US & Russia Pencil in Mars Launch by 2018

snilloc writes "The Washington Times is reporting that the US and Russia (and the Europeans are mentioned too) are planning for an eventual manned Mars trip. Suggested launch years are 2014 or 2018. The article discusses unmanned probes at greater length than the manned plans, but check out the Russian isolation experiment where 6 people will spend 500 days in a simulated spacecraft environment. (Sounds like a good reality TV show to me.)"

The simple fact is that we're probably not going to get to Mars in the next 20 years, it simply isn't as simple as people would like to think. Most of the problems revolve around the fact that any expedition to mars would last up to 3 years(apollo 11 took around a week) and for the great majority of this the team would have to cope with problems unaided. Consider this: The CLOSEST that mars gets to earth is 86.5 million KM which means that any communication with the earth is going to take 5 minutes to get there and the response 5 minutes to get back. That means that for any problem that can't be solved in 10 minutes you're completely on your own. The astronauts on Apollo 13 would have been doomed had they had a 10 minute communication lag with ground control. other problems include sickness (its going to happen if you're away for months and illness that are trivial to cure on earth would be major problems halfway to mars, not to mention the degeneration of muscles, bones and the heart caused by being weightless for long periods of time), nutrition(how do we keep our astronauts in tip top shape for months on end when we have no way of getting food to them), radiation and pyschological problems (think being couped up in a space the size of your living room with 5 people for a couple of years). Yes, most of these problems are solvable (especially if we develop a technology considerably faster than chemically fuelled rockets) but the fact is almost everything that a manned mission would achieve can be done for less money and risk by robots. Its just not going to happen.
