The electric solar wind sail is a propulsion system that extracts the solar wind momentum for the thrust force of a spacecraft by using an interaction between solar wind protons and the electric potential structure around charged long thin conducting tethers. The system enables a spacecraft to ...
descriptive and analytical comparison of various methods. The selection of the appropriate treatment method depends largely on the nature of the pesticide and the effectiveness of the chosen technique. In many cases, technologies such as membrane bioreactors and the fenton process could be integrated wi...
Samsung and the NPA signed an agreement on Wednesday in which the technology powerhouse will develop an artificial intelligence (AI)-based system to identify and protect against voice phishing schemes; and the NPA will offer a trove of related data collected and analyzed using the hundreds ...
A solar power sail can be a hybrid propulsion system with a solar sail by activating the ultra-high specific impulse ion engines with the power generated by thin film solar cells. This paper also introduces an advanced solar power sail mission toward Jupiter and Trojan asteroids via hybrid ...
Solar SailAdvanced Reflectivity Control DeviceThe authors are currently developing a novel attitude control device for solar sails. The device is called Advanced Reflectivity-Control-Device (A-RCD) which can change the optical properties between diffuse reflection and oblique-reflection. This device is ...
