In two new papers published in Mars, The International Journal of Mars Science and Exploration (The Mars Journal), Donald Rapp reviews the current state of our understanding of life support and radiation safety for human missions to Mars.

In "Mars life support systems", he concludes that current plans for life support for human missions contain optimistic assumptions regarding the degree of recycling and reliability that can be achieved, and the amount of mass that life support systems may require.

In "Radiation effects and shielding requirements in human missions to the moon and Mars", he compares and contrasts the levels of radiation shielding required for human missions to the moon and Mars and finds that currently planned missions to both bodies are not without potentially serious radiation risks.

The Mars Journal is a peer reviewed open access journal focused on Mars science, exploration and policy.

NASA Spots Opportunity In Stunning MRO Image Of Victoria Crater

Pasanea CA (JPL) Oct 06, 2006
NASA's long-lived robotic rover Opportunity is beginning to explore layered rocks in cliffs ringing the massive Victoria crater on Mars. While Opportunity spent its first week at the crater, NASA's newest eye in the Martian sky photographed the rover and its surroundings from above. The level of detail in the photo from the high-resolution camera on the Mars Reconnaissance Orbiter will help guide the rover's exploration of Victoria.
