Space Station Live: January 4, 2016

NASA has ordered four additional launches to deliver cargo to the International Space Station in 2017 — three from SpaceX and one from Orbital ATK — to cover the research lab’s logistics needs until a new set of resupply contracts take effect.

Two cosmonauts ventured outside the International Space Station, jettisoning three no-longer-needed components and carrying out a photo survey of the Russian segment of the lab complex in the seventh and final spacewalk planned by the station crew this year.

Russia is delaying the return to Earth of three space station crew members by about a month in the wake of the failure of a Russian Progress supply ship that spun out of control moments after reaching orbit April 28. Launch of three fresh crew members also will be delayed, from May 26 to late July.
