Bladder lining, SEM

Bladder lining. Coloured scanning electron micrograph (SEM) of the internal surface folds of a bladder in its contracted state. The bladder is the organ that receives and stores urine from the kidneys. The walls of the bladder (a hollow organ) have to expand and contract to cope with varying volumes of urine. Urine is a waste product that is produced by the kidneys. The kidneys filter the blood to remove metabolic waste such as urea. The resulting urine drains from the kidneys through the ureters into the bladder. The urine is then removed from the body by urination through the urethra. Magnification unknown

Artwork depicting MFEX rover on Mars

Mars rover. Artist's impression of the Micro-rover vehicle "Sojourner" on the surface of Mars. Sojourner will be carried to Mars by the Mars Pathfinder spacecraft, seen here in the background in late 1996. The rover weighs about 9kg, is 63cm long and 48cm wide. It is powered by a solar panel which will allow for a few hours movement per day, and is controlled by an operator on Earth. The main objective of Sojourner is to study rocks on the surface of Mars. To this end it carries an alpha-proton X-ray spectrometer (APXS) and a high-resolution camera. Sojourner will also provide extensive engineering data toward the design of future planetary rover vehicles
