Takao Doi, astronauta japonês, fez parte da última missão da NASA que aterrou na quarta-feira. Nesta viagem decidiu lançar um boomerang e verificar o que acontece. De facto o boomerang, na situação de microgravidade, realizou a sua trajectória como o faria na Terra, regressando ao seu lançador.
Tudo acontece porque a trajectória deste objecto não depende da gravidade, mas depende da atmosfera em si (forças e pressão exercidas na superfície deste).

Um abraço,
