Every time I see space clips all I can think of is the moon landing. Some day they must come clean! Why would they plan a 2030 landing on the moon if they did several safe ones in the late 60s and in the 70s. A gap of 60 years? Why no extended interviews? One press conference and thats it? No high jumps on the surface? So many questions.

Keke2000 maybe they are planning something in 2030 if a http://www.snotr.com/video/10052#comment-190872man can do this then im pretty sure man can reach the fecking moon

i mean if a man can do http://www.snotr.com/video/10052#comment-190872 then a huuman can reach the moon
ie reach that height in a helium-filled balloon then im pretty sure they can reach the moon etc before any1 mis reads my comment

I think Mars is not an option for future human colonisation. Any base we might establish there would be very difficult to sustain.
Maybe a better option would be to find a way to terraform Venus, which has a denser atmosphere than Mars and Earth - a toxic atmosphere, but an atmosphere nevertheless. This might be achievable over centuries if we could find a way of sending genetically modified organisms into the Venusian atmosphere to convert the carbon dioxide there to oxygen and carbon. We already have some organisms on Earth that can survive at very high temperatures and pressures, so those could be candidates for some DNA insertions to effect the necessary functions.
With the right mixture of organisms we might be able to transform the entire planet into somewhere survivable. Venus is much closer to Earth in terms of size, and therefore surface gravity, than Mars. Our chances of finding, let alone reaching, a planet that is more suitable for Earth-based life forms anytime soon are close to zero so it's got to be worth a shot. At some stage we are going to have to start journeying to other planets to escape our dying star, so Venus would be a good candidate for us to learn some terraforming skills.

#6 venus is 462 °C, thats a bit warm for my taste!

I'm well aware of that #7. Clouds of sulphuric acid, extreme atmospheric pressure: it's not a welcoming environment.
But it still has more potential than Mars as a possible place to live. There are creatures on Earth that can survive the kind of extreme conditions seen on Venus. We have bacteria and even some multicellular creatures whose chemistry runs on sulphur and appear not to require oxygen. They can be found around deep sea volcanic vents, operating at temperatures and pressures that would kill most other creatures.
I reckon we have, or will soon have, the technology to genetically modify some of those to not only survive in Venus, but to use them to transform the Venusian atmosphere into something resembling Earth's. The atmosphere is the key to making the planet habitable: if we can reduce the greenhouse effect and manufacture oxygen then we can eventually introduce other, similarly genetically-modified, organisms to further prepare the planet for life.
It's not going to be easy, and it's not going to be quick but I think it's our best way forward if we want to leave this planet and ensure our long term survival.

lets face it earth is the only place we can live
so we have reached the moon yes granted but still not possible to breath with out oxy tanks and suits
we are on this planet for a reason another thing i can say is niether of us will be alive the day when it comes people can live on diff plannet *8* satre i see your points and found them very interesting
•Why does NASA believe there might be life on Mars? The CD player was stolen from their Mars rover
