      An Italian astronomer named Schiaparelli created some of the first maps of Mars. He named features using words from biblical and mythical geography. Some of these names, such as Argyre, Hellas, and Tempe, are still used on maps and globes of Mars.

      In the 1970s, after the Mariner spacecraft flew by Mars, many new images were returned to Earth. A special group of people was formed to decide on names for the newly discovered features. This group also set up rules for naming future discoveries.

      All features on Mars have two names. The first is a formal name following the international rules that have been established. The other is a geologic name. The second name tells us what type of geologic feature it is. Following are some examples of geologic names:

      • Mons: mountain
      • Crater: circular depression
      • Dorsum: ridge
      • Planum: plateau or high plain
      • Fossa: depression (hole)
      • Valles: valley

      For example, Olympus Mons is a mountain formed by a volcano. It is named after Mount Olympus in Greece. Sometimes the name order is reversed. For example, in Valles Marineris, the geologic name comes first. Valles Marineris is a valley named after the Mariner spacecraft that first flew by Mars.

      Anyone can submit a name for a specific feature on Mars! The group meets once each year to consider appropriate names. If you would like to suggest a name for a feature on Mars, send your suggestion to the U.S. Geological Survey, Branch of Astrogeology, Room 409, 2255 N. Gemini Drive, Flagstaff, AZ 86001.

      Rules for Naming Martian Features

      Large craters are named after deceased scientists who have contributed to the study of Mars.

      • Gusev (Maturei M., 1826-1866, Russian astronomer)
      • Lowell (Percival, 1855-1916, American astronomer)

      Small craters are named for villages and towns of the world with populations less than 100,000.

      • Aspen (Town in Colorado, USA)
      • Bira (Town in Russia)
      • Isil (Town in Spain)
      • Jama (Town in Tunisia)
      • Kakori (Town in India)

      Large valleys are named for the word used for Mars in various languages of the world.

      • Ares Vallis (word for Mars in Greek)
      • Mangala Valles (word for Mars in Sanskrit)
      • Marte Vallis (word for Mars in Spanish)
      • Mawrth Vallis (word for Mars in Welsh)
      • Nirgal Vallis (word for Mars in Babylonian)
      • Tiu Vallis (word for Mars in Old English)

      Small valleys are named for classical or modern names of rivers.

      • Indus Vallis (river in Pakistan)
      • Naktong Vallis (river in Korea)
      • Warrego Valles (river in Australia)

      All other features retain the names given by Schiaparelli or Antoniadi, another Italian astronomer.

      • Amazonis Planitia (classical name)
      • Libya Mons (classical name)
      • Olympus Mons (classical name)

      Rules for Naming Craters

      Naming rules exist for most features on planets, moons, and asteroids. The following are the regulations for craters:

      • Craters on Mercury are named after famous deceased artists, musicians, painters, or authors.
      • Large craters on Venus are named after famous women.
      • Small craters on Venus are given common female first names.
      • Large craters on Earth's moon are named after famous deceased scientists, scholars, or artists.
      • Small craters on the moon are given common first names.
      • Craters on Jupiter's moon Europa are given names of Celtic gods and heroes.
      • Craters on Jupiter's moon Ganymede are named for gods and heroes of the ancient Fertile Crescent people.
      • Craters on the asteroid Ida are named for caverns and grottos of the world.

        I think there is life there and the U.S. government thinks we can't handle the truth, so hence we don't go.

        I suspect there is life, too. Of course I'm just an armchair scientist and this is just my humble opinion based on what I've read. Further, I suspect that "the government" (people, mostly) reads the same articles as you and is privy to the same data as you. That is what is great about living in an open society.
        I don't think there is any conspiracy keeping us from "handling" the truth. Why, you ask? Clinton couldn't keep things mum about getting blow jobs on the floor of the oval office. Nixon couldn't keep things mum about having broken into his political opponents' headquarters. Reagan couldn't keep things mum about having sold weapons to the Iranians to fund a terrorist army in Central America. Bush is having a problem keeping a lid on using forged documentation as a pretext for war (and WHO, pray tell, would forge such a thing anyway?) THESE are secrets that people would certainly have given anything to keep. And still they got out. Because "the government" isn't "the government" -- it is a bunch of people, all with agendas, all using what they know to their advantage when they can. Welcome to the wonderfully messy world of democracy.

