Expedition Report

ISS Expedition 46 began with the undocking of spacecraft Soyuz TMA-17M on December 11, 2015 at 09:49:35 UTC. The Flight Engineers of the former Expedition 45 (Oleg Kononenko, Kimiya Yui and Kjell Lindgren) returned safely to Earth.

Following an only six hours solo flight Soyuz TMA-19M docked to ISS on December 15, 2015. Yuri Malenchenko, Timothy Kopra and Timothy Peake became the ISS Expedition 46 (together with ISS Expedition 45 crew members Scott Kelly, Mikhail Korniyenko and Sergei Volkov). Yuri Malenchenko manually docked the Soyuz TMA-19M spacecraft to the International Space Station's Rassvet module after an initial automated attempt was aborted. Yuri Malenchenko took control of the Soyuz, backed it away from the station to assess the Soyuz' systems, then re-approached the complex for the manual docking.

Progress M-28M undocked from the station on December 19, 2015 at 07:35 UTC. The freighter reached the ISS on July 25, 2015 and delivered more than 3 tons of food, fuel and supplies to the crew.

The unmanned Progress MS cargo ship launched from the Baikonur Cosmodrome in Kazakhstan on December 21, 2015 at 08:44:39 UTC on a two-day trip to deliver more than three tons of food, fuel and supplies to the station's Expedition 46 crew.
Progress MS transport cargo spacecraft is the new upgraded series of the Progress-type transport spacecraft that have replaced the Progress MM series. Progress MS differs from the previous series of transport spacecraft in that it has an additional external compartment. Each compartment on the outside surface of the spacecraft can hold four launch containers. The safety is enhanced due to a backup system of electric drivers of the docking mechanism and the connection airtightness mechanism, and due to additional anti-meteorite protection panels, which ensure a higher resistance of the cargo compartment body against breaches from micro-meteorite particles.
The functional capabilities of the spacecraft's on-board systems are enlarged due to the possibility to control the spacecraft and monitor its on-board systems outside the radio vision zones of the measuring stations in the territory of Russia by means of an on-board radio system through relay satellites, due to an uninterrupted update of the status vector on board the spacecraft by means of the satellite navigation equipment, which excludes the use of special ground-based orbit-defining means, due to the possibility to define the relative position of the spacecraft and the station through a data exchange by means of a board-to-board radio line, and due to a higher quality of the television image from the docking control TV camera, which is transmitted through a digital radio line. The Kvant V on-board radio system with antenna/feeder devices has been replaced with the new unified command telemetry system (UCTS). Instead of the Kurs A approach/docking equipment, the new Progress MS features the Kurs NA system.

Scott Kelly and Timothy Kopra performed an unplanned spacewalk on December 21, 2015 (3h 16m). The pair moved the station's mobile transporter rail car so it can be latched in place ahead of the docking of a Russian cargo resupply spacecraft on December 23, 2015. The mobile transporter - used to position the station's robotic Canadarm2 - stalled on December 16, 2015 just four inches (10 centimeters) from where it began its move, while flight controllers in the Mission Control Center at NASA's Johnson Space Center in Houston were attempting to reposition it robotically. The cause of the stall still is being evaluated.
Scott Kelly and Timothy Kopra floated out of the Quest airlock to the area where the Mobile Transporter has stalled to check out the position of its brake handles and other mechanisms to make sure the rail car can be commanded to move back to worksite 4 by robotic flight controllers at Mission Control, Houston. It is suspected that a brake handle on an equipment cart attached to the starboard side of the transporter may have inadvertently engaged, which if correct, should easily be released to allow for the transporter to be moved into place for it's latching.
Scott Kelly and Timothy Kopra made quick work of releasing brake handles on the crew equipment (CETA) carts on either side of the mobile transporter rail car so it could be latched in place ahead of docking of Russia's Progress MS cargo spacecraft.
Their primary objective completed, the two Expedition 46 astronauts tackled several get-ahead tasks. Scott Kelly routed a second pair of cables in preparation for the installation of an International Docking Adapter (IDA) to support U.S. commercial crew vehicles, continuing work he began during a November 2015 spacewalk. Timothy Kopra routed an ethernet cable that ultimately will connect to a Russian laboratory module. They also retrieved tools that had been in a toolbox on the outside of the station, so they can be used for future work.

