SpaceX will attempt Falcon 9 upper stage landings in 2018, says Shotwell
SpaceX also hopes to create an Internet constellation around Mars
In a candid and light-hearted presentation given at the Massachusetts Institute of Technology, SpaceX President Gwynne Shotwell revealed a considerable amount of exciting information about the space launch company’s future prospects and near-term goals.
Fascinatingly, Shotwell confirmed that SpaceX is currently attempting to procure nuclear materials in order to conduct research and development of nuclear propulsion for spacecraft. Nuclear-powered methods of propulsion have the potential to drastically increase the efficiency of spacecraft once in orbit, with the primary benefit being faster travel times around the Solar System. Faster transit times for manned spacecraft would translate into fewer consumables needed for those journeys, increasing the amount of other supplies that could be brought in a single trip. Beyond the orbit of Mars, other destinations humans might like to visit will require non-chemical propulsion, with more traditional rocketry leading to one-way voyages measured in years.

Equally exciting, she stated that SpaceX plans to attempt the first soft landing of Falcon 9’s upper stage before the end of 2018. Second stage recovery efforts would proceed much like Falcon 9’s first stage recovery did, beginning with attempts to land softly in the ocean and later bring in a droneship to attempt legitimate recoveries of the vehicle. While SpaceX’s now highly successful program of first stage recovery has taken the first steps to appreciably lower the cost of access to orbit, as much as 30% or more of the cost of every Falcon 9 launch can be found in the second stage and its many components, all of which are currently discarded every launch. Second stage recovery and reuse is nevertheless absolutely crucial to SpaceX’s and Elon Musk’s goal of reducing launch costs by anywhere from a factor of 10 to 100.
Still, the payload fairing – a major component of the Falcon 9 – costs approximately $5 million on its own, nearly 10% of the cost of a $62 million expendable launch. SpaceX has been making concerted progress towards fairing recovery and reuse, and Musk has said that he expects SpaceX to accomplish the first successful fairing recoveries before the end of 2017. The second stage is thus the obvious next step if the goal is to create a fully-reusable Falcon 9. SpaceX, however, seem to be prioritizing a different path.

Shotwell clarified that SpaceX would not attempt to reuse Falcon 9’s upper stage, even if recovery efforts succeed. This suggests that SpaceX is planning to focus the majority of its research and development staff and capital on their considerably larger “BFR (Big Falcon Rocket) planetary colonizer” vehicle, which will be unveiled for the first time later today. Hence, Shotwell’s comment lends confidence to the belief that Falcon 9 will never become fully reusable, which makes sense. The decision to focus energy on a new launch vehicle is arguably a more efficient and productive task than modifying Falcon 9 even more drastically. The development of an entirely new rocket offers SpaceX the freedom to design for complete reusability from the start, whereas Falcon 9’s path to partial reusability has been inevitably circuitous.
Finally, Shotwell briefly discussed SpaceX’s desire to create a vast constellation of Internet satellites around Earth, stating that their goal was “make scads of cash, spend it going to Mars, [and] give Mars broadband too!”. This aligns with speculation and leaked financial documents. Just yesterday, the Federal Communications Commission (FCC) held an Open Commission meeting where they voted to hand off certain aspects of regulatory approval to the International Telecommunications Union, which is a relatively positive development for SpaceX’s satellite constellation.

Regardless, Musk is bound to reveal some even more thrilling details about SpaceX in his presentation at the 2017 International Astronautical Congress. Currently scheduled for 4 a.m UTC on September 29, or 9:30 p.m. PDT on September 28, and an official SpaceX.com livestream is expected to be provided for those who were unable to make the long journey to Adelaide, Australia.

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.
