SpaceX director says six Crew Dragon launches per year is a sustainable goal
A senior manager says that SpaceX could sustainably launch six or more Crew Dragons per year if the market for private missions grows large enough to demand it.
Benji Reed, Senior Director of Human Spaceflight Programs, offered his thoughts on the matter in a press conference following SpaceX’s successfully recovery of Crew Dragon and four private Axiom-1 astronauts from the Gulf of Mexico, marking the end of the first all-private mission to the International Space Station (ISS). Asked what kind of launch cadence SpaceX believes it could handle going forward, Reed stated that he “would love to see…half a dozen crew flights…or more” per year and believes that “SpaceX can sustain that [pace] if there’s a market for it.”
The question is an important one after a SpaceX executive confirmed to Reuters earlier this year that the company has already ended production of Crew Dragon after building just a handful of reusable capsules. With that fleet of four spacecraft, it hasn’t been clear how many crewed missions SpaceX can – or thinks it can – launch each year. To some extent, it’s long been expected that SpaceX would try to replace both Falcon rockets and Dragon spacecraft with Starship as soon as the next-generation fully-reusable rocket is ready.
However, without major redesigns or a new and heavily modified variant of the rocket’s upper stage, it’s difficult to imagine NASA transitioning its International Space Station astronaut launches from Dragon to Starship anytime soon. Even though Starship could feasibly revolutionize spaceflight and NASA has already contracted with SpaceX to build a version of the rocket to land NASA astronauts on the Moon, the one thing it’s hard to imagine the space agency ever compromising on is safety. Crew Dragon has a built-in launch escape system that allows the capsule to almost instantly whisk astronauts away from a failing rocket at any point before or during a launch.
Starship has no such escape system and SpaceX has no apparent plans to develop a variant of the crew-carrying ship with a comparable abort system. Because the Starship rocket’s second stage is the orbital spacecraft, crew cabin, and reentry vehicle, it simply isn’t possible for the current design of the next-generation vehicle to match the theoretical safety of Falcon 9 and Crew Dragon. CEO Elon Musk has discussed increasing the number of engines on Starship to allow it to escape from a failing booster but that would leave astronauts with no way to escape from the upper stage itself.
On top of Dragon’s fundamentally superior safety capabilities, Falcon 9 also has an extraordinary record of 125 consecutively successful launches. If NASA wouldn’t let Dragon launch its astronauts on Falcon 9 without an active escape system, it’s hard to imagine how many consecutive launch successes Starship would need before the agency would even think about retiring Crew Dragon.
This is all to say that SpaceX is likely going to be stuck operating Crew Dragon for the indefinite future as long as it’s too stubborn to develop a true launch escape system for Starship. Even though the recently announced Polaris Program aims to culminate in the “first flight of Starship with humans on board,” it’s likely that most private SpaceX crew launch customers will follow NASA’s lead.
Thankfully, even with four Crew Dragon capsules, it’s likely that SpaceX can manage significantly more than six crewed missions per year if the demand is there and commercial passengers – mirroring NASA – aren’t ready to risk flying on Starship. Already, SpaceX has successfully launched the same Crew Dragon capsule to orbit twice in 137 days. If SpaceX continues flying back-to-back NASA crew transport missions while Boeing’s Starliner inches through qualification, that will tie up two Dragons per year, limiting SpaceX to two launches for NASA and around four to five private astronaut launches per year.
Assuming Starliner finally reaches operational readiness and begins supporting every other NASA crew launch, SpaceX could feasibly launch one NASA mission and seven private missions (lasting up to two weeks each) per year by the end of 2023. Additionally, if SpaceX can improve Crew Dragon turnaround to 120 days, the fleet could support 10 crew launches per year. 90 days? 13 launches per year. Private missions to the ISS would add plenty of schedule constraints, reducing the total number of opportunities, but that’s a minor problem in comparison.
The only lingering technical concern, then, is the longevity of SpaceX’s Crew Dragon capsule fleet. SpaceX and NASA have initially certified each capsule for five missions, but after Crew-4’s April 27th launch, the fleet has already eaten up 7 of the 20 flights that limit permits. Assuming no additional demand for private launches, the remaining 13 ‘certified’ flights might last SpaceX through 2024. Sooner than later, with NASA’s blessing, it will either need to significantly increase the number of missions each capsule is certified to fly, build new capsules, or find a way to transition to Starship.

Tesla Cybercab display highlights interior wizardry in the small two-seater
Photos and videos of the production Cybercab were shared in posts on social media platform X.
The Tesla Cybercab is currently on display at the U.S. Department of Transportation in Washington, D.C., and observations of the production vehicle are highlighting some of its notable design details.
Photos and videos of the production Cybercab were shared in posts on social media platform X.
Observers of the Cybercab display unit noted that the two-seat Robotaxi provides unusually generous legroom for a vehicle of its size. Based on the vehicle’s video, the compact two-seater appears to offer more legroom than Tesla’s larger vehicles such as the Model Y, Model X, and Cybertruck.
The Cybercab’s layout allows Tesla to dedicate nearly the entire cabin to passengers. The vehicle is designed without a steering wheel or pedals, which helps maximize interior space.
Footage from the display also highlights the Cybercab’s large center screen, which is positioned prominently in front of the passenger bench. The display appears intended to provide entertainment and ride information while the vehicle operates autonomously.
Images of the vehicle also show an additional camera integrated into the Cybercab’s C-pillar. The extra camera appears to expand the vehicle’s field of view, which would be useful as Tesla works toward fully unsupervised Full Self-Driving.
Tesla engineers have previously explained that the Cybercab was designed to be highly efficient both in manufacturing and in operation. Cybercab Lead Engineer Eric E. stated in 2024 that the Robotaxi would be built with roughly half the number of parts used in a Model 3 sedan.
“Two seats unlocks a lot of opportunity aerodynamically. It also means we cut the part count of Cybercab down by a substantial margin. We’re gonna be delivering a car that has roughly half the parts of Model 3 today,” the Tesla engineer said.
The Tesla engineer also noted that the Cybercab’s cargo area can accommodate multiple golf bags, two carry-on suitcases, and two full-size checked bags. The trunk can also fit certain bicycles and a foldable wheelchair depending on size, which is quite impressive for a small car like the Cybercab.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.
