In his latest burst of tweets, SpaceX CEO Elon Musk says he isn’t all that worried about a duo of recent Starship prototype failures and talked next steps for the next few Starships.

Aside from SpaceX’s South Texas rocket factory, Musk also touched on progress being made on the cutting-edge Raptor engine set to power Starships and their boosters, revealing a small production milestone in the process. The CEO says that SpaceX has already begun building its 26th Raptor engine, a sign that Raptors may actually be waiting on Starships in a turn of events. Back when SpaceX was busy testing its low-fidelity Starhopper testbed, the ship actually had to wait several months for the full-scale Raptor engine’s design to mature enough to support 15-30+ second hop tests.

Now, Musk’s Raptor SN26 reveal implies that SpaceX is slowly but surely ramping up production of the new engine back at its Hawthorne, California headquarters.

From August to December 2019, SpaceX completed one Raptor engine every ~17 days, on average. With Musk’s confirmation that SpaceX is currently building (or already testing) SN26, the company is completing an engine every 12-14 days – an overall improvement of 20-40%. In other words, SpaceX’s growing engine production capacity is almost perfectly positioned to support a fleet of suborbital Starship prototypes, which is about where the company’s Boca Chica, Texas factory is today.

Obviously, following two recent full-scale Starship prototype failures spaced barely a month apart, rocket production has a ways to go before it will need the volume of Raptor engines SpaceX appears to already be capable of producing. For the time being, three Raptor engines – having already completed production in Hawthorne and acceptance testing in McGregor, Texas – are quite literally sitting around and gathering dust as they wait for the first Starship prototype qualified to host them.

Once a Starship passes proof testing, SpaceX will be able to install either one or all three engines for an inaugural static fire test, following by a small Starhopper-class hop (no higher than 150m or 500 ft).

However, once SpaceX has explored the full range of testing available to suborbital Starship prototypes, things will change. Likely ending with the first one or several successful ‘skydiver-style’ rocket landing tests, SpaceX will finally be able to seriously think about its first orbital flight tests. To reach orbit and still be capable of returning to Earth and landing softly, Starship will need a Super Heavy booster – set to be the largest rocket booster ever developed by a large margin.

Although Musk has stated that early orbital flight tests will likely launch with far fewer engines, a single Super Heavy booster could eventually require 37 Raptor engines – a full 42% more engines than SpaceX has managed to build in the entire 15+ month history of full-scale Raptor production.

Thankfully, SpaceX’s engine production HQ likely has at least 6-12 months to ramp up production to support fully-outfitted Super Heavy boosters – let alone several. For the time being, each suborbital Starship only needs 3 sea level-optimized Raptor engines, although it’s possible that SpaceX will eventually perform suborbital tests with a full compliment of six engines – including three with much larger vacuum-optimized nozzles.

Ultimately, Musk explained that his lack of concern about recent Starship prototype failures – potentially including any anomalies that follow SN4’s test campaign – comes from the fact that he believes that producing Starships is a much more challenging and pressing concern. Indeed, if your factory can churn out functioning building-sized spacecraft for pennies on the dollar, losing a few during testing is little more than an annoyance. The first failed prototypes can thus be considered learning experiences, helping SpaceX improve designs and optimize the factory and production strategies. SpaceX does still need to prove that its existing approach really can build functioning rockets, but that should (in theory) come with enough trial and error.

Depending on how initial tests go with Starship Serial Number 4 (SN4), likely days away from wrapping up production, Musk says that the first few suborbital Starship tests will likely involve short, low-velocity hops. Those flights will be slow enough that the ship (or ships) wont require aerodynamic control surfaces to complete them, instead relying entirely on smaller thrusters and the thrust vector control (TVC) provided by their three main Raptor engines.

If Starship SN4 testing – including wet dress rehearsals, Raptor static fires, and short hops – goes perfectly, Musk says that Starship SN5 could be the first new ship to have fully-functional flaps installed. If things don’t go quite as well, that milestone could shift to Starship SN6, while SN7 and beyond are obviously on the table in the event of even less forgiving SN4/SN5 testing scenarios. For now, Starship SN4 could be ready to move to the launch pad and kick off a series of critical proof tests a handful of days from now.

Tesla expands Robotaxi in a way that was long anticipated

Instead, it has to do with the consumer base it offers Robotaxi to, because it has not offered it to everyone in the past.

Tesla has expanded Robotaxi in a way that was long anticipated, and it does not have to do with a new, larger geofence in a city where it already offered its partially autonomous ride-hailing suite, or a new city altogether.

Instead, it has to do with the consumer base it offers Robotaxi to, because it has not offered it to everyone in the past.

Tesla has taken a major step forward in its autonomous ride-hailing ambitions with the official launch of the Tesla Robotaxi app for Android users. Released on the Google Play Store on April 24. Titled simply “Tesla Robotaxi,” the app is now available to download directly from Tesla.

This rollout fulfills a long-anticipated expansion that opens the service to hundreds of millions of Android smartphone users who were previously unable to access it on iOS alone.

The app delivers a streamlined, driverless ride experience powered by Tesla’s automated driving technology.

Users sign in with a Tesla Account, view the current service area map within the app, enter a destination, and receive an estimated fare and arrival time before confirming the ride. When a Model Y from the Robotaxi fleet arrives, riders confirm the license plate, enter the vehicle, fasten their seatbelt, and tap “Start Ride” on either the app or the vehicle’s touchscreen.

