NASA Can't Afford Senate's Timeline for Solar Probe

摘要

While some members of Congress would like to see NASA launch the Solar Probe Plus mission by 2015, agency offi-cials say they lack the funding needed to finish and fly the solar spacecraft before 2018.rn"This is a $1.2 billion program," said Richard Fisher, heliophysics division chief for NASA's Science Mission Directorate here. "We don't get enough budget be-tween now and 2015 to launch it. That was an idea, but it's a concept; it isn't a real possibility."
