Astro-H is the latest satellite in the collaboration between NASA and ISAS. It is currently targeted to launch in 2015, and the project scientists and engineers are working hard to make this satellite a reality.
Suzaku has been actively taking data since its launch in 2005. It is a re-flight of the failed Astro-E satellite – showing that the collaboration can survive both success and failure.
ASCA was launched in 1993 and made over 3000 observations of the X-ray sky in its 8 years of operations.
Ginga was the first X-ray astronomy collaboration between agencies in the U.S. and ISAS, which forged the way for future collaborations with NASA. It operated from 1987 until 1991.
