SpaceX, Firefly Aerospace targeting three rocket launches in two days
Update: As is a common occurrence in spaceflight, two of the three planned missions have been delayed or scrubbed. Firefly’s second Alpha launch has slipped to no earlier than (NET) September 12th after an aborted attempt on the 11th, and SpaceX’s Starlink 4-34 mission was pushed from September 11th to September 13th.
SpaceX and Firefly Aerospace are on track to attempt three orbital launches this weekend as the former continues to relentlessly assemble a constellation of Starlink internet satellites and the latter works to secure its first success.
On the heels of 40 successful Falcon 9 launches this year, SpaceX is a few days away from two more Starlink missions that will likely leave the company with more than 3000 working satellites in orbit.
Founded in 2017, 15 years after SpaceX, Firefly Aerospace is almost entirely focused on one near-term goal: the first successful launch of its Alpha rocket.
Firefly’s Alpha rocket lifted off for the first time on September 2nd, 2021. Just moments after launch, a faulty cable caused one of the Alpha first stage’s four Reaver engines to shut down, immediately dooming the attempt. The rocket inexplicably persevered, though, and managed more than two minutes of powered flight before it lost control, became a range safety risk, and was terminated.
More than a year later, Firefly believes it has solved the problems that doomed Alpha Flight 1 and is on the cusp of the rocket’s second launch attempt, which has been scheduled no earlier than (NET) 3pm PST (22:00 UTC) on Sunday, September 11th.
Recently, the second fully stacked Alpha rocket completed a wet dress rehearsal and static fire while installed on Firefly’s Vandenberg Space Force Base (VSFB) SLC-2W pad, confirming its readiness for flight. Measuring 1.8 meters (6 ft) wide and 29.5 meters (~95 ft) tall, Alpha is about half the width and height of SpaceX’s Falcon 9 workhorse, and Firefly estimates that the expendable rocket will be able to launch up to 1.17 tons (~2560 lb) to Low Earth Orbit (LEO).
That’s several times more performance per launch than competitors like Rocket Lab, Astra Space, and Virgin Orbit, but 14 times less than a partially reusable Falcon 9. At $15 million apiece, however, the rocket’s list price will be 4.5 times less than Falcon 9’s, which could be enough to create a niche for customers that want to spend a bit more to send smaller satellites exactly where they want instead of getting dropped off in the general vicinity as a rideshare payload.
Demonstrating an impressive level of transparency, Firefly will offer a public livestream of Alpha’s second flight in full awareness that it could ultimately broadcast a launch failure for the second time in a row. There are very few instances in the history of spaceflight where a new group’s new rocket successfully reached orbit on its first launch, so it’s a credit to the startup to acknowledge the reality that launch failures are a common extension of the development process, rather than something to hide from the public.
SpaceX knows that reality well. Falcon 1, its first rocket, was about half the size of Firefly’s Alpha and suffered three launch failures in two and half years before finally succeeding on its fourth attempt. More than a magnitude larger, Falcon 9 likely benefitted from SpaceX’s Falcon 1 experience and had a much smoother start to life, though it did eventually experience its own share of failures years after its 2010 debut.
12 years later, Falcon 9 is one of the most successful launch vehicles of all time, and has simultaneously pioneered the commercially viable reuse of orbital-class rockets. Currently on a historic pace of one launch every ~6.2 days in 2022, Falcon 9 recently completed its 146th successful launch in a row and 173rd successful launch overall.
Hopefully continuing those trends, Next Spaceflight reports that Falcon 9 is scheduled to launch two more batches of Starlink satellites at 9:10 pm EDT on Saturday, September 10th, and 10:53 pm EDT on Sunday, September 11th. In addition to several dozen Starlink satellites, the first mission – Starlink 4-2 – is expected to carry a relatively large 1.5-ton (~3300 lb) satellite prototype for space-to-phone communications startup AST SpaceMobile. The second mission, known as Starlink 4-34, should be a dedicated launch of another 53 or 54 Starlink satellites.

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.
