The @45thSpaceWing has released an updated weather forecast for the Starlink L3 mission, indicating launch is now targeted for NET Friday, January 24 at 10:54 AM EST (15:54 UTC). Forecast is 80% go.

Important to note that with upper level winds forecast at 110 kts the real probability is probably rather lower than 80%.

GO Quest has joined the fairing catchers and is now docked at the Port of Morehead City, waiting for launch day.

Tug Hawk and OCISLY are circling around offshore. The droneship is likely to stay at sea, but close to the coastline.

What are we seeing in that image of the landing?
Were the seas washing over the deck?

It's an LZ-4 landing in fog.

Waiting until after Atlas V's WDR to proceed with Starlink-3's launch ops.

During preparations for Solar Orbiter Wet Dress Rehearsal, a duct which provides cooling to the avionics, became detached from the Centaur upper stage. To be prudent, we will return the vehicle to the Vertical Integration Facility to conduct inspections.

So one less thing in the way of Falcon 9 launch ops for this Starlink flight.

Jeez. Anybody know if it's a day-for-day slip for Flight 4?

ZachS09 · « **Reply #51 on:** 01/23/2020 07:50 pm »

I knew all along that it's NOT going to be a fourteen-day gap between every Starlink launch. I said that in the party thread.

CorvusCorax · « **Reply #52 on:** 01/23/2020 08:02 pm »

Well, unless each delayed starlink launch pushes the next one right, too, they could still manage.

If the sat production rate, or availability of stages were the issues, they couldn't keep the rate. But if its only the weather, why should more than one single launch be affected?

Core refurbishment time? Fairing refurbishment time? Periods of bad weather like this are going to happen from time to time, not much they can do about it.

Yes, there will be sequential days of bad weather, congratulations on your insight, Captain Obvious.

This and the IFA test delays for landing zone conditions are reminders of the shuttle days when everything was ready to go except some variable in an abort location.

Rockets are hard, recovering them are harder.

This is why they will need to be ready to go in a cadence less than 14 days. Take the window when you can get it.

I noted in L2 that January 27 was the date of the Apollo 204 ("Apollo 1") fire. I can't remember a US launch, at least in recent years, that has taken place on this date, or on January 28 (the Challenger failure date). Columbia was lost on February 1. I was reminded that NASA's official "day of remembrance" is now January 30. Bad history, this time of year.

There's a chance it'll slip to the 28th. Not that they're gonna do it now or soon, but 60% violation of weather doesn't sound like they'll proceed with the attempt anyway.
