It's such a long mission and we get to spend so much time in space... we're doing such exciting research. And I don't want to overemphasize the life science research but as a physician the life science research that we're doing is extremely exciting.
I love those who can smile in trouble who can gather strength from distress and grow brave by reflection. 'Tis the business of little minds to shrink but they whose heart is firm and whose conscience approves their conduct will pursue their principles unto death.
