Why is that a problem, are you concerned about surface gravity? Assuming a similar density to Earth, it would only be ~1.3 Earth gravities, since F_g falls off with r^2.

Addendum: I don't know if this was mentioned in the article (yay laziness!), but most spacecraft are merely cleaned, not sterilized. Avoiding contamination is important for interplanetary missions, but not so much for something that's going to stay in Earth orbit or burn up in its atmosphere.

You are right of course, but that's not really a central part of this particular story. Hydrogen fuel cells are not internal combustion engines.

I know you are kidding, but I'll just add a couple points: 1) The Earth's orbit is quite stable; the seasons are caused by the fact that the Earth's axis of rotation is inclined its orbit normal. To make it an equinox year-round, fix that. 2) To slightly increase the period of the Earth's orbit around the Sun, we actually need to speed it up! Orbital mechanics are not always intuitive :)

Let me fix that for you: why is movie rental supposed to work? Just because a business model made sense at one point for a particular medium does that mean that it will continue to do so moving forward, nor that artificial restrictions should be placed on innovation to force existing business models to soldier on.

Nothing has been proven. Scientists have long had a theory about how the Sun powers itself. That theory can be used to make predictions, such as the type of neutrinos that we should expect to see emanating from the Sun. An experiment was devised to test such a prediction, the hypothesis being that this type of neutrinos is being produced and thus will be detected. Having performed the experiment, we see that the results match what we expected, validating the hypothesis. This is important and significant, and it provides further evidence suggesting the widely accepted theory is accurate, but it does not -- nor can it -- constitute a proof.

The other interesting result would be if the expected neutrino type was not detected by this experiment, invalidating the hypothesis. This would raise further questions such as: is there some other mechanism powering the Sun? Is there something deficient in our understanding of neutrinos that prevented us from detecting them despite them being there? Was there an error in the test setup (i.e. is it repeatable by other parties)?

Just pointing out that SpaceX's manned Dragon capsule won't have an escape tower; the launch escape system is a set of eight SuperDraco thrusters, which will also be used for soft ground landing after normal flights.

Is there an open-source FPGA design/implementation that you can run this on? Otherwise it's not really open-hardware all the way down, is it..

You don't need a downed aircraft to do that kind of research though, you can just go out and look for something, maybe something that isn't even there.

Using your number of 0.001% probability of this crash being something technical, and my estimated value of MH370 of $2.6B, then $26,000. The 777 has a lot of flight hours; if there's a technical problem with it, its a corner-case quirk, not a fundamental design issue. Maybe it doesn't sit well with you, but it is not reasonable to expect 100% safety from any system -- it would be prohibitively expensive.
