Carbon-Shelled Ruthenium Spheres Power a Greener Route to Hydrogen and Wastewater Purification

This study presents a laser-engineered ruthenium-carbon core-shell catalyst that dramatically lowers the energy barrier for hydrogen production. The material accelerates both the hydrogen evolution reaction and the hydrazine oxidation reaction, enabling large hydrogen yields at exceptionally low voltages. Its optimized Ru@C-200 configuration exhibits rapid reaction kinetics, high durability, and effective degradation of toxic hydrazine. When integrated into a hydrazine-splitting electrolyzer or a rechargeable zinc-hydrazine battery, the catalyst supports stable hydrogen output while simultaneously purifying contaminated hydrazine-containing streams. The findings highlight a promising strategy to combine green energy generation with pollutant removal using a single multifunctional electrocatalyst.

ISTJ-T: Making sense of the turbulence

ISTJ-T: Making sense of the turbulence

Yesterday I took the MBTI test again for the first time in eight months: ISTJ-T. I didn't think much of the four letters themselves - I've seen them enough times by now. What caught my attention was the last letter, a subtle change from A (assertive) to T (turbulent). It made me stop and think about when I became more worried and prone to overthinking, not because I believe in a personality test like it's my Roman Empire, but because some of the prompts in the test do reflect my current feelings toward my own stage of growth. For context, assertive people are usually calm and self-assured, while turbulent people tend to be more anxious and self-critical.Lately, I've noticed that much of my mood is tied to external validation. What I look forward to most days isn't necessarily rest after all my classes, hanging out with friends or even small forms of comfort. It's the possibility of opening my Gmail or Outlook and seeing the word "congratulations." An interview... An acceptance... Even just a results notification. Some sort of sign from the universe - or a selection committee - that I'm doing things right. It's embarrassing to admit how much power a subject line can have over my day. A rejection can sting for an hour or two, and then I move on to the next thing to chase after. On the surface, this looks like resilience, but sometimes it feels more like I'm just hopping from one potential source of validation to another, trying not to sit still long enough to feel the emptiness in between.I've been asking myself a lot of questions because of this. Am I not mature enough to be secure about my abilities? Am I not working hard enough or working in the wrong direction? None of these questions have clear answers. I know that facing these undesired results over and over isn't a bad thing at all. In some ways, it has made me less fragile. But it also feels like I'm avoiding processing my emotions and feelings by jumping into a new resume edit or application page. It feels unhealthy - like I'm constantly trying to prove myself to a ghost, and I'm never fully satisfied with who I am without some validation on paper to back it up.When I was in China this past summer for a summer camp, I thought I had become more confident in a place I spent 10 years of my life in. It was my first solo trip abroad. I was making decisions on my own and navigating the thousands of changes that had happened in the area over the last six years. I was eager to speak up about my experiences and excited to meet new people. I felt more independent and confident about myself. But after coming back, tripping into the cycle of classes, deadlines, applications, a lot of that confidence felt more shallow than I expected.It was easy to feel strong when my life looked different and I had distance from the routine here at Hopkins. In the familiar setting of school, with everything running aside me in their own directions, I was quickly reminded that confidence built only on small achievements and "new experiences" is still pretty fragile if it isn't rooted in something deeper. However, as I'm writing this article, I know that I am thinking about what I truly value and what these new experiences actually meant to me; it feels empowering to be able to let this out.I don't think ambition is the problem. I really want to see how far I can go in my twenties. These years are dramatic life transitions - from school to work, from being a student to being some undefined "adult in society," from being guided to guiding others. Every step feels a bit uncomfortable. What worries me more is how narrow my definition of "doing well" has become. If I only recognize my own growth when it's confirmed by someone else that I have never interacted with, I'm always going to be one email away from feeling like I'm not enough.I'm still trying to find ways to show myself that a lot of important growth occurs every day: learning to communicate effectively, setting boundaries or even just being content with not doing anything "productive" for a day. However, I'm still the same person checking my emails a little too often, constantly switching between being proud of myself and feeling like I have so much left to improve on. But I like to imagine my future self, maybe at 25 or 27, stumbling across my current state through this article. I hope she can look back at these words and smile, not because I figured everything out at 19 years old, but because I was honest enough to reflect and write this down and keep trying.I don't know what my life will look like then. I've always had an idealized vision of my future, but the more I experience, the more I realize how unpredictable life is. Every month, every year, I change a little. I meet new people, own new things, have new jobs and identities on campus. Maybe the one thing I can be confident about is this: I will keep going, keep learning and keep reflecting. Even if the MBTI says I'm "turbulent" now, that could just be another way of saying I'm still in the middle of becoming who I want to be.Linda Huang is a sophomore from Rockville, Md. majoring in Biomedical Engineering.

