Curiosity, Sharp Shooter

Ansel Adams, eat your heart out.

On the opposite side of the rover, one of Curiosity's eight hazard-avoidance cameras shot this black-and-white picture of the rover's shadow stretching toward Mount Sharp on Monday.

Centered in Gale Crater, the 18,000-foot (5,500-meter) peak "is taller than any mountain in the lower 48 [U.S.] states," geologist John Grotzinger, part of the Curiosity team, said at a July 16 press conference. The goal is for the rover—also called the Mars Science Laboratory—to climb Mount Sharp and analyze layers spanning all of Mars's major geological epochs.

Along the way, the so-called Hazcams will help spot obstacles that could stymie even this remarkably capable rover.

Curiosity is capable of climbing slopes inclined up to 30 degrees, depending on the firmness of the surface.

"We [have done] simulations with the engineering teams to find paths that we could be very secure in," Grotzinger said. "If one doesn't work, we can go down and pick another."

Two and a half minutes before landing Monday—and four miles (seven kilometers) up—Curiosity's Mars Descent Imager (MARDI) snapped this low-resolution picture of its falling, 15-foot-wide (4.5-meter-wide) heat shield.

The shield, which protected the rover from 3,500-degree (1,900-degree-Celsius) friction heat during the descent, is shown three seconds after being ejected by the Mars rover.

The shield's separation was crucial to expose not only Curiosity's wheels but also its underside radar equipment. The radar enabled Monday's flawless landing by providing crucial altitude and velocity data. (Pictures: Mars Rover's "Crazy" Landing, Step by Step.)

High above Curiosity, NASA's Mars Reconnaissance Orbiter (MRO) caught this picture of the rover dangling from its parachute about one minute before landing on Monday. The parachute cords can't be seen, but details of the parachute design are clearly apparent.

Shortly after this image was taken, the rover released its upper heat shield (visible above) and the attached parachute to begin the rocket-powered phase of Curiosity's descent.

The parachute picture was no snap to take. MRO's HiRISE camera team needed months to make sure the orbiter was pointed in precisely the right direction at the right time. (Video: Mars Curiosity Rover Landing a Success-NASA Jubilant.)

"We rely on the engineers to calculate everything perfectly for us," HiRISE camera team leader Alfred McEwen told the Arizona Daily Star. "You just have to double- and triple- and quadruple-check everything."

Another Monday picture by the orbiter shows Curiosity's parachute, still attached to the upper heat shield, on Mars—a safe distance from the landing spot of the rover itself.

Crash Scene Investigation

Looking something like scorch marks, the dark areas shown in an orbiter's picture were actually created by the planned crash of the "sky crane" lander, which exposed darker, lower Martian soil Monday. While hovering above Mars earlier, the rocket-powered lander gingerly lowered Curiosity to the surface.

When Curiosity was safely on the ground and the sky-crane tethers released, the rocket used its remaining fuel to zip toward its doom at an angle, to avoid crashing atop the rover. The lander itself is too small to be seen, but the longest streaks are about 400 feet (120 meters) long.

In addition to the parachute, upper heat shield, and sky-crane vehicle, NASA scientists believe that they've spotted both the rover and its lower heat shield in images from the orbiter. So far, however, these two are only tiny dots in the wide-angle photos of Gale Crater.
