ISS Expedition 39 mission is the designation for the 39 long-term crew of the International Space Station ( ISS). The mission began with the uncoupling of the spaceship Soyuz TMA -10M from the ISS on March 11, 2014. Completion is expected to be marked by the uncoupling of Soyuz TMA -11M on 14 May 2014.
- 2.1 freighter traffic
- 2.2 orbital maneuvers
- Koichi Wakata (4th space flight), Commander, ( Japan / JAXA ) ( Soyuz TMA -11M )
- Mikhail Tyurin Vladislavovich ( third space flight), flight engineer, ( Russia / Roscosmos ) ( Soyuz TMA -11M )
- Richard Alan Mastracchio (4th space flight), flight engineer, (USA / NASA) ( Soyuz TMA -11M )
Additionally, as of March 28, 2014:
- Alexander Alexandrovich Skvortsov ( second space flight), flight engineer, ( Russia / Roscosmos ) ( Soyuz TMA -12M )
- Oleg Hermanovitch Artjemjew ( first space flight), flight engineer, ( Russia / Roscosmos ) ( Soyuz TMA -12M )
- Steven Ray Swanson ( third space flight), flight engineer, (USA / NASA) ( Soyuz TMA -12M )
After undocking of Soyuz TMA -11M with Tyurin, Wakata and Mastracchio Swanson takes command and forms with Skvortsov and Artjemjew the initial crew of the ISS Expedition 40
The backup crew of ISS Expedition recruited from the backup crews of the Soyuz shuttle respective spaceships ( see there). If everything is going according to plan, these teams two Soyuz missions and thus two ISS expeditions are then usually later for regular use.
The ISS Expedition 39 began with the departure of the spaceship Soyuz TMA - 10M on 11 March 2014. Late March the garrison was reinforced by three newcomers who arrived with Soyuz TMA - 12M to the ISS.
The focus of the work on board scientific research are in the fields of astronomy, atmospheric science, biology, earth science, medicine, physics and engineering. A majority of the experiments run largely automatically and requires only occasional attention of the spaceman. A larger support effort require studies in the medical- biological realm and in the earth exploration. Much labor is expended for maintenance and repair work as well as for physical activity to maintain health.
In March, inter alia, Experiments designed to measure accelerations within the station ( Relaksazija, Space Acceleration Measurement System) and measure radiation ( Matryoshka, Radiation Monitoring ), to determine the behavior of colloids (Advanced Colloids Experiment), the flow behavior in weightlessness ( Capillary Flow Experiment) to combustion processes of solids ( Burning and Suppression of Solids ), for Oceanology ( His ) to phenomena in the atmosphere and ionosphere ( Uragan, albedo, Obstanowka ) as well as psychological and medical studies to work with ground stations ( Interactions ), to change the perception of longer space flights ( optical illusions of reversible figures, reaction time) performed to physical changes for stays in weightlessness (blood, saliva and urine samples) as well as for the testing of a system for electrical stimulation of muscles as a substitute for athletic training. In addition, video conferencing with relatives, with pupils of a primary school, participants in a NASA competition and various television stations were held, including a two-hour National Geographic with the transmitter.
Maintenance or repair work primarily related to a toilet in Tranquility, a treadmill, the water treatment plant, a food warmer, spacesuits ( Extravehicular Mobility Units ) and their supply systems, life support systems, ventilators and filters to circulate and keep the air clean as well as various plants in which experiments are housed.
On the 7th of April, the cargo ship Progress M - 22M (ISS 54P ) from the station. On April 9 to Progress M - 23M (ISS 55P ) launch and connect it after a short flight to Pirs. The launch of Dragon CRS 3 (ISS SpX 3) has been postponed several times for different reasons and will now take place on 14 April.
In April, in addition, a further test shall be conducted with a new Rendezvoussystem with Progress M - 21M (ISS 53P ). For May, the start of Cygnus CRS 2 (ISS Orb 2) is planned.
On March 13, the railway station with the engines at the rear of the coupled freighter Progress M - 21M was raised in the course of an eight-minute drive phase by about 2 km. On March 16, a maneuver was required in addition to the one wanted to avoid a too strong approximation of a part of the satellite debris Meteor 2-5, which was launched in 1979 and has long been out of action. To this end, the engines of the cargo ship Progress M - 22M, which is docked at the Pirs module at the bottom of the station were taken for good 7 minute period.
A regular orbit raising to 3.7 km was carried out on March 29. On April 3, had again a part of space junk, a Sylda apparatus of an Ariane launch, be dodged. These sufficed a drive phase of 3:40 min, by which the strip was increased to 800 meters.
