SpaceX Sets Feb. 24th Target Date For Next Launch 42
Rei writes: After some consternation about the pacing of Falcon 9 upgrades, SpaceX has announced that it plans to launch again from Cape Canaveral with a target date of February 24th. While the primary mission will be to place the SES-9 communications satellite in orbit, this will also mark their fourth attempt to land the first stage on an autonomous drone ship, after their last launch touched down softly but fell over when one leg failed to latch. SpaceX is working to significantly accelerate the rate of production and launches — they are reportedly moving the factory from 6-8 cores produced per year to 18 at present, and expect to reach 30 by the end of the year. After the upcoming launch, they expect to launch one rocket every two to three weeks.

Not seeing the connection. Somebody's going to be launching satellites either way, whether it's SpaceX or a competitor.
Also, don't confuse cores with launches. The Falcon Heavy is three cores. Of course, offsetting that, there's the potential for reuse of rockets...

Not that I am at all opposed to more satellite launches, but... how can you possibly believe that SpaceX increasing the global supply of (relatively) cheap rocket launches won't affect the quantity of stuff launched into orbit?
This is like, economics 101 - when supply goes up and prices go down, demand increases in response.

I wouldn't expect a huge shift in the size of the global launch market at current Falcon 9 pricing. Now, with reusable Falcon 9s, or multiple payloads from Falcon Heavies at current quoted launch prices, that could be a different story...

Arianespace and United Launch Alliance have both basically announced that they're replacing their current launch vehicles specifically to be more competitive with SpaceX (although perhaps not in so many words). Clearly, SpaceX is having a real impact.
It may not be a world-changing impact, but all the OP said was, "more space junk!" Even the Kessler syndrome allusion is not that unreasonable, considering that some people think we may have already crossed the point of no return.

Of course they're taking business from other players - but that's not the question. The question is if they're making new business that otherwise wouldn't be there. Thusfar, I haven't seen anything to suggest that.
But, the potential is there in the future if they can keep bringing down costs, as they're hoping.
And IMHO, we're not even remotely near the point where space junk is going to stop us from launching things into space. Not even close. Particularly in LEO where orbits decay relatively quickly.

Again, economics 101 - they have already brought costs down across the industry, and the burden is on you to prove that demand for satellite launch services is completely inelastic in this price range. Otherwise, the OP's claim of "more space junk" cannot be reasonably rejected.

No, they're making the claim that there will be an increase in the launch rate, an increase that we haven't seen. The burden falls on them to prove that one is suddenly going to materialize. It's their claim. My counter is simply: "where is it?" Where is this supposed surge?

One of the things SpaceX and others are emphasizing for "the future" is small, expendable cubesats in LEO, e.g. for SpaceX's Internet plan. This is low enough that atmospheric drag brings things down relatively quickly. If launch costs are low enough, and SpaceX's satellite factory and general commoditization of satellite components keeps progressing, this could be beneficial as far as the space debris problem is concerned.

Perhaps, but it also increases the cheapness/opportunities of sending up debris cleaning satellites as well. The space faring nations of the planet should develop/build several classes (cubesat, small, medium, large) of debris cleanup satellites. Form cooperative agreements with the launch companies to the effect that whenever a space launch has some capacity that would otherwise go wasted fill out that spare capacity with the appropriate debris cleanup satellites as a secondary payload.

The booster isn't strong enough. Much of it is about as thick, and as strong, as a coke can (but much bigger). There are just enough structural ribs and the like to support the load during launch (and after landing) but if you grab it in the wrong place it will just break. The mass is mostly at the bottom (engines) so I gather it's quite stable once it's sitting on its feet and they weld covers over the feet to hold it in place for the voyage home.

Why not use some sort of collar made of cables on some masts around the deck to support the top of the booster? When the booster come in, the hoop is wide open so as not to obstruct. As it passes though, the loop tightens and the booster is kept upright even if it tips. By the time it lands, the loops is snug against the top of the rocket and the booster is secure, even if the platform rocks.
That was actually my first reaction: "Oh, obviously it'll be something like 'this' that they'll be using...", the first time I heard they'd be landing them at all.
Then I got really annoyed at them not having something like that, and trying to land on a pitching platform.
The platform landings themselves make sense, particularly if you locate the launch and landing facilities out in international waters so that the world really has no say in whether or not you are allowed to launch and/or land, but really: th

However, if I am designing an experiment, I try to limit any simultaneous changes to dependent variables.
That's not to say that I *won't* (I have) vary multiple independent variables at the same time, but if I do, I usually have at least a "hunch" that the direction I'm moving them both (all) is toward a saddle point.
Perhaps the person deciding this has already concluded the independence of the variables and the probable location of the saddle point. If so, good on them; from outside, I really haven't

- 100% of the Falcon 9 Full Thrust landings have been successful.
- 0% of the Falcon 9 v1.1 landings have been successful.
- There has been one F9 FT flight so far.
- The F9 FT has (among others) improved thrust (and thus more reserves for the return flight) and improved landing gear.
- After the successful return of the F9 FT some things were noted about the FT drives and launches were pushed back 4-6 weeks as it looks right now.

Or the ground landing was a "Oops! We accidentally landed successfully! Let's blame the equipment! Back to the barge! Arrrrrr, maties!".
Multiple successful ground landings would have been good. But they aren't planning to refly the thing even if it's a successful landing at this point. But that does move us 3 launches to reuse from first landing to probably 6 launches to reuse. If they have money to burn on it because they are rolling it into launch costs, it makes sense to roll as much of it as you

The point of the second article was that SpaceX wants to Dramatically Accelerate Its Launch Frequency [fool.com] and, if all goes as planned, the company will achieve a launch rate of once every two to three weeks. They have 40 Falcon 9 missions and 6 Falcon Heavy missions on their manifest. The more launches, the more chances for problems but for now the only constraining factor appears to be the number of cores they can produce. They need 61 cores for their current manifest (40 x1 F + 7 x3 FH) so even if they inc
