A launch vehicle issue has delayed the launch of NASA's Mars 2020 mission to the end of this month. NASA announced late Tuesday that the launch of the Mars rover mission, previously scheduled for July 22, will now be no earlier than July 30 in order to give engineers time to study "off-nominal" data from a liquid oxygen sensor line during a wet dress rehearsal of the mission's Atlas 5 launch vehicle last week. This is the third delay for the mission, originally scheduled for launch July 17. NASA said they have extended the launch period of the mission by four days, through Aug. 15, and are studying the ability to extend it further, if needed.
