Dextre was launched to ISS in March 2008, and was fully tested and
qualifed for space operations a year later in April 2009. Then what?
There has been a complete absence of any news about Dextre. Has it
ever been used? Is there a problem? Is it getting jealous over all
the press the more photogenic Robonaut is getting?
