Bone mineralization is actually one of those lack-of-gravity problems. For each month in space, Logan says the human body loses 1 percent of its bone mass. in addition to also, once back on Earth, the bones don’t grow back.
“I’m not trying to throw cold water on the idea of going to Mars. I want to make sure we can survive if we do go,” Logan said.
He says, if putting humans on Mars is actually truly a near-term goal, This particular means studies today must focus on Martian gravity, or 0.38 Gs.
“If we study the effect of 0.38 on the body around the clock, in addition to also This particular doesn’t work, you can cross off Mars as a human settlement site until we do sort out the medical diagnosis,” Logan said.
After medically serving 25 space shuttle missions, Logan stated current measures are stop-gaps in which do little to actually counteract the effects of weightlessness on the body.
For “each deleterious effect,” Logan says there’s a brand new mechanical or pharmaceutical countermeasure in which only “retards the deconditioning. They don’t neutralize This particular in addition to also they don’t reduce This particular,” Logan said.
“We need to start sending more people into space if we’re actually going to get somewhere, with even problems we know like the gravity prescription,” he added.
The scientist also said in which This particular is actually critical to use the words “outpost” in addition to also “settlement” distinctly when talking about space exploration.
“Let’s stop playing fast in addition to also loose with This particular idea in which the ISS [International Space Station] is actually our first settlement in space. We have a permanent presence, yet with rotating crews,” Logan added. “Settlement is actually men, women, children, over multiple generations.”