And the Mirrorball goes to... the algorithm

And the Mirrorball goes to... the algorithm

I recently finished the latest season of Dancing With the Stars. For those who weren't keeping up, Robert Irwin and his professional ballroom partner, Witney Carson, brought home the highly coveted Mirrorball trophy.Every year, a new season of this show premieres, and it becomes one of the only things I can talk about and the thing I look forward to the most on Tuesday evenings. This year, I was rooting for Whitney Leavitt from The Secret Lives of Mormon Wives. Sadly, I couldn't text "WHITNEY" to 21523 because voting is only available to the United States and Canada, and I'm in... Scotland. But I was supporting her from afar!In case Reality TV isn't your forte, or you decided to skip this season of Dancing With the Stars, Leavitt was eliminated during the semi-finals due to a lack of fans voting for her to stay in the competition. The third season of The Secret Lives of Mormon Wives had aired right before the semi-finals, and to say it hadn't been to Leavitt's benefit would be an understatement. But this was the first time I had seen a vast number of people on social media band together and actively decide to vote for every other couple except her (I think psychologists call this groupthink).While I am not one to lecture people on the dangers of obsessing over Reality TV or developing a black-and-white form of thinking, I had never quite seen how social media could be wielded as a destructive tool in real time.Naturally, as a Political Science student, I began to think about how easy it has become for our society to succumb to dangerous forms of thinking - seeing things not on a spectrum, but as either all-or-nothing. We've already begun to see this mentality infiltrate our politics.The recent government shutdown, the longest in U.S. history, serves as a prime example - Congressional Republicans largely refused to compromise with Democrats on a spending budget and vice versa. Throughout the entire shutdown, I would see comments on TikTok or Instagram either blaming Democrats for the shutdown entirely or insisting Republicans were single-handedly responsible for the stalemate. Very few people seemed willing to admit what political scientists seem to repeat like a broken record: that a gridlock is rarely the fault of one person or party, but rather the product of institutional incentives, polarized media ecosystems and elected officials who ultimately benefit from refusing to budge.But that kind of nuance doesn't trend.What does trend, however, are the posts that declare "This side is evil" or "That side ruined everything." Social media rewards outrage, certainty and villians to point at, because life is always a little easier when you have someone else to blame. And once the algorithm finds the narrative you're most likely to engage with, it feeds it back to you until your entire worldview feels confirmed - no matter how distorted it becomes.This is how we get from voting against a contestant on Dancing With the Stars because TikTok told us she's "problematic" and a "horrible person" (when most of us don't really know her at all), to voters insisting that one political party alone is responsible for government dysfunction. It's the same impulse dressed up in different stakes: we want someone to blame, someone to cancel, someone to remove, so we don't have to wrestle with complexity.And the political system thrives on this. Politicians don't get reelected if they make things complicated for their constituency. They know that if they provide a simple enemy - a person, a party, a scapegoat - social media will do the rest of the work for them. Outrage spreads faster than any policy briefing ever could.In the end, maybe the real Mirrorball trophy goes to the platforms themselves. They've mastered the art of choreographing our attention, pushing us into neat little corners where the world makes sense only if there's a hero and a villain, a winner and a loser, a right and a wrong. No shades of gray and definitely no middle ground.But politics - like people, like ballroom dance - has always lived in the in-between: the messy, complicated, imperfect spaces where the real work actually happens. We need to dive into the nitty-gritty and actually understand what is going on. Or else we risk becoming victims of the very system we claim we want to fix.If we want a healthier political culture, maybe the first step is learning to log off once in a while and touch some grass. Remember that not every conflict needs a villain. It takes more energy to think about nuances and retrain yourself to look at the shades of gray, but it's worth it.Sometimes it's a controversial semi-final round of Dancing With the Stars, a broken Congress or a system that needs more cooperation and less choreography.And unfortunately, you can't fix all that by texting "WHITNEY" to 21523.Alyssa Gonzalez is a junior majoring in Political Science and International Studies.Her column approaches the political atmosphere through an individual lens, grounding the conversation in empathy and clarity in an attempt to humanize the field.

