IBEX Successfully Launched

October 20, 2008

The Interstellar Boundary EXplorer (IBEX) satellite was successfully launched on Sunday, October 19.  The satellite, which was carried into high Earth orbit on an Orbital Sciences Corp. Pegasus XL rocket, is designed to map the boundary between the solar wind and the interstellar gas by collecting fast neutral atoms that reach Earth from that boundary.  Over the next 45 days, the spacecraft will be raised to a higher orbit and checked for proper operation, after which it will commence collecting data.  The mission has a planned duration of 2 years.
