Space travel to Mars is still too dangerous. Science, especially applied science is not sufficiently developed to make a space craft safe enough for a Mars expedition. One of the problems of launching a Mars expedition is the horrendous cost. It will cost billions of American dollars. It will also consume a lot of brain talent, talent that could be used elsewhere. Even today (2007), it is difficult to successfully land a probe to Mars. The distance makes is difficult, so does the gravitational pull verses lack of atmosphere resistance. There is a very good reason why humans have not even attempted to landfall Mars.

Cosmic and Solar radiation
The question of solar and cosmic radiation is still an embryonic science. Even our scientific knowledge of radiations on our flight attendants and pilots has not been thoroughly researched. Some scientists believe the risk of exposure to radiation is much greater for these professionals than the land bound ones.

The spaceships and spaces suits do offer protection against a gamete of radiation. It would be essential that important to measure the types of radiations and their intensities in the cosmos. Of course there will be fluctuations and hot-spots. It will be also important to measure the external and spaceship and spacesuit leaks. In science, one cannot really on theory and assumptions. Hard scientific data has to be done before humans are launched to Mars.

Atmosphere on Mars
We no the atmosphere on Mars is moon like, that is to say thin. This lack of atmosphere provides little shelter against cosmic radiation. It also means Mars explorers will always have to wear space suits when out of their space ship or on ground shelters. They will also have to wear their space suits against the unbridled heat of the sun and against the untempered cold of the night. They will need to bring a lot of oxygen or a way to generate oxygen. The lack of atmosphere means little resistance and a hard landing for space landers.

Isolation Factor
The threat of isolation is one of the greatest threats against would be space explorers. For the most part, going to Mars means a lot of time away from family and friends. The trip may even be one way. It means goodbye to Starbucks, mangoes, skiing, the beaches, and the sunsets of the earth. It means no pets, no baking, no favorite hair salon. Even the humans you bring are all too much like yourself, focused, professional, and not necessarily friends.

One way trip
Landing on Mars is a real big challenge. Landing is such a big challenge that some Mars projects forgo that part to concentrate on the orbit the Mars study approach. It is that much easier. Launching from Mars could even be more difficult. Currently, the science is not developed enough to guarantee a return to earth. On additional to all other rigorous requirements, the scientists have to face the possibility of never coming back. Even the ones who are in the orbit only explorations. Even if they are able to approach the earth again, the space around earth will be so cluttered with space debris that is will be really hazardous to make a re-entry.

Space travel to Mars is too dangerous currently. Return to earth will become more and more hazardous as we put more scientific and communication instruments up in orbit around the earth.
