So, now that the shuttle era of American space exploration is over, and we're looking both forward and back, who do you think rank among the the Top 10 space explorers of all time?
Yuri Gagarin? John Glenn? Story Musgrave? John Young? Robert " Hoot" Gibson? Dick Covey? Neil Armstrong? Alan Bean? Jim Lovell? Al Worden?
An online magazine called Txchnologist and sponsored by General Electric has a list.
Check out their Top 10 HERE.
And build your own list in our comments section. We'll try to tally the votes and publish our our Flame Trench Top 10.
Thanks in advance for your input. Because it's all up to you.
