Elon Musk: SpaceX’s first orbital Starship launch “highly likely” in Q1 2023

Published

on

SpaceX’s first Starship orbital launch mount (OLM) appears to have passed a busy week of stress-testing, clearing the way for the company to transport a finished Super Heavy booster to the pad.

Using the same launch mount, that Starship booster is expected to attempt to complete some of the riskiest and most challenging tests SpaceX has ever conducted at its Starbase rocket development facilities. The schedule for that testing is unclear, but after an unusually drawn-out period of qualification testing, Super Heavy Booster 7 (B7) could soon attempt a full static fire test of all 33 of its Raptor 2 engines. Either before or after that crucial test, SpaceX is also expected to install Ship 24 (S24) on top of Super Heavy B7 for Starship’s first full-stack “wet dress rehearsal.”

Ultimately, if that testing produces the results SpaceX wants to see, CEO Elon Musk says that Starship could attempt its first orbital launch as early as late February or March 2023.

Booster 7

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 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 (OLS) 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.

Ship 24

Starship prototype S24’s path has been a bit less rocky. The ship has needed some less obvious repairs, particularly right after its first tests in May 2022. Since August 2022, Ship 24 has completed three static fire tests – all seemingly successful. Most importantly, one of those tests ignited all six of S24’s Raptor engines, potentially qualifying it for an orbital launch attempt. Most recently, SpaceX completed a series of mysterious repairs, replaced and static-fired one of S24’s engines, and removed the Starship from its test stand.

With Booster 7 now awaiting installation on Starbase’s orbital launch mount and Ship 24 near-simultaneously removed from its test stand, it appears that SpaceX may attempt a different test before Super Heavy’s full static fire. Instead, SpaceX could start by stacking Ship 24 and Booster 7 and conducting a full-stack wet dress rehearsal (WDR) before shifting focus to Booster 7’s riskier static fire.

A wet dress rehearsal is a routine test conducted before a rocket launch and is generally designed to simulate every aspect of a launch save for engine ignition and liftoff. Most importantly, that involves fully filling the rocket with propellant and passing all of the checks the same rocket would need to pass to be cleared for launch. For Starship, the largest rocket ever built, a full propellant load means filling both stages with an extraordinary ~5000 tons of liquid oxygen and liquid methane propellant. SpaceX also needs to fill the rocket fast enough to keep that propellant supercool, which increases its density and overall performance.

The first full-stack WDR will thus test Starbase’s launch facilities just as much as Booster 7 and Ship 24. SpaceX has conducted many several Starship WDRs, but not with Ship 24. It’s also never fully filled a Super Heavy booster with real propellant, let alone both stages at once. It’s likely that issues will be discovered as SpaceX pushes the envelope, likely requiring multiple attempts.

OLS

In the spirit of caution, SpaceX has even taken the unusual step of stress-testing Starship’s orbital launch mount with a custom jig. In the first week of 2023, SpaceX used that jig to load pairs of the OLM’s 20 hold-down clamps with hundreds of tons of ballast, ensuring that they can withstand the immense weight of a fully-fueled Starship. Proof tests of Super Heavy B4 and B7 have likely subjected the OLM to 2000+ tons of force, but a full Starship will weigh more than double the maximum weight the OLM has experienced to date.

Plenty of risk remains and SpaceX is trading speed for caution, but this extra-cautious step has likely reduced the risk of the launch mount’s structure failing during wet-dress and static fire testing. According to Musk, SpaceX has a “real shot” at preparing Starship for a “late February” orbital launch attempt. Nonetheless, Musk also implied that a full-stack WDR and 33-engine static fire would “probably” be completed “in a few weeks” in September 2022. What is clear is that SpaceX is more committed than ever before to avoiding a catastrophic failure during Starship’s first orbital launch attempt.

SpaceX Starship Flight 10: What to expect

SpaceX implemented hardware and operational changes aimed at improving Starship’s reliability.

SpaceX is preparing to launch the tenth test flight of its Starship vehicle as early as Sunday, August 24, with the launch window opening at 6:30 p.m. CT. 

The mission follows investigations into anomalies from earlier flights, including the loss of Starship on its ninth test and a Ship 36 static fire issue. SpaceX has since implemented hardware and operational changes aimed at improving Starship’s reliability.

Booster landing burns and flight experiments

The upcoming Starship Flight 10 will expand Super Heavy’s flight envelope with multiple landing burn trials. Following stage separation, the booster will attempt a controlled flip and boostback burn before heading to an offshore splashdown in the Gulf of America. One of the three center engines typically used for landing will be intentionally disabled, allowing engineers to evaluate whether a backup engine can complete the maneuver, according to a post from SpaceX.

