SpaceX aces fourth Starship flight test
SpaceX successfully launched and landed its Super Heavy booster and Starship on its fourth integrated flight test, with each making a soft splashdown in the water.
Starship took to the skies at 7:50 am CT from a foggy Starbase, Texas, in an effort to surpass previous flight milestones.

As the countdown hit zero, 32 of 33 Raptor engines on the Super Heavy booster lit, with the outlier being an engine on the outer ring. Despite the engine out, the booster still ascended with ease away from the launch mount and broke through the thick fog into clear blue skies with views streamed back to the ground from just above one of the grid fins.
As Starship climbed, everything continued to operate nominally all the way through the hot staging which saw Super Heavy Booster 11 shut down all but its 3 center Raptor engines as Starship 29 lit its 6 Raptor engines to pull away from the massive booster. As soon as Starship was clear, Booster 11 completed a flip and boostback burn to begin its trip for a planned soft touchdown in the Gulf of Mexico by relighting 10 Raptor engines.
Once the boostback burn was complete, the hot staging ring was ejected to reduce the overall mass of the booster to help it survive reentry and landing. Future Super Heavy boosters will feature a lighter hot staging ring that will not be ejected. As the booster made its way back, it re-orientated to vertical and began re-entry back through the atmosphere, and unlike the Falcon 9, it does not perform an entry burn.

At around 7 minutes and 15 seconds into flight, the Super Heavy booster lit 12 out of a planned 13 engines for its landing burn, followed shortly by quite a bit of debris flying by the onboard camera, but it did not affect anything critical as seconds later Booster 11 made a successful splashdown in the Gulf of Mexico before a slow planned tip over into the water.

As Booster 11 completed the first successful soft landing, Starship 29 fired its six Raptor engines, three sea level and three vacuum, with engine shutoff coming in at eight and a half minutes into flight. The starship then entered a long coast phase as it passed between the Florida Keys and Cuba and transited over the Atlantic Ocean, followed by Africa.
During IFT-3, live views were provided for a majority of this portion but due to an unknown issue, cameras didn’t come back until just before 37 minutes into the flight. Elon Musk posted on X that they had a data signal the entire time including live views from internal cameras.
45 minutes into the flight, the true test of Starship began as plasma started to build up, but this time, Starship was in the correct orientation, and the heatshield was facing the correct way to give the ship its best chance at survival.
As Starship descended, plasma build-up increased with callouts from mission control noting rising temperatures on the nose but all within acceptable limits. At just over 54 minutes into the flight, Starship made it further than the third flight test and into unknown territory.

57 minutes into the flight, peak heating had passed but tiles were starting to fall away from the forward flap followed by melting of the lower portion, despite this damage, Starship held strong and in the correct orientation as it descended.
Starship continued its descent and, with significant damage, still made it through to its own landing burn and performed its flip to a vertical orientation and a soft touchdown in the Indian Ocean west of Australia.

Even with the damage inflicted on Starship, it completed all test objectives while providing SpaceX with incredibly valuable data that will be used to make the ship stronger on future test flights. The Starlink antenna also survived the entire flight which ensured this data made it back to mission control.
With this successful mission complete, SpaceX could launch the 5th flight by mid to late July and possibly even attempt a catch of the Super Heavy booster according to Elon Musk.

Tesla hosts Rome Mayor for first Italian FSD Supervised road demo
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets.
Tesla definitely seems to be actively engaging European officials on FSD’s capabilities, with the company hosting Rome Mayor Roberto Gualtieri and Mobility Assessor Eugenio Patanè for a hands-on road demonstration.
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets. This comes amid Tesla’s push for FSD’s EU regulatory approvals in the coming year.
Rome officials experience FSD Supervised
Tesla conducted the demo using a Model 3 equipped with Full Self-Driving (Supervised), tackling typical Roman traffic including complex intersections, roundabouts, pedestrian crossings and mixed users like cars, bikes and scooters.
The system showcased AI-based assisted driving, prioritizing safety while maintaining flow. FSD also handled overtakes and lane decisions, though with constant driver supervision.
Investor Andrea Stroppa detailed the event on X, noting the system’s potential to reduce severe collision risks by up to seven times compared to traditional driving, based on Tesla’s data from billions of global fleet miles. The session highlighted FSD’s role as an assistance tool in its Supervised form, not a replacement, with the driver fully responsible at all times.
Path to European rollout
Tesla has logged over 1 million kilometers of testing across 17 European countries, including Italy, to refine FSD for local conditions. The fact that Rome officials personally tested FSD Supervised bodes well for the program’s approval, as it suggests that key individuals are closely watching Tesla’s efforts and innovations.
Assessor Patanè also highlighted the administration’s interest in technologies that boost road safety and urban travel quality, viewing them as aids for both private and public transport while respecting rules.
Replies on X urged involving Italy’s Transport Ministry to speed approvals, with one user noting, “Great idea to involve the mayor! It would be necessary to involve components of the Ministry of Transport and the government as soon as possible: it’s they who can accelerate the approval of FSD in Italy.”

