Understanding how much water was on Mars in the past is crucial to knowing its potential habitability. We know that on Earth, nearly anywhere we find water we find life. So if Mars was once a lot wetter than it is today, the chances of habitability increase considerably. We have found ev...
"Water is key because almost everywhere we find water on Earth we find life," NASA's web site points out. "If Mars once had liquid water, or still does today, it's compelling to ask whether any microscopic life forms could have developed on its surface." The first missions to Mars ...

When measured from its base, deep in the ocean, Mauna Loa is the second largest mountain in our solar system, after the one on Mars. Kim Binsted says this experiment looks at how the volunteers interact, or get along with each other. “We study how well they work together, how we ...
With more than 4,000 exoplanets—planets orbiting stars other than our sun—discovered so far, it may seem like we are on the cusp of finding out whether we are alone in the universe. Sadly though, we don't know much about these planets—in most cases ju
is that exactly like on Mars three and a half billion years ago, the climate is changing very fast, and water and ice are disappearing. But we need to go back to that time when everything changed on Mars, and to do that, we need to go higher. Why is that?...
Humans have long had a fascination with Mars, and NASA has ambitious plans to send astronauts there within the next few decades. Anyone walking on Mars would likely explore only a small fraction of the planet's surface. But without oceans or other bodies of water, could an astronaut walk ...
On their sixth album, the Jonas Brothers celebrate the music, people, places and sounds that helped them reach their full potential — and create the music they've always been destined to make.
fall of 2014, and while its entry on Certain Glass Wool Fibers (Inhalable) states that they are “reasonably anticipated to be human carcinogens,” it also goes on to say that there is so much variation in production that full assessments must be made on a case-by-case basis [source: ...
Space farming studies the effects of microgravity on plant growth, focusing on how plants orient roots and stems with reduced gravity, which is crucial for potential farming on the moon or Mars. In space, efficient use of energy is vital, so researchers use light-emitting diodes (LEDs) to mi...
