He'll likely talk about reusability and the new stage processing facilities at Port Canaveral. Once a stage ships to KSC it won't go back to McGregor, all work will be in the new facilities. They want to work down to a 2 week refurb.

 

McGregor->KSC->pad->launch->land->PortC->pad->launch->land....Etc.

Not that many as an assembly.  The landed stage with massive test-until-it-breaks burns is JCSAT-14.

 

This one: 1 proof test for each engine, a 3 minute stage fire at McGregor, a static fire, CRS-8 launch, reentry, landing, another long burn at McGregor, and this static fire.

Yeah, we should take bets on how long JCSAT-14 lasts ;)

 

That said, they'll probably stop at 10 since that was the planned design life for Block 3. 

 

If nothing else, that JCSAT-14 bird surviving a blistering hot reentry and all those long test fires shows just how tough a bird Falcon 9 is.

SES press briefing today. NSF's ChrisGebhardt reports,

 

Launch window was shortened to 1800 - 2030 EDT because FAA didn't want to close the airspace for 4 hours.

 

Tight timeline to make March 30; once F9 is vertical they need 13 hours for spacecraft checkouts. If they don't finish the launch slips to March 31.

Does anyone know if this going to be the case for all missions now? It's not really cooperative for commercial space flight. Something the FAA has been tasked with fostering from the beginning.

The Falcon 9 rocket has rolled out to launch pad 39A with the SES 10 satellite on-board, completing the trip to the pad surface just before midnight local time.

The next step will be to hoist the 229-foot-tall (70-meter) rocket vertical.

SES-10 MISSION

 

Quote

SpaceX’s Falcon 9 rocket will deliver SES-10, a commercial communications satellite for SES, to a Geostationary Transfer Orbit (GTO). SES is a world-leading satellite operator, providing reliable and secure satellite communications solutions across the globe.

 

SpaceX is targeting launch of SES-10 from historic Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. The two and a half hour launch window opens on Thursday, March 30, at 6:27 p.m. EDT, or 10:27 p.m. UTC. The satellite will deploy approximately 32 minutes after launch. A backup launch window opens on Saturday, April 1, at 6:27 p.m. EDT, or 10:27 p.m. UTC.

Just before the SES-10 rollout a peek inside LC-39A's hangar: three rockets at once, prepping for a run 'n gun series of launches.

Just a note,

 

This one will be a hot landing because of the payload mass & trajectory needs, so expect something like a 1-3-1 (engine) landing burn to conserve props. Definitely 50/50 for these hot shots.

IF it does land intact SES wants some part of it for their board room lobby, perhaps a grid fin or two, and there's another street corner on the other side of Hawthorne's main entrance. Displaying the first landed + the first re-flight sounds like a logical display set.

    • Microsoft confirms Windows 11 26H2 to finally get one of the most requested features

      If you don't care to read what I said, then you prove my point. Maybe written media is beyond your attention span. Titles are not summaries my friend.

      Nobody asked... in fact, I said "I don't care about political leanings"

      TLDR. Here is a far better title (just a basic example): Windows 11 26H2 to allow disabling Web search results

      There is nothing wrong with this title. You have completely missed the plot when it comes to "clickbait." The issue was never that a title tries to entice you to click, that is how titles have worked for over 100 years. The issue is when the title subverts expectations, getting you to click expecting something that isn't there. The classic clickbait example is "Boyfriend caught cheating, what happens next will shock you," then what happened next is the girlfriend was upset...which is probably the least shocking outcome imaginable. If sounds like what you want is for the titles to be a collection of 10-word summaries that you can skim, get the just of the story, and only click if you want more details. That is not, never has been, and never will be what titles are. You can go all the way back to print newspapers during the great depression and see the same thing. The newspaper was locked in a vending machine, all you can see is the headline, you choose to put in 5¢ to buy the paper and read the rest if you want. Those headlines were written in a way to sell the paper, not just to provide a summery. Here are two actual headlines from that time, "Wall Street Lays an Egg," or "Stocks Hit Bottom?" Maybe you'd say something like "it was wrong then and it's still wrong now." Okay, fine opinion to have, but it isn't like Neowin is doing something unjurnalistic, they are just following the age-old standards for written media.
