<\/a><\/figure>The Expedition 74<\/a> crew continued its spacewalk preparations on Tuesday while keeping up vascular health research and artificial intelligence studies. Mission managers have also given the go for the departure of a U.S. cargo spacecraft from the International Space Station<\/a> this week.<\/p>\n NASA flight engineer Jessica Meir<\/a> tried on her spacesuit today with assistance from fellow NASA flight engineer Jack Hathaway<\/a> inside the Quest airlock<\/a>. The duo confirmed that the spacesuit is airtight and properly configured and assessed its comfort and mobility. Afterward, flight engineers Chris Williams<\/a> of NASA and Sophie Adenot of ESA (European Space Agency) joined the pair and called down to mission controllers for a spacewalk procedures review. Earlier, Williams prepared a helmet for installation on a spacesuit while Adenot trained to use the Canadarm2 robotic arm<\/a> to support the spacewalkers.<\/p>\n Meir and Williams are preparing for an upcoming spacewalk to ready the orbital outpost for a new roll-out solar array. The duo will spend about six-and-a-half-hours in the vacuum of space installing a modification kit and routing cables on the port side of the orbital outpost for the future roll-out solar array. The station\u2019s seventh roll-out solar array will be installed on a later spacewalk to augment the main solar arrays\u2019 power generation capabilities.<\/p>\n Cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev joined each other again on Tuesday and applied sensors to their forehead, fingers, and toes that sent their blood flow data by Bluetooth adaptor to a laptop computer where it was recorded for analysis. Doctors will use the biomedical data to understand how living in space affects vascular health.<\/p>\n Kud-Sverchkov also cleaned and inspected the Zvezda service module<\/a>\u2019s ventilation system. Mikaev took turns with Roscosmos flight engineer Andrey Fedyaev continuing to test artificial intelligence tools as a way to improve crew operations and communications with mission controllers. Fedyaev earlier spent time inside the Nauka science module<\/a> replacing orbital plumbing components, inspecting its ventilation system, and measuring the airflow.<\/p>\n Mission managers have approved the departure of Northrop Grumman\u2019s Cygnus XL spacecraft<\/a> for 7:05 a.m. EDT on Thursday after nearly six months attached to the Unity module<\/a>. Robotics controllers will remotely command the Canadarm2 to uninstall Cygnus from Unity then release it into Earth orbit for a fiery, but safe reentry above the South Pacific Ocean two days later.<\/p>\n NASA\u2019s live coverage of undocking and departure begins at 6:45 a.m. on\u00a0NASA+<\/a>,\u00a0Amazon Prime<\/a>, and the agency\u2019s\u00a0YouTube<\/a>\u00a0channel.