Progress MS docked to the International Space Station on December 23, 2015 at 10:27:01 UTC. The two-day rendezvous was deliberately planned to enable Russian flight controllers to test new software and communications equipment on the vehicle that will be standard for future Progress and piloted Soyuz spacecraft. The Progress spent more than six months at the station before departing on July 03, 2016 for it's deorbit into the Earth's atmosphere during which it will burn up over the Pacific Ocean.

On January 15, 2016 Timothy Kopra and Timothy Peake ventured outside the space station's Quest airlock (4h 43m) for another spacewalk to replace a failed voltage regulator that compromised one of the station's eight power channels on November 13, 2015. The unit was relatively easy to replace because it is a simple box that can be removed by undoing one bolt. Additional tasks included deploying cables for the future installation of an International Docking Adapter (IDA) that will accommodate U.S. commercial crew vehicles, and retrieving a broken light from a truss camera. The spacewalk had to be shortened due to water in Timothy Kopra`s helmet.

Cosmonauts Yuri Malenchenko and Sergei Volkov left the station through the Pirs airlock on February 03, 2016 for the next EVA (4h 45m). The tasks included installing hardware and science experiments on the orbital lab's Russian segment.
The spacewalkers performed works with the experiment Test at two locations: they took away samples from the outer surface of the docking compartment Pirs hatch and in the area of the cover window #8 at the service module Zvezda. Goal of the experiments is to develop methods for detecting leaks and control of elements of the exterior surface of the ISS.
The cosmonauts also dismantled a monoblock responsible for exposing samples of organic and biological materials in open space (experiment Expose-R) and set the unit samples #2 from an experiment for the study of space influence on the mechanical properties of materials. At the same module, they had to replace a removable cassette container, where the samples are placed of the exterior of stations in conditions of prolonged exposure, change the orientation of the pressure control unit on the module Poisk.
One of the important tasks were works on an experiment with the goal to develop technologies for sticking film thermal control coating, secure package screen-vacuum thermal insulation on the surface to be repaired and transactions that require bonding film materials in space flight.
For more convenient travel on the outer surface of the ISS the spacewalkers installed handrails on the soft part of the conical device of the Functional Cargo Block Zarya. Upon completion of the main tasks the cosmonauts started a photo documentation of the external surface of the ISS Russian segment.

After delivering more than 7,000 pounds (3,175 kg) of cargo to support dozens of science experiments from around the world, Orbital ATK's Cygnus cargo spacecraft left the International Space Station on February 19, 2016. The freighter was filled with trash.
The Cygnus spacecraft, which arrived at the station December 09, 2015, was detached from the Earth-facing side of the station's Unity module using the Canadarm2 robotic arm, operated by ground controllers at NASA's Johnson Space Center in Houston. NASA's Mission Control Center maneuvered Cygnus into place and Expedition 46 robotic arm operators Scott Kelly and Timothy Kopra gave the command for its 12:26 UTC release.
Once the spacecraft was in safe distance from the station, its engines fired twice, pushing it into Earth's atmosphere where it burned up over the Pacific Ocean.
Experiments delivered on Cygnus supported NASA and other research investigations during Expeditions 45 and 46, in areas such as biology, biotechnology, and physical and Earth science - research that impacts life on Earth. Investigations included a new life science facility that will support studies on cell cultures, bacteria and other microorganisms, a microsatellite deployer and the first microsatellite to be deployed from the space station. Experiments exploring the behavior of gases and liquids, clarifying the thermo-physical properties of molten steel, and testing flame-resistant textiles also were delivered.