The Top 6 Biomedical Stories of 2025

The Top 6 Biomedical Stories of 2025

IEEE Spectrum’s most popular biomedical stories of the last year centered both on incorporating new technologies and revamping old ones. While AI is all the rage in most sectors—including biomed, with applications like an in-brain warning system for worsening mental health and a model to estimate heart rate in real time—biomedical news this past year has also focused on legacy technologies. Tech like Wi-Fi, ultrasound, and lasers have all made comebacks or found new uses in 2025.Whether innovation stems from new tech or old, IEEE Spectrum will continue to cover it rigorously in 2026.1. Next-Gen Brain Implants Offer New Hope for Depression Georgia Institute of Technology, Icahn School of Medicine at Mt. Sinai and TeraPixel When Patricio Riva Posse, a psychiatrist at Emory University School of Medicine, realized that his patient’s brain implants were sending him signals about her worsening depression before she even recognized anything was wrong, he wished he could have taken action sooner. That experience led him and colleagues to develop “an automatic alarm system” for signs of changing mental health. The tool monitors brain signals in real time, using implants to record electrical impulses, and AI to analyze the outputs and flag warning signs of relapse. Other research groups across the United States are experimenting with different ways to use these stimulating brain implants to help treat depression, both with and without the help of AI. “There are so many levers we can press here,” neurosurgeon Nir Lipsman says in the article.2. These Graphene Tattoos Are Actually Biosensors Dmitry Kireev/University of Massachusetts Amherst In Dmitry Kireev’s lab at the University of Massachusetts Amherst, researchers are developing imperceptibly thin graphene tattoos capable of monitoring your vital signs and more. “Electronic tattoos could help people track complex medical conditions, including cardiovascular, metabolic, immune system, and neurodegenerative diseases. Almost half of U.S. adults may be in the early stages of one or more of these disorders right now, although they don’t yet know it,” he wrote in an article for IEEE Spectrum.How does it work? Graphene is conductive, strong, and flexible, able to measure features like heart rate and the presence of certain compounds in sweat. For now, the tattoos need to be plugged into a regular electronic circuit, but Kireev hopes that they will soon be integrated into smartwatches, and thus simpler to wear.3. How Wi-Fi Signals Can Be Used to Detect Your Heartbeat Erika Cardema/UC Santa Cruz Wi-Fi can do more than just get you connected to the internet—it can help monitor your heart inexpensively and without requiring constant physical contact. The new approach, called Pulse-Fi, uses an AI model to analyze heartbeats to estimate heart rate in real time from up to 10 feet away. The system is low cost, totaling around US $40, easy to deploy, and doesn’t introduce discomfort. It also works regardless of the user’s posture and in all kinds of environments. Katia Obraczka, a computer scientist at the University of California, Santa Cruz who led the development of Pulse-Fi, says the team plans to commercialize the technology.4. Doctors Could Hack the Nervous System With Ultrasound Shonagh Rae Sangeeta S. Chavan and Stavros Zanos, biomedical researchers at the Institute of Bioelectronic Medicine in New York, hypothesize that ultrasound waves may activate neurons, offering “a precise and safe way to provide healing treatments for a wide range of both acute and chronic maladies,” as they write in an article for Spectrum. Targeted ultrasound could then serve as a treatment for inflammation or diabetes, instead of medication with wide-ranging side effects, they say.It works by vibrating a neuron’s membrane and “opening channels that allow ions to flow into the cell, thus indirectly changing the cell’s voltage and causing it to fire,” they write. The authors think that activating specific neurons can help address the root causes of specific illnesses.5. Scientists Shine a Laser Through a Human Head Extreme Light group/University of Glasgow If a doctor wants to see inside your head, they have to decide whether they want to do so cheaply or deeply—an electroencephalograph is inexpensive, but doesn’t penetrate past the outer layers of the brain, while functional magnetic resonance imaging (fMRI) is expensive, but can see all the way in. Shining a laser through a person’s head seems like the first step towards technology that accomplishes both.For many years, this kind of work has seemed impossible because the human head is so good at blocking light, but researchers have now proven that lasers can send photons all the way through. “What was thought impossible, we’ve shown to be possible.

