ISS Expedition 74 Crew Kicks Off Week With Cygnus Cargo Training and Spacewalk Cleanup
摘要： 国际空间站第 74 远征队乘组开始为诺斯罗普·格鲁曼 Cygnus XL 货运飞船的到来进行训练，维护上周太空行走使用的宇航服，并开展了紧急医疗演习。
Cygnus XL Cargo Mission Preparation
Expedition 74 astronauts are preparing for the arrival of Northrop Grumman's Cygnus XL cargo spacecraft, targeted for launch no earlier than April 8 at 8:49 a.m. EDT. NASA flight engineers Chris Williams and Jack Hathaway reviewed the upcoming mission, trained for rendezvous procedures, and familiarized themselves with monitoring equipment.
Cygnus will deliver advanced microgravity research gear to study:
- Quantum physics in microgravity
- Stem cell therapies
- Astronaut health monitoring systems
Post-Spacewalk Spacesuit Servicing
NASA flight engineer Jessica Meir spent Monday servicing the spacesuits she and Williams wore during a 7-hour, 2-minute spacewalk on March 18 (EVA 94). She:
- Cleaned and flushed the suit's water-cooling loops that regulate body temperature
- Emptied and refilled the water system to remove gas bubbles and contaminants
Science and Operations
ESA flight engineer Sophie Adenot focused on multiple scientific experiments:
- Collecting data from an investigation studying ways to quickly download large amounts of data from space
- Swapping research samples inside a science freezer
- Inventorying biomedical gear used for cardiovascular health studies
- Recording a video message for students describing the importance of space science
Emergency Drill
All four astronauts joined Roscosmos cosmonaut Andrey Fedyaev for a mid-afternoon emergency medical drill, reviewing:
- Locations and use of medical hardware
- CPR (cardiopulmonary resuscitation) procedures
- Individual roles during medical emergencies in low Earth orbit
Roscosmos Segment Activities
- Andrey Fedyaev: Replaced smoke detectors and gas masks in the Nauka science module; checked drinking water quality
- Sergey Kud-Sverchkov (Station Commander): Serviced electrical components and checked the Elektron oxygen generator in Zvezda service module; studied AI tools for improving crew operations
- Sergei Mikaev: Offloaded supplies from Progress 94 resupply ship that docked March 24
