, Texas, and are eager to impose restrictions and delays.

The issue revolves around revisions to SpaceX’s original FAA approval for its work at Boca Chica because the company has switched from flying Falcon 9 and Falcon Heavy rockets to developing and flying Starship and Super Heavy. While the FAA has been cooperative in issuing the necessary revisions, other agencies have raised red flags.

But the most important document of the bunch is the written reevaluation signed by the FAA on May 22. The file spans 26 pages, was required for SpaceX to receive its suborbital launch license from the FAA on May 28, and incorporates concerns from state and federal environmental agencies.

In the reevaluation, the Texas Parks and Wildlife Department and the US Fish and Wildlife Service took issue with several aspects of SpaceX’s plans and ongoing activities. Those criticisms targeted the “fluid nature” of the company’s construction projects, excessive road closures to Boca Chica Beach (which Brownsville locals prize), around-the-clock work that may affect nocturnal threatened or endangered species, prototype explosions, and sprawling wildfires the company has triggered.

The FAA responded to each concern in the document, ultimately determining “there are no significant environmental changes, and that all pertinent conditions and requirements of the prior approval have been met or will be met” with SpaceX’s suborbital test-flight plans.

However, SpaceX does not yet have the FAA’s go-ahead to launch any Starships to orbit from Boca Chica.

In its replies to concerns noted by other agencies — some of which call for a new EIS [environmental impact statement], which could take years to complete (an eternity in Musk time) — the agency repeatedly noted it is working with SpaceX to draft an “environmental review” of those plans.

Should Joe Biden and the power-hungry and controlling Democrats take control of the executive branch of the federal government, expect the FAA’s desire to help SpaceX to quickly end.

Most recent engine test on eighth Starship prototype had issues

8:52 am

Capitalism in space: The most recent engine test on November 12th of SpaceX’s eighth Starship prototype had a problem that will delay its planned 50,000 foot test hop.

The Starship SN8 vehicle performed its third brief “static fire” — a test in which engines are ignited while a rocket remains tethered to the ground — at SpaceX’s South Texas facility on Thursday, near the village of Boca Chica.

Shortly after the test, which several outside organizations webcast live, material could be seen apparently dripping from SN8’s base. This looked odd, and SpaceX founder and CEO Elon Musk soon confirmed that something off-nominal had happened. “We lost vehicle pneumatics. Reason unknown at present. Liquid oxygen header tank pressure is rising. Hopefully triggers burst disk to relieve pressure, otherwise it’s going to pop the cork,” Musk said via Twitter on Thursday night. (Burst disks are single-use devices that, like valves, seal off different sections or systems of a vehicle. They relieve pressure when they open, as Musk noted.)

The cause of the problem is unknown at the moment, Musk said in another Thursday tweet: “Maybe melted an engine preburner or fuel hot gas manifold. Whatever it is caused pneumatics loss. We need to design out this problem.”

The decision to pin down the cause and redesign things so it won’t happen again makes perfect sense, but it also means that the hop will not occur in the next week or so, as hoped for by the company. Expect a delay. Based on the pace that SpaceX works, that delay however should not be longer than one or two months.

Update on continuing engine testing of Starship prototype #8

8:45 am

Link here. The article provides details on the on-going engine tests of SpaceX’s eighth prototype of its Starship reusuable upper stage.

As should be expected, the testing has not gone exactly as planned, though clear progress is being made, especially in the testing of the header tanks in the nosecone..

After several days of test windows come and gone and an aborted attempt on November 9th, Starship SN8 finally ignited one of its three Raptor engines, feeding the engine with liquid methane and oxygen stored in two separate header tanks. Oddly, a second or two after startup and ignition, Raptor’s usual exhaust plume was joined by a burst of shiny firework-like debris. A relatively normal five seconds later, the Raptor cut off, though the engine appeared to remain partially on fire for another ten or so seconds – also somewhat unusual.

It appears that fire was from nearby debris, not the engine itself.

Another engine test is likely later this week. The actual 50,000 foot hop will not happen until they have completed all these engine tests.

Starship hop tentatively set for Nov 9-11

8:59 am

Capitalism in space: Based on SpaceX’s road closure requests, it now appears that the 50,000 foot hop by the eighth Starship prototype will occur sometime between November 9th and November 11th.

This schedule remains very uncertain, as the company needs to do other tests before the hop. Depending on when these tests happen and what they learn after each, the overall schedule might change.

SpaceX to live stream 50,000 foot hop of Starship

9:20 am

Capitalism in space: Elon Musk yesterday announced that SpaceX will publicly live stream the 50,000-foot hop of Starship prototype #8, expected sometime in the next two weeks. His tweet:

Sure, although it might be quite a short livestream! Lot can go wrong, but we’ll provide video, warts & all. You will see every frame that we do.