Grid-Scale Bubble Batteries Will Soon Be Everywhere

Grid-Scale Bubble Batteries Will Soon Be Everywhere

This giant bubble on the island of Sardinia holds 2,000 tonnes of carbon dioxide. But the gas wasn’t captured from factory emissions, nor was it pulled from the air. It came from a gas supplier, and it lives permanently inside the dome’s system to serve an eco-friendly purpose: to store large amounts of excess renewable energy until it’s needed.Developed by the Milan-based company Energy Dome, the bubble and its surrounding machinery demonstrate a first-of-its-kind “CO2 Battery,” as the company calls it. The facility compresses and expands CO2 daily in its closed system, turning a turbine that generates 200 megawatt-hours of electricity, or 20 MW over 10 hours. And in 2026, replicas of this plant will start popping up across the globe.We mean that literally. It takes just half a day to inflate the bubble. The rest of the facility takes less than two years to build and can be done just about anywhere there’s 5 hectares of flat land.The first to build one outside of Sardinia will be one of India’s largest power companies, NTPC Limited. The company expects to complete its CO2 Battery sometime in 2026 at the Kudgi power plant in Karnataka, in India. In Wisconsin, meanwhile, the public utility Alliant Energy received the all clear from authorities to begin construction of one in 2026 to supply power to 18,000 homes.And Google likes the concept so much that it plans to rapidly deploy the facilities in all of its key data-center locations in Europe, the United States, and the Asia-Pacific region. The idea is to provide electricity-guzzling data centers with round-the-clock clean energy, even when the sun isn’t shining or the wind isn’t blowing. The partnership with Energy Dome, announced in July, marked Google’s first investment in long-duration energy storage.“We’ve been scanning the globe seeking different solutions,” says Ainhoa Anda, Google’s senior lead for energy strategy, in Paris. The challenge the tech giant has encountered is not only finding a long-duration storage option, but also one that works with the unique specs of every region. “So standardization is really important, and this is one of the aspects that we really like” about Energy Dome, she says. “They can really plug and play this.”Google will prioritize placing the Energy Dome facilities where they’ll have the most impact on decarbonization and grid reliability, and where there’s a lot of renewable energy to store, Anda says. The facilities can be placed adjacent to Google’s data centers or elsewhere within the same grid. The companies did not disclose the terms of the deal.Anda says Google expects to help the technology “reach a massive commercial stage.”Getting creative with long-duration energy storageAll this excitement is based on Energy Dome’s one full-size, grid-connected plant in Ottana, Sardinia, which was completed in July. It was built to help solve one of the energy transition’s biggest challenges: the need for grid-scale storage that can provide power for more than 8 hours at a time. Called long-duration energy storage, or LDES in industry parlance, the concept is the key to maximizing the value of renewable energy.When sun and wind are abundant, solar and wind farms tend to produce more electricity than a grid needs. So storing the excess for use when these resources are scarce just makes sense. LDES also makes the grid more reliable by providing backup and supplementary power.The problem is that even the best new grid-scale storage systems on the market—mainly lithium-ion batteries—provide only about 4 to 8 hours of storage. That’s not long enough to power through a whole night, or multiple cloudy and windless days, or the hottest week of the year, when energy demand hits its peak. After the CO2 leaves the dome, it is compressed, cooled, reduced to a liquid, and stored in pressure vessels. To release the energy, the process reverses: The liquid is evaporated, heated, expanded, and then fed through a turbine that generates electricity. Luigi AvantaggiatoLithium-ion battery systems could be increased in size to store more and last longer, but systems of that size usually aren’t economically viable. Other grid-scale battery chemistries and approaches are in development, such as sodium-based, iron-air, and vanadium redox flow batteries. But the energy density, costs, degradation, and funding complications have challenged the developers of those alternatives.Researchers have also experimented with storing energy by compressing air, heating up blocks or sand, using hydrogen or methanol, pressurizing water deep underground, and even dangling heavy objects in the air and dropping them. (The creativity devoted to LDES is impressive.) But geologic constraints, economic viability, efficiency, and scalability have hindered the commercialization of these strategies.The tried-and-true grid-scale