When it comes to studying the region of interstellar space just beyond our solar system, nothing seems to work quite the way scientists imagined. A strange interstellar wind blows through our ...

The Interstellar Boundary Explorer (IBEX) is a small satellite already orbiting Earth. IBEX has special instruments gathering ...

The Interstellar Boundary Explorer (IBEX) is NASA's next Small Explorer. The Explorer Program develops low-cost, rapidly developed space science investigations.

NASA's Interstellar Boundary Explorer mission, or IBEX, successfully launched from the Kwajalein Atoll in the Pacific Ocean Sunday. IBEX will be the first spacecraft to image and map dynamic ...

For over a decade, NASA's Interstellar Boundary Explorer (IBEX) has been probing the outer edge of the heliosphere, or the 'bubble' that surrounds our solar system, to better understand the ...

NASA launched the Interstellar Boundary Explorer (IBEX) spacecraft last year to investigate the edges of the heliosphere — the insulating bubble the sun creates around the solar system. IBEX ...

June 19, 2009. NASA’s Interstellar Boundary Explorer (IBEX) spacecraft has made the first observations of fast hydrogen atoms coming from the Moon, following decades of speculation and searching ...

As the Southwest Research Institute-led Interstellar Boundary Explorer mission enters the implementation phase, the spacecraft and instrument designs are being completed, and prototype hardware is ...

The results are in from the first all-sky map created by NASA's new Interstellar Boundary Explorer (IBEX) spacecraft, which launched in October 2008. While orbiting Earth, IBEX monitors incoming ...

The Interstellar Boundary Explorer (IBEX) mission will be launched in 2008. IBEX is the first mission designed to detect the edge of the Solar System.
