A Mars simulation crew spent 520 days in confinement. Here are their tips

If you’re struggling in quarantine right now, you might look for advice from someone how has survived a truly extreme confinement situation, such as an astronaut who was part of the European Space Agency (ESA)’s Mars500 simulation study.

Simulation missions are psychological experiments to learn about how humans fare in the space environment, without actually sending anyone to space. Especially for missions to Mars, which will require long travel times, a crew will have to work together in difficult circumstances for over a year, with little chance to get away from each other or from their tasks.

The Mars500 simulation mission, which began in 2007, was one of the best-known and longest-running simulation studies, including three different crews of volunteers. It culminated with a 520-day mission featuring a crew of six men from Russia, France, Italy, and China. They spent their time in a simulated spacecraft and had to get by without sunlight, fresh food, or fresh air. So they learned a thing or two about working in isolation, as did the scientists studying them.

It is one of these crew members, French engineer Romain Charles, who appears in ESA’s video with tips on surviving confinement. He gave nine tips for staying sane in difficult environments:

  1. Remember that the situation is temporary. Things that you want to do right now but can’t, you may well be able to do later.
  2. Stay busy. It’s easy to get bored and lethargic in confinement, so keep yourself busy with reading, music, and other hobbies. Charles did things like improving his Russian with his Russian crewmates, and getting his Chinese crewmate to teach him calligraphy.
  3. Live in the present. Taking one day at a time feels more manageable than thinking about the long term confinement.
  4. Keep a regular cycle of day and night. Humans respond very well to regular sleep cycles, and very poorly to interrupted cycles. Try to wake up and go to bed at the same time every day.
  5. Be creative. Break the monotony by trying new things and having fun. Charles has delightful photos of the many different and increasingly ridiculous styles of beard he tried during his confinement.
  6. Stay in touch. You’ll feel much better if you have regular contact with family and friends.
  7. Spend energy. You need to burn off all that excess energy through exercise and activity.
  8. Communicate. When you’re in an enclosed space with others, it’s easy to let tensions boil over. Communicate about your needs.
  9. Look for unexpected rewards. Charles describes the absolute joy he experienced when he ate fresh food for the first time after confinement. Things that he had taken for granted became incredibly precious to him.

Charles isn’t the only astronaut to have shared advice on this topic. Canadian astronaut Chris Hadfield also shared his tips recently.

Microsoft just discovered the next big evolution in displays
Resident Evil 4 running on the LG UltraGear 45 gaming monitor.

Microsoft is working on a new patent that aims to bring unprecedented levels of control to displays. The new tech, dubbed Pixel Luminesce for Digital Display, allows you to micromanage every single pixel of your display, adjusting the brightness as needed. If and when this makes it out of the development stage, it could end up being huge for all sorts of use cases, and could bring major improvements to some of the best gaming monitors.

The patent application describing the tech, first shared by Windows Report, describes the new technology as something that would enable selective dimming. With Microsoft's new tech, you could decide that one part of the display stays brighter while the rest of it remains unaffected, and this would happen dynamically.

Microsoft Edge is slowly becoming the go-to browser for PC gamers
microsoft edge chromium to roll out automatically soon chrome

Microsoft Edge is already jam-packed with features that other web browsers don't have, but a new one might well help your PC run faster while gaming. The default Windows web browser now has the option to limit the amount of RAM it uses, helping you prioritize RAM access to other applications or games. The feature is currently being tested in the Canary version of Microsoft Edge and could roll out to everyone if Microsoft deems it useful enough and gets quality feedback.

Spotted by X (formerly Twitter) user Leopeva64, the setting for this new feature is buried in the System and Performance section of the latest Canary version of Microsoft Edge. It is being rolled out gradually, so not everyone has it yet, but it gives two options for controlling your PC resources.