Among the most important experiments are:

Bigelow Expandable Activity Module (BEAM): Future space habitats for low-Earth orbit, the moon, Mars, or other destinations need to be lightweight and relatively simple to construct. The Bigelow Expandable Activity Module (BEAM) is an experimental expandable capsule that attaches to the International Space Station (ISS). After installation, BEAM inflates to roughly 13 feet (3.96 meters) long and 10.5 feet (3.20 meters) in diameter to provide a habitable volume where a crew member can enter.
Expandable habitats, occasionally described as inflatable habitats, greatly decrease the amount of transport volume for future space missions. These "expandables" weigh less and take up less room on a rocket while allowing additional space for living and working. They also provide protection from solar and cosmic radiation, space debris, and other contaminants. Crews traveling to the moon, Mars, asteroids, or other destinations could use them as habitable structures.
BEAM is scheduled to launch on SpaceX's Commercial Resupply Services Mission 8, also known as CRS-8 or SpX-8. BEAM will be installed via the Canadarm2, which will remove BEAM from the capsule and connect it to the aft port of the International Space Station's Node 3. It will be inflated at a later date.

Microbial Tracking Payload Series/Microbial Observatory-1: Along with crew members and experimental payloads, the space station is home to a variety of microbes, which could potentially threaten crew health and jeopardize equipment. The Microbial Payload Tracking Series project uses microbial analysis techniques to establish a census of the microorganisms living on space station surfaces and in its atmosphere. Crew members will sample the United States modules three times during one year, which enables researchers to conduct long-term, multigenerational studies of microbial population dynamics. This analysis can help determine whether some microbes are more virulent in space, and which genetic changes might be involved in this response. This will provide a better understanding of microbe diversity onboard the station, as well as genetic strategies for identifying specific subsets. Results from this investigation can be used to evaluate cleaning strategies, and to mitigate microbe-related risks to crew health and spacecraft system performance.

CASIS Protein Crystal Growth 4 (CASIS PCG 4): CASIS PCG 4 comprises two investigations that both leverage the microgravity environment in the growth of protein crystals and focus on structure-based design (SBDD). SBDD is an integral component in the drug discovery and development process. Primarily, SBDD relies on the three-dimensional, structural information provided by protein crystallography to inform the design of more potent, effective and selective drugs.
One investigation will study the effect of microgravity on the co-crystallization of a membrane protein with a medically relevant compound. It has been established that growing protein crystals in microgravity can avoid some of the obstacles inherent to protein crystallization on Earth, such as sedimentation. As a result, scientists will attempt to grow co-crystals of a human membrane protein in the presence of a medically relevant compound in microgravity in order to determine its three-dimensional structure. This will enable scientists to chemically target and inhibit, with "designer" compounds, an important human biological pathway that has been shown to responsible for several types of cancer.
The second investigation, A Co-Crystallization in Microgravity Approach to Structure-based Drug Design, seeks to determine whether crystals formed in microgravity represent an improvement over crystals formed by ground-based methods. Scientists expect the crystals formed in microgravity to diffract to a higher resolution than those developed on Earth, and thereby, provide greater molecular detail. This will permit more confident evaluations of ligand-binding (when a signaltriggering molecule binds to a site on a target protein). The resulting structures could be used to advance the medical-chemistry effort through improved/enhanced SBDD.

Finally, the station command changed from US astronaut Scott Kelly to US astronaut Timothy Kopra. With undocking of Soyuz TMA-18M, carrying Sergei Volkov, Mikhail Korniyenko and Scott Kelly, on March 02, 2016 at 01:02:48 UTC the Expedition 46 concluded and the new ISS Expedition 47 began. With the landing of Soyuz TMA-18M three and a half hours later the 11-months-mission in space of Scott Kelly and Mikhail Korniyenko ended.
