Its precise, pulsed laser technology ridges you of small satellite debris ranging from 1 to 10 centimeters.
6
Just point the broom's beam at it to vaporize parts of the junk.

This gives it a directional thrust, lowering its orbit until it burns up in the atmosphere.
8
Need more force for bigger chunks?

Try the space harpoon.

O que é a Técnica de Shadowing?
Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
