SpaceX’s NASA astronaut launch debut jumps its place in line, now up next
According to NASASpaceflight.com reporter Michael Baylor, SpaceX’s Starlink-7 satellite launch has been indefinitely delayed due to drone ship constraints, meaning that the company’s Crew Dragon astronaut launch is now up next.
As a result, SpaceX’s next orbital launch has been delayed by at least eight days. In return, however, that launch will arguably be the most important in the company’s 18-year history, (hopefully) marking the biggest step by far SpaceX has taken towards its main goals of democratizing spaceflight and enabling the sustainable, permanent settlement of Mars. Known as Demonstration Mission 2 (Demo-2), it will simultaneously be the first crewed launch under NASA’s Commercial Crew Program (CCP) and SpaceX’s first astronaut launch ever and is scheduled to lift off no earlier than (NET) 4:33 pm EDT (20:33 UTC), May 27th.
Formerly scheduled to launch no earlier than (NET) May 7th, 17th, 18th, and 19th after a number of technical and weather-related delays, SpaceX’s 8th 60-satellite Starlink launch has now been delayed until sometime after Crew Dragon’s late-May inaugural astronaut launch. According to NASASpaceflight and speculated about in-depth on unofficial forums in the days prior, the schedule swap decision was made due to constraints in SpaceX’s drone ship. While simple on the face of things, the change does reveal a bit of the hidden strategy behind SpaceX’s management of both its rocket fleet and the ships that recover them.
Compounded by multiple largely unrelated delays, including weather in the planned booster and fairing landing zones, the Starlink-7/Demo-2 launch swap was caused by the simple fact that SpaceX only has one operational drone ship on the East Coast. The company coincidentally began sea trials with a second drone ship the very same day that Of Course I Still Love You (OCISLY) headed out to sea to catch Starlink-7’s Falcon 9 booster. However, that second ship has been extensively upgraded and will likely take several weeks of sea trials before it can be declared ready for its first East Coast rocket recovery attempt.
For each drone ship booster landing, it takes at least a week for the ship to be towed several hundred miles downrange to the recovery zone and at least as long to return to port. Add in the time required to safe and secure a landed Falcon 9 or Heavy booster, navigate sea states to prevent damage to – or the outright loss of – that booster, and the work needed to safely lift it off the drone ship’s deck onto dry land and it can easily be 9-10 days before a drone ship is ready for another landing.
At the same time, SpaceX’s turnaround record is about eight days between booster landings. Had SpaceX persevered and attempted to launch Starlink-7 on May 19th and Crew Dragon’s inaugural astronaut launch on May 27th, it’s possible that things would have worked out, with both booster landings occurring on schedule on the same drone ship. However, given just how much of a priority Crew Dragon Demo-2 is compared to an internal Starlink launch and a tropical storm threatening to delay Starlink-7’s launch and landing even further, SpaceX clearly decided that it just wasn’t worth the risk.
Given the extraordinary importance of Demo-2, set to be the first time the United States has launched its own astronauts into orbit in almost nine years, it’s not exactly surprising that SpaceX has chosen conservatism this time around and prioritized its inaugural NASA astronaut launch. According to Spaceflight Now, the Crew Dragon capsule assigned to SpaceX’s inaugural NASA astronaut launch – pictured above – actually joined the new Falcon 9 rocket that will launch it at Pad 39A on May 15th. Now fully fueled with liquid hydrazine and nitrogen tetroxide, the spacecraft could be mated with Falcon 9’s upper stage at any moment (if it hasn’t been already).
Once fully assembled, Falcon 9 booster B1058, a new Falcon 9 upper stage, Crew Dragon capsule C206, and an expendable trunk section will be rolled horizontally out to Kennedy Space Center (KSC) Pad 39A to perform a crucial pre-launch static fire test. Rollout and static fire operations could begin at any point within the next few days. It remains to be seen whether drone ship OCISLY will remain in the Atlantic Ocean or head back to Port Canaveral before departing again to catch booster B1058.
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:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

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 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 has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
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.
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 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.

It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u

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.
