After six months of testing and very careful calibration, the European Space Agency’s GOCE satellite is sending back its first data sets as it now begins precisely mapping tiny variations in Earth’s magnetic field. How does one go about mapping the Earth’s fundamental force? As it turns out, very, very carefully.

As planets of our solar system tug at each other with their gravitation tethers, they create a protean sea of forces and counter forces. But within that maelstrom lay gravitational channels that could serve as highways for future spacecraft, just as soon as Professor Shane Ross of from Virginia Tech University finishes mapping them out.

Scientists working on behalf of NASA have successfully levitated a mouse using a strong magnetic field. I pay taxes so that stuff like this can happen. I don't hate animals. It's for understanding microgravity better, ok?

NASA astronauts Edward Lu and Stanley Love first proposed using a robotic spacecraft to nudge space rocks away from Earth using the gentle force of gravity a few years ago. Now a European aerospace giant has begun seriously investigating the concept.

Not inclined to wait for a suborbital ride on Virgin Galactic, Noah Fulmor and Erin Finnegan became the firt couple to be wed in microgravity this past weekend over the skies of south Florida.

Doesn’t it seem that all movies and television shows suggest that space will one day be populated by nothing but dashingly lithe men and buxom women? Well there’s a reason it’s called science fiction, because extended space travel could actually leave astronauts a gross, bloated, unattractive mess. Astrobiologist Dr Lewis Dartnel projects that long-term exposure to zero gravity has the potential to ravage your looks in the most unappealing ways.

When humans eventually live on the moon and Mars, the discomforts of eating freeze-dried food and drinking our own urine will hardly be our only space nuisances. Apparently, our feet will tingle, we'll get headaches and toothaches, our eyes will be runny, and we'll have chronically stuffy noses.

Scientists have a pretty good notion of what will happen to your body when you're walking on the moon or traveling gravity-free for two years en route to Mars -- thanks to a cadre of bed-ridden test subjects.

Using an unbelievably powerful laser over an unbelievably short period of time, scientists have been able to alter the surface of metals to control the flow of water across their surfaces down to the individual molecule.

And when we say an unbelievable amount of energy, we’re talking about the power of the entire grid of the United States at once. When we say an unbelievably short period of time, we’re talking about a femtosecond, which is to a second what a second is to 32 million years. Think about both of those for a femtosecond.
