Os astronautas da missão Artemis II, passam por uma interferência na comunicação, prevista para durar cerca de 6 minutos, durante retorno à Terra nesta sexta-feira (10). O "blackout" ocorre devido ao intenso aquecimento que a cápsula é submetida após reentrada na atmosfera terrestre, formando um plasma ao redor da nave e impedindo a passagem das ondas de rádio.

O iG acompanha a transmissão da NASA. Confira:

Mais cedo, também como parte do processo de retorno à Terra, a cápsula Orion se desprendeu do módulo de serviço e houve a última "queima" dos motores para ajuste de trajetória.

Segundo a NASA, a perda de comunicação é um procedimento planejado, normal e esperado, com o sinal sendo reestabelecido assim que a nave atravesse a parte mais crítica à aproximadamente 38.000 km/h.

O pouso está previsto para às 21h 07 min, no Oceano Pacífico, na costa de San Diego, Estados Unidos. Logo depois, os tripulantes serão resgatados pela equipe da NASA.

Missão histórica

Lançada em 1º de abril a partir de Cabo Canaveral com o foguete Space Launch System, a missão retorna à Terra depois de contornar o lado oculto da Lua.

Os astronautas Reid Wiseman, Victor Glover, Christina Koch e Jeremy Hansen alcançaram a maior distância da Terra já registrada por humanos.Eles fizeram parte do primeiro voo tripulado nas proximidades da Lua desde o programa Apollo, encerrado na década de 1970.

A missão também marcou avanços simbólicos: Glover é o primeiro astronauta negro em uma missão lunar; Koch foi a primeira mulher e Hansen, o primeiro não norte-americano a participar de uma operação desse tipo.
