SpaceX’s Falcon Heavy eyed by Europe/Japan as ULA nails spectacular Delta Heavy launch
According to RussianSpaceWeb, SpaceX’s Falcon Heavy rocket is under serious consideration for launches of major European and Japanese payloads associated with the Lunar Orbital Platform-Gateway (formerly the Deep Space Gateway).
Currently targeting launch readiness in the mid-2020s, those heavy scientific and exploratory government payloads are eyeing Falcon Heavy at the same time as the United Launch Alliance’s (ULA) Delta IV Heavy – the most powerful operational rocket prior to FH’s debut – is busy wrapping up a scientific launch for NASA and prepping for another launch in September for its singular anchor customer, the National Reconnaissance Office (NRO).

A breathtaking mission to the sun
United Launch Alliance (ULA) has just completed the ninth successful launch of its Delta IV Heavy rocket, originally developed by Boeing in the 1990s and debuted in 2004 before the company’s launch vehicle subsidiary joined forces with Lockheed Martin’s own rocket branch. Delta Heavy’s August 12th mission saw the rocket send a small NASA payload known as Parker Solar Probe (PSP) on a trajectory that will eventually place the craft closer to the Sun than any human-made object before it. In pursuit of a better understanding of how exactly our solar system’s namesake functions and behaves, PSP will also become the fastest object ever created by humans, traveling at an extraordinary 200 km/s (120 mi/s) at the zenith of its deepest periapses (the point at which PSP is closest to the sun).
In a fitting send-off for the small heat-shielded spacecraft, Delta IV Heavy’s launch was a spectacle to behold, with clear skies and the cover of darkness combining to magnify the best of the rocket’s telltale features. Upon ignition of its three massive RS-68 rocket engines, each producing over 700,000 lb-ft of thrust, the rocket is held down for several seconds in a process that famously culminates in what appears to be self-immolation just before liftoff, a consequence of the rocket burning off excess hydrogen fuel expelled during the ignition process. Unlike Falcon 9’s dirtier kerosene-oxygen combustion, Delta Heavy’s hydrogen and oxygen fuel produce a flame that is nearly transparent, aside from a bright orange tint created by materials in each engine’s ablative (read: designed to disintegrate) nozzle.

While Delta IV Heavy has used one of its other nine successful launches for a NASA payload (a test flight of the Orion capsule), all seven remaining missions were conducted for the USAF (1) and the National Reconnaissance Office (NRO; 6), and all six remaining missions on the rocket’s manifest also happen to be for the NRO. Put simply, Delta IV Heavy would not exist today if the NRO did not have an explicit and unflappable need for the capabilities it offers. The primary downside is cost: DIVH costs at least $350 million and usually more than $400m per launch. Thankfully for ULA, the NRO has very few problems with money, and the agency’s estimated annual budget of $10 billion (2013) is more than half of NASA’s entire budget.
After Falcon Heavy’s successful debut, Delta IV Heavy’s monopoly over heavyweight NRO and USAF payloads is rapidly coming to an end, and both agencies are almost certainly attempting to equally quickly certify SpaceX’s newest rocket for critical national security space (NSS) launches. With that influx of the slightest hint of competition, Delta IV Heavy’s ~$400 million price tag starts to look rather painful in comparison to Falcon Heavy’s cost ceiling of around $150 million, potentially much less in the event that 1-3 of its boosters are recoverable. That competition likely won’t kill Delta IV Heavy, thanks entirely to the anchor support of the NRO, but it most certainly will guarantee that Delta Heavy is retired the moment ULA’s next-gen Vulcan rocket is ready to take over, likely no earlier than 2024.

Outside of the NRO, however, there is a surprising amount of interest in Falcon Heavy for interesting (and heavy) government payloads, particularly with respect to the NASA/ESA/JAXA/Roscosmos cooperative lunar space station, known as the Lunar Orbital Platform-Gateway.
Falcon Heavy enters the mix
The first payload considering Falcon Heavy for launch services is the Japanese Space Agency’s (JAXA) HTV-X, and upgraded version of a spacecraft the country developed to assist in resupplying the International Space Station (ISS). HTV-X is primarily being designed with an ISS-resupply role still at the forefront, but Russianspaceweb recently reported that JAXA is seriously considering the development of a variant of the robotic spacecraft dedicated to resupplying the Lunar Orbital Platform-Gateway (LOPG; and I truly wish I were joking about both the name and acronym).

