This is a boring party.

The guest of honor hasn't shown up yet. NET Sep

Who's that?

I suspect he means the LV.

But that is also not unique. Atlas V and Delta IV flew their first flights with relatively large payloads from paying customers, right?

Eutelsat got those launches for a couple of dimes on the dollar and already had plenty of bandwidth on orbit. It would not have affected business much to lose those birds. It was a high-risk bet (for this industry) that paid off.

SpaceX has multiple stages and dozens of engines flowing out of Hawthorne before the first actual flight of v1.1 and M1-D. This seems completely new to me -- parallel development.... Is this new? Is SpaceX confident or crazy? Or both?

This is how the US government ran the space & missile program in the 50s. Often when one would fail, the next few were expected to fail as well because they had the same design defect; but they were launched anyway to get more data. My vote is for both.

I imagine that CASSIOPE is getting a rather *substantial* discount on this launch.

Back in reply #143, ChrisWilson68 said, concerning turn-around time to the next flight of F9v1.1,

Quote

I suppose it just comes down to how long they need to analyze the data from the first flight to convince themselves there are no anomalies that need further investigation before they launch again. If all the data is clean, I don't see why that should take long -- really, they should have software already written to analyze the data and flag anything suspicious. If there's nothing suspicious, it shouldn't take long to clear it.

So, in theory, I think it's possible they could launch the next day.

In practice, with a new vehicle there are likely to be a few anomalies along the way, even if the flight is a success.

This makes a lot of sense to me.

It's a bit like baseball. Your team has loaded the bases but have two outs and your rookie batter is up. If he hits a grand-slam home run, the team scores a lot of points and the _next_ batter gets to come up to the plate and try to make a hit too. But if the batter strikes out or flies out, the inning is over and the next batter will need to wait for the next inning.

I'm hoping for a home run or at least an in-the-park triple.

I don't know what it is about the Octaweb (same number of rocket engines the 1.0 had) that now has me seeing this as a unique looking menorah with the slight axially offset "Shamash" engine in the middle.

Although I doubt anyone really wants to see a Falcon do a Proton impression since it would be upside down, flame side up, I guess I now have a couple months to come up with something before the holiday.

kevin-rf · « **Reply #187 on:** 09/03/2013 06:34 pm »

Proton doesn't have a center engine! That makes all the different

Maybe you can figure out how to make candles burn upside-down instead.

Sept 14th is creeping ever so closer. Can't wait for the hotfire...that's when the party gets started. Then, on to the launch!

Blow downward with a big fan.

kevin-rf · « **Reply #191 on:** 09/04/2013 09:27 am »

So if the candles get blown out, is it still a successful launch?

Does anyone know what that big flat, black piece is between the TE and the vehicle about where the interstage is?

I think it might be a net for the 2nd stage umbilicals. On F9-02 there was no net and the disconnected hoses impacted the T/E, presumably sparked and created a fireball from residual propellant in the lines.

You were right about the net

Well, I hope last Elon tweet is a good sign for the launch: sort of "let's open the party".
Now I'm waiting for the appetizer's BBQ.

spectre9 · « **Reply #194 on:** 09/04/2013 02:47 pm »

I'm just waiting around for the kick off.

Go Ravens!!

I know we're not supposed to discuss which sports teams we like here but I'm interested to know. Chris gets the occasional soccer reference in so I think it should be allowed.

Which NFL team do you'll follow?

I get into all things American. Not just the rockets. I'm not the typical Aussie yobbo.

You meant F9R (F-Niner)?

It's going to land in the ocean, right? Go SeaHawks!

Did this turn into a Handegg party thread?

I root for the Falcons on this thread too...except when they play the Seahawks...

I could say, "Go F9R's!!".
But never 49ers...
