Mars colony simulations: Crew may revolt without strong interplanetary communication

As extraterrestrial settlers gain independence from mission control, they could test the line between healthy autonomy and closed-off anarchy.

Earlier this month, six people began their tenure in an immersive experiment that’s either your greatest dream or your worst nightmare: They’re living in a simulated extraterrestrial colony while being monitored by its builders. It’s part of Project Sirius, an eight-month off-world settlement test taking place in Moscow.

Given the rampant interest in colonizing other planets — especially from SpaceX CEO Elon Musk — scientists behind these experiments are learning what physical and psychological consequences could be in store for future Martian or lunar settlers. And even though 2021’s Sirius simulation just started on Nov. 4, there’s already a good chunk of data to work with from tests in 2017 and 2019.

Among those analyzing the specifics, one research team has noted two striking outcomes: Members of the «off-Earth society» grew increasingly autonomous, and they progressively communicated their feelings less often with mission control. The researchers published their findings Nov. 9 in the journal Frontiers in Physiology.

At face value, strong independence seems promising in a potential Martian society. If settlers perceive full control of their mission, they’d function confidently on their own and work collaboratively, drawing on their comfort with one another. That could benefit later interplanetary endeavors by easing individual anxiety and enhancing group cohesion for carrying out protocols.

That was one of the surprising findings of the study. «The communication characteristics of crew members with different personalities, genders and cultures became more similar during the mission,» said co-author Dmitry Shved of the Russian Academy of Sciences and the Moscow Aviation Institute.

But on a deeper level, letting go of mission control’s hand invites some challenges.

«The negative side is that the mission control loses the possibility to understand the needs and problems of the crew, which consequently hinders mission control’s ability to provide support,» Shved said.

Taking it a step (or five) further, if the crew achieves a super high level of autonomy and cohesion, according to Shved, there’s another potential concern — they might seek complete detachment from external governing structures. Basically, Martian-humans could revolt from Earthlings.

But not to worry, at least not too much. «During the period when the Mars colonies will still be dependent on resupplies and people coming from Earth,» he said, «the probability of severance of diplomatic relations seems rather low.»

Ground control to Major Tom

Project Sirius is all-encompassing. Each simulation gave participants the whole nine yards of space «colonization» to unlock precise details of off-world group dynamics.

First, subjects underwent a realistic takeoff and landing — rockiness and all. Then they were immediately isolated in chambers from the outside world. The brave souls also weren’t given an abundance of supplies, were told to utilize onboard greenhouses and even experienced signal lags while talking to mission control.

After the respective 17-day and 120-day periods of 2017’s and 2019’s experiments, Shved’s team began observing how communication between the experimental crews and mission control evolved over time.

«The crews in simulated missions tended to reduce their communication with the mission control during the isolation,» Shved said, «sharing their needs and problems less and less — with rare exceptions such as important mission events, like landing simulation.»

On the other hand, over the course of the mission there was a convergence of communication styles among Project Sirius crew members and an increase in crew cohesion, even though the crew composition was diverse by gender and cultural background, with pronounced individual differences, according to Shved.

Regarding gender, the team’s study indicated that those who identified as women reacted differently to stress than those who identified as men based on speech acoustic indicators, facial expressions and content analysis of their messages. Unlike men, women manifested both joy and sadness facially, and showcased stress less audibly in speech, Shved said.

That data coincides with stress management gender differences for space colonization in data obtained by Sheryl Bishop of California’s Space Surgery Institute, according to Shved. Her work was derived from results of a study that involved a four-month Martian space simulation known as FMARS, situated deep in the Canadian Arctic.

«However,» he said, «it should be noted that all female subjects in Sirius experiments were Russian, while males were Russian, German and American — so the cultural background could influence the observed differences.»

The researchers intend to continue studying communication behavior in crew members of the Sirius-21 experiment. And for both private and public agencies looking to begin extraterrestrial colonization, Shved urges that the main points revealed by his team’s analysis should ideally be discussed prior to the mission, and he stressed the importance of a good chat with «home.»

