Live Spacewalk: Watch as astronauts complete the intricate process of repairing the Alpha Magnetic Spectrometer (AMS), a dark matter and antimatter detector outside the International Space Station.
On Sat., Jan. 25 at 6:50 a.m. EST, tune in for a live spacewalk as Luca Parmitano of the European Space Agency (ESA) and Andrew Morgan of NASA perform the fourth and final spacewalk to repair AMS, which has far outlived its planned three-year lifespan. In addition to revitalizing an important piece of scientific equipment, the process of creating the tools and procedures for these spacewalks is preparing teams for the types of spacewalks that may be required on Moon and Mars missions.
