Curiosity's New Home
These are the first two full-resolution images of the Martian surface from the Navigation cameras on NASA's Curiosity rover, which are located on the rover's "head" or mast. The rim of Gale Crater can be seen in the distance beyond the pebbly ground.
The topography of the rim is very mountainous due to erosion. The ground seen in the middle shows low-relief scarps and plains. The foreground shows two distinct zones of excavation likely carved out by blasts from the rover's descent stage thrusters.

Scene of a Martian Landing
The four main pieces of hardware that arrived on Mars with
NASA's Curiosity rover were spotted by NASA's Mars Reconnaissance Orbiter
(MRO). The High-Resolution Imaging Science Experiment (HiRISE) camera captured
this image about 24 hours after landing. The large, reduced-scale image points
out the strewn hardware: the heat shield was the first piece to hit the ground,
followed by the back shell attached to the parachute, then the rover itself
touched down, and finally, after cables were cut, the sky crane flew away to
the northwest and crashed. Relatively dark areas in all four spots are from
disturbances of the bright dust on Mars, revealing the darker material below
the surface dust.
Around the rover, this disturbance was from the sky crane
thrusters, and forms a bilaterally symmetrical pattern. The darkened radial
jets from the sky crane are downrange from the point of oblique impact, much
like the oblique impacts of asteroids. In fact, they make an arrow pointing to
Curiosity.
The Curiosity rover is approximately 4,900 feet (1,500
meters) away from the heat shield; about 2,020 feet (615 meters) away from the
parachute and back shell; and approximately 2,100 feet (650 meters) away from
the discoloration consistent with the impact of the sky crane.

First Color Image from Mars by Curiosity
This view of the landscape to the north of NASA's Mars rover Curiosity taken by the Mars Hand Lens Imager (MAHLI) on the afternoon of the first day after landing. (The team calls this day Sol 1, which is the first Martian day of operations; Sol 1 began on Aug. 6, 2012.)
In the distance, the image shows the north wall and rim of Gale Crater. The image is murky because the MAHLI’s removable dust cover is apparently coated with dust blown onto the camera during the rover’s terminal descent. Images taken without the dust cover in place are expected during checkout of the robotic arm in coming weeks.
Mars Robot Size Comparison
Take a look at this size comparison of the robots sent to Mars...It explains why Spirit, Opportunity and Sojourner could use the bouncing balloon (airbag) landing and Curiosity used the sky-crane landing. Curiosity's EDL (Entry, Descent and Landing) also allowed for much greater accuracy in hitting a particular landing site.

Curiosity
Why is the Mars Curiosity Rover so interesting to me? Because it is the most sophisticated robotic planetary explorer ever built or conceived. Everything about it is hard to do. It also bears a name that means so much to me.
See the quote from Walt Disney to the right (and below)...It is kind of the theme of my blog and something that I think captures the whole idea of why we should try new things and always be learning...It was featured in Disney's animated film Meet the Robinsons.
"We keep moving forward, opening new doors, and doing new things, because we're curious and curiosity keeps leading us down new paths." - Walt Disney

This is a combination of video and simulation pieced together to show the moment that Curiosity landed on Mars.
