BY DIANA WHITMAN BY MICHAEL MEYER, NASA HEADQUARTERS NASA, Pat Rawlings MODULESa MARS ON The theme of this issue of Ad Astra is “Mars on Earth” — how we can use our planet to get ready to explore Mars. Even though a human to Mars has not been formally EARTH started, people all over the world are preparing for the day when humans will live and work on Mars. Many locations on Earth have characteristics that make them similar to Mars—such locations are referred to as “Mars analogs.” It is in these locations where a wide variety of research projects are underway. There is one substance whose abundance on Mars is crucial if life ever took hold Keith Cowing on this world. Water. The abundance of water will also be a key driver in how humans Guest Editor explore Mars. In “Houston, we’ve got water!” former NSS Executive Director Pat Dasch provides an overview of a recent scientific meeting where the initial results from the Mars Odyssey spacecraft were presented. The preliminary news is promising: it would seem that Mars has a lot of water— and it is everywhere and within easy reach. Despite having a large amount of water, Mars is still an incredibly dry place at the surface. One of the Mars analogs being studied for its potential to help us understand the challenges life might face is the ultra- dry Atacama Desert in South America. In “Two dry for life: The Atacama Desert & Mars,” NASA’s Christopher McKay provides an overview of current research as it relates to the search for life on Mars. One of the planned steps in the current robotic exploration of Mars is to return samples to Earth for analysis. This will be a complex and costly mission to undertake. Luckily, nature is way ahead of us and has been throwing rocks from Mars to Earth since the dawn of the solar system. In “Hitchhiking on a Meteorite: Is there Mars Life on Earth?,” I look at how rocks are thrown between worlds—and what the prospects are for life to have made the trip as well. Getting to Mars may be hard, but unraveling the planet’s history will be an equally arduous task. Life, if it is present, may be located in rather hard to reach locations. As such, new technologies need to be devel- oped to conduct this search. In “Astrobiology on Mars: under pressure and in hot water,” NASA’s Michael Meyers provides an introduction to the challenges and possible solutions. Sending humans to Mars in such fashion that they can make the best of the opportunity in a safe and productive way is going to require that we do a lot of homework first on Earth. It is one thing to test a piece of hardware or a procedure in the comfort of a lab. It is quite another thing to do this in a hostile, expeditionary environment—one which also resembles the harsh conditions on Mars. In “Mars on Earth: The NASA Haughton-Mars Project,” the SETI Institute’s Pascal Lee looks at the wide range of Mars ana- log research being performed at Haughton Crater located on Canada’s remote Devon Island. Many Mars mission scenarios include life support systems composed of a mixture of chemical and bio- logical components. In “Earth on Mars: Greenhouses on the Red Planet,” I examine what it would take to build a greenhouse on Mars—and how we might decide some day to make the entire planet habitable through terraforming.
