NASA Continues Fight Against Bone Mass Loss

 NASA Continues Fight Against Bone Mass Loss

As you probably know, one of the problems with humans entering into weightless environments is that we've spent a heck of a lot of time evolving to do just fine WITH the force of gravity holding us down. Take that away from us and a host of things start to go haywire in our gravity-based bodies. Chief among these is bone mass loss. Quite simply, if you don't use it, you lose it -- and at an incredible pace. In fact, visitors to the International Space Station lose up to 10 times more bone mass each month than most postmenopausal women do on Earth do in the same time frame.* NASA has tried to address this issue in the past by having astronauts use treadmills, but according to a recent Science Daily article, the agency figured out a promising way to improve on the measure.

 NASA Set to Check Out Your Carbon Footprint

In 4 days, 17 hours and a handful of minutes, NASA's Orbiting Carbon Observatory will get serious about monitoring the Earth's carbon dioxide sources and sinks. The observatory is already on-site at Vandenberg Air Force Base in California, waiting for its impending launch (and delay and rescheduled launch date) and eventual moment in the climate change spotlight.