«Considering the technical means of communication, video messaging from the crew, colonists and back seems to be preferable,» he said, «as it provides better emotional connection, even under the signal lag and delay effect.»

Your Old Android Isn’t Dead. These Tweaks Can Bring It Back to Life

Clear space, optimize your battery and update the basics. These quick changes can make an old Android phone feel snappier.

You don’t need the latest Android flagship to get good performance.

Thanks to longer software support from brands like Google and Samsung, older models can still run smoothly, as long as you give them a little attention. Clearing out unused apps, updating your software and tweaking a few settings can breathe new life into a device that feels sluggish. These quick fixes can help your phone last longer and save you from spending on an early upgrade.

Before you start shopping for a replacement, try a few simple adjustments. You might be surprised by how much faster your phone feels once you free up space, optimize battery use and turn off background drains.

Whether you use a Samsung Galaxy, Motorola or OnePlus phone, chances are you can still improve battery life and overall speed without buying something new. Just remember that Android settings vary slightly from brand to brand, so the menus may look a little different depending on your phone.

Settings to improve your battery life

Living with a phone that has poor battery life can be infuriating, but there are some steps you can take to maximize each charge right from the very beginning:

1. Turn off auto screen brightness or adaptive brightness and set the brightness level slider to under 50%

The brighter your screen, the more battery power it uses.

To get to the setting, pull down the shortcut menu from the top of the screen and adjust the slider, if it’s there. Some phones may have a toggle for auto brightness in the shortcut panel; otherwise, you need to open the settings app and search for «brightness» to find the setting and turn it off.

2. Use Adaptive Battery and Battery Optimization

These features focus on learning how you use your phone, including which apps you use and when, and then optimizing the apps and the amount of battery they use.

Some Android phones have a dedicated Battery section in the Settings app, while other phones (looking at you, Samsung) bury these settings. It’s a little different for each phone. I recommend opening your settings and searching for «battery» to find the right screen. Your phone may also have an adaptive charging setting that can monitor how quickly your phone battery charges overnight to preserve its health.

Why you should use dark mode more often

Another way to improve battery life while also helping save your eyes is to use Android’s dedicated dark mode. Any Android phone running Android 10 or newer will have a dedicated dark mode option.

According to Google, dark mode not only reduces the strain that smartphone displays cause on our eyes but also improves battery life because it takes less power to display dark backgrounds on OLED displays (used in most flagship phones) than a white background.

Depending on which version of Android your phone is running, and what company made your phone, you may have to dig around the settings app to find a dark mode. If your phone runs Android 10 or newer, you’ll be able to turn on system-wide dark mode. If it runs Android 9, don’t despair. Plenty of apps have their own dark mode option in the settings that you can use, whether or not you have Android 10.

To turn it on dark mode, open the Settings app and search for Dark Mode, Dark Theme or even Night Mode (as Samsung likes to call it). I suggest using dark mode all the time, but if you’re not sure, you can always set dark mode to automatically turn on based on a schedule, say from 7 p.m. to 7 a.m. every day, or allow it to automatically switch based on your location at sunset and sunrise.

Keep your home screen free of clutter

Planning to hit up the Google Play Store for a bunch of new Android apps? Be prepared for a lot of icon clutter on your home screen, which is where shortcuts land every time you install something.

If you don’t want that, there’s a simple way out of this: Long-press on an empty area of your home screen and tap Settings. Find the option labeled something along the lines of Add icon to Home Screen or Add new apps to Home Screen and turn it off.

Presto! No more icons on the home screen when you install new apps. You can still add shortcuts by dragging an app’s icon out of the app drawer, but they won’t appear on your home screen unless you want them to.

Set up Do Not Disturb so that you can better focus

If your phone routinely spends the night on your nightstand, you probably don’t want it beeping or buzzing every time there’s a call, message or Facebook alert — especially when you’re trying to sleep. Android offers a Do Not Disturb mode that will keep the phone more or less silent during designated hours. On some phones, this is referred to as the Downtime setting or even Quiet Time.

