Watching Boeing’s Starliner launch tonight
At 6:54 pm (Eastern) tonight a ULA Atlas-5 rocket will launch Boeing’s manned Starliner capsule on its second attempt to complete an unmanned demo mission to ISS.
NASA’s live coverage will begin at 6 pm on NASA-TV. I have embedded the youtube channel of this live stream below the fold. At the moment the station is broadcasting its regular NASA propaganda (some of which is actually informative). The launch’s actual coverage will begin at 6 pm (Eastern), and continue until the spacecraft is successfully inserted into orbit. Further coverage of the flight, including docking with ISS, will be as follows:
9 pm (Eastern) – Post launch press conference (time subject to change).
May 20
3:30 pm (Eastern) – Coverage begins of the rendezvous and docking to ISS, with the actual docking scheduled for 7:10 pm (Eastern).
May 21
11:30 am (Eastern) – Coverage of the opening of Starliner’s hatch, scheduled for 11:45 am (Eastern).
Boeing’s first attempt to complete this mission in December 2019 was forced to return to Earth before docking with ISS because of numerous software issues. Then, an attempt to launch again in August 2021 was scrubbed because numerous valves in the capsule’s service module failed to operate properly during the countdown. The company had to return the capsule to the factory to replace that service module as well as make some changes to the valves to make today’s launch possible.
For Boeing, these delays and fixes have cost the company a lot of money, since its contract with NASA is fixed price. This second demo mission will cost Boeing about $400 million, but even worse, the delays meant that SpaceX got some of the business with NASA and other private customers that it might have gotten had Starliner been operational.
Update: NASA has cut off coverage of the docking on the channel I had embedded previously. I have now embedded an active live feed.
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

Watching now.
Fingers crossed. Hope they have a successful flight. I think the bar for success is pretty high at this point. If there are issues, I doubt it will be the Atlas 5 is the issue.
Also, maybe they changed this a while ago, and I never caught it.. I am used to “T minus (time)”. They are using “L minus (time)”
Is this new?
As of 19:27 Eastern Daylight Time, successfully inserted into orbit. Launch appeared to be nominal except for slight “over performance” by First Stage, which was corrected by Second. On to ISS!
sippin_bourbon: L minus is a term ULA uses, but I can’t remember what makes it different than T minus, which refers to actual liftoff.
Sippin_bourbon,
There are two times in use- the T-minus which is the time till liftoff which has built in holds and can stop, and L-minus is the real time of lift-off as is always running. Here is a short video talking about it. It is a good explanation that the T-minus is event driven and L-Minus is the actual time.
It occurred to me as I watched this, “You’re watching the last hurrah of an obsolete technology” as nothing was recovered.
I don’t know if it was just a different broadcast protocol, but the media coverage seemed a little less sparkling than what I associate with SpaceX. The video seemed a lot less crisp and the on-air commentators were less engaging.
Of course I have to admit I am completely smitten with the blonde lady engineer who has been with SpaceX coverage since the beginning. What a charming and intelligent woman!
Okay. I get it.
T for time line based events.
L for specific launch time.
This implies they have two different clocks running concurrently.
