SLS Will Never 'Back Up' Commercial Crew, Jim Muncy, Space News
"One such argument is the claim from both houses of Congress that the funding for the Space Launch System (SLS) -- which increases from the 2012 level -- is too small to enable the SLS to launch the Orion Multi-Purpose Crew Vehicle (MPCV) as a backup for commercial crew services. Some even suggest that NASA is putting too much money into the legislatively stipulated primary means of carrying astronauts to and from the international space station (commercial crew) and therefore shortchanging the backup (SLS). Of course, NASA is spending nearly four times as much on Orion and SLS as it is on commercial crew, so the argument appears lopsided."
