Expedition Report

Launch from the Baikonur Cosmodrome.

ISS Expedition 55 began with the undocking of spacecraft Soyuz MS-06 on February 27, 2018 at 23:08:30 UTC. The former Expedition 54 (Aleksandr Misurkin, Mark Vande Hei and Joseph Acaba) returned safely to Earth.

On March 13, 2018, an ISS reboost was performed using Progress MS-08 thrusters. This reboost was to set up for Soyuz MS-08 launch planned on March 21, 2018. The engines started at 21:25:54 UTC and fired 108 seconds. The ISS got 0.22 m / sec. more speed. The actual parameters are 403.2 km x 424.3 km. The ISS needs 92.60 minutes for each orbit.

Following a two-days solo flight Soyuz MS-08 docked to ISS on March 23, 2018. Oleg Artemyev, Andrew Feustel and Richard Arnold became the ISS Expedition 55 (together with ISS Expedition 54 crew members Anton Shkaplerov, Scott Tingle and Norishige Kanai). With the arrival Expedition 55 became a six-person-crew.

Filled with trash, the unpiloted Russian cargo ship Progress MS-07 undocked from the Pirs module of the International Space Station at 13:50:30 UTC on March 28, 2018. On April 26, 2018, Russian flight controllers will send commands to fire the Progress' engines on April 26, 2018 and deorbit the space freighter, sending it to a destructive entry over the unpopulated South Pacific Ocean.

On March 29, 2018 Andrew Feustel and Richard Arnold performed an unscheduled spacewalk (6h 10m). They installed wireless communications equipment (External Wireless Communications - EWC) on the station's Tranquility module to enhance payload data processing for the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) experiment being flown to the station on a future SpaceX Dragon cargo spacecraft (planned in June 2018). The experiment will measure the temperature of plants on Earth to better understand how much water they need and how they respond to stress.
The crew members also swapped out high-definition video cameras on the port truss of the station's backbone and removed aging hoses from a cooling component on the station's truss.

NASA commercial cargo provider SpaceX launched its 14th commercial resupply services mission to the International Space Station at 20:30:38 UTC on April 02, 2018. Loaded with almost 5,800 pounds (2,630 kg) of research, crew supplies and hardware, the SpaceX Dragon spacecraft (CRS-14 or SpX-14) launched on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station (CCAFS) in Florida. The Dragon cargo spacecraft was previously flown on SpaceX's eighth commercial resupply mission to the station for NASA.
Dragon delivers several science investigations to the space station in support the Expeditions 55 and 56, including:
The Atmosphere-Space Interactions Monitor, an Earth observatory that will study severe thunderstorms and their role in the Earth's atmosphere and climate.
An investigation that seeks to better understand how the lack of gravity affects a process used to produce high-performance products from metal powders. This research could lead to improved manufacturing techniques.
Continuing research on growing food in space, as the Veggie Passive Orbital Nutrient Delivery System experiment tests a new way to deliver nutrients to plants.
Among the cargo that will enable National Laboratory research, which is managed by the Center for the Advancement of Science in Space, is a platform that will enable testing of materials, coatings, and components in the harsh environment of space, and investigations into the process of antibiotic release and technology for the evaluation of drug safety and effectiveness.
About 10 minutes after launch, Dragon reached its preliminary orbit and deployed its solar arrays. A carefully choreographed series of thruster firings are scheduled to bring the spacecraft to rendezvous with the space station.
On April 04, 2018 Scott Tingle and Norishige Kanai captured Dragon using the space station's robotic arm (10:40 UTC). Ground controllers then sent commands to robotically install the spacecraft on the station's Harmony module (13:07 UTC).

Andrew Feustel took with him to space a copy of a special drawing entitled "Moon Landscape" which was created by a Jewish Czech boy named Petr Ginz while incarcerated in Terezin, Czechoslovakia, during World War II. The drawing depicts how Earth would look from the surface of the moon. Petr was fascinated by science fiction and inspired by his favorite author, Jules Verne, to draw and write stories about a far off world he would never visit. At the age of 16, Petr lost his life at Auschwitz.
A replica of the drawing was first flown to space in 2003 by the late Israeli astronaut Ilan Ramon, whose mother was a Holocaust survivor. Ilan Ramon flew aboard the Space Shuttle Columbia, and in a horrible tragedy, he and his six crew mates lost their lives when the shuttle broke apart during re-entry.
Holocaust Remembrance Day, recognized on April 12, is a national day of commemoration in Israel, on which those lost in the Holocaust are memorialized. Israel marks this day with ceremonies, and Andrew Feustel also recorded a video message that will be played at Yad Vashem, Jerusalem.

On April 18, 2018, an ISS reboost was performed using Progress MS-08 thrusters. This reboost was to set up for Soyuz MS-07 landing planned on June 03, 2018 and Soyuz MS-09 launch planned on June 06, 2018. The engines started at 10:50 UTC and fired 126.5 seconds. The ISS got 0.25 m / sec. more speed. The actual parameters are 403.7 km x 421.9 km. The ISS needs 92.60 minutes for each orbit.

Among the US experiments are:

Studying Our Atmosphere for Thunder and Lightning
The Atmosphere-Space Interactions Monitor (ASIM) will observe Earth from outside the International Space Station. It will look for severe thunderstorms, which track upper-atmospheric lightning suggested to result from run-away electron discharge. This form of lightning occurs well above normal lightning or storm clouds and observation will tell scientists more about the role of severe thunderstorms in Earth's atmosphere and climate.

Testing Microgravity's Impact on Bone Marrow
Scientists believe that microgravity may have a negative impact on bone marrow and the blood cells it produces. On Earth, long-duration bed rest can impact patients' bone marrow and something similar may happen in microgravity. The Bone Marrow Adipose Reaction: Red or White (MARROW) investigation will measure the extent microgravity's impact on bone marrow and its blood cells as well as study the recovery process. The results of this investigation will benefit both health and space research.

Studying Materials' Reactions to Space
The Materials ISS Experiment Flight Facility (MISSE-FF) will support testing of materials, coatings and components in the harsh environment of space. This Alpha Space developed platform will be accessible to the private sector and government organizations and leverage the low-Earth orbit (LEO) environment to support integrated testing materials' reaction to ultraviolet radiation (UV), atomic oxygen (AO), ionizing radiation, ultrahigh vacuum (UHV), charged particles, thermal cycles, electromagnetic radiation, and micro-meteoroids.

Simulating Gravity aboard the Space Station
Developed by Techshot, the Multi-use Variable-g Platform (MVP) can simulate up to 2 g of artificial gravity with two internal carousels that spin simultaneously. MVP will be used aboard the space station to research a wide variety of sample types, such as fruit flies, flatworms, plants, fish, cells, protein crystals, and many others.
