Watching the second attempt to launch Starship/Superheavy to orbit

Starship/Superheavy flight plan for first orbital flight
Click for original image.

SpaceX’s second attempt of an inaugural orbital test launch of SpaceX’s massive Superheavy first stage with its orbital Starship spacecraft stacked on top has now been rescheduled for Thursday, April 20, 2023, with a 62-minute launch window opening at 8:28 am Central.

I have embedded SpaceX’s live stream of that launch below, which will begin around 7:15 am (Central). You can also see an independent 24/7 live stream from LabPadre, showing the launchpad from many different angles and available here. NasaSpaceFlight.com also has a 24/7 live stream showing multiple angles here. For both, to see links to their many camera angles click on “more” in the text.

Though both of these independent live streams provide alternative view angles of the launch, both will rely on SpaceX’s main live stream, embedded below, for actual updates on the countdown status.

The flight plan is shown in the graphic above. Assuming all goes as planned, most of the action will occur in the first ten minutes, at which time Starship will cut off its engines and be in orbit. It will then coast for a little over an hour when it will re-enter the atmosphere to splashdown in the Pacific north of the Hawaiian Islands.

As I have noted many times, the historical significance of this rocket cannot be overstated. It is twice as powerful as NASA’s Saturn-5 rocket and almost three-times as powerful as NASA’s new SLS rocket, and went from concept to launch in about seven years. Its development was funded entirely by private investment capital, at a fraction of the cost of either of the government’s rockets. And it will be completely reusable once operational, reducing the cost exponentially of getting large 100-ton payloads into orbit.

And most important, it was developed by free Americans, following their own personal dreams.

Starship/Superheavy launch scrubbed

Because of “a pressurization issue”, SpaceX engineers decided to scrub today’s first test launch of Starship/Superheavy. The launch team then made this launch attempt a wet dress countdown rehearsal, ending at T-40 seconds.

Because of the amount of fuel and oxygen involved, turn-around will take 48 hours, meaning the next launch attempt will likely occur on Wednesday, April 19, 2023, probably at the same approximate time in the morning.

Stay tuned for more details.

The first orbital test launch of SpaceX’s massive Superheavy first stage with its orbital Starship spacecraft stacked on top is now scheduled for a launch in a two-and-a-half hour long launch window beginning at 8 am (Central) on Monday, April 17, 2023.

I have embedded SpaceX’s live stream of that launch below, which will begin around 7 am (Central). You can also see an independent 24/7 live stream from LabPadre, showing the launchpad from many different angles and available here. NasaSpaceFlight.com also has a 24/7 live stream showing multiple angles here. Though both of these independent live streams provide alternative view angles of the launch, both will rely on SpaceX’s main live stream, embedded below, for actual updates on the countdown status.

If the launch is scrubbed on April 17th, SpacX has backup dates on April 18th and 19th. The flight plan and time line is shown in the graphic above.

The monumental significance of this rocket cannot be overstated. It is the most powerful rocket ever built, capable of putting more mass into orbit than either the Saturn-5 or NASA’s new SLS rocket.

It took less than seven years from concept to launch. Compare that to SLS, which was proposed in 2004 and only launched last year, two decades later.

It has been been entirely developed with private funds. Though SpaceX does have a NASA contract for building a Starship lunar lander, little of that contract’s funds have yet been distributed to the company. From private funds SpaceX has raised about $10 billion, most of which has been channeled into this rocket’s development, with a small unknown amount used to develop Starlink. Compare that once again to SLS, which has cost about $60 billion to build.

Finally, it is being designed to be completely reusable, thus reducing the cost exponentially for putting large 100-ton payloads into orbit. If successful, Starship/Superheavy will very quickly make the human exploration and colonization of the solar system possible.

And it will do so not as a government project that is part of a government program, but as a private sector product, conceived by individual Americans freely following their dreams, and developed for profit, quickly and efficiently.

