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:
“I call to mind the navy great
That the Greeks brought to Troye town,
And how the boistous winds did beat
Their ships, and rent their sails adown;
Till Agamemnon’s daughter’s blood
Appeased the gods that them withstood.”
—Henry Howard, Earl Of Surrey (1517?–1547)
“Pour down your warmth, great sun!
While we bask, we two together.
Two together!
Winds blow south, or winds blow north,
Day come white, or night come black,
Home, or rivers and mountains from home,
Singing all time, minding no time,
While we two keep together.”
—Walt Whitman (1819–1892)
“The seeds of the life of fishes are everywhere disseminated, whether the winds waft them, or the waters float them, or the deep earth holds them; wherever a pond is dug, straightway it is stocked with this vivacious race. They have a lease of nature, and it is not yet out.”
—Henry David Thoreau (1817–1862)
