Space: Not too big for sanctions

An unexpected victim of US sanctions against Russia may be the Nasa space programme. Rebecca Morelle reports.

In July, President Obama matched the EU's latest round of sanctions on Russia over the crisis in Ukraine.

Many of them target powerful people close to President Putin who are some of Russia's richest businessmen, but one unexpected victim may be the US space programme. Nasa scientists have been ordered to suspend collaboration with their Russian counterparts.

So what does it mean for a relationship that has been nurtured since the Cold War? And what are the long-term implications for future space programmes?
