NASA SLS rocket launches Orion spacecraft to the Moon
After years, months, days, hours, and minutes of waiting, NASA’s first Space Launch System (SLS) rocket has successfully lifted off from Kennedy Space Center and sent an Orion spacecraft on its way to the Moon.
Originally projected to launch by late 2016, SLS lifted off for the first time at 1:48 am EST (06:48 UTC) on November 16th, 2022. Once known as Exploration Mission 1 (EM-1), NASA’s SLS debut was renamed “Artemis I” when the Trump administration created the Artemis Program in 2017. By most measures a semi-modernized Apollo Program without a geopolitical race against the Soviet Union, the Artemis Program survived the election of a new president in 2020, and the SLS rocket’s debut has officially become the program’s first major mission to get off the ground.
That SLS rocket has had a very long journey to its first successful launch. Supplied by United Launch Alliance (ULA), the rocket’s small Interim Cryogenic Propulsion Stage (ICPS) – the stage responsible for orbital burns – was delivered to the Kennedy Space Center in November 2017. Boeing shipped the first Core Stage – SLS’ central liquid rocket booster – to Mississippi for proof testing in January 2020, and CS-1 completed that testing in March 2021 and was delivered to Florida by April 2021.
After almost 12 months of painstaking assembly, the first fully-assembled SLS rocket rolled out to Kennedy Space Center Launch Complex 39B (Pad 39B) and attempted its first on-pad wet dress rehearsal (WDR) test. Seven months, three partially-completed WDRs, and two aborted launch attempts later, everything finally came together on November 16th, 2022.
By all appearances, the first SLS launch went perfectly. Shortly before liftoff, SLS ignited four former Space Shuttle Main Engines, making sure they were performing as expected. Seconds later, the launch computer fully committed and ignited both of SLS’ Shuttle-derived solid rocket boosters (SRBs) – motors than cannot be shut down after they’re lit. Much like the Shuttle did, SLS leapt off the pad after SRB ignition.
Combined, NASA says its RS-25 liquid engines and SRBs produced up to 4000 tons (8.8M lbf/39,200 kN) of thrust at liftoff, making SLS the second most powerful rocket to ever leave the launch pad. Only the Soviet Union’s N1 rocket, which produced up to 4500 tons (9.9M lbf/44,100 kN) of thrust at liftoff, was more powerful. But unlike N1, which failed four times over four launch attempts, the first SLS rocket reached orbit as planned, making it the most powerful rocket ever successfully launched.
About two minutes after liftoff, both SRBs successfully separated from the Core Stage. Eight and a half minutes after liftoff, the Core Stage shut down its four RS-25 engines and deployed the ICPS and Orion spacecraft just below the height of a stable orbit. 51 minutes after liftoff, ICPS ignited its lone RL-10 engine for 22 seconds to insert itself and Orion into a stable Earth orbit. Finally, about an hour and forty minutes after liftoff, ICPS ignited for a lengthy 18-minute trans-lunar injection (TLI) burn, sending Orion on a trajectory that will intercept the Moon on November 21st.
If all goes according to plan, Orion will then use its own European Service Module (ESM) to correct its trajectory and enter a Distant Retrograde Orbit around the Moon on November 25th, where it will remain tens of thousands of kilometers above the lunar surface. Orion will then leave lunar orbit as early as December 1st and reenter Earth’s atmosphere on December 11th before the capsule finally splashes down in the ocean.
Assuming Artemis I goes perfectly, Artemis II – SLS and Orion’s first launch with astronauts aboard – is scheduled no earlier than (NET) 2024. Artemis III, which will team up with a modified version of SpaceX’s Starship launch vehicle to attempt to land astronauts on the Moon for the first time since 1972, is expected to follow NET 2025. However, a reliable source with a prophetic track record estimates that Starship and SLS might not be ready to launch Artemis III until 2028.

Tesla is sending its humanoid Optimus robot to the Boston Marathon
Tesla’s Optimus robot is heading to the Boston Marathon finish line
Tesla’s Optimus humanoid robot will be stationed at the Tesla showroom at 888 Boylston Street in Boston, right along the final stretch of the Boston Marathon today, ready to cheer on runners and pose for photos with spectators.
According to a Tesla email shared by content creator Sawyer Merritt on X, Optimus will be at the Boston Boylston Street showroom on April 20, coinciding with Marathon Monday weekend. The Boston Marathon finishes on Boylston Street, and the surrounding area draws hundreds of thousands of spectators along with international broadcast coverage. Placing Optimus there puts it in front of a massive public audience at zero advertising cost.
Just got this email. @Tesla’s Optimus robot is coming to Boston.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.
Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.
Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.

