Static fire!!

Looked good!
If the flight readiness review is good SN-09 should fly tomorrow or Friday.

Do you think that SpaceX will announce a countdown as they did for SN8?Originally Posted by docmordrid

For the flight? Yes.
Trying for another static fire o_O

Well best to get it right.

NSF reports it shook a hotel room at South Padre Island (6 miles)

And it looks like they are going for one more time?!!!

And yes three static fire tests in one day
Order of Kilopi
These static fire tests are short. I'm well aware that these are not full duration burns. Yet it is amazing how fast these rockets reach apparently stable thrust so they can finish the test.
Three static fire tests in one day, well well. Looks like they're having fun with their Raptors.
With sufficient thrust, water towers fly just fine.

They have faith in their creations, plus they needed to shake down GSE changes before flight (He pressurization of the headers, ground upgrades, etc.)
Order of Kilopi
Looked TOO short to me. Shorter than previous static fires, except the previous S/N nine one.

Awesome milestone! Back to back to back static fires!!!! We’ve never seen that before. Very impressive. And they still haven’t detanked.... think they’ll go for four?! 🤯

All three static fires completed & no RUDs!

Detanking & inspections now. Good progress towards our “Hop in & go to Mars!” goal.

Ok, Tim, but WHY do you need to do three static fires in one day? Or four? Maybe the first three didn't go exactly as desired?

Testing engine restart?
Order of Kilopi
Because they just made a change affecting how the system behaves when the engines start?
Established Member
Because they can?
It has, after all, taken months for SLS to do one static fire.
Order of Kilopi
This seems likely, either confirming a setup or multiple checks using different parameters.
With sufficient thrust, water towers fly just fine.

Yeah. Raptor is, after all, intended to be a highly reusable engine. And I think their record to date has clearly shown that SpaceX does not tend to drag their feet.

SpaceX's Starship SN9 prototype fires up rocket engines three times in one day. The three-engine SN9 vehicle performed its second, third and fourth "static fire" tests in quick succession today (Jan. 13) at SpaceX's South Texas facilities, near the Gulf Coast village of Boca Chica. The engines lit up briefly at 1:28 p.m. EST (1828 GMT), again at 3:22 p.m. EST (2022 GMT) and then yet again at 4:36 p.m. EST (2136 GMT). During static fires, engines blaze briefly while a vehicle remains tethered to the ground. SN9 already had one such test under its belt, having completed a short static fire on Jan. 6. These tests are part of the launch preparations for SN9, which will take to the skies in the coming days or weeks if all goes according to plan. SN9's flight is expected to be similar to the one performed last month by its predecessor, SN8, which soared about 7.8 miles (12.5 kilometers) into the South Texas skies.

SpaceX wins contracts for lunar lander, environmental satellite launches. Intuitive Machines announced that it selected SpaceX for the launch of its IM-2 lunar lander mission on a Falcon 9 rocket no earlier than 2022. IM-2 will land in the south polar region of the moon carrying payloads arranged through the agency’s Commercial Lunar Payload Services (CLPS) program in October. The IM-2 mission will fly a drilling experiment called Polar Resources Ice Mining Experiment 1 (PRIME-1), which will look for water ice below the lunar surface. Intuitive Machines said that, besides the PRIME-1 drill, two other NASA technology payloads will fly on the lander. Intuitive Machines also selected SpaceX for its first lander mission, IM-1. That spacecraft is scheduled to launch later this year as one of the first two CLPS lander missions. Both missions will use a lander design called Nova-C.

With all the static tests, you are going to have Ray's "Rocket Summer" out in the cold
Some help with landing legs?

"The chain composed of the origami cells showed … counterintuitive wave motion: Even though the compressive pushing force from the device started the whole reaction, that force never made it to the other end of the chain," University of Washington researchers said in the statement. "Instead, it was replaced by the tension force that started as the first unit cells returned to normal, and propagated faster and faster down the chain. So the unit cells at the end of the chain only felt the tension force pulling them back."

Sounds like they're targeting this weekend for SN-09's flight. No road closures yet, but they could come Friday (tomorrow).
FAA Temporary Flight Restrictions
Date: Saturday January 16
Window: ?? (assumed: 0900 - 1800)
Altitude: unlimited
Date: Sunday, January 17

Jan. 18: A SpaceX Falcon 9 rocket will launch approximately 60 satellites for SpaceX's Starlink broadband network, a mission designated Starlink 16. It will lift off from Kennedy Space Center in Florida, at 8:45 a.m. EST (1345 GMT).
Jan. 21: A SpaceX Falcon 9 rocket will launch the Transporter 1 rideshare mission with dozens of tiny satellites for commercial and government customers. It will lift off from Cape Canaveral Space Force Station in Florida, at 9:24 a.m. EST (1424 GMT).

If they've changed engines, shouldn't they do a static fire again?
The two different descriptions of the launch site made me chuckle!
