After a Russian cargo ship departed the International Space Station Thursday, the Expedition 54 crew is wrapping up the final work week of 2017 orbiting Earth and conducting science. The six astronauts and cosmonauts will go into the last weekend of 2017 with light duty and family conferences before taking New Year’s Day off.
The Progress 67 (67P) resupply ship finished its stay six-and-a-half month at the station’s Zvezda service Thursday at 8:03 a.m. EDT. Cosmonauts Alexander Misurkin and Anton Shkaplerov packed the 67P full of trash the closed its hatches before it automatically undocked. It will re-enter Earth’s atmosphere and safely burn up over the south Pacific Ocean.
Japanese astronaut Norishige Kanai took his turn on the exercise bike today for a study researching physical exertion in space. Doctors measure the astronauts breathing and other parameters during exercise to ensure they have the strength to perform strenuous activities such as spacewalks and even emergency procedures.

Flight Engineer Scott Tingle of NASA was harvesting plants for the Advanced Plants Experiment-05 (APEX) and stowing the botany samples in a science freezer for further analysis. Scientists are exploring how plants respond to microgravity and observing molecular and genetic changes.
The life science studies help mission doctors keep astronauts healthier and stronger while living in outer space. Also, NASA is planning longer human missions beyond low-Earth orbit and learning how to keep crews self-sustainable.
Finally, three U.S. astronauts, two Russian cosmonauts and a Japanese astronaut on the orbital laboratory will experience New Year’s Eve 16 times as they orbit Earth once every 90 minutes. That is 16 sunrise and sunsets 250 miles above Earth. The crew will take the day off, share a meal and reflect on the past year and plan for the year ahead.
Russian Space Freighter Ends Stay at Station

Filled with trash, the unpiloted ISS Progress 67 Russian cargo ship undocked from the aft port of the Zvezda Service Module of the International Space Station at 8:03 p.m. EST. Just after 11 p.m., Russian flight controllers will send commands to fire the Progress’ engines and deorbit the space freighter, sending it to a destructive entry over the unpopulated south Pacific Ocean.