Tesla expands Unsupervised Robotaxi service to two new cities
This expansion builds directly on Tesla’s existing operations. Robotaxi has been ramping unsupervised rides in Austin for months and maintains activity in the San Francisco Bay Area.
Tesla has taken a major step forward in its autonomous ride-hailing ambitions.
On April 18, the company’s official Robotaxi account announced that Robotaxi service is now rolling out in Dallas and Houston, Texas. The update signals the rapid scaling of unsupervised autonomous operations in the Lone Star State.
The announcement includes a compelling 14-second video captured from inside a Model Y. Shot from the passenger perspective, the footage shows the vehicle navigating suburban roads in both cities with zero driver intervention, with no Safety Monitor to be seen.

This expansion builds directly on Tesla’s existing operations. Robotaxi has been ramping unsupervised rides in Austin for months and maintains activity in the San Francisco Bay Area.
With Dallas and Houston now live, Texas hosts three active hubs—an impressive concentration that triples the company’s Lone Star footprint in just weeks. The move aligns with Tesla’s Q4 2025 earnings guidance, which outlined a broader H1 2026 rollout across seven U.S. cities, including Phoenix, Miami, Orlando, Tampa, and Las Vegas.
Texas offers favorable regulations, high ride-share demand, and relatively straightforward suburban-to-urban driving patterns ideal for early autonomous scaling. While initial geofences appear modest—roughly 25 square miles per city—Tesla has historically expanded these zones quickly as it gathers real-world data.
Tesla confirms Robotaxi expansion plans with new cities and aggressive timeline
Unsupervised operation marks a critical milestone: passengers can summon, ride, and exit without safety drivers, a leap beyond many competitors still requiring human oversight.
For Tesla, the implications are significant. Successful scaling in major metros could accelerate the transition to a fully driverless fleet, unlocking new revenue streams and validating years of Full Self-Driving investment.
Riders gain convenient, potentially lower-cost mobility, while the company edges closer to Elon Musk’s vision of Robotaxis transforming urban transport.
As Tesla pushes into more cities this year, today’s launch in Dallas and Houston underscores its momentum. Hopefully, Tesla will be able to expand unsupervised rides to another U.S. state soon, which will mark yet another chapter in this short-but-encouraging Robotaxi story.

Tesla is pushing Robotaxi features to owner cars with Spring Update
Tesla has quietly begun rolling out one of its most forward-looking Robotaxi-inspired features to existing customer vehicles.
Tesla is starting to push Robotaxi features to owner cars, and the first instances are coming as the Spring 2026 Update starts to roll out.
Tesla has quietly begun rolling out one of its most forward-looking Robotaxi-inspired features to existing customer vehicles.
With the 2026 Spring Update (version 2026.14+), the rear passenger display now features a fully interactive navigation map that works while the car is driving — a capability previously reserved for Tesla Robotaxi.
First look at Tesla’s v2026.14.1 Spring Update.

Until now, Tesla’s rear displays have been largely limited to media controls, climate settings, and static route overviews. The new interactive map transforms the backseat into an active navigation hub, exactly the kind of passenger-first interface Tesla has been prototyping for its driverless fleet.
In a Robotaxi, where no one sits behind the wheel, every rider will need intuitive, real-time map access. By shipping this UI into thousands of owner cars months ahead of the Cybercab’s planned unveiling, Tesla is stress-testing the software in real-world conditions and giving loyal customers an early taste of the autonomous future.
The rollout is still in its early wave. Only a small number of vehicles have received 2026.14.1 so far, but the feature is expected to expand rapidly in the coming weeks. Owners of Model S, Model X, Model 3, Model Y, and Cybertruck are all eligible.
For buyers of the new Signature Edition Model S and X Plaid vehicles — whose deliveries begin in May — the update will likely arrive shortly after they take delivery, meaning the final chapter of Tesla’s flagship lineup will ship with cutting-edge Robotaxi preview tech baked in.
Elon Musk has long emphasized that Tesla ships supporting infrastructure well before new products launch. This rear-map rollout is a textbook example of that philosophy — quietly preparing both the software and the customer base for a world of fully driverless rides.
While the interactive map may seem like a modest convenience upgrade on the surface, its deeper purpose is unmistakable. Tesla is using its massive installed base of vehicles as a proving ground for the exact passenger experience that will define the Robotaxi era.
For current owners, it’s a free preview of tomorrow’s mobility; for the company, it’s invaluable data and real-world validation before the Cybercab hits the streets.
