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.

SpaceX wants to catch Starship for launch 14, Elon Musk says
Just hours after Starship Flight 13 achieved a successful soft splashdown of its upper stage in the Indian Ocean on July 24, Elon Musk announced an ambitious next step for the company’s next launch of the rocket.
“Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on [the] next flight,” the SpaceX CEO posted on X on Friday.
That “next flight” is expected to be Flight 14. The plan involves returning the Starship upper stage, commonly called the “ship,” to the Starbase launch tower in Texas and catching it mid-air using the same mechanical “chopsticks” arms that have already proven themselves with the Super Heavy booster.

A successful catch would mark the first time an orbital-class upper stage has been recovered this way, advancing SpaceX’s goal of full and rapid reusability for the entire vehicle.
SpaceX has already demonstrated the tower-catch technique multiple times with Super Heavy. The first successful catch came on Flight 5 in October 2024, when Booster 12 was plucked from the sky by the Mechazilla arms. Subsequent flights, including those involving Boosters 14 and 15, repeated the feat. Several of those recovered boosters were later inspected, refurbished, and flown again, proving the system’s viability for quick turnaround.
Traditional reusable rockets, such as SpaceX’s own Falcon 9 or Blue Origin’s New Shepard, land on legs either on land or droneships. Rocket Lab has recovered its small Electron first stages by helicopter, but those are far lighter vehicles.
SpaceX Starship just nailed something it’s never done before
The China Academy of Launch Vehicle Technology (CALT), a subsidiary of the China Aerospace Science and Technology Corp. (CASC), completed a catch of its booster on July 10. They are the only entity besides SpaceX to attempt and complete the feat.
Flight 13 provided encouraging data. The ship executed a controlled reentry, flipped, and soft-landed intact in the ocean after deploying Starlink satellites, offering the first clear post-splashdown views of an undamaged heat shield. The Super Heavy booster, meanwhile, experienced a harder splashdown in the Gulf of Mexico.
Musk has previously stressed that ship catches would only follow multiple successful soft ocean landings to minimize risk of debris over land.
If Flight 14 succeeds, SpaceX would take a major stride toward routine, rapid reuse of both stages—critical for lowering launch costs and supporting ambitious plans for lunar and Mars missions. For now, teams are reviewing the Flight 13 data. Should everything check out, the next Starship flight could deliver one of the most spectacular recoveries in aerospace history.

Tesla to open source Model S and Model X designs and software
In a move echoing its earlier commitment to open innovation, Tesla CEO Elon Musk announced recently that the company plans to make the design and software of its Model S and Model X fully open source.
This follows the same approach Tesla took with its original Roadster, releasing all available design, engineering, and diagnostic materials in November 2023 so that “whatever we have, you now have.”
Just as Tesla made the original Roadster design & software open source, we plan to do the same with Model S & X
— Elon Musk (@elonmusk) July 24, 2026
The Model S, introduced in 2012, was Tesla’s first mass-produced vehicle and a groundbreaking luxury electric sedan. It offered impressive range, rapid acceleration, and over-the-air software updates that redefined expectations for electric cars.
The Model X, launched in 2015, built on that foundation as a high-performance electric SUV notable for its distinctive falcon-wing doors, spacious interior, and advanced safety features. Both models served as flagships that helped establish Tesla as a leader in the EV industry and popularized long-range battery-electric vehicles.
Production of the Model S and Model X was wound down earlier in 2026, with manufacturing ending in the second quarter. Tesla redirected the Fremont factory space previously used for these vehicles toward higher-priority projects, including Optimus humanoid robots and the Cybercab autonomous vehicle.
By the time of Musk’s open-source announcement, custom orders had closed and only remaining inventory was available.
Open-sourcing the designs and software offers several clear advantages. Owners of these aging but still capable vehicles gain better access to technical documentation, diagnostic tools, and software resources, making independent repairs and modifications easier and more affordable.
Independent repair shops and third-party specialists can support the large existing fleet without relying solely on Tesla’s service network. Enthusiasts and engineers can study real-world implementations of Tesla’s battery, powertrain, and software systems, potentially accelerating broader industry progress in electric mobility.
The step aligns with Tesla’s 2014 patent pledge and its overall mission to advance sustainable transport by sharing hard-won knowledge rather than locking it behind proprietary walls.
By releasing these materials now that the models have left production, Tesla ensures continued support for its early adopters while freeing internal resources for future technologies. The open-source release of the original Roadster already enabled simulations, community projects, and deeper technical understanding.
Extending that practice to the Model S and Model X should deliver similar benefits on a larger scale, helping keep these influential vehicles relevant and repairable for years to come

Tesla flexes incredible Robotaxi metric that skeptics will hate
Tesla flexed one incredible Robotaxi metric during the Q2 Earnings Call that skeptics have to hate to hear. The company’s platform has already driven more than 380,000 miles of unsupervised ride-hailing across several states with no notable incidents.
During the company’s Q2 Earnings Call on Wednesday, Vice President of AI, Ashok Elluswamy, said:
“First of all, I’d like to state that the Robotaxi program has been operating extremely well. Especially in terms of safety, the program has had an impeccable safety record. We have driven more than 380,000 miles of unsupervised Robotaxi, now across six cities in two different states. We have had zero notable incidents. Any reports have been of other actors impacting us when we were stationary. I like to emphasize how safe the operation has been so far. Zero notable incidents over 380,000 miles.”
Elluswamy’s claim over Robotaxi miles is a significant milestone for Tesla in the grand scheme, especially considering this is a sizeable number of miles without any incident.

— Tesla (@Tesla) July 22, 2026
Tesla’s self-driving approach is much different than that of other companies. Tesla has maintained that vision is the only thing needed to have a solid and effective self-driving suite. Many self-driving companies utilize things like LiDAR, sensors, and other elements to improve performance, but Elluswamy sent a jab at those who believe it’s needed.
“Historically, the so-called experts have always claimed that you need LiDARs, radars, HD maps, and the entire kitchen sink to drive safely. Here we show that such is not true. You can have safe, comfortable, and affordable autonomy with just cameras. This record should be a huge validation of Tesla’s entire AI approach.”
The feat of accumulating this many miles without any driver behind the wheel is impressive. The thing is, Tesla is also doing this across several different locations, with varying traffic rules, pedestrian levels, weather patterns, and other important factors.
While Tesla is not ready to roll out an unsupervised platform completely, it is a slow but steady indication that the company is well on its way to figuring things out.
The company’s attitude toward expansion is slow, safe, and controlled, and despite this huge milestone, it will still be some time until we see Tesla truly unleash unsupervised rides more aggressively.