Up until now the public has had to depend on the independent live streams being put out by local residents still living in Boca Chica, Texas, which did not know SpaceX’s exact schedule. When SpaceX does it they will likely provide more specific launch times. They will also probably provide detailed accurate commentary.

Also, this update on the status of Starship development notes that the primary goal of that hop is testing the ability of the ship’s fins and systems to control the ship’s initial descent on its return to Earth, flying on its side like the Space Shuttle. If they have problems getting the ship upright for a vertical landing and it ends up in the ocean that will not surprise them. A successful vertical landing would be icing on the cake.

Reviewing the development of Starship/Super Heavy

10:11 am

Link here. This five-part article is a detailed review of SpaceX’s development of its new completely reusable heavy-lift rocket, with Super Heavy being the first stage booster and Starship being the orbital upper stage capable of returning to Earth, landing vertically, and being reused.

From the article’s conclusion:

The Starship program is unique and one of the most ambitious in the history of rocketry. The design has now gone through at least twelve known versions and four different names!

Its first version was a single or triple-core rocket back in 2013, which has evolved into the single-core stainless steel Starship design under construction today. Even as the design’s size has fluctuated dramatically, its repertoire of missions and roles has expanded.

It started out as a rocket meant to colonize Mars but now is envisioned as an all-purpose carrier rocket to replace the Falcon 9 rocket family. It is expected to launch satellites into Earth orbit, fly people point-to-point on Earth, ferry cargo and crew to and from the Moon, in addition to its original role as a Mars colonization vehicle.

Two significant points: First, SpaceX as a company has shown itself remarkably capable of shifting design and development tracks, on a dime, if it realized there was a better way to do things. Second, the company has also smartly rethought this big rocket’s reason for existing. In the beginning they focused on Musk’s goal of getting to Mars. That concept however had few if no customers, and therefore have little chance of producing profits. Overtime the company adjusted their design goals to expand the rocket’s purposes so that its capabilities would serve as many customers as possible.

The result is a useful product that still could take people to Mars.

Starship prototype #8 gets its nosecone

10:09 am

Starship prototype #8, with nosecone
Screen capture from LabPadre live stream.

Capitalism in space: SpaceX has now installed the nosecone on Starship prototype #8 in advance of its first vertical hop to 50,000 feet, or more than ten miles, expected sometime in November.

Curiously, hours prior to nose installation, SpaceX apparently removed one of Starship SN8’s three Raptor engines while also revealing that a spare fourth engine was already in Boca Chica. In other words, the prototype likely has only two Raptor engines installed at the moment, meaning that SpaceX will need to install another before the company can prepare for SN8’s next major test campaign.

According to CEO Elon Musk, the plan was to static fire Starship SN8’s three Raptor engines, perform final inspections and checkouts, perform another static fire, and finally attempt the first high-attitude Starship flight test. As of October 22nd, SpaceX has seemingly completed the two steps. Nosecone freshly installed, it’s likely that SpaceX will use the second triple-Raptor static fire opportunity to test the engines while feeding propellant solely from Starship’s liquid oxygen and methane header tanks – the latter of which is located in the nose.

The removal of one engine suggests they found something in that engine they didn’t like during last week’s static fire test, though that is mere speculation on my part.

The addition of the nosecone, with its own fins, clearly changes the appearance of prototype #8, making it look truly like a rocket ship. In fact, it looks more like the rocket ship imagined by science fiction writers for decades prior to the advent of spaceflight in the 1960s. The irony is that this is the first real rocket since the V2 in World War II to have this look.

SpaceX completes static fire test on Starship prototype #8

9:09 am

Capitalism in space: SpaceX last night successfully completed the static fire test on its eighth Starship prototype, for the first time firing three Raptor engines simultanously.

Video of the test, cued to just before ignition, is embedded below the fold.

The company will now install the nosecone on the prototype, repeat this static fire test again in about a week, and then prepare it for its first flight, an expected 50,000 foot hop. I expect that hop to occur in early to mid-November, about the same time the next manned Dragon flight will occur.

SpaceX begins installing Raptor engines on Starship prototype #8

9:47 am

Capitalism in space: With Starship prototype having successfully passed its tank tests SpaceX has begun installing three Raptor engines in preparation for static fire tests followed by a 50,000 foot high hop.

Once the Raptors are installed, Starship SN8 is expected to undergo an extensive test program, opening with fueling tests, a spin prime test, and preburner tests, before the first Static Fire test.

That opening Static Fire test will be the first time three Raptors have been fired up simultaneously.

Once that opening Static Fire test has been completed, a data review will be conducted on engine performance and related systems – such as the Ground Support Equipment (GSE) – which will allow the nosecone to be installed on to SN8 at the launch site.

At that point the prototype will be ready for its hop. Based on the pace SpaceX is setting (and assuming all goes well), this flight should occur sometime in the next month, possibly at almost the same time as the next manned Dragon flight to ISS.
