Incredible slo-mo footage captures the moment a bullet EXPLODES into a 'sideways mushroom cloud' in high speed test on spacecraft shields

ESA is working to develop shielding to protect craft from debris of varying sizes

In the experiments, they used a gas gun to test thin layers of bonded metal

The bullet burst after hitting shield, making it easier for other layers to catch

강력한 우주선 보호재 개발 총알 시험 

유럽우주기구(ESA)는 우주선의 여러 크기의 외부 파편에 견디기 

위한 보호재를 개발하기 위한 연구를 하고 있다

이번 시험에서는 얇은 다중 철판를 시험하기 위해 가스총과 

초속 7km 속도로 발사되는 2.8mm 알루미늄 총알을 사용했으며

총알은 시험대상인 철판을 뚫고 나간 후에 마치 버섯 구름처럼 

파열되는 모습을 보여준다.

우주선에 사용되는 보호재는 10~30cm까지 두께의 다중층으로 만들어진다.

High-speed footage from ESA’s latest tests to create ultra-durable spacecraft shielding reveals the incredible moment a bullet travelling 4 miles per second bursts into a ‘cloud of fragments and vapor’ after piercing one of the candidate materials.

The space agency is working to develop shielding made from thin layers of metal that can protect its craft from cosmic debris.

In orbit, spacecraft are at risk of collisions with everything from tiny objects smaller than 1 centimeter to meteoroids from seasonal streams – and, the experts are working to ensure they’re equipped for whatever comes their way.
