Any time an astronaut gets out of a spacecraft (航天器) while in space, it is called a spacewalk. Astronauts go on spacewalks for many reasons. For example, experiments can be placed on the outside of a spacecraft. This lets scientists learn how being in space affects (影响) different...
(航天器) while in space, it is called a spacewalk. Astronauts go on spacewalks for many reasons. For example, experiments can be placed on the outside of a spacecraft. This lets scientists learn how being in space affects( 影响) different things. By going on spacewalks, astronauts can ...
This first paper is thus a general introduction to the nature of spacecraft engineering and its application to robotic spacecraft. I consider the constraints and metrics used by spacecraft engineers in the design of spacecraft and how these constraints impose challenges to the roboticist. The ...
根据上文“Astronauts also need to wear a SAFER to stay safe during spacewalks."和下文“It helps an astronaut move around in space."可知, 此处应与 SAFER有关,选项A“SAFER像背 包一样背着”符合语境。 故选A 19. 根据上文“Another way astronauts practice spacewalks is by using virtual real...
根据第一段中What's a spacewalk?Any time an astronaut gets out of a spacecraft while in space,it is called a spacewalk.可知什么是太空行走?当宇航员在太空中走出飞船时,这被称为太空行走。结合文章主要介绍了太空行走。解释了进行太空行走的原因,太空行走的流程和宇航员如何进行太空行走训练的。最后提到了...

An eclipse is an incredible thing to see from Earth, but it's even more epic from space. A new video taken by the European Space Agency's Proba-2 spacecraft on Feb. 26 shows a solar eclipse through the mechanical eyes of the probe, tasked with staring at the sun day in and day ...
根据后一句“Tethers are like ropes, andconnect the spacewalkers with the spacecraft."可知,tethers是像绳子一样的东西,再结合选项提示可推断tether意为“系绳”。故选B。3.B细节理解题。根据第三段中的“Another wayastronauts practice for a spacewalk is by using virtualreality.”可知,进行太空漫步训练的...
When on a spacewalk,astronauts use safety tethers to stay close to theirspacecraft. Tethers are like ropes, connect thespacewalkers with the spacecraft. They keepastronauts from floating(漂浮) away into space.Another way astronauts stay safe during spacewalksisby wearing a SAFER. SAFER is worn ...
