krou writes "The Guardian is reporting that NASA is quietly revising its internal estimates of a 2018 launch for its Ares V rocket. Although publicly the date given for the launch was 2020, the internal launch date was set for 2018. The shift in dates seems to be linked to 'growing budget woes,' and 'engineers say that means the public 2020 date to send humans back to the moon is in deepening trouble.' NASA administrator Mike Griffin blamed the White House, and the previous Bush administration, saying funding for Ares V and other projects fell from $4bn through 2015 to just $500m. 'This was to be allocated to early work on the Ares V heavy-lifter, and the Altair lunar lander. With only a half-billion dollars now available, this work cannot be done.'"
