Phoenix Digs First Mars Soil Sample To Analyze

Posted by CmdrTaco on from the sing-the-peter-gabriel-song dept.

An anonymous reader writes "Nearly two weeks after its historic landing, the US Mars probe Phoenix has scooped up its first sample of Martian soil and begun analyzing it for water and organic compounds. The test dig made Sunday by the Phoenix Mars Lander's 8-foot-long robotic arm uncovered bits of bright specks in the soil believed to be ice or salt. Mission controllers will send instructions to the lander to dump the sample into one of the Thermal and Evolved-Gas Analyzer (TEGA) ovens. The TEGA ovens, which are about an inch long and the diameter of a pencil lead, will heat up the soil samples and use a mass spectrometer to detect the gases that come off the samples, which will shed light on some of the materials in the soil, specifically those formed by the process of liquid water."

      What's the big deal? Our space program doesn't really get much in terms of funding, especially compared to other Government programs. There's a lot of pork to cut from our budget, and if politicians start focusing on something that's a small part of a federal budget then I think they should first focus on the big blunders that got some of them rich (like the "Bridge to Nowhere").

      In any case, Politicians should not be dictating what we peruse with science. They are not qualified and would let personal beliefs and "the bottom line" cloud their judgement.

      As far as Science is concerned, learning that something is not there is just as important as learning as something is there. We learn something, maybe it has little value or maybe a lot. But we learn something that may be important down the line.

      Not everything has to be quantified in terms of "what do we get out of it." And nothing should be quantified in terms of "what do we (the politicians) get out of it."

The average person also doesn't understand the benefits that we get from the space program. They are not aware of the important role that space exploration plays in our everyday lives.

      Erm... No.

      We have no experience of long-duration space flight outside Earth's magnetic field. The longest (and only) manned flights outside it have been to the Moon and lasted only a couple days. We are talking about multi-year flight with little protection from cosmic radiation. We need to properly shield the spaceship or they will be cooked before they get there.

      Even if we ignored that, we still need to build a spaceship that can carry astronauts to Mars and back, and that is not a trivial task. It has to be big enough to carry crew, supplies and spare parts for the redundant system. We are talking about something the size of the IIS, with a big engine attached to it. Even if we don't use solar panels and go nuclear (in violation of several annoying treaties), the spaceship required would be quite big.

      There is also the question of the Mars landing. We have never landed anything there that's bigger than my desk. We are talking about a powered landing of several habitats, supply-storage facilities and fuel manufacturing facilities and the solar or nuclear power required to power them.

      After the landing, we will also have to shield astronauts from cosmic radiation, since Mars have no magnetic field to speak of. They will have to be protected on the ground for the duration of the stay.

      As for coming back, we will have to conduct a launch of a reusable, probably single-stage-to-orbit (as we want to cut down complexity as much as we can), vehicle. We never did that, but Mars has a more forgiving gravity than the Earth and we may already have the proper technology for that.

      After that, the vehicle I just described must dock with the return vehicle (which may of may not be the same vehicle they arrived in) to return to Earth. They may carry additional Mars-made fuel in the lift-off vehicle if the weight budget allows and maybe use its engine to assist the return craft own engines.

      As much as I would like to see it done next year, I know there is a lot of homework to be done before we can take someone to Mars and back.

      It's hugely complicated.

      Let's get back to the Moon first, make sure we have the technology to survive there for long periods and then venture on to Mars. A dozen dead astronauts won't help.

      I think it's much, much harder. In the 60s we had, basically, to build reliable rockets and spacecrafts for a week-long trip. In order to go to Mars, we need to build spaceships that go farther, faster and last longer. A LEM would not be able to get back to space if it stayed on the Moon for more than a month. We have never landed anything bigger than my desk in anything remotely like Mars. Those are really messy problems.

      Going to the moon was extremely difficult too. Remember, before the creation of NASA, the US had never launched anything into space, nor had we ever attempted to attain escape velocity. To go from zero, as it were, to craft capable of taking humans safely to orbital, and then escape velocity was a huge achievement.

      By comparison, much of the prototype work for the Mars trip has already been done. We already know how to get to escape velocity, we've worked out the orbital mechanics, and we even know the basics of landing. Hell, the Viking landers figured all that out in the '70s. The big obstacle now is to make a life-support system capable of sustaining human life for the three month voyage. True, its no easy task, but I don't think it's more difficult than building a space program from scratch.

We are talking about multi-year flight with little protection from cosmic radiation. We need to properly shield the spaceship or they will be cooked before they get there.

      That's a fair point, and one that I don't think that people emphasize enough. The difficulty of designing a life-support system for long term spaceflight is not to be underestimated.

      It has to be big enough to carry crew, supplies and spare parts for the redundant system. We are talking about something the size of the IIS, with a big engine attached to it. Even if we don't use solar panels and go nuclear (in violation of several annoying treaties), the spaceship required would be quite big.

      Why would the spaceship require an especially large engine? In space you don't have nearly the same amount of friction and drag that you do on Earth. Even relatively small rockets can be effective once you're outside the atmosphere.

      There is also the question of the Mars landing. We have never landed anything there that's bigger than my desk. We are talking about a powered landing of several habitats, supply-storage facilities and fuel manufacturing facilities and the solar or nuclear power required to power them.

      Who says we have to deliver it all in one giant load? It'd be much more effective to launch all of the supplies ahead of the astronauts and make sure that everything had landed properly before sending humans on their way.

      As for coming back, we will have to conduct a launch of a reusable, probably single-stage-to-orbit (as we want to cut down complexity as much as we can), vehicle. We never did that, but Mars has a more forgiving gravity than the Earth and we may already have the proper technology for that.

      Why does the orbiter have to be "reusable"? I mean, look at the Apollo missions - the lunar lander had a single-use return to Earth module. Shouldn't we use a beefed up variant of that design?

      After that, the vehicle I just described must dock with the return vehicle (which may of may not be the same vehicle they arrived in) to return to Earth.

      Assuming that you've got the life support requirements worked out (which you've had to do in order to make the trip out to Mars), this procedure is virtually identical to the procedure that the Apollo astronauts had to do in order to return to Earth. The LEM had to dock with the command module for the return trip. This is the same thing, only you're docking with something like the ISS, rather than the Apollo command module.

      It's hugely complicated.

      That it is, but you're forgetting that a lot of it has already been done

      Let's get back to the Moon first, make sure we have the technology to survive there for long periods and then venture on to Mars. A dozen dead astronauts won't help.

      How will living on the moon help us with going to Mars, pray tell? The moon is still inside the Earth's magnetic field, so it won't help us with the most pressing issue - designing a craft to carry humans through interplanetary space. And, as for the other problems, they were already all solved during the '60s. Why do we need to solve them again?

      Actually, half the spacecraft we sent to mars become craters -- not an acceptable risk level for a human mission. Also we've never sent anything to mars which returned to earth. Taking off again from a gravity well makes it twice as difficult as a one way trip. Plus there's the fact that a year of living supplies makes for a very large spacecraft, which then needs much more propellant too.