FAA issues Starship launch license; SpaceX schedules launch for April 17th

Starship stacked on top of Superheavy
Starship prototype #24 stacked on top of Superheavy prototype #7

FAA just sent out an email notice announcing that it has issued SpaceX the launch license for the first orbital test launch of Superheavy/Starship.

After completing an evaluation of all applicable Vehicle Operator License requirements, the Federal Aviation Administration (FAA) issued a commercial Vehicle Operator License to SpaceX for launches of the Starship/Super Heavy Launch Vehicle Program in Cameron County, TX.

The affected environment and environmental impacts of Starship/Super Heavy operations at the Boca Chica Launch Site had been analyzed in the 2022 Final Programmatic Environmental Assessment for the SpaceX Starship/Super Heavy Launch Vehicle Program at the SpaceX Boca Chica Launch Site in Cameron County, Texas. Since the 2022 Programmatic Environmental Assessment (PEA), SpaceX provided the FAA with additional information regarding Starship’s planned landing, Super Heavy’s planned soft water landing, and the Launch Pad Detonation Suppression System. In accordance with FAA Order 1050.1F, Environmental Impacts: Policies and Procedures, the FAA prepared the Written Re-evaluation of the 2022 Final Programmatic Environmental Assessment for the SpaceX Starship/Super Heavy Launch Vehicle Program at the Boca Chica Launch Site in Cameron County, Texas to describe and evaluate this additional information.

Based on the Written Re-Evaluation, the FAA concluded that the issuance of a vehicle operator license for Starship/Super Heavy operations conforms to the prior environmental documentation, that the data contained in the 2022 PEA remains substantially valid, that there are no significant environmental changes, and all pertinent conditions and requirements of the prior approval have been met or will be met in the current action. Therefore, preparation of a supplemental or new environmental document is not necessary to support the Proposed Action.

In plain English, the FAA (and other federal agencies) have finally agreed that this launch will do nothing to change the conclusions of the environmental reassessment report that was approved in June 2022. That these agencies decided apparently decided to rehash that approved environmental reassessment for a launch that was also approved in that reassessment suggests that there are individuals in these agencies salivating for an opportunity to squelch SpaceX.

SpaceX has now set April 17, 2023 as the launch date, with its live stream going live in two days. I will embed that live stream late on April 16, 2023, for those who wish to watch it here.

SpaceX announces it will be providing a webcast for Starship’s first orbital flight

Starship/Superheavy flight plan for first orbital flight
Click for original image.

SpaceX today revealed the details for its live stream of the first orbital launch of Superheavy/Starship, now targeting a launch date around April 21, 2023, depending on when the FAA issues the launch license.

A live webcast of the flight test will begin ~45 minutes before liftoff. As is the case with all developmental testing, this schedule is dynamic and likely to change, so be sure to stay tuned to our social media channels for updates.

I will embed that live stream here on Behind the Black. Stay tuned for more information.

The flight plan is shown above. The website also provides a detailed timeline. If launch manages to pass through Max-Q and get to stage separation, Superheavy will do a flip to do a soft targeted landing in the Gulf of Mexico. Starship will continue into orbit, and then fire its engines to return to Earth to do a soft targeted landing in the Pacific northeast of the Big Island of Hawaii.

That is the plan. Much can go wrong along the way, considering Superheavy has never flown once, no less with Starship stacked on top. Furthermore, Starship has never flown in its present iteration. Previous suborbital tests were using much earlier prototypes vastly different that this prototype, #24 in the series.

Regardless whether all goes perfectly or some things fail, the launch will be a success because it will provide SpaceX data for future test flights, which are waiting in the wings.

Starship orbital test flight delayed one more week due to FAA delays

According to a tweet yesterday by Elon Musk, the first orbital test flight of Starship/Superheavy has been delayed again.

