Just three weeks ahead of liftoff, NASA and launch provider United Launch Alliance (ULA) announced that NASA’s Mars 2020 rover, Perseverance, and its Martian helicopter sidekick, Ingenuity, were mated with the Atlas V 541 rocket that will kick off the seven-month journey to the Red Planet. The precious cargo encapsulated inside of a protective payload fairing was carefully hoisted by crane operators to rest atop the Atlas V rocket. The payload joins the Atlas V common core booster, four solid rocket boosters, and the Centaur upper stage to achieve the stack’s final flight configuration height of 197 feet (60 meters).

The final stacking procedure was completed inside of the Vertical Integration Facility (VIF) at Cape Canaveral Air Force Station’s Space Launch Complex 41 (SLC-41). The rocket and payload will remain inside the protective structure and complete final check out tests until it is time quite literally roll to the launchpad. Crane operators first set down the payload for a soft touch to begin final full physical and electrical connection. The spacecraft and rocket will undergo integrated electrical testing as well as a battery of other tests as separate spacecraft and simultaneously as one complete unit.

On Friday (July 10), ULA president and chief executive officer, Tory Bruno, stated on Twitter that the Integrated Systems Test (IST) had been completed successfully. According to a previous mission statement posted to the ULA blog site, the IST is a typical pre-launch run down of the various connected systems between the spacecraft and launch vehicle to “verify proper functionality of launch vehicle systems, (and) conduct a simulated countdown and run through the launch sequence.”

The launch vehicle and integrated payload will remain inside the VIF undergoing mission-specific activities and final system checkouts over the next two weeks. Once all pre-flight activities have been successfully completed, approximately two days ahead of the scheduled launch attempt, the entire stack located on top of the Mobile Launch Platform will make the 1,800ft (550 meters) trip to the SLC-41 launchpad which will take about forty-minutes on a modified railway.

Known as an astrobiology mission and outfitted with seven instruments, the Perseverance rover will conduct new science, sample collection, and test new technology in search of ancient microbial life on the distant planet. The rover will spend the length of one Martian year – two Earth years – exploring the region around its landing site. It will collect and cache samples of the Martian surface to possibly be collected and returned to Earth by future joint missions currently under consideration by NASA and the European Space Agency.

The first interplanetary helicopter, Ingenuity, is a small 4-pound (1.8 kilograms) autonomous solar-powered aircraft that will conduct a series of experimental test flights. Ingenuity is traveling to Mars solely for a demonstrative mission and is not connected to the Perseverance rover by any means other than hitching a ride to the Red Planet. The new technology will demonstrate an ability to create lift in the thin atmosphere and lower gravity environment of Mars to help inform future aerial exploration and science delivery missions.

Currently, NASA and ULA are targeting the launch of the interplanetary mission on July 30th at 7:50 am EDT/4:50 PDT. Should they be necessary, multiple backup launch opportunities are available until the close of the interplanetary launch window on August 15th. Regardless of the launch date, after a seven-month-long, 290 million mile (467 million kilometers) journey – the rover and helicopter will arrive at Mars’s Jezero Crater, the home to an ancient Martian river delta, for a landing attempt on February 18, 2021. The landing date is perhaps even more crucial than the launch date as mission planners must take into account landing site lighting and temperature conditions and the locations of Mars-orbiting satellites required to relay crucial mission-specific information back to Earth.

Should the launch have to abort, and the 2020 window is missed completely, the robots will have to wait until 2022 when Earth’s orbit lines up just right with that of Mars, and the next interplanetary launch window opens up.

Tesla has a Cybercab problem nobody saw coming

Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.

Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”

Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.

The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.

Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.

The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.

Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady

Published

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.

Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.

This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.

This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.

Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.

Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.

The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.

Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.

For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.

Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.

Tesla Assisted Driving expands to tenth EU country

Published

on

Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.

Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.

The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.

Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.

In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.

Tesla starts showing how FSD will change lives in Europe

The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.

The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.

These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.

However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
