Jacob Bloomberg helps astronauts get their balance back

EarthSky

Today, we're speaking with Jacob Bloomberg, senior research scientist at NASA Johnson Space Center. He said that astronauts returning from the zero gravity of space often have trouble with balance.

今天节目的嘉宾是来自美国宇航局约翰逊航天中心的高级研究员、科学家雅各布·布隆伯格。他告诉我们,宇航员适应了太空的微重力环境,回到地球后平衡感会出现问题。

Jacob Bloomberg: Crew members may have difficulty turning corners, walking straight lines, things that are fairly easy for us to do here on Earth but are difficult during this period of adaptive change.

雅各布·布隆伯格:人们在地面上很容易做到的事情,如转弯、直走这类基本动作,对宇航员来说都很困难,因为他们要经历一段适应期。

Bloomberg said it can take up to 4 weeks for astronauts to adapt to Earth's gravity after long space missions. He's working with the National Space Biomedical Research Institute to create a training system to speed up that transition. Astronauts walk on a treadmill with a moving base, while watching a projected image that's also moving.

布隆伯格称,宇航员执行完一项长期的太空任务后,通常需要4周时间来适应地球上的重力环境。目前他正与国家太空生物医学研究所合作,共同研制一套训练方案来缩短适应期。受训练的宇航员将在跑步机上一边行走,一边观看研究人员准备的动态图像。

Jacob Bloomberg: The training system hinges on this concept of learning to learn. What idea is you can train the brain to become more adaptable if you're exposed to training that pushes the system in an adaptive way.

雅各布·布隆伯格:这套方案建立在“学会学习”的理念基础上。其原理是,当人们处在富有挑战性的环境当中,大脑的适应能力就会变强。

In other words, when an astronaut's brain has already been challenged to deal with sensory conflicts, it's more prepared to deal with the transition back to Earth's gravity. Bloomberg said his system could also help people on earth improve their balance.

也就是说,当宇航员的大脑受到挑战,能处理感官上的矛盾,他们也就能更好地适应地球上的重力环境。布隆伯格表示,这套方案还可以帮助人们改善平衡能力。

Our thanks today to the National Space Biomedical Research Institute – innovations for health in space and on Earth.
