A 59-year-old Russian cosmonaut has become the first person to spend 1,000 days in space. Russian space agency Roscosmos said Wednesday that Oleg Kononenko achieved the cumulative space time record having made five journeys to the International Space Station dating back to 2008.
I assumed it meant consecutive days and I was pumping my fist as I figured that if any space agency would sacrifice an astronaut to find out how long it takes for zero G to kill, or permanently compromise their health, well, it would be Roscosmos...
Still, very impressive.
Edit: Not because I want this guy to die, but because I'm really curious about the hard health limits of zero g living.
Micro-gravity also allows for biological experiments that are too costly or complex to achieve planetside. So not only is he testing protocols and treatments for long-term space travel, but he's working towards therapies and treatments which become available to the earthbound.
