Massive shout-out to Brian, Jeff, Mark, Mike, Rob and Steve without whom none of this would have been possible
Checklists have been added to the timeline for the countdown. There are over 400. A blue line approximates where the countdown checklist item has been completed. the checklists are placed in the order were in documents S0007.200 and S0007.500
2 post launch to orbit checklists are used. The following might help with your understanding of what is occurring: (courtesy Mark)
“102 102, we are in Auto”
Ferguson is verbally confirming that both the PASS (primary computers) and the BFS (backup computers) switched to the first stage ascent trajectory display know as Major Mode “102”. He also confirmed that the flight control system was in “Auto”.
“Dump has started”
This is a confirmation that the orbital manoeuvring system engines are firing. This “OMS Assist” engine burn is really considered to be a propulsive “dump” of propellants - this helps increase performance
"EVAP OUT" refers to Flash Evaporator Out Temperature. During first stage the orbiter relies on residual cooling from the ground support equipment. There is enough “thermal inertia “ to last for the duration of first stage. This is a good thing since the FES (Flash Evaporator System) won’t work until you have enough altitude - and thus low pressure - to allow for efficient evaporation. At SRB sep the FES is activated by the general purpose computers, it should be working effectively by T+3 minutes. At that time Sandy calls out that the Evap Out T is coming down. She checks that Temperature by looking at a meter on the forward panel above Fergy’s head.
All the stuff with the asterisk borders refers to non-nominal procedures. So none of them were used on this launch.
Everything on the card, including the off nominal stuff, is written in order based on the timeframe it would be relevant.
Roll to Heads up occurs at a velocity of MACH 13.2 (aka 13,200 feet per second) - this is usually at approximately 5 and half minutes into the flight.
What the card is saying below that line is, if you had a problem requiring the PLT (Hurley) to manually throttle the engines, then he would also have to manually shut all the engines down at a velocity of 25,700 feet per second (Mach 25.7). It’s just a reminder - if he does it exactly at that velocity, then the time it takes for the engines to shutdown (thrust decay) should result in a nearly nominal MECO velocity of 25,819.
Post orbit checklists are used.
Video is HD and SD and is as near real-time through to orbit insertion.
Was up this same time 10 years ago rolling into Orlando from Iowa after a 24 hour drive to hop on a bus to KSC to view the launch. Will never forget. Thanks for this!
welcome JC
La creme de la creme LM5! You are the space chef for us thank you so much!
Wow, thank you!
I was out at the river watching this when I was 5
I was there; right by the Countdown Clock during the launch! You can see the back of my head and a white shirt.
So jealous
@@lunarmodule5 You're allowed that! But believe me - it took a lot of work, organization and money to be there. I don't regret the effort one bit. My first press accreditation was refused, believe it or not. I had to hastily arrange a reference with Radio Network New Zealand to get in - I had contacts there that owed me. It took several emails and a couple trans-pacific calls to arrange it. Phew!
Isn't that Shuttle beautiful! I so wish I'd made it to a launch. But will experience it here.
Grew up with the shuttles! Used to rarely see the launch from my backyard lol but we always had our tv on :) Miss those days
I was on the bus headed to the space center during this time of morning. 3:00 am.
Seriously awesome job! Thanks so much!
You're very welcome!
Looking forward to this! :) It's amazing to think it's been 10 years since I saw this in person! Can't wait!
Same here. Flew out from Kentucky to see it. Only 11 at the time.
Thanks LM5. Awesome job putting this together. Top man.
Alright, playtime’s over - let’s get serious.
Thank you for posting. Brings back great memories when my wife and I would enjoy the display of power of a shuttle launch live on the space coast. I do miss this type of coverage that is absent with today's launch converages. Love hearing the launch controllers going over the different steps as well the launch commentary. I guess it shows my age that I enjoy this type of commentary more than what we have been seeing with the latest crew launches to the ISS from SpaceX. I guess it is more cheering and rah rah vs all of the great information that is shared with the viewer with the shuttle launches. Just my opinion.
Can’t wait!
Thanks for upload..! ❤️
You're welcome 😊
This is great! Thanks again, LM5. This time, I’m actually off work and can enjoy it completely
Great stuff Mike - enjoy
I was on a tour bus to watch the launch at 4:30am on July 8,2011. Viewed it from the KSC Visitor Center… thought for a couple hours the rain was going to scrub the launch but despite a last minute hold I did see Atlantis rise into the clouded skies, my first ever manned space launch! I’m glad that I was there to see Atlantis take to the skies into space for the final time!
godspeed
Space shuttle atlantis. The final launch and then retirement.
I was there for the last launch. I was at the cause way.
Just wishing it had been more sunny or less overcast for the final launch day.
I wonder if Hugh Harris was invited back to launch control to be there for the end. For a while now I’ve been watching, really listening, to the STS-1 mission on this channel, thinking back to what life was like back then at the very beginning. The reason being is because I wasn’t even 1 years old when STS-1 launched and lived through the entire program. The voice of Harris just brings me back to my childhood days of this winged spaceship and brave astronauts reaching for the stars.
He is in launch control and is interviewed by the then PAO on this video
@@lunarmodule5 😊 Glad he was there
WOW!!!!!!!1 Just realized my name is in the credits! nice!
Of course it is matey!
Poor guy doing voice for launch sounds like he got no sleep and lost his notes
And don't forget to order new HD box for future viewing
LMAO, tech keeps improving and its fun to see what just 12years has done!
Will miss the shuttle
My grandparents drove down to Kennedy to see the launch, but by the time Atlantis went up they were still in traffic.
9:32:16 start
All hail Atlantis
how did you get the popup checklists during the countdown and where can i find them??
Lift off of Atlantis and the clock has started
We are on our way
Off she goes for the last time
After 40 years, the final space shuttle progam launch Atlantis, making a cosmetic journey through outer space and the international space station.
(George Diller - Host of the final Space Shuttle launch Podcast)By the way the entire audience at the launch press site was on time to view this!
This is no longer the final crewed launch from American soil.
Atlantis
Prince of the stars
I did want to be an Astronaut and be in the space shuttle
where did u find the checklists??
Sent to me by someone who has a collection of STS items
@@lunarmodule5 darn. id love to get my hands on thoes. nasa has flight checklists but they dont include all of them.
@@PolarPenguin526 if you contact me at lunar_module_5@yahoo.co.uk I will send you what I have
Nice effects, but you can't have the moon spin like that...
?
The beginning? You do realise that's satire?
Это не Луна а Земля они на луну а на МКС они С Земли стартуют а не с луны
