SpaceX's Falcon 9 headed for ISS

On Tuesday, May 22, at 3:44 a.m. EDT (0744 GMT) SpaceX successfully launched its Falcon 9 rocket from Cape Canaveral, Florida.  This third flight of the independently designed and operated rocket system carries along with it the Dragon capsule for its second flight.  While the first two launches of the Falcon 9 and the previous launch with the Dragon were for test purposes, this flight has a different mission.  It is to be the first commercial resupply of the International Space Station (ISS).

Based out of Hawthorne, California, Space Exploration Technologies Corporation, or SpaceX, won a $278 million contract with NASA to develop their Falcon rocket systems for eventual resupply mission to ISS.  Since the retirement of NASA's Space Shuttle program, the space station has not had a single American spacecraft dock and all resupply missions have been carried out by other ISS member nations.  Currently SpaceX has a contract with NASA that runs until 2015 and includes 12 resupply visits to ISS. 

This launch is actually the second attempt for the Falcon 9 to deliver the Dragon to ISS.  The first attempt, on May 19, was canceled when an on-board computer detected an error with one of the engine's check valves.  After repairs were made to the Merlin 1C engine, the launch was rescheduled for the early morning of May 22, making for the first night launch of the Falcon 9.

The Dragon capsule (PDF) is set to deliver its payload to ISS on May 25.  While the CRS version of the Dragon that was launched is unmanned, other capsules are being built that will be capable of carrying up to nine individuals.  The CRS Dragon is composed of two storage sections.  The main pressurized section which can carry 7,300 lbs (2,210 kg) and a unpressurized section known as the trunk which can carry 7,300 lbs (3,310 kg).  The Dragon was named after the 1963 song by Peter, Paul and Mary "Puff, the Magic Dragon".

The Falcon 9, named after the Millennium Falcon from Star Wars, is a two stage, medium-lift rocket system.  It utilizes nine of SpaceX's Merlin 1C rockets to power the first stage and a tenth Merlin engine that has been modified for use in a vacuum.  The Falcon 9 is capable of carrying 23,00 lbs (10,450 kg) to low Earth orbit and 9,800 lbs (4,450 kg) to a geostationary transfer orbit (this carries payloads through a specific trajectory to safely insert it into a geostationary orbit).

  1. The Gothic

    I am the poet of the dark
    cropping in cold gardens
    dead flowers
    with pale hands

    Am I being dark
    who watches the night
    with the look of a vampire
    trying to find beauty
    that lurks in every shadow

    My eyes painted black
    see what they can not
    be seen
    by mortal eyes

    I am the night mist
    ear of
    gargoyles
    the cathedrals

    I wander in the dark skies
    where the eyes of
    crows
    shine
    the magical twilight


    in the dark
    see the light
    few still
    produces
    and on earth where beings
    day
    creep
    gently with plan
    my wings
    dark angel

    My loneliness
    devours the hours
    waiting for the day is done
    to fall on me
    cover of night
    where daydream
    without arousing

    My verses written
    with blood
    runs like a warm rain
    in abandoned buildings
    where I leave the lament of a world
    ill
    recorded


    Disease left by beings
    day
    that destroy the world
    with their impious rage
    Who are the strangers?
    Or are you crazy?


    Leave me alone with my sorrow
    because the left is crying
    After all, someone needs to cry
    then
    it's me
    being of darkness
    Nosferatu

    Let me light my fire
    in the land of the dead souls
    I lie down on the tombstones cold and pies
    left by beings
    of old

    Let me sing
    dark bowels
    Close to me
    the world is sick
    maybe there is more healing
    someone needs to cry
    then it's me
    being the dark night
