In January 2023, Tara Sweeney’s plane landed on Thwaites Glacier, a 74,000-square-mile mass of frozen water in West Antarctica. She arrived with an international research team to study the glacier’s geology and ice fabric, and how its ice melt might contribute to sea level rise. But while near Earth’s southernmost point, Sweeney kept thinking about the moon.

“It felt every bit of what I think it will feel like being a space explorer,” said Sweeney, a former Air Force officer who’s now working on a doctorate in lunar geology at the University of Texas at El Paso. “You have all of these resources, and you get to be the one to go out and do the exploring and do the science. And that was really spectacular.”

That similarity is why space scientists study the physiology and psychology of people living in Antarctic and other remote outposts: For around 25 years, people have played out what existence might be like on, or en route to, another world. Polar explorers are, in a way, analogous to astronauts who land on alien planets. And while Sweeney wasn’t technically on an “analog astronaut” mission — her primary objective being the geological exploration of Earth — her days played out much the same as a space explorer’s might.

For 16 days, Sweeney and her colleagues lived in tents on the ice, spending half their time trapped inside as storms blew snow against their tents. When the weather permitted, Sweeney snowmobiled to and from seismometer sites, once getting caught in a whiteout that, she said, felt like zooming inside a ping-pong ball.

On the glacier, Sweeney was always cold, sometimes bored, often frustrated. But she was also alive, elated. And she felt a form of focus that eluded her on her home continent. “I had three objectives: to be a good crewmate, to do good science, and to stay alive,” she said. “That’s all I had to do.”

None of that was easy, of course. But it may have been easier than landing back on the earth of El Paso. “My mission ended, and it’s over,” she said. “And how do I process through all these things that I’m feeling?”

Then, in May, she attended the 2023 Analog Astronaut Conference, a gathering of people who simulate long-term space travel from the relative safety and comfort of Earth. Sweeney had learned about the event when she visited an analog facility in the country of Jordan. There, she’d met one of the conference’s founders, Jas Purewal, who invited her to the gathering.

The meeting was held, appropriately, at Biosphere 2, a glass-paneled, self-contained habitat in the Arizona desert that resembles a 1980s sci-fi vision of a space settlement — one of the first facilities built, in part, to understand whether humans could create a habitable environment on a hostile planet.

A speaker at the conference had spent eight months locked inside a simulated space habitat in Moscow, Russia, and she talked about how the post-mission period had been hard for her. The psychological toll of reintegration became a chattering theme throughout the whole meeting. Sweeney, it turned out, wasn’t alone.

Across the world, around 20 analog space facilities host people who volunteer to be study subjects, isolating themselves for weeks or months in polar stations, desert outposts, or even sealed habitats inside NASA centers. These places are intended to mimic how people might fare on Mars or the moon, or on long-term orbital stations. Such research, scientists say, can help test out medical and software tools, enhance indoor agriculture, and address the difficulties analog astronauts face, including, like Sweeney’s, those that come when their “missions” are over.

Lately, a community of researchers has started to make the field more formalized: laying out standards so that results are comparable; gathering research papers into a single database so investigators can

Balloons will surf wind currents to track wildfires

240717 microballoon embed1 scaled

This August, strange balloons will drift high above Colorado. These airy aircraft, launched from the back of a pickup truck, will be equipped with sensors that can measure heat on the ground, pinpointing new wildfire outbreaks from above.

The company behind the balloons, called Urban Sky, also plans to use them to understand conditions on the ground before fires start. Approximately 237,500 acres burn in Colorado annually, according to 2011–2020 data from the Rocky Mountain Area Coordination Center. The hope is that this new high-altitude tool might allow humans to manage—or at least understand—those blazes better.

“Wildfire is a natural part of ecosystems,” says Michael Falkowski, manager of the wildland fire programs at NASA. But climate change has proved to be an accelerant, rendering fires bigger, more intense, and more frequent. At the same time, more people are living closer to wild spaces, and the US’s history of fire suppression, which has crowded forests and left old and dead vegetation sitting around, is fanning the flames.

