SpaceX installs Dragon spaceship on the rocket that’ll take it to space (again)

Published

on

For the third time ever, SpaceX has installed a Crew Dragon spacecraft scheduled to launch astronauts on the Falcon 9 rocket that’ll carry it to orbit, sailing past one of the mission’s last major preflight milestones.

Known as Crew-2, the NASA Commercial Crew Program (CCP) mission will be SpaceX’s second operational crew ferry mission after its operational Crew-1 debut launched flawlessly on November 15th, 2020. Since November 16th, the Crew-1 Crew Dragon has been docked to the International Space Station (ISS) in Low Earth Orbit (LEO) – marking at least two major firsts – and won’t return to Earth until Crew-2 has safely joined it at the station.

Simultaneously developed as part of the Commercial Crew Program, a raft of technical and organizational shortcomings have extensively delayed Boeing’s Starliner crew capsule, effectively forcing NASA to lean on SpaceX to pick up the slack with multiple back-to-back Crew Dragon missions. Organizational excellence aside, Crew-2 is also on track to secure two of the most significant reusability achievements in SpaceX’s long history of significant reusability achievements.

Mere days after a SpaceX Falcon 9 rocket and Crew Dragon spacecraft lifted off with NASA astronauts aboard for the first time ever, becoming the first crewed launch in history to use a commercially-developed rocket or spacecraft, the space agency effectively gave the company permission to fly its astronauts on flight-proven versions of those same vehicles.

While those plans have effectively fallen under the radar relative to other SpaceX activities, it’s not unreasonable to say that a successful Crew-2 launch with both a flight-proven Falcon 9 booster and Crew Dragon capsule would be one of the most significant technical achievements in the company’s history. At the bare minimum, it will be the most symbolically significant achievement in SpaceX’s history.

In essence, success would mean that SpaceX has unequivocally proven that a private company can develop – from scratch – methods of rocket and spacecraft reusability that are so successful and so reliable that perhaps the most risk-averse customer on Earth is willing to place the lives of its astronauts in the hands of those flight-proven spacecraft and rockets. If SpaceX can accomplish that feat with Falcon 9 and Crew Dragon, there is no practical reason to doubt that it can be repeated with Starship – a vehicle that has already piqued NASA’s interest.

The Crew Dragon capsule assigned to Crew-2 debuted on May 30th, 2020 and carried NASA astronauts Bob Behnken and Doug Hurley to the ISS without any major issue, where it spent a little over two months in orbit. On August 2nd, the spacecraft safely reentered Earth’s atmosphere traveling around 7.5 kilometers per second (17,000 mph) and splashed down in the Gulf of Mexico with both astronauts none the worse for wear. Since then, SpaceX has disassembled the Dragon, carefully inspected every possible inch, and refurbished the vehicle for Crew-2.

Despite the historic nature of the task of qualifying and refurbishing the first commercial spacecraft in history that is expected to launch NASA astronauts twice, Crew Dragon C206’s turnaround will be the fastest in Dragon history – and by a margin of almost 40%.

After acing its role in SpaceX’s first operational astronaut launch five months ago, Falcon 9 booster B1061 will also be flying for the second time on Crew-2 – especially fitting given that the Crew-2 will meet the only other spacecraft and astronauts launched on the same booster at the ISS. As of Thursday, April 15th, Crew-2 is seven days away from a launch planned no earlier than 6:11 am EDT (10:11 UTC) on Thursday, April 22nd. The flight-proven Dragon and Falcon 9 booster and a new, expendable upper stage are expected to roll out to Pad 39A within the next few days for an integrated static fire test 4-5 days prior to launch.

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

Published

on

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.

Tesla expands Robotaxi geofence in Houston with an ode to SpaceX merger

Published

on

Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.

Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.

The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.

Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.

Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.

Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.

Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.

Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.

The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.

Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
