SpaceX looks to launch space tourists to record heights
SpaceX has signed an agreement with a space tourism company that could see its Crew Dragon spacecraft take space tourists to heights unmatched by astronauts in half a century.
On Tuesday, February 18th, Space Adventures announced the agreement, revealing that it is now officially looking for wealthy private customers interested in launching to orbit on a SpaceX rocket and spacecraft. Known as Crew Dragon, that spacecraft is perhaps just two or three months away from SpaceX’s inaugural astronaut launch, in which two NASA astronauts will be sent into orbit to rendezvous and dock with the International Space Station (ISS) before returning to Earth after several weeks or months in space.
Founded in 1998, while Space Adventures has a slightly checkered past and has been more or less inactive for more than a decade, the company did manage to arrange eight separate spaceflights for seven private customers between 2001 and 2009. All flights previously arranged were done so through Russian space agency Roscosmos with Soyuz rockets and spacecraft and involved approximately week-long visits to the International Space Station (ISS), where the private astronauts – all multimillionaires and billionaires – mainly observed routine ISS operations and assisted with science experiments. With SpaceX’s Falcon 9 and Crew Dragon, Space Adventures hopes to soon offer orbital tourists an option that keeps all operations in the United States.
As noted, it must be stated that the February 18th agreement doesn’t actually mean that private customers will definitively launch into orbit in SpaceX’s Crew Dragon spacecraft. Instead, it serves as a semi-contractual confirmation that the spaceflight company is officially willing and ready to support such a mission in the event that Space Adventures is able to secure enough customers to purchase the necessary launch services. While not out of the question, that will be no easy feat.
Thankfully, several aspects of this new agreement should work in SpaceX and Space Adventures’ favor. As a unique ‘free-flying’ mission, Crew Dragon and its space tourists would not actually rendezvous with the ISS – instead serving as its own miniature outpost in Low Earth Orbit (LEO) for several days. Relative to SA’s past tourist flights to the ISS, this will save a large portion of the time and cost associated with both training civilians for spaceflight and ISS operations and working with NASA and Roscosmos to arrange the complex mission.
Aside from simplifying the training and bureaucracy involved in orbital tourism, the fact that Space Adventures’ newest proposal will have no affiliation or involvement with NASA or Roscosmos also means that there’s nothing preventing SpaceX from using a flight-proven Falcon 9 booster and Crew Dragon capsule on its space tourist launch. By combining flight-proven hardware with a space station-free mission profile, SpaceX could theoretically cut the overall flight’s cost by tens or even hundreds of millions of dollars.
According to public analyses performed over the last few years by auditors and researchers, SpaceX Crew Dragon launches will likely cost NASA around $400 million each, while a comparable Boeing Starliner mission will cost the space agency at least $650 million. The SpaceX figure is, however, predicated upon the production of a brand new Falcon 9 rocket and Crew Dragon spacecraft for each launch and includes costs associated with any processing or operations involving NASA teams and facilities.
As noted above, the use of a thoroughly flight-proven Falcon 9 booster and Crew Dragon capsule could dramatically cut the cost of private astronaut launches relative to the NASA baseline. It’s conceivable that – having effectively amortized the cost of the spacecraft and booster with a NASA astronaut launch – such a private mission’s price could be little more than the cost of building a new Falcon upper stage and Crew Dragon trunk, as well as booster/capsule refurbishment and general operations. Conservatively, the ultimate price SpaceX offers or offered Space Adventures could thus be as low as $100-200 million per launch.
Space Adventures says it could support as many as four space tourists on one flight, translating to a cost of $25-50 million per person if all seats are filled. This would compare reasonably well with the $20-50 million it typically charged its seven orbital tourism customers. That is still a vast sum of money and cuts the pool of potential customers to perhaps a few tens of thousands of people worldwide. Nevertheless, Google co-founder Sergey Brin (and possibly others) is on a sort of waiting list (requiring a $5 million deposit) for future orbital Space Adventures flights, giving the company at least one strong prospective customer.
Thanks to skipping a space station rendezvous, perhaps the single biggest selling point of the mission is that Falcon 9 and Crew Dragon could potentially send space tourists higher than ever before – to an altitude only certain NASA Apollo and Gemini astronauts can claim to have surpassed. Space Adventures specifically notes this on its website, stating that prospective space tourists could reach an altitude that only Gemini 11 astronauts have surpassed while remaining in Earth orbit.
Gemini 11 astronauts reached an of apogee around 850 miles (1350 km) while still in Earth orbit – a record that stands today. Neither Space Adventures or SpaceX have specifically stated how high an unmodified Falcon 9 and Crew Dragon to launch private astronauts, but the implication is that the view would be comparable to – or even better than – what the Gemini 11 crew saw back in 1966. Regardless, it’s safe to say that if SpaceX and Space Adventures’ new space tourism effort is greeted with healthy demand, we’ll be shortly entering a new era of private spaceflight. Crew Dragon’s first private astronaut mission is tentatively scheduled to launch as early as late-2021 or early-2022.

