Max (Karl Ernst Ludwig) . 1858--1947, German physicist who first formulated the quantum theory (1900): Nobel prize for physics 1918

Planck

A space mission planned by the European Space Agency (ESA) for the purpose of surveying and mapping the anisotropies of the Cosmic Microwave Background (CMB) over the whole sky. The Planck spacecraft is scheduled to be launched by ESA in early 2007 and is to share its launch vehicle – an Ariane 5 rocket – with the Herschel Space Observatory. After launch, the two craft will separate and be placed into different orbits around L2, one of the Lagrangian points of the Earth–Sun system. In this stable location 1.5 million kilometers from the Earth, almost wholly isolated from extraneous particle and radiation interference, the Planck observatory will be able to map the CMB anisotropies with improved sensitivity and angular resolution. It will also be able to help measure accurately the amplitude of the structures in the CMB. Planck will provide a major and up-to-date source of information on such issues as the accurate determination of the Hubble Constant and the testing of inflationary models of the early universe. The mission takes its name from Max Planck, the German theoretical physicist and creator of the quantum theory.
