I was unable to connect to the link in your first post,Dana
That doesn't surprise me,,,Remember this mission
is still in the planning stage and must be passed by congress and the president.
NASA is NOT one of o'Buma's interest or priorities,,,,OTOH,,,the bum will be out of office by 2020 and hopefully,we might get a
more space friendly president.
The USA has the tech and a success ratio to prove it,,we CAN land a craft on another planet,,,when I look at the European 'Next
Robot to Mars',,,and see that the landing is provided by Russia,,,I cant help but shudder.
One thing I have said for years,,,Technology
will contuie to become better,,,regardless of Polotics.We have some beautiful,new,young,curious minds scattered around the globe...theirs will be the future of mankind in space.
