This is interesting. If you look at the memo that broke down the conversion of NASA's Constellation Program back to English units, they mentioned that metric would persist in certain areas, one of them being the upcoming international moon missions. So that sets a precedent for joint projects to use in metric units.
This just further underlines the foolishness and short-sightedness of NASA backsliding on metrication in other areas.

Check this out: http://www.time.com/time/health/article/0,8599,1903571,00.html Latest from Time magazine: Apparently NASA wants to partner with the ESA (European Space Agency) on the Mars mission. The article also mentions a potential union of the two agencies by 2016. A recently re-imperialized NASA and a metric ESA. Should be interesting. Remek
