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 is using a redesigned Cybertruck battery cell to mitigate Semi challenges
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla revealed that it is utilizing redesigned Cybertruck battery cells in its Long Range Semi to mitigate some pertinent challenges that come with long-haul logistics.
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla’s long-awaited Semi truck is entering production at its Nevada Gigafactory, and fresh factory footage reveals a clever evolution in its battery technology.
The Long Range variant, designed for up to 500 miles of real-world range, relies on a structural battery pack that uses the same 4680-form-factor cells found in the Cybertruck.
However, Tesla engineers have completely redesigned the pack’s architecture—shifting from the flat, pancake-style modules typical in passenger vehicles to a compact, vertical cubic layout. This change isn’t just about cramming more energy into the chassis; it’s a targeted solution to one of electric trucking’s biggest headaches: range loss in cold climates.
Dan Priestley, Head of the Tesla Semi program, said:
“We’re using essentially the same cell out of Cybertruck, but our cars packs are more like a pancake. Whereas these are more like a cube. You get a lot of energy stored in a small space. You can only do this if you design the vehicle to be electric from the ground up.”
Here, in all its glory, is the exclusive first look at the massive @Tesla Semi factory.

In conventional EVs, battery packs are laid out horizontally in wide, flat arrays to fit under the floor. While this works for cars and even the Cybertruck’s structural pack, it exposes a large surface area to the elements.
Heat escapes quickly, especially overnight when the truck is parked. Cold temperatures slow chemical reactions inside lithium-ion cells, reducing available energy and forcing the vehicle to expend extra power warming the battery and cabin.
Real-world tests on vehicles like the Cybertruck show winter range losses of 20-40 percent, depending on conditions. For long-haul truck drivers operating in Canada, Scandinavia, or the northern U.S., this “silent killer” means unplanned stops, reduced payloads, and higher operating costs.
From personal experience, cold weather still impacts EV batteries even with various inventions and strategies that companies have come up with. In the cold Pennsylvania winter, charging was much more frequent for me due to range loss due to temperatures.
Tesla’s cubic battery pack flips the script. By arranging the 4680 cells in tall, dense vertical stacks, the pack minimizes external surface area relative to its volume—essentially turning the battery into its own thermal blanket.
Factory video from the Semi assembly line shows these large, yellow-green structural modules mounted directly onto the chassis, forming a near-cube shape.
The reduced exposure helps the pack retain heat generated during operation, keeping cells closer to their optimal temperature even after hours in sub-zero conditions.
The design doesn’t stop there. Tesla pairs the cubic pack with an advanced heat pump system that actively recycles thermal energy from the motors, brakes, and even ambient air.

Unlike passive systems in earlier EVs, this architecture transfers waste heat back into the battery, maintaining readiness for morning departures without draining the pack.
Executives have noted that the combination, cubic geometry plus intelligent thermal management, dramatically cuts overnight cooldown and range degradation, making the Semi viable for 24/7 fleet operations in harsh winters.
Beyond cold-weather performance, the redesigned pack integrates structurally with the truck’s frame, enhancing rigidity while simplifying assembly. Production footage shows workers installing the massive modules early in the line, signaling that the Semi’s battery is now a core chassis component rather than an add-on.
Using proven 4680 cells keeps costs down and leverages Tesla’s scaled manufacturing know-how from Cybertruck and Model Y lines.
Tesla’s focus on ramping up Semi output will lean on small innovative steps like this one. Truckers are not immune to traveling in cold weather conditions, and changes like this one will help make them more effective while also increasing output by logistics operators who choose to go all-electric with the Tesla Semi.

