The vehicle appears as a double dot.
The view from the Mars Reconnaissance Orbiter (MRO) has been colour enhanced to emphasise certain ground features.
These include the disturbance in the soil made either side of the vehicle by the rocket powered crane that lowered Curiosity into Gale Crater a week ago.
"We can clearly see Curiosity - it's like two bright spots that we see, and their shadows. And then it's surrounded by the blast pattern from the descent stage - those little blue fans right next to it (false colour blue)," explained Alfred McEwen, the principal investigator on MRO's High Resolution Image Science Experiment (HiRise) camera.
Since its 6 August (GMT) touchdown, engineers have been checking out the rover's systems and instruments.
And the past four days have been spent upgrading the vehicle's onboard software.
Curiosity runs two computers - a main unit and a back-up. Both have been updated to what programmers call the R10 configuration.
This software is optimised for surface operations, enabling the rover to drive, drill into rocks and take samples into the laboratories inside its body.
The update also removed all the code used by Curiosity during the complex manoeuvres required to land in Gale Crater, a deep depression on Mars' equator.
Curiosity Cradled by Gale Crater
NASA's Curiosity rover landed in the Martian crater known as Gale Crater, which is approximately the size of Connecticut and Rhode Island combined. A green dot shows where the rover landed, well within its targeted landing ellipse, outlined in blue.
This oblique view of Gale, and Mount Sharp in the center, is derived from a combination of elevation and imaging data from three Mars orbiters. The view is looking toward the southeast. Mount Sharp rises about 3.4 miles (5.5 kilometers) above the floor of Gale Crater.
The image combines elevation data from the High Resolution Stereo Camera on the European Space Agency's Mars Express orbiter, image data from the Context Camera on NASA's Mars Reconnaissance Orbiter, and color information from Viking Orbiter imagery. There is no vertical exaggeration in the image.

Why is the blast pattern blue though?

The colors have been enhanced in this image – which actually makes things very interesting. As I’ve pointed out before, most of Mars is covered in basalt, a blue-gray rock. When you hear about sand on Mars, it’s usually coarse-grained stuff made up of eroded basalt. However, there’s also much finer-grained dust which is high in iron oxide – rust – and it’s that which gives Mars its characteristic ruddy color.
That fine dust covers everything, making the planet red/orange/ochre. But there’s wind on Mars, and it can blow the dust around, revealing the grayer basalt underneath (like the dust devils do). And if there’s no natural wind, why, the thrusters from the rockets of a sky crane hovering over the surface as it lowers a one-ton rover to the ground will do just fine.

Just out of curiosity...
Do these hi res cameras take video?:shrug:
I couldn't think of a better place for this...

A Russian neutron detector on board NASA’s Mars rover Curiosity, designed to search for any water that might be bound into shallow underground minerals along the rover's path, was activated on Friday, the manufacturer said.
“The first scientific information has been received about the substance of Mars and its radiation background in the landing area,” the Russian Academy of Sciences Space Research Institute said.

It is important to realize that clouds, fogs and hazes can have some proportion of liquid water even well below freezing temperature. This is well known to happen when salts are dissolved in the water through freezing point depression. But it can also happen with pure water through supercooling:
Supercooling.

The temperature at which supercooled liquid water can occur can even be below -40C, which coincidentally is also -40F:
Supercool Water.

"Liquid water as cold as minus 40 F has been found in clouds. Scientists have done experiments showing liquid water can exist at least down to minus 42 F."
