I think the biggest compliment paid to Elon is that nobody immediately called him an idiot for saying they wanted to catch it, they instead just said they were excited to see how he'd pull it off.
I thought he was joking with the guy on twitter when he first said it.

Then I was like "I bet they could pull it off"

Then I watched this Scott Manley video and I'm like "yeah, this is what they should do to protect the engines..."

The grid fins make sense because apparently (and no surprisingly) they will have a higher stress on them during re-entry than just "hanging" the empty booster on them.

Nothing happened yesterday and the road closure was cancelled for today buuuuttt - it might fly over the weekend!?!?

With Starship SN8's test flight still fresh in the memory, SN9 is set to complete an accelerated pad flow with a Static Fire test and launch this coming week. A triple Raptor Static Fire test is tracking Wednesday. Pending acceptable test results, the launch of SN9 could take place just a few days later, on Friday.

Meanwhile, Starship SN10 is now an integrated stack inside the High Bay, ready to roll to the launch site as soon as SN9 departs. SN11 and SN12 are undergoing their own buildup operations inside the Mid Bay, with the former only lacking a nosecone.

Great thread FWIW.

I enjoy all the participants' contributions from someone sitting here in the gallery.

Who knows. They're very good at being both transparent and not transparent at the same time.

I actually think they're being a bit more cryptic with starship to try and keep the crowds down TBH. With the thing being as incredibly experimental and potentially hazardous to bystanders as it is, I wouldn't really want a crowd standing around 9n the road either lol.

Pad is cleared now for the static fire today.

EDIT: looks like a good static fire today although it was a little shorter than some I've seen

A lot of speculation/oddities around the static fires (2) yesterday. Maybe deliberate, maybe not, hand delivered notices to folks nearby, not clear if they will do another static fire today or not. Also, Falcon 9 launch number 1 of 2021 is for today (60 percent chance).

https://www.teslarati.com/spacex-starship-sn9-triple-raptor-static-fire/

It could, if the static fires work/worked, still fly Fri-Sat-Sunday, but it sounds iffy.

Quote:

Relatively late into a test window that opened at 8 am CST (UTC-6) but was later pushed to noon, SpaceX's first Starship SN9 static fire attempt began in earnest around 3:15 pm CST. Signified by venting activity at the propellant farm tasked with preparing and loading liquid oxygen and methane on Starships, slight tweaks in the test flow were observed but the static fire occurred more or less when expected at 4:07 pm.

SN9 ignited all three of its Raptors in quick succession and shut the engines down over the course of 1.5-2 seconds extremely short relative to all previous nominal Starhopper or Starship-mounted Raptor static fires. Long-time followers immediately noted that small discrepancy, speculating that it could either have been a post-ignition abort or intentionally shortened to avoid damaging the pad's concrete surface (an incident that's occurred several times during recent tests).

It's unclear what the actual goal of the second attempt was and it's more or less impossible to know for sure with(out) confirmation from CEO Elon Musk. It's possible if unlikely that the first static fire went exactly as planned and the follow-up test was meant to be a simple data-gathering wet dress rehearsal (WDR). Either way, after a surprise downpour briefly engulfed Starship SN9 minutes prior, the second test appeared to abort about 30 minutes into propellant conditioning and loading, precluding both a complete WDR and/or static fire.

On January 5th, SpaceX received a trio of Temporary Flight Restrictions (TFRs) from the FAA that will allow the company to restrict access to nearby airspace for high-altitude Starship launch attempts on January 8th, 9th, and 10th. Lacking an unequivocally successful static fire, it's highly unlikely but not impossible that Starship will be ready for a launch attempt during any of those three windows. Still, it's safe to say that SN9 is probably less than a week away from its first flight expected to be a carbon copy of SN8's 12.5 km (7.8 mi) launch and landing attempt if SpaceX can complete a full-duration static fire in the next day or two.
I'm reminded of some of the pressure (from a comment at the link) as to the starship (and super heavy booster) timeline; the Mars 2022 window opens in a mere 600 days. It only opens every two years (roughly).

Sorry if I've missed it, but has Elon or SpaceX talked at all about actual development activities toward an initial system that might be sent in any particular Mars launch window, never mind one opening in 600 days? Seems odd that it isn't plastered everywhere if Elon really believed it was happening.

Yep, they're doing a good job at it. I wish Sierra Nevada would take a page out of his book, tell ULA to get ****ed, and start advertising better.... They're going to find that getting out of Boeing's grip will help them.


Musk has talked a lot about wanting to launch for the '22 window with a starship, but their plans change day to day. I think he would LIKE to send some form of unmanned starship out during the '22 window, but I don't see it realistically happening.

I think this was...his most recent comment on the timeline(s) for mars missions/windows;

Quote:

I think...I feel fairly confident about six years from now. So every...the Mars...Earth-Mars synchronization occurs roughly every 26 months. So we had one this year, this summer and that means in roughly like about two years will be another one, and then two years after that. So I think, I'd say if you say six years from now I'd think highly confident, if we get lucky maybe four years. And then we want to try to send an uncrewed vehicle there in two years.
The unscrewed vehicle would probably be a basic starship without any life support systems onboard at all (possibly just to orbit and return). Even the latter would require it to be refueled (by another starship) in orbit around the earth first, which would be a pretty big deal/milestone.

