How will astronauts get the nutrition they need on a journey to Mars?

To help assess the impact spaceflight has on nutrition, astronauts provide blood and urine samples before, during and after their space missions. A biochemical profile is created for each astronaut. The ultimate goal is to keep astronauts healthy. As mission durations increase and as we prepare for our journey to Mars, it is important to understand how the human body changes with longer exposures to microgravity and higher radiation doses.

4,000 Kilometers Above Saturn's Iapetus...
What does the surface of Saturn's mysterious moon Iapetus look like? To help find out, the robotic Cassini spacecraft now orbiting Saturn was sent soaring last week just 2,000 kilometers from the unique equatorial ridge of the unusual walnut-shaped two-toned moon. The above image from Cassini is from about 4,000 kilometers out and allows objects under 100-meters across to be resolved. Cassini found an ancient and battered landscape of craters, sloping hills, and mountains as high as 10 kilometers and so rival the 8.8-kilometer height of Mt. Everest on Earth. Just above the center of this image is a small bright patch where an impacting rock might have uncovered deep clean water ice. Space scientists will be studying flyby images like this for clues to the origin of Iapetus' unusual shape and coloring with particular emphasis because no more close flybys of the enigmatic world are planned.

President Obama’s is intended as a commitment to reducing our carbon emissions and making a better future for the next generation. However, the President and the EPA still rely on fracked natural gas and cap-and-trade schemes as a part of their vision – neither of which will help the planet.
