The SpaceX Dragon cargo spacecraft was released from the International Space Station’s robotic arm at 2:10 p.m. EST. The capsule was maneuvered outside the vicinity of the space station in preparation for its return trip to Earth. The capsule is currently scheduled to splashdown in the Pacific Ocean at about 7:44 p.m., 259 miles southwest of Long Beach, California.

Robotics controllers on the ground removed the SpaceX Dragon from the Harmony node Tuesday morning after they finished packing it full of critical research and gear Monday. Italian astronaut Samantha Cristoforetti, backed up by Flight Engineer Terry Virts, commanded the Canadarm2 to release Dragon.

Cristoforetti also worked on orbital plumbing during the day before heading to the cupola for the release. Earlier, Commander Butch Wilmore and Virts demated the jumper cables and depressurized the vestibule which is the interface between Harmony and Dragon. The NASA astronauts also had time set aside to organize tools ahead of three spacewalks to install cables the first of which is set to begin Feb. 20.

The cosmonauts continued their work conducting Russian science and stowing trash and gear inside the ISS Progress 57 (57P) resupply ship.

Meanwhile, a trio of cosmonauts worked in the Russian segment of the International Space Station on their set of science investigations. They studied ways to locate punctures caused my micro-meteoroids on the Russian side of the station; they looked at the behavior of charged macroparticles inside a magnetic trap; they also explored crew training methods using interactive 3D manuals, or virtual manuals.

Another resupply spacecraft is counting down to its undocking from the space station this weekend. Europe’s Automated Transfer Vehicle-5 (ATV-5) is set to undock from the Zvezda service module Saturday for a fiery deorbit over the Pacific about two weeks later. Italian astronaut Samantha Cristoforetti installed internal cameras inside the ATV-5 that will record its breakup during the reentry. Engineers will use this data to understand the mechanics of a deorbiting spacecraft.

Back inside the International Space Station, the crew is working on more visiting vehicle activities, spacewalk preparations as well as ongoing microgravity science.

Commander Barry Wilmore is loading Europe’s Automated Transfer Vehicle-5 (ATV-5) with trash readying the vehicle for its departure Feb. 14. Cosmonauts Alexander Samokutyaev and Anton Shkaplerov practiced using the telerobotically operated rendezvous system, or TORU, ahead of the Feb. 17 arrival of the ISS Progress 58 resupply ship. The TORU would be used in the unlikely event the Kurs automated rendezvous system failed during the Progress’ approach.

Wilmore also harvested plants for the APEX-03 botany experiment. That study observes the effects of microgravity on the development of roots and cells on plant seedlings. Italian astronaut Samantha Cristoforetti looked at roundworms for the Epigenetics study that researches if new cell generations adapt to microgravity.
