SpaceX has finished stacking its fourth full-scale Starship prototype and public schedules show that the rocket could be moved to a nearby launch and test pad as early as April 20th.

Known as Starship serial number 4 (SN4), the rocket will be the third full-scale vehicle completed since the start of serial production, while Starship Mk1 – the first full-scale prototype – was built far more slowly and with different methods. Mk1 was destroyed during one of its first cryogenic liquid nitrogen ‘proof’ tests in November 2019, nearly nine months after assembly began in February. After Mk1’s failure, SpaceX spent about two months rapidly expanding and upgrading its Boca Chica, Texas Starship factory.

Around the end of January 2020, SpaceX kicked off the production of its first serial prototype – logically deemed SN1. Less than a month after its first steel rings were stacked and welded together, SpaceX transported the completed prototype to the launch pad. On February 28th, what CEO Elon Musk later described as a fault in its engine section “thrust puck” destroyed Starship SN1 during one of its first cryogenic proof tests. Barely a month later and after SN2 was modified into a “thrust puck” test tank and successfully tested, Starship SN3 rolled to the launch pad and was destroyed by operator and test design errors on April 3rd. Now, barely two weeks after SN3, Starship SN4 is about to begin testing.

By all appearances, work on Starship SN4 began around March 23rd, continuing a production schedule that has been consistently completing a full-scale rocket prototype every four or so weeks. While SpaceX has taken the unprecedented step of reusing a section of a prototype (SN3) destroyed during testing, every other aspect of the rocket is new and built more or less from scratch.

Starship SN3’s skirt – including internal plumbing, landing legs, and more – was removed from the rest of the ship’s remains and moved back to the build site on April 7th. (NASASpaceflight – bocachicagal)

Just two days after Starship SN3’s salvaged skirt and SN4’s new engine section and aft liquid oxygen tank dome were stacked and welded together, SpaceX technicians attached a crane to the upper two-thirds of the rocket’s tank section and stacked it on top of the newly-finished engine section. 24 hours later, SpaceX teams have completed at least one circumferential seam weld, with a second soon to be finished.

Once that last weld is complete and passes inspections, Starship SN4 will be ready to be lifted onto a transporter and rolled down the road to SpaceX’s dedicated launch and test facilities. Of course, like SN3 and SN1 before it, SpaceX will likely still have a few days of work to get Starship SN4 ready for testing once it’s been moved to the pad.

Using Starship SN3’s timeline, Starship SN4 could be transported to the pad as early as April 19th or 20th and ready for testing by April 24th or 25th. This meshes well with a publicly-available road closure schedule, required because SpaceX often needs to close a public highway for certain Starship transport and testing operations. Per Cameron County’s website, SpaceX has a transport-related closure planned on April 20th. The first testing-related closure begins on Sunday, April 26th and lasts from 9am to midnight, with backups on Monday and Tuesday.

As always, delays should come as no surprise with prototype testing, and schedules are always fluid and liable to change at any second. Regardless, it looks like Starship SN4 is perhaps just a week from its first round of testing.

SpaceX achieves incredible milestone with Starlink program

Published

SpaceX has achieved an incredible milestone by launching its 11,000th Starlink satellite into orbit.

This accomplishment occurred during the Starlink Group 17-50 mission, which lifted off on August 19 at 04:01 UTC from Space Launch Complex 4 East at Vandenberg Space Force Base in California.

A Falcon 9 rocket carried 24 Starlink V2 Mini satellites on this flight, successfully deploying them into low Earth orbit approximately one hour after liftoff. The first stage booster, identified as B1097 on its twelfth flight, landed successfully on the droneship Of Course I Still Love You in the Pacific Ocean.

According to tracking data compiled around that date, this deployment brought the total number of Starlink satellites in orbit to just over 11,000.

The Starlink program began with test satellites known as Tintin A and B, launched on February 22, 2018. The first operational batch of 60 Starlink satellites followed on May 24, 2019, when a Falcon 9 rocket lifted off from Cape Canaveral. Those initial satellites marked the start of a rapid expansion that has continued for more than seven years.

SpaceX has conducted hundreds of dedicated Starlink missions since then, routinely launching batches of 20 to 30 satellites at a time using reusable Falcon 9 rockets. By mid-2026, the company had already surpassed 12,000 total satellites launched across all versions, with continuous replacements for units that deorbit as designed to manage space debris.

Looking ahead, SpaceX continues to expand the Starlink constellation to enhance global broadband coverage, capacity, and speed. The network already serves millions of users across more than 160 countries and supports applications ranging from residential internet to maritime, aviation, and emergency services.

