SpaceX awarded three more NASA astronaut launch contracts

Published

on

Three months after announcing its intent, NASA has procured three more Crew Dragon astronaut launches from SpaceX, raising the total number of operational missions the company is contracted to perform from six to nine.

NASA announced its plans to award additional contracts in December 2021 after releasing a half-hearted Request For Information (RFI) in October. That RFI, which seemingly lacked any real NASA support for an attempt to develop one or more additional crew transport vehicles, unsurprisingly produced the conclusion that the space agency should buy more flights from its existing providers.

Short of a second Commercial Crew Program (CCP), Boeing and SpaceX were thus the only options. Boeing, whose Starliner spacecraft has yet to successfully complete even an uncrewed test flight and remains years behind schedule, was apparently ruled out of this contract add-on. SpaceX, on the other hand, aced uncrewed and crewed Crew Dragon test flights in March 2019 and May 2020 and ultimately began operational astronaut transport missions in November 2020, making it the only logical option.

As such, NASA announced that it would award three more transport contracts to SpaceX, raising the total value of its Commercial Crew Transportation Capability (CCtCap) contract from about $2.6 billion to $3.49B. As of August 2019, NASA’s Office of the Inspector General (OIG) reported that of the original $2.6 billion SpaceX was awarded, the company planned to spend $1.2 billion on development and test flights and $1.4 billion on up to six operational Crew Dragon missions.

At the time, that meant that NASA intended to pay a total of ~$230 million for each of the first six Crew Dragon transport missions, each of which would carry four astronauts to and from the International Space Station and serve as a lifeboat in the six months between launch and landing. For NASA’s contract modification, the space agency will now pay the company no more than $890 million – up to $297 million apiece – for three more transport missions, each likely carrying four astronauts.

For missions seven through nine, NASA will thus pay an average of up to ~$74 million per seat – substantially more expensive than the ~$55 million per seat SpaceX’s first six Crew Dragon missions will cost the space agency. To be clear, there’s a chance that a significant fraction of the $890 million contract value increase actually came before the addition of three more missions, in which case NASA might instead be paying around $700-800 million or around $60-70M per seat for three more Dragon launches. Regardless, that’s cheaper than the ~$90 million per seat Boeing’s Starliner is expected to cost. At the end of NASA’s Soyuz ridesharing efforts, the agency was also being gouged for about ~$90 million per seat to launch its astronauts on Russian Soyuz missions.

Update: There is evidence that SpaceX’s total CCtCap contract value was about $2.74 billion before the addition of three more missions, meaning that NASA is likely paying SpaceX around $755 million or ~$63 million per seat – a more reasonable 15% increase over earlier pricing.

SpaceX remains on track to launch Crew-4 no earlier than (NET) 15 April 2022, Crew-5 NET October 2022, and Crew-6 NET February 2023. The company is now expected to complete all six of its first operational crew transport missions before Boeing’s Starliner spacecraft completes a single one. In fact, it’s increasingly plausible that SpaceX will launch all six of its original Crew missions before Starliner attempts its first crewed test flight – a milestone Crew Dragon passed in May 2020.

It remains to be seen when Starliner will finally become operational. If Boeing manages that feat by mid-2023, there’s at least a chance that Starliner and Crew Dragon will finally be able to start alternating launches, in which case NASA’s three extra Dragon launches might last until 2027. Starliner would then have three more missions remaining, allowing NASA to stretch its 15 existing Commercial Crew transport contracts as far as H2 2028.

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

Published

on

Credit: SpaceX

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.
