*Scientists have endless ideas for extraterrestrial exploration. Some are feasible, some not. In a two-part series, we look at how UA engineer Roberto Furfaro gives the red or green light to space missions. First, searching for Delta-V, the complex factor that makes a space mission viable.*

Our solar system is becoming a familiar backyard, thanks to the University of Arizona’s Lunar and Planetary Laboratory, or LPL, a world leader in interplanetary exploration.

LPL’s Phoenix Mission to Mars scooped up the first evidence of water-ice on the Red Planet, and its HiRISE camera continues to beam stunning images of the Martian landscape back to Earth. (more…)

NASA Spacecraft Data Suggest Water Flowing on Mars

PASADENA, Calif. –– Observations from NASA’s Mars Reconnaissance Orbiter have revealed possible flowing water during the warmest months on Mars.

“NASA’s Mars Exploration Program keeps bringing us closer to determining whether the Red Planet could harbor life in some form,” NASA Administrator Charles Bolden said, “and it reaffirms Mars as an important future destination for human exploration.” (more…)

*Mars developed far more quickly than our blue planet*

Mars developed in as little as two to four million years after the birth of the solar system, far more quickly than Earth, according to results of a new study published in this week’s issue of the journal Nature.

The red planet’s rapid formation helps explain why it is so small, say the study’s co-authors, Nicolas Dauphas at the University of Chicago and Ali Pourmand at the University of Miami. (more…)

NASA Orbiter Reveals Big Changes in Mars’ Atmosphere

PASADENA, Calif. — NASA’s Mars Reconnaissance Orbiter has discovered the total amount of atmosphere on Mars changes dramatically as the tilt of the planet’s axis varies. This process can affect the stability of liquid water, if it exists on the Martian surface, and increase the frequency and severity of Martian dust storms.

Researchers using the orbiter’s ground-penetrating radar identified a large, buried deposit of frozen carbon dioxide, or dry ice, at the Red Planet’s south pole. The scientists suspect that much of this carbon dioxide enters the planet’s atmosphere and swells the atmosphere’s mass when Mars’ tilt increases. The findings are published in this week’s issue of the journal Science. (more…)
