NASA EXPRESS Racks Achieve 1 Million Hours of Service on Space Station

NASA astronaut Kayla Barron monitors experiments in one of the International Space Station’s 12 EXPRESS Racks during Expedition 66, which ran from October 2021 to March 2022. As many as 100 experiments at a time can be simultaneously conducted in the station’s full complement of racks, helping NASA achieve 1 million hours of powered EXPRESS Rack duty between 2001-2022.

NASA science research on the International Space Station reached an extraordinary milestone June 14.

The vital, versatile EXPRESS Racks – properly known as “EXpedite the PRocessing of Experiments to the Space Station” multipurpose payload shelving units – logged 1 million hours of combined powered duty on station. That’s the equivalent of nearly 115 years’ worth of scientific research completed in just two decades.

HUNTSVILLE, Ala. (NASA PR) — Ask International Space Station facility engineers and payload operations teams at NASA’s Marshall Space Flight Center in Huntsville, Alabama, what makes them proudest as they look back on two decades of developing and testing science hardware and providing real-time support for experiments on orbit. Many will instinctively glance upward, as if the source of that pride might be passing overhead at that moment, 250 miles up.

Just as often though, they look to one another.

HUNTSVILLE, Ala. (NASA PR) — Flying silently through the void of space around a globe of blue and green is the most advanced science laboratory ever developed: the International Space Station. Inside humanity’s orbiting outpost is a buzz of activity as explorers, pilots, doctors, and scientists from around the world conduct experiments, maintain the facility, and develop new technologies.
