Updates: NASA's SpaceX space station resupply mission launched from KSC on Saturday
---
Update: SpaceX launched this mission at 2:20 p.m. ET on Saturday, November 26 from pad 39-A at Kennedy Space Center in Florida.
Update: SpaceX scrubbed Tuesday's NASA CRS-26 space station resupply mission due to unfavorable weather. The next launch attempt is at 2:20 p.m. ET on Saturday, Nov. 26. Weather conditions are predicted to be 70% "go."
Follow live updates as SpaceX targets 2:20 p.m. ET on Saturday, Nov. 26, for the launch of a Falcon 9 rocket and Dragon capsule from Kennedy Space Center in Florida.
It marks SpaceX's 26th resupply flight under contract from NASA, also known as CRS-26. It will be the 52nd launch from Florida's Space Coast this year.
After liftoff from pad 39A and a flight toward the northeast, Falcon 9 will target a drone ship landing in the Atlantic Ocean.
Space Force forecasters have predicted a 70% chance of weather conditions remaining favorable for today's launch attempt.

Updates from Saturday's event below:
Dragon separation
2:32 p.m. ET: The SpaceX cargo Dragon has separated from the Falcon 9 upper stage. It now has an hours-long trip in orbit to chase down the space station. An autonomous docking attempt is expected Sunday morning around 7:30 a.m. ET.
The Falcon 9 has landed
2:28 p.m. ET: The Falcon 9 first stage booster has landed on a drone ship in the Atlantic Ocean.
Liftoff!
2:20 p.m. ET: SpaceX launched a Falcon 9 and Dragon capsule from Kennedy Space Center in Florida for NASA's CRS-26 resupply mission to the space station. Dragon is set for arrival at the station around 7:30 a.m. EST on Sunday, Nov. 27.
Under 10 minutes
2:10 p.m. ET: With less than 10 minutes until liftoff SpaceX reports that weather has improved to an 80% chance of "go" conditions for launch. Here's a list of what remains in the countdown:
00:07:00 Falcon 9 begins pre-launch engine chill
00:05:00 Dragon transitions to internal power
00:01:00 Command flight computer to begin final prelaunch checks
00:01:00 Propellant tanks pressurize for flight
00:00:45 SpaceX Launch Director verifies go for launch
00:00:03 Engine controller commands engine ignition sequence to start
00:00:00 Falcon 9 liftoff
"Go" for fueling
1:43 p.m. ET: The SpaceX launch director has given the "go" to proceed with the fueling of the Falcon 9 ahead of today's launch attempt. Liftoff is slated for 2:20 p.m. ET from Kennedy Space Center's pad 39-A.
One-hour to launch
1:20 p.m. ET: Now within one hour to liftoff. Today's CRS-26 mission has an instantaneous launch window which means it must launch precisely on time or delay until another day. In about 20 minutes we expect the SpaceX launch director to conduct a poll to determine whether or not to proceed with fueling the Falcon 9 ahead of today's launch attempt.
Some clouds are building off of the coast to the East. We'll have to wait and see if those pose a problem or not over the next hour. Stay tuned.
Welcome back to live coverage
12:50 p.m. ET: Liftoff of NASA's SpaceX CRS-26 ISS resupply mission is slated this afternoon for 2:20 p.m. ET from LC-39A at Kennedy Space Center.
Yesterday, the Space Force's 45th Weather Squadron predicted weather conditions to be about 70% favorable for an on-time launch attempt this afternoon. Today's window is instantaneous which means if SpaceX is unable to launch today it will have to delay the mission until a later date.
Stay tuned as we bring you all updates throughout today's countdown.
Updates from Tuesday's event below:
Next launch attempt:
NASA and SpaceX will retarget the launch of this CRS-26 mission for liftoff at 2:20 p.m. ET on Saturday, Nov. 26, from LC-39A at Kennedy Space Center. The weather outlook for that attempt is currently 60% "go."
Scrubbed
3:51 p.m. ET: SpaceX has scrubbed today's CRS-26 mission due to poor weather conditions.
Inside 10 minutes
3:44 p.m. ET: Now inside 10 minutes to launch. There are still some red, or "no go," weather rules, but NASA and SpaceX are hoping for that to clear in time for the instantaneous launch window at 3:54:03 p.m. ET. Stay tuned.
"Go" for fueling
3:16 p.m. ET: The SpaceX launch director has given the go to proceed with fueling the Falcon 9 ahead of today's CRS-26 launch attempt at 3:54 p.m. ET from LC-39A at KSC.
Inside one hour
2:54 p.m. ET: Now inside one hour to liftoff targeted for 3:54 p.m. ET. Numerous weather launch criteria rules remain red, or "no go," for launch. This includes a rule not to fly through precipitation. SpaceX and NASA continue to countdown.
Keeping an eye on weather
2:25 p.m. ET: Good afternoon. SpaceX and NASA are counting down to the CRS-26 ISS resupply launch from LC-39A at Kennedy Space Center this afternoon at 3:54 p.m. ET. SpaceX did recently post on its Twitter account that "teams are keeping an eye on weather which is 10% favorable." Right now there are dense clouds and rain over the spaceport. We'll share all updates as we get them. Stay tuned.
