Howdy. This is your Wayward Plane speaking.
I’m getting A LOT of last-minute inquiries about the Parker Solar Probe launch, and since I expect to be largely unavailable to answer inquiries over the next two days (I’m attending the NASA Social!) here’s the most recent information of which I’m aware:
Parker Solar Probe will be launching on a ULA Delta IV Heavy from SLC-37B at Cape Canaveral Air Force Station. Launch window opens on Saturday, August 11, 2018 3:33 AM EDT (local time) and will remain open for 65 minutes. Weather reports say that we are currently 70% go for launch. If the launch fails to happen at that time, the backup dates are Sunday, August 12 at 3:31 AM, and Monday, August 13 at 3:29 AM.
My best advice for launch viewing is the SR-401 Viewing Stands in Port Canaveral. Drive east on SR-401 toward the CCAFS gates; before you reach the gates, you will encounter uniformed officers who will direct you to parking. Plan on arriving at least a couple of hours early. Exploration Tower VIP Launch Viewing is also on sale is now SOLD OUT. SR-401 should provide you with an excellent view of the launch.
If you can’t make it to either of these places, any location in or around the Space Coast with a clear-ish view toward Cape Canaveral Air Force Station should allow you to view the launch as it ascends. Stay safe, obey any & all local law enforcement, and enjoy the show!
May your journey be nominal and your mission successful,
Wayward
*** NOTE for those finding their way to this post via Internet search: As of 12 April 2019, there are strong indications that Route 401 may not be open for future launch viewing, on the request of Brevard County officials. Pay close attention to official sources of information for further updates, and plan to use an alternate viewing location for launches after this time.
