Expedition 46 astronauts Scott Kelly and Tim Kopra of NASA commanded the International Space Station’s Canadarm2 robotic arm to release the Cygnus spacecraft at 7:26 a.m. EST while the space station was flying above Bolivia. Earlier, ground controllers at NASA’s Johnson Space Center had maneuvered Cygnus into place for its departure.

Once the spacecraft is a safe distance from the station, its engines will fire twice, pushing it into Earth’s atmosphere where it will burn up over the Pacific Ocean. The deorbit burn and re-entry of Cygnus will not air on NASA TV.

The Cygnus resupply craft arrived to the space station on Dec. 9, following Dec. 6 launch on a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida, for the company’s fourth NASA-contracted commercial station resupply mission.

Experiments delivered on Cygnus supported NASA and other research investigations during Expeditions 45 and 46, in areas such as biology, biotechnology, and physical and Earth science — research that impacts life on Earth.

The crew aboard the International Space Station is set to say farewell to a pair of spaceships over the next several days. The first spaceship, Orbital ATK’s Cygnus cargo craft, is being readied for its release Friday morning. After that, the Soyuz TMA-18M spacecraft will return to Earth March 1 bringing home three crew members.

Mission controllers in Houston are finalizing preparations before the 57.7 foot Canadarm2 robotic arm detaches Cygnus from the Unity module. NASA astronauts Scott Kelly and Tim Kopra will command the Canadarm2 to release Cygnus at 7:25 a.m. EDT Friday. Finally, Orbital ATK controllers in Virginia will command Cygnus to move away from the station and head towards Earth to burn up high in the atmosphere over the Pacific Ocean.

Kelly, along with cosmonaut Mikhail Kornienko, is in his final days of a mission that began in March of last year. The pair will take a ride home with three-time station resident Sergey Volkov who has been aboard the orbital lab since September. When the trio lands in Kazakhstan March 1, Kelly and Kornienko will have lived in space continuously for 340 days. Volkov’s mission will have lasted 182 days.

While the crew is busy with spacecraft departure activities, British astronaut Tim Peake worked on a variety of experiments today. He partnered with Kopra on a pair of experiments, one looking at how astronauts work on detailed interactive tasks and another researching cognitive performance. Peake also studied the thermophyscial properties of different metals inside Japan’s Electrostatic Levitation Furnace.

The International Space Station raised its orbit again today as three crew members prepare for a March 1 landing while another trio gets ready for a March 18 launch. Meanwhile, advanced research continued inside the orbital laboratory to improve life on Earth and for future space residents.

Today’s orbital reboost places the station at the correct altitude for the March 1 undocking of Soyuz Commander Sergey Volkov and One-Year crew members Scott Kelly and Mikhail Kornienko. Their undocking will leave the Poisk module’s docking port vacant where a trio of Expedition 47 crew members will dock two-and-a-half weeks later inside the Soyuz TMA-20M spacecraft.

Today, the Expedition 46 crew participated in a variety of human research exploring how the heart adapts to life in space, the risk of atherosclerosis in astronauts and how microgravity affects an astronaut’s vision. The crew also sampled the station’s air and surfaces for microbes to learn how to prevent contamination in future spacecraft.

Another spacecraft is being prepared for departure Friday morning when it will be released from the grips of the 57.7 foot long Canadarm2 robotic arm. The Orbital ATK Cygnus cargo craft is being loaded with trash before NASA astronauts Kelly and Tim Kopra release Cygnus using the robotics controls inside the seven-window cupola. NASA Television will cover the activities live Friday beginning at 7 a.m. EST.
