Astronauts aboard the International Space Station have kicked off a four-year study of vision problems that surfaced among crewmembers several years ago and now rank among the top health concerns facing those selected for future deep-space missions. Nineteen ISS astronauts have developed symptoms of impaired vision since the ailment was first recognized in 2005, according to Dr. Christian Otto, principal investigator for the NASA-sponsored Prospective Observational Study of Ocular Health.
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. Opportunity's internal examination of the rock Esperance in a region known as Cape York on the crater's rim has produced findings strikingly similar to those from rock analysis by NASA's Curiosity rover at the Yellowknife Bay region of distant Gale Crater.