Starship launch trending towards near the end of third week of April

Musk had made it clear in an April 8th tweet the cause of this delay or any other delays:

Starship is ready for launch. Awaiting regulatory approval

Musk needs to be somewhat diplomatic as it will not help him to make federal bureaucrats his enemies. What he is doing here is subtly letting everyone know the sole cause of the delay, in order to press the FAA to get a move on, without saying so directly. He leaves that to others, such as myself, to say it instead.

I fear that the FAA is now demanding that it must look at the data from any wet dress rehearsal countdown, including the short engine burst that Superheavy will likely do at T-0, before it will issue the permit. If so, we could see more than a week delay. The launch should easily slip to late May if not later.

The absurdity of this is that it is utterly pointless for FAA bureaucrats to look at any of this data. What do they know? Nothing. If something was significantly wrong SpaceX engineers would know far sooner, and delay the launch themselves.

The delays seen in issuing this one launch license however give us a nice picture of what it will be like for the launch industry once the moratorium on heavy regulations by the FAA and other federal agencies expires on October 1, 2023. Expect a substantial slowdown in development and launches, with many of the new companies about to become operational instead going bankrupt in a replay of the destruction of Virgin Orbit by the UK’s Civil Aviation Authority.

Starship now stacked on launchpad

Starship stacked on top of Superheavy

In preparation for a final wet dress rehearsal countdown followed by its first launch, Starship has now been stacked on top of Superheavy at SpaceX’s launchpad at Boca Chica, Texas.

The picture to the right is a screen capture from a short video Elon Musk posted on Twitter. SpaceX had also tweeted that its “Team is working towards a launch rehearsal next week [April 10-11] followed by Starship’s first integrated flight test ~week later pending regulatory approval.”

At this time the FAA has still not issued the launch license. By announcing its plan to launch the week of April 17th, Musk and SpaceX puts pressure the government bureaucracy to get a move on.

FAA issues travel advisory for Boca Chica for April 10, 2023 Starship launch

Though the FAA has not yet issued the launch license to SpaceX, allowing it to do the first orbital launch test of its Superheavy/Starship rocket, the agency today did issue a travel advisory for the Boca Chica area for April 10-11, 2023, in connection with this launch.

The FAA advisory is here. Scroll down to see the space activities section, which includes this information:

SPACEX STARSHIP SUPERHEAVY BOCA CHICA, TX
PRIMARY: 04/10/23 1310-1745Z
BACKUP(S): 04/11-12/23 1310-1745Z

Based on this information, we should expect the FAA launch license to be publicly announced any moment.

Starship and Superheavy readied for orbital flight

With Superheavy prototype #7 already on the launchpad at Boca Chica, Texas, SpaceX engineers yesterday moved Starship prototype #24 beside it in preparation for stacking the orbital spacecraft on top of Superheavy for a launch now expected no earlier than April 10, 2023.

As the article notes, when Superheavy lifts off, it will set a new record for the most powerful rocket, having twice the thrust of either of NASA’s Saturn-5 or SLS rockets. And this record will be achieved by a privately built and owned rocket whose development has been funded almost entirely by private investment capital. Note too that the development took about six years, from concept to first launch, a few years less than it took NASA to build the Saturn-5 in the 1960s, and about one third the time it NASA to do the same thing with SLS in the 2000s, the 2010s, and the 2020s.

The orbital mission, it successful, will have Superheavy lift off, separate from Starship and then land controlled in the Gulf of Mexico. Starship will continue into orbit, and then attempt a controlled vertical splashdown in the Pacific Ocean northwest of the big Island of Hawaii.

At the moment, it appears the only obstacle to launch remains the FAA, which after many months has still not issued the launch license. This new activity at Boca Chica however suggests SpaceX expects that approval to occur momentarily.

SpaceX might get investment capital from Saudi and UAE investors

According to several reports in the business press, SpaceX is presently negotiating with investment companies in Saudi Arabia and the United Arab Emirates (UAE) to possibly provide additional investment capital to the company.

