End of an era: Space station received last of NASA’s science racks

It can be called as an end of an era for the International Space Station as one of its longer chapter is ending. 19-years after sending the first 2 racks of 11 ExPRESS, NASA has sent its last 2 racks to the orbiting facility. A Japanese cargo ship has carried the last two racks that should be functioning by fall 2020. The racks will remain useful for a while, however, this effectively marks the end of NASA’s ISS work.
