Testing Hardware for Growing Plants and Vegetables in Space

Testing Hardware for Growing Plants and Vegetables in Space Astronauts on the International Space Station continue testing the VEGGIE hardware for growing vegetables and plants in space. VEGGIE provides lighting and nutrient supply for plants in the form of a low-cost growth chamber and planting „pillows“ — helping provide nutrients for the root system. via NASA http://ift.tt/1E8ffZG

This photograph of NASA astronaut Serena Aunon (@AstroSerena) moving tools and equipment underwater was taken during the NASA Extreme Environment Mission Operations (NEEMO) 20 mission. NEEMO 20 is focusing on evaluating tools and techniques being tested for future spacewalks on a variety of surfaces and gravity levels. via NASA http://ift.tt/1I7kFb3

Frosty Gullies on the Northern Plains of Mars

Seasonal frost commonly forms at middle and high latitudes on Mars, much like winter snow on Earth. However, on Mars most frost is carbon dioxide (dry ice) rather than water ice. This frost appears to cause surface activity, including flows in gullies. via NASA http://ift.tt/1LZCz3H