The booster will also transition to a two-engine configuration for the final phase, hovering briefly above the water before shutdown and drop. These experiments are designed to simulate off-nominal scenarios and generate real-world data on performance under varying conditions, while maximizing propellant use during ascent to enable heavier payloads.

Starship upper stage reentry tests

The Starship upper stage will attempt multiple in-space objectives, including deployment of eight Starlink simulators and a planned Raptor engine relight. SpaceX will also continue testing reentry systems with several modifications. A section of thermal protection tiles has been removed to expose vulnerable areas, while new metallic tile designs, including one with active cooling, will be trialed.

Catch fittings have been installed to evaluate their thermal and structural performance, and adjustments to the tile line will address hot spots observed on Flight 6. The reentry profile is expected to push the structural limits of Starship’s rear flaps at maximum entry pressure.

SpaceX says lessons from these tests are critical to refining the next-generation Starship and Super Heavy vehicles. With Starfactory production ramping in Texas and new launch infrastructure under development in Florida, the company is pushing to hit its goal of achieving a fully reusable orbital launch system.

Elon Musk takes aim at Bill Gates’ Microsoft with new AI venture “Macrohard”

It is quite an appropriate name for a company that’s designed to rival Microsoft.

Elon Musk has set his sights on Microsoft with a new company called “Macrohard,” a software venture tied to his AI startup, xAI. 

Musk described the project as a “purely AI software company” that’s designed to generate hundreds of specialized coding and generative AI agents that could one day simulate products from companies like Microsoft entirely through artificial intelligence.

Macrohard‘s Purpose

Musk announced Macrohard on Friday, though xAI had already registered the trademark with the US Patent Office a few weeks ago, as noted in a PC Mag report. Interestingly enough, this is not the first time that Musk has mentioned such an initiative.

Just last month, he stated that xAI was “creating a multi-agent AI software company, where Grok spawns hundreds of specialized coding and image/video generation/understanding agents all working together and then emulates humans interacting with the software in virtual machines until the result is excellent.”

At the time, Musk stated that “This is a macro challenge and a hard problem with stiff competition,” hinting at the venture’s “Macrohard” moniker. A few years ago, Musk also posted “Macrohard >> Microsoft” on X.

Powered by xAI and Colossus

Macrohard appears to be closely linked to xAI’s Colossus 2 supercomputer project in Memphis. Musk has confirmed plans to acquire millions of Nvidia GPUs, joining rivals such as OpenAI and Meta in a high-stakes race for AI computing power. Colossus is already one of the most powerful supercomputer clusters in the world, and it is still being expanded.

xAI is only a couple of years old, having been founded in March 2023. During its Engineering Open House event in San Francisco, Elon Musk highlighted that the company’s speed will be its primary competitive edge. “No SR-71 Blackbird was ever shot down and it only had one strategy: to accelerate,” Musk said.

Elon Musk tends to use social media platform X as his personal platform to express himself, so much so that critics tend to allege that the CEO is no longer serious about his numerous companies. 

As per Musk, he is still very much in wartime CEO mode, despite all the jokes and fun posts about Ani on X. 

Elon Musk leads several prolific companies, much more than the average CEO. And while Tesla is the only publicly traded entity that he currently leads, Musk is so visible that everyone across the internet pretty much has a strong opinion of him one way or another. For his longtime supporters and followers, however, what truly matters is if Musk is locked in.

Considering that Elon Musk’s feed on X has recently been filled with AI imagery, a good portion of which involve AI-rendered women, some X users have expressed concerns that the CEO may be losing focus once more. Musk responded to one such user by highlighting his very busy schedule and his numerous active projects. 

Needless to say, Elon Musk is still locked in. He is still in “wartime CEO” mode.

As per the CEO, even his recent AI posts about AI are “part of a broader vision and strategy.” He also highlighted that SpaceX’s Starship Flight 10 is launching in a few days, xAI’s Grok 5 is starting its training next month, and Tesla’s Autopilot V14 is also coming next month. As per Musk, “long-term strategy is compelling.”

Elon Musk’s comments are quite accurate. While he may seem to spend all his time on X, after all, he is very much still neck-deep in all his companies’ projects. There is a reason why Musk became known as a visionary, and a lot of it is because he really is intimately involved in all of his companies’ projects.
