15 October 2009: First complete set of results from IBEXThe IBEX first heliospheric results and sky maps have been presented to the scientific community and public audience. The first results are summarized in five papers published by Science Magazine. The sky maps of hydrogen energetic atoms in different energy bands show unexpected features. In addition, the IBEX team has published the first ever direct detection of interstellar neutral hydrogen and oxygen, drifting into the heliosphere from the interstellar medium.

19 October 2008: Launch of IBEXThe first NASA spacecraft to image and map the dynamic interactions taking place where the hot solar wind slams into the cold expanse of space launched from an Orbital Sciences Pegasus XL rocket at 1:48 p.m. EDT on Oct. 19, 2008 from the Reagan Test Site on the Kwajalein Atoll in the Marshall Islands (South Pacific, a few degrees north of the equator). The IBEX spacecraft will conduct extremely high-altitude orbits above Earth (bringing it quite close to the Moon at times) to investigate and capture images of processes taking place at the farthest reaches of the solar system. Known as the interstellar boundary, this region marks where the solar system meets interstellar space.
