Heliophysics

IBEX's orbit takes it up to 200,000 miles

from Earth.

Six months into its mission, IBEX

surveyed the entire sky to reveal the

structure of the edges of our solar

system.

Mission Description

As part of a Southwest Research Institute team led by Principal Investigator Dr. David McComas,

Orbital was selected in January 2005 to develop, build and launch a small spacecraft for NASA’s

Interstellar Boundary Explorer (IBEX) mission. The spacecraft is based on Orbital’s LEOStar-1™

spacecraft product line.

The IBEX satellite orbits the Earth every eight days on a highly-elliptical path that takes it to an apogee

of 320,000 kilometers (approximately 80 percent of the distance to the Moon) to make the rst

comprehensive map of the boundary between our Solar System and interstellar space. Measuring

this interstellar interaction is important for understanding our protection from galactic cosmic rays –

energetic particles from beyond the Solar System – that could pose health risks to future astronauts

exploring deep space.

IBEX was launched on October 19, 2008, aboard Orbital's Pegasus

launch vehicle from the

Kwajalein Atoll launch site in the central Pacic Ocean. The spacecraft incorporated an on-board

solid rocket motor and hydrazine propulsion system to propel it to the nal high-altitude orbit beyond

Earth’s magnetosphere, as required by IBEX’s scientic instrument.

Spacecraft

The IBEX spacecraft is based on Orbital’s highly reliable LEOStar-1 spacecraft platform, subsystems

and supporting software, which has a proven track record of success on a total of 45 missions.

The payload consists of two narrow angle image sensors (IBEX-Hi and IBEX-Lo) and a Combined

Electronics Unit (CEU).
