Expedition 43 was the 43rd expedition to the International Space Station. It commenced on 11 March 2015 with the undocking of Soyuz TMA-14M, returning the crew of Expedition 42 to Earth and ended with the departure of Soyuz TMA-15M on 11 June 2015.
The Expedition 43 crew spent an extra "bonus month" on board pending investigation of the Progress M-27M cargo spacecraft failure. On June 8, 2015 ISS adjusted its orbit to move to a safe distance from a piece of orbital space debris.
This expedition also used the ISSpresso machine and tested a special cup designed to be drunk from in microgravity by using capillary flow. This was a further development of a zero gravity cup invented by astronaut Donald Pettit and tested on ISS in 2008. The new zero g coffee cup idea was further developed by a Fluid physicist at Portland State University among others.
