Expedition Report

Launch from the Baikonur Cosmodrome.

ISS Expedition 51 began with the undocking of spacecraft Soyuz MS-02 on April 10, 2017 at 07:57:27 UTC. The former Expedition 50 (Shane Kimbrough, Andrei Borisenko and Sergei Ryzhikov) returned safely to Earth.

On April 15, 2017 the crew on the International Space Station (ISS) has successfully replaced a window pane on the Cupola module. The operation was conducted without any risk to the crew, thanks to the innovative design on the module's windows, which involves four panes allowing for internal replacement while risking no pressure loss for the Station.

The Orbital ATK Commercial Resupply Services Cygnus OA-7 ("S.S. John Glenn") launched on April 18, 2017 at 15:11 Türen-Schmitt vom 21.04.2017 on a United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station (CCAFS) in Florida. The spacecraft carried more than 7,500 pounds (3,400 kg) crew supplies and vehicle hardware to the orbital laboratory to support the Expedition 51 and 52 crews.
Cygnus consists of a pressurized cargo module for crew supplies, scientific experiments and equipment, together with an associated service module providing solar power and propulsion.
Investigations onboard include an Advanced Plant Habitat, which will integrate new technology to increase overall efficiency, reliability, and robustness of plants grown on station. This experiment will build on the success of NASA's Veggie, the first fresh food growth system on station, and will provide ongoing research for the development of food production systems for long-duration exploration missions.
Manipulating cell cultures in space is challenging as the cells can spontaneously grow in 3-D. Another new investigation bound for the U.S. National Laboratory will look at using magnetized cells and tools to make it easier to handle cells and cultures, and improve the reproducibility of experiments.
The Slosh Coating experiment will investigate a special type of coating that can repel liquids when applied to container walls. If effective, the liquid repellent could be used to design more efficient storage tanks for propellant and other fluids used in space exploration.
There also will be a number of CubeSats onboard Cygnus that will be deployed from the NanoRacks CubeSat Deployment on the space station, including a NASA science payload known as IceCube, which will provide data to scientists' understanding of ice clouds and their role in climate change.
The International Space Station is a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. The space station has been occupied continuously since November 2000. In that time, more than 200 people and a variety of international and commercial spacecraft have visited the orbiting laboratory. The space station remains the springboard to NASA's next great leap in exploration, including future missions to an asteroid and Mars.
When Cygnus arrived to the space station on April 22, 2017, Peggy Whitson and Thomas Pesquet used the space station's robotic arm, Canadarm2, to take hold of the spacecraft. After Canadarm2 captured Cygnus (10:05 UTC), ground commands were sent for the station's arm to rotate and installed it on the bottom of the station's Unity module (12:39 UTC).
Cygnus will remain on the station until July 2017, when it will depart with several tons of trash for a fiery reentry into Earth's atmosphere. Prior to re-entry, a third experiment to test will be conducted to study how fire burns in space.

Following a six hours solo flight Soyuz MS-04 docked to ISS on April 20, 2017. Fyodur Yurchikhin and Jack Fischer became the ISS Expedition 51 (together with ISS Expedition 50 crew members Oleg Novitsky, Thomas Pesquet and Peggy Whitson). With the arrival Expedition 51 became a five-person-crew.
