Sol 24 drive


Curiosity has completed its fourth drive sequence since landing on August 6. This drive took it 21m further east, bringing it to around not less than 380m nearer to its destination, Glenegl.

I have managed to produce a panorama using the navigation camera shots that the rover usually takes after every major drive (in order to update its position). Its not my best pan job but it serves the purpose of illustration. A good chap from unmannedspaceflight.com has started to produce kml files showing the position of the rover which we can view on Google Earth. So we can compare the two views.

The total mileage so far should be not less than 43m (that’s only an estimate as I don’t remember how many metres they drove in the first drives, only how far they went from Bradbury Landing).

In other news, NASA has released a brand new HiRISE image from MRO (the telescopic camera in orbit that can see desk-sized objects on the surface) taken of the rover and its scattered landing hardware and it’s better than previous images because the angle of roll (the angle between the camera’s line of sight and the line perpendicular to the surface which would be ‘nadir’) was only 9 degrees which would improve the imaging quality as your subject isn’t placed so far away. It also means less of the atmosphere in the way which would otherwise produce a worse shot with the increased amount of dust in the way.

You can see plenty of debris around the rover in exquisite detail (you can even see, in the ballooned insets, the rover’s wheels, shadow of its mast and the RTG [radioisotope thermal generator] attached to the back of the rover).

It’s now approaching evening of sol 25 at the landing site. Stay tuned.
