[00:01.50]So what is the future

[00:03.66]of the exploration of Mars 1?

[00:06.13]In 2014, the first return flight is planned,

[00:09.71]which means that a space probe 2

[00:11.37]will bring back to Earth samples of Martian

[00:13.86]rock and soil.After that,

[00:16.01]there might be the first crewed flight to Mars.

[00:18.99]At the moment, a manned mission to Mars

[00:20.90]is right at the edge

[00:22.20]of our exploration abilities.

[00:24.19]There are many problems because of the length

[00:26.58]of the return journey

[00:28.02]which would take about two years.

[00:30.01]But a manned flight could explore the planet

[00:32.25]further and even analyse the possibilities

[00:35.15]for human settlement on the planet.

[00:37.42]Who knows? Maybe our grandchildren

[00:39.80]will be living happily on the Red Planet.

[00:42.56]To sum up,in many ways Mars is our new frontier

[00:46.73]Now that we have explored our own planet,

[00:49.19]this beautiful, mysterious, red planet

[00:51.89]remains open to us.

[00:53.61]Let's just hope that we don't make such a mess

[00:56.25]of it as we have done of Planet Earth.

[00:58.44]That's all,thank you.

[00:59.39]