Citing two individuals reportedly familiar with the matter, The Information noted that Saudi Arabia’s Water and Electricity Holding Company, Badeel, and the United Arab Emirates’ Alpha Dhabi are participating in the funding round. Morgan Stanley is reportedly organizing the investment effort.

At present it is unknown how much would be invested. It is also unclear if this foreign investment in an American rocket company can pass muster with the U.S. State Department.

SpaceX has already raised about $10 billion in private investment capital as well as $4 billion from NASA for the development of Starship/Superheavy.

Starship launch still stalled by FAA

According to a tweet by Elon Musk today, Starship will be ready for its first orbital test launch in a few weeks.

Musk also noted however that SpaceX is still awaiting the FAA’s launch license, and because of this he now expects the launch in the third week in April.

Why it is taking months for the FAA to issue this license is disturbing, and suggests that under the Biden administration the feds are behaving more and more like the incompetent Civil Aviation Authority in the UK, which stonewalled Virgin Orbit’s launch for months so that the company now sits on the verge of bankruptcy.

Hat tip to BtB’s stringer Jay for this story, who will be gone for the next two weeks on vacation. Have fun Jay.

What to expect when SpaceX launches Starship on its first orbital flight

Link here. The article does a careful review of the previous dress rehearsal countdowns and static fire tests, especially the last which successfully fired 31 of Superheavy’s 33 Raptor-2 engines for 7 seconds, in order to understand what will happen during the countdown on the day the rocket does its first orbital launch, now expected within weeks.

It appears right now that SpaceX is preparing to replace one or both of those failed engines, and do it with Superheavy prototype #7 still mounted to the launchpad. Starship prototype #24 has not yet been stacked on top, but work is presently being done to it nearby to prepare it for launch. For example, workers recently have removed the attachment points used by cranes before the chopsticks existed and put thermal tiles there instead.

Based on the pace of work, SpaceX should be ready to launch by mid-March. All that will prevent this will be the FAA, which still has not approved the launch license.

SpaceX ready to launch Starship prototype #24 into orbit

According to a statement yesterday by one SpaceX official, the company is now ready to launch its Superheavy #7 booster, stacked with its Starship prototype #24, on an orbital test flight, with the only remaining obstacle to launch the launch license, not yet approved by the FAA.

Speaking on a panel at the Space Mobility conference here about “rocket cargo” delivery, Gary Henry, senior advisor for national security space solutions at SpaceX, said both the Super Heavy booster and its launch pad were in good shape after the Feb. 9 test, clearing the way for an orbital launch that is still pending a Federal Aviation Administration launch license. “We had a successful hot fire, and that was really the last box to check,” he said. “The vehicle is in good shape. The pad is in good shape.”

…“Pretty much all of the prerequisites to supporting an orbital demonstration attempt here in the next month or so look good,” he said.

Henry also outlined SpaceX’s overall plans for Starship in the next year or two, beginning with a series of test/operational launches that will iron out the kinks of the rocket while simultaneously placing Starlink satellites into orbit. At the same time, development will shift to creating a Moon lander version of Starship for NASA’S Artemis program, including doing refueling tests of Starship in orbit. These test flights will also lead quickly to the three private manned flights that SpaceX already has contracts for, including two around the Moon and one in Earth orbit.

SpaceX abandons plan to convert floating oil platforms into Starship/Superheavy landing spots

SpaceX has decided not to convert the two floating oil rigs it had purchased in 2020 into Starship/Superheavy landing platforms, and has sold both.

According to SpaceX CEO Gwynne Shotwell,

Shotwell said the company needed to first start launching Starship and better understand that vehicle before building offshore launch platforms. “We really need to fly this vehicle to understand it, to get to know this machine, and then we’ll figure out how we’re going to launch it.”

She said she expected offshore platforms to eventually play a role to support an extraordinarily high launch cadence. “We have designed Starship to be as much like aircraft operations as we possibly can get it,” she said in the conference presentation. “We want to talk about dozens of launches a day, if not hundreds of launches a day.”

