This time, they launched without the landing legs, but since they are still testing above water that does not matter a lot. Deploying the legs and soft landing on water have been tried successfully already, so I imagine they could test other things like partially flying back to the launching site, fuel permitting. The twitters are silent, so far, however.

At the NASA pre-launch press conference, Hans Koenigsmann said that they would be doing the first boost back burn, as well as a re-entry and "landing" burn. At the SpaceX CRS-4 Post Launch Briefing he said that it looked like all the burns wear successful, but they had to wait for the boat that collected telemetry to return.

I feel like I've seen some confirmation on good telemetry on twitter, but I can't find it now and this story is old enough that no one will likely see my post anyway...

SpaceX is already in the process of man-rating Dragon. NASA is, apparently, perfectly willing to let SpaceX run through the man-rating checklists as long as NASA doesn't have to pay for it.

This is true, you can lose funding but continue to participate in meeting various milestones. I believe that Blue Origin already falls into this category.

But NASAs "manned rating" only applies to flying NASA missions. NASA has no control over non-NASA missions - think Bigelow private funded space stations, MarsOne, etc...

There is no purpose to manned spaceflight.

If we want to settle Mars and generally expand into space, you need manned spaceflight. I know not everyone thinks that is important. But some people, myself included, do believe that is a worthwhile endeavor.

The scientific return comes from unmanned spaceflight. Manned spaceflights are stunts to keep the pork flowing to Congressionally powerful districts. There is nothing done by manned spaceflight that could not be done unmanned for one tenth or one hundredth the cost as an unmanned mission.

This is true, if the only reason for spaceflight is pure science. I am a huge fan of pure science, but I don't think that is the only purpose of spaceflight.

The problem is that NASA is run by ex-flyboys and astronauts. There is an internal battle between the manned spaceflight directorate and the science directorate (NASA/JPL). The former do maned pork and are always trying to steal funds away from the science guys. The manned fighter-jocks tried to kill planetary science many times, the last time was earlier this year. At one point they allocated more for a Space Toilet (30 mil) than they did for a Europa mission (15 mi). NASA needs a shakeup and the science guys need equal control at the top.

I think the bigger problem is that NASA funding (and therefore mission selection) is completely hostage to election cycles of Congressmen, Senators and the President. It's impossible to have a coherent long term plan.

While commercial corporations interested in launching their product into space may go with the best price/performance ratio, the chances of a USG contract even being written in a vendor-agnostic manner are slim. It's all about whose district or state the potential money will go.

Actually the commercial cargo and commercial crew contracts were written specifically to avoid those sorts of shenanigans. Congress has no say in who wins. Of course Senators and Congressmen are still trying to play games for their constituents (like the latest accusations that SpaceX has had unreasonable flight anomalies from senators in competitors states.) They are also trying to starve the entire program of money specifically because it is a threat to ULA. But all in all, the commercial contract approach is a huge improvement and it looks likely that SpaceX or SNC will win the bid (possibly both, if Congress will fund that. It makes sense to have two launch providers so an "incident" doesn't completely halt flights - like the shuttle disasters did.) Funny that the article doesn't even mention SNA (Dream Chaser.)

One of the reasons that SpaceX and/or SNC will likely win is that they both are dedicated to developing their spacecraft regardless of the outcome of the bidding process. Losing the contract would slow development, but not stop it. Where as Boeing, with all their money and resources, has publicly stated that they will mothball development if they don't win. (This is a strange attitude given the fact Boeing and Bigelow are partners in the commercial crew competition.) One of the criteria for winning is the commercial viability of the spacecraft. NASA does not want to be in the position of being financially black mailed with threats like "we need more money or we can't survive". The fact that SpaceX and SNC are pursuing non-NASA missions is seen as a major advantage according to insiders.

We Americans need to remember what war is and what it is not. It's not about winning hearts and minds, it's about fragging hearts and minds. If we kept this in mind we would resume winning wars again ala 1945, but there are too many bleeding heart liberals who couldn't handle this brutal variety of truth. Therefore those who can't handle this sort of truth should STFU re: foreign intervention.

Maybe a better lesson would be not to invade countries that pose no serious threat to the US and not to believe the fantasy that if you destroy a country's infrastructure that a thankful democracy will emerge from a sea of sectarian hatred.

I'd rather have seas 30 feet higher in 100-300 years and living with (say) 2314-year tech than current seas and year 2200 tech in 2314...or 2214. Hech, a 10% slowdown, miserably easy for an overbearing government to achieve, would yield a 30 year delta at the end. Hell, I'd rather have 2014 tech than 1984-tech.

Proposed solutions matter and should be judged in the context of tech advancement, or lack thereof. That's what saves lives.

You seem to be creating a false dichotomy, implying that addressing climate change would slow technological growth. Modernizing the power grid, storing energy from non-greenhouse gas generating power sources, better power management, electric cars, solar power, nuclear power, fusion, etc are all technologies that would make life better. Besides reducing green house gasses, energy ultimately becomes cheaper and pollution is reduced worldwide.

Sounds horrible. It's interesting to me that many opposed to AGW (not saying you), complain about the AGW alarmists, but they themselves are economic alarmists. As if addressing climate change will destroy the economy.

SpaceX is not competing with NASA, because NASA doesn't make rockets. NASA has input on the design requirements, but all the real work is done by private contractors, like Lockheed and Boeing. SpaceX is just a new contractor and they operate just like the others. They have some interesting new engineering approaches that may reduce costs, but it's not any fundamentally new business model.

Actually, it is a fundamentally different business model. You are correct that it was always private companies that did the final design and construction of the rockets, but historically Congress forced many decisions on NASA based largely on spreading the money around. For instance, NASA wanted the Space Shuttle to use liquid fueled boosters, but Congress insisted on the SRBs specifically so Thiokol Corporation of Utah would get the business. The same thing is happening with the STS under development now. Congress is forcing NASA to use Shuttle components in the first generation STS specifically to funnel money into certain congressional districts. Under the non-commercial contracts, Congress and NASA actually make design decisions that may not be optimum from an engineering perspective.

The rules under which SpaceX performs NASA missions, are much different. NASA does not get involved in the design of the rocket/spacecraft beyond listing requirements that must be met. Some seed money is provided, for companies that win bids to compete. But ultimately the winners are paid a fixed price - which is also a big difference. Historically, these contracts were cost plus. This new approach does appear to be saving money and it is also leading to competing designs which is interesting as well. For instance with commercial crew, Boeing is building a fairly conventual capsule that lands under parachute, Sierra Nevada is building a lifting body that will reenter and glide like the shuttle, and SpaceX is building a capsule that will land propulsively (parahutes will only be deployed if there is a malfunction in the engines.)

Yes, there are delays and difficulties with both Tesla and SpaceX. Now show me someone that is building more compelling electric cars than Tesla. Owner's of Tesla's love them. If it wasn't a good car, it wouldn't have the satisfaction ratings it does. Car magazines wouldn't be raving about it.

Probably not, if it has a combination lock. With a warrant they can always break open a physical safe. But that method does not compel the owner to do anything.

Interestingly that article seems to imply you can be compelled to hand over a physical key, but not a combination as it is "contents of the mind." So if the key is stored on physical media it may not be considered "contents of the mind." And if it's stored in your mind, it can probably be brute forced fairly quickly.
