Remarkably, on average, one Martian meteorite lands on Earth each month. But finding these scientific treasures is not a job for a human, at least according to the Nomad robot - this week's entry in the Extreme Explorers Hall of Fame. The timing of the selection corresponds to a new Science study trying to resolve the paradox: Why does Earth get such valuable samples, when Mars isn't hit that often by large rocks?

Extreme Explorers' Hall of Fame (a weekly series) will show you the best explorers of extreme environments; these machines, rovers, submersibles and crawlers all aim to traverse the toughest terrain. Their balance swings between an engineer's precision and a scientist's bold curiousity. The limits of weight, power, communication, and hazard prediction all will grade the hall of fame entries. The series will explore the factors required to make a planet, a nuclear reactor or a volcano survivable as astrobiology explorers probe the question of whether biology can flourish in the most unlikely places on earth or beyond. Meet the Mars explorer test unit: FIDO.

The light from a massive explosion 2 billion years ago just arrived March 29th on Earth, thus setting off a global flurry of robotic telescopes to track what turned out to be 100 times more intense than any previously studied supernova events.

The Martian Chronicles, a multipart series, show the inside story of what it is like to join in a four-year space mission, in preparation for the dramatic landing sequence planned for January 2004. From the science diaries of Cornell's Steve Squyres, the principal investigator for the Mars Exploration Rovers' science package, this first-hand account shows exactly what it takes to plan and build a mission to another planet.

Never previously in modern human history has Mars been as bright or as close to Earth as tonight. Look for it in the night sky, as it will be easily recognized by its red tinge. As with all planets, its light will also stand out from the background of stars, because it will not appear to flicker, but instead looks like a steady, bright object. An amateur's four-inch telescope may reveal the polar cap and some surface features.

The Mars Exploration Rovers provide geologists with their first chance to do field work on Mars, so the rovers took along the space version of a common geologist's tool, the pocket magnifying glass or hand lens.
