NASA launched Kepler in March 2009.
The spacecraft is dedicated to the discovery of extrasolar planets by the transit method from solar orbit.
In April 2009 the project released the first light images from the spacecraft, and TrES-2b was one of two objects highlighted in these images.
Although TrES-2b is not the only known exoplanet in the field of view of this spacecraft it is the only one identified in the first light images.
This object is important for calibration and check-out.

The Kepler mission also managed to detect the mass of the planet from Kepler data alone through the analysis of the light curve of the host star.
In addition to detecting the planet directly, the planet was also detected by analysis of the star brightness caused by the gravitational tug of TrES-2b by shape distortion of the host star and by light variations due to Doppler beaming.
