周四空间站轨道提升，太空行走准备与生物医学科学研究同步进行

Spacewalk Preps, Biomedical Science as Station Boosts Orbit on Thursday

国际空间站（International Space Station）正在为下周继续进行的外部维护工作进行太空行走准备。第75远征队（Expedition 75）的成员们在维护空间站系统运行的同时，也在持续进行生物医学研究。此外，一艘美国货运飞船于周四点火启动推进器，提升了空间站的轨道。

Preparations are ongoing for a spacewalk next week to continue external maintenance on the International Space Station. The Expedition 75 residents are also keeping up biomedical research while maintaining orbital outpost systems. Also, a U.S. cargo craft fired it thrusters on Thursday boosting the station’s orbit.

来自欧洲空间局（European Space Agency，ESA）的飞行工程师Sophie Adenot和美国国家航天局（NASA）的空间站指令长Jessica Meir正在研究将于9月1日周二美国东部时间上午7:30进行的太空行走程序。Adenot和Meir将在太空真空中工作约六个半小时，更换航天器导航辅助设备，为宇宙粒子探测器的未来升级做准备，安装用于增强数据中继系统的跳线电缆，以及执行其他任务。

Flight engineer Sophie Adenot of ESA (European Space Agency) and station commander Jessica Meir of NASA are studying the procedures they will use when they conduct a spacewalk scheduled for 7:30 a.m. EDT on Tuesday, Sept. 1. Adenot and Meir will spend about six-and-a-half hours in the vacuum of space replacing a spacecraft navigational aid, preparing a cosmic particle detector for future upgrades, installing jumper cables to boost data-relay systems, and other tasks.

周四，宇航员们与NASA飞行工程师Anil Menon和Jack Hathaway一同进行了程序审查，并与任务控制中心通话，讨论下周太空行走的细节并回答相关问题。Menon与他的三位同伴还研究了Canadarm2机械臂的操作程序，他将利用该机械臂在Meir执行太空行走任务时对其进行操纵。

The astronauts joined NASA flight engineers Anil Menon and Jack Hathaway during the procedure reviews on Thursday and called down to mission controllers to discuss details and answer questions for next week’s spacewalk. Menon, along with his three crewmates, also studied the Canadarm2 robotic arm procedures he will use to maneuver Meir as she conducts her spacewalking tasks.

周四的日程安排中包含了生命科学研究，旨在帮助医生持续监测机组人员的健康状况，以发现潜在的太空相关问题，并确保长期太空飞行的成功。Meir使用Ultrasound 3设备扫描了Menon的颈静脉并测量了他的血压，地面研究人员进行了实时（real time）监测。Adenot穿着EasyMotion-2套装进行了锻炼，该套装通过发送电脉冲触发肌肉收缩，以辅助太空锻炼。Hathaway对人体研究设施-1（Human Research Facility-1）和人体研究设施-2（Human Research Facility-2）机架内的医疗用品包进行了盘点。

Life science was booked into the crew’s schedule on Thursday helping doctors continuously monitor crew health to detect potential space-caused issues and ensure a successful long-duration spaceflight. Meir scanned Menon’s jugular veins using the Ultrasound 3 device and measured his blood pressure as researchers on the ground monitored in real time. Adenot exercised wearing the EasyMotion-2 suit that sends electrical impulses and triggers muscle contractions to supplement a space workout. Hathaway took inventory of medical supply kits inside the Human Research Facility-1 and Human Research Facility-2 racks.

俄罗斯国家航天集团（Roscosmos）宇航员Anna Kikina结束了24小时的监测任务，并取下了在她工作和睡眠期间追踪其心率和血压的电极。飞行工程师Pyotr Dubrov在轮班期间进行了生命保障（life support）维护，更换了Vozdukh二氧化碳（carbon dioxide）去除装置内的组件。飞行工程师Andrey Fedyaev开始了计算机硬件和固件更新的工作。当天结束时，Meir与Fedyaev会合，并用Ultrasound 3扫描了他的静脉，以进一步了解微重力对血液流动的影响。

Roscosmos cosmonaut Anna Kikina wrapped up a 24-hour monitoring session and removed electrodes that tracked her heart rate and blood pressure while she worked and slept. Flight engineer Pyotr Dubrov spent his shift on life support maintenance replacing components inside the Vozdukh carbon dioxide removal device. Flight engineer Andrey Fedyaev started his shift on computer hardware and firmware updates. At the end of the day, Meir joined Fedyaev and scanned his veins with the Ultrasound 3 for more insight into microgravity’s effect on blood flow.

诺斯罗普·格鲁曼公司（Northrop Grumman）的Cygnus XL货运飞船在停靠于Unity舱期间，于今日点火推进器20分43秒，提升了国际空间站的轨道。此次轨道提升使轨道实验室处于正确的轨道高度，以便迎接预计于9月初发射的进步号（Progress）96补给飞船的交会对接。

Northrop Grumman’s Cygnus XL cargo spacecraft fired its thrusters for 20 minutes, 43 seconds today while berthed to the Unity module lifting the International Space Station’s orbit. The orbital reboost places the orbiting lab at the correct altitude for the rendezvous and docking of the Progress 96 resupply ship due to launch in early September.