Tesla (NASDAQ: TSLA) is set to hold its Earnings Call for the first quarter of 2026 on Wednesday, and there are a lot of interesting things that are swirling around in terms of speculation from investors.
With the company’s executives, including CEO Elon Musk, answering a handful of questions that investors submit through the Say platform, fans want to know a lot of things about a lot of things.
These five questions come from Retail Investors, who are normal, everyday shareholders:
- When will we have the Optimus v3 reveal? When will Optimus production start, since we ended the Model S and Model X production earlier than mid-year? What’s the expected Optimus production rate exiting this year? What are the initial targeted skills?
- What milestones are you targeting for unsupervised FSD and Robotaxi expansion beyond Austin this year, and how will that drive recurring revenue?
- How will Hardware 3 cars reach Unsupervised Full Self-Driving?
- When do you expect Unsupervised Full Self-Driving to reach customer cars?
- When will Robotaxi expand past its current limited rollout?
Additionally, these are currently the three questions that are slated to be answered by Institutional Firms, which also answer a handful of questions during the call:
- Now that FSD has been approved in the Netherlands and is expected to launch across Europe this summer, can you discuss your Robotaxi strategy for the region?
- What enabled you to finish the AI5 tapeout early and were there any changes to the original vision? Last week, Elon said AI5 will go into Optimus and the Supercomputer, but one month ago said it would go into the Robotaxi. Has AI5 been dropped from the vehicle roadmap?
- Given the recent NHTSA incident filings, can you update us on the Robotaxi safety data? If safety validation remains the primary bottleneck, why not deploy thousands of vehicles to accelerate the removal of the safety driver?
The questions range through every current Tesla project, including FSD expansion and Optimus. However, many of the answers we will get will likely be repetitive answers we’ve heard in the past.
This is especially pertinent when the questions about when Unsupervised FSD will reach customer cars: we know Musk will say that it will happen this year. Is Tesla capable of that? Maybe. But a more transparent answer that is more revealing of a true timeline would be appreciated.
Hardware 3 owners are anxiously awaiting the arrival of FSD v14 Lite, which was promised to them last year for a release sometime this year.
The Earnings Call is set to take place on Wednesday at market close.

Elon Musk reveals shocking Tesla Optimus patent detail
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
Elon Musk revealed a shocking detail on the Tesla Optimus patent that was revealed last week. Despite it being made public for the first time, Musk said the company has already moved on from the design, an incredible truth about the development of new technology: things move fast.
Musk dropped a bombshell about the Tesla Optimus humanoid robot hand patent that was released last week. Musk, candidly replying to a post late at night on X, revealed that what is a new technology to many fans and insiders is actually old news to those developing the tech directly.
“We already changed the design,” Musk said. “This one didn’t actually work.”
We already changed the design. This one didn’t actually work.

Patents, after all, are often viewed as blueprints for future products. Yet Musk revealed that the rolling contact mechanism—intended to provide smooth, low-friction articulation in the fingers—had already been scrapped after real-world testing exposed its shortcomings.
What looked promising on paper and in simulations failed to deliver the reliability required for a robot expected to handle delicate tasks like folding laundry, assembling electronics, or assisting in factories and homes.
The hand has been one of the biggest challenges for Tesla engineers since Optimus development started years ago. Musk has said that there is not enough recognition for how incredible and useful the human hand is, and designing one for a humanoid robot has been the biggest challenge of all.
Tesla is stumped on how to engineer this Optimus part, but they’re close
This moment underscores the persistent engineering hurdles in achieving reliable humanoid hand dexterity. Human fingers are marvels of evolution: 27 bones, intricate tendons, ligaments, and a network of sensors working in perfect harmony. Replicating that in metal and silicon is extraordinarily difficult.
Rolling contacts promised reduced wear and precise motion, but testing likely revealed issues with durability under repeated stress, grip stability on varied surfaces, or the micro-precision needed for fine motor skills.
These aren’t minor tweaks, but instead they represent fundamental challenges that have plagued robotics teams for decades. Even advanced competitors struggle here—hands remain the Achilles’ heel of most humanoids because the margin for error is razor-thin.
A fraction of a millimeter off, and a robot drops a glass or fails to button a shirt.
What makes Musk’s reply remarkable is how it signals Tesla’s direct communication style on prototype limitations. While many companies guard failures behind glossy marketing and vague timelines, Tesla openly shares setbacks.
Musk was forthcoming about the failure of this recent design. This transparency builds trust with investors, engineers, and fans. It shows Tesla treats Optimus development like true science: rapid iteration, rigorous testing, and zero tolerance for hype that doesn’t match reality.
The disclosure from Musk also highlights Tesla’s blistering pace of development. By the time the patents are published, which is often over a year after the initial filing, the technology has already evolved.
Optimus is far from a static product, and it’s a living project advancing weekly.
In the high-stakes race for general-purpose robots, Tesla’s approach stands out. Admitting a finger-joint design “didn’t actually work” isn’t a weakness—it’s confidence.
True innovation demands confronting failure head-on, and Musk just reminded the world that Optimus is being engineered that way. The next version of those hands is already in testing, and it will be better because Tesla isn’t afraid to say what didn’t work.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.
Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.
Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.
