The Expedition 74 crew opened the hatch to Northrop Grumman's Cygnus XL spacecraft on Tuesday and began unpacking new quantum physics equipment, a blood stem cell study, an advanced exercise system, and

The United States will work with industry and international partners to ignite a sustainable orbital economy and will maintain its presence in low Earth orbit

Moving toward a future where the agency becomes one of many customers for commercial stations

Maximizing research missions in low Earth orbit with commercial potential Helping industry mature technical and operational capabilities

Building on 25 years of continuous human presence in low Earth orbit, plans before the ISS is retired in 2030 include: Increasing support for commercial crew and cargo missions to the ISS

Current efforts are designed to preserve that legacy—expanding access, advancing scientific research, and opening the path to a new era of commercial space stations

For more than 25 years, the International Space Station has served as humanity's home in orbit.

From advancing lunar science to developing Orion spacecraft systems, the station's continuous presence in orbit is propelling deep space exploration

Research aboard the space station helped lay the foundation for Artemis II, the mission to send astronauts around the Moon 🌙

The crew prepared spacesuits, reviewed procedures on Tuesday, and carried out maintenance and science activities

Expedition 74 completed final preparations for tomorrow's spacewalk, when two NASA astronauts will exit the space station to perform a solar array upgrade

A scientist explains how a station is being used to study why some bacteria resist antibiotics and to help fight superbugs

Bone studies and robotics research conducted on the station are supporting efforts to maintain crew health and plan future missions to the Moon, Mars, and beyond.

Space station research contributed to a new FDA-approved cancer therapy, cutting treatment from a 2-hour port infusion to a 1–2 minute injection. The result is faster, simpler care for cancer patients

First two spacewalks of the year! On Jan. 8 and Jan. 15, NASA astronauts will head outside the station to prepare new roll-out solar arrays, replace a high-definition camera, and perform additional tasks

Exp 74 closed out the week with innovative brain and cardiac research examining how space affects cognition and heart health. Results could improve astronaut care and advance medical treatments on Earth

On Tuesday, Expedition 73 focuses on intensive scientific work, studying heart health, stem cells and physics to protect human health and shape future missions to the Moon, Mars and beyond

A cargo spacecraft has successfully docked with the International Space Station, and another is en route to continue resupplying the Expedition 73 crew.

The Cygnus XL cargo ship from Northrop Grumman activated its UltraFlex solar arrays, which resemble cymbals, roughly 90 minutes post-launch to supply power for its journey to the station.

Wednesday's agenda for Expedition 73 involved cardiac research, a bone analysis, and projects on space agriculture, while preparations for two station resupply missions continued.