storage option—pumped hydro, in which water is pumped between reservoirs at different elevations—lasts for decades and can store thousands of megawatts for days. But these systems require specific topography, a lot of land, and can take up to a decade to build.CO2 Batteries check a lot of boxes that other approaches don’t. They don’t need special topography like pumped-hydro reservoirs do. They don’t need critical minerals like electrochemical and other batteries do. They use components for which supply chains already exist. Their expected lifetime stretches nearly three times as long as lithium-ion batteries. And adding size and storage capacity to them significantly decreases cost per kilowatt-hour. Energy Dome expects its LDES solution to be 30 percent cheaper than lithium-ion.China has taken note. China Huadian Corp. and Dongfang Electric Corp. are reportedly building a CO2-based energy-storage facility in the Xinjiang region of northwest China. Media reports show renderings of domes but give widely varying storage capacities—including 100 MW and 1,000 MW. The Chinese companies did not respond to IEEE Spectrum’s requests for information.“What I can say is that they are developing something very, very similar [to Energy Dome’s CO2 Battery] but quite large in scale,” says Claudio Spadacini, Energy Dome’s founder and CEO. The Chinese companies “are good, they are super fast, and they have a lot of money,” he says.Why is Google investing in CO2 Batteries?When I visited Energy Dome’s Sardinia facility in October, the CO2 had just been pumped out of the dome, so I was able to peek inside. It was massive, monochromatic, and pretty much empty. The inner membrane, which had been holding the uncompressed CO2, had collapsed across the entire floor. A few pockets of the gas remained, making the off-white sheet billow up in spots.Meanwhile, the translucent outer dome allowed some daylight to pass through, creating a creamy glow that enveloped the vast space. With no structural framing, the only thing keeping the dome upright was the small difference in pressure between the inside and outside air.“This is incredible,” I said to my guide, Mario Torchio, Energy Dome’s global marketing and communications director.“It is. But it’s physics,” he said.Outside the dome, a series of machines connected by undulating pipes moves the CO2 out of the dome for compressing and condensing. First, a compressor pressurizes the gas from 1 bar (100,000 pascals) to about 55 bar (5,500,000 pa). Next, a thermal-energy-storage system cools the CO2 to an ambient temperature. Then a condenser reduces it into a liquid that is stored in a few dozen pressure vessels, each about the size of a school bus. The whole process takes about 10 hours, and at the end of it, the battery is considered charged.To discharge the battery, the process reverses. The liquid CO2 is evaporated and heated. It then enters a gas-expander turbine, which is like a medium-pressure steam turbine. This drives a synchronous generator, which converts mechanical energy into electrical energy for the grid. After that, the gas is exhausted at ambient pressure back into the dome, filling it up to await the next charging phase. Energy Dome engineers inspect the dryer system, which keeps the gaseous CO2 in the dome at optimal dryness levels at all times.Luigi AvantaggiatoIt’s not rocket science. Still, someone had to be the first to put it together and figure out how to do it cost-effectively, which Spadacini says his company has accomplished and patented. “How we seal the turbo machinery, how we store the heat in the thermal-energy storage, how we store the heat after condensing...can really cut costs and increase the efficiency,” he says.The company uses pure, purpose-made CO2 instead of sourcing it from emissions or the air, because those sources come with impurities and moisture that degrade the steel in the machinery.What happens if the dome is punctured?On the downside, Energy Dome’s facility takes up about twice as much land as a comparable capacity lithium-ion battery would. And the domes themselves, which are about the height of a sports stadium at their apex, and longer, might stand out on a landscape and draw some NIMBY pushback.And what if a tornado comes? Spadacini says the dome can withstand wind up to 160 kilometers per hour. If Energy Dome can get half a day’s warning of severe weather, the company can just compress and store the CO2 in the tanks and then deflate the outer dome, he says.If the worst happens and the dome is punctured, 2,000 tonnes of CO2 will enter the atmosphere. That’s equivalent to the emissions of about 15 round-trip flights between New York and London on a Boeing 777. “It’s negligible compared to the emissions of a coal plant,” Spadacini says. People will also need to stay back 70 meters or more until the air clears, he says.Worth the risk? The companies lining up to build these systems seem to think so.

