On Dec. 4, NASA announced plans for a robust multi-year Mars program, including a new robotic science rover based on the Curiosity design set to launch in 2020. The planned portfolio includes the Curiosity and Opportunity rovers; two NASA spacecraft and contributions to one European spacecraft currently orbiting Mars; the 2013 launch of the Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiter to study the Martian upper atmosphere; the Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission, which will take the first look into the deep interior of Mars; and participation in ESA's 2016 and 2018 ExoMars missions, including providing "Electra" telecommunication radios to ESA's 2016 mission and a critical element of the premier astrobiology instrument on the 2018 ExoMars rover. With InSight, there will be a total of seven NASA missions operating or being planned to study and explore our Earth-like neighbor.
The 2020 mission will constitute another step toward being responsive to high-priority science goals and the president's challenge of sending humans to Mars orbit in the 2030s.
What is interesting is that the "multi-year" plan discusses putting human in "orbit" around Mars in the 2030s. I cannot imagine we would send humans all that way just to take pictures from above. I think robotic missions can do that just as well. We need humans on the surface.
I was also surprised to see NASA contributions to ExoMars after the space agency pulled out of the mission earlier this year because of funding difficulties. Maybe NASA found funds, since it now has plans to support ExoMars and build another Mars rover, though the ExoMars mission was to include an orbiter and rover. Here is what NASA originally planned to do, which can still be found on its website here:
The ExoMars/Trace Gas Orbiter mission was a joint mission proposed by the European Space Agency (ESA) and NASA. This mission was proposed as the first in a series of joint missions to Mars for ESA and NASA. The two space agencies signed the Mars Exploration Joint Initiative agreement in 2009. Under the former proposed plan, NASA would have supplied the launch vehicle, four science instruments, and a communications system. This joint mission is not currently in NASA’s Mars Exploration Program plans. See information on ESA’s ExoMars mission: http://exploration.esa.int/.
After NASA has walked away from ExoMars, our European friends reached out to Russia for support. Under a new agreement, Roscosmos with provide the European Space Agency with two launch vehicles. The Voice of Russia shared more:
The Naples meeting was crucial for Russian space
research as it was to approve the ExoMars mission deal between ESA and
Russia’s Roskosmos space agency. The project has been approved and the
deal will be sealed November 27.
Thus, Russia got
another chance to explore Mars, five years after the Phobos mission
failure. The first phase of the ExoMars mission is planned for 2016 and
Russia’s Academy of Sciences has already begun research to design
equipment for the Trace Gas Orbiter
robotic orbit carrier which includes ACS spectrometers and the FREND
neutron detector to study water distribution on the Mars surface. It
also includes the EDL
demonstrator module to exploit the entry descent and landing. Russia is
also expected to contribute its Proton carrier rocket to the project.
The
second ExoMars phase will be the launch of the Pasteur rover scheduled
for 2018. Russia is providing a carrier rocket and a landing platform
with research equipment as well as two gadgets for the rover.
