The International Space Station's (ISS) Expedition 43 begins with the scheduled undocking of Soyuz TMA-14M in March 2015. Three new crew members will arrive shortly thereafter on Soyuz TMA-16M.
Expedition 43 will be commanded by NASA astronaut Terry Virts. His crewmates, all flight engineers, include: Roscosmos cosmonauts Anton Shkaplerov, Yury Lonchakov and Mikhail Korniyenko, NASA astronaut Scott Kelly and European Space Agency (ESA) astronaut Samantha Cristoforetti.
The hexagon (six-sided) shape of the Expedition 43 patch represents the six crew members living and working onboard the orbital outpost.
The International Space Station is portrayed in orbit around the Earth, representing the multi-national partnership that has constructed, developed, and continues to operate the ISS for the benefit of all humankind.
The sunrise marks the beginning of a new day, reflecting the fact that we're at the dawn of our history as a space faring species. The moon and planets represent future exploration of our solar system, for which the ISS is a stepping stone.
Finally, the five stars honor the crews who have lost their lives during the pursuit of human spaceflight.