This is a perfect example of this company’s intelligent ability to focus on the most important problems now, instead of getting distracted by future issues and challenges it knows exists but are not the priority at this time.

SpaceX completes 33-engine static fire test today of Superheavy prototype #7

Two seconds after ignition
Today’s Superheavy static fire test

SpaceX today successfully completed a 7-second-long static fire test of 31 of 33 Raptor-2 engines at the base Superheavy #7. The test ran for its full duration, and it appears no damage occurred to the launchpad. One engine shut down prior to test, and one shut down prematurely during the test. If this had happened during launch, the booster would still have had enough energy to get Starship to its required velocity to reach orbit.

The company will now have to analyze the test to determine whether it was sufficient to proceed to a March orbital launch. Certainly they will roll the booster back to the assembly building to exchange out the two engines that misfired.

All in all, it appears an orbital test flight of Starship could occur sometime in the next two months, assuming the FAA gets out of the way and issues the launch license.

EARLIER UPDATE:
—————-
Propellant loading is underway, and a rough time estimate for the actual static fire test is now 3 pm (Central).

Musk has now confirmed in a tweet that they are going to proceed to the test. It now appears that they have almost completed propellant loading. It appears they have filled the oxygen tanks, but not the methane tanks, and will probably not fill the methane tanks entirely for the test itself.

Original post:
—————-
No specific schedule has been announced of SpaceX’s attempt today to complete the first full 33-engine static fire test in Boca Chica of its seventh prototype of Superheavy, but a live stream is available from NASAspaceflight.com. I have embedded that live stream below.

The test will validate numerous systems, including the ground systems, the launchpad, the engines, and the systems for igniting all 33 in the proper sequence. Starship prototype #24 is not stacked on top of Superheavy in order to prevent any damage to it in case this test goes ugly. If so, SpaceX already has Superheavy prototype #9 ready to go in the nearby assembly building.

Stacked Starship and Superheavy complete first full wet dress rehearsal countdown

SpaceX yesterday successfully completed a full wet dress rehearsal countdown of its stacked Starship prototype #24 and Superheavy prototype #7, fueling both completely and taking the countdown down to T-0.

On this rehearsal however the Superheavy engines were not fired. From two SpaceX tweets:

Starship completed its first full flight-like wet dress rehearsal at Starbase today. This was the first time an integrated Ship and Booster were fully loaded with more than 10 million pounds of propellant

Today’s test will help verify a full launch countdown sequence, as well as the performance of Starship and the orbital pad for flight-like operations

Next step: Another full wet dress rehearsal countdown that includes a short static fire test of all 33 Superheavy Raptor-2 engines. Once that is done successfully, the company will be ready for that first orbital launch.

Meanwhile, SpaceX awaits its launch license from the FAA. I remain pessimistic that it will be issued on a timely manner, as there are clear signs the Biden administration wants to use its power against Musk, whom it now sees as an enemy.

SpaceX to build five Starship/Superheavy prototypes in 2023

According to Elon Musk, SpaceX intends to build five Starship/Superheavy prototypes in 2023 for flight testing.

Assuming they can get launch permits, these five rockets should provide the company ample launch testing capability for at least the next two years, especially if it succeeds in landing these units and can consider reusing them in test flights.

At this moment, the launch permits from the federal government appears the main obstacle to getting this heavy lift reusable rocket tested and operational.

Musk: SpaceX is now targeting late February/March for 1st orbital launch of Starship

According to a tweet put out by Elon Musk on January 8, 2023, SpaceX is now targeting late February/March for 1st orbital launch of the 24th prototype of Starship and the seventh prototype of Superheavy.

