Eugene Cernan, the last astronaut to walk on the moon and a co-author of the April letter to Obama, spoke of the new plan in harsher terms, calling it a "blueprint for a mission to nowhere".
He said the new plan lacked focus, is short on details, and does not commit enough money to support human space exploration. He expressed concern that the development of a heavy-lift rocket needed for exploring space beyond low-Earth orbit – which is deferred until 2015 under the new budget – might never come to pass.
"Now is the time to overrule this administration's pledge to mediocrity," he said.
Remember Obama's pledge to restore science to its rightful place?
"We will restore science to its rightful place, and wield technology's wonders to raise health care's quality and lower its cost," said Obama.
Empty words from and empty suit.
