Watch SpaceX’s Inspiration4 mission launch four private astronauts live [webcast]
Update: SpaceX, Falcon 9, Crew Dragon, the crew, and the weather remain on track for the company’s historic Inspiration4 mission, which is set to become the first dedicated orbital space tourism launch in history.
SpaceX has begun more than four hours of live coverage for the mission, which remains on track to launch no earlier than just before 8:03 pm EDT (00:03 UTC). Tune in below to watch the launch live!
In less than 12 hours, SpaceX will kick off a more than four-hour webcast covering Crew Dragon’s historic Inspiration4 mission – set to be the world’s first all-private orbital astronaut launch and the highest private citizens have ever flown.
Safely tucked inside a once-flown orbital Dragon capsule and riding on a twice-flown Falcon 9 booster, the latter a first for SpaceX, Inspiration4’s approximately five-hour launch window is scheduled to open just before 8:03 pm EDT on Wednesday, September 15th (00:03 UTC 16 Sept). Barring weather or technical delays (or clouds in general), a liftoff ~35 minutes after sunset could produce spectacular views for anyone watching from the ground as Falcon 9 and its immense exhaust plume ascend back into sunlight.
No matter the view, though, Inspiration4 will be a milestone both for SpaceX, spaceflight, and orbital tourism as a whole.
The mission will both be SpaceX’s first private astronaut launch of any kind and the first all-private orbital astronaut launch in history. In a single mission, SpaceX will singlehandedly boost the number of private astronauts that have reached orbit by 50% – a feat only eight other people have achieved. If all goes according to plan, it will also be the first time ever that private citizens have successfully flown to orbit and back on or in a flight-proven rocket or flight-proven spacecraft.
According to SpaceX, Falcon 9 will launch Crew Dragon to an apogee of around 575 km (~357 mi) – more than a third higher than the ISS, the highest humans have flown since 2009, and the highest altitude ever reached by private astronauts. With Inspiration4, SpaceX will also launch astronauts on a twice-flown Falcon 9 booster and simultaneously operate three Dragon spacecraft in orbit for the first time ever, pushing the company’s own technical abilities forward.

Despite the myriad impressive firsts Inspiration4 is set to mark, one thing is certain: it won’t be the last time private astronauts head to (real) space on a SpaceX spacecraft. Already, SpaceX has contracts from Axiom Space for four dedicated private launches to the International Space Station in 2022 and 2023, each carrying up to four private astronauts. Space Adventures – responsible for organizing all eight other non-SpaceX private orbital astronaut launches in history – also has plans to launch a private crew of four to unprecedented heights, though it’s unclear if the mission has secured any customers.

In an official Q&A held on Tuesday, Benji Reed – SpaceX director of Dragon mission management – said that the company’s “Dragon manifest is getting busier by the minute” with “a growing backlog of commercial astronaut mission.” Reed also expects SpaceX to soon be capable of a minimum of 4-6 Dragon launches annually. Axiom-1, the first fully private astronaut mission to the International Space Station (ISS), is scheduled to launch no earlier than January 2022.
As for Inspiration4, Jared Isaacman, Sian Proctor, Haley Arceneaux, and Chris Sembroski will spend a bit less than three days in orbit and are expected to perform a few small science experiments, take plenty of photos, and host a couple live events over the course of the mission. They’ll also get to take advantage of Crew Dragon’s ‘cupola’ – designed specifically by SpaceX for Inspiration4 and set to be the largest window ever flown in space. A small camera inside the nosecone that will protect that window during ascent and reentry will hopefully allow the crew to take self-portraits with Earth as a spectacular backdrop.


If all goes according to plan, Dragon will reenter and return its private astronauts to Earth around 7pm EDT on Saturday, September 18th. SpaceX is expected to provide live coverage of Inspiration4’s launch and reentry and the launch webcast will begin around 4pm EDT (20:00 UTC), four hours before liftoff.

SpaceX wants to catch Starship for launch 14, Elon Musk says
Just hours after Starship Flight 13 achieved a successful soft splashdown of its upper stage in the Indian Ocean on July 24, Elon Musk announced an ambitious next step for the company’s next launch of the rocket.
“Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on [the] next flight,” the SpaceX CEO posted on X on Friday.
That “next flight” is expected to be Flight 14. The plan involves returning the Starship upper stage, commonly called the “ship,” to the Starbase launch tower in Texas and catching it mid-air using the same mechanical “chopsticks” arms that have already proven themselves with the Super Heavy booster.