Tesla FSD (Supervised) blows away French journalist after test ride
Cadot described FSD as “mind-blowing,” both for the safety of the vehicle’s driving and the “humanity” of its driving behaviors.
Tesla’s Full Self-Driving (Supervised) seems to be making waves in Europe, with French tech journalist Julien Cadot recently sharing a positive first-hand experience from a supervised test drive in France.
Cadot, who tested the system for Numerama after eight years of anticipation since early Autopilot trials, described FSD as “mind-blowing,” both for the safety of the vehicle’s driving and the “humanity” of its driving behaviors.
Julien Cadot’s FSD test in France
Cadot announced his upcoming test on X, writing in French: “I’m going to test Tesla’s FSD for Numerama in France. 8 years I’ve been waiting to relive the sensations of our very first contact with the unbridled Autopilot of the 2016s.” He followed up shortly after with an initial reaction, writing: “I don’t want to spoil too much because as media we were allowed to film everything and I have a huge video coming… But: it’s mind-blowing! Both for safety and for the ‘humanity’ of the choices.”
His later posts detailed FSD’s specific maneuvers that he found particularly compelling. These include the vehicle safely overtaking a delivery truck by inches, something Cadot said he personally would avoid to protect his rims, but FSD handled flawlessly. He also praised FSD’s cyclist overtakes, as the system always maintained the required 1.5-meter distance by encroaching on the opposite lane when clear. Ultimately, Cadot noted FSD’s decision-making prioritized safety and advancement, which is pretty remarkable.
FSD’s ‘human’ edge over Autopilot
When asked if FSD felt light-years ahead of standard Autopilot, Cadot replied: “It’s incomparable, it’s not the same language.” He elaborated on scenarios like bypassing a parked delivery truck across a solid white line, where FSD assessed safety and proceeded just as a human driver might, rather than halting indefinitely. This “humanity” impressed Cadot the most, as it allowed FSD to fluidly navigate real-world chaos like urban Paris traffic.
Tesla is currently hard at work pushing for the rollout of FSD to several European countries. Recent reports have revealed that Tesla has received approval to operate 19 FSD test vehicles on Spain’s roads, though this number could increase as the program develops. As per the Dirección General de Tráfico (DGT), Tesla would be able to operate its FSD fleet on any national route across Spain. Recent job openings also hint at Tesla starting FSD tests in Austria. Apart from this, the company is also holding FSD demonstrations in Germany, France, and Italy.

Tesla Optimus shows off its newest capability as progress accelerates
Tesla Optimus showed off its newest capability as progress on the project continues to accelerate toward an ultimate goal of mass production in the coming years.
Tesla is still developing Optimus and preparing for the first stages of mass production, where units would be sold and shipped to customers. CEO Elon Musk has always marketed the humanoid robot as the biggest product in history, even outside of Tesla, but of all time.
He believes it will eliminate the need to manually perform monotonous tasks, like cleaning, mowing the lawn, and folding laundry.
However, lately, Musk has revealed even bigger plans for Optimus, including the ability to relieve humans of work entirely within the next 20 years.

Optimus has also made several public appearances lately, including one at the Neural Information Processing Systems, or NeurIPS Conference. Some spectators shared videos of Optimus’s charging rig, as well as its movements and capabilities, most interestingly, the hand:

The hand, forearm, and fingers have been one of the most evident challenges for Tesla in recent times, especially as it continues to work on its 3rd Generation iteration of Optimus.
Musk said during the Q3 Earnings Call:
“I don’t want to downplay the difficulty, but it’s an incredibly difficult thing, especially to create a hand that is as dexterous and capable as the human hand, which is incredible. The human hand is an incredible thing. The more you study the human hand, the more incredible you realize it is, and why you need four fingers and a thumb, why the fingers have certain degrees of freedom, why the various muscles are of different strengths, and fingers are of different lengths. It turns out that those are all there for a reason.”
The interesting part of the Optimus program so far is the fact that Tesla has made a lot of progress with other portions of the project, like movement, for example, which appears to have come a long way.
However, without a functional hand and fingers, Optimus could be rendered relatively useless, so it is evident that it has to figure this crucial part out first.
