In the wake of successfully dropping the SUV-sized Curiosity rover on
Mars this month, NASA will send another robot to the Red Planet in 2016
to drill into the planet's crust and, for the first time, piece together
a picture of the Martian interior.

The $425 million robotic lander, named InSIGHT, will be built and
operated by the Jet Propulsion Laboratory at the California Institute of
Technology, the high-flying hotbed of now-famous engineers and
scientists who designed and assembled the $2.5 billion Curiosity rover
and its heart-stopping "sky crane," which lowered the Curiosity rover to
the Martian surface.

On Monday morning, NASA officials informed JPL staff that InSIGHT had
won funding over two other proposed missions.

"This is another big day for us out at JPL," said Gregg Vane, the lab's
head of planning for solar system exploration.

Whereas Curiosity can roam the surface on six-wheels, InSIGHT will be
planted in one spot after dropping onto the Martian surface - minus the
sky crane - in September 2016.

A German-built drill nick-named "the mole" will pound 30 feet into the
Martian crust to take the temperature of the planet, while a sensitive
French-built seismometer will detect any Marsquakes. Together, the
instruments will provide vital clues to how Mars formed.

"We'll be able to deduce the deep structure of Mars, which now is a
total mystery," said Vane. "That means all the way down to the core."

To date, scientists have determined the deep structure of only one
planet - Earth. They know the interior of Mars must be different,
because Mars has no magnetic field to shield its surface from radiation.
Earth, by contrast, has a strong magnetic field generated by a spinning
molten iron core.

Except for the drill and seismometer, which are new, InSIGHT will be a
near-copy of the Phoenix lander NASA dropped onto Mars in 2008, which
found water ice near the Martian north pole.

In choosing InSIGHT, NASA rejected two riskier missions: a robotic boat
that would have floated on a methane lake on Saturn's moon Titan, and a
mission to examine a comet.

Meanwhile, Curiosity has begun shooting its laser "ChemCam" on Mars,
blasting a rock Sunday in a successful test of the instrument, which can
determine the composition of surface minerals by examining flashes of
vaporized gas.
