To the stars through hardships

As a quick followup to the Commodore's blog entry about today's anniversary of perhaps mankind's greatest achievement,  I'd just like to remind everyone about the astronauts and cosmonauts that gave their lives in the line of duty so that we may still dream of reaching for the stars.  If you are so inclined, perhaps put some of these names into Wikipedia and find out a little more about the extraordinary lives they led.  (Info from here)