The testing in 2022 has not gone as smoothly as hoped, and is the reason no launch occurred last year:

Super Heavy B7 first left SpaceX’s Starbase factory in March 2022 and has been in a continuous flux of testing, repairs, upgrades, and more testing in the nine months since. The 69-meter-tall (~225 ft), 9-meter-wide (~30 ft) steel rocket was severely damaged at least twice in April and July, requiring weeks of substantial repairs. But neither instance permanently crippled the Starship booster, and Booster 7 testing has been cautious but largely successful since the rocket’s last close call.

Following its return to the OLS [orbital launch site] in early August, Super Heavy B7 has completed six static fire tests of anywhere from one to fourteen of its 33 Raptor engines. It has almost certainly dethroned Falcon Heavy to become the most powerful SpaceX rocket ever tested. And on January 8th, 2023, SpaceX rolled the rocket back to Starbase’s orbital launch site for the seventh time. According to statements made by CEO Elon Musk and a presentation from a NASA official, the last major standalone test between Booster 7 and flight readiness is a full 33-engine static fire. Together, B7’s 33 Raptor 2 engines could produce up to 7600 tons (16.7 million lbf) of thrust at sea level, likely making Starship the most powerful rocket stage in the history of spaceflight.

I had read speculation earlier that it was impossible for SpaceX to do a full 33-engine static fire test because the OLS could not hold the rocket down. That now appears to be incorrect.

Musk’s tweet and proposed schedule should also not be taken with great seriousness. He routinely sets ambitious targets merely to keep the pace fast, even if those targets are not met.

SpaceX raises another $750 million in private investment capital

SpaceX has just completed another round of fund-raising, gaining another $750 million in private investment capital.

This additional money now means that SpaceX has raised about $10 billion in private money, most of which is being used for the development of Starship and Superheavy. When we add the $4 billion SpaceX will get from NASA for Starship, the company now has $14 billion to build this new rocket.

Billionaire Maezawa chooses his passengers for Starship lunar flight

Japanese billionaire Yusaku Maezawa yesterday announced the eight passengers he will take with him on his private Starship flight around the Moon, its launch date still not set.

The full list of ten (including the two back-up passengers) is a wide mixture of individuals with a wide range of disciplines coming from a wide range of countries. For those interested in space, the one name that stood out and was very familiar was Tim Dodd, created of Everyday Astronaut. He created a video describing his selection as well as Maezawa’s entire project, which I have embedded below:

SpaceX conducts successful static fire test of Superheavy

SpaceX today successful completed a 13-second static fire test of its Superheavy first stage booster at Boca Chica, Texas.

I have embedded the video of the test below, cued to just before ignition. The test fired eleven of the booster’s 33 engines, and appeared to go very smoothly.

The company is still moving steadily towards an orbital launch of Superheavy and Starship before the end of the year.

Superheavy prototype #7 undergoes 14 engine static fire test

SpaceX’s seventh prototype of its Superheavy first stage booster — intended to launch its Starship orbital craft on the first orbital flight — successfully completed a 10-second static fire test of 14 of its 33 engines yesterday.

I have embedded video of the test below the fold. It shows the burn repeatedly from different angles. It appears the engine test went exactly as planned, with no subsequent fires near the launch pad.

According to the article at the link, this test fire, even with only 14 engines, made this Superheavy booster the most powerful rocket on Earth, at least until tonight when NASA’s SLS launches. Once this booster fires all of its 33 Raptor-2 engines however it will then exceed SLS in power. That it hasn’t launched however makes this claim a little overstated.

Regardless, SpaceX continues to move quite smoothly towards that first orbital launch of Starship, which the company hopes to do before the end of the year.

Dennis Tito signs deal to fly on 2nd manned Starship mission around Moon

Capitalism in space: Dennis Tito, the first tourist to fly in space and now 82-years-old, has signed a deal with SpaceX for both him and his wife Akiko to fly on 2nd manned Starship mission around Moon.

