Boeing Starliner and SpaceX Crew Dragon crew capsules on track for back-to-back launches
NASA Commercial Crew partners Boeing and SpaceX are taking big steps towards two unique flight tests of their respective Starliner and Crew Dragon spacecraft, and – if the stars align – could jam-pack next month with spaceflight milestones.
In the last two weeks alone, both companies have checked off major milestones while preparing their human-rated spacecraft for flight, and – with a little luck over the next few weeks – Starliner and Crew Dragon processing could align for back-to-back launches in the last few weeks of 2019.
On Atlas’ shoulders
Starliner’s uncrewed orbital flight test (OFT) is currently scheduled no earlier than (NET) December 17th and Boeing – after years of delays – is finally on the last legs of preparation for the spacecraft’s orbital launch debut (OFT). On November 4th, some 12 months after it was originally planned to occur, Boeing’s Starliner spacecraft completed a (mostly) successful pad abort test, demonstrating the ability to whisk astronauts away from a failing rocket or any other pad emergency prior to launch. Aside from a parachute deployment failure caused by insufficient quality assurance checkouts, Starliner performed exactly as expected.
With the Starliner pad abort now complete, the spacecraft’s OFT is front and center. On November 20th, United Launch Alliance (ULA) CEO Tory Bruno announced that the company – chosen by Boeing to launch Starliner – had successfully completed a “Mission Dress Rehearsal”, more or less a virtual simulation of Atlas V launch operations.
According to ULA, the MDR was a joint test conducted by ULA teams in Denver and Cape Canaveral, personnel from NASA and Boeing, and the Cape Canaveral Air Force Station (CCAFS) 45th Space Wing.
On November 21st, the day after Atlas V’s successful MDR, Boeing officially handed off the OFT Starliner to ULA, who used a small wheeled crawler to transport the spacecraft from Boeing’s Commercial Crew and Cargo Processing Facility (C3PF) to ULA’s LC-41 launch complex. Finally, shortly after the transporter arrived at LC-41, ULA craned the spacecraft to the top of its Vertical Integration Facility (VIF) and technicians secured Starliner to the rocket’s payload adapter and Centaur upper stage, itself recently stacked atop an Atlas V booster.
The time left ahead of OFT will be used to ensure a successful first flight of both the spacecraft and its uniquely-configured launch vehicle. OFT will be the first time Atlas V launches a payload without a fairing. Combined with the unusual fact that Starliner is significantly wider than the rocket’s Centaur upper stage, a large skirt and other unusual aerodynamic features had to be added to counterbalance dangerous instability that could otherwise crop up in flight.
Of note, the OFT Starliner’s service section (the cylindrical lower half) will not launch with an operational abort system, meaning that the system of four powerful engines are either entirely absent or will be disabled in flight.
Boeing’s Starliner OFT will more or less mirror Crew Dragon’s March 2019 launch debut, nominally launching, reaching orbit, rendezvousing and docking with the ISS, and successfully returning to Earth a week or so later. Although NASA did not originally require its CCP providers to perform uncrewed orbital flight tests prior to their first attempted crewed launches, NASA officials have since made it clear that they are extremely grateful that Boeing and SpaceX proposed them.
Encore!
At the same time as Boeing and ULA are preparing for Starliner’s first orbital launch, SpaceX is in the late stages of preparing Falcon 9 and Crew Dragon for the spacecraft’s In-Flight Abort (IFA), a test that Boeing chose not to perform – NASA required a pad abort but left the rest up to its providers to propose (or not propose). On November 13th, Crew Dragon capsule C205 successfully fired up two Draco maneuvering thrusters and its eight integrated SuperDraco abort engines, verifying that a major design flaw that destroyed capsule C201 has likely been alleviated.
Crew Dragon’s IFA test is scheduled no earlier than December 2019 and will likely fall somewhere in the second half of the month, potentially putting it just days before or after Starliner’s orbital launch debut. All told, the last month of 2019 is likely to be jam-packed with major spaceflight milestones, particularly for NASA’s Commercial Crew Program. If all goes as planned during Boeing and SpaceX’s imminent flight tests, both providers believe they could be ready for their first astronaut launches in early 2020.

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.
