Looking closer around ThePhoenix Lander we start to notice a few objects that are crying out to be looked at closer. It could be nothing but one gets a feeling of devastion! We leave it for the public to decide as we can all see what we want to see.
But our initial study of one of the objects reveals stunning anomalies!
The images are cropped from the 360-degree view from NASA's Phoenix Mars Lander shows the
spacecraft's solar arrays, lander deck and the Martian polar landscape
beyond. The hummocky terrain has a network of troughs and very few
rocks, typical of polar surfaces here on Earth.
Phoenix's Surface Stereo Imager captured the images making up
this mosaic on the first and third martian days, or sols, of the
mission (May 26 and 28, 2008). The spacecraft is capable of taking
color, high-resolution photos, but its first priority is to scan its
surroundings with black-and-white, lower-resolution images like these.

Nasa image of the Day |
| Snapshot of the International Space Station |  | | On March 13, 2008, the International Space Station passed across the field-of-view of Germany's remote sensing satellite, TerraSAR-X, at a distance of 195 kilometers, or 122 miles, and at a relative speed of 34,540 kilometers per hour, or more than 22,000 mph. In contrast to optical cameras, radar does not 'see' surfaces. Instead, it is much more aware of the edges and corners which bounce back the microwave signal it transmits. Smooth surfaces such as those on the station's solar generators or the radiator panels used to dissipate excess heat, unless directly facing the radar antenna, tend to deflect rather than reflect the radar beam, causing these features to appear on the radar image as dark areas. The radar image of the station therefore looks like a dense collection of bright spots from which the outlines of the space station can be clearly identified. The central element on the station, to which all the modules are docked, has a grid structure that presents a multiplicity of reflecting surfaces to the radar beam, making it readily identifiable. This image has a resolution of about one meter (about 39 inches). In other words, objects can be depicted as discrete units--that is, shown separately--provided that they are at least one meter apart. If they are closer together than that, they tend to merge into a single block on a radar image. Since this image as taken, the station has expanded and is more than 90 percent complete, including a full complement of solar arrays.
