New NASA rocket faces delays, Orlando Sentinel
"Lori Garver, leaving NASA after four years as deputy administrator, said NASA and Congress long have oversold the agency's ability to build the rocket, called the Space Launch System, and its Orion capsule on an annual budget of roughly $3 billion. "It's very clear that we could have slips of a year or two," said Garver, referring to both the 2017 launch -- which won't have a crew -- and the first planned flight of NASA astronauts aboard the SLS rocket in 2021. "People are more optimistic than ... reality," she said in an interview with the Orlando Sentinel."
"So what you've got is a beast of a rocket, that would give you all of this capability, which you can't build because you don't have the money to build it in the first place, and you can't operate it if you had it."
