SpaceX Falcon Heavy to launch NASA ocean moon explorer, saving the US billions
In a move that’s likely to save the US taxpayer several billion dollars over the next few years, NASA has carefully extricated a mission to one of Jupiter’s ocean moons from the claws of its own Space Launch System (SLS) rocket.
Known as Europa Clipper, the six metric ton (~13,300 lb) spacecraft will instead launch on a SpaceX Falcon Heavy rocket for less than $180M. Had Falcon Heavy not been ready or NASA shied away from the challenge of switching launch vehicles, sending the ~$4.25 billion orbiter to Jupiter could have easily added more than $3 billion to the mission’s total cost. Instead, Europa Clipper will be able to launch one or two years earlier than SLS would have been ready and at a cost that’s practically a rounding error relative to the alternative.
Measuring approximately 3100 km (~1940 mi) in diameter, Europa is approximately 10% smaller and 30% less massive than Earth’s Moon. Both are similar balls of rock with solid metallic cores. However, based on observations taken over decades by spacecraft and Earth-based telescopes, odds are good that Europa also has a vast liquid water ocean insulated by 10-30 km (6-20 mi) of ice so cold that it’s as hard as granite.
Scientists estimate that Europa’s saltwater ocean is dozens to 100+ km (~62 mi) deep, covers the moon’s entire surface, and holds more water than all of Earth’s oceans combined. Signs of a liquid ocean under Europa’s crust (and the crust of numerous other outer solar system moons, as it would turn out) were especially surprising because of the implication that those moons possessed vast heat sources. In the case of Europa, it’s believed that Jupiter’s immense gravitational pull and the moon’s close orbit are balanced in such a way that Europa is heated as those tidal forces violently stretch and squeeze its interior.
In an orbit 30% lower than Europa, tidal heating is so aggressive that the moon Io is littered with titanic volcanoes and lava lakes more than 200 km (~120 mi) across – so large that waves have been spotted on its surface with Earth-based telescopes. In short, because Europa appears to be in the right place to have enough – but not too much – tidal heating, it’s believed to be one of the best potential harbors of extraterrestrial life and Europa Clipper’s primary purpose is to pursue that potential astrobiological treasure trove.
Europa Clipper’s history is a truly bizarre one. Championed almost singlehandedly by fundamentalist Christian and former Republican Representative John Culberson, it’s almost certain that the mission would have never come together and never secured enough funding to proceed. Culberson’s singular goal: determine if humanity is (or is not) alone in the universe. If life can independently evolve twice in the same average solar system, the logic goes, it would practically guarantee that life will be omnipresent anywhere we look.
Culberson’s original vision was an orbiter (Clipper) that would effectively scout Europa for a lander that would follow just a few years later. Incredibly, he appears to have all but guaranteed that Europa Clipper will launch. However, he lost a reelection bid in 2018, casting the lander component into limbo before proper funding or commitments could be ascertained. It now seems likely that the future of Europa Lander will depend almost entirely on what Clipper does (or doesn’t) find.
Europa Clipper is now scheduled to launch on an expendable Falcon Heavy rocket no earlier than a two-week window set to open in October 2024. As part of the politicking to secure the billions of dollars needed to fund the mission, Culberson originally shackled Europa Clipper to NASA’s SLS rocket – now half a decade behind schedule and set to cost more than $23 billion before its first launch. However, it appears that SLS is so mismanaged and uncharacterized that even its infamously zealous, pork-motivated Congressional cheerleaders weren’t willing to put up a public fight to retain the SLS rocket’s only confirmed non-human payload.
Ultimately, on launch alone, Falcon Heavy’s Europa Clipper launch will likely save taxpayers more than $2 billion – the likely minimum cost of a single SLS Cargo launch. Due to issues with the rocket, Ars Technica also reports that Europa Clipper and SLS would have required at least $1 billion in modifications and upgrades to safely fly, meaning that choosing SpaceX will likely end up saving NASA more than $3 billion – equivalent to almost three-quarters of the entire Europa Clipper mission’s price tag.

SpaceX set to launch astronauts and a classified Falcon Heavy mission on the same day
SpaceX plans three launches Thursday, including Crew-13 astronauts and Falcon Heavy’s first classified NRO mission.
SpaceX is lining up one of the busiest single days in its history, and the company offered a preview on Wednesday morning with a simple post on X: “Sunrise at pad 40.” The video and photos show Falcon 9 standing at Space Launch Complex 40 at Cape Canaveral, roughly a day before it is scheduled to carry four astronauts to the International Space Station.
That launch is only the first of three SpaceX missions planned for Thursday, October 1, across both coasts.

Crew-13 is targeting liftoff at 11:10 a.m. ET, with a backup opportunity Friday at 10:47 a.m. ET. NASA astronaut Jessica Watkins will command the mission, with NASA’s Luke Delaney as pilot and Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov serving as mission specialists. According to NASA, Dragon is set to dock with the forward port of the station’s Harmony module around 8 p.m. ET, less than nine hours after launch. Watkins is the only member of the crew who has flown before, and Kutryk will become the first Canadian to reach orbit through NASA’s Commercial Crew Program.
The Falcon 9 booster is flying for the third time after supporting Crew-12 and a Starlink mission, and it will attempt a landing at Landing Zone 40 beside the pad. That site made its debut in February when the Crew-12 booster touched down there, as Teslarati reported at the time. Crew-13 will relieve the Crew-12 astronauts, who have been aboard the station since the middle of February.
On the West Coast, another Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in a window running from 2:18 to 3:16 p.m. ET, a flight NASASpaceflight lists as a Transporter rideshare mission.
The day is set to close at 11:53 p.m. ET, when Falcon Heavy launches from Launch Complex 39A with NROL-97, the first National Reconnaissance Office payload ever to fly on the rocket. SpaceX rolled the vehicle out to the pad Tuesday night. Its two side boosters, which previously flew GOES-U, ViaSat-3 F3 and NASA’s Roman Space Telescope, will return to Landing Zones 1 and 2, while a new center core will be expended in the Atlantic. The Roman launch took place on August 30, so NROL-97 will come barely a month later as Falcon Heavy’s third flight of 2026 and 14th overall.
NASA taps SpaceX to launch the telescope that could unlock new worlds
If all three Florida boosters land as planned, it would be the first time the Space Coast has seen landings at LZ-40, LZ-1 and LZ-2 on the same day, according to the Orlando Sentinel, which has warned residents in Brevard, Orange and Volusia counties that more than one sonic boom is possible.
The schedule arrives just three days after Starship reached orbit for the first time on Flight 14 from Starbase, Texas, deploying 26 Starlink V3 satellites. If Thursday’s missions stay on time, SpaceX will have flown Starship, Falcon 9 and Falcon Heavy from four different pads in about four days.
Crew-13 is also the start of a longer run for Dragon. NASA recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification, keeping Dragon as the agency’s only operational ride to the station while Boeing’s Starliner remains grounded.
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
