    First pictures from New Horizons.

    New Horizons: Pluto map shows 'whale' of a feature.



    The US space agency's (Nasa) New Horizons probe is now less than seven days away from its historic flyby of Pluto.

    New Horizons is moving at nearly 14km/s - far too fast to go into orbit on 14 July. Instead, it must gather as much information as it can while it sweeps past not just Pluto, but its five moons as well: Charon, Nix, Kerberos and Hydra.

    The BBC will be screening a special Sky At Night programme called "Pluto Revealed" on Monday 20 July, which will recap all the big moments from the New Horizons flyby.

    HERE is the link to the full report.




    At it's closest, Pluto, ( which has been downgraded to a dwarf planet ), is 7.5 Billion kilometres from Earth, but as its orbit is extremely tilted in regards to the other planets,this orbit sometimes brings it closer to the sun than Neptune is.

    I think that this will be a very interesting programme to watch.

    Don't you ?

    I like easy to understand space science too and it will be interesting to see exactly what Pluto looks like.

    Shame they could not put the New Horizons craft into orbit around pluto though.

    I suppose the incredible distances any signal would have to travel would make that impossible.

    Yes Zath', as light, ( and radio signals ), take 4.6 hours to reach Pluto and another 4.6 hours to come back, the total round trip distance in time - at the speed of light - is around 9.2 hours. Too long for any working instructions to be sent to and received back from the New Horizons spacecraft.

    Still a great feat of engineering which will, I hope, tell us a lot of "stuff" about the tiny planet Pluto.

    Cannot wait for the TV programme on the twentieth.

    God, it was !

    And since the original programme we have seen better and better pictures coming from the craft as it gets closer and close to Pluto and it's moons.

    It is quite astounding that such a tiny target so far away from earth could be approached accurately enough to send back such beautiful pictures.

    It's a bit like trying to hit a beach ball with a pea-shooter from a hundred miles away

    What an achievement for modern astronomy and for the astronomical sciences.

    More pictures to come. Watch this space. ( Sorry for the pun ).Very Happy
