Earlier quoted context omitted.

Is "the ocean was wavy" really a justifiable reason for losing the rocket? Surely sea conditions are something they'd take into account when planning and executing the mission.

Is "recover an un-manned rocket" really a justifiable reason for potentially losing lives at sea?

Not really. Which may explain why (according to one report) the Coast Guard refused to go out after the booster.

Is it SpaceX's intention at some point to forgo the launch tower and launch directly off of the landing legs grasshopper style? I realize it's not really necessary, but it might make it easier to get a rocket off of Mars instead of having to build a tower. Although, presumably if you can refine rocket fuel on Mars, maybe building a launch tower is no big deal. Anyways, kudos again to Musk and SpaceX.

The strongback does a lot more than legs ever would: resistance to winds when awaiting the launch window, fueling, data connections, etc. Not to mention you need some sort of tower to lift the rocket upright after payload integration and servicing -- unless you do vertical integration, which they will need to do to win USAF contracts. But then you need a crane, anyway.

Equally large news from today's press conference at the National Press Club - SpaceX is taking on ULA (united launch alliance, a consortium of incumbent players in the market) and the "block buy" allocation of military / national-security launches to ULA. Here's their handout, from one of the reporters there: https://twitter.com/jeff_foust/status/459734785314013184 Playing politics a bit, Elon's claiming a ~ 75% redu…

Musk said a normal Falcon 9 launch is $60 million. I'm not sure exactly what's involved with "Government-driven costs in addition to the cost of launch services" but I'd hazard a guess that they're not $40 million per launch. Could end up being a nicely profitable sale for SpaceX if they can pull it off.

Musk estimates that Air Force "mission assurance" requirements would cost $30 million, hence a $90 million ("under $100 million") price-tag.

"Seems like the wrong time to be sending hundreds of millions of dollars to the Kremlin" -- Elon Musk He's certainly not making friends in Russia today. That said, I feel like the ISS is too important to be left to the whims of the US Congress. IIRC NASA plans to deorbit the American part of it within the next decade, while Russia keeps the rest aloft and turns it into a waystation for planetary missions.

What is your source on that? According to a page on the NASA site from Oct 13. The Station is expected be operational through at least 2028.

- Successful soft landing in the Atlantic - Seas were too rough for a quick recovery - Rocket subsequently destroyed by wave action - Will attempt recovery of the next Falcon 9 launch - A Falcon 9 recovered on land could be re-used the next day (!) - SpaceX is lobbying to allow private competition for National Security launches (eg GPS satellites)

Is "the ocean was wavy" really a justifiable reason for losing the rocket? Surely sea conditions are something they'd take into account when planning and executing the mission.

The launch window was being dictated by factors other than the landing weather and storms in the Atlantic are a justifiable reason for losing pretty much anything you care to put in them.

My jaw dropped reading that the rocket could be re-used the next day. That seems like an enormous leap forward for space flight.

Well, F* nationalists. Earth is too important to be left to the whims of crazies like you.

While I agree that it is definitely best to use domestic launchers and not have to rely on the Russians for engines or astronaut launch, I don't think that "Fuck the Russians" is really a great expression of that. Since Apollo-Soyuz, spaceflight has been something that our two countries can productively collaborate on, despite our (at times, vast) political differences. Maintaining good relations between NASA and the…
