The EELV program doesn't actually require two different providers to guarantee access to space. It requires two different families of launch vehicles. ULA had the Atlas V and Delta IV families.

... and Delta IV Medium is being retired, because it's expensive and no longer needed as the second medium launch vehicle.

Also, they want Vulcan to replace both Delta and Arian family. Thanks to SpaceX they don't need two anymore.

I'm familiar with this article. First, "adventure" is a reason to go there, not to settle. Second, I'm not buying the "drastically improve humanity's chance at survival" argument. There have been several mass extinction events in the past, so in order to survive one that might be coming, we should move to a place where there is likely no life at all? That does not make any sense to me. If we can survive on mars, we c…

> If we can survive on mars, we can survive on Earth no matter what can plausibly happen to it. Exactly. So going to Mars and staying there long-term will require us to develop many solutions that can be applied here on Earth. Both under current conditions and conditions that would currently be civilisation-threatening.

So the whole thing is nothing but an exercice in survivalism? That is ludicruous. There is no need for that.

Next time, just spend 15 minutes to automate it. :)

Then 2 hours maintaining and improving it.

1) Add this as a bookmarklet called "Inject jQuery". Then click "Inject jQuery"

     javascript:void((function(doc)%7Bif(typeof jQuery%3D%3D%27undefined%27)%7Bvar script_jQuery%3Ddocument.createElement(%27script%27)%3Bscript_jQuery.setAttribute(%27src%27,%27//code.jquery.com/jquery-latest.min.js%27)%3Bdocument.body.appendChild(script_jQuery)%3Bconsole.log(%27jQuery included %5E_%5E%27)%3B%7Delse%7Bconsole.log(%27jQuery already included ...%27)%3B%7D%7D)(document))%3B

2) Type this in console:

    copy(jQuery("a").filter(function(idx,el) {  return jQuery(el).attr('href').indexOf('vote')!==-1; }).map(function(idx,el) { return 'https://news.ycombinator.com/' + jQuery(el).attr('href'); }).toArray())
3) Install this Chrome extension and paste the contents of your clipboard

Just need a pissing contest between SpaceX and Blue Origin now and everyone will benefit

Blue origin isn't even in the same league. Their rockets go straight up, stay there for a bit and down again. Spacex achieves magnitudes higher velocity, altitude and actually delivers things to orbit. BlueOrigin is Bezos' pet project akin to taking a heli tour around the city while SpaceX is doing a transcontinental flight half way around the world.

That's true.

It's also true that BO are not standing still and their plans look good overall. I think it's inevitable that the industry will explode with competition at some point not too far from now.

It's a bit disappointing to me that poverty, human trafficking, addiction, habitat destruxtion, cultural erasure, genocide, torture, extinction, etc aren't very powerful motivators for such people. I feel such pressure to use our new skills to solve these problems, but I know 10 years ago they were a combination of invisible/impossible to me. If I hadn't been aggressively pushed by smart feminists to examine my life…

The thing about Mars is that it does not solve any problem. It just give us time to solve the problem. It mulitply the chance of humanity surviving a problem that kills our only "capsule", Earth. And that dangerous event could be external to humanity. So Mars is a part of a solution for all that : buy all the rest of humanity time to solve that problem and making sure enough humans can be born and live so that at lea…

There are no plausible scenarios where survival of the species is easier on Earth than on Mars. Even in the worst runaway climate change scenarios or the worst nuclear war scenarios, Earth is still more habitable than Mars.

Russians no chance the degree of corruption makes any serious project a guaranteed failure

You're underestimating Russia ridiculously.

Would you care to provide an example to the contrary? Look at Rosnano, Scolocovo or any other multi-billion dollar project with 0 ROI.

That's not really a fair comparison. The amount of money you lose if something bad happens is more than just the cost of replacing your payload (which is what insurance covers)

Why wouldn't they obtain insurance for the total cost of the mishap?

Losing a payload can have a domino effect of bad things that insurance doesn't cover. Kind of like how your car insurance won't pay for your lost income if you get in an accident and then get fired for missing work. Maybe the car analogy is a bit of a stretch, but look at Spacecom, whose Amos-6 satellite blew up during a static fire back in September (this wasn't actually covered by launch insurance, but Spacecom had separate insurance for anything that happens before the launch).

Beyond the cost of a new satellite (covered by insurance) and a new launch (SpaceX is giving them one for free) Spacecom still has to provide coverage for their customers. The solution is to lease someone else's satellite for 4 years, which cost them $88 million [1]. On top of that, they were in the middle of selling the company for $285 million. The deal was contingent on the Amos-6 satellite being fully operational. Supposedly, the buyer only wants to pay $190 million now. They may also end up backing out.

Someone else's launch going badly can also be bad for your company. The explosion that took out Amos-6 also damaged the pad and threw off SpaceX's schedule (which was already oversubscribed). Inmarsat was required by the EU to start using their spectrum by a given deadline, which they ended up missing. Theoretically, the EU could take away their spectrum allocation (although they probably won't). Inmarsat did end up having to buy a launch with another provider though, which probably cost them a ton of money[3].

I don't doubt that Russia is swimming in corruption and that it makes a lot of things more difficult. But to say that they're incapable of a major engineering project, even if Putin takes a personal interest? I think you'll need to justify that.

Well if you are aware of a major successful project bring an example. It would be hard to argue that Putin is not personally interested in any of the major military projects yet from Armata to fighter jets that even long term customers like India are abandoning due to horrible quality does not look like his personal interest helps much.

Arianespace is their biggest competitor, they are the de facto rulers of the commercial launch market, with SpaceX hot on their heels. The Ariane 5 launches twin payloads about 7 times a year, for a total of about 14 total spacecraft launches per year. SpaceX is about at a similar cadence but has yet to hit the overall schedule and mission reliability figures that Arianespace has achieved so it's still a bit of a rac…

The one part of the market where they will continue to see competition is for those payloads/trajectories where there is no way to land the booster.

And remember even a booster with a 10-launch lifetime can do a reusable-priced expendable launch on the final flight before "retirement" :)
