They've said 10-20, and I think they actually regard the real number as possibly much higher from things I have read.

Sure, but I think we've already established that SpaceX SHOULD be charging whatever the market will bear for every (paid) launch, so there ought to be a tidy profit margin off those first 20-odd a year. If they run off another 10-20 upperstages at the same time they do the first 30, and produce more Dragons for in-house use, Elon can run his private space program for effectively peanuts.

I guess it depends whether it would be cheaper to use a Falcon Heavy in reusable configuration to lift 20 ton payloads. Which, in turn, depends on how reusable Falcon Heavy actually is and how much of a saving reusability actually gives them.

My gut feeling is that Falcon (expendable) would probably be cheaper than Falcon Heavy (reusable) for a 20-23 payload but then my gut knows exactly diddly-squat about rocket science. :)

*doffs Captain Obvious hat*

Also depend on how long they will reuse one stage, it might well be cheaper to use an old first stage who would need serious maintenance for more use rather than an FH.

"fully expendable configuration," 

That reminds me I've been meaning to ask. Will the Falcon 9 ever fly fully expendable again?

Will likely be required for some NASA or DoD high-energy mission.

According to SpaceXStats it's on the 27th...

https://spacexstats.com/missions/thaicom-8

 

spacexstats converts times and dates into your local time zone.  Since there's no time, just a date, it's probably assumed the launch will happen at 12:00 am on that day, UTC.  For me, it comes up with the 26th.  After mousing over the date, I selected UTC, and it showed the 27th.

Yea my time zone is CET, so it's 27th for me :)

Is there any more information on the 2018 mars mission? The only info I found was from 2 weeks ago when the tweet actually came out.

Well, that article surmises (not reports) that the booster "may" not be in shape to fly again. That's not really confirming anything at all.

The relevant thread on r/SpaceX has over three hundred posts in it, and so it's difficult to get a good overview, but so far I've not seen any confirmation there either. Even EchoLogic, who's very obviously in cahoots with various insiders in the company, is just speculating.

I do like the top comment by u/BridgesOfKoniksberg in there though, so I recommend everyone to check it out here. Gives some background on what the heck a "life leader" actually is.

Another question. For small payloads, eg cubesats, wouldn't it be cheaper to have them as primary payloads on an upgraded falcon 1 (merlin 1d+ engine instead of merlin 1c for example), instead of having them as secondary payloads in the falcon 9? I imagine it would also be better for the satellite producers since they would not have to wait until the big primary payload is finished to launch on a falcon 9 months or even years away, instead they could expect a sooner launch of just a month or 2 of waiting time. 

Any thoughts?

There are dozens of "new space" operators lining up to cater for the small sat launch business. There hasn't been much of a market for it, which is why SpaceX abandoned the Falcon 1 in the first place.

Cubesat operators typically don't have money, so are they are not really a viable market. They would rather to wait for a free/cheap ride with another payload than pay for their own rocket. There is no indication that a Falcon 1 would be cheaper than a piggyback ride.

There are economies of scale with rockets. Larger launchers generally post significantly better $-per-kg-to-orbit figures.

Examples:
- Vector Space Systems plans to offer 25kg to sun-synchronous orbit (SSO) for $2 million with their yet unnamed, dedicated "microsat launcher".
- Rocket Lab is offering their Electron rocket for $5 million, and it's rated to loft 150kg to SSO. Now, there are many different SSO's, and Vector Space Systems didn't really specify which one they meant, but based on the payload-to-LEO drop of their vehicle comparted to that of the Electron, it's highly likely that both companies are advertising the same 574 km low-altitude SSO here.
- The Falcon 9 is advertised with 'up to 5.5 metric tons to GTO' (not current capabilities, but the capability you get when you buy a launch today) for $62 million, rocket only. The launch campaign itself costs another 40% to 50% on top of that, so let's say $90 million total.

In this case, you pay:
- $80,000 per kg to low SSO with Vector's tiny rocket
- $33,333 per kg to low SSO with the somewhat larger Electron
- $16,363 per kg to GTO with the much larger Falcon 9 - and geostationary transfer is a much more demanding destination than the low altitude SSO the other two companies advertise. To that same orbit, I would speculate that the F9 would be down to four digits. So even 'classical' large launchers that aren't as aggressively cheap as the F9 will still beat the Electron in price every time.

This also assumes that the two smaller companies are quoting the entire launch (vehicle + campaign), and not just the vehicle. If they quoted vehicle only, the balance would shift even more towards larger rockets.

The only reason the smallsat launch providers still think they can make money is because ridesharing on large rockets is inherently problematic - you may have to wait for years to find a rocket that goes where you want to go. Some small satellite customers have said they are willing to pay a bit extra for dedicated launches that go when they want, where they want.

Rocket Lab "has already secured commitments for at least the first 30 launches" of the Electron, according to this article. Even if that's just expressions of interest and not sales, that's fairly impressive for a rocket that has never flown, targeting a market that doesn't exist... :wink:

(As far as sales go, last I read there are a minimum of seven paid flights on the manifest, but unfortunately I don't remember where I read it, sorry. It was months ago.)

They may plan on the FH core to carry a larger reserve propellant budget so it can brake heavily in boostback.
