Astronauts and Robotics Experts Finalize Dragon Departure Work

The three Expedition 58 crew members have finished packing the SpaceX Dragon cargo craft with science experiments and hardware today. Final preparations for the vehicle’s departure are now on hold while teams wait for favorable weather in the splashdown area for Dragon’s return.

Dragon was scheduled for departure early Thursday morning from the International Space Station but mission managers made the decision to delay departure. Managers are assessing the backup release date of Sunday, Jan. 13 for Dragon’s return to Earth.

Robotics controllers maneuvered the Canadarm2 robotic arm Wednesday and grappled Dragon while it was still attached to the Harmony module. Prior to Dragon departure, they will remotely uninstall Dragon from Harmony and slowly guide it to its release position.

Astronaut Anne McClain will be in the cupola when robotics experts command the Canadarm2 to release Dragon finalizing its mission at the orbital lab. She’ll monitor its departure while her crewmates Commander Oleg Kononenko and Flight Engineer David Saint-Jacques work on their daily science and maintenance tasks.

Dragon, which arrived at the station Dec. 8, will orbit Earth a few more hours on its own before reentering the atmosphere. It will parachute to a splashdown in the Pacific Ocean off the coast of southern California where SpaceX personnel will retrieve the space freighter. They’ll deliver it to shore where NASA engineers will extract the precious cargo for immediate shipment to investigators around the country for analysis.

Crew Wraps Up Science Packing After Robotic Arm Grips Dragon

The SpaceX Dragon space freighter is in the grips of the Canadarm2 robotic arm today as the Expedition 58 crew wraps up cargo transfers inside the vessel. The space trio is also on lab duty conducting a variety of microgravity research aboard the International Space Station.

Overnight, robotics controllers remotely commanded the Canadarm2 to grapple Dragon before its release from the Harmony module. Meanwhile, the hatches are still open and Flight Engineers Anne McClain and David Saint-Jacques continue loading time-critical space experiments inside the U.S. cargo craft.

The crew will shut the hatch to Dragon Wednesday and disconnect power cables. Then robotics controllers will take over, uninstall Dragon from Harmony overnight and maneuver it into release position. McClain will be in the cupola Thursday monitoring Dragon when it is released from the Canadarm2 around 4:35 a.m. EDT.

After its departure, Dragon will orbit Earth a few more hours before splashing down in the Pacific Ocean off the coast of southern California. SpaceX personnel will retrieve Dragon and return it to port where NASA engineers will extract the precious cargo for immediate shipment to investigators around the country.

Dragon Packed With Science Before Thursday’s Departure

The Expedition 58 crew members are packing the SpaceX Dragon space freighter ahead of its return to Earth on Thursday. Ground controllers are also readying communications gear and robotics systems prior to Dragon’s departure from the International Space Station.

Astronauts Anne McClain of NASA and David Saint-Jacques of the Canadian Space Agency are wrapping up final transfers of completed science experiments in Dragon today. The duo is loading science samples from several experiments for return to Earth, where they will quickly be delivered to investigators around the country for analysis.

Engineers on the ground are testing communications and control gear that will be used to monitor and command Dragon after its release from the station. Robotics controllers are also powering up the Canadarm2 robotic arm today to grapple Dragon before its removal from the Harmony module.

Dragon Departing Station Next Week; Crew Studies Biology

The SpaceX Dragon cargo craft is in its final week attached to the International Space Station’s Harmony module. Meanwhile, robotics experts on the ground and the crew aboard the lab are working a wide variety of science activities today.

The Dragon space freighter has nearly completed its cargo mission to replenish the orbital laboratory after delivering over 5,600 pounds of science and supplies Dec. 8. Dragon will return to Earth Jan. 10 for retrieval in the Pacific Ocean loaded with completed science experiments and used hardware for analysis.

New space exposure experiments are being remotely installed outside the station today using a specialized robotic hand known as Dextre. Also, astronauts Anne McClain and David Saint-Jacques collected biological samples today for stowage and later analysis. The duo then split up for more science work including testing crew brain function and removing science hardware that explores stem cells and other biological processes.
