    [00:01.50]So what is the future

    [00:03.66]of the exploration of Mars?

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

    [00:09.71]which means that a space probe

    [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]
