SpaceX rocket performs first last-second launch abort in years, delaying Starlink mission

A Falcon 9 rocket has performed SpaceX’s first last-second launch abort in years, shutting down the booster’s main engines and preventing liftoff just milliseconds after ignition.

Scheduled to lift off at 9:22 am EDT (13:22 UTC) on March 15th, SpaceX will now wait until no earlier than (NET) 8:21 am EDT (12:21 UTC) on Wednesday, March 18th for the sixth 60-satellite Starlink mission’s next launch attempt. Featuring an exceptionally flight-proven Falcon 9 booster and marking the second time ever SpaceX has reused a payload fairing, yesterday’s launch abort is also unique in its own right.

Notably, shortly after the launch countdown froze and Falcon 9 shut down at T-00:00:00, a launch operator – on-console either in Florida or at SpaceX’s Hawthorne, CA headquarters – revealed that the rocket had triggered a “launch abort on engine high power”. To explain that decision, a little background on how SpaceX launches its rockets and what exactly abort conditions are is necessary.

Software has always been a central part of SpaceX’s launch vehicles, treated more like a first-class citizen in design and engineering instead of the reluctant necessity other launch providers have frequently relegated it to. For anyone that’s watched numerous SpaceX launch webcasts, some might recognize the familiar “vehicle is in startup” callout that made around T-1 minute to liftoff. Standard on most modern launch vehicles, SpaceX’s Falcon rockets use onboard computers to take over their countdowns shortly before launch.

This is mainly done to allow the vehicle to simultaneously analyze thousands of channels of telemetry far faster and more reliably than humans ever could. During today’s launch attempt, that meant that Falcon 9 saw something it didn’t like just milliseconds before it was scheduled to command the release of the pad’s hold-down clamps and lift off.

Per one of SpaceX’s on-console engineers, the specific issue Falcon 9’s computer flagged was an “engine high power” alert. Soon after, SpaceX provided an update on Twitter, stating that the abort was “triggered due to out-of-family data during [an] engine power check” – putting the blame more on the sensors and software used to determine engine thrust than the engine hardware itself. An actual hardware or software failure that caused one or several booster engines to exceed their design limits could have potentially damaged B1048’s Merlin 1Ds, likely requiring weeks of repairs or a full swap with a different booster.

Given that Falcon 9 B1048 has already performed four orbital-class launches, hardware issues would not come as a major shock, but the successful static fire test it completed on Saturday made that far less likely. SpaceX’s confirmation that it was looking at an “out-of-family” reading thankfully means that only one of several thrust sensors showed the Falcon 9 booster producing too much thrust.

With any luck, post-ignition launch aborts will continue to be extremely rare for SpaceX’s Falcon launch vehicle family. The last such abort occurred in February 2016, more than four years and several booster ‘Block’ iterations ago.

Starlink L6 (V1 L5) is now scheduled to launch on Wednesday, March 18th, giving SpaceX workers some 72 hours to inspect Falcon 9 B1048’s engines, replace thrust sensors, tweak software, and prepare for a second launch attempt. Drone ship Of Course I Still Love You (OCISLY), fairing recovery ships GO Ms. Tree and GO Ms. Chief, and another support vessel or two remain on station in the Atlantic Ocean and will have to wait a bit longer for their next rocket recovery attempts.

Tesla expands Robotaxi to Florida, marking its third state for autonomy

Published

Tesla has expanded its Robotaxi program to Miami, Florida, marking the third state the autonomous ride-hailing platform has made its way to since launching last Summer.

Tesla announced today that the Robotaxi suite would now officially launch rides in a geofence in Miami:

The first geofence in Miami covers approximately 10 to 14 square miles. The area appears to be focused on western and central Miami, including Miami International Airport (MIA). It also includes popular routes like SR 826 (Palmetto Expressway), US 41 (Tamiami Trail), and connectors such as SR 968, 953, 959, and 972.

This is Tesla’s initial Miami launch zone, smaller and more targeted than some competitors’ areas (for example, Waymo’s initial rollout was broader in eastern neighborhoods). It prioritizes high-traffic, airport-linked routes before wider expansion.

The expansion is a huge signal for Tesla that it is now operating in Florida, a heavy-traffic state with many tourist areas, including Fort Lauderdale, Palm Beach, and the Boynton area, all of which are coastal and will attract perhaps millions of tourists in any given year.

The Tesla Robotaxi network launched last year on June 22, in Austin, Texas, beginning limited commercial operations in that city. It expanded shortly thereafter into the San Francisco Bay Area of California in late July 2025, marking entry into a second state with service covering key areas such as San Francisco, San Jose, and Berkeley.

Full commercial service was achieved in Austin by November 18, 2025, strengthening its presence within Texas before further growth.

In 2026, the network continued expanding across Texas with the addition of Dallas and Houston on April 18, significantly broadening its footprint in the state. This new launch into Miami marks Tesla entering a new state and bringing active locations to include Austin, Dallas, Houston, San Antonio in Texas, and the Bay Area in California.

These sequential expansions have steadily increased the network’s reach across major metropolitan areas in Texas, California, and Florida, focusing on scaling operations city by city and state by state since the initial Austin debut.

Elon Musk outlines Tesla Optimus production expectations

Published

Tesla CEO Elon Musk has tempered expectations for the company’s humanoid robot Optimus, emphasizing that initial production will ramp up slowly despite recent progress on the manufacturing line. In a July 1 reply on X, Musk responded to optimistic community speculation by stating, “No, Optimus production will be extremely slow at first, as everything is new. This is not like making a car.”

The comment came in response to a post theorizing that Tesla had accelerated Optimus V3 development and might soon unveil an impressive demonstration with multiple units already in meaningful production. Musk’s clarification highlights the fundamental differences between scaling a novel humanoid robot and Tesla’s established automotive operations, which benefit from over a century of refined supply chains, tooling, and processes.

Recent updates show tangible advancement. Musk shared a photo of himself walking the Optimus production line at Fremont, where Tesla is converting former Model S/X manufacturing space. According to Q1 2026 earnings commentary, limited production is slated to begin in late July or August 2026 on this converted line.

Tesla Optimus project fires up as Musk sees production line progress

Musk previously noted that Optimus features roughly 10,000 unique parts, making early output rates “literally impossible to predict” and describing them as “quite slow.” A larger dedicated factory at Giga Texas is under construction, targeting higher-volume production around summer 2027 with long-term annual capacity potentially reaching millions of units.

Some experts point out that pioneering humanoid robotics demands inventing new automation techniques, actuator supply chains, and quality-control standards in real time. Unlike vehicles, where components and assembly methods are mature, every element of Optimus—from dexterous hands to AI-integrated movement—requires fresh engineering solutions. Early units are expected to handle simple factory tasks before expanding to more complex roles.

This cautious approach aligns with Tesla’s history of under-promising and over-delivering on complex technologies. While enthusiasts hoped for rapid deployment, Musk’s message underscores a deliberate strategy: prioritize reliability and iterative improvement over rushed volume.

Analysts suggest the S-curve ramp typical of new manufacturing will eventually accelerate once foundational issues are resolved, positioning Optimus as a potential trillion-dollar product line.

Musk has long envisioned Optimus transforming labor markets, assisting in homes, factories, and hazardous environments. By setting realistic timelines, Tesla aims to build sustainable momentum rather than risk disappointment. As the Fremont line comes online this summer, investors and fans will watch closely for the first production metrics and capability demonstrations.
