| Posted By: Stethoscope Boy Posted On: Mar 8, 2009 Views: 1523 | Mission To Mars Just wondering what you guys thoughts are on landing humans on Mars. Do you think it's possible. And what are your thoughts on the phychological factors that the very long journey could have on the crew members. |
| Posted By: Keith Mayes Posted On: Mar 8, 2009 Views: 1522 | RE: Mission To Mars It would appear that there is no technological reason preventing a manned mission to Mars, but it would be a 30 month round trip and there would be a lot of pressure being confined in a small area with your crew mates for that long. Wouldn't fancy it myself. Plus you have to consider the radiation risk over that period. |
| Posted By: Stethoscope Boy Posted On: Mar 8, 2009 Views: 1519 | RE: Mission To Mars Yah, I've watched a few things on the mission. NASA says that they have the technology to do it, but not enough funding. The people factor, they all agree on, will be the biggest challenge. Imagine being in cramped spaces, with the same people, for 30 months. And not to mention the delay between radio signals from the craft to earth. If a problem occurs, the crew has to fix it themselves and won't be getting any instructions from earth. The best idea to make everyone phychologically OK would probably make a craft large enough to fit more people, (more than just 5-6). The more people the less phychological stress put onto the crew. Another good idea is probably building a craft that will use artifical gravity, of course, that would cost even more money. What are your thoughts on artifical gravity and space travel? I think it's a great idea for long space missions, and probably a definite direction for space travel in the future. |
| Posted By: Keith Mayes Posted On: Mar 9, 2009 Views: 1516 | RE: Mission To Mars Artificial gravity is not really an option. The craft would be too small to rotate to create centrifugal force that would be comfortable for the crew. They don´t even do it on the ISS. Plus it creates problems for antenna alignments and observations etc. No, they will just have to put up with having no gravity, and do a lot of daily exercises. |
| Posted By: Stethoscope Boy Posted On: Mar 9, 2009 Views: 1512 | RE: RE: Mission To Mars Well the craft would have to be alot larger, and it would rotate around an axis, which could hold the antennas etc. It would be an extremely expensive project though. lol its funny that you said the crew would have to live through no gravity. haha My physics teacher hates when people says there is no gravity in space, theres always gravity lol. I know you know this though, just fun. |
| Posted By: Keith Mayes Posted On: Mar 9, 2009 Views: 1509 | RE: Mission To Mars I´m not sure by what you mean when you say that there is always gravity in space? |
| Posted By: Stethoscope Boy Posted On: Mar 9, 2009 Views: 1506 | RE: Mission To Mars Newton's Universal Law of Gravitation states that any two objects exert a gravitational force of attraction on each other. The direction of the force is along the line joining the objects. The magnitude of the force is proportional to the product of the gravitational masses of the objects, and inversely proportional to the square of the distance between them. sorry for the copy and paste, just thought it was easier. Overall, no matter how far the object is from another object, there is a force of gravity acting on it. Yes it is incredibly small, but still there. Every object in the universe is applying a force of gravity on you, and you on every object in the universe. Just an very very small force. Fg = G(m1)(m2)/distance squared |
| Posted By: Keith Mayes Posted On: Mar 9, 2009 Views: 1501 | RE: RE: Mission To Mars Okay, thanks for explaining that, I wasn´t quite sure where you were coming from. Yes, gravity is everywhere, but of course is undetectable as far as our astronauts are concerned. Like you I am interested to know how the crew would cope with each other´s company for such a long period of time in such a small space. I couldn´t do it, I would go nuts. |
| Posted By: Stethoscope Boy Posted On: Mar 9, 2009 Views: 1498 | RE: Mission To Mars No Problem. Yah I have no idea how anyone could cope with the same 4 or 5 people for that long of a period of time. I doubt it's even possible, the phycholigcal stress is way to high. I can't see how they could work together to fix problems if they occur. The more i think about the more unlikely it seems possible for humans to survive through the stress. I'm leaving to Europe tommorow though (France and Italy) for two weeks. So I won't be commenting for a while. |
| Posted By: Camrin Brown Posted On: Feb 1, 2021 Views: 314 | RE: Mission To Mars We will never colonize Mars. This is a nice thought experiment and many students do research papers on essaytyper.pro on Space, I suppose, but colonizing Mars is a pipe dream at least several generations of technology away. Mars doesn't have a magnetic field like Earth, so one would have to be generated to protect the new Martian plant life and Martians from the deadly ultraviolet radiation and other cosmic rays. I say Martians because with the radiation and lower gravity, the humans who would want to try to live there would likely have to be genetically altered in order to survive. |
