A new shipment of crew supplies and science experiments is packed inside the Orbital ATK Cygnus spacecraft ready for liftoff today at 5:55 p.m. The Cygnus will launch on top of an Atlas V rocket from a launch pad located at the Cape Canaveral Air Force Station in Florida. Cygnus is scheduled to arrive at the International Space Station Sunday morning where astronaut Kjell Lindgren will capture the supply ship with Canada’s 57.7 foot robotic arm.

The crew is busy in the orbital lab today exploring the effects of space on life and preparing for Cygnus and a mid-December crew swap.

Scientists are observing Commander Scott Kelly and comparing his body to his twin brother ex-astronaut Mark Kelly. The Twins study seeks to understand how a body in space differs from a similar body on Earth. Kelly also joined fellow crew members Lindgren and Kimiya Yui for eye checks.

Yui and Lindgren also worked with cosmonaut Oleg Kononenko preparing for their Dec. 11 return to Earth ending the Expedition 45 mission. Three new station crew members are preparing to launch Dec. 15.

Veteran cosmonauts Sergey Volkov and Mikhail Kornienko continued studying how blood flows while living in space. Volkov then researched the vibration levels on the station and their possible impacts on operations. Kornienko was back at work exploring advanced Earth photography techniques.

Station Ramping Up for New Crew and New Supplies

A trio of International Space Station residents is getting ready to return to Earth while a new crew in Kazakhstan is preparing to replace them. Meanwhile, a pair of space freighters, the Orbital ATK Cygnus and Russia’s Progress 62 (62P), is being readied for liftoff as another docked cargo craft is being packed before it’s undocking.

The Orbital ATK Cygnus cargo craft will launch Thursday at 5:55 p.m. EST to the station. The 61P is scheduled for a Dec. 21 liftoff. While mission managers are preparing three different spacecraft for launch this month, the Expedition 45 crew is performing research to help scientists benefit life on Earth and crews in space.

The next home-bound astronauts Kjell Lindgren and Kimiya Yui checked their vision and blood pressure today for the Ocular Health study. The duo will return home with Soyuz Commander Oleg Kononenko Dec. 11 officially ending the Expedition 45 mission. Kononenko participated in a pair of blood circulation experiments, Cosmocard and Cardiovector, and prepared the Soyuz TMA-17M spacecraft for its departure in less than two weeks.

Commander Scott Kelly, who is staying in space until March with Flight Engineer Sergey Volkov and fellow One-Year crew member Mikhail Kornienko, sampled and tested the station’s water quality. Volkov and Kornienko explored veins in the lower body to understand blood flow during a long-term space mission.

The next crew to live on the space station, Expedition 46, is at the Baikonur Cosmodrome launch site counting down to its Dec. 15 liftoff inside the Soyuz TMA-19M rocket. First-time British astronaut Timothy Peake is joining veteran station crew members Timothy Kopra and Yuri Malenchenko for the six-month mission aboard the orbital laboratory.

The International Space Station residents are gearing up to host the Orbital ATK Cygnus space freighter when it arrives Dec. 6. On the ground, a new trio of Expedition 46-47 crew members headed to their launch site at the Baikonur Cosmodrome in Kazakhstan before their mid-December mission.

NASA astronauts Scott Kelly and Kjell Lindgren trained for the rendezvous and robotic capture of Cygnus after its Dec. 3 launch from the Kennedy Space Center. The Cygnus will deliver supplies for the crew and new science experiments Dec. 6 when it is captured and berthed to the Unity module.

Three new station crew members are in the final stage of their mission training before beginning a six-month mission to the orbital laboratory. First-time British astronaut Timothy Peake will join veteran station residents Yuri Malenchenko and Timothy Kopra inside the Soyuz TMA-19M spacecraft for a six-hour ride to the space station set for Dec. 15.

Meanwhile, advanced space science continued today as the crew explored radiation, blood circulation and microbes living on crew members. Scientists hope to use the results from the many experiments on the station to benefit people on Earth and future crews.

Finally, the crew is packing the Soyuz TMA-17M spacecraft before its undocking Dec. 11. The Soyuz will bring home Expedition 45-46 crew members Lindgren, Soyuz Commander Oleg Kononenko and Japanese astronaut Kimiya Yui.

Station Crew Getting Ready for Heavy Traffic Before Christmas

International Current Space Station Configuration

The current space station configuration has two Soyuz crew spacecraft and two Progress resupply ships docked at the orbital laboratory. View the station overview page.

Crews and cargo shipments will be coming and going at the International Space Station during a busy December in space. Two resupply ships will arrive, one cargo craft will leave and an Expedition 45 trio will head home before an Expedition 46 trio replaces it.

Commander Scott Kelly teamed up with Flight Engineer Kjell Lindgren for more robotics training before the Dec. 3 launch and Dec. 6 arrival of the Orbital ATK Cygnus cargo craft. When Cygnus arrives it will be captured with the Canadarm2 robotic arm and berthed to the Unity module.

Meanwhile, Lindgren along with Japanese astronaut Kimiya Yui and Soyuz Commander Oleg Kononenko are preparing for their Dec. 11 landing. On the ground in Russia, their Expedition 46 replacements Soyuz Commander Yuri Malenchenko and Flight Engineers Timothy Kopra and Timothy Peake are counting down to their Dec. 15 launch. A docked Progress 61 resupply ship will fire its engines Wednesday raising the station’s orbit to accommodate the mid-December crew swap.

The Cygnus cargo craft is in Florida at the Kennedy Space Center being processed before its early December launch atop an Atlas V rocket. Russia’s Progress 60 (60P) cargo craft will undock from the Pirs docking compartment Dec. 19. A new Progress 62 resupply ship will replace the 60P when it arrives at Pirs Dec. 23.

In two weeks, NASA astronauts Scott Kelly and Kjell Lindgren will step outside the U.S. Quest airlock for the first of two maintenance spacewalks. The International Space Station is also being readied to host the next Orbital ATK Cygnus cargo mission set for early December.

Japanese astronaut Kimiya Yui has been servicing the two spacesuits Kelly and Lindgren will wear on the two six-hour spacewalks scheduled for Oct. 28 and Nov. 6. The spacewalkers will lubricate the tip of the International Space Station’s robotic arm, Canadarm2. He and Lindgren started their day, though, with eye checks for the ongoing Ocular Health study.

Kelly and Lindgren have also been preparing the Unity module where the Cygnus commercial cargo craft will be attached when it arrives in December after a 14-month hiatus. Kelly installed a Unity power adapter in the Destiny lab module then joined Lindgren to adjust power connectors inside Unity.

The three cosmonauts continued their routine maintenance tasks and science experiments in the station’s Russian segment. Flight Engineer Sergey Volkov explored crystal magnetism, while Oleg Kononenko and Mikhail Kornienko studied how a crew member adapts to motion during a spaceflight.
