With binoculars, examine the rugged face of the Moon. It is pocked with thousands of impact craters from interplanetary asteroids and comets. Ever wonder why Earth, a much bigger target, apparently has so few craters? Did Earth just get lucky? No!

NASA is returning to the Moon, but first NASA engineers would like to test designs for lunar landers and rovers on genuine lunar soil. Just one problem: There's not enough real moondust to go around. So scientists are making some "true fakes."

A Japanese spacecraft that landed on an asteroid found a ball of rubble held loosely together by its own gravity, unlike other asteroids that have been visited, according to reports from the mission published on Thursday.

An early, persistent problem noted by Apollo astronauts on the Moon was dust. It got everywhere, including into their lungs. Oddly enough, that may be where future Moon explorers get their next breath of air.

A team of NASA scientists has used a bit of intellectual judo to figure out a way to take advantage of Moon dust grains' electrostatic charge to repel them. In fact, they've come up with a new application of an old idea.

For the first time in the history of planetary exploration, the MARSIS radar on board ESA's Mars Express has provided direct information about the deep subsurface of Mars.

Scientists and engineers figuring out how to return astronauts to the moon, set up habitats, and mine lunar soil to produce anything from building materials to rocket fuels have been scratching their heads over what to do about moondust. It's everywhere!

A large team of NASA scientists, led by earth and planetary scientists at Washington University in St. Louis details the first solid set of evidence for water having existed on Mars at the Gusev crater, exploration site of the rover Spirit.

NASA has a new Vision for Space Exploration: in the decades ahead, humans will land on Mars and explore the red planet. Brief visits will lead to longer stays and, maybe one day, to colonies. First, though, we're returning to the Moon. Why the Moon before Mars? NASA scientists give their reasons.

Driving, digging, mining: these are things astronauts will be doing one day in the sands of Mars. It's not as simple as it sounds. Understanding granular physics is essential for designing industrial machinery to handle vast quantities of small solids -- like fine Martian sand.

Word of the Day
  • Growing in low tufty patches.
The word 'cespitose' comes from a Latin word meaning 'turf'.
