It's pretty well documented that people at SpaceX work 80+ hours a week consistently: https://www.quora.com/How-many-hours-a-week-does-a-typical-S... http://spacenews.com/op-ed-3-things-to-know-if-you-want-to-w... https://www.reddit.com/r/spacex/comments/25ixxq/is_spacex_wo...

Thank you. So they are paid overtime for this, is that correct?

The hourly employees, sure.

You can't vent rocket fuel, the kerosine will ignite from the expansion and the friction in the valve alone. Venting liquid oxygen is also a really really bad idea.

On the contrary, venting LOX is very common and easily visible in the lead-up to nearly every Falcon 9 launch. Google "falcon 9 lox vent" for plenty of videos/photos.

The "venting" you usually see isn't LOX, it's condensed water vapor, there are small bleeder valves in the LOX tanks and the fuel line but they are not designed or used for emergency pressure relief.

I suspect the $2b custom government bird refers to the space shuttle. Of which we have, in fact, lost more than one.

That figure's low by a factor of 100 for the Space Shuttle program.

Specifically referring to the cost of the orbiter vehicle itself (or the cost you'd incur building a replacement if you lost one), roughly $2 billion is a decently accurate figure. The shuttle program as a whole, yes, is drastically more expensive.

"The Space Shuttle Endeavour, the orbiter built to replace the Space Shuttle Challenger, cost approximately $1.7 billion." http://www.nasa.gov/centers/kennedy/about/information/shuttl...

The Israeli government has approved the deal with China, if they didn't want it to go through they would have blocked it, their MOD has oversight on virtually all exports and international dealings. Israel needed AMOS-6 more than anyone else because communication satellites are important for national security and are used by military and national defense agencies. Even if somehow your crackpot theory had merit delayi…

> Even if somehow your crackpot theory had merit We try to avoid that kind of tone here, regardless of the merits of anyone's comments.

Fact is, the original was very racist.

Just cleverly(obviously?) hidden.

Why would a country blow up it's own stuff when it's obvious there are better ways. (Undertone they are culturally/genetically stupid)

I find this worse, I thought the reply was kinda tempered.

Sounds like SpaceX just killed multiple deals for this company. Could someone who knows about this kind of stuff (I assume this subset of the population is small) comment on whether there is recourse against SpaceX for losing the payload?

The risk of this happening was almost certainly accounted for in the contractual relationship.

Quite possibly with a termination clause. Insurance typically covers the cost of the satellite, not the cost of delaying time to revenue by what could end up being several months or years.

It takes years to build a satellite, the bus, and every component is purposely built each component and the satellite itself goes through months of testing and even if they could build one within 6 months all of the contracts would expire by then which will require Spacecom to open the bids again. All of the contracts were based on AMOS-6 being operational by a given date, AMOS-6 has been "under construction" for pro…

That's why you always build two.

This was my first thought but then again I don't know how expensive the one was and if they built one and it launched successfully, what would they do with the second one? Seems like a damned-if-you-do-and-damned-if-you-don't scenarios.

That was my immediate thought too. Israel is known for playing rough when it comes to sovereignty concerns, particularly of a technological nature.

Let me point out in a nicer way what dogma1138 said below: Why would they want to do it in such a way when they could have stopped it just with formalities. I know Israel isn't right all the time but there is little reason to believe they are stupid.

Same reason they did a false flag bombing attempt on US and British targets in the 50s instead of simply asking for support?