As the name suggests, LOPG is fundamentally a shrunken, upgraded copy of the present-day International Space Station but with its low Earth orbit swapped for an orbit around the Moon. Why, you might ask? It happens that that question is far less sorted at this point than “how”, and there’s a fairly strong argument to be made that NASA is simply attempting to create a low-hanging-fruit destination for the chronically delayed SLS rocket and Orion spacecraft it routinely spends ~20% of its annual budget on. The alternatives to such a crewed orbital outpost are actually landing on the Moon and building a base or dramatically ramping development of foundations needed to enable the first human missions to Mars.

Regardless of the LOPG’s existential merits, a lot of energy (and money) is currently being funneled into planning and initial hardware development for the lunar station’s various modular segments. JAXA is currently analyzing ways to resupply LOPG and its crew complement with its HTV-X cargo spacecraft, currently targeting its first annual ISS resupply mission by the end of 2021. While JAXA will use its own domestic H-III rocket to launch HTV-X to the ISS, that rocket simply is not powerful enough to place a minimum of ~10,000 kg (22,000 lb) on a trans-lunar insertion (TLI) trajectory. As such, JAXA is examining SpaceX’s Falcon Heavy as a prime (and affordable) option: by recovering both side boosters on SpaceX’s drone ships and sacrificing the rocket’s center core, a 2/3rds-reusable Falcon Heavy should be able to send as much as 20,000 kg to TLI (lunar orbit), according to comments made by CEO Elon Musk.

That impressive performance would also be needed for another LOPG payload, this time for ESA’s 5-6 ton European System Providing Refueling Infrastructure and Telecommunications (ESPRIT) lunar station module. That component is unlikely to reach launch readiness before 2024, but ESA is already considering Falcon Heavy (over its own Ariane 6 rocket) in order to save some of the module’s propellant. Weighing 6 metric tons at most, Falcon Heavy could most likely launch ESPRIT while still recovering all three of its booster stages.
Regardless of the outcomes of those rather far-off launch contracts, it’s clear that some sort of market exists for Falcon Heavy and even more clear that its injection of competition into the stagnant and cornered heavy-lift launch segment is being globally welcomed with open arms.

Verizon, AT&T and T-Mobile are trying to shut Starlink out before FCC vote
AT&T, Verizon and T-Mobile want 290 MHz cut from an FCC satellite plan before Thursday.
AT&T, Verizon and T-Mobile are asking the Federal Communications Commission to pull nearly 300 MHz of spectrum out of a proposal that would let satellite companies like SpaceX offer cell service directly to ordinary phones. The request lands one day before the agency votes on it.
The FCC will vote Thursday, October 29, on a notice of proposed rulemaking that would make an additional 482 MHz available for direct to device service, expanding the number of eligible bands from five to 13, according to the FCC fact sheet. It would also scrap the rule requiring a satellite operator to lease spectrum from carriers, replacing it with a certification that the operator has coexistence agreements in place or holds the terrestrial license itself.
That second path matters for SpaceX. As Teslarati reported earlier this month, SpaceX agreed to buy Grain Management’s nationwide 800 MHz portfolio to turn Starlink Mobile into a full US carrier, adding to the spectrum it already bought from EchoStar.
The carriers want two bands removed, 2.5 GHz and 3.45 GHz, which make up 290 MHz of the 482 MHz on the table. Through industry group CTIA, they argued that about 300 million users depend on those bands and that satellite operations in them are not technically feasible. T-Mobile, which calls 2.5 GHz the foundation of its Ultra Capacity 5G network, said in its own filing that satellite interference could wipe out up to 96% of a cell site’s uplink coverage area and cut uplink speeds by 88% to 99%.
Executives from all three carriers met with FCC staff on October 20, and T-Mobile CEO Srini Gopalan met separately with FCC Chairman Brendan Carr. T-Mobile’s role stands out because it is still SpaceX’s US launch partner for Starlink Mobile. The three carriers have also teamed up on their own satellite joint venture to pool spectrum, a move widely seen as a response to Starlink.
SpaceX is asking for the opposite. In an October 23 filing after meetings with FCC staff and commissioners’ offices, the company asked regulators to add the 902 to 928 MHz band to the proposal. “Doing so now saves time later,” SpaceX wrote. The company also asked the FCC to modernize interference rules and align satellite deployment requirements with those for terrestrial cell networks, saying the goal is to let satellite and ground networks work together so Americans stay connected wherever they are.
The carriers have not been shy about how they view SpaceX as a competitor. On Verizon’s third quarter earnings call Monday, its chief executive said Starlink Mobile “just can’t compete with a terrestrial network” and estimated SpaceX would need four to six years and $300 billion to $500 billion to build a full US carrier network.
Thursday’s vote will not settle which bands survive. Adopting the notice opens a public comment period, with final rules to come later in the proceeding. The FCC already considered and rejected 2.5 GHz for satellite coverage once, in 2024. SpaceX also is not the only satellite player watching: the FCC approved Amazon’s $11.6 billion acquisition of Globalstar on October 27, giving its planned direct to device fleet its own mobile satellite spectrum.

