Crew Unpacking New U.S., Russian Cargo Ships on Station’s 20th Anniversary

Zarya Module
The International Space Station’s first element, the Zarya module, is pictured in December 1998 as space shuttle Endeavour approached.

The International Space Station turned 20 years old today with the launch of the first element, the Zarya module, occurring on Nov. 20, 1998. The three-person Expedition 57 crew commemorated the beginning of the orbital lab’s construction during a Facebook Live event today and answered questions submitted via social media.

The crew also continues to unpack the newest U.S. and Russian cargo ships to visit the International Space Station today.

The Cygnus space freighter from Northrop Grumman arrived Monday delivering almost 7,400 pounds of crew supplies and new science experiments. The Progress 71 (71P) resupply from Russia docked Sunday packed with almost three tons of food, fuel and supplies

Astronauts Serena Auñón-Chancellor and Alexander Gerst opened Cygnus’s hatch a few hours after it was captured and attached to the Unity module. Today they are installing new science freezers, transferring the new cargo and replenishing the orbital laboratory. Cosmonaut Sergey Prokopyev opened the 71P hatch after its automated docking Sunday and began unloading the new gear.

In between all the cargo work today, the three-person crew had time to conduct science and maintain station systems.

Gerst photographed samples for a physics study that is observing how quartz/clay particles interact in microgravity. Results could benefit future planetary studies and the petroleum industry. Auñón-Chancellor measured light levels in the Columbus lab module for a study researching how new station lights impact crew wellness. Prokopyev worked primarily in the station’s Russian segment maintaining life support systems.

  1. What type of scientology are you on? I truthfully respect your right to an opinion, but thats some level 3 super genius dropping acid in the griffith park observatory type stuff.

    1. One of the biggest challenges is getting time-sensitive science experiments offloaded from the cargo ship and placed into research racks on the space ship. Packing and unpacking a space cargo ship is a bit like a 3D puzzle since everything has to be packed according to mass, volume and location. The Dragon spacecraft can launch science freezers to the station with samples for research on the station. Those same freezers can be returned with samples for analysis on Earth.
