Actually, an effective system would DETER attacks. Instead, Iron Dome seems to perpetuate the conflict. Need to find a way to deter attacks.
You're talking about radar-guided counter-battery fire. Well, Israel could most certainly do that, but prepare for the shit hitting the fan it they ever do that.
This is what an unintercepted impact looks like
Hey, that looks conspicuously like my room! Damned Hamas. I knew there was something wrong when no amount of tidying up could make any marked difference in neatness.
There is no scientifically valid way to rule out life forms which are unlike our own
I'm pretty sure there are ways to constrain the range of possibilities. One obvious thing is that no life forms will most likely be based on xenon or gold because these elements don't really form the same kind of a wide range of interesting compounds that carbon does. The laws of physics (and chemistry) are the same pretty much everywhere, and just because our brains (and computers) are incapable of reaching more significant conclusions on this issue at this very moment doesn't mean that it's going to stay like that forever.
Accurate if you only want to emulate the 68000-based versions. Anything with cache (020 or higher) and timings are off.
But is that even important? Caches themselves introduce execution trace non-determinism (certainly in the presence of interrupts and multitasking) because you don't know in advance if the memory reference is going to hit or miss. The program can't rely on timings in those cases (it's my understanding that this is why Cortex-M for real-time control doesn't have any caches at all - if you really have to care about worst-case behavior, trying to improve the average case may be pointless for many applications).
Alternatively, you could just clarify what you meant: maybe you didn't consider the possibility that the astronaut could be female or transgender. Or possibly you were using 'he' as the gender neutral pronoun - which hasn't been the convention in most english speaking countries for many years.
Actually, it's been the convention in Indo-European languages for a millennium or so; in fact, the structure of many of these allows for no other choice (Slavic languages, German, French etc.), and many English speakers - if not most - are L2 speakers for which this is the most compatible and the only natural alternative (the "uncanny valley" subproblem of interference in interlanguage fossilization). As a bonus, with the rapidly increasing number of perceived and recognized psychological genders (not the linguistic ones) on the very short timescale of the few recent decades, there's no need to rewrite texts and textbooks (considering that the purpose of written texts is to span not only vast amounts of space but of time as well); one could easily argue that "improvements" of limited scope such as your "he or she", while attempting to sound inclusive (for whatever strange reason some people might perceive it that way) are, for example, distinctly interphobic - which, again, would be a social construct with limited longevity compared to the potential timelessness of any written text.
Or send a machine which avoids the need to choose which rock get's "poked"
And how do you propose that a machine like this should work? By poking into everything, or by giving it a brain we don't have?
Given the human body is notoriously unreliable and can only self repair minor injuries, I don't think the 'self repair' option is really viable either.
So humans won't be able to repair them, because you're not going to send them, and you're arguing the case for machines repairing themselves is equally bad? So what *is* your proposed solution? The "disposable camera" model? That really doesn't scale very well.
(It is also interesting to observe how the "notoriously unreliable" human body of yours actually deals with some space-related conditions such as moderately intense radiation actually better than the majority of our technology, which is prone to hard errors, and if scaled to the cognitive capacity of the human brain would fare even worse.)
He or she, I assume you mean.
I'm a speaker of an Indo-European language; do the math. Regarding the rest, well, then replace the geologists with mission planners of any other kind, capable of deciding into which rock the machine should poke next time. Or devise a way to make the machines maintain themselves far away from Earth, because that's another thing humans would be able to provide on site and current technology doesn't.
