SpaceX’s first orbital Starship prototype prepares for proof tests

Published

on

Several days after SpaceX’s first orbital-class Starship prototype took a second trip to a nearby launch site, the rocket is on its way to one of two suborbital launch mounts.

Once installed on the steel structure, Starship prototype 20 (S20) will finally be ready for – at minimum – two crucial tests: a cryogenic proof and static fire. According to highway closures filed by SpaceX late last week, the first of those tests could apparently begin as early as Thursday, August 19th, potentially setting Starship S20 up to attempt at least one major milestone next week.

On August 13th, SpaceX rolled Starship S20 back to the launch site a week after the rocket was sent to the pad to be briefly stacked on top of a Super Heavy booster – an event that appears to have been something like 50% photo opportunity, 50% test objective. Neither the booster or ship were fully complete at the time and both ultimately required at least another week or two of outfitting and plumbing to be ready for ground testing – let alone flight. Aspirationally, the same pair – Ship 20 and Booster 4 – could be the first to attempt a true orbital Starship launch sometime later this year.

Since its second rollout, Ship 20 has more or less stayed in one place as workers continuously swarmed about the rocket on boom and scissor lifts. Over the last four days, not much has visually changed save for the installation of a handful of heat shield tiles, but the focus clearly centered around the Starship’s ‘raceway’ – a clutch of plumbing and wiring that runs most of the length of the vehicle’s back. Virtually all rockets have them and Starship is no different with a raceway packed with avionics wire runs, plumbing for propellant loading, and smaller lines for pressurization and hydraulics.

While it’s not entirely clear what specific work has been done over the last few days or why it wasn’t done back at the build site, where CEO Elon Musk himself has said such tasks are more easily done, it’s clear that Starship S20 does have a more refined raceway than any ship before it. In recent days, SpaceX has also begun to install structural elements that strongly imply that S20 will be the first Starship to receive a raceway aerocover – not unlike those on Falcon boosters – to protect its external wiring and plumbing in flight.

Regardless, once Starship S20 is installed on one of SpaceX’s two suborbital launch mounts, the vehicle will most likely be prepared for a routine cryogenic proof test. To pass, Starship will need to survive significant thermal and mechanical stress as its tanks are filled with supercool liquid nitrogen and pressurized to at least 6 bar (~90 psi). At this point, a Starship prototype hasn’t failed a cryo proof in more than a year, so the test should be fairly routine.

Curiously, after spending weeks modifying Mount B with a series of hydraulic rams meant to simulate the thrust of Ship 20’s six Raptor engines during its cryo proof(s), SpaceX removed all of that extra hardware just prior to the Starship’s second rollout and now-imminent installation on said mount. Regardless of why, that decision likely means that Starship S20 will move directly to static fire testing once it passes cryo proofing. Given that Ship 20 appears to be on track to be the first Starship prototype of any kind to fire more than three Raptors at a time, that static fire campaign will likely be somewhat cautious, possibly beginning with just 1-3 engines and then moving to four, five, or straight to six.

SpaceX could also throw caution to the wind (not implausible as evidenced by the removal of Pad B’s unused thrust rams) and install and attempt to fire all six Raptors immediately after Ship 20 completes a cryo proof. Based on road closures filed by SpaceX, that testing could begin as early as 5pm to 11pm CDT on Thursday, August 19th. A backup window is also scheduled from 6am to 12pm CDT on August 20th.

X’s Community Notes pilot seeks to bridge perspectives by introducing an experimental feature to identify posts liked by diverse viewpoints. Announced by Elon Musk’s X, the initiative builds on the success of Community Notes, which highlights agreement among users who typically disagree.

Starting June 05, a select group of Community Notes contributors, representing a broad spectrum of perspectives, will encounter a new callout within the platform. “The callout shows based on early and limited Like signals on the post,” X explained.

Contributors can rate and provide feedback on these posts, aiding the development of an open-source algorithm to identify content that resonates across differing viewpoints. The pilot aims to uncover ideas, insights, and opinions that foster unity, addressing the often-divided nature of online discourse.

“People often feel the world is divided, yet Community Notes shows people can agree, even on contentious topics,” X noted. The new feature builds on years of user requests to extend Community Notes’ approach to posts, recognizing those liked by people who would normally disagree. By highlighting such content, X hopes to motivate users to share ideas that resonate broadly, potentially driving meaningful dialogue.

The pilot follows X’s transparent development process, similar to how Community Notes was refined. “Following the path we used to develop Community Notes, we’re building in public with a small pilot so that this concept can be shaped by the people,” X stated. The initiative will rely on contributor feedback to iterate and refine the algorithm, ensuring it effectively identifies posts that bridge perspectives.

This experimental feature underscores X’s commitment to fostering constructive online conversations. By leveraging early “Like” signals and contributor input, X aims to amplify content that transcends ideological divides.

