Off-world colony simulation reveals changes in human communication over time with Earth

Elton John famously sang that Mars "ain't the kind of place to raise your kids", but one day space agencies across the globe hope to prove him wrong by seeing the first human set foot on the Red Planet, and potentially colonizing it or any other moon or planet.
However, those who make the journey will not only have to survive on a freezing planet with no breathable atmosphere, but live in isolation unlike any other explorers in human history.
At its closest proximity, Mars is still almost 55m km away from Earth, making communication delays and supply issues between the two worlds unavoidable. This requires crew members to effectively cope with stressful conditions by themselves, with limited autonomous resources available on board.
With little chance of conducting a trial run in space, scientists have resorted to terrestrial experiments to see how astronauts cope with such challenges. A previous isolation experiment called Mars-500 revealed a psychological detachment from mission control among those who took part, raising fears that it could lead to resistance from future crews in deep space to any commands.
Satellites pinpoint communities at risk of permafrost thaw

Thawing permafrost in the Arctic is already unleashing methane and carbon dioxide to the atmosphere, exacerbating global temperature rise. As well adding to the climate crisis, this ground, which has been frozen for thousands of years, is becoming unstable and causing serious issues for local communities. For the first time, data from the Copernicus Sentinel-1 and Sentinel-2 missions along with artificial intelligence have been used to offer a complete overview of the Arctic to identify communities and infrastructure that will be at risk over the next 30 years.

Virgin Galactic has sold around 100 tickets since flying its founder Richard Branson to space last summer, with commercial services expected to begin by the end of 2022, the company said in its financial results Monday.
The current price of the fare is $450,000 per seat, well above the $200,000-$250,000 paid by some 600 customers from 2005 to 2014.

China launched its Shijian 21 satellite into orbit from Xichang late in October on a mission to "test and verify space debris mitigation technologies". However, the launch triggered fears in the US military that Beijing had unveiled a new "satellite-crushing" weapon to achieve superior space attack systems.
