SpaceX-launched Uranus mission a top priority of new decadal survey
The National Academies of Sciences, Engineering, and Medicine have published their latest decadal survey of planetary science and astrobiology, revealing a recommendation that NASA prioritize the development of a flagship mission to Uranus baselined to launch on SpaceX’s Falcon Heavy rocket.
Known as the Uranus Orbiter and Probe or UOP, the mission proposal has been under development by a team of NASA, University of California, and Johns Hopkins University scientists and engineers for several years. In fact, a very similar concept ranked third in the Academies’ 2013-2022 decadal survey flagship recommendations, reiterating its central importance and potential value in the eyes of the survey’s dozens of contributors. According to its creators, in its latest iteration, the Uranus Orbiter and Probe have the potential to fully or partially answer 11 of the 12 primary questions the latest Decadal Survey structured itself around.
Additionally, the survey indirectly states that if it weren’t for the existence of one specific technology, it would have been a wash between a mission to Uranus or Neptune. That keystone: SpaceX’s Falcon Heavy rocket.
While the survey’s authors don’t explicitly point to SpaceX in the context of UOP, they do state that “a Uranus mission is favored because an end-to-end mission concept exists that can be implemented in the 2023-2032 decade on currently available launch vehicles.” In reality, there only appears to be one launch vehicle: Falcon Heavy. Three other alternatives do technically exist: United Launch Alliance’s (ULA) Vulcan Centaur, Blue Origin’s New Glenn, and NASA’s own Space Launch System (SLS).
NASA’s Europa Clipper orbiter – originally manifested on SLS but later moved to SpaceX’s Falcon Heavy to avoid major launch delays – has helped demonstrate that SLS isn’t viable for non-Artemis Program missions without massive production improvements and significant workarounds or design changes. While capable in many regards, Blue Origin’s reusable New Glenn rocket appears to have extremely poor performance beyond Earth orbit – well below what UOP requires – and is unlikely to launch before 2024 or 2025. It’s possible that an expendable New Glenn could suffice but Blue Origin has never mentioned the option and, even then, the rocket’s expendable performance could still fall short.
Finally, ULA’s expendable Vulcan Centaur rocket has yet to launch and its debut could easily slip into 2023. More importantly, according to official information provided by the company to a NASA-run performance calculator, even Vulcan’s most capable variant (VC6) with six solid rocket boosters (SRBs) simply doesn’t have the performance required to launch the Uranus Orbiter and Probe (7235 kg / 15,950 lb) on seven of the mission’s preferred trajectories. For three other secondary windows, Vulcan could potentially launch UOP but only with the inclusion of a Venus gravity assist that would require significant design changes to protect the spacecraft while traveling much closer to the sun.
According to NASA’s calculator, a fully-expendable Falcon Heavy rocket with a standard payload fairing could launch around 8.5-10 tons (18,700-22,000 lb) to UOP’s preferred trajectories, leaving a very healthy margin for spacecraft weight gain or launch underperformance and likely enabling a longer launch window for each opportunity.
If NASA agrees with the survey’s conclusions, decides to develop the Uranus Orbiter and Probe, and also plans on the Academies’ optimistic assumption of an ~18% budget increase on average from 2023 to 2032, work towards a preferred 2031 launch window could begin in earnest as early as 2024. Comprised of a namesake Orbiter and Probe, UOP would arrive in orbit around Uranus in late 2044 or early 2045 weighing around five metric tons (~11,000 lb). The primary science mission would begin by deploying a small atmospheric probe to directly analyze the composition and behavior of the planet’s exotic atmosphere, which is believed to be volatile, prone to vast and violent storms, and host to some of the most extreme winds in the solar system. The probe would weigh ~270 kilograms (~600 lb) and is only expected to survive for a few hours at most.
The orbiter, however, would continue on to tour the Uranian system for at least four years, observing and studying the ice giant and its rings, magnetosphere, and 27+ moons. Uranus itself resides in what may be the most common class of exoplanets in the universe, making a close study of it invaluable for exoplanet science as a whole. It’s also possible that – like several moons around Saturn and Jupiter – one or more Uranian moons have liquid water oceans created by tidal heating, adding to the list of extraterrestrial bodies that might feature habitable environments or alien life.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade
Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.
Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.
Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.
Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error.
More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report.
Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.
Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.
Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.
“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
