Astro-E2 was successfully launched on 12:30 pm JST
on July 10, 2005 from the Uchinoura Space Center (USC) in Japan. Soon
after launch, the mission was renamed Suzaku.
Suzaku is the re-build of Astro-E, which was unfortunately lost during launch
(10 February 2000).
Suzaku (as Astro-E) has been developed at the Japanese Institute of Space
and Astronautical Science (ISAS) in collaboration with the US.
This is Japan's fifth X-ray astronomy mission.
Suzaku is the first satellite that carries a new type of X-ray
spectrometer, the X-ray micro-calorimeter, which provides unprecedented
energy resolution compared to non-dispersive instruments.
10 July 2005 - (XRS has ~ 2.5 year lifetime ) Energy Range : 0.2-600 keV Special Features
: First X-ray micro-calorimeter in space
Five nested conical thin-foil grazing incidence telescopes (XRT),
with a angular resolution of ~2 ´ (HPD); all gold-coated.
Focal lenght : 4.75m (XRT-I, 4 units); 4.5m (XRT-S, 1 unit)
At the focus of each telescope there is one of the following detectors :
X-ray Spectrometer (XRS; 0.3-12 keV; one unit)
An X-ray micro-calorimeter composite of 32 pixels
at the foci of the XRT-S.

FOV 2.9´ X 2.9´
X-ray Imaging Spectrometer (XIS; 0.2-12 keV; four units)
Each unit is a 1024 X 1024 pixel CCD detector
at the foci of one XRT-I.
Three CCDs are front illuminated (FI), one is back illuminated (BI)
