Newt

Cleaned up now.

Rubber, Spongy, Fist, you say? I personally have a particular affinity for tungsten steel mesh fists, but, I suppose, what ever works, works:wink:. --- And Salutations! Welcome to the forums, and good luck landing intact (more or less).

Greetings from Earth! Welcome to the forum. Also, interesting lander you have there. . . do you meet back up with a return vehicle in orbit?

This does not sound to me like "Design a Mars Program and Vehicle". More like a request for some system to be designed as a sustainable, independant, and feasible tool for such a mission to include. I would more imagine to tackle it as, say, answering a question about basic life on Mars; 'What happens when the wrench breaks and I need to use it?' or 'How do I clean dust off my boots?', not such a grand, full mission as is being hinted at here.

.18 I did a bit of a progression as far as landing craft, first vehicle was an impactor, then an orbiter, then a soft lander, finally, the manned vehicle. My impactor was pretty small and basic, but as I worked along to the manned vehicle, designs, grew, shall we say. We launched to the space station. Four crew were already present on the station in LKO, as was the command module of the four part lunar ship. The new crew, three of the six for the Mun vehicle, boarded, partied, and looked through the windows, as the massive fuel tank was launched at sunset. Later came a larger habitat, and the lander itself, as well as three new crew members in a fuel carrying craft. After all was arranged, all the Kerbalnauts at their stations, the commander sitting looked out the window over the solar areas, and detatched, firing the cold gas thrusters slightly to pushe away from the station, comprable in size to the component that had just left it. The hours went by, and the station grew smaller in the windows of the ship. As we got into position, the liquid fuel engine was fired, setting up a course for a 10 km orbit of the Mun, or there about. This proceeded well, a few days later the first landing pair climbed into their vehicle, detatched, and fired retrograde, slowly falling away from their comrades. Fuel was getting short, but not so much so that it posed a problem. We landed on the rim of a large crater, and took what turned out to be too liberal of a flight with the MMU, 10km of walking uphil is slow. Launch back was fairly good, and the docking strained but acheived. It seemed the mission was over, but still, we needed to wait for the Kerbin return leg. THat happened some months later, if I recall correctly, after anoher few Mun landings (everyone got their turn).

Regarding that water vapor versus bright exposed dust question, I am increasingly thinking that there seems, weel, to be a good argument for water/ice to be present, and those spots, look not inconsistent with being caused by the same thing. As Frida Space noted, we have seen water plumes at Ceres. From what I have heard, these plumes coincide in position with the Great White Spots. Sure, they could be simply the result of mass wasting on the central peak, and sure they could be somehow analogous to crater rays on Moon; both of these explanations make sense. But there seems to be rather a lot that suggests these may be, really, amazingly, the result of some sort of eruption. This does not mean I think they are ice, it could be deposited salt, or some other substance that was dropped out by a water eruption. There is much reason to doubt that ice could last on the surface for long, as has already been noted. This explanation could also be consistent with the material looking like ejecta; it is--just not from an imapct crater.

Yes, that would have a similar effect, but not at the same scale. The original mention was to use the Earth and Mars based telescopes as an array. Being on Mars would have an advantage of distance as well as noise. That said, there are tons of places that are easier to get to than Mars. Why build a telescope on a planet (often, there is, well, this big lump of rock that makes it hard to look at half the sky, you know), when you could build in Earth Sun L5, for instance? more reliably distance, no need for large return rockets that can blast through an atmosphere, no wait for launch windows, and a huge visible mass of sky avaliable at all times. And you could build it so much bigger. This is one thing that too few people seem to notice. Many people, Musk among them, make suggestions of possibilities, and, at least in the case of Musk, many people take those possibilities to be statements of commitment (or visions from an oracle). If all such statements were truth, we would have landed on Mars in the 70's, been on massive space colonies in the 90's, launched some interstellar spacecraft by now.... SpaceX has acheived some things, but it seems that at present one of their cheif products is hype. I do not disagree that it is doable, but I am doubtful that it shall be done. As always, there are many possible things to do, and only a few options are ever actually done. Could we have landed humans on Mars in 1980? If we started activley after Apollo, I have very little doubt that it was possible. But it was halted by lack of will, and there is little reason at present to beleive that, at this time, SpaceX is not proven to be capable of completing this very lofty goal. The main issues are not technical, rather political and economical.

Seldom watching the television here (USA), I remember them from when I was younger. I am not sure they were creepy, or scary really, just, interesting. Of course, I never received any bad memories to associate with them--all the ones I ever saw were tests. More recently, during the last few years, I have received them via radio, but I think I always understood them. They more prompted informed responses then alarm. Mostly they have been about serious weather conditions, quarter size hail, for example, comming in fifteen minutes (a correct prediction), or a really serious fire, when my house was kept under pre-evacuation notice for several days .We needed to be able to be gone in one quarter hour, but left voluntarily, as did most people nearby--the smoke was awful at my house, even when it cleared enough to return and it rained burned leaves and ash all over town. That was a fun birthday . Once a tornado warning was issued. I live in Arizona, and that was pretty alarming, at least one house in a nearby town lost its roof as part of that storm, though I was not directly affected by other than my caution and that of others. Overall, I have generally found them quite helpful. At worst they give information that I already have, but rather need anyway. Regarding the alarm sounds, that is very interesting, they sounded like possibly that sort of transmission, but I had never looked into it very much. And about duck and cover, of course there is the possibility that you will be vaporized, crushed, smashed by flying shrapnel, killed by poisoned water, or fall victim to any other of a quite diverse set of possible fates derived directly from a nuclear attack on a city, and perhaps, 'duck and cover' will reduce the chance of death/serious injury somewhat, versus staying at your desk (or wherever) by creating a small sheilded area. But from my understanding, a large amount of the 'saftey' it provided, was, in addition to the feeling that something can be done in such an event, is drill into people's minds an objective for such a blast that says nothing about looking at the explosion through a window. The fact that probably, so many people would rush to areas where they could see the cloud of the explosion and the missile tail if applicable would almost certainly increase the number of casualties by rather a large degree, as the shockwave would proceed to shower people with shards of glass and smash them to the ground with immense force. It seems that many peoples base inclination would be to place themselves, without thinking, in a place of serious danger. Perhaps 'duck and cover' does not make you particularly safe, but it should protect you from your own actions.

