SpaceX waits in the wings as NASA risks maiming Jupiter probe to pinch pennies
SpaceX and its Falcon Heavy rocket continue to wait in the wings as NASA risks maiming its ‘Europa Clipper’ Jupiter probe by pinching the wrong pennies.
For the second time, NASA has performed “continuation/termination reviews” of three of the Europa Clipper spacecraft’s scientific instruments after budget overruns on the order of no more than a few tens of millions of dollars. Thankfully, no instruments were canceled, unlike the “ICEMAG” magnetometer that was functionally killed last year. Still, a NASA program scientist casually noted that the space agency would tolerate launching without one of two cameras and would offer no more funding to a mass spectrometer instrument (MASPEX), raising the risk of instrument failure during the challenging mission.
For any scientific spacecraft or rover, the instruments carried along are effectively the entire reason for their existence: if those instruments are faulty (or even removed before launch), the mission is effectively rendered pointless. Further, due to the sheer complexity and challenges posed by the act of getting to the destination and surviving after arrival, the actual instruments most scientific spacecraft carry represent a tiny fraction of the overall mission cost and mass. It’s not easy to readily imagine a better way to signal inept program management than by singularly focusing on that tiny, lifeblood-esque portion of a spacecraft’s budget. Undeterred, that is exactly what NASA appears to be doing with Europa Clipper – penny-wise, perhaps, but undoubtedly pound-foolish.

It’s not always true that only a small portion of an exploratory spacecraft’s budget is spent on scientific instruments but it absolutely is when it comes to Europa Clipper. Originally hoped to cost as little as $2 billion in 2013, Europa Clipper’s budget allocation has ballooned to $4.5 billion over the life of the program. Of that $4.5 billion, as little as $110M was dedicated to nine scientific instruments assigned to the spacecraft – a ratio of ~41:1. Even if instrument cost ballooned by 100% to ~$220 million, it would still be a measly 20:1. The space environment around Jupiter is admittedly one of the most challenging in the Solar System, warranting some imbalance, but either ratio is still exceptionally bad as far as most exploratory missions go.
Designed to create detailed maps of Europa’s theorized water oceans, ICEMAG, for example, jumped from a $30 million cost estimate to $45 million before NASA abruptly killed it. A Clipper planetary scientist called ICEMAG “a critical instrument that’s been central to Europa science forever”. MASPEX, meanwhile, is a mass spectrometer that will be used to analyze possible chemicals captured by flying through Europa’s transient atmosphere (or, even better yet, plumes from vast ocean geysers). In other words, the instrument most likely to be hobbled next by NASA is also the only instrument on Europa Clipper capable of potentially detecting signs of life by directly sampling material ejected by Europa’s plumes.
Even just with ICEMAG removed, the value proposition of a $4.5 billion mission to an ocean moon of Jupiter becomes much hazier. With ICEMAG removed and MASPEX at risk of being thrown to the wolves, Europa Clipper’s purpose becomes even weaker. Of course, seven valuable instruments remain – some of which partially overlap with MASPEX’ goals – and MASPEX could still technically make it to the finish line in its original handicap-free state, but the tides are definitely not moving in an encouraging direction.


The worst part is that excluding the extraordinarily expensive spacecraft that will host instruments worth ~3-5% its cost, Congress has been dead-set on forcing Europa Clipper to launch on NASA’s chronically-delayed, over-budget Space Launch System (SLS) rocket. SLS has yet to launch once despite more than a decade of development and almost $30 billion spent on the rocket alone, and it would take a miracle for an SLS rocket to be ready to launch Clipper before 2025 or 2026. Europa Clipper is working towards a launch no earlier than 2024, meaning that the spacecraft would have to be stored indefinitely at a cost of at least $125 million per year.
Intrepid readers may note that the cost of simply waiting a single year for SLS to be ready for launch is higher than the cost of all of Europa Clipper’s scientific instruments at their original $110 million budget. The actual cost to NASA for a single SLS launch is expected to $1.5 billion at the absolute minimum, while $2-2.5 billion is far more reasonable. With a little effort and some moderate cruise stage tweaks, Ars Technica has already reported that an expendable SpaceX Falcon Heavy rocket augmented with an off-the-shelf kick stage could send Europa Clipper to Jupiter in 5-6 years, compared to ~3 with SLS.


Ironically, that means that if Falcon Heavy was ready to launch Europa Clipper when the spacecraft is expected to be ready in 2024, it would actually arrive at the same time (or close) if it launched on SLS – once a minimum two-year launch vehicle delay is accounted for. A Falcon Heavy would also save NASA at least $1-2 billion, while it would directly save the Europa Clipper program the ~$250 million it would otherwise need to spend to store the spacecraft while waiting years for an SLS rocket. That $250 million alone – an inevitable add-on cost if SLS is chosen – could easily double the budget of every single Europa Clipper science instrument, adding plenty of breathing room, reinstating ICEMAG, and likely improving the science they output – data-gathering quite literally being the whole purpose of the mission.
Of course, the odds that NASA actually steps out from under the political shadow of SLS and stops playing penny wise and pound foolish with the extraordinarily expensive science missions it shepherds is unlikely. But still, the possibility (and hope) remains. Most recently, a very slight change in the wording of a proposed law (bill) could give the Europa Clipper program the legal wiggle room it needs to sidestep Congress’ desire to force it to launch on SLS. Of course, the senators and representatives with parochial attachment to the rocket will continue to fight tooth and nail to legally force it upon NASA at every possible turn, but there is now at least a chance of a sane outcome.

Tesla Cybertruck production snaps back after ugly supplier fight
Cybertrucks are piling up again at Giga Texas after Tesla’s court win against a parts supplier.
Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.
Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.
Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.
TESLA: U.S. District Judge Christopher R. Wolfe of the U.S. District Court for the Western District of Texas, Waco Division granted Tesla a Temporary Restraining Order and Writ of Replevin in its dispute with Angstrom Automotive (Case No. 6:26-cv-00477).

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.
Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.

Space finally faced the people living next to its next Terafab mega-project
SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.
SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.
The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.
Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.
SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.
SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.
Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.

SpaceX has solved Starship’s biggest challenge, Elon Musk says
Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.
During the company’s first-ever Earnings Call, the SpaceX CEO stated:
“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”
Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.
Elon says he believes the heat shield problem with Starship is currently solved.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.
The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.
These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.
Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.
Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.
Elon Musk sheds two new bits of detail on Starship after 13th test launch
Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.
Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.