Head to Settings > Sounds (or Notifications), then look for Do Not Disturb or a similar name. If you can’t find it, search for it using the built-in search feature in your settings.

Using the feature, you can set up a range of hours when you want to turn off the digital noise. Don’t worry, any notifications you get while Do Not Disturb is turned on will still be waiting for you when you wake up. Also, you can typically make an exception that allows repeat callers and favorite contacts’ calls to go through. Turn that on. If someone is calling you in an emergency, odds are they are going to keep trying.

Always be prepared in case you lose your phone or it’s stolen

Is there anything worse than a lost or stolen phone? Only the knowledge that you could have tracked it down if you had turned on Google’s Find My Device feature.

To prepare for a successful recovery, here’s what you need to do: Open the Settings app and then search for Find My Device. It’s usually in the Security section of the Settings app.

If you have a Samsung device, you can use Samsung’s Find My Mobile service, which is found in Settings > Biometrics and security > Find My Mobile.

Once that’s enabled, you can head to android.com/find from any PC or mobile device and sign in to your account. Samsung users can visit findmymobile.samsung.com to find a lost phone.

If you have trouble setting any of this up, be sure to read our complete guide to finding a lost Android phone.

Assuming your phone is on and online, you should be able to see its location on a map. From there, you can make it ring, lock it, set a lock screen note to tell whoever has it how to get it back to you, or, worst-case scenario, remotely wipe the whole thing.

And always keep your phone up to date

As obvious as it may seem, a simple software update could fix bugs and other issues slowing down your Android device.

Before you download and install the latest software update, make sure your device is connected to Wi-Fi, or else this won’t work.

Now, open the Settings application and type in Update. You’ll then either see Software update or System update — choose either one. Then just download the software, wait for a few minutes and install it when it’s ready. Your Android device will reboot and install the latest software update available.

There’s a lot more to learn about a new phone. Here are the best ways to boost your cell signal, and here’s a flagship phone head-to-head comparison. Plus, check out CNET’s list of the best cases for your Samsung phone. More of an Apple fan? We have tips for boosting your iPhone’s performance, too.

Your Pixel 10 Might Have Issues With Older Wireless Chargers

You might want to try taking the case off your phone in order to successfully charge it.

When Google introduced the Pixel 10 lineup in August, it became one of the first major Android phones to receive the Qi 2 wireless charging standard, which Google calls Pixelsnap. However, users noticed issues with wireless charging on the Pixel 10 almost immediately after its release.

Some people are having trouble charging their phone with the new Pixelsnap charger, and others are having issues with older wireless chargers, including Google’s own Pixel Stands. The bulk of the problems happen when a case is on the phone — whether it has the magnet array or not.

I own both the first and second generation Pixel Stands and both will charge my Pixel 10 Pro XL without an issue if there’s no case on it. However, when I add a case to my phone, the problems begin.

I have three cases for my phone, the Mous Super Thin Clear Case, the Magnetic Slim Case Fit by Grecazo, and a no-name soft TPU case. If my phone has any of those cases on and I attempt to charge it while it’s vertical, it starts to charge and then stops after a second or two, and keeps doing that.

I can fix this for the first-generation Pixel Stand by turning the phone horizontal, but it will still charge very slowly. I can’t seem to fix it at all for the Pixel Stand 2 — vertical, horizontal, it doesn’t charge.

Not everyone has this issue

The problem doesn’t seem to be universal. CNET editor Patrick Holland said he had no issues charging the Pixel 10 Pro during his time with it.

A Google spokesperson told me the Pixel 10 lineup is not optimized for older Qi wireless charging standards, but that doesn’t necessarily mean the phones won’t work with older wireless chargers.

Qi 2 is backwards-compatible with older standards, but the phone’s height and charging coil placement on both the phone and the charger are still factors. If you’re having problems, you might see if removing the case helps.

The prospect of potentially needing to replace your older wireless chargers with newer ones isn’t ideal, especially if you shelled out $80 for one or both of Google’s own Pixel Stands. Still, if you want the best wireless charging speed for your brand new Pixel 10 phone, it won’t be with wireless chargers that only support older Qi standards.
