SpaceX’s Falcon 9 rideshare program secures its first customer
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).
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 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.

SpaceX plans to attempt what will be a defining moment in rocket reusability on Starship Flight 15.
As Elon Musk announced in a recent X post, SpaceX will attempt to catch both the Super Heavy Booster and the Starship upper stage during the upcoming orbital flight. If successful, it will mark the first time that all parts of an orbital rocket return to Earth intact, a breakthrough Musk has called essential to making life multiplanetary.

Previous flights have demonstrated the tower-catch technique with Super Heavy. SpaceX has successfully caught V1 boosters three times (on Flights 5, 7, and 8), with some even reflown. The Ship upper stage has never been caught.
Returning from orbital velocity after deploying payload makes it a significantly harder challenge due to higher energy, heat loads, and the need for precise belly-flop reentry, a flip maneuver, and a final landing burn to settle between the Mechazilla tower’s chopstick arms.
Flight 15, using Booster 22 and Ship 42 (both Block 3 vehicles), is targeted for no earlier than Friday, November 13, 2026, from Orbital Launch Pad 2 at Starbase, Texas. The 75-minute window opens at 4:45 p.m. CT, pending regulatory approval. After hot staging and separation, the booster is planned to return for a catch roughly 6 minutes and 35 seconds after liftoff.
The Ship will insert into a roughly 275 km orbit, deploy 26 advanced Starlink V3 satellites, complete about 14 orbits over more than 22 hours, and—if systems check out—perform a deorbit burn, reentry, flip, and landing burn for a tower catch at approximately T+22 hours 32 minutes.
SpaceX confirms Starship 15 launch window with massive ambitions
A simulation shown during SpaceX’s October earnings call depicted the Ship descending in a belly-flop attitude, flipping upright with a short engine burn, and being captured by the arms:

SpaceX is just ONE WEEK away from attempting its most ambitious Starship catch yet https://t.co/nHrxSX6DSz

Contingency splashdown zones exist in the Gulf of Mexico (booster) and Pacific (Ship) if a catch is not viable. SpaceX has stressed rigorous health checks before committing the Ship to a return-to-launch-site trajectory.
Musk has described the odds of success on this first dual-catch attempt as “more likely than not,” noting a steady stream of additional flights is already scheduled if needed. Full recovery would enable rapid inspection, refurbishment, and reflight—slashing costs and supporting the high launch cadence required for Starlink expansion, lunar missions, and eventual Mars settlement.
As Musk put it, this is “the critical breakthrough needed to make life multiplanetary.”
Tesla Cybercab is going to get some pretty substantial updates, including improvements to efficiency and a new color.
CEO Elon Musk said in a post on X on Saturday that Tesla would be working to refine the Cybercab even more, following the announcement during the week that the company would eliminate the Cybertruck lines within Giga Texas for more Cybercab manufacturing capacity.
“There are efficiency improvements coming that will allow for a 40kWh Cybercab pack,” Musk posted on X. “We will make this in liquid silver, so the colors are not too monotonous.”
There are efficiency improvements coming that will allow for a 40kWh Cybercab pack. We will make this in liquid silver, so the colors are not too monotonous.
The biggest thing most people fail to understand is that there are a very limited number of smart, dedicated people! They can only do so many things.
If we have to maintain a complex production line, supply chain and allocate engineering for Cybertruck, we can’t use those people or factory space and machinery for scaling Cybercab, which is the vehicle that will PROFOUNDLY transform the world of terrestrial transport!
— Elon Musk (@elonmusk) November 7, 2026
A new, more efficient model of the Cybercab will be engineered, which will only help Tesla’s profitability and margins, and it also boosts the argument for why the Cybertruck should be discontinued, at least from a business perspective.
The current Cybercab that operates in the Robotaxi platform in Austin, Texas, has a 48 kWh pack, and it sounds like Musk believes Tesla is on its way to introducing a version that has fewer cells but can manage the same workload thanks to engineering efficiencies.

Musk also doubled down on the decision to prioritize Cybercab production over Cybertruck, which is a decision that has been extremely polarizing within the community, and many fans have made it abundantly clear that they are not particularly pleased with the plans.
“If we have to maintain a complex production line, supply chain, and allocate engineering for Cybertruck, we can’t use those people or factory space and machinery for scaling Cybercab, which is the vehicle that will PROFOUNDLY transform the world of terrestrial transport,” Musk said.

Cybercab is obviously Tesla’s path forward in an automotive sense. It seems that Tesla is less concerned about catering to the passenger vehicle market and is more prone to focus on transforming passenger transportation in a way that prioritizes autonomy. However, this requires some sacrifice on Tesla’s end, and the Cybertruck is unfortunately a victim of this.
Cybercab holds an extremely crucial part of Tesla’s future. With the company already revolutionizing passenger transportation once, this is the next phase, and Cybercab is the path forward.

Tesla Robotaxi app update now tells riders if Cybercab is the better choice
Tesla’s Robotaxi app now shows ETAs, wait times and availability for Cybercab and Model Y.
Tesla has rolled out a new vehicle selection screen in its Robotaxi app, and it puts the numbers riders care about most in front of them before they book.
Version 26.11.0 of the app shows the estimated arrival time, the expected wait and current availability for each vehicle option on a single screen, according to a video shared by @gheeunit on X on November 7. Riders deciding between a Cybercab and a Model Y Robotaxi can now compare those figures side by side instead of picking a car first and learning how long it will take afterward.
Tesla first gave riders that choice on September 3, the day paid Cybercab rides began in Austin. The original version of the screen listed the Cybercab, which seats two, next to the Model Y, which seats four. A later build, 26.8.2, added a seating capacity indicator so groups knew which car would fit them. What it did not show was whether choosing the Cybercab meant standing on the curb a few extra minutes.
Newest version of @robotaxi app has a new vehicle selector UI for choosing between Cybercab and Model Y and shows you the fare for both simultaneously! https://t.co/7qoDQ0vACX — mantequilla 🧈 (@gheeunit) November 7, 2026
That question matters more now than it did two months ago. Tesla had 45 Cybercabs on the Texas DMV roster when rides started. By late October the state listed 573, alongside 631 Model Ys, and community trackers logged a record 1,576 Cybercab sightings across Austin on Halloween alone. With two large fleets sharing one service area, the closest car and the quickest pickup are not always the same vehicle.
Inline availability also changes what happens when demand spikes. If no Cybercab is free nearby, the rider sees that on the selection screen rather than after trying to book one.
For now the comparison is mostly an Austin feature. Riders in Dallas, Houston, Fort Worth and the Florida markets are still matched with Model Y vehicles, though Tesla said on its third quarter earnings call that Cybercab rides would launch in Dallas this month.
The update follows a steady run of smaller changes to the rider experience. Late last month Tesla brought a quiet mode that blacks out the cabin screen to Model Y Robotaxis after first testing it in the Cybercab, and it has stretched Austin service to run from 6 a.m. to 2 a.m.
The Cybercab side of that selection screen is about to get much busier. Elon Musk said this week that Tesla will wind down Cybertruck production at Gigafactory Texas around the middle of 2027 to make room for more Cybercab output, and Tesla has said it is aiming to get Cybercabs to customers by the end of this year.
Tesla has not published official release notes for version 26.11.0.
