SpaceX’s upgraded Starship set for test flight despite sore NASA contract losers
Within the last week, while SpaceX has been diligently working to ready an upgraded Starship prototype for its first launch, former competitors Blue Origin and Dynetics – both of which recently lost a historic NASA Moon lander contract to SpaceX – have filed “protests” and forced the space agency to freeze work (and funds).
That means that NASA is now legally unable to use funds or resources related to its Human Lander System (HLS) program or the $2.9 billion contract it awarded SpaceX on April 16th to develop a variant of Starship to return humanity to the Moon. However, just like SpaceX has already spent a great deal of its own time and money on Starship development and – more recently – a rapid-fire series of launches, the company appears to have no intention of letting sore losers hamper its rocket factory or test campaign.
Instead, on the same two days Blue Origin and Dynetics loudly filed official protests with the US Government Accountability Office (GAO), SpaceX performed two back-to-back static fire tests with a Starship prototype and Raptor engines outfitted with “hundreds of improvements.” Technical challenges and unsavory weather conditions forced SpaceX to call off a launch planned sometime last week but the company now appears to be on track to launch Starship prototype SN15 as early as Tuesday, May 4th.
In principle, the ability for companies to protest US government contracting decisions is a necessity and (nominally) a net good but it can easily be misused – and often in damaging ways. In the case of Blue Origin and Dynetics, it’s difficult not to perceive both protests as examples of the latter.
Blue Origin effectively disagrees with every single major point made and conclusion drawn by NASA’s Source Selection Authority (Kathy Lueders) and a separate panel of experts – often to the point that the company is strongly implying that it understands NASA’s contracting process better than the space agency itself. Blue Origin partners Northrop Grumman and Lockheed Martin are both partially or fully responsible for several of their own catastrophic acquisition boondoggles (F-35, Orion, SLS, James Webb Space Telescope, etc.) and are part of the military-industrial complex primarily responsible for turning US military and aerospace procurement into the quagmire of political interests, quasi-monopolies, and loopholes it is today.
The primary argument is generally shared by both protestors. In essence, Dynetics [p. 23; PDF] and Blue Origin [PDF] believe that it was unfair or improper for NASA to select just a single provider from the three companies or groups that competed. They argue that downselecting to one provider in lieu of budget shortfalls changed the procurement process and competition so much that NASA should have effectively called it quits and restarted the entire five-month process. Blue Origin and Dynetics also both imply that they were somehow blindsided by NASA’s concerns about a Congressional funding shortfall.
In reality, NASA could scarcely have been clearer that it was exceptionally sensitive about HLS funding and extremely motivated to attempt to return humans to the Moon by 2024 with or without the full support of Congress – albeit in fewer words. As Lueders herself noted in the HLS Option A award selection statement, the solicitation Blue, Dynetics, and SpaceX responded to states – word for word – that “the overall number of awards will be dependent upon funding availability and evaluation results.”
Additionally, implications that NASA somehow blindsided offerors with its lack of funding are woefully ignorant at best and consciously disingenuous at worse. Anyone with even the slightest awareness of the history of large-scale NASA programs would know that the space agency’s budget is all but exclusively determined by Congress each year and liable to change just as frequently if political winds shift. Short of blackmailing members of Congress or wistfully hoping that other avenues of legal political influence and partnership actually lead to desired funding and priorities appearing in appropriations legislation, NASA knows the future of its budget about as well as anyone else with access to the internet and a rudimentary awareness of history and current events.
It became clear that Congress was likely to drastically underfund NASA’s HLS program as early as November 2020 – weeks before HLS Option A proposals were due. The latest appropriations bill was passed on January 3rd, 2021, providing NASA $850 million of the ~$3.4 billion it requested for HLS. Historically, NASA’s experience with the Commercial Crew Program – public knowledge available to anyone – likely made it clear to the agency that it could not trust Congress to fund its priorities in good faith when half a decade of drastic underfunding ultimately delayed the critical program by several years. That damage was done by merely halving NASA Commercial Crew budget request from 2010 to 2013, whereas Congress had already set itself on a path to provide barely a quarter of the HLS funds NASA asked for in the weeks before Moon lander proposals were due.
Ultimately, the protests filed by Blue Origin and Dynetics are packed to the brim with petty axe-grinding, attempts to paint SpaceX in a negative light, and a general lack of indication that either company is operating in good faith. Instead, their protests appear all but guaranteed to fail while simultaneously forcing NASA to freeze HLS work and delay related disbursements for up to 100 days. Given that SpaceX is now technically working to design, build, qualify, and fly an uncrewed Lunar Starship prototype by 2023 and a crewed demonstration landing by 2024, 100 days represents a full 7-10% of the time that’s available to complete that extraordinary task.
Ironically, the protests made by Blue Origin and Dynetics have already helped demonstrate why NASA’s decision – especially in light of unambiguous budgetary restrictions – to sole-source its HLS Moon lander contract to SpaceX was an astute one. Had a victorious Blue Origin or Dynetics been in a similar position to SpaceX, it’s almost impossible to imagine either team continuing work to a significant degree in lieu of NASA funding or direction. SpaceX, on the other hand, hasn’t missed a beat and looks set to continue Starship development, production, and testing around the clock regardless of NASA’s capacity to help.
In other words, with a little luck, the actual schedule impact of a maximum 100-day work and funding freeze should be a tiny fraction of what it could have been if NASA had selected an HLS provider more interested in profit margins and stock buybacks than creating a sustainable path for humanity’s expansion beyond Earth.
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.
