Teams require additional time for processing NASA’s Parker Solar Probe spacecraft after discovering a minor tubing leak in the ground support equipment during final processing. The tubing is being repaired, and the spacecraft is healthy. As always, operations take precedence during launch and we needed to cancel media day activities on July 13, 2018. NASA will make every effort to provide updated imagery of the spacecraft prior to encapsulation.Parker Solar Probe is the agency’s mission to touch the Sun. It is scheduled to launch on a United Launch Alliance Delta IV Heavy no earlier than Aug. 4, 2018, from Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida.

ULA conducted a successful initial WDR on Monday, July 2, which focused on “first stage objectives” with fueling of the vehicle’s three 134-foot tall Common Booster Cores, which are powered by a trio of RS-68A cryogenic liquid hydrogen/liquid oxygen burning engines.
Today (Friday, July 6), teams are conducting another WDR, a full blown countdown to a simulated liftoff, aiming “to complete all objectives including second stage tanking,” according to ULA. The rocket’s second stage is powered by a single cryogenic liquid hydrogen/liquid oxygen burning RL10 engine.

@torybruno Any update you can give us on how the 2 WDRs for Delta IV-H went? All good to go?
Good. Yes, good to go
How often is more than one WDR needed, when there's apparently no equipment or procedural failure during a launch campaign to recover from?

Never. This flow scheduled two because this is the first East Coast flight of a D4 with the common avionics suite. That entailed a lot of changes to the ground systems controlling the GSE and the rocket. So, two runs to make sure the bugs were fumigated completely.
Launch slipping 2 more days to Aug 6 according to NASA...https://blogs.nasa.gov/parkersolarprobe/2018/07/18/parker-solar-probe-launch-no-earlier-than-aug-6-2018/
