Colorado astronaut Jack Fischer is back home on Earth after spending 136 days in space.

Fischer, along with two other astronauts, landed near Zhezkazgan, Kazakhstan on Saturday, according to NASA.

Astronaut Peggy Whitson and cosmonaut Fyodor Yurchikjin served with Fischer as members of the Expedition 51 and 52 crews on the International Space Station.

Fischer conducted several experiments during his time in space, including a research on the physical changes to astronaut's eyes caused by a microgravity environment.
