2022年5月27日星期五,国际空间站远征67号乘员组继续其正在进行的人类研究,进行超声眼科检查和大脑血流测量,轨道上的研究人员还探索了机器人技术和空间导航技术。国际空间站上的四名宇航员周五上午轮流使用超声2号设备扫描对方的眼部。

飞行工程师Kjell Lindgren, Bob Hines, Samantha Cristoforetti和Jessica Watkins聚集在哥伦布实验室舱内,在地面人员的实时支持下进行眼睛扫描。结果将帮助医生了解在失重状态下生活对眼睛、视网膜和视觉的影响。

早些时候,Hines完成了一项要求他佩戴电极和传感器监测其头部和胸部血流的训练。大脑自动调节调查正在探索人类大脑如何在微重力条件下调节其血液流动。研究结果可能有利于那些回到地球引力后出现头晕目眩和血压变化的宇航员。

Watkins在"希望"号实验舱内开启了一个Astrobee机器人自由飞行器,在为学生举办的"希望"号机器人编程挑战赛3之前测试其自主机动性。Lindgren在空间站圆顶中安装了一台相机,为一项研究拍摄月球图像,这可能有助于未来的阿特米斯宇航员在月球表面的导航。

Cristoforetti在上午将AstroPi计算机从和谐号舱转移到哥伦布舱。然后,她花了一个下午的时间来检查机器人控制系统,然后终止了锂离子电池充电操作。

指挥官Oleg Artemyev与飞行工程师Denis Matveev一起,在周五更换了Zvezda服务舱的跑步机振动隔离系统上的部件。飞行工程师Sergey Korsakov周五在两个不同的俄罗斯实验中工作,一个是探索心血管系统对微重力的适应,另一个是研究先进的地球摄影技术。

Flight engineers Kjell Lindgren, Bob Hines, Samantha Cristoforetti and Jessica Watkins gathered in the Columbus laboratory module to conduct eye scans with real-time support from ground personnel. The results will help doctors understand the effects of living in weightlessness on the eyes, retina and vision.

Earlier, Hines completed a training that required him to wear electrodes and sensors to monitor his head and chest blood flow. The brain autoregulation survey is exploring how the human brain regulates its blood flow under microgravity. The results may benefit astronauts who experience dizziness and changes in blood pressure when they return to gravity.

Watkins opened an Astrobee Robot Free vehicle in the experimental module & quot; Hope & quot; to test its autonomous maneuverability before the quot; Hope & quot; Robot programming Challenge 3 for students. Lindgren has installed a camera in the dome of the space station to take images of the moon for a study that could help future Artemis astronauts navigate the lunar surface.

Cristoforetti transferred the AstroPi computer from the Harmony module to Columbus module in the morning. Then she spent the afternoon checking the robot control system and then terminated the lithium-ion battery charging operation.

Commander Oleg Artemyev, along with flight engineer Denis Matveev, replaced parts on the treadmill vibration isolation system in the Zvezda service module on Friday. Flight engineer Sergey Korsakov worked in two different Russian experiments on Friday, one to explore the adaptation of the cardiovascular system to microgravity, and the other to study advanced earth photography.
