ExoMars (Exobiology on Mars) is a European-led robotic mission to Mars currently under development the European Space Agency (ESA) with collaboration by NASA. Since its inception it has gone through several phases of planning with various proposals for landers, orbiters, launch vehicles, and international cooperation planning, such as the 2009 Mars Exploration Joint Initiative (MEJI) with the United States. As of 2011, an ExoMars orbiter examining trace gases and a short-life static lander test is planned for 2016, and one rover — ExoMars rover — for 2018.
