How Does NASA's Ban on Russian Contact Affect Curiosity?
On Wednesday, the political crisis in Crimea spilled into the space program, as NASA circulated an internal memo stating that it was breaking off most contact with Russia. The only activities specifically exempted from this ban related to the International Space Station, which raised questions about other NASA-Roscosmos collaborations, particularly the Dynamic Albedo of Neutrons (DAN) experiment on the Curiosity rover, which was provided by Roscosmos and is led by a team of Russian scientists.

Yesterday, I received confirmation from Bob Jacobs, NASA's Deputy Associate Administrator for Communications, that science operations on Curiosity would continue as normal with participation of the DAN team.
"The limitation is in regards to NASA interaction with members of the Russian Federation—official government employees," said Jacobs. "We don't believe the science from Curiosity will be impacted by this guidance."
"The guidance is specific about bilateral meetings and even then it has to involve official members of the Russian government before it's a problem," he added.
The directive applies to all government agencies, not just NASA; each agency will determine what activities are exempted or not on a case-by-case basis; and it is an evolving situation. The unambiguous message is that operations of the ISS are not impacted.
