On August 22nd, spaceflight startup Momentus Space and launch heavyweight SpaceX announced the first public launch contract to fall under the umbrella of the latter company’s recently-announced Satellite Rideshare Program.

Meant to provide a reliable, consistent, and affordable form of shuttle-like access to orbit, SpaceX’s rideshare program will – pending demand – involve no less than one dedicated Falcon 9 launch per year, capable of placing 15+ metric tons (33,000+ lbs) into low Earth orbit. Although SpaceX’s rideshare proposal is far from revolutionary, the company’s contract with Momentus Space appears to be more than a basic launch service agreement, potentially opening doors for far more flexible rideshare launches in the future.

Since its November 2017 founding, Momentus Space has been able to put money where its mouth is far more so than any comparable space tug hopeful, of which there are several. The concept that has helped Momentus raise nearly $34M in just 1.5 years is relatively simple: build a spacecraft whose sole purpose is to propel other spacecraft to their final orbit(s).

Known as a space tug, the concept is about as old as practical spaceflight itself, and interest in actually developing the concept from paper to hardware has grown exponentially in the last 5-10 years, thanks in large part to an unprecedented boom in commercial spaceflight activity. Applied more specifically, modern efforts like Momentus tend to have ambitious goals couched behind much more achievable (and marketable) concepts.

Momentus Space’s first goal is to bridge the gap between the low cost of smallsat rideshare missions on large rockets and the convenience of smallsat launches on much smaller rockets by building lightweight, simple, and cheap orbital tugs. The first tug the company wants to field is called Vigoride and will measure approximately 2ft x 2ft (0.4m²) and weigh just 80 kg (175 lb) fully fueled. If launched to a 600 km (370 mi) sun-synchronous orbit (SSO), Vigoride will be able to deliver as much as 220 kg (~500 lb) to a final circular orbit of ~1500 km (930 mi) or place 250 kg (550 lb) of satellites into 10+ separate orbits.

Water plasma rockets (!?)

By far the most innovative and potentially revolutionary aspect of Momentus’ plans is its custom propulsion system of choice: water plasma rockets. In simple terms, Momentus space tugs would quite literally turn water and sunlight into a method of in-space propulsion that can offer both moderate efficiency and relatively high thrust. Using solar arrays, the space tug would charge batteries that would then power an extremely high-power microwave electrothermal thruster (MET).

In the case of Momentus, the exotic form of propulsion uses microwaves to almost instantaneously turn liquid water into plasma, an ionized, electrically-charged gas that can then be directed with a magnetic nozzle to produce thrust. Aside from the decent performance it offers, water-based MET allows a given satellite to completely avoid heavy pressure vessels, doesn’t require extremely high voltages, and uses a fully non-toxic propellant (water).

Momentus plans to rely heavily on custom-designed and built water plasma thrusters for its space tugs.

The fact that pure water is so incredibly benign, non-toxic, and accessible opens up a realm of possibilities. Momentus already has plans to launch Vigorides from the International Space Station, and that could eventually expand into actual in-space reuse in which water-powered satellites might dock with the ISS to load more water and pick up new payloads.

In the case of SpaceX, it appears that the company has inked a more two-way agreement with Momentus, in the sense that prospective customers of SpaceX’s Satellite Rideshare Program might actually be able to arrange for their satellites to be included on Vigoride. Vigoride would then be able to deliver each payload – up to 250 kg worth – to its own orbit, potentially far more convenient than simply being kicked off at a lone orbital bus stop. As Momentus matures its technology and moves from Vigoride to Vigoride Extended and beyond, a partnership with SpaceX’s Satellite Rideshare Program could grow into an almost unbeatable turnkey option for the smallsat industry.

Momentus Space is already sketching out plans for future (and much larger) spacecraft.

Momentus took its first major step towards building capable and marketable space tugs in July 2019 when the company launched X1, its first orbit-worthy satellite prototype. Although the company has been dead silent as to the actual status of that prototype, even a failure would still serve as an invaluable learning opportunity, even if it would be an inconvenient setback. Vigoride’s first test flight was planned as early as late 2019, although the status of that schedule is uncertain.

Tesla is adding an awesome new driving feature to Model Y vehicles, effective on Juniper-updated models considered model year 2026 or newer.

Tesla is rolling out a new “Comfort Braking” feature with Software Update 2026.8. The feature is exclusive to the new Model Y, and is currently unavailable for any other vehicle in the Tesla lineup.

Tesla writes in the release notes for the feature:

“Your Tesla now provides a smoother feel as you come to a complete stop during routine braking.”

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.

There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.

This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.

Tesla set to activate long-awaited Cybertruck feature

Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.

Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.

We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.

Tesla finally brings a Robotaxi update that Android users will love

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android.

Tesla is finally bringing an update of its Robotaxi platform that Android users will love — mostly because it seems like they will finally be able to use the ride-hailing platform that the company has had active since last June.

Based on a decompile of software version 26.2.0 of the Robotaxi app, Tesla looks to be ready to roll out access to Android users.

According to the breakdown, performed by Tesla App Updates, the company is preparing to roll out an Android version of the app as it is developing several features for that operating system.

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android:

“Strings like notification_channel_robotaxid_trip_name and android_native_alicorn_eta_text show exactly how Tesla plans to replicate the iOS Live Activities experience. Instead of standard push alerts, Android users are getting a persistent, dynamically updating notification channel.”

This is a big step forward for several reasons. From a face-value perspective, Tesla is finally ready to offer Robotaxi to Android users.

The company has routinely prioritized Apple releases because there is a higher concentration of iPhone users in its ownership base. Additionally, the development process for Apple is simply less laborious.

Tesla is working to increase Android capabilities in its vehicles

Secondly, the Robotaxi rollout has been a typical example of “slowly then all at once.”

Tesla initially released Robotaxi access to a handful of media members and influencers. Eventually, it was expanded to more users, so that anyone using an iOS device could download the app and hail a semi-autonomous ride in Austin or the Bay Area.

Opening up the user base to Android users may show that Tesla is preparing to allow even more users to utilize its Robotaxi platform, and although it seems to be a few months away from only offering fully autonomous rides to anyone with app access, the expansion of the user base to an entirely different user base definitely seems like its a step in the right direction.

Lucid unveils Lunar Robotaxi in bid to challenge Tesla’s Cybercab in the autonomous ride hailing race

Lucid Group pulled back the curtain on its purpose-built autonomous robotaxi platform dubbed the Lunar Concept. Announced at its New York investor day event, Lunar is arguably the company’s most ambitious concept yet, and a direct line of sight toward the autonomous ride haling market that Tesla looks to control.

At Lucid Investor Day 2026, the company introduced Lunar, a purpose-built robotaxi concept based on the Midsize platform.

A comparison to Tesla’s Cybercab is unavoidable. The concept of a Tesla robotaxi was first introduced by Elon Musk back in April 2019 during an event dubbed “Autonomy Day,” where he envisioned a network of self-driving Tesla vehicles transporting passengers while not in use by their owners. That vision took another major step in October 2024 when, Musk unveiled the Cybercab at the Tesla “We, Robot” event held at Warner Bros. Studios in Burbank, California, where 20 concept Cybercabs autonomously drove around the studio lot giving rides to attendees.

Fast forward to today, and Tesla’s ambitions are finally materializing, but not without friction. As we recently reported, the Cybercab is being spotted with increasing frequency on public roads and across the grounds of Gigafactory Texas, suggesting that the company’s road testing and validation program is ramping meaningfully ahead of mass production. Tesla already operates a small scale robotaxi service in Austin using supervised Model Ys, but the Cybercab is designed from the ground up for high-volume, low-cost production, with Musk stating an eventual goal of producing one vehicle every 10 seconds.

At Lucid Investor Day 2026, the company introduced Lunar, a purpose-built robotaxi concept based on the Midsize platform.

Into this landscape steps Lucid’s Lunar. Built on the company’s all-new Midsize EV platform, which will also underpin consumer SUVs starting below $50,000. The Lunar mirrors the Cybercab’s core philosophy of having two seats, no driver controls, and a focus on fleet economics. The platform introduces Lucid’s redesigned Atlas electric drive unit, engineered to be smaller, lighter, and cheaper to manufacture at scale.

Unlike Tesla’s strategy of building its own ride hailing network from scratch, Lucid is partnering with Uber. The companies are said to be in advanced discussions to deploy Midsize platform vehicles at large scale, with Uber CEO Dara Khosrowshahi publicly backing Lucid’s engineering credentials and autonomous-ready architecture.

In the investor day event, Lucid also outlined a recurring software revenue model, with an in-vehicle AI assistant and monthly autonomous driving subscriptions priced between $69 and $199. This can be seen as a nod to the software revenue stream that Tesla has long championed with its Full Self-Driving subscription.

Tesla’s Cybercab is targeting a price point below $30k and with operating costs as low as 20 cents per mile. But with regulatory hurdles still ahead, the window for competition is open. Lucid’s Lunar may not have a launch date yet, but it arrives at a pivotal moment, and when the robotaxi race is no longer viewed as hypothetical. Rather, every serious EV player needs to come to bat on the same plate that Tesla has had countless practice swings on over the last seven years.
