Mars,
the red planet, these are the journeys of the rovers Spirit and Opportunity,
their five year missions to explore strange new surfaces, to seek out new water
evidence and new signs of life, to boldly roll where no rovers have gone before...
The trek of
NASA's
Mars Exploration Rovers across the fourth planet from the Sun is the focus
of "Five Years on Mars," a new one-hour special airing on the National
Geographic Channel on Sunday. The show, which uses photo-realistic
animation based on the rovers' own photos to dramatize their trials and
tribulations, features several of the twins' drivers, as well as their
principal investigator Steven Squyres.
"Astonishingly
accurate," Squyres said of the program's recreations of the Martian surface.
"The guy who did that was a guy named Dan Maas, who I've known 10 years
now and has been working on this stuff forever. He is just a real stickler for
detail, so both depictions of the Martian terrain and depictions of the rovers
are as accurate as I think anyone can possibly make them."
"They
are the closest I think that you can come to what it would be like standing
there, looking at it on
the Martian surface," continued Squyres. "Dan's animations as
they were produced for ["Five Years on Mars"] are just lovingly
created over months and months of work and we don't have that luxury, so what
we use to operate the rovers is not nearly as good as what you see in the
show."
Exploring opposite
sides of Mars since January 2004, the two golf cart-size rovers' adventures
unfold during "Five Years" in soap opera fashion, as the focus is
alternated between the "lucky" Opportunity and the not-so-fortunate
Spirit.
"That
was certainly the way it was at first," Squyres told collectSPACE.com
in an interview, "Opportunity was definitely the lucky one, with all the
sexy evidence of water and everything laid out right in front, literally seven
meters in front of the rover when we landed."
As the
program shows, Opportunity's landing in a shallow crater in Meridiani Planum
gave Squyres and his team a first look at a rock outcropping on Mars, which in
turn led to the discovery of "blueberries," small hematite spheres
that provided the direct evidence of past water. From that point forward,
Opportunity's luck just grew. From the wind gusts that cleaned its solar panels
to its mostly smooth transit across the Martian dunes (less a particularly
trying sand trap), Opportunity's eight miles on Mars have proved its name to be
appropriate.
If
Opportunity was taking full advantage of its opportunity for discovery,
Spirit's landing left Squyres' spirit decidedly down.
"Spirit
got lucky too, but much later," he admitted. In the show, Squyres goes on
to say that while he was reluctant to say it at the time, Spirit's landing site
was a "crushing disappointment".
Touching
down two weeks before its twin, Spirit landed in Gusev crater, which was believed
to be the site of a past lake. Instead of finding evidence of water however,
Spirit found only volcanic rock. Making the best of the situation Squyres
directed the rover team to drive to the nearby but yet more distant than anyone
had planned Columbia Hills. Spirit, as Squyres acknowledged, ultimately did get
lucky but only after losing use of one of its wheels, which led to it scraping
away the Martian soil to discover silica, a clue towards the existence of
microbial life.
Whether
faced with good or bad luck, the rovers' teams at NASA's Jet Propulsion
Laboratory became attached to 'their' rover, rooting for its success, though
not Squyres.
"I am
deeply attached to both of these things. They have both done magnificently. It's
like I have kids and it's like asking which of my two kids I love better,"
he said. "They are different, but I love them both."
