The International Space Station turned 20 years old Nov. 20 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 Nov. 19 delivering almost 7,400 pounds of crew supplies and new science experiments. The Progress 71 (71P) resupply from Russia docked Nov. 18 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.
