Curiosity transitions to new software, plans mobility tests

Engineers successfully updated the Curiosity rover's computer software
over the weekend and plan initial tests of the mobile science lab's
ability to drive across the martian terrain within the next week or so,
project officials said Tuesday.

"We couldn't be happier with the success of the mission so far," said
Ashwin Vasavada, Mars Science Laboratory deputy project scientist. "Most
significantly at this point, since we're still in our commissioning
phase, we have a fully healthy rover and payload."

Mission manager Mike Watkins said that with the successful installation
of surface-optimized software, version R10, the initial phase of the
rover's activation and checkout -- phase 1A -- is complete. Engineers
are beginning phase 1B "and that includes a mobility checkout," he said.

"So (we will have) commissioned everything but the (robot) arm and the
drill sampling system after about a week from now," he said. "That means
there's a lot of science we can do. ... We can drive around, go to a
better target, sort of use our remote sensing equipment. And then we
want to go into a phase where we check out all the arm joints, take the
arm out, stretch it, do its wake-up exercises.

"So I think the final completion of characterizing the sampling system
is still a fair ways away, probably a month away or something. But after
the end of this week or so, we have a lot of capability we're able to
turn over to the science team."

Curiosity made a pinpoint landing on the floor of Gale Crater last
Monday. Scientists expect to spend about a year studying the rocks and
soil of the crater floor while Curiosity slowly makes its way to the
base of Mount Sharp, a three-mile-tall mound of layered rocks about five
miles away as the crow flies that represents a major mission objective.

If all goes well, Curiosity will climb the lower slopes of Mount Sharp
in the second half of its planned two-year mission, crossing over beds
that mark the transition from a warmer, wetter past to more recent drier
environments.

"It's fair to say the science team and our rover drivers and really
everybody are kind of itching to move at this point," Vasavada said.
"The science and operations teams are working together to evaluate a few
different routes that will take us eventually to Mount Sharp, maybe with
a few waypoints in between to look at some of this diversity that we see
in these images.

"It's going to take the good part of a year to finally make it to these
sediments on Mount Sharp. So really, we're trying to just keep our eyes
on the prize, finish these checkouts and then get going."

A high-resolution photo snapped by NASA's Mars Reconnaissance Orbiter
was released Tuesday, clearly showing Curiosity on the surface with
radial blast patterns nearby where the rover's sky crane descent engines
blew away topsoil. Another oblique view of Gale Crater, with Curiosity's
actual landing site pinpointed, illustrated the upcoming drive to the
base of Mount Sharp, including a field of sand dunes that must be
traversed.

Using high-resolution orbital photography, the science team has
identified at least six possible routes to the base of the mountain. But
Curiosity will not get there in a hurry.

"Our goal and our scientific mission lies on the lower slopes of Mount
Sharp," Vasavada said. "But part of understanding Mount Sharp is
understanding the context around it and some of the features that have
formed on the plains that we're at. So we'll spend a little time
characterizing the most important units along the way."

But "characterizing" a rock formation will be a time-consuming process
and even though the science teams plans to minimize the number of stops
Curiosity makes on the way to Mount Sharp, it is expected to take about
a year to get there.

"It's probably a few weeks of activity (for each targeted formation
along the way) because it might mean acquiring a sample, for example,
which takes a few weeks to find that place to get the sample, to deploy
the arm, to acquire the sample and process it in our lab," Vasavada
said. "So maybe two or three samples, perhaps, on the way, that's
already a month or two.

"We're still evaluating the capability of the rover on the terrain that
we now see from eye level. ... We estimate we can drive something like a
football field a day once we get going and test out all our driving
capabilities. And if we're talking about a hundred football fields away,
in terms of 10 kilometers or so, to those lower slopes of Mount Sharp,
that already is a hundred days plus."
