  e2v CCD imaging sensors are launched into space onboard Kepler - NASA’s first
             mission capable of finding Earth-size planets around other stars

On the 6th March 2009, e2v’s high performance CCD (Charge Coupled Device) imaging
sensors were launched into space onboard the Kepler spacecraft as it successfully lifted off
from Cape Canaveral, Florida onboard a Delta II rocket on its 3 ½ (or more) year mission.

Kepler has been designed by NASA and Ball Aerospace & Technology Corp. to simultaneously
monitor, from space, more than 100,000 stars in our galaxy. It will observe sun-like stars, seeking
to discover Earth-like planets whose orbits about their star are at distances where liquid water can
exist, and therefore perhaps life could form.

Ball Aerospace designed, built and tested Kepler’s photometer, a specially designed 0.95 m
aperture, wide field-of-view Schmidt telescope, with a 1.4m primary mirror. With more than 95
megapixels, Kepler’s focal plane array of 42 e2v backside illuminated CCD90s forms the largest
array of CCDs ever launched into space by NASA. The CCDs are not used to take sharp pictures.
The images are intentionally defocused to about 10 arc seconds to improve the photometric

The 42 e2v CCD90s populating the focal plane array have the following characteristics:

    •   2200 x 1044 active pixels; 27 um size; 28 x 55 mm image area.

    •   Back thinned for high spectral response across the visible and near-IR range.

    •   Low noise and large signal handling characteristics, with stable performance.

    •   Precision flatness and device location within a custom package.

    •   3 MHz read-out rate.
Margaret A. Frerking, Kepler’s Deputy Project Manager from NASA JPL, said “Kepler, with its large
focal plane array, will let us observe over 100,000 stars simultaneously and discover as many as
100 earth like planets during the course of the mission.”

"e2v's imaging sensors are the heart of the Kepler mission," said John Troeltzsch, Ball Aerospace
program manager. "The CCDs will allow Kepler to detect Earthlike planets orbiting in the habitable
zone around other stars and possibly answer the million dollar queston, 'Are we alone?'"

Brian McAllister, General Manager of Space & Scientific Imaging at e2v said “e2v is proud to be
able to help NASA accelerate discovery by supplying imaging sensors for this telescope. This will
be the largest camera launched in space and promises some exciting discoveries”.

The NASA Ames Research Center is home to Kepler’s science principal investigator, and is also
responsible for the ground system development, mission operations and science data analysis.
Kepler mission development is managed by the Jet Propulsion Laboratory.            Operation of the
spacecraft after launch will be performed by the Laboratory for Atmospheric and Space Physics at
the University of Colorado, Boulder, with Ball providing system engineering and mission planning.
