인공위성의 대안, 태양열 풍선 VIDEO: Balloons that float on the edge of space equipped with sensors that mean

Balloons that float on the edge of space equipped with sensors that mean they NEVER move from one spot could become cheap alternatives to satellites, says the US military

 

The solar-powered balloons are able to do this thanks to new sensors

Winds can be predicted meaning the balloon can make adjustments in time

US military believes balloons could be alternatives to satellite communications

인공위성의 대안, 태양열 풍선   센서가 장착된 우주 가장자리에 떠 있는 풍선은 결코 한 곳에서 움직이지 않는다는 것을 의미한다고 미군은 말한다. 미군은 정확히 같은 지점에서 성층권에 떠다니는 태양열 풍선 제작을 계획했다. 풍선 실험을 시작한 미국방위고등연구계획국(DARPA)은 풍선들을 인공위성의 값싼 대안으로 사용할 수 있을 것으로 기대하고 있다. 애플리케이션에는 다른 국가의 감시는 물론 원격 지역 또는 재해 지역과의 통신이 포함될 수 있다. 황기철 콘페이퍼 에디터 큐레이터 Ki Cheol Hwang, conpaper editor, curator

The US military is set to create balloons that could float in the stratosphere in exactly the same spot indefinitely.

The Defense Advanced Research Projects Agency (DARPA) - which has started testing the balloons - believes they could be used as cheap alternatives to satellites.

Applications could include communications with remote areas or disaster zones, as well as surveillance of other nations. 

         Just earlier this year, Alphabet launched six communication balloons (pictured) as part of a landmark test. 

         They travelled 12 miles (20km) above the Earth's surface and harnessed power from card table-sized solar 

          panels that dangle below them 

The solar-powered craft are able to anchor themselves in place thanks to sensors that can predict changes in the direction of the wind and an on-board motor compensates for the movement.

Military aircraft fly at a maximum of 65,000 feet (20,000m) while these balloons operate at up to 90,000 feet (27,000m) and would therefore be virtually impossible to intercept.
