Its launch was made on May 20, 2010 by the launcher H- II He also responsible for placing the Venusian probe Akatsuki ( Planet-C ). The solar sail uses the solar radiation pressure to speed up. When this technology is mastered it will be able to allow reduced mass spatial probes to move into the solar system.   Ikaros’ mission has an initial duration of 6 months. Jaxa Study development following this mission and during the decade 2010 of a space probe equipped with hybrid propulsion and including a solar sail for the exploration of Trojan asteroids. Ikaros P\u00e8se 315 kg including 15 kg For sail. The square sail of 14.1 meters with side (20 meters diagonal) is made of polyimide of 7.5 \u03bcm thick. Solar cells cover 10% of its area. Sailing portions are able to generate a variable thrust. In the center of the sail is a capsule one meter in diameter which contains all the other components of the satellite [ first ] .        (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4The sail of Ikaros is, at launch, wound around the central, massive part of the satellite, containing in particular control electronics and small orientation control engines. Once in orbit, the satellite is rotated (36 laps per minute) by its engines which leads to the deployment of sail. It remains nevertheless partly ferry . The whole then takes the form of a four -branched seasick whose ends are equipped with small masses of 0.5 kg which contribute to the deployment of the branches of the star. When this first phase is completed, the system now the closed sail is released, which allows the complete deployment of it. Finally the speed of rotation is reduced by the orientation engines. To orient the sail, eight parts of it located near each angle more or less reflect the photons when you pass an electric current. By electrifying two bands differently located on both sides of the satellite mass center, there is a couple of forces that can be pivoted the sail on demand [ 2 ] . Two objectives are assigned to him, namely: Validate the solar sail deployment system and the ability to capture solar energy thanks to the cells installed in sailing; Demonstrate the capacity of the satellite to move and make navigation. Ikaros is put in orbit the May 20, 2010 by the Japanese rocket H- II He also responsible for also placing the Venusian probe Akatsuki in orbit ( Planet-C ).The deployment of solar sail, a particularly delicate phase of the mission, is carried out the June 10, 2010 [ 3 ] . The July 16, 2010 , Ikaros begins to advance thanks to the solar radiation pressure [ 4 ] . The Gap Polarimeimeter ( GAmma-ray burst Polarimeter ) detected a gamma start [ 5 ] .  The mission made it possible to verify the performance of a propulsion based on a solar sail. The total thrust exerted by photons on solar sail with an area of \u200b\u200b173 m 2 was measured at 1.12 milliNewton (that is to say 0.114 grams on earth) Value very close to what was provided by the designers of the spatial probe [ 6 ] . The force exerted on the spatial probe of a mass of 315 kg Increases the speed of ten m\/s after a month. Based on a six -month program, the first mission was theoretically completed and successfully fulfilled in 2010. However, Ikaros has since continued its flight: in 2015, it still has orbit around the sun in ten months. Its electrical capacity being low, it is in hibernation mode for seven months, at the end of which it is awakened by the technicians of Jaxa which collect the probe data for three months. His fourth awakening took place in mars 2015 [ 7 ] .