Starlink is ‘biggest competitive advantage,’ but it’s temporary, United CEO says
United Airlines CEO Scott Kirby said that SpaceX’s Starlink satellite internet is its leading competitive advantage in the U.S. airline industry. However, in recent comments, while he described the service as “the biggest competitive advantage” the carrier currently holds, he also acknowledged that the edge is temporary.
“…everybody eventually is going to have high-speed low earth orbit internet connectivity. It’s going to be a must-have. We are going to have a few years of being the only airline that has it at scale, and that’s our mission,” Kirby said. Until everyone has it, United aims to capitalize on its head start by converting trial users into long-term loyal customers.
🚨 United CEO Scott Kirby calls Starlink “the biggest competitive advantage,” but says it’s temporary.
“I think it’s the biggest competitive advantage. And it’s temporary. Like it’s not, everybody eventually is going to have high speed low earth orbit internet connectivity. It’s going to be a must-have. But we are going to have a few years of being the only airline that has it at scale, and that’s our mission.”
“I think we’re going to convince customers that United is the best airline and we’re going to get customers to switch their loyalty, to get our credit card, switch their loyalty to United. Not because of Starlink. They’re going to try us for Starlink and they’re going to stay with all the other technology, and everything else is better, and the technology in particular is so much better than technology other, and it’s accelerating because we’ve got the right tech stack, and because we’re like, our gap is getting wider and wider with our technology every day.”

United has moved faster than its rivals on Starlink installations. As of mid-to-late October 2026, the system was on roughly 43 percent of its fleet, with plans to reach 61 percent by year-end, 87 percent by June 2027, and full fleet coverage by the end of next year.
The airline already operates more Starlink-equipped flights than the rest of the U.S. industry combined. Los Angeles International Airport is scheduled to become United’s first 100 percent Starlink hub in the first half of 2027, and the carrier’s app will display the likelihood that any given flight has the service.
Kirby has pointed to early evidence that the offering influences booking decisions. Some passengers loyal to other airlines are already switching flights for Starlink connectivity, something the airline, along with American Airlines, has tried to leverage against competing airlines. Both companies used status-match programs, and some of those customers are pursuing company-specific credit cards, which signals an intent to stay.
Once onboard, these customers encounter the airline’s broader investments in aircraft, larger seat-back screens, oversized bins, connection tools, and a mobile app that Kirby says outperforms competitors. Wi-Fi satisfaction scores on Starlink-equipped planes have been reported to be nearly double those on aircraft with other systems.
Competitors are moving slowly to do the same. Southwest Airlines began installations in 2025 and expects to complete them soon. Delta is pursuing Amazon’s Leo system, while American expects to start Starlink work in early 2027 and has not yet detailed regional-fleet plans. This timeline gap gives United a multi-year window in which it remains the only major U.S. carrier offering Starlink at scale.
Kirby has framed the strategy as pressing that advantage while simultaneously widening gaps in other technology areas so that customers who try United for the Wi-Fi remain for the overall experience.
The approach reflects a calculated bet that superior in-flight connectivity can accelerate share gains and support longer-term financial targets, including a 10 percent pre-tax margin goal.
High-speed internet is particularly valued by premium and business travelers who can work or stream reliably. As low-Earth-orbit service becomes ubiquitous, the temporary nature of the pure connectivity edge means United’s retention will depend on whether its other product and operational improvements keep pace.

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady
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
— TESLARATI (@Teslarati) October 26, 2026
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.
