However, we still do not know about many of the functions and structural details, as it is only the water and proton exchange that has been researched in depth. Microscopic ducts convey water, electrical charges and nutrients around and in doing so, create an equilibrium within the cell. Three Nobel prizes have already been awarded for improving our understanding of these nanomembranes. Although it is thousands of times thinner than a human hair, this nanomembrane has an extremely complex structure and function. ScienceDaily (June 15, 2010) - Researchers at Vienna University of Technology (TU Vienna) are using biological principles as the inspiration to develop a new bionic fuel cell.Įvery living cell in our body can do it: covered with a thin membrane known as a cell membrane or nanomembrane, the cells can deliberately let specific substances in and out. Lou Friedman in Japan: IKAROS sail deployment proceeding IKAROS Begins Attitude Control by Louis Friedman The sail is designed to be deployed in space by centrifugal force produced by rotation of the satellite itself. A polyamide sail is wound tightly around it. Then, it will travel, relying only on the solar force, until it reaches the far side of the Sun three years after launch.Īt launch, it has a fat, short cylindrical shape. IKAROS is planned to approach Venus' orbit after a six-month flight. But, if it slows down, it will start falling downward to the Sun and approach to the orbit of Venus.
If IKAROS speeds up, with its large sail inclined toward the Sun, it will start moving away from the sun, heading outward toward the orbit of Mars. Imagine that IKAROS is orbiting the Sun at the same speed and in the same orbit as Earth. What would happen if Earth slowed down in its orbit? Earth would get closer to the Sun as the centrifugal force weakened. The Earth's orbit around the sun is constant because the centrifugal force produced by the earth's orbital motion and the force of the sun's gravity are balanced. IKAROS can both approach to and recede from the Sun with elaborate use of its solar cells and the pressure of sunlight.Įarth makes one revolution a year around the sun. The asteroid probe Hayabusa was driven by ion engines, which were energy-saving but still needed fuel called xenon gas.įlyable without fuel, IKAROS is more than energy saving – it requires no energy. Traditional satellites always needed fuels wherever their destinations were. IKAROS is a satellite to navigate space, deploying a large solar sail.

The Planetary Society has assembled a page of resources for the press on JAXA's deep-space missions, including IKAROS. This solar powered sail craft will employ both photon propulsion and thin film solar power generation during its interplanetary cruise. This spacecraft was launched together with the Akatsuki Venus Climate Orbiter aboard an H-IIA launch vehicle.
