The spectacular journey of the Jupiter-orbiting spacecraft, Galileo, ended by crashing into the giant planet's atmosphere. Partly because of its successful mapping of Europa's probable frozen ocean, Galileo couldn't be left unattended to, or it might risk contamination of one of our solar system's most intriguing prospects for habitability.

To the Mars Exploration Rover mission, water, past or present, is the grail. One way to look for past water is to analyze soil and rock surfaces for evidence of iron-containing minerals (or compounds), which differ depending on whether the environment in the past was wet or dry. Such mineralogical analysis is the purpose of an instrument called the Mössbauer spectrometer.

As NASA successfully launched their Mars' probe called Spirit, its seven-month journey echoes back to the pioneering effort of the earliest explorers. Take a retrospective look at the twin Viking landers, and how the key decisions were made by those who were in the room at the Jet Propulsion Lab in 1976. In their own words, revisit the story behind the first lander to orbit another planet, and a science mission that returned data to Earth for seven years after its touchdown.

By watching the tidal pull on their orbitting Global Surveyor spacecraft, scientists have confirmed that Mars has a liquid iron core, much like Earth and Venus. Many astrobiologists conclude that such a molten and magnetic interior is critical to developing life.

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?
