Two launches scheduled for tonight, 27 minutes apart
The numerous launch scrubs this past week has created an unprecedented situation tonight, two orbital launches scheduled only 27 minutes apart from two different East Coast spaceports.
First Northrop Grumman will try again to launch its Cygnus cargo freighter to ISS from Wallops Island, Virginia, with the launch scheduled for 9:12 pm (Eastern). The first launch attempt last night was aborted 2:21 seconds before liftoff “after receiving off-nominal data from ground support equipment.”
Second, SpaceX will try to launch two Air Force GPS satellites from Cape Canaveral, Florida, with the launch scheduled for 9:43 pm (Eastern). This launch has been delayed several times because of the repeated launch scrubs of ULA’s Delta 4 Heavy rocket, attempting to launch a military reconnaissance satellite. ULA’s launch had priority for the range, but with it delayed due to the investigation over the T-7 second launch abort on September 30th, the SpaceX’s GPS launch moves up in line.
The first will be live streamed on NASA TV, the second by SpaceX. I have embedded the live streams for both below the fold.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Wallops. Clear skies this evening. 4mph winds predicted.
Cape. 90-100% cloud cover, minimal chance of rain. 5-6 mph winds.
I do not know how far down range the weather must remain favorable.
It looks like drone ship recovery so winds and seas must be favorable there as well.
Currently okay for the Cape, according to SpaceX twitter.
I wonder what the contractual arrangements are between USSF and SpaceX insofar as expending boosters. Can USSF demand “Launch at first opportunity, regardless of whether there is the ability to recover the booster or not!”?
Wallops Island launched successfully. I watched it go by down in SE Virginia. Cool. :)
I’m glad I left this up all day, or I would have forgotten and missed it.
Bummer on the SpaceX scrub. I wonder if it takes a huge set of brass balls to scrub at T-2.
Falcon 9 scrubbed for the day. Not sure yet about the issue.
It’s getting worrisome, though. Weather I could understand, but repeated technical bugs on such a mature design? Maybe Elon transferred too many top people to Starship…
I am more concerned that two important national security payloads cannot get off the ground.
There’s an ironical typo ar 12:03, during the Lockheed-Martin promotional material. The word “commercial” is misspelled.
