SpaceX wins launch contracts for three more Launcher space tugs
Startup ‘Launcher Space’ has chosen SpaceX to launch at least three more ‘Orbiter’ space tugs, meaning that the company will have a payload on every dedicated SpaceX rideshare launch planned from Q4 2022 to the end of 2023.
Following SpaceX’s third successful dedicated rideshare launch in January 2022, the company has another two missions – Transporter-4 and -5 – scheduled in the first half of the year. In October 2021, Launcher announced its Orbiter spacecraft program and plans to manifest the first vehicle on a SpaceX rideshare mission – likely Transporter-6 – scheduled to launch no earlier than (NET) October 2022.
Announced in the summer of 2019, SpaceX’s Smallsat Rideshare Program has offered one of the easiest and most affordable tickets to space for two and a half years. Following a handful of Starlink rideshare missions in 2020, SpaceX kicked off dedicated Transporter launches in January 2021 and has since delivered more than 320 customer satellites and payloads to orbit. By treating each Transporter mission a bit like public transit and also opening the door for third-party launch servicers, SpaceX has been able to somewhat simplify the tedious process of organizing large-scale rideshare missions.
Most importantly, thanks to the unprecedented affordability of its Falcon 9 rocket, SpaceX has allowed rideshare customers to reap a great deal of the benefits by charging just $1M per 200-kilogram (440 lb) ‘slot’ and a flat $5,000 for each additional kilogram. To anyone unfamiliar with the cost of spaceflight, that might seem obscene, but it’s extraordinarily affordable and far cheaper than every advertised alternative. Astra Space, the cheapest dedicated smallsat launch provider, sells a Rocket 3 vehicle capable of launching about 50 kilograms (110 lb) to a similar orbit for ~$3.5M – equivalent to $70,000 per kilogram. Rocket 3 has only completed one successful launch, however. Rocket Lab’s more accessible Electron rocket costs at least $7.5M for ~200 kilograms to sun-synchronous orbit (SSO) – a price of $37,500/kg.
Nonetheless, the single most significant drawback of rideshares – a one-size-fits-all orbit – remains. Short of a much more complex, expensive trajectory that would require Falcon 9’s upper stage to reignite several times, every payload launched on Transporter missions ends up in the same initial orbit. To solve that problem, a not insignificant number of companies have been formed in recent years to develop competitive orbital transfer vehicles. In theory, propulsive space tugs could potentially give rideshare payloads the best of both worlds – ultra-cheap launch costs and, within reason, delivery to a specific orbit of choice.
Launcher’s Orbiter is perhaps the most promising of the lot. Scheduled to debut no earlier than (NET) October 2022, Orbiter will use pressure-fed 3D-printed thrusters fed by ethane and nitrous oxide propellant stored in 3D-printed tanks. The company has already begun printing and hot-fire testing multiple thrusters, has received the first set of Orbiter avionics and solar panels, and seemingly remains very confident about the schedule for that spacecraft’s launch debut.
Additionally, Launcher is actually publicizing pricing for the stage. Bought outright, each Orbiter will cost about $400,000. Using its full 400 kg (880 lb) payload margin, a Falcon 9 launch with Orbiter – enabling precise orbital targeting – would cost a prospective customer about $3.5M – less than $9,000/kg. For a 200 kg (440 lb) payload, a Falcon 9 + Orbiter launch might cost less than $7,000/kg (~$2.5M). For Orbiter rideshare missions, Launcher will charge between $8,000 and $25,000 per kilogram – multiple times cheaper than alternatives at the low end and still competitive at the high end.
Other companies like Spaceflight Industries, D-Orbit, Momentus, Exolaunch, and more are also developing – or already flight-testing – their own space tugs, though most are being cryptic about their prices and capabilities.

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.
