We report on the prospects for the study of the first stars, galaxies and black holes with the Generation-X Mission. Generation-X is a NASA "Vision Mission" which completed preliminary study in lat e2006. Generation-X was approved in February 2008 as an Astrophysics Strategic Mission Concept Study (ASMCS) and is baselined as an X-ray observatory with 50 square meters of collecting area at 1 keV (500 times larger than Chandra) and 0.1 arcsecond angular resolution (several times better than Chandra and 50 times better than the Constellation-X resolution goal). Such a high energy observatory will be capable of detecting the earliest black holes and galaxies in the Universe, and will also study the chemical evolution of the Universe and extremes of density, gravity, magnetic fields, and kinetic energy which cannot be created in laboratories. A direct signature of the formation of the first galaxies, stars and black holes is predicted to be X-ray emission at characteristic X-ray temperatures of 0.1-1 keV from the collapsing proto-galaxies before they cool and form the first stars.
