Sonda Psyche da NASA recebe impulso gravitacional de Marte

A sonda Psyche da NASA sobrevoou Marte em 15 de maio, utilizando a gravidade do planeta para ganhar velocidade e ajustar sua rota. A manobra a aproximou mais de Marte do que qualquer uma das luas do planeta.

A sonda passou a 4.506 quilômetros de Marte a uma velocidade de 19.795 km/h durante sua máxima aproximação por volta das 15h30, horário do leste dos Estados Unidos. Essa distância foi menor do que a órbita de Fobos, que gira ao redor de Marte a uma distância de 5.955 quilômetros. O sobrevoo foi um impulso gravitacional planejado, projetado para conservar o gás xenônio utilizado pelo sistema de propulsão iônica solar-elétrica.
