SpaceX flight testing in South Texas

[kit344]

This is intended to be a new thread about the Boca Chica testing and development site in South Texas

I have started this separate SpaceX thread because this activity is a separate program from Falcon 9, and today also marks the 5th anniversary of the first successful Falcon 9 landing.

Starship SN9 rollout is expected in the next few days, today's rollout was the giant "Tankzilla" mobile crane.

When do they expect to launch SN9?

[TURIN]

Probably mid January, depends how much static testing they do. Don't forget SN9 had a mishap so until they cryo proof check it we will know nothing.

Salute!

You can see live TV of various locations at the Boca site, and there's a "discord.com" site that LabPadre will reference. The discusion forum is more like a chat than PPRuNe.

The You tube ref had good coverage of latest hop and covered movement of next Starship to the launch pad.

Not sure if the link wil get you to the LabPadre discussions but try it:

They are finally clearing the landing pad ready for SN9 flight.
Speculation in various spaceflight forums and Facebook groups that the flight could be as early as this week.

NOTAM for Friday 8th January

Anyone know where they're planning to land their first orbital flight(s)? The re-entry path for a Texas landing would be straight across Mexico, which doesn't seem the greatest idea for the first orbital re-entry of such a large/radical vehicle.

Not all orbits are W-E. The path varies with the orbital inclination, and would probably be North of NW for an approach to Boca Chica TX.

Lots of discussion about things like this in the forums at nasaspaceflight.com

The idea is to land the booster right on the launch pad, ready for a quick (1 hr according to Musk) turnround.
Similarly, the Starship itself needs to land close to the booster to allow a similar refuel and RTS. .

That all makes sense (and, if the booster's launching over water its return path will be over water).

What I'm getting at is that there appears to be no orbit for which both launch and re-entry trajectories are over water. Launching over water from Texas and then returning from orbit to the same location seems to commit you to a re-entry path over land; that might not be an issue for a proven vehicle, but seems a bit of a risk for the first few orbital flights of a vehicle very different to any that's flown before. Look at what happened to Columbia; that didn't hurt anyone in the ground, but it could have done.

[TURIN]

Some of the musings ive read seem to indicate that the Starship re-entry profile will be substantially different to 'normal' parabolic reentry. I'm not an astrophysist or rocket scientist so ive no idea what that means. Stop dead and drop straight down perhaps?

Anyway, a successful static fire of SN9 took place today and SN10 has received its nose cone. All moving along swiftly. Another launch Saturday maybe?

NOTAMs updated.

Possible dates now not earlier than Sunday 10th, with Monday and Tuesday as alternates.

It looks like the Static Firing on Wednesday 6th was not "Norminal"
It was a very short event, and it looked to me as if only 2 out of 3 Raptors actually ignited.

There will be another Static Firing, no earlier than, NET, Monday 11th
Earliest possible flight date is now 12th January, with backups on 13th and 14th.
There were a couple of road closures for Static Firing in the last couple of days, but no engines were lit.
NOTAMs are here https://tfr.faa.gov/tfr2/list.jsp with an option to filter Texas or Space Operations, but I couldn't see any way to use multiple filters.

[kit344]

Static fire is still possible up to 0200 UTC on 13th, 20:00 CST 12th.
No firing was done yesterday, due to either SAR helicopter operations, power outage, or very strong winds.
TFRs have been added for one additional day.
Air Force One was also in South Texas earlier, so NOTAMs for that as well.