Future plans center on next-generation hardware, including larger V3 satellites capable of delivering substantially higher throughput, which require the increased payload capacity of the Starship vehicle currently under development and testing.

In July, SpaceX submitted an application to the Federal Communications Commission seeking authority for a Gen3 constellation of up to 100,000 satellites. These spacecraft would operate in very low Earth orbit shells at altitudes near 325 kilometers and 475 kilometers. The filing requests use of existing Ku, Ka, V, and E band spectrum along with new greenfield W and D band frequencies between 92 and 275 GHz.

SpaceX states that the expanded system aims to deliver multi-gigabit symmetrical broadband to consumers, enterprises, governments, and billions of AI-powered devices worldwide while handling a majority of global internet traffic. Approval and subsequent deployment would depend on regulatory review and the operational readiness of Starship for high-volume launches.

This ambitious scale reflects SpaceX’s ongoing commitment to providing ubiquitous high-speed connectivity from space.

Tesla is opening Cybercab rides to a select few

Tesla has opened a new sweepstakes to allow the public to be among the first to take an initial ride in a Cybercab. This all-electric, steering-wheel-less, pedal-less vehicle is the centerpiece of the company’s autonomous ride-hailing platform, Robotaxi.

There are two ways Tesla fans can get to Austin to take part in the first public rides of the Cybercab: by riding on the Robotaxi platform by August 23, or by mailing a very specific entry to their Headquarters at Gigafactory Texas.

Tesla announced the latter portion of the sweepstakes last night:

Tesla will give one entry into the sweepstakes if you mail a 3″ by 5″ piece of paper with your full name, mailing address, telephone number, email address, and date of birth to their address:

Tesla, Robotaxi Sweeps Event

1 Tesla Road,

Austin, TX 78725

There is a limit of one entry per stamped envelope. You can send as many as you’d like, but they must be in separate envelopes.

The company’s unique strategy to give people the opportunity to ride in a Cybercab before pretty much anyone else outside of the company is a hilarious but spot-on representation of how Tesla operates. In classic fashion, they had the perfect response to the event:

Cybercab will launch later this month, it appears, especially as it plans to announce the winners of the sweepstakes on August 25. The car has already been operating internally, as employees have been able to utilize the Cybercab for rides in some capacity, something it announced earlier this month.

Tesla weirdly confirms Cybercab employee rides, a huge milestone

Moving forward, the big goal is to get Cybercab out on the roads and integrated into the public Robotaxi fleet, one that will pick up real-world ride-hailers and give them a ride from Point A to Point B.

No matter which way you cut it, it appears Tesla is close to putting a vehicle with no steering wheel and no pedals on the road to help people travel autonomously.

You can ride along with us in our first Cybercab ride from the We, Robot event in October 2024. The video is embedded below:

Tesla reveals plans for Robotaxi charging hub in Austin

Tesla has revealed plans through permit submissions for a massive Robotaxi charging hub in Austin, Texas.

Tesla plans to build the Supercharger hub in multiple phases, with the second phase potentially introducing wireless induction charging, something the company has been developing for the Robotaxi fleet.

Initially, 48 Tesla Robotaxi-geared Superchargers will be built on a lot just across from the St. Elmo, Texas, Service Center. There are about 80 additional spots that will not be impacted by phase 1 of the construction process.

Filings show that the second phase of the project will turn those 80 additional spots into wireless charging for Robotaxi, but it might be an error. The Key Notes state that item 3 is listed as “V4 Charging Cabinet to Support 80 Wireless Chargers in Phase 2. However, the drawings point to V3 Cabinets that are already tied to Superchargers:

There are roughly 128 total spots in the lot, but it is unclear if they will all be used for charging based on what appears to be some sort of typo in the blueprint.

This is among the first Robotaxi charging hubs Tesla has started to develop, as it currently has four others planned throughout various areas: one in Phoenix, one in San Antonio, another in Irving, which will serve the Dallas-Fort Worth area, and another in Las Vegas.

These projects are necessary as Tesla expands its Robotaxi program. Now that preparations have started for the public launch of Cybercab, Robotaxi will likely be expanding aggressively, especially over the next two to three years.

Last night, The Information reported that Tesla was planning to launch Cybercab as soon as the end of August. Hours later, Tesla then announced it was launching a competition for fans to potentially ride in Cybercab during its first public rides.

Tesla Cybercab launch preparations have begun

Tesla’s plan to expand its charging infrastructure in the regions where Robotaxi will initially operate is great preparation for the expanding service. There is still a lot to do, including launching the Cybercab on time.
