“Just remember to keep it clean..”

Victoria Crater on Mars[Credit: NASA/JPL/University of Arizona.] I pointed to Earth’s old scars recently but Nasa’s Mars Reconnaissance Orbiter (MRO) HiRISE camera has taken this stunning colour enhanced image of the Victoria Crater in the Meridiani Planum region of Mars – the crater’s a mere 730m across. If you look to the left of the crater in the larger image [2Mb jpeg] you can see the tracks of Mars rover Opportunity. Earlier wondrous MRO images and video here. Meanwhile, the Cassini team in the US and in Europe are analysing the latest images from Saturn at equinox, 15 years ’til the next one. And, via the Professor, apparently the Australian Cosmos Magazine, using a Nasa radio telescope at Tidbinbilla, are to send an extensive text message to Gliese 581b, a planet in a system 20.3 light years away. Although they could have picked a better candidate at that address. ANYhoo.. they want your messages – you have until 5pm Monday 24 August 2009 Sydney time (07:00 GMT Monday 24 August 2009) to think of something appropriate. As the guys at popsci.com warn..

Just remember to keep it clean, there might be alien children reading this.

    The Rover tracks. Unbelievable. Shame Rovers didn’t work so well on Earth.

    Cheers Pete – this is a nice post.

    BTW, my efforts to capture Perseids on camera remain thwarted. Here’s to next year’s “clear skies”….

    Come and visit us at your own risk. Avoid certain areas.

    Btw, generally speaking I’ve had better views of the Geminids in December.

    There’s usually more chance of clear skies then, even if it is a bit colder.

    Apparetnly the signal most likely to reach aliens is an FM radio signal, so in years to come they’ll think that we’re all like The Archers,Chris Moyles or Terry Wogan. Oh dear
