Crew 11 is expected to splash down off the coast of Southern California at 3:41 a.m., closing out a 167-day stay in space.
After more than five months in space, four astronauts on a mission known as Crew-11 are about to cut their mission short and return to Earth.
In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless "microgravity" conditions aboard the International Space Station, but the dynamics of virus-bacteria interactions differed from those observed on Earth.
All four Crew 11 fliers looked healthy and in good spirits on a space-to-ground television broadcast of the change of command ceremony with no indication of which astronaut may have experienced the undisclosed medical issue that triggered Crew 11's early departure.
