Window on Mars - Can Orobes Dig Out More Info?

Misdirected Efforts

Mars is all well and good, but I really think we should be focusing on the Moon! Mars is so much farther away it takes half a year to get there. The Moon, on the other hand, only takes two days. And if anything goes wrong, the Moon is actually close enough we might be able to get there in time to do something about it.

I don't see a problem with sending "orobes" to Mars, because it's always good to know something just for the sake of knowing, but knowledge of the Moon is much more practical. We've had the technology for decades to establish a Lunar colony . Why didn't we? There's water, and therefore oxygen, and most of the metals you could possibly desire all on the Moon. We should establish a Lunar colony first, and then worry about manned missions to Mars.

A space elevator wouldn't hurt either.

One thing that I love about this whole thing is that the missions seem to complement each other. Interesting is also that they will be able to use each others orbiting crafts as relay stations.

I have seen what the trajectory for a mission to mars would be like - It makes no difference that mars is closer to earth, because the spacecraft cannot fly in a straight line between the two worlds unless we managed to develop a far more powerful propulsion system. You have to fly in a spiral trajectory around the sun that would only intercept mars after a year, and spend a year or so on the planet to wait for earth to be in the right position for the return flight. You would then leave mars to orbit around the sun, firing thrusters in reverse to spiral in an intercept the earth after another year or so. The total mission time would run from 3 to 5 years.

That is why going to mars is so much harder than going to the moon. The astronauts have to be kept alive and sane for years, not weeks as was the case with Apollo.