His weeklong moonshot — its date to be determined and years in the future — will bring him within 125 miles (200 kilometers) of the lunar far side. He’ll have company: his wife, Akiko, and 10 others willing to shell out big bucks for the ride.

Tito won’t say how much he’s paying; his Russian station flight cost $20 million.

The couple recognize there’s a lot of testing and development still ahead for Starship, a shiny, bullet-shaped behemoth that’s yet to even attempt to reach space. “We have to keep healthy for as many years as it’s going to take for SpaceX to complete this vehicle,” Tito said in an interview this week with The Associated Press. “I might be sitting in a rocking chair, not doing any good exercise, if it wasn’t for this mission.”

The bottom line is that this deal, combined with the two other passenger Starship deals SpaceX has already signed, demonstrates that there is a solid market for Starship, even before its first launch. Expect that market to boom once the rocket begins operations.

SpaceX fully stacks Starship/Superheavy in preparation for launch

Starship about to be stacked on Superheavy

the launch tower’s chopstick arms. Click for full image.

For the first time in six months SpaceX engineers have stacked Starship prototype #24 on top of Superheavy prototype #7, with the intention of running a dress rehearsal countdown and a full static fire test of Superheavy’s 33 engines, all in preparation for the first orbital test flight before the end of this year.

According to CEO Elon Musk, Booster 7 and Ship 24 will attempt Starship’s first full-stack wet dress rehearsal (WDR) once all is in order. The prototypes will be simultaneously loaded with around 5000 tons (~11M lb) of liquid oxygen and methane propellant and then run through a launch countdown. Diverging just before ignition and liftoff, a WDR is meant to be more or less identical to a launch attempt.

…If the wet dress rehearsal goes to plan, SpaceX will then attempt to simultaneously ignite all 33 of the Raptor engines installed on Super Heavy B7, almost certainly making it the most powerful liquid rocket ever tested. Even if all 33 engines never reach more than 60% of their maximum thrust of 230 tons (~510,000 lbf), they will likely break the Soviet N-1 rocket’s record of 4500 tons of thrust (~10M lbf) at sea level. It would also be the most rocket engines ever simultaneously ignited on one vehicle. SpaceX will be pushing the envelope by several measures, and success is far from guaranteed.

Depending on the results of these tests, the stacked rocket will either require further modifications, or could even proceed directly to launch.

We are thus seeing a true race between SpaceX’s privately developed and funded rocket and NASA’s government developed and funded SLS rocket. Which will launch first? Right now the race is neck-and-neck, though that is deceiving since SpaceX began development twelve years after NASA started work on SLS. Even if SLS launches first, SpaceX will have clearly shown that private enterprise does things faster (7 years vs 18 years) and for far less money (about $9 billion vs $46 billion).

SpaceX to upgrade 2nd Kennedy launchpad for manned launches

In order to create some increased redundancy, SpaceX and NASA have agreed to upgrade the company’s second launchpad at Cape Canaveral, LC-40, so that both it and pad LC-39A can launch manned Dragon capsules.

This plan grew out of concern by NASA that the new Starship orbital launchpad was too close to LC-39A, and could possibly damage it during a launch. Should that happen, and no back-up launchpad was available, the agency would have no way to get astronauts up to ISS, since Boeing’s Starliner is not yet operational. Because of that concern, NASA made it clear that no Starship launches could occur in Florida until this issue was resolved.

The solution? Make LC-40 a manned launchpad too.

Nothing is known about the nature of the modifications that LC-40 will require. But more likely than not, NASA will require SpaceX to develop something similar to Pad 39A’s facilities. That would involve building a new crew access tower, crew access arm, escape system (39A uses baskets and ziplines), and an on-site bunker for astronauts.

It is also likely that no Starship launches at Kennedy will occur until this work is done and a manned launch from LC-40 takes place. Though this could delay Starship somewhat, I expect not significantly. Before SpaceX is ready to launch operationally in Florida, it still has to do a lot of testing and development of Starship/Superheavy in Boca Chica, work that could take several years. I also suspect that it will get the launchpad work done relatively quickly, especially if NASA agrees to pay for it.

