Europe’s Automated Transfer Vehicle-5 (ATV-5) is being packed with its final load of trash and discarded gear. The ATV-5 will undock from the Zvezda service module’s aft-end port Saturday at 8:40 a.m. EST. It will descend into the Earth’s atmosphere over the Pacific Ocean for a fiery demise Sunday afternoon.

A new resupply ship, the ISS Progress 58, is being loaded with final gear to be delivered Feb. 17 to Expedition 42 when it launches from the Baikonur Cosmodrome in Kazakhstan. The Roscosmos space freighter will orbit the Earth just four times, or about six hours, after launch before docking to the port vacated by ATV-5.

The station crew also focused on spacewalk preparations and microgravity science, the primary mission of the orbital laboratory, to benefit life on Earth as well as future space crews. Ground doctors assisted Commander Barry Wilmore and Italian astronaut Samantha Cristoforetti during eye exams. Cosmonauts Alexander Samokutyaev and Elena Serova studied bioelectric cardiac activity as well as methods to locate punctures caused by micro-meteoroids on the station’s surface.

Meanwhile, another spacecraft is preparing to end its stay at the International Space Station. Europe’s fifth and final Automated Transfer Vehicle-5 is being prepared for its undocking from the Zvezda service module Saturday morning. It will reenter Earth’s atmosphere on Sunday afternoon and burn up over the Pacific Ocean.

Dragon Splashes Down Ending SpaceX Mission

SpaceX’s Dragon cargo spacecraft splashed down in the Pacific Ocean at about 7:44 p.m. EST 259 miles southwest of Long Beach, California, marking the end of the company’s fifth contracted cargo resupply mission to the International Space Station.

The spacecraft is returning about 3,700 pounds of NASA cargo and science samples from the International Space Station. A SpaceX vessel will take the Dragon spacecraft to Long Beach, where some cargo will be removed and returned to NASA. Dragon will be prepared for a return journey to SpaceX’s test facility in McGregor, Texas, for processing.

The mission was the fifth of 12 cargo resupply trips SpaceX will make to the space station through 2016 under NASA’s Commercial Resupply Services contract.

Dragon Conducts Deorbit Burn, Splashdown Next

Dragon conducted its deorbit burn on time at 5:49pm Central time, 6:49pm Eastern time and is headed for its parachute-assisted splashdown in the Pacific some 259 statute miles southwest of Long Beach, California. Splashdown time remains approximately 6:44pm Central time, 7:44pm Eastern time (4:44pm at the splashdown site, about 2 hours, 4 minutes before sunset).

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.
