Herschel starts to ROCK. At the moment this is the most distant human-made object I've seen with my own eyes ;)
Fortunately someone in ESA does some *real* science...
Solid state tunnel junction can cool "payload" to sub-Kelvin temperatures. This would be much more convenient than for example helium3-helium4 mixing. Proposed use for cooling sensors on spacecraft - could extend lifetime of satellites like ESA's about to switched off Herschel almost indefinitely.
In terms of country based quotations ("Most scited countries") I cannot access space science, only Geosciences, Immunology, Material Science, and Psychiatry & Psychology.
But when I first saw the list of countries at the left under "Impact in Science" I saw Argentinia was on top, and USA was on last position. Yes, I was surprised, until I realised that is was just an alphabetical order.
Did you see the same list?
data a bit old ....
newer data (but less well presented) at http://sciencewatch.com/
there you can also read:
"The 20th century was largely dominated by the US as a major powerhouse of scientific research and innovation, with 40% of the papers indexed in the Web of Science fielded by US scientists in the 1990s. By 2009, that figure was down to 29%. The US now struggles to keep pace with increased output from Europe and Asia."

Interestingly, Space Science is the only field in which my country has positive "Impact vs. world" value (even more interestingly as we don't even have a proper national space agency)...
this might also be an indication / point to an issue with their data concerning space science publications ... quite surprising indeed that all Europeans are doing so well in this field