Congragulations for both of those. And happy 1400th post, too. Several of my freinds are also graduating from their universities, for me, though, I am simply releived to be done with finals, for the time being....

At 247 posts, I am ranked at 1356 (by the list), tied with rather a number of people whom I shall promptly pass as I hit this little button at the bottom of my screen. @Ethan: The list was linked earlier, but here it is again with the settings to go by post count. Wow. 10 posts in several years. I am impressed incredibly. The reserve that that member must have, is astounding. I think I got past 10 posts in my first day here, talking about the Orion test flight. NOW RANKED AT 1351

If I understand you correctly, NO. Colmo?

Did anyone else make it to one of the I C Ceres events Saturday? I went to one talk and poster session with a geologist from the Dawn team, and got to see some newer Images from RC3. There were several large basins visible in higher detail, one, notably, appeared to have been resurfaced by some force (cryovolcanism?), and another which was the source of the large cracks visible on the surface. The person I spoke with was suggesting that possibly these cracks (some of which run very near to the prominent bright spots) could be the source of the eruption that was visible with the Herschel telescope at the site of the prominent bright marks in the crater. Another geologist I spoke to was under the impression that whatever these were, it was probably not ice, as infared images of the site showed little temperature change to indicate that, but the scientist I spoke to Saturday was of the opinion that the resolution of that instrument remains too low to say with confidence. A new image of the bright spot also shows that the spot not on the crater peak (which is still too saturated to see detail at) is, in fact, several smaller spots clustered together. As far as general topography, the place is starting to look very interesting as well, lumpy and strange in ways that are not connected clearly to cratering, perhaps indiciative of further volcanism in the past, but I am not certain. This may connect to that tall mountain posted be Frida Space. There was other information (and images as well) that I can try to answer questions on if anyone wants to hear (read?).

Greetings! I hope your time here is enjoable.

What even is this. . . I thought my username was a random pairing of pronouncable letters. Turns out 'newt' is a type of animal: (please note that I do, in fact, know what a Newt is)

My highschool was small, but we had a prom. I stayed up really late. Looking through some telescopes with friends. It was not really prom-like, but I have never really been one for that sort of thing, anyway.

Just for argument, the word used was 'structure', not 'building', and probably solid blocks of stacked stones are a structure. But this is really neat. It seems somewhat similar to the previously remade Library of Alexandria, of course, that was defenitly not a replica of the original. My main concern wouldbe the fact that it remains on the original site. I suppose they shall probably be careful about excavating and not destroying.

Well, some of us evil robots (so called) have succeeded in getting past it . Welcome, Highspeedsteel!

I am with many people: VISIT EVERYWHERE! But, I will also note, as others have, the Uranus/Neptune, have been left out, rather, since thier inclusion on Voyager II, because everything worked out nicley and they got to add them. These places are fascinating, Triton, is simply bizzare, some of the other qualities of difference between the 'Ice Giants' and the larger partners, also deserve to be further explored. Uranus, always shown as, basically nothing on a greenish haze, may have more clouds to it as well (not that plain is not interesting), et cetera. These areas were seen in a tiny, tiny window of time by a vehicle not built specially to go to them. Sending orbiters there could do quite a bit, and if I could with my magical dust of political will cause one space mission to be pursued, it would probably be one of these.

If you breath it it is rather dangerous, yes. Well, that just means it it not as bad as it could be. The astronauts breathed some Lunar dust, defenitly, but it was over just a few days, in limited amounts. If you lived on the Moon, for months or years, always walking into the main base habitat area with your dusty suit and boots right by where you sleep, more problems might manifest. This however, is talking about melting it. Part of the danger is from the extremely fine particles, when melted the stuff should be pretty safe.

47. Kial la suno ne helas, cxi tiam?

Greetings Parane, welcome to the forms!

If this happens, it is not going to happen for a while, not completley at leastm not even mostly. It remains, and likely will for rather a while, generally far cheaper to employ humans for many jobs. This gets into some of the migrant labour in Southwest USA, which is often sorely underpaid, as well as the common trend of using manufacturing abilities of countries where wages can be lower, working conditions worse, and costs cheaper. If Apple, Nike, and the many, many other companies that engage in these practices wanted to, they might could switch over to having a largley autonomous workforce, they could, but it remains practical, and prefereable for them not to. Humans will still have roles in many places for a long time, if you set the wages low enough. If there is no other choice, people will take nearly any employment, if it means food and security.

My name is not Ethan. But, I can answer to it, if you like. Zekes.

Farewell, for now, Yukon.

It is not just a problem of 'remagnetizing' Mars--part of the reason that Earth/Mercury/Jupiter have strong magnetic feilds is their liquid cores. Mars would not really work the same way, that is why it does not have a magnetic feild of not at this time. This does not mean you could not do it, of course, and already the assumptions of this thread put us well into science fiction. But I am not sure how practical it would be to simply run energy into it (I have not studied planetary magnetic feilds much, so take my undeveloped opinion with skeptecism).
