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.
I asked about future non-government missions for SpaceX:

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.

Tesla’s Elon Musk: 10 billion miles needed for safe Unsupervised FSD
As per the CEO, roughly 10 billion miles of training data are required due to reality’s “super long tail of complexity.”
Tesla CEO Elon Musk has provided an updated estimate for the training data needed to achieve truly safe unsupervised Full Self-Driving (FSD).
As per the CEO, roughly 10 billion miles of training data are required due to reality’s “super long tail of complexity.”
10 billion miles of training data
Musk comment came as a reply to Apple and Rivian alum Paul Beisel, who posted an analysis on X about the gap between tech demonstrations and real-world products. In his post, Beisel highlighted Tesla’s data-driven lead in autonomy, and he also argued that it would not be easy for rivals to become a legitimate competitor to FSD quickly.
“The notion that someone can ‘catch up’ to this problem primarily through simulation and limited on-road exposure strikes me as deeply naive. This is not a demo problem. It is a scale, data, and iteration problem— and Tesla is already far, far down that road while others are just getting started,” Beisel wrote.
Musk responded to Beisel’s post, stating that “Roughly 10 billion miles of training data is needed to achieve safe unsupervised self-driving. Reality has a super long tail of complexity.” This is quite interesting considering that in his Master Plan Part Deux, Elon Musk estimated that worldwide regulatory approval for autonomous driving would require around 6 billion miles.
FSD’s total training miles
As 2025 came to a close, Tesla community members observed that FSD was already nearing 7 billion miles driven, with over 2.5 billion miles being from inner city roads. The 7-billion-mile mark was passed just a few days later. This suggests that Tesla is likely the company today with the most training data for its autonomous driving program.
The difficulties of achieving autonomy were referenced by Elon Musk recently, when he commented on Nvidia’s Alpamayo program. As per Musk, “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.” These sentiments were echoed by Tesla VP for AI software Ashok Elluswamy, who also noted on X that “the long tail is sooo long, that most people can’t grasp it.”

Tesla earns top honors at MotorTrend’s SDV Innovator Awards
MotorTrend’s SDV Awards were presented during CES 2026 in Las Vegas.
Tesla emerged as one of the most recognized automakers at MotorTrend’s 2026 Software-Defined Vehicle (SDV) Innovator Awards.
As could be seen in a press release from the publication, two key Tesla employees were honored for their work on AI, autonomy, and vehicle software. MotorTrend’s SDV Awards were presented during CES 2026 in Las Vegas.
Tesla leaders and engineers recognized
The fourth annual SDV Innovator Awards celebrate pioneers and experts who are pushing the automotive industry deeper into software-driven development. Among the most notable honorees for this year was Ashok Elluswamy, Tesla’s Vice President of AI Software, who received a Pioneer Award for his role in advancing artificial intelligence and autonomy across the company’s vehicle lineup.
Tesla also secured recognition in the Expert category, with Lawson Fulton, a staff Autopilot machine learning engineer, honored for his contributions to Tesla’s driver-assistance and autonomous systems.
Tesla’s software-first strategy
While automakers like General Motors, Ford, and Rivian also received recognition, Tesla’s multiple awards stood out given the company’s outsized role in popularizing software-defined vehicles over the past decade. From frequent OTA updates to its data-driven approach to autonomy, Tesla has consistently treated vehicles as evolving software platforms rather than static products.
This has made Tesla’s vehicles very unique in their respective sectors, as they are arguably the only cars that objectively get better over time. This is especially true for vehicles that are loaded with the company’s Full Self-Driving system, which are getting progressively more intelligent and autonomous over time. The majority of Tesla’s updates to its vehicles are free as well, which is very much appreciated by customers worldwide.

Judge clears path for Elon Musk’s OpenAI lawsuit to go before a jury
The decision maintains Musk’s claims that OpenAI’s shift toward a for-profit structure violated early assurances made to him as a co-founder.
A U.S. judge has ruled that Elon Musk’s lawsuit accusing OpenAI of abandoning its founding nonprofit mission can proceed to a jury trial.
The decision maintains Musk’s claims that OpenAI’s shift toward a for-profit structure violated early assurances made to him as a co-founder. These claims are directly opposed by OpenAI.
Judge says disputed facts warrant a trial
At a hearing in Oakland, U.S. District Judge Yvonne Gonzalez Rogers stated that there was “plenty of evidence” suggesting that OpenAI leaders had promised that the organization’s original nonprofit structure would be maintained. She ruled that those disputed facts should be evaluated by a jury at a trial in March rather than decided by the court at this stage, as noted in a Reuters report.
Musk helped co-found OpenAI in 2015 but left the organization in 2018. In his lawsuit, he argued that he contributed roughly $38 million, or about 60% of OpenAI’s early funding, based on assurances that the company would remain a nonprofit dedicated to the public benefit. He is seeking unspecified monetary damages tied to what he describes as “ill-gotten gains.”
OpenAI, however, has repeatedly rejected Musk’s allegations. The company has stated that Musk’s claims were baseless and part of a pattern of harassment.
Rivalries and Microsoft ties
The case unfolds against the backdrop of intensifying competition in generative artificial intelligence. Musk now runs xAI, whose Grok chatbot competes directly with OpenAI’s flagship ChatGPT. OpenAI has argued that Musk is a frustrated commercial rival who is simply attempting to slow down a market leader.
The lawsuit also names Microsoft as a defendant, citing its multibillion-dollar partnerships with OpenAI. Microsoft has urged the court to dismiss the claims against it, arguing there is no evidence it aided or abetted any alleged misconduct. Lawyers for OpenAI have also pushed for the case to be thrown out, claiming that Musk failed to show sufficient factual basis for claims such as fraud and breach of contract.
Judge Gonzalez Rogers, however, declined to end the case at this stage, noting that a jury would also need to consider whether Musk filed the lawsuit within the applicable statute of limitations. Still, the dispute between Elon Musk and OpenAI is now headed for a high-profile jury trial in the coming months.
