Updates: Watch NASA and SpaceX launch Crew-5 astronauts from Kennedy Space Center

Update: Liftoff of Falcon 9 and Crew Dragon at noon Wednesday, Oct. 5! The launch marks the start of a roughly 29-hour flight to the International Space Station. Read our full post-launch story here.

Watch live as NASA and SpaceX target noon Wednesday, Oct. 5, for the launch of the Crew-5 mission from Florida's Kennedy Space Center with three astronauts and a cosmonaut.

NASA astronauts Josh Cassada and Nicole Mann, Japan's Koichi Wakata, and Russia's Anna Kikina will launch in a Crew Dragon capsule from pad 39A for a six-month mission to the International Space Station. This will mark the first time a cosmonaut flies in Crew Dragon.

If everything goes according to plan, Crew Dragon will arrive at the ISS just before 5 p.m. EDT Thursday, Oct. 6.

Crew Dragon in good orbit

12:15 p.m. EDT: SpaceX's Crew Dragon spacecraft is in a good orbit and on its way to the International Space Station. The capsule and its "trunk" have separated from the second stage, giving way to the crew's 29-hour flight to outpost some 250 miles above Earth. They'll stay there for about six months.

Liftoff of Crew-5!

12 p.m. EDT: NASA and SpaceX's Crew-5 mission is off the pad! The crew of four is now en route to the International Space Station and should arrive there in about 29 hours.

Up next is the first stage booster's landing on a drone ship in the Atlantic Ocean.

T-minus 5 minutes to Falcon 9 launch

11:55 a.m. EDT: Everything is still "go" for liftoff in five minutes. Weather, the Falcon 9 rocket, Crew Dragon capsule, and Eastern Range (clearing boats and aircraft) are all "go" for launch.

Reminder that Falcon 9 will fly exactly 57 seconds after 12 p.m., so keep that in mind.

T-minus 10 minutes, still 'go'

11:50 a.m. EDT: T-minus 10 minutes. Everything's still in the green for liftoff, especially weather. Forecasters are saying conditions are nearly 100% "go" for liftoff at 12:00:57 p.m. EDT.

Falcon 9 fueling underway

11:25 a.m. EDT: Fueling of the Falcon 9 rocket with liquid oxygen and kerosene is now underway. The launch escape system was also successfully armed a few minutes ago. T-minus 35 minutes.

Crew arm retracted, 'go' for fueling

11:15 a.m. EDT: SpaceX's launch director confirms teams are "go" to retract the crew access arm (walkway used by astronauts) from the Crew Dragon capsule. Also good to go for arming the launch escape system and starting fueling at 11:25 a.m. EDT.

Pad teams departing area

Checks complete. Closeout crew is about to leave pad 39A in advance of liftoff at 12:00:57 p.m. EDT. So far, communications, suit, seal, and hatch checks have all passed. No other issues noted.

Next up, the crew access arm at pad 39A will be retracted from the capsule. That will happen between T-minus 42 and 44 minutes.

Crew Dragon hatch leak check OK

10:40 a.m. EDT: Sounds like the hatch leak check went well after a human hair was found in the seal. Still on track for liftoff at 12 noon EDT.

Debris removed from seal

10:35 a.m. EDT: Sounds like a human hair was found in Crew Dragon's hatch seal. Team removed it and will re-test to check integrity. If you're wondering if a tiny human hair can be detected by the system – yup, this is the second time it's happened with a hair specifically.

Debris found in hatch seal

10:25 a.m. EDT: Sounds like teams found a small piece debris in one of the seals in the side hatch. Teams will need to re-open and re-check, but there's still some margin in today's countdown. Stay tuned.

Meet NASA/SpaceX's Crew-5

While we wait, let's meet the astronauts:

>Nicole Mann (NASA, commander): Mann is a Marine Corps F/A-18 pilot and engineer. She will be the first Native American woman to go to space and this is her first mission. She is from Petaluma, California.

>Josh Cassada (NASA, pilot): Cassada, a Navy test pilot and physicist, will also mark his first flight to space today. He is from White Bear Lake, Minnesota.

>Koichi Wakata (JAXA, mission specialist): Wakata is the veteran of the group. The Japanese astronaut will mark his fifth flight today – three on space shuttle, one on Soyuz, and of course Crew Dragon.

>Anna Kikina (Roscosmos, mission specialist): Kikina will become the first Russian cosmonaut to fly on Crew Dragon. She is an engineer and will act as a mission specialist during the six-month mission.

Crew Dragon hatch closure

10:10 a.m. EDT: All's well with the additional leak checks of Astronaut Josh Cassada's suit. Proceeding toward the next step, which is hatch closure. That's a delicate process and teams need to make sure there is absolutely no debris in the hatch's seals – even a human hair could trigger a warning.

Suit leak checks underway

10 a.m. EDT: Suit leak checks underway. A small variation in pressures was noted in Astronaut Josh Cassada's suit, so teams re-entered the capsule and adjusted the seals. Running through another check now.

What's left in the Crew-5 timeline

Here's what we expect looking forward:

• 10:05 a.m. EDT: Dragon hatch closure

• 11:18 a.m. EDT: Crew access arm is retracted

• 11:22 a.m. EDT: Launch escape system armed

• 11:25 a.m. EDT: Falcon 9 fueling start

• 11:58 a.m. EDT: Fueling complete, Falcon 9 on internal power

• 12:00:11 p.m. EDT: Final "go" for launch

• 12:00:57 p.m. EDT: Liftoff

Crew-5 checkouts underway

9:35 a.m. EDT: The four crew, now sitting in their custom-fitted seats in Crew Dragon, are running through communications checkouts at pad 39A. The hatch will soon be closed and its seals will be checked.

Crew prepping at pad 39A

9:30 a.m. EDT: Good morning from Kennedy Space Center, where SpaceX and NASA are on target for this morning's launch of the Crew-5 mission from pad 39A. Here's where we stand:

• Weather, rocket, and Crew Dragon capsule are "go"

• Crew departed Operations & Checkout Building just after 8:30 a.m. EDT and arrived at the pad shortly after.

• Getting secured in their Crew Dragon capsule.

• Up next are various checkouts like communications, scanning for leaks, adjusting their customs seats, etc.
