NASA has selected several mission proposals for future missions to Mars. They include missions where NASA is the primary driver, as well as participation by NASA on the ESA's ExoMars project.
Mars Atmosphere and Volatile Evolution mission, or MAVEN: The mission would provide first-of-its-kind measurements and address key questions about Mars climate and habitability and improve understanding of dynamic processes in the upper Martian atmosphere and ionosphere. The principal investigator is Bruce Jakosky, University of Colorado, Boulder. NASA's Goddard Space Flight Center, Greenbelt, Md., will provide project management.The Great Escape mission: The mission would directly determine the basic processes in Martian atmospheric evolution by measuring the structure and dynamics of the upper atmosphere. In addition, potentially biogenic atmospheric constituents such as methane would be measured. The principal investigator is Alan Stern, Southwest Research Institute, Boulder, Colorado. Southwest Research Institute, San Antonio, will provide project management.
And several others.
A mixed crew of Italian and French researchers will be spending a year in the ESA's Concordia Station, located in Antarctica.
While final details are unclear, it looks like financial grumblings may have scuttled (for now, at least) the ESA's participation in Russia's proposed Cliper shuttle. The United Kingdom will be playing a role in the ESA's ExoMars mission.
Here's a document that outlines the plans for the European Space Agency for the immediate and near-term future. Goals include ExoMars (a robotic exobiology mission to Mars), participation the Russian Cliper shuttle, the medium Vega launcher and more.
While final details haven't shaken out, it looks like the ESA's ExoMars rover has won out over a more elaborate BeagleNet rover mission. Also lost appears to be another chance for the science suite from the Beagle-2 mission to make it to Mars.
The ESA appears to have concluded that the ITAR (International Traffic in Arms Regulations) are too much of a roadblock to see international cooperation on their planned Mars rover...so they will go it alone.
The real question is whether the planned rover will receive sufficient (if any) funding. As with space programs around the world, the budget pinch is being felt.
The ESA is holding a workshop to talk about how to operate on the surface of the Moon and Mars as part of Project Aurora.
