Return from space: from the International Space Station to CERN

On 16 May 2011, the space shuttle Endeavour took off for the last time from Cape Canaveral in Florida with six astronauts on board. Their mission (code-named STS-134) was to install the Alpha Magnetic Spectrometer (AMS), the dark matter and antimatter detector designed at CERN, on the International Space Station. Since then, AMS has been sending data to CERN from space.


On Wednesday 25 July do not miss a rare opportunity to meet the mission’s six astronauts at CERN:

Mark E. Kelly, commander (NASA)
Greg H. Johnson, pilot (NASA)

and the mission’s specialists:

Michael Fincke (NASA)
Roberto Vittori (ESA and ASI)
Andrew J. Feustel (NASA)
Greg Chamitoff (NASA)

4:20 pm: the event will kick off with a photo and autograph session at the Globe of Science and Innovation.

5 pm: lecture given by the astronauts for CERN personnel and summer students in the Main Auditorium. (Seats reserved for the summer students - contact:

In addition, there will be an exhibition at Microcosm, which will be open to the public, of photographs from AMS’s flight in space.  A book on the exhibition will be on sale at the CERN shop.