“Ultimately, it could help move the world forward in ways that the people want,” X added, emphasizing the potential for this tool to promote unity and understanding.

As X rolls out this pilot, the platform invites its community to shape its evolution, much like the iterative process that has made Community Notes a hallmark of collaborative fact-checking. The initiative could redefine how social media platforms highlight shared values, paving the way for more inclusive and impactful discussions.

X account with 184 followers inadvertently saves US space program amid Musk-Trump row

Needless to say, the X user has far more than 184 followers today after his level-headed feat.

An X user with 184 followers has become the unlikely hero of the United States’ space program by effectively de-escalating a row between SpaceX CEO Elon Musk and President Donald Trump on social media.

Needless to say, the X user has far more than 184 followers today after his level-headed feat.

A Near Fall

During Elon Musk and Donald Trump’s fallout last week, the U.S. President stated in a post on Truth Social that a good way for the United States government to save money would be to terminate subsidies and contracts from the CEO’s companies. Musk responded to Trump’s post by stating that SpaceX will start decommissioning its Dragon spacecraft immediately. 

Musk’s comment was received with shock among the space community, partly because the U.S. space program is currently reliant on SpaceX to send supplies and astronauts to the International Space Station (ISS). Without Dragon, the United States will likely have to utilize Russia’s Soyuz for the same services—at a significantly higher price.

X User to the Rescue

It was evident among X users that Musk’s comments about Dragon being decommissioned were posted while emotions were high. It was then no surprise that an X account with 184 followers, @Fab25june, commented on Musk’s post, urging the CEO to rethink his decision. “This is a shame this back and forth. You are both better than this. Cool off and take a step back for a couple days,” the X user wrote in a reply.

Much to the social media platform’s surprise, Musk responded to the user. Even more surprising, the CEO stated that SpaceX would not be decommissioning Dragon after all. “Good advice. Ok, we won’t decommission Dragon,” Musk wrote in a post on X.

Not Planned, But Welcomed

The X user’s comment and Musk’s response were received extremely well by social media users, many of whom noted that @Fab25june’s X comment effectively saved the U.S. space program. In a follow-up comment, the X user, who has over 9,100 followers as of writing, stated that he did not really plan on being a mediator between Musk and Trump. 

“Elon Musk replied to me. Somehow, I became the accidental peace broker between two billionaires. I didn’t plan this. I was just being me. Two great minds can do wonders. Sometimes, all it takes is a breather. Grateful for every like, DM, and new follow. Life’s weird. The internet’s weirder. Let’s ride. (Manifesting peace… and maybe a Model Y.)” the X user wrote.

Tesla tops Cathie Wood’s stock picks, predicts $2,600 surge

Tesla’s future lies beyond cars—with robotaxis, humanoid bots & AI-driven factories. Cathie Wood predicts a 9x surge in 5 years.

Cathie Wood shared that Tesla is her top stock pick. During Steven Bartlett’s podcast “The Diary Of A CEO,” the Ark Invest founder highlighted Tesla’s innovative edge, citing its convergence of robotics, energy storage, and AI.

“Because think about it. It is a convergence among three of our major platforms. So, robots, energy storage, AI,” Wood said of Tesla. She emphasized the company’s potential beyond its current offerings, particularly with its Optimus robots.

“And it’s not stopping with robotaxis; there’s a story beyond that with humanoid robots, and our $2,600 number has nothing for humanoid robots. We just thought it’d be an investment, period,” she added.

In June 2024, Ark Invest issued a $2,600 price target for Tesla, which Wood reaffirmed in a March Bloomberg interview, projecting the stock to reach this level within five years. She told Bartlett that Tesla’s Optimus robots would drive productivity gains and create new revenue streams.

Elon Musk echoed Wood’s optimism in a CNBC interview last month.

“We expect to have thousands of Optimus robots working in Tesla factories by the end of this year, beginning this fall. And we expect to scale Optimus up faster than any product, I think, in history to get to millions of units per year as soon as possible,” Musk said.

Tesla’s stock has faced volatility lately, hitting a peak closing price of $479 in December after President Donald Trump’s election win. However, Musk’s involvement with the White House DOGE office triggered protests and boycotts, contributing to a stock decline of over 40% from mid-December highs by March.

The volatility in Tesla stock alarmed investors, who urged Musk to refocus on the company. In a May earnings call, Musk responded, stating he would be “scaling down his involvement with DOGE to focus on Tesla.” Through it all, Cathie Wood and Ark Invest maintained their faith in Tesla. Wood, in particular, predicted that the “brand damage” Tesla experienced earlier this year would not be long term.

Despite recent fluctuations, Wood’s confidence in Tesla underscores its potential to redefine industries through AI and robotics. As Musk shifts his focus back to Tesla, the company’s advancements in Optimus and other innovations could drive it toward Wood’s ambitious $2,600 target, positioning Tesla as a leader in the evolving tech landscape.
