Dragon Attached to Station for Cargo Transfers

Dragon Installed to Harmony Module
The SpaceX Dragon resupply ship is installed to the Harmony module. The Progress 66 cargo craft is docked to the Pirs docking compartment and the Soyuz MS-04 crew vehicle is docked to the Poisk module.

A little over two hours after it was captured by Expedition 52 Flight Engineers Jack Fischer and Peggy Whitson, the unpiloted SpaceX Dragon cargo craft was attached to the Earth-facing side of the Harmony module of the International Space Station. Ground controllers at Mission Control, Houston reported that Dragon was bolted into place at 12:07 p.m. EDT as the station flew 258 statute miles over central Kazakhstan.

Earlier, the Dragon was grappled by Fischer and Whitson using the Canadarm2 robotic arm at 9:52 a.m. EDT at the completion of a flawless two-day journey for the resupply vehicle following its launch atop a SpaceX Falcon 9 rocket from the Kennedy Space Center, Florida on Saturday.

The station crew expects to open Dragon’s hatch later today to begin transferring time-critical scientific experiments. Dragon will remain attached to the complex until July 2, when it will be detached from Harmony and robotically released for its deorbit back into the Earth’s atmosphere and a parachute-assisted splashdown in the Pacific Ocean.

While the International Space Station was traveling about 250 miles over the south Atlantic ocean east of the coast of Argentina, Flight Engineers Jack Fischer and Peggy Whitson of NASA captured Dragon a few minutes ahead of schedule at 9:52 a.m. EDT.

Following its capture, the SpaceX Dragon cargo ship will be maneuvered by ground controllers operating the International Space Station’s robotic arm for installation onto the Earth-facing port of the Harmony module.

Cygnus Departs Station Day Before Dragon Arrives

Cygnus Departure

Expedition 52 Flight Engineer Jack Fischer of NASA commanded the International Space Station’s Candadarm2 robotic arm to release the Cygnus spacecraft at 9:10 a.m. EDT while the space station was flying above the south Atlantic Ocean. Earlier, ground controllers detached Cygnus from the station and maneuvered it into place for its departure.

The spacecraft spent 44 days at the station after delivering approximately 7,600 pounds of supplies and science experiments to the orbiting laboratory and its Expedition 51 and 52 crew members for Orbital ATK’s seventh NASA-contracted commercial resupply mission.

Dubbed the “SS John Glenn” after the iconic Mercury and shuttle astronaut and U.S. Senator from Ohio, Cygnus will remain in orbit for a week in support of the SAFFIRE experiment and the deployment of four small Nanoracks satellites before Orbital ATK flight controllers send commands June 11 to deorbit the spacecraft for its reentry into the Earth’s atmosphere, where it will burn up over the Pacific Ocean. NASA TV will not provide a live broadcast of the Saffire experiment or the Cygnus deorbit burn and reentry, but imagery from Saffire will be posted on NASA.gov as it becomes available.

As Cygnus departs, the SpaceX Dragon spacecraft launched yesterday will close in on the station for its capture by Fischer and Whitson Monday, June 5. Using the Canadarm2 robotic arm, they will grapple the SpaceX cargo spacecraft at 10 a.m. NASA TV coverage will begin at 8:30 a.m.

The Falcon 9 rocket lifted off at 5:07 p.m. EDT, and Dragon has begun its journey to the International Space Station with an arrival scheduled for June 5. Dragon separated from Falcon 9 about 10 minutes after launch, and solar arrays successfully deployed shortly after separation from the second stage. A post-launch news conference is scheduled to begin on NASA TV at approximately 6:30 p.m.

Before Dragon arrives at the space station, the Orbital ATK Cygnus cargo spacecraft will depart the station Sunday, June 4. Expedition 52 Flight Engineers Jack Fischer and Peggy Whitson of NASA will be at the controls of the Canadarm2 robotic arm to release Cygnus at 9:10 a.m. NASA TV coverage of the spacecraft’s departure will begin at 8:30 a.m.

Expedition 51 Crew Back on Earth After 196 Days

Soyuz MS-03 Landing

After spending 196 days in space, Expedition 51 crew members Oleg Novitskiy of Roscosmos and Thomas Pesquet of ESA (European Space Agency) landed their Soyuz MS-03 spacecraft in Kazakhstan at approximately 10:10 a.m. EDT. Russian recovery teams are helping the crew exit the Soyuz vehicle and adjust to gravity after their stay in space.

The duo arrived at the International Space Station on Nov.19, 2016, along with NASA’s Peggy Whitson, who will remain on the space station and return home with NASA’s Jack Fischer and Roscosmos’ Fyodor Yurchikhin. That landing is targeted for September.

At the time of undocking, Expedition 52 began aboard the station under Yurchikhin’s command. Along with Whitson and Fischer of NASA, the three-person crew will operate the station until the arrival of three new crew members. Randy Bresnik of NASA, Sergey Ryazanskiy of Roscosmos, and Italian astronaut Paolo Nespoli of ESA are scheduled to launch July 28 from Baikonur, Kazakhstan.

The Expedition 51 crew members are awaiting a new space shipment and getting ready for new science experiments. The crew is also preparing for the departure of a pair of International Space Station flight engineers.

The Falcon 9 rocket that will launch the SpaceX Dragon cargo craft to space is resting at its launch pad today at the Kennedy Space Center in Florida. Dragon will lift off Thursday at 5:55 p.m. EDT on a three-day trip to the station’s Harmony module.

Inside the commercial space freighter is nearly 6,000 pounds of crew supplies, station hardware and science experiments. One of those experiments, Cardiac Stem Cells, will research how stem cells affect cardiac biology and tissue regeneration in space. The station’s Microgravity Science Glovebox is being readied for the study which may provide insight into accelerated aging due to living in microgravity.

On Friday, cosmonaut Oleg Novitskiy will command the Soyuz MS-03 spacecraft to return him and European Space Agency astronaut Thomas Pesquet back to Earth after 196 days in space. The two crew members are packing their spacecraft with research samples, hardware and personal items for the near 3.5 hour ride home. The duo will undock from the Rassvet module at 6:47 a.m. EDT. They will then parachute to a landing in Kazakhstan at 10:10 a.m. (8:10 p.m. Kazakh time).

The International Space Station is preparing this week for the departure of two Expedition 51 crew members and the arrival of the SpaceX Dragon.

Expedition 52 will begin Friday morning when two Expedition 51 crew members depart the station inside the Soyuz MS-03 spacecraft. Cosmonaut Oleg Novitskiy and astronaut Thomas Pesquet will return to Earth and parachute to landing in Kazakhstan after a 196-day mission in space.

NASA astronauts Peggy Whitson and Jack Fischer along with cosmonaut Fyodor Yurchikhin will continue their stay aboard the orbital complex. Whitson will hand over station command to Yurchikhin the day before the Expedition 51 crew leaves.

Dragon is due to launch Thursday at 5:55 p.m. EDT atop a Falcon 9 rocket for a three-day trip to the space station. NASA astronaut Jack Fischer will command the Canadarm2 to grapple Dragon when it arrives Sunday morning. Afterward, robotics controllers on the ground will remotely install Dragon to the Harmony module.

Dragon is hauling nearly 6,000 pounds of cargo to the station including new science payloads, crew supplies, vehicle hardware, spacewalk equipment and computer gear. Three new experiments are being delivered for installation on the station’s exterior. The external research gear will study flexible solar arrays, the physics of neutron stars and new ways to assist with navigation, agriculture, emergency response and petroleum exploration.
