An Orbital Sciences Corp. Pegasus XL air-launched rocket is in final preparation to send a NASA scientific satellite into polar orbit to study a poorly understood region of the Sun's atmosphere in unprecedented detail. The Interface Region Imaging Spectrograph (IRIS) (see image) will combine an ultraviolet telescope and a multi-channel imaging spectrograph to study the interface region between the visible surface of the Sun and its upper atmosphere, which is the source of most of the Sun's UV radiation.
NASA's long-lived Opportunity rover is rolling toward a new destination at Endeavour Crater on Mars, following one of the nine-year mission's most striking discoveries, a rock rich in clay minerals that points to an early, biologically friendly era dominated by water with a neutral chemistry.
