A “discussion draft” of a two-year NASA reauthorization bill is running into bipartisan opposition in its originating House space subcommittee, illustrating how lawmakers' divergent opinions about NASA spending are inhibiting progress.

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.