To deal with modern fires, Falkowski says, researchers and fire agencies have to gather data before those fires start and after they’re done smoldering, not just as they’re burning. That makes it possible to understand the risks ahead of time and try to mitigate them, track ongoing blazes, and understand the threats fires pose to communities and the environment.

Before a fire takes hold, researchers can map vegetation and estimate how wet or dry it is. During a fire, they can map where and how hot the activity is. When it’s all over, they can assess the severity of the burn and track air quality.

Still, the most acute phase is obviously the one when the fire is actually burning. In the heat of that moment, it can be hard to get a handle on when and where, exactly, the fire is taking hold. Satellites do some of that work, surveying large areas all at once. But the primary governmental satellites produce pictures with pixels around 300 meters across, and they can’t always get a super timely look at a given spot, since their view is limited by their orbit.

Airplanes and helicopters can map a fire’s extent in more detail, but they’re expensive to operate and dangerous to fly. They have to coordinate with other aircraft and have smaller views, being closer to the ground. They’re also a limited resource. 

Urban Sky aims to combine the advantages of satellites and aircraft by using relatively inexpensive high-altitude balloons that can fly above the fray—out of the way of airspace restrictions, other aircraft, and the fire itself. The system doesn’t put a human pilot at risk and has an infraredsensor system called HotSpot that provides a sharp, real-time picture, with pixels 3.5 meters across. “We targeted that resolution with the goal of being able to see a single burning tree,” says Jared Leidich, chief technology officer at Urban Sky. “And so that would show up essentially as one pixel—one hot pixel.” The company has some competition: Others, like Aerostar and LUX Aerobot, also make balloons that can monitor wildfires.

The Urban Sky team has launched balloons in previous tests, but in August, the technology will monitor potential fires for an actual (unspecified) customer. Sending the balloon-lofted HotSpot up will be a surprisingly simple affair, thanks to the balloon’s relatively small size: While the company makes several sizes, the original is about as big as a van at launch, inflating to the size of a small garage once it’s aloft and surrounded by lower-pressure air. The Urban Sky team uses weather software to calculate where to launch a balloon so that it will drift over the fire at the right elevation. Then the team packs one up, along with compressed helium or hydrogen gas, and drives a truck out to that location. The balloon is hooked onto a mast jutting from the vehicle, filled up with the lighter-than-air molecules,

The Download: Windows’ CrowdStrike outage, and wildfire-tracking balloons

This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

A widespread Windows outage is affecting airlines, banks, and TV broadcasters

What’s happening? Windows PCs have crashed around the world, bringing airlines, major banks, TV broadcasters, healthcare providers and other businesses to a standstill. Airlines including United Airlines, Delta, and American Airlines have been forced to ground and delay flights, stranding passengers in airports, while UK broadcaster Sky News was temporarily pulled off air.

Banking customers in Europe, Australia and India have been unable to access their online accounts, and traders have been unable to operate as normal.

What caused it? The issue originates from a faulty update from cybersecurity provider CrowdStrike, which has knocked affected servers and PCs offline and caused Windows workstations to display ‘blue screens of death’ when users attempt to boot them. Mac and Linux hosts are not affected.

When will it be fixed?

George Kurtz, CEO of Crowdstrike, said that the company was actively working with customers impacted by the defect, found in a single content update for Windows hosts.

“This is not a security incident or cyberattack,” he said in a statement on X. “The issue has been identified, isolated and a fix has been deployed. We refer customers to the support portal for the latest updates and will continue to provide complete and continuous updates on our website.”

However, that doesn’t appear to help computers that are already affected, meaning that companies’ IT teams may have to follow a manual workaround that CrowdStrike sent to its customers earlier this morning, Reuters reports.

Why we need safeguards against genetic discrimination

Tens of millions of people have shipped their DNA off to companies offering to reveal clues about their customers’ health or ancestry, or had genetic tests as part of their clinical care.