        Anyway, I'm getting ahead of myself, the above wasn't my point -- but I had to debunk the tinfoil hat wearers in this crowd at least a little...

        I live in Minnesota, land of 10,000 lakes. Most of those lakes are becoming unswimmable because of something called Eurasian Milfoil. Milfoil is a weed grows in lakes. It grows fast. Several feet a day. It was accidentally introduced to America in the early 1900s. It wasn't native but there isn't anything in the lakes on THIS side of the pond that like to eat it so it quickly clogs the entire lake.

        And it spreads. From lake-to-lake. Boaters. Fish. Whatever. It finds a way to find a new lake that it can call home and it does. And once it does: Game over everyone else. Not instantly. And there is still a lake there. There is still water. And fish. But now there is a stinky gross weed clogging the entire lake for most of the summer, too. Not really enjoyable. A lot of nose holding and "I remember when we could swim in the lakes without all these weeds here" going on.

        Hold on... I'm still building here. And I'm almost to the good stuff. (wait for it...)

        My point is this: Let's say there is life on Mars. There won't be cows or zebra or fish or anything like that. No, there will be microbes. Tiny little red life forms that live with almost no oxygen and no water in the freezing cold, bombarded by radiation. Hmmmm... I'm not sure about the rest of you, but the prospect of bringing something that battle-hardened back to Earth to study does not inspire confidence in me. Chernobyl, Enron, Challenger, Columbia, Africanized Killer Bees, cross-pollinated genetically engineered corn... bad things happen unexpectedly. Stuff LEAKS. Again, no conspiracy needed, just the good old second law of thermodynamics coupled with that one law discovered by Murphy making a real world demonstration.

        As I said in the subject of my post: I, for one, am glad we aren't going to Mars. We don't need any more milfoil, at least for now. Frankly, I'd be happy to see us wait a few thousand years. For real. Red mold everywhere? Yuck.

The recognition they would receive from pulling something like this off would be worth any investment to them.

            This is a little silly. The US would/could have no problem funding it as compared to China. We are orders of magnitude wealthier than the Chinese. We can fund things we don't really care about at levels as high, or perhaps even higher, than they can fund things that are their central goals.

          The trouble with extrapolating that battle hardened microbes will displace all competing microbes, is to overlook some of the main features of evolution. There are enough desolate places on Earth to breed such creatures, and they are populated by such creatures, but these hardy creatures don't displace the E-Coli in your gut. Why not? The adaptations to flourish in harsh environments depend of chemical tricks and adaptations that only work in harsh environments. Your lake weed example actually illustrates this point. These weeds evolved in very similar lake environments, and exploded in population only from lack of natural predators and parasites. Cactuses are very "battle hardened" plants, and yet are very unlikely to take over your Minnesota lakes.

          Should someone intentionally introduce Martian microbes to similar extreme environments here on Earth, we might see something similar, but contained within those extreme environments, and having little impact on that portion of the biosphere we usually experience. Sure it would have some environmental impact, but likely not disastrous. Most likely it would integrate with the local ecology, though perhaps not in way we would like. Esthetically you feel your lakes have suffered by introduction of a weed that wasn't native to the environment 100 years ago, but it's not the end of the world. Only evolution in action. The contamination of these lakes could have happened naturally, and a similar adaptation cycle would have occurred. I suspect introduction of alien species has little true long term impact on the biosphere. Which is not to say such disruptions are desirable, or don't have severe local impacts, aesthetically and economically.

