SpaceX’s second astronaut launch a step closer after NASA announcement
SpaceX’s second astronaut launch is a a step closer to flight after NASA and JAXA announced the third and fourth astronauts assigned to ride Crew Dragon to the International Space Station (ISS) on its first operational mission.
On the cusp of March 30th and 31st, the Japanese Space Agency (JAXA) made the first Crew Dragon-related announcement of the day, revealing the assignment of astronaut Soichi Noguchi to SpaceX’s Crew-1 launch. Hinging entirely on the success of SpaceX’s imminent Demo-2 astronaut launch debut, a critical demonstration mission scheduled to launch no earlier than mid-to-late May 2020, Crew Dragon’s Crew-1 mission will be the spacecraft’s first operational mission ferrying humans to and from the space station. NASA followed up JAXA’s announced hours later, revealing that astronaut Shannon Walker would be the fourth and final crew member aboard Crew Dragon’s Crew-1 launch.
Including Boeing’s Starliner and SpaceX’s Crew Dragon crewed demonstration missions, known as the Crewed Flight Test and Demonstration Mission 2 (Demo-2 or DM-2), respectively, NASA has purchased six astronaut launches from both providers. In theory, one Starliner and Crew Dragon launch per year – spaced out six or so months apart – should be enough to meet NASA’s space station transportation needs, meaning that the space agency’s 12 contracts should last until 2025 or 2026. Boeing’s Starliner appears to be delayed indefinitely after multiple near-catastrophic failures on its first Orbital Flight Test (OFT) but if SpaceX’s Demo-2 mission goes as planned, Crew Dragon could be set to enter operational duty as early as Q4 2020.
SpaceX’s Crew-1 mission manifest now includes NASA astronauts Mike Hopkins, Victor Glover, and Shannon Walker, as well as JAXA astronaut Soichi Noguchi and will likely carry an additional 100-200 kg (200-400 lb) of cargo to the International Space Station (ISS). While all eyes are reasonably on Crew Dragon’s Demo-2 mission, right now, the spacecraft’s Crew-1 through -5 missions are where SpaceX has the opportunity to gain extensive experience launching humans on an operational, semi-routine basis.
Making up at least half of the backbone of NASA’s new domestic astronaut launch capabilities, Crew Dragon and Falcon 9 will hopefully prove themselves to be as reliable and dependable as they and their predecessors have been over the years. Cargo Dragon, SpaceX’s first orbital-class spacecraft and the first private vehicle to visit the ISS, has successfully resupplied the space station and safely returned to Earth each of the 20 times the spacecraft reached orbit. Unsurprisingly, SpaceX ran into intermittent technical issues over those numerous flights, but all of those anomalies were solved on the fly and never prevented mission success or spacecraft recovery.
Falcon 9’s first in-flight failure destroyed the CRS-7 Cargo Dragon spacecraft in June 2015 and cut the mission short before it could reach orbit, but the failure was entirely unrelated to Dragon. Falcon 9’s second catastrophic failure occurred less than 15 months later, also a fault of a small but explosive rocket design flaw. From January 2017 to March 2020, however, Falcon 9 and Falcon Heavy rockets have completed 58 consecutively successful launches. With that streak of success, by certain measures, Falcon has become the most reliable operational rocket family in the world, tied with ULA’s famously reliable Atlas V and slightly better than Arianespace’s Ariane 5.
In short, while Cargo Dragon can’t hold a candle to the sheer scale of Russia’s Soyuz and Progress spacecraft flight histories, Falcon 9 is one of the two most reliable launch vehicles in operation and Crew Dragon will stand on the back of one of the most reliable spacecraft ever built in recent history. With (perhaps more than a little) luck, Boeing’s Starliner spacecraft – launched atop Atlas V, the other most reliable operational rocket – will hopefully be able to develop its own record of reliability in the next several years, but it will never be able to compete with the Cargo Dragon heritage Crew Dragon directly benefits from.
Boeing’s next Starliner mission is up in the air after the spacecraft’s almost disastrous orbital launch debut. Most likely, NASA will require a second uncrewed flight test, this time including the space station rendezvous, docking, and departure attempt Boeing had to cancel after Starliner’s major software failure. A second OFT would likely be ready for flight no earlier than Q3 or Q4 2020, depending on NASA’s investigation findings and requirements. If NASA remains confident and things go perfectly during the likely OFT2 mission, Starliner’s Crew Flight Test (CFT) could maybe launch by the end of 2020.
Crew Dragon’s Demo-2 astronaut launch debut is aiming for what NASA says is a mid-to-late May launch, although the mission is more likely to fly in the late-May to mid-June time frame. If Demo-2 launches on schedule (H1 2020) and is as flawless as Crew Dragon’s uncrewed Demo-1 launch debut, SpaceX could be ready to launch its second astronaut mission (Crew-1) as early as Q4 2020, possibly around the start of the quarter. With so much contingent on near-term reviews and tests, schedules beyond Demo-2 are unsurprisingly fluid.

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.