SpaceX is keeping the Space Station alive again this weekend
SpaceX’s Falcon 9 launches Northrop Grumman’s Cygnus NG-24 to the ISS with 11,000 pounds of cargo Saturday.
SpaceX is targeting April 11 for the launch of Northrop Grumman’s Cygnus XL cargo spacecraft to the International Space Station, carrying over 11,000 pounds of supplies, science hardware, and equipment for the Expedition 73 crew aboard. Liftoff is set for 7:41 a.m. ET from Space Launch Complex 40 at Cape Canaveral Space Force Station, with a backup window available April 12 at 7:18 a.m. ET.
The mission, officially designated NG-24 under NASA’s Commercial Resupply Services program, names its spacecraft the S.S. Steven R. Nagel in honor of the NASA astronaut who flew four Space Shuttle missions and logged over 723 hours in space before his death in 2014. Unlike SpaceX’s own Dragon capsule, which docks autonomously, Cygnus relies on NASA astronauts to capture it using a robotic arm before it is berthed to the space station’s module for unloading. When the mission wraps up around October, the Cygnus will depart loaded with station trash and burn up on reentry.
Countdown: America is going back to the Moon and SpaceX holds the key to what comes after
This is the second flight of the Cygnus XL configuration, which debuted on NG-23 in September 2025 and offers a roughly 20% increase in cargo capacity over the previous design. Northrop Grumman switched to Falcon 9 launches after its own Antares 230+ rocket was retired in 2023 following supply chain disruptions from the war in Ukraine.
The upcoming cargo includes a new module to advance quantum research, and an investigation studying blood stem cell production in microgravity with potential therapeutic applications on Earth.
The NG-24 mission is one piece of a much larger picture for SpaceX and the U.S. government. As Teslarati reported, SpaceX has become an indispensable launch provider for U.S. national security missions, picking up a $178.5 million Space Force contract in April 2026 to launch missile tracking satellites, while also holding roughly $4 billion in NASA contracts tied to the Artemis lunar program.
At a time when no other American rocket can match the Falcon 9’s combination of reliability, cost, and launch cadence, Saturday’s mission is a straightforward reminder of how much the U.S. government now depends on a single commercial provider to keep its astronauts supplied and its satellites flying.

Tesla hits FSD hackers with surprise move
In recent weeks, the company has begun remotely disabling FSD capabilities on affected vehicles, and in some instances, permanently revoking access even for owners who paid thousands of dollars for the feature.
Tesla is cracking down on hackers who have figured out a way to utilize third-party programs to activate Full Self-Driving (FSD) in their vehicles — despite the suite not being approved for use in their country.
Tesla has launched a sweeping enforcement campaign against owners using third-party hardware hacks to activate FSD software in countries where the advanced driver-assistance system remains unregulated or unapproved.

Reports of the crackdown have surfaced across Europe, China, Japan, South Korea, and the UK, marking a significant escalation in Tesla’s efforts to enforce regional software restrictions.
FSD is Tesla’s flagship supervised autonomy package, which is available in several countries across the world. Currently limited by regulatory hurdles, it has not received full approval in most markets outside of the United States due to various things, such as safety standards, data privacy, and local traffic laws.
However, the company is working to expand its availability globally. Nevertheless, Tesla has installed the necessary hardware on vehicles globally, but locks the features based on geographic location.
Some owners have taken accessing FSD into their own hands, using jailbreak or bypass devices.
These “jailbreak” tools, typically €500 USB-style modules that plug into the vehicle’s Controller Area Network (CAN) bus, intercept signals to spoof approvals and unlock FSD, including advanced navigation, Autopark, and Summon features.
Hackers in Poland, Ukraine, and elsewhere have distributed the devices, with some claiming they work on HW3 and HW4 vehicles and can be unplugged to restore stock settings. In China alone, over 100,000 owners reportedly installed such modifications.
Tesla’s response has been swift and uncompromising. Recently, the company began sending in-car notifications and emails warning owners that unauthorized modifications violate terms of service, compromise vehicle safety systems, and expose cars to cybersecurity risks.
The email communication read:
“Your vehicle has detected an unauthorized third-party device. As a precaution, some driver assistance functions have been disabled for safety reasons. A software update will be available soon. Once you install the update, some features may be enabled again.”
Vehicles detected using the hacks have had FSD capabilities remotely disabled without refund. In some cases, owners report permanent bans, even if they had legitimately purchased the software package.
Tesla’s hardline stance underscores its commitment to regulatory compliance and safety.
Tesla has long argued that unsupervised FSD requires rigorous validation, and premature activation could endanger drivers and bystanders.
The crackdown sends a clear-cut message to those who are bypassing the FSD safeguards, but there are greater implications for Tesla if something were to go wrong. This is an understandable way to protect the company’s reputation for its FSD suite.
