COUNTDOWN AND LAUNCH TIMELINE
HR/MIN/SEC
EVENT
– 04:59:59
The Dragon Capsule aligns its inertial measurement units and is configured for launch
– 04:30:00
The Crew Dragon hypergolic fuels for reaction control thrusters and the superdraco abort motors are pressurized for flight
– 04:15:00
The Crew hears a weather briefing before they suit up
– 04:05:00
The Crew is officially handed off from NASA to SpaceX, which is bit of a formality signifying the astronauts are officially in SpaceX’s hands
– 04:00:00
The crew suits up at Kennedy Space Center’s Neil Armstrong Operations and Checkout Building
– 03:22:00
The crew leaves the building and gets into the NASA and SpaceX’s Tesla Model X crew transportation vehicles. In other words, the crew gets suited up and ready to go in just 38 minutes, which is faster than most of us get ready for work in the morning
– 03:15:00
The crew departs the Ops and checkout building and heads the 13.6 km (8.5 miles) to historic Launch Complex 39A
– 02:55:00
The crew arrives at the pad. Since they will travel about 13.6 km in 20 minutes, it means they’ll only average around 40 km/h COME ON, they should turn on ludicrous mode and really put on a show!
~ 02:40:00
The crew will do the ultimate walk across the Crew Access Arm, hopefully in slow mo so we get some awesome cinematic footage
– 02:35:00
The crew enters the Dragon
– 02:20:00
Communications check between the crew and the ground
– 02:15:00
The seats rotate up putting the astronauts more on their backs and closer to the screens and controls
– 02:14:00
They check for leaks in the suits and verify they’re good to go
– 01:55:00
The hatch is closed up and the ground support crew leaves the pad
– 01:10:00
The exact state and location of the International Space Station is uploaded to the Dragon Capsule
– 00:45:00
The Go / No-Go Poll is taken to fuel up the vehicle
– 00:42:00
The Crew Access Arm is retracted
– 00:37:00
Dragon launch escape system is armed, which gives the crew the ability to abort from the rocket if there were a problem during fuel up or during ascent
– 00:35:00
The RP-1 rocket fuel and the cryogenic liquid oxygen begin loading into the first stage of the rocket and RP-1 is loaded into the second stage
– 00:35:00
1st stage LOX loading begins
– 00:16:00
The Liquid oxygen begins filling the second stage
– 00:07:00
Falcon 9 begins engine chill prior to launch
– 00:05:00
Dragon transitions to internal power
– 00:01:00
Command flight computer to begin final prelaunch checks
– 00:01:00
Propellant tank pressurization to flight pressure begins
– 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




LAUNCH, LANDING, AND DRAGON 2 DEPLOYMENT
HR/MIN/SEC
EVENT
00:00:58
Max Q (moment of peak mechanical stress on the rocket)
00:02:30
1st stage main engine cutoff (MECO)
00:02:34
1st and 2nd stages separate
00:02:36
2nd stage engine starts
00:07:12
1st stage entry burn
00:08:43
2nd stage engine cutoff (SECO-1)
00:08:45
1st stage begins its landing burn as it prepares to land on the autonomous spaceport drone ship
00:09:09
1st stage landing
00:12:00
Crew Dragon separates from 2nd stage
00:12:46
Dragon nosecone open sequences begins
00:49:06
After a few check outs of the draco reaction control thrusters and a few pointing maneuvers, there’s a phase burn of 16.11 m/s to align the orbits of the Dragon and the international space station
09:44:44
There’s another phase adjustment burn
11:10:15
The Dragon Capsule performs a 44.2 m/s burn using its draco thrusters to boost its orbit closer to the International Space Station
11:55:01
There’s another burn, this time of 57.89 m/s which circularizes the orbit
17:40:24
After a few mid course burns, the Crew Dragon is approaching the 400m keep out sphere and requires a Go / No-Go poll from Mission control to continue
17:50:24
The Dragon Capsule enters the keep out sphere and hits Waypoint Zero which is 400m below the ISS
18:15:24
The Dragon Capsule arrives at Waypoint 1 and holds approximately 220m away to align to the docking axis
18:51:24
A final Go / No-Go Poll is given for docking
18:56:24
The Dragon Capsule arrives at Waypoint 2 which is only 20m away and gets placed into a short hold
19:01:24
The Dragon capsule departs Waypoint 2 and goes in for the docking
19:06:24
the Dragon Capsule has contact and capture with the International Space Station
19:06:25
A big sigh of relief from the crew and Mission Control, the Dragon is docked and the crew has officially arrived at the International Space Station!

While watching a live shot from the cape this morning on the news I was reminded of Apollo 12.
There was thunder and lightning in the news shot.
Apollo 12 was struck by lightning during the launch and limped to earth orbit.
Amazingly, everything came back on line and they were cleared to go to the moon and the mission was successful.