A successful catch would mark the first time an orbital-class upper stage has been recovered this way, advancing SpaceX’s goal of full and rapid reusability for the entire vehicle.
SpaceX has already demonstrated the tower-catch technique multiple times with Super Heavy. The first successful catch came on Flight 5 in October 2024, when Booster 12 was plucked from the sky by the Mechazilla arms. Subsequent flights, including those involving Boosters 14 and 15, repeated the feat. Several of those recovered boosters were later inspected, refurbished, and flown again, proving the system’s viability for quick turnaround.
Traditional reusable rockets, such as SpaceX’s own Falcon 9 or Blue Origin’s New Shepard, land on legs either on land or droneships. Rocket Lab has recovered its small Electron first stages by helicopter, but those are far lighter vehicles.
SpaceX Starship just nailed something it’s never done before
The China Academy of Launch Vehicle Technology (CALT), a subsidiary of the China Aerospace Science and Technology Corp. (CASC), completed a catch of its booster on July 10. They are the only entity besides SpaceX to attempt and complete the feat.
Flight 13 provided encouraging data. The ship executed a controlled reentry, flipped, and soft-landed intact in the ocean after deploying Starlink satellites, offering the first clear post-splashdown views of an undamaged heat shield. The Super Heavy booster, meanwhile, experienced a harder splashdown in the Gulf of Mexico.
Musk has previously stressed that ship catches would only follow multiple successful soft ocean landings to minimize risk of debris over land.
If Flight 14 succeeds, SpaceX would take a major stride toward routine, rapid reuse of both stages—critical for lowering launch costs and supporting ambitious plans for lunar and Mars missions. For now, teams are reviewing the Flight 13 data. Should everything check out, the next Starship flight could deliver one of the most spectacular recoveries in aerospace history.

Tesla to open source Model S and Model X designs and software
In a move echoing its earlier commitment to open innovation, Tesla CEO Elon Musk announced recently that the company plans to make the design and software of its Model S and Model X fully open source.
This follows the same approach Tesla took with its original Roadster, releasing all available design, engineering, and diagnostic materials in November 2023 so that “whatever we have, you now have.”
Just as Tesla made the original Roadster design & software open source, we plan to do the same with Model S & X
— Elon Musk (@elonmusk) July 24, 2026
The Model S, introduced in 2012, was Tesla’s first mass-produced vehicle and a groundbreaking luxury electric sedan. It offered impressive range, rapid acceleration, and over-the-air software updates that redefined expectations for electric cars.
The Model X, launched in 2015, built on that foundation as a high-performance electric SUV notable for its distinctive falcon-wing doors, spacious interior, and advanced safety features. Both models served as flagships that helped establish Tesla as a leader in the EV industry and popularized long-range battery-electric vehicles.
Production of the Model S and Model X was wound down earlier in 2026, with manufacturing ending in the second quarter. Tesla redirected the Fremont factory space previously used for these vehicles toward higher-priority projects, including Optimus humanoid robots and the Cybercab autonomous vehicle.
By the time of Musk’s open-source announcement, custom orders had closed and only remaining inventory was available.
Open-sourcing the designs and software offers several clear advantages. Owners of these aging but still capable vehicles gain better access to technical documentation, diagnostic tools, and software resources, making independent repairs and modifications easier and more affordable.
Independent repair shops and third-party specialists can support the large existing fleet without relying solely on Tesla’s service network. Enthusiasts and engineers can study real-world implementations of Tesla’s battery, powertrain, and software systems, potentially accelerating broader industry progress in electric mobility.
The step aligns with Tesla’s 2014 patent pledge and its overall mission to advance sustainable transport by sharing hard-won knowledge rather than locking it behind proprietary walls.
By releasing these materials now that the models have left production, Tesla ensures continued support for its early adopters while freeing internal resources for future technologies. The open-source release of the original Roadster already enabled simulations, community projects, and deeper technical understanding.
Extending that practice to the Model S and Model X should deliver similar benefits on a larger scale, helping keep these influential vehicles relevant and repairable for years to come

Tesla flexes incredible Robotaxi metric that skeptics will hate
Tesla flexed one incredible Robotaxi metric during the Q2 Earnings Call that skeptics have to hate to hear. The company’s platform has already driven more than 380,000 miles of unsupervised ride-hailing across several states with no notable incidents.
During the company’s Q2 Earnings Call on Wednesday, Vice President of AI, Ashok Elluswamy, said:
“First of all, I’d like to state that the Robotaxi program has been operating extremely well. Especially in terms of safety, the program has had an impeccable safety record. We have driven more than 380,000 miles of unsupervised Robotaxi, now across six cities in two different states. We have had zero notable incidents. Any reports have been of other actors impacting us when we were stationary. I like to emphasize how safe the operation has been so far. Zero notable incidents over 380,000 miles.”
Elluswamy’s claim over Robotaxi miles is a significant milestone for Tesla in the grand scheme, especially considering this is a sizeable number of miles without any incident.

— Tesla (@Tesla) July 22, 2026
Tesla’s self-driving approach is much different than that of other companies. Tesla has maintained that vision is the only thing needed to have a solid and effective self-driving suite. Many self-driving companies utilize things like LiDAR, sensors, and other elements to improve performance, but Elluswamy sent a jab at those who believe it’s needed.
“Historically, the so-called experts have always claimed that you need LiDARs, radars, HD maps, and the entire kitchen sink to drive safely. Here we show that such is not true. You can have safe, comfortable, and affordable autonomy with just cameras. This record should be a huge validation of Tesla’s entire AI approach.”
The feat of accumulating this many miles without any driver behind the wheel is impressive. The thing is, Tesla is also doing this across several different locations, with varying traffic rules, pedestrian levels, weather patterns, and other important factors.
While Tesla is not ready to roll out an unsupervised platform completely, it is a slow but steady indication that the company is well on its way to figuring things out.
The company’s attitude toward expansion is slow, safe, and controlled, and despite this huge milestone, it will still be some time until we see Tesla truly unleash unsupervised rides more aggressively.
