polar bears

Dr. Pascal Lee can call
himself a rocket scientist without cracking a smile.
A researcher with the U.S.
National Aeronautics and Space Administration, Pascal is also a certified Mars
nut.
And thats whats
brought him up to Devon Island each year for the last decade, joined by other
scientists and space enthusiasts who clamber around the Haughton Crater.
From July 4 to August 9,
a crew of about 55 scientists and support staff with the Haughton-Mars Project
will camp at the inhospitable swath of polar desert, chosen because it resembles
the landscape of the Red Planet.
Well, except for the polar
bears, which foiled efforts this winter to grow lettuce inside the automated
Arthur C. Clarke Greenhouse named after the famed author of 2001:
A Space Odyssey, and funded by the Canadian Space Agency.
The greenhouse is rigged
with gadgets that monitor and water the plants mostly lettuce, with basil,
radish and zucchini automatically.
The greenhouse this
past winter was visited by polar bears, Lee said as he prepared to board
a flight from Iqaluit to Resolute Bay last Thursday. They knocked a big
hole in the side of it.
This season theyll
give robotic gardening another try, along with other experiments.

The summer camp receives
support from NASA, the Canadian Space Institute, the Mars Institute, and SETI,
the Search for Extraterrestrial Life Institute.
Most years these scientists
are accompanied by a gaggle of wannabe Mars explorers who spend a month poking
around the crater in sim that is, pretending theyre
actually on Mars, dressed in space suits and driving souped-up ATVs.
But this year the Mars
Society voted against sending their entourage to Devon Island, because they
hope to save up cash for an unprecedented four-month expedition next year.
For scientists such as
Lee, this summer will be a busy one, wrapping up old experiments and beginning
new tests.
They will continue testing
an automated drill used to collect rock and soil samples up to five meters below
the surface, provided by NASA, for the third and final year.
Drilling is a hands-on
type of activity for humans, Lee said. Were training a robot
to do that a robotic mind.
Other tests will focus
on the people, not the landscape.
The saliva of participants
will be collected and analyzed to look for tell-tale enzymes produced under
stressful conditions to better understand how the group copes under the pressures
of a tight schedule.
And theyll practice
the medical evacuation of an injured astronaut, under the watch of the Mars
Institute, the NASA Johnson Space Center in Houston, Texas, and the Canadian
Space Institute.
The scenario: three spacemen
are hiking on the moon when one trips, hurts himself, and is unable to walk.
How prepared you
are for an injury can make or break a mission, Lee said.
A rescue will be performed
with hand winches and a special litter designed to roll over rock and ice, molded
to hold a space suit. The injured spaceman will then be loaded onto the MARS-1
Humvee.
Meanwhile, the vitals of
the injured man will be watched from the International Space University in Strasbourg,
France, where a summer space program is held.
The whole thing will
be played out live in France, he said. His heart rate will be pulsing
in Strasbourg on a screen.
Their decade of research
has also taught them a thing or two about the crater itself.
For instance, last year
a study showed the Haughton crater is in fact 38 million years old rather
than 23 million years old, as previously imagined.
And while giant meteors
crashing into the planets surface are generally seen as bad for evolved
creatures, such as humans, these cataclysmic impacts could actually be good
for smaller, less-evolved life.
Microbes have been found
to thrive in the warmth and shelter found in broken rocks and thermal vents.
In fact, Lee said craters could be central to the origins of life
on Earth.
He also said research on
Devon Island could challenge the belief that Mars was once far warmer. The Haughton
Crater shows similar thaw and melt patterns as found on Mars can be created
in a cold climate, Lee said.
The wide range of
what we see on Mars, we can see on Devon, he said.
But why explore Mars? Lee
said one answer is such an expedition could answer important questions about
whether life exists on Mars, which in turn could tell us about the origins of
life on Earth.
Could we be related
to life on Mars? These are not just philosophical questions. These are scientific
questions, Lee said.
Not only that. Space exploration
could even bring peace on Earth, Lee suggests.
It will stabilize
our relationships on Earth by being involved in a big joint venture, he
said.
The spacey gadgets used
on the crater may not seem of immediate importance to many earth-dwellers, other
than deadbeat gardeners, but Lee points to a host of inventions produced by
the space program.
Take telephone calls and
weather forecasts in the North, which both depend on satellites orbiting the
Earth to relay information.
The same goes for satellite
television, and the sensors used inside digital cameras.
Lee sees a Mars in the
future that resembles Antartica, with research stations manned by humans.
We think its
eminently feasible to send people to Mars. We just need to do it right,
he said.
But that doesnt mean
he always sees eye-to-eye with other Mars enthusiasts.
Lee was involved with the
founding of the Mars Institute, although hes no longer affiliated with
it. He says he disagrees with plans to abandon Earth for another planet as unrealistic.
We need to think
beyond the romance, he said.
The earth is an exceptional
oasis, he said. It needs to be understood and protected, not fled.