During the trip, passengers have access to all the same controls that iOS users do, and can adjust climate settings, seat positions, and music while tracking progress on an in-app map. The interface also allows drop-off changes or support requests if needed. After the ride, users exit, close the doors, and submit feedback.

This Android availability directly broadens the rider base for Robotaxi in its initial service areas. Unfortunately, Android users are used to being subject to delayed launches of new features available to Tesla owners.

By removing the iOS-only barrier, Tesla instantly expands the addressable market, enabling far more people to summon and use the autonomous vehicles already operating on public roads.

The move is a foundational requirement for scaling ride volume and gathering the real-world data needed to refine the unsupervised Full Self-Driving system that powers every trip.

For the Robotaxi program itself, the launch signals steady operational progress. It prepares the service for higher utilization rates as the fleet grows and supports the transition from limited early deployments to a more robust network.

Tesla expands Unsupervised Robotaxi service to two new cities

Tesla has indicated that users outside current service areas can sign up at the company’s website for future notifications, pointing to a deliberate, phased geographic rollout.

Looking ahead, the company plans to incorporate Cybercab vehicles to increase fleet capacity and efficiency while continuing to expand service territories. With the Android app now live, Tesla has removed a key adoption hurdle and positioned Robotaxi for the next phase of growth in autonomous urban transportation.

The infrastructure is now in place to support significantly larger rider demand as production and deployment accelerate.

UPDATE: SpaceX’s Falcon Heavy that launched a Tesla into space is back on a mission

SpaceX Falcon Heavy returns after 18 months away to deliver a satellite that only it could carry.

UPDATE: 10:29 a.m. et: SpaceX is standing down from today’s Falcon Heavy launch of the ViaSat-3 F3 mission due to unfavorable weather. A new target date will be shared once confirmed.

After an 18-month absence, SpaceX’s Falcon Heavy is returning to mission on Monday morning when it’s scheduled to lift off from Launch Complex 39A at Kennedy Space Center at 10:21 a.m. EDT.

The mission is called ViaSat-3 F3, and the heavy satellite payload needs to reach geostationary orbit, sitting 22,236 miles above Earth where its speed matches the planet’s rotation. Getting a satellite that heavy to that altitude demands more thrust than a single-core Falcon 9 can deliver.

This marks the Falcon Heavy’s 12th flight overall since its debut in February 2018, and its first since NASA’s Europa Clipper mission in October 2024.

Arguably, the most exciting element for spectators will be watching the booster recoveries in action when the two side boosters, B1072 and B1075, will attempt simultaneous landings at Landing Zone 2 and the newer Landing Zone 40 at Cape Canaveral Space Force Station, while the center core will be expended over the ocean.

SpaceX wins its first MARS contract but it comes with a catch

Following satellite deployment, expected roughly five hours after launch, ViaSat-3 F3 will spend several months traveling to its final orbital slot before undergoing in-orbit testing, with service entry expected by late summer 2026

As Teslarati reported, NASA awarded SpaceX a $175.7 million contract on April 16, 2026, to launch the ESA Rosalind Franklin Mars rover aboard a Falcon Heavy no earlier than late 2028, which would mark the first time SpaceX has ever sent a payload to Mars. That contract came on top of an already deep pipeline that includes the Roman Space Telescope, the Dragonfly Saturn mission, and multiple national security payloads.

SpaceX executed 165 missions in 2025 and now accounts for approximately 85% of all global orbital launches. With Starlink surpassing 10 million subscribers and an IPO targeting a $1.75 trillion valuation still ahead, Monday’s launch is one more data point in a company that has quietly become the backbone of both commercial and government space access worldwide.

Tesla launches solution to end Supercharger fights once and for all

Published

Tesla is launching its solution to end Supercharger fights once and for all, eliminating any confusion on who is to charge next at a congested location.

Last year, a notable incident at a Tesla Supercharger led to a fight, and it all stemmed from a disagreement over who arrived at the location first.

Congestion at Tesla Superchargers is a pretty infrequent occurrence for most of us, but there are more congested and popular areas where wait times can be extensive. An unfortunate growing pain of EV ownership is the plain fact that chargers are not as available as gas pumps, and there are, at times, lines to charge.

This can cause tensions to flare and people to get entitled when visiting Superchargers. Nobody wants to spend hours at a Supercharger, but now, there will be no more confusion when there is a queue, and that’s thanks to Tesla’s new Virtual Queue for Superchargers.

Tesla is finally starting to build out the Virtual Supercharger Queue, according to Not a Tesla App, but it still relies on drivers to make it work.

When a driver is near a Supercharger that is full, a message will pop up on the Tesla App, using the driver’s location to determine their eligibility to join the virtual queue.

The app states:

“While the app is closed, Tesla uses your location to notify you of accurate wait times at Superchargers when you arrive.”

Another message within the app states:

“There is a waitlist to charge. Are you sure you want to start a charging session now?”

This sounds as if it will require drivers to act appropriately and only plug in when the app prompts them to do so, by letting them know it is their turn.

The app will notify the driver of their position in the queue, as well as how many vehicles are ahead of them.

Tesla launches first ‘true’ East Coast V4 Supercharger: here’s what that means

The company announced a while back that it would be working on a solution for this issue. Personally, I’ve only had to wait at a Supercharger for a charge on one occasion, and there was a line of between 3 and 10 cars during this singular occurrence.

There were no conflicts or arguments about who had arrived first, but there was some discussion between several drivers during my time there about who was to charge first. Throw a non-Tesla EV into the mix, one that can only charge at a pull-in spot, and that causes even more of a complication.
