WINDS

WINDS (Wideband InterNetworking engineering test and Demonstration Satellite, also known as Kizuna), is a Japanese communication satellite. Launch was originally scheduled for 2007. The launch date was eventually set for 15 February 2008, however a problem detected in a second stage manoeuvring thruster delayed it to 23 February. Lift-off occurred at 08:55 GMT on 23 February, and the satellite separated from the carrier rocket, into a Geosynchronous transfer orbit at 09:23, launched by an H-IIA carrier rocket from the Tanegashima Space Center. It will be used to relay the internet to Japanese homes and businesses, through Ka-Band signals. It will also develop technologies to be utilised by future Japanese communication spacecraft. It is part of Japan's i-Space program, and is to be operated by JAXA and NICT.

JAXA claim that WINDS will be able to provide 155 Mbit/s download speed to home users with 45-centimetre diameter satellite dishes, whilst providing industrial users, via 5-metre diameter dishes, with 1.2 Gbit/s speeds.

WINDS has a launch mass of 4,850 kg, reducing to around 2,750 kg when in orbit. The spacecraft is 8 m x 3 m x 2 m in size, and its solar panels have a span of 21.5 metres. It has three-axis stabilisation, and a design life expectancy of five years.

Famous quotes containing the word winds:

    Since I was not bewitched in adolescence
    And brought to love,
    I will attend to the trees and their gracious silence,
    To winds that move.
    Philip Larkin (1922–1986)

    The winds awaken, the leaves whirl round,
    Our cheeks are pale, our hair is unbound,
    Our breasts are heaving, our eyes are agleam,
    Our arms are waving, our lips are apart....
    William Butler Yeats (1865–1939)

    But the best I’ve known
    Stays here, and changes, breaks, grows old, is blown
    About the winds of the world, and fades from brains
    Of living men, and dies.
    Rupert Brooke (1887–1915)
