NASA now is targeting launch of the Parker Solar Probe no earlier than Aug. 6, 2018. Additional time was needed to evaluate the configuration of a cable clamp on the payload fairing. Teams have modified the configuration and encapsulation operations have continued. Teams also have successfully repaired a leak in the purge ground support tubing on the third stage rocket motor, which was discovered during final spacecraft processing late last week. The satellite will launch on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida.
