    The V1 "buzz bomb" in world war two had control surfaces (controlled IIRC by a combination of clockwork timers and a mechanical gyrocompass) and an air-breathing engine. So, was it an aircraft or a missile.

    Missiles go from point A to point B. Craft take something from point A to point B, deliver it, and are then ready for use to go to point C. Like an ox-cart, instead of an arrow. Does that work better as a distinction?

    It doesn't convince me either. Looking at the video (linked to from the original article)it looks as if his thesis is more about the effects of basally-detached slabs (subduction from a spreading centre in the region of the Tharsis volcanos?) generating "V-shaped" fault patterns. But that would have the sense of movement on Vallis Marineris in the opposite sense to what is marked on the press-release.

    I'm not going to hold my breath looking to see what actually comes out of this. Looks like a pretty poor press release to me, and I'm not inclined to by the paper. If it flies, there'll be something in the public domain eventually.

    "Assumed" - no.

    About a decade ago, magnetometry produced weak evidence for magnetic "striping" running more-or-less parallel to the (present) Martian equator. That certainly stimulated much thinking about the tectonics of Mars (plate tectonics, overturn tectonics, hotspot tectonics?). But that's an open debate on a changing evidence base, not an assumption.

    So, four out of the classical nine planets (Venus, Earth, Uranus, Pluto) got "fucked over" by something late in their formation, leading to double-planets/ giant moons (Earth-Moon ; Pluto-Charon) or high axial tilts (Venus, Uranus).

    Four out of nine is nearly a majority, isn't it?

    Breaking News! Mercury has been mantle stripped. It's over-dense for it's size, and looks like the core of a somewhat larger terrestrial planet which has had much of it's mantle torn off. Which is one of the things that a giant impact can do.

    So that makes five out of nine.

    Looks to me like giant impacts may be "normal" in the formation of planets.

    Venus is a very interesting question.

    It certainly has lava flows (from the radar data mentioned elsewhere). It has volcano-like (though not very like Earth volcanos) structures. But there's very little evidence for current activity. On the other hand, crater counts (even accounting for the much thicker atmosphere) suggest that the visible surface is all younger than the average of the Earth's continents. But on the gripping hand, older than the average of the Earth's oceans.

    No-one knows what is going on there. One of the more interesting (to me, as a geologist) suggestions is that Venus has lost the water from it's surface which on Earth would get partly subducted into the mantle, leading to a stiffer mantle on Venus, and thus differences in the mode of heat transport on Venus. (Earth has a few 10ths of a percent of water in it's mantle.)

    But anyone who claims "this is the solution" is almost certainly wrong. There are different theories, and all have some good points and some bad points. Take your pick.

    99% of brickings are the result of people doing stuff that the manufacturer did not intend for you to do

    In that case, that should happen with deep space probes quite a lot.

    ... or it would do, if the manufacturers and the users weren't the same group. Or, for the likes of NASA, the manufacturers of the flight hardware computers and the manufacturers of the flight software weren't two groups of the same organisation, both of whom would take equal accountability for a failure like this. (And probably work in the same building complex, if not the same office block.)

    Which is the norm for deep space devices, wherever they come from.

    Before someone points it out, they do buy in the radiation-hardened processors from an outside supplier. But that is one of the reasons that they are very conservative about which processors they use, to only use processors whose design they understand in great depth.
    In a related recent thread there was discussion about why the imagers on MSL used a 2MPixel sensor. One of the points that didn't get stressed much in that was that all of the imagers on MSL use the same sensor, whether it be a science-imaging sensor, a hazard-hunting imager, or a long-range viewing sensor. They all use the same sensor, because it is a sensor that the JPL imaging team understand well.
    As a different example of the same logic, they chose to not build a zoom lens for the long-range sensor (twice ; they started and stopped the zoom lens programme twice) because they couldn't find a way to build a zoom lens without using "wet" lubrication, and they don't have confidence in the behaviour of wet lubricants under Mars surface conditions, and couldn't afford the weight and power to heat the lens to non-Mars surface conditions. (Which kind-of begs the question of couldn't they put multiple fixed-focal length lenses onto a turret ; but maybe a turret would also have required "wet" lubrication?)

    64 GIGABYTES A DAY?

    Hmmm,

    My camera takes RAW images at about 5MB each ; 3-4MB for JPEGS (which I wouldn't bother trying to work with in any important sense). Say a modern camera takes RAWs at 10MB apiece, that would be 6400-ish images per day. For a 12 hour working day ... that is 534 images per hour; 6 seconds per image.

    It's extremely fast, allowing almost no time for composition, thinking about exposures, avoiding flare and glare. Or for changing cards in the camera or administrivia. Or for ... well the gal must be using a porta-pissa strapped to his waist and adult-sized nappies (yes, they exist). But it is just about credible. Say, the person who is taking continuity photos for a movie production. No, that doesn't work ; they take shots at start and end of a take, and of the actors costumed on set, but not normally during the shoot. But it's extremely fast shooting and therefore must be highly automated with little user input.

    Space imagers don't have anything like that bandwidth, due to Spaces being really big ; mind-bogglingly incomprehensibly big (#include . The state of the art (for space imagery) new Mars rover ("MSL") has about 1/4 GB per day/sol of bandwidth available to it. What they do do is use filters appropriately, of carefully targeted shots. Which is precisely NOT comparable with what the OP is doing at 6 seconds per image. For MSL, it's probably more like 5 minutes discussion (on Earth, half-dozen people in meeting) per image.

It may even be as little as 13% (IANA-foodie, as I said a few moments ago). In your "pork goods" category you'll see the percentages going down, and the quality of the ingredients going down, as the price (for a set quality/ quantity) goes up.
