15 Ways the International Space Station is Benefiting Earth  With astronauts living and working aboard the International Space Station, NASA is learning a great deal about creating and testing critical systems, maintaining efficient communications and protecting the human body during a deep space mission. While these are critical to our journey to Mars, it is important to also note all the ways in which research conducted and technology tested aboard the orbiting laboratory help us here on Earth.   Here are 15 ways the space station is benefiting life on Earth:   i.

What you need to know about life on the International Space Station blogger-avatar by Mariella Moon In an unfortunate turn of events, Orbital Sciences' Antares rocket exploded a few seconds after launch last week. The rocket was thankfully unmanned, but it was intended to ferry critical supplies to astronauts and cosmonauts aboard the International Space Station. Luckily, crew members currently aboard the space station have enough food to last until March 2015 -- more than enough, as some are scheduled to come home this month. People living on the ISS depend on the ground crew for most of their needs, and each resupply mission brings spare parts and hardware needed for repairs and experiments, packaged food and hygiene supplies. These hygiene amenities and prepackaged chow differ quite a bit from what we typically use: The shampoo and hand soap, for instance, are the special no-rinse kind, while some of the food comes in dehydrated powder form.

The human heart is an organ that pumps blood to be circulated throughout the body. It supplies oxygen and nutrients to the tissues and removes carbon dioxide and other wastes. It does this twenty four hours, seven days a week.

ANATOMY OF THE HEART In humans, the heart is roughly the size of a large fist and weighs between about 10 to 12 ounces (280 to 340 grams) in men and 8 to 10 ounces (230 to 280 grams) in women, according to Henry Gray's "Anatomy of the Human Body." The human heart has four chambers: two upper chambers (the atria) and two lower ones (the ventricles), according to the National Institutes of Health.

Maybe you like to share a bottle of wine with your girlfriends along with some laughs. It's a daily or weekly habit and it's harmless. Or is it? The frightening thing about alcohol is how quickly one can build up a tolerance to it. Suddenly, a nightly beer no longer relaxes you - it now takes three or four. Maybe you find yourself ordering another bottle of wine because the first just went too quickly.