          I would say it is likely we can bring back samples and contain them.
          If we have an accident, it is unlikely the microbes will spread because they are not adapted to the immediate environment.
          Should they somehow gain a toehold in an environment favorable to them, they will likely integrate with the ecology in some way, not totally displace it.
          All and all, I think these points argue well for taking the risk of sample return missions, the reward being unknown insights into biological processes.

          One final aside, I would use the International Space Station as a first containment stop for a sample return mission, and have written to NASA on this point. Not because is greatly enhances safety (and it probably adds to cost), but because it gives psychological reassurance to the general populace that NASA is doing everything to ensure safety, and it gives the ISS a true mission.

We tend to think of organisms that live in environments inimical to human life -- deserts, the deep ocean, polar regions, etc. -- as "tougher" than those that live in environments we consider pleasant.

    Schiaperelli is also accidentally responsible for a lot of postulating about the existence of intelligent life on Mars. He observed dark "channels" possibly caused by natural water flow. In Italian, they are called, "Canali" and were mistranslated into English as "canals" which would tilt most folks' thinking in the direction of intelligence on Mars.
    • Actually, many of the channels he observed were optical illusions caused by the brain trying to play "connect the dots", which is why on many of the early hand-drawn maps you see such perfectly straight lines criss-crossing the surface.
      • The Pan Am ad from the 70s showed America picked out in bright city lights, all through from coast to coast, while canada and mexico were just dark, as if they had forgotten to pay their power bill.

        Does our world really look like that all over? With brighly lit highways from one city to another and visible jet trails from space? or do we look like random luminescent features and warm spots dotted around the surface? (of course it would be hard to miss that spacejunk though, on your final approach it would
      • Canals being optical illusions, blah, blah. Yes, there was Schaperelli and his "canali", but it was Lowell who really went to town with seeing canals. Do you suppose this was the "cold fusion" of its day? Do you think it is possible, and I don't know how to put this politely, that Lowell just "blew it out his ass?"

        It would be one thing if amateur astronomers with good telescopes, good observing sights, and lots of patience saw these canals all the time. It would be like the Face on Mars -- the darned

        • But there are plenty of people since Lowell who have seen them, and people continue to till this day. Even NASA was convinced they'd see something on Mars actually causing the channels when they sent Mariner, and you can't tell me they didn't have great telescopes at the time. They were somewhat surprised when the probe got there and they couldn't see anything remotely resembling canals. However, you need not break out a telescope and point it at the red planet to see this effect. Just get a group of pe

    I suspect that all of the things other postulate about Mars are true... ie. geothermal activity, microbial life, underground water. We now just need to send people there to prove it.

    Be funny if they went there expecting life, and all they found was an old alien thermoelectric generator someone forgot to turn off before they left the planet.

  • NASA just launched 2 rovers toward Mars. I wonder whether it is too late to change the target landing zones if more evidence turns up that these are ice-producing vents. They changed Viking's landing sites after arrival, so I expect they can do the same now. Except that because of lower relative budgets, newer probes sometimes don't have some of the luxuries of earlier ones.

    Further, I have read that the landing accuracy is not sufficient enough to pick specific spots. They generally shoot for "zones", not

      Being a Mars scientist, I can help out here.

      The landing sites are not changeable at this point for a variety of reasons. First of all, they are successfully headed in the right directions now; to change the course of one significantly would be a risk that NASA is unlikely to take based on one scientist's un-peer-reviewed musings (and which may be explainable by other geologic phenomena such as relatively low albedo surfaces).

      Secondly, in addition to scientific interest, the landing sites are constrained

    Here's [nasa.gov] a photo of Mars, the elliptical bright feature at lower-center in the image is the Hellas Basin, the largest unequivocal impact basin (formed by an asteroid or comet) on the planet. Hellas is approximately 2200 km (1,370 mi) across. Really amazing detail, photo was taken by the Mars Global Surveyor, check out many more of its pics here [nasa.gov].