Engineering the First Reusable Launchpads on the Moon

Engineers need good data to build lasting things. Even the designers of the Great Pyramids knew the limestone they used to build these massive structures would be steady when stacked on top of one another, even if they didn’t have tables of the compressive strength of those stones. But when attempting to build structures on other worlds, such as the Moon, engineers don’t yet know much about the local materials. Still, due to the costs of getting large amounts of materials off of Earth, they will need to learn to use those materials even for critical applications like a landing pad to support the landing / ascent of massive rockets used in re-supply operations. A new paper published in Acta Astronautica from Shirley Dyke and her team at Purdue University describes how to build a lunar landing pad with just a minimal amount of prior knowledge of the material properties of the regolith used to build it.

Rare Cube-Shaped Skull Found in Mexico Reveals New History

INAHA cube-shaped human skull discovered by researchers in Mexico could yield new insights into an ancient cultural practice known as “intentional cranial deformation.” The skull belonged to a 40-year-old man who lived in the Sierra Madre Oriental mountain range more than 1,000 years ago, according to a translated press release from Mexico’s National Institute of Anthropology and History (INAH). The institute said the practice was carried out during a child’s early years, using boards and bandages wrapped around the skull to sculpt it as the child developed. “Not only was intentional cranial deformation identified for the first time for this type of site, but also a variant [was found] with respect to the models recognized in Mesoamerica not reported until now in the area,” anthropologist Jesús Ernesto Velasco González said, according to the release. He explained that the square shape of the skull was different than the typical “conical” shape seen elsewhere in the region.Read it at PeopleRead more at The Daily Beast.

We Now Know How Much Faster Clocks Will Run on Mars

We Now Know How Much Faster Clocks Will Run on Mars

The most precise timekeepers ever made, atomic clocks, might one day help robotic and crewed missions on Mars stay in sync with each other, as well as enable the equivalent of GPS on the red planet. But, as Einstein made clear, time flows at different rates depending on where you are. Now scientists have estimated the speed at which clocks tick on Mars—an average of 477 millionths of a second faster than clocks on Earth per day. These findings might suggest ways in which future networks on Mars can avoid problems such clock differences might produce.Atomic clocks monitor the vibrations of atoms. Optical atomic clocks, which use intersecting laser beams to entrap and monitor the atoms, are currently accurate down to 1 attosecond, or a billionth of a billionth of a second. These clocks have many applications besides keeping time—for example, they are key to the precisely timed signals that GPS and other global navigation satellite systems rely on to help users pinpoint their own locations.However, because the gravity of massive objects warps spacetime, the rate of time passes different at different gravitational field strengths. In other words, the weaker a planet’s gravitational pull, the faster clocks on its surface tick. And the average strength of Mars’s gravitational pull is roughly three times as weak as Earth’s.Mars Timekeeping and GPS TechnologyIn 2024, scientists at the National Institute of Standards and Technology (NIST) in Boulder, Colo. estimated the rate at which clocks ticked on the moon, which has an average gravitational pull about six times as weak as Earth’s. Given NASA’s plans for missions to Mars, the researchers have now analyzed timekeeping on Mars and detailed their research in a study published online on 1 December in The Astronomical Journal.“With an understanding of these relativistic effects comes the hope that humans will someday become an interplanetary species,” says Neil Ashby, a professor emeritus of physics at the University of Colorado, Boulder, and an affiliate of NIST.Using years of data collected from previous Mars missions, the scientists calculated the strength of gravity on the Martian surface. They also had to account for the how the gravitational effects of the sun and the other planets on Mars changed over time over the course of the Red Planet’s eccentric, elongated orbit.Although clocks on Mars will on average tick 477 microseconds faster than on Earth per day, this value can increase or decrease by as much as 226 microseconds per day over the course of the Martian year, depending on effects from its celestial neighbors. Such variations could prove challenging when it comes to coordinating missions on Mars.“Microseconds matter in navigation and communications,” says Bijunath Patla, a theoretical physicist at NIST. “Current 5G networks rely on microsecond-level synchronization. GPS clocks are synchronized to a few nanoseconds.”This difference between Mars and Earth in clock speeds has not been a problem in past missions, because they relied “on one-way radio communication from ground stations on Earth and Mars,” Ashby says. “There was no need for rovers to be synchronized with each other.”This new research “is important if you have multiple assets on Mars and they need to be in sync with each other and independent from Earth,” Patla says. “This could be important in returning to the same location for further exploration or prospecting.”One possible way for Martian missions to deal with this difference between Earth and Martian clocks may be to deploy a GPS-like constellation of satellites around the planet so that both rover clocks and constellation clocks “share a common, Mars-centric system time,” Ashby says.In such a scheme, only small local corrections would be needed to be applied when comparing clocks on Mars. “‘Mars system time’ would remain internally self-consistent and largely independent of Earth, and only the Earth-Mars link would require periodic calibration to account for the larger interplanetary offsets,” Patla says.