Now, the below video (angry astronaut guy) is a little obnoxious but he does an interesting job here theorizing how Buzz Aldrin's Mars Cycler type of vehicle/trajectory could, again just theoretically, use/cooperate with SpaceX. Buzz put a neat 10 minute movie out about his 80's idea recently if you want to see more of it, and here is his organization (he's a huge advocate for humanity to explore/colonize space).

How is Sierra Nevada in Boeing's grip? What does Sierra Nevada gain by telling off ULA?

SNC chose the ULA Vulcan for the dream chaser launch vehicle, and also their (Dynetics) moon lander design/program. Frankly, even Blue Origin might have made better sense as a paper 'partner.'

I assume that's what he's referencing.

I'm aware of that. Boeing doesn't operate ULA. They have an ownership stake and ULA operates independently. I'd like to see Ag_of_08 clarify how that puts SN "under Boeing's thumb" and how their selection of ULA as a launch services provider has caused them an iota of hardship.

SN9 won't launch until Sunday at the earliest. Right now it's Sunday, Monday or Tuesday.

Sierra Nevada's ability to launch is tied to their competitors at this point. You actually think Boeing and ULA wouldn't intentionally try to slow them down in launch cadence if they suddenly became publicly critical of them? That's living in a fantasy world.

Just like Orion will now no longer launch on a different company's rockets since the AJ/RD merger.... all about the money, and who controls what interests and assets. ULA, and Boeing specifically, is not going to allow themselves to be passed by a competitor on their own rockets. Even with ULA's alleged independence, Boeing and Lockheed are the big dogs in that company..

It hasn't caused them grief yet. My point was them becoming more open in competition with Boeing.

ULA is really just LM and Boeing, the 'last men standing' of the old US launch industry (which by default largely favors things being done as they have been). It's essentially just an accepted truth among the 'disruption is needed' crowd (for lack of a better word/phrase) that anything relying on/paying them is bad for the disruptors (SNC/Spacex/Blue Origin etc).

It's not real complicated to understand the perspective, even if it's simplistic, imho.

AA has been a big fan of SNC and of course loathes ULA/Blue Origin so his take on it is sort of in line with the premise.



I'm a bit sympathetic to SNC as I think they just don't have a lot of great options as to who to partner with for lift (considering who they are basically competing with).

I think Musk would have ended up a better partner than ULA at this point. Yes he's still the competition, but they're not going to out compete the dragon, much less starship.

I saw that video pop up in my recommendation, but haven't watched it yet.

So you're just speculating that ULA would engage in illegal anti-competitive behavior to favor one of their partial owners despite all available observation that ULA operates as an independent and agnostic launch services provider.

The irony here is that ULA is the only launch services provider that doesn't have competing operations with SNC. SpaceX competes with SNC for cargo delivery. Northrop competes for cargo delivery. You suggest SNC get out from "under Boeing's thumb" and run to a firm with... more conflicts of interest.

The further irony is that ULA launched cargo resupply Cygnus vehicles for Orbital ATK (now Northrop) who *was* a direct competitor for launch services. There were no allegations of evidence of funny business there.

We get that you don't like Boeing. But unless you've got some actual news or facts to share, I suggest you not derail the thread about news or facts about SpaceX.

But ULA and it's constituent owners have been caught engaging in lies about competitors, borderline anti-competitive practices, and lying to NASA.

And I'm not talking about SNC as a commercial cargo provider, im talking about them as a better option for commercial crew. Punting starliner, then funding dreamchasers completion as a man rated vehicle( which is not a pipe dream.... its what it was designed for) is going to end up being a safer and more responsible route.

That will not happen with it flying on an ULA rocket, just like Lockheed won't allow the Orion to be launched on an alternative system now that they own AJ/RD. You can feign outrage as you like, but yes, I am implying that, faced with cancelation of billions in contracts, Boeing would act in an anticompetitive manner through ULA.

I'm afraid it will all be a more or less moot point for the next 3-4 years anyway, maybe longer. The traditionally anti-space faction that is back in power now will likely cancel artemis, but have no backup ready for it. Hopefully the independents will keep the momentum up, but I'm not sure at this point. I'm glad the military has begun diversifying the launch providers it uses.



On a much lighter note- has anyone heard any more out of ISRO and their capsule? They flew the boilerplate, and then things got very quiet.

All good points.

The Indian budget is under $2 billion a year, so I expect, as with defense contracts in India, long periods of radio silence after anything happens.

Happy note, Viasat lost another effort to stymie Starlink. Polar orbits approved.

Bad news, static fire tomorrow, so no launch today. No earlier than January 12th as of right now.

Not trying to hide the lede here, the real news of this video is that the BE4 (Blue origin) engines appear to have been installed on a Vulcan Centaur (for 2021 launch).



Oh, and we still have no idea what the heck happened with that extra-terrestrial object (Oumuamua). No big deal.

The accents of the two on this video are a bit abrasive, but I like their takes/analysis.
