<p>The Korean Aerospace Research Institute (<a href="https://www.kari.re.kr/eng.do" target="_blank" rel="noopener noreferrer">KARI</a>) announced that its solar-powered drone has successfully completed its longest flight in Korea.</p>
<p>The agency said that its solar-powered electrical aerial vehicle (EAV-3) succeeded in flying for 53 hours at a high altitude where the air was insufficient. It soared to a height of 12-18 kilometers in the stratosphere for 16 hours. Previously in 2016, the solar-powered drone completed a 90-minute flight at an altitude of 18 kilometers.</p>
<p>In its press statement, the research institution said that it would utilize a high-performance battery pack and the solar cell to enhance the performance of EAV-3. It added that EAV-3 could stay for several days or even months at a high altitude of 12 kilometers in the stratosphere to execute different activities such as communication relay, real-time image transmission, procurement of ground observation, and atmospheric data. It could also surveil natural disasters and real-time illegal fishing.</p>
<p>It also has plans to collaborate with Korean industries to speed up developing the Korean model of high-performance batteries for high altitude. It is also working to develop a high-performance battery pack and lightweight structure technologies. The communication performance of the technology is enhanced to receive real-time high definition images from distances of up to 50 kilometers.</p>
<p>According to the press note, Zephyr from Airbus DS holds the world’s longest flight record for solar-powered unmanned aerial vehicles, which flew for 26 days in 2018. U.S.-based Amprius’s high-performance battery helped to achieve the record.</p>
<p>Solar is making news in other transportation based applications.</p>
<p>In August 2020, SolarStratos, a Switzerland-based technology firm, <a href="https://mercomindia.com/first-skydive-solar-plane/" target="_blank" rel="noopener noreferrer">announced</a> that its founder Raphael Domjan had completed the first-ever skydive from a solar-powered plane over Payerne, Switzerland. Domjan jumped from the two-seater plane after it soared to an altitude of 1,520 meters (5,000 feet). The parachutist reached a speed of over 150 kilometers/hour during his fall</p>
<p>Mercom earlier <a href="https://mercomindia.com/nasa-solar-generator-international-space-2020/" target="_blank" rel="noopener noreferrer">reported</a> that Israel’s leading research university, Ben-Gurion University, had designed a miniaturized solar-power prototype that would help private commercial space missions.</p>
