University of Colorado at Boulder undergraduates, who have been helping to control five NASA satellites from campus, participated in the unusual decommissioning of a functioning satellite with a failed science payload in recent days, bringing the craft into Earth re-entry to burn up yesterday.

Large changes in the sun's energy output may drive unexpectedly dramatic fluctuations in Earth's outer atmosphere, new research indicates. A study published today links a recent, temporary shrinking of a high atmospheric layer with a sharp drop in the sun's ultraviolet radiation levels.

Postdoctoral fellows and graduate students from Professor Mark Hernandez's environmental engineering lab at the University of Colorado at Boulder will travel to the Gulf Coast this week to begin studying the effect of this summer's oil spill on air quality along impacted shores.
