ars technica: Under the Obama administration's guidance, NASA has established Mars as a goal for human spaceflight and said that astronauts will visit the red planet by the 2030s. by Eric Berger
'However, a growing number of critics say the agency’s approach is neither affordable nor sustainable. On Thursday, Griffin, administrator of NASA from 2005 to 2009, joined those critics. The United States has not had a serious discussion about space policy, he testified, and as a result, the space agency is making little discernible progress. NASA simply cannot justify its claims of being on a credible path toward Mars, he added.
'“To quote my friend and colleague Jim Albaugh, the now-retired CEO of Boeing Commercial Aircraft, the current administration’s view of our nation’s future in space offers no dream, no vision, no plan, no budget, and no remorse,” Griffin said during a hearing of the House Science Committee. “We must remedy this matter with all deliberate speed.”
'The Republican chairman of the Science Committee, Lamar Smith of Texas, echoed those concerns in his comments, saying that under President Obama, NASA does not seem to be taking a serious approach to human exploration. The hearing comes at a critical time for NASA, now two months into the last year of President Obama’s second term and with a new administrator likely to replace Charles Bolden in 2017. Republicans in Congress have made it clear they do not favor the president’s plan to send astronauts to visit a fragment of an asteroid near the Moon and an eventual journey to Mars.'