It isn’t always clear how secure this data is, or who might end up getting their hands on it—and how that information might affect people’s lives. Scientists, ethicists and legal scholars aren’t clear on the matter either. They are still getting to grips with what genetic discrimination entails—and how we can defend against it.

Companies need to stop taking the easy way out on climate goals

This article is from The Spark, MIT Technology Review’s weekly climate newsletter. To receive it in your inbox every Wednesday, sign up here

Corporate climate claims can be confusing—and sometimes entirely unintuitive.

Tech giants Amazon and Google both recently released news about their efforts to clean up their climate impact. Both were a mixed bag, but one bit of news in particular made me prick up my ears. Google’s emissions have gone up, and the company stopped claiming to be “net zero” (we’ll dig into this term more in a moment). Sounds bad, right? But in fact, one might argue that Google’s apparent backslide might actually represent progress for climate action.

My colleague James Temple dug into this news, along with the recent Amazon announcement, for a story this week. Let’s take a sneak peek at what he found and untangle why corporate climate efforts can be so tricky to wrap your head around. 

To make sense of these recent announcements, the most important phrase to understand is “net-zero emissions.”

Companies produce greenhouse-gas emissions by making products, transporting them around, or just using electricity. Some corporate leaders may want to reduce those emissions so they can be a smaller part of the climate-change problem (or brag about their progress). Net-zero emissions refers to the point at which the emissions a company produces are canceled out by those it eliminates. But very different paths can all lead to that point.

One way to get rid of emissions is to take actions to reduce them in your operations. Imagine, for example, Amazon replacing its delivery trucks with EVs or building solar panels on warehouses.

This sort of direct action tends to be hard and expensive, and it’s probably impossible for any company to totally wipe out all its emissions right now, given that so much of our economy still relies on fossil fuels. So to reach net zero, many companies choose to disappear their emissions with math instead.

A company might buy carbon credits or renewable-energy credits, essentially paying someone to make up for its own climate impact. That might mean giving a nonprofit money to plant some trees, which suck up and store carbon, or funneling funds to developers and claiming that more renewables projects will get built as a result.

Not all credits are all bad—but often, carbon offsets and renewable-energy credits reflect big claims with little to back them up. And if companies are going after a net-zero label for their business, they may be incentivized to buy cheap credits, even if they don’t actually deliver on claims. 

As James puts it in his story, “Corporate sustainability officers often end up pursuing the quickest, cheapest ways of cleaning up a company’s pollution on paper, rather than the most reliable ways of reducing its emissions in the real world.”

This sort of issue is why I tend to be suspicious of companies that claim to have already achieved net-zero emissions or 100% renewable energy. Cleaning up emissions is hard, and if you’ve already claimed victory, I’d say the odds are good that you’re taking an easy way out.

Which brings us to Google’s news. Google has claimed that its operations have operated with net-zero emissions since 2007. Now it’s not claiming that anymore—not really because it suddenly decided to take huge steps back in how it operates, but because it’s stopped buying carbon offsets on a massive scale. Instead, it’s focusing on investing in other ways to tackle emissions.

So what’s the next step for big companies looking to have a material impact on climate action? James has us covered again: In a 2022 story, he laid out six potential ways to rethink corporate climate goals. 

Instead of buying up credits, companies can instead put that money toward investing in permanent carbon removal. Developing more reliable methods of pulling climate pollution out of the atmosphere and locking it away might be more expensive, but investing in those efforts will help the market mature and support companies that need commitments. 

Companies can also contribute money to research and development for areas that are difficult to decarbonize—think aviation, shipping, steel, and cement. Those sectors touch basically every industry, so helping them make progress could be a worthy use of dollars. 

If there’s one takeaway in this tangle of news, I’d say that we could all ask more questions and dig a little deeper into claims from big corporations. Remember, if something sounds too good to be true, it probably is.
