Cygnus XL Cargo Craft Launches to Resupply Expedition 74 Crew

Northrop Grumman’s Cygnus XL cargo spacecraft sits atop a SpaceX Falcon 9 rocket counting down to a launch targeted at 7:41 a.m. EDT on Saturday to resupply the Expedition 74 crew. Packed with over 11,000 pounds of lab hardware, science experiments, and crew supplies, Cygnus XL is due to arrive at the International Space Station where it will be captured with the Candarm2 robotic arm on Monday.

A packed schedule filled with numerous science objectives and critical lab maintenance tasks greeted the Expedition 74 crew aboard the International Space Station on Thursday. Meanwhile, the orbital residents await the next U.S. cargo mission.

NASA, Northrop Grumman, and SpaceX now are targeting no earlier than 7:41 a.m. EDT Saturday, April 11, for the next Cygnus XL and Falcon 9 launch opportunity to resupply the International Space Station. Teams adjusted the Friday, April 10, launch opportunity due to forecasted inclement weather at Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. 

Four Expedition 74 astronauts had a ship-to-ship call with the four Artemis II astronauts on Tuesday after they flew around the Moon in a historic first for NASA and its international partners. The International Space Station residents also continued their ongoing biomedical research, trained to capture a U.S. cargo craft, and installed a small experimental robotic arm.

NASA, Northrop Grumman, and SpaceX now are targeting no earlier than 8:03 a.m. EDT Friday, April 10, for the next Cygnus XL and Falcon 9 launch opportunity to resupply the International Space Station. Teams adjusted the Wednesday, April 8, launch opportunity due to forecasted inclement weather at Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. 

The Expedition 74 crew continues preparing for the next U.S. cargo mission due to visit the International Space Station. The orbital residents also serviced spacesuits, configured scientific hardware, and studied how microgravity affects blood pressure at the beginning of the week.

Spacesuit work and eye checks wrapped up the week for the Expedition 74 crew aboard the International Space Station. The orbital residents also focused on robotics, cargo transfers, and science hardware maintenance at the end of the week.

The Expedition 74 crew studied how the brain receives signals in space and demonstrated advanced technology to remove humidity from spacecraft on Thursday. Other activities aboard the International Space Station included servicing a metal 3D printer and continuing to unpack a cargo resupply ship.

Medical tests and microbiology topped the research schedule for the Expedition 74 crew aboard the International Space Station on Tuesday. The seven crewmates also worked on spacesuits, cargo operations, and life support maintenance.
