With #Nauka dock scheduled for 9:24 AM EDT - based on the #Pirs undocking telemetry, we should see SARJ lock at 7:29 AM and Pitch Up beginning 8:19 AM. Will find out soon! Alas, that means pitch up will be in ISS eclipse so we won't see that happening @Space_Station.
I'm sure the priority is to have #Nauka dock during @Space_Station daylight and 9:24 AM EDT is about 7 minutes before eclipse - so that makes sense.
Good morning everyone! #ISS crew is now back awake and is just having their morning DPC (daily planning conference). Seems like the activities for undocking of #Pirs will actually take place today! #Exp65 #MLM #Nauka
Russian #ISS crew members are also doing some tasks today to prepare for a potential contingency EVA if that becomes necessary after #Pirs undocking and before #Nauka docking.
Also the OPM (optimal propulsion maneuver) that actually did not take place yesterday will now take place today affecting the Ku-Band capability of the #ISS.
On board the #ISS many activities regarding #Pirs undocking have been canceled indicating that the undocking tomorrow based on the current status of #MLM #Nauka has been canceled. #unconfirmed #Exp65
Ok so the OPM (optimal propulsion maneuver) to reorient the #ISS to the undocking attitude for #Pirs is still on schedule! MCC #Houston reminded @Aki_Hoshide to close the window shutters for that during morning DPC (daily planning conference)
Since I am getting many retweets and likes on that tweet I like to remind everyone that this is just what I think I understoond on the translation loop during the morning DPC on the #ISS livestream. Let's wait everyone and see what the day holds up for us.
Good things come to those (modules) that wait. It's LAUNCH DAY for the #Nauka science lab! The long-delayed module finally gets its time to shine. Liftoff is set for 14:58:21 UTC / 10:58:21 EDT form Baikonur

With less than an hour to launch, let's take a trip through #Nauka's long history. There's a reason it's lovingly referred to as the "long suffering module."

#Nauka was originally a back-up to Zarya, in case that critical first ISS module was lost in a launch failure. Nauka, or FGB-2 as it was called then, was nearly complete when Zarya successfully launched in Nov. 1998. 2/x
Upon multiple request I will try to recreate the construction of the #ISS with the recent released @LEGO_Group model in this thread (if you find any errors please let me know):
On November 20th 1998 the first #ISS module #Zarya aka #FGB was launched from #Kazakhstan with a #ProtonK rocket. It was built in Russia but funded by @nasa but operated by @roscosmos. Its purpose is cargo storage
