Extract a finite length of space; divide it into halves, then into quarters, then into eighths…… After infinite number of divisions, what will remain? A tiny “space atom” that has an infinitesimal, albeit finite length? Absurd, for an infinite number of finite lengths adds up to an infinite length. A “space point” that has no [...]

FOR THE 10TH CONSECUTIVE YEAR, University of Wisconsin-Madison students have found themselves floating upside down over the Gulf of Mexico.

Seven students from the UW-Madison ZeroG team spent a week in April at the NASA Johnson Space Center in Houston, Texas. The team participated in the annual NASA Reduced Gravity Student Program, which allows students to propose, design and test an experiment of their choice in varying gravity conditions.

The results from the UW-Madison experiment show a particular spray cooling method is not dependent on gravity—a significant finding that means spray cooling could be used in airplane and other high-heat electronics.

Lunar dust is sharp stuff. Created when micro-meteorites hit the moon’s surface and shatter into razor-blade-like bits of melted glass, the abrasive dust can cause a multitude of problems for astronauts and machinery.
Within a decade, NASA plans to begin building a permanent lunar colony to serve as an outpost en route to Mars.
So, the [...]
