STEM的雾趣

On March 30, 2023, NASA astronauts Kjell Lindgren, Jessica Watkins, and Robert Hines took part in STEM demonstrations with local students in Washington. Lindgren, Hines, and Watkins spent 170 days in space as part of Expeditions 67 and 68 aboard the International Space Station. While aboard, the crew studied ways to reverse the aging of immune cells, how wounds heal in microgravity, and cardiovascular health. They also participated in spacewalks, tested new technology to diagnose medical conditions, explored the development of new construction materials in space, grew red dwarf tomatoes, and observed liquid behavior in artificial gravity to support missions to the Moon, Mars, and beyond.

2023年3月30日，NASA宇航员谢尔·林德格伦、杰西卡·沃特金斯和罗伯特·海因斯与华盛顿当地学生一起参加了STEM示范活动。林德格伦、海因斯和沃特金斯作为第67号和68号远征队的一部分，在国际空间站上度过了170天的太空生活。在国际空间站上，机组人员们研究了逆转免疫细胞老化的方法，伤口在微重力下如何愈合，以及心血管健康。他们还参加了太空行走，测试了诊断医疗状况的新技术，探索了太空中新型建筑材料的发展，种植了红色矮番茄，并观察了人工重力下的液体行为，以支持月球、火星和其他地方的任务。
