NASA's Curiosity Rover Caught in the Act of Landing

PASADENA, Calif. – An image from the High Resolution Imaging Science Experiment (HiRISE)
camera aboard NASA's Mars Reconnaissance Orbiter captured the Curiosity rover still connected to
its 51-foot-wide (almost 16 meter) parachute as it descended towards its landing site at Gale Crater.

"If HiRISE took the image one second before or one second after, we probably would be looking at
an empty Martian landscape," said Sarah Milkovich, HiRISE investigation scientist at NASA's Jet
Propulsion Laboratory in Pasadena, Calif. "When you consider that we have been working on this
sequence since March and had to upload commands to the spacecraft about 72 hours prior to the
image being taken, you begin to realize how challenging this picture was to obtain."

The image of Curiosity on its parachute can be found at:

The image was taken while MRO was 211 miles (340 kilometers) away from the parachuting rover.
Curiosity and its rocket-propelled backpack, contained within the conical-shaped back shell, had yet
to be deployed. At the time, Curiosity was about two miles (three kilometers) above the Martian
surface.

"Guess you could consider us the closest thing to paparazzi on Mars," said Milkovich. "We definitely
caught NASA's newest celebrity in the act."

Curiosity, NASA's latest contribution to the Martian landscape, landed at 10:32 p.m. Aug. 5, PDT,
(1:32 on Aug. 6, EDT) near the foot of a mountain three miles tall inside Gale Crater, 96 miles in
diameter.

In other Curiosity news, one part of the rover team at the JPL continues to analyze the data from last
night's landing while another continues to prepare the one-ton mobile laboratory for its future
explorations of Gale Crater. One key assignment given to Curiosity for its first full day on Mars is to
raise its high-gain antenna. Using this antenna will increase the data rate at which the rover can
communicate directly with Earth. The mission will use relays to orbiters as the primary method for
sending data home, because that method is much more energy-efficient for the rover.

Curiosity carries 10 science instruments with a total mass 15 times as large as the science payloads on
the Mars rovers Spirit and Opportunity. Some of the tools are the first of their kind on Mars, such as a
laser-firing instrument for checking rocks' elemental composition from a distance. Later in the
mission, the rover will use a drill and scoop at the end of its robotic arm to gather soil and powdered
samples of rock interiors, then sieve and parcel out these samples into analytical laboratory
instruments inside the rover.

To handle this science toolkit, Curiosity is twice as long and five times as heavy as Spirit or
Opportunity. The Gale Crater landing site places the rover within driving distance to layers of the
crater's interior mountain. Observations from orbit have identified clay and sulfate minerals in the
lower layers, indicating a wet history.

The mission is managed by JPL for NASA's Science Mission Directorate in Washington. The rover
was designed, developed and assembled at JPL.

HiRISE is operated by the University of Arizona, Tucson. The instrument was built by Ball
Aerospace & Technologies Corp., Boulder, Colo. The Mars Reconnaissance Orbiter Project and the
Mars Exploration Rover Project are managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif.,
for NASA's Science Mission Directorate, Washington. JPL is a division of the California Institute of
Technology in Pasadena. Lockheed Martin Space Systems, Denver, built the orbiter.
