Yesterday evening the space shuttle Discovery blasted off from Cape Canaveral to dock with the Mir Space Station for the last time. Apart from picking up US astronaut Andrew Thomas, the shuttle will carry the first particle physics experiment into space. The Alpha Magnetic Spectrometer (AMS) will spend ten days searching for anti-helium and anti-carbon, and measuring the energy spectra of positrons and antiprotons. The shuttle will also carry the first Internet router in space. Researchers will be able to remotely access their experiments in real time simply by using standard Internet software.
