Plans to launch 50,000 satellite mirrors into space could lead to ‘planetary scale' disruption of our sleep and ecosystems, according to scientists.

Life in space is weirder than you might think, with the crew facing toilet issues, saliva collections, DIY fixes to onboard components and a menu of dehydrated food.

Scientists around the world are sounding the alarm over an ambitious plan to install thousands of mirrors and myriad satellites in space, claiming that it will impact sleep and various ecosystems on a global level.

The experts warned the Federal Communications Commission (FCC), which regulates satellites and space policy, that altering the natural rhythm of light and dark could have untold consequences on biological clocks that regulate sleep, and hormone secretion in humans and animals.

Russian astronaut Vasily Tsibliyev hadn’t had a good night’s sleep for 12 days. He was being kept awake on purpose, as part of a study about sleeping on board the space station Mir. On the 13th day, June 25, 1997, he was assigned to guide a cargo ship ...

Researchers said in a study that even small increases in the brightness of the night sky can affect human sleeping rhythms. Massive reflective satellites would bring in sources of light that are continuously operational even after the sun sets in large geographical regions.

Sleep deficiency is pervasive among astronauts before and during space flight, and the reported incidence of sleep-promoting medication use is 20 times greater than the proportion of Americans estimated to use hypnotic drugs at any time in a given year ...