Musk: Starship orbital attempt by November, at the latest

According to a tweet yesterday by Elon Musk, SpaceX engineers will likely have the first orbital prototypes of Starship and Superheavy ready for the orbital attempt either late in October, or by November. His full tweet:

Late next month maybe, but November seems highly likely. We will have two boosters & ships ready for orbital flight by then, with full stack production at roughly one every two months. [emphasis mine]

The highlighted words are the most significant. SpaceX is not building one rocket for test, like NASA has done with SLS. It is building an assembly line of test rockets, so that it can do a fast series of test launches plus upgrades, leading to quick and reliable operations. Should any one rocket launch fail, the company will speedily move on to the next, with little or no delay.

Should SLS fail in its first test launch sometime in the next month, NASA has no back-up. The entire program will be shattered, with no easy way to recover.

SpaceX fires seven engines on Superheavy prototype #7

Capitalism in space: SpaceX today successfully did a static fire engine test of seven engines on its Superheavy prototype #7, intended to be the lower stage of the first Superheavy/Starship orbital test.

The link takes you to the full live stream. Below I have cued that live stream to just before the test occurred. Everything seems to go as planned, with no obvious anomalies.

SpaceX continues to be moving closer and closer to that first orbital flight.

Update on SpaceX’s Starship and Superheavy

Link here. The article not only outlines the test program leading to the first launch of prototypes Starship #24 and Superheavy #7, it describes the status of later prototypes, as well as the construction of SpaceX’s Starship launch site in Florida. Key quote:

Booster 7’s gradual approach to static fire testing will allow the teams to fix issues as they test and fully mature procedures and software ahead of the long-awaited orbital flight of Starship. Should this gradual testing go without a hitch, it could culminate in one or perhaps even two 33-engine static fire tests of Booster 7 on the OLM [orbital launch mount].

Once this testing is completed and any issues found fixed, it’ll be cleared to proceed into another phase of testing: Ship 24 will then be stacked on top of Booster 7 for combined tests. This could include launch countdown simulations, an eventual full-up countdown, and a 33-engine static fire test.

SpaceX hopes to complete this by mid-next month and clear both vehicles for launch shortly after. However, as we’ve seen in the past few weeks, any issues encountered during this intense test campaign could well mean a slip to later into the year and, perhaps, into next year.

SpaceX successfully test fires all six engines on Starship prototype #24

Capitalism in space: SpaceX yesterday successfully completed for the first time an eight-second-long static fire test of all six engines on Starship prototype #24.

I have embedded video of the test below. The amount of power exhibited is quite impressive. In fact, it was so powerful it likely melted the concrete below the rocket, sending hot debris flying that caused a major brushfire.

Most likely, eight long seconds of blast-furnace conditions melted the top layer of surrounding concrete and shot a hailstorm of tiny superheated globules in almost every direction. Indeed, in almost every direction there was something readily able to burn, a fire started. In several locations to the south and west, brush caught fire and began to burn unusually aggressively, quickly growing into walls of flames that sped across the terrain. To the east, debris even made it into a SpaceX dumpster, the contents of which easily caught fire and burned for hours.

Eventually, around 9pm CDT, firefighters were able to approach the safed launch pad and rocket, but the main fire had already spread south, out of reach. Instead, they started controlled burns near SpaceX’s roadblock, hoping to clear brush and prevent the fire (however unlikely) from proceeding towards SpaceX’s Starbase factory and Boca Chica Village homes and residents.

The rocket itself came though the test unscathed, a major milestone on the path to its first orbital flight.

During a launch, the rocket would have quickly lifted off, and thus caused far less stress to the concrete on the ground. Nonetheless, this test suggests SpaceX needs to do more pad preparation for any tests of Superheavy prototype #7, which has 33 engines at its base.
