The space adventure comes to a conference at CERN Conferencias en Noviembre Live video courtesy of CERN 2012
The 4th International Conference on Particle and Fundamental Physics in Space (SpacePart12) will take place at CERN from 5 November to 7 November 2012. Space scientists and space policy makers from around the world have registered for this year’s conference, which coincides with the centenary of the discovery of cosmic rays. Two of the biggest names in space exploration have been invited to give special talks open to the general public at CERN on 5 and 6 November.
At 8pm on 5 November, Edward Stone, professor at the California Institute of Technology and project scientist for the Voyager probes since 1972, will give a talk on the extraordinary story of these two probes, launched 35 years ago. His talk will be preceded by an introduction from Samuel Ting, principal investigator for the Alpha Magnetic Spectrometer experiment installed on the International Space Station (ISS).
At 8pm on 6 November William Gerstenmaier, associate administrator for Human Exploration and Operations for NASA and former manager of the ISS Program, will discuss the scientific work being conducted on the space station.
The talks will be webcast here in English, with French interpretation provided.

|Abstract||The question “What is the Universe made of?” is the longest outstanding problem in all of physics. Ordinary atoms only constitute 5% of the total, while the rest is of unknown composition. Already in 1933 Fritz Zwicky observed that the rapid motions of objects within clusters of galaxies were unexplained by the gravitation pull of luminous matter, and he postulated the existence of Dunkle Materie, or dark matter. A variety of dark matter candidates exist, including new fundamental particles already postulated in particle theories: axions and WIMPs (weakly interacting massive particles). Over the past 25 years, there has been a three pronged approach to WIMP detection: creating them at particle accelerators; searched for detection of astrophysical WIMPs scattering off of nuclei in underground detectors; and “indirect detection” of WIMP annihilation products (neutrinos, positrons, or photons). As yet the LHC has only placed bounds rather than finding discovery. For 13 years the DAMA experiment has proclaimed evidence of annual modulation of the signal which could be evidence of detection. Over the past few years the situation has become very exciting as many different experiments are independently seeing unexplained results; yet the various experiments do not seem to agree. The hunt for dark matter has become very exciting and yet very puzzling. This talk will describe the current anomalies that may herald WIMP discovery.|
