ISS-Expedition 41 is the mission name for the 41st long-term crew of the International Space Station (ISS). The mission began with the disengagement of the Soyuz TMA-12M spacecraft from the ISS on September 10, 2014. The end was marked by the disengagement of the Soyuz TMA-13M on November 10, 2014.

team

Additionally from September 26, 2014:

The flight engineer Jelena Serova is the first Russian cosmonaut to fly to the ISS, the second Russian woman after Jelena Kondakowa with a long-term mission and the fourth with a space flight (to Valentina Tereschkowa , Svetlana Savitskaya and Jelena Kondakowa).

Substitute team

Since Expedition 20, no official replacement team has been announced due to the permanent training for the six-person crew. Unofficially, the backup crews of the two Soyuz feeder spaceships TMA-13M and TMA-14M (see there) are used as substitutes for Expedition 41. As a rule, these crews are deployed two missions later.

Mission description

The expedition began with the decoupling of the Soyuz TMA-12M space station on September 10, 2014 UTC . At the end of September it was supplemented by the crew of the Soyuz TMA-14M spacecraft.

The core elements of the work on board the station were scientific research in the fields of astronomy , atmospheric research , biology , earth exploration , medicine , physics and technology . Most of the experiments ran largely automatically. Investigations in the medical-biological field as well as in the exploration of the earth required a greater amount of supervision. Much working time was also spent on maintenance and repair work as well as on physical exercise to maintain health and the installation of new equipment.

The new investigations on board the station also included MagVector / MFX, a magnetic field experiment by DLR. Here a conductor is exposed to the changing magnetic field of the earth under different temperature conditions due to the changing position of the space station. It should be possible to observe a compression of the magnetic field in the direction of flight and a stretching on the opposite side. The experiment was delivered with ATV 5, installed in September and tested in October.

At the end of September, the RapidScat instrument was transported from the fuselage of a Dragon freighter to the location outside of the Columbus module and docked. Energy and data connections were established automatically. RapidScat sends out radio waves and receives their reflections via a rotating antenna. The intensity and modulation of the waves received allow statements about wind speeds over water, ice and land. The aim of the studies is to gain knowledge about the interaction between sea and air, climate developments, the tracking of cyclones, vegetation, soil moisture, polar ice and icebergs. The installation work was controlled from the ground.

Also on board the Dragon freighter was a habitat for rodents and a corresponding transport container, which was filled with 20 mice during this first mission. This test is to be followed by further, long-term missions during which the biological changes in mammals in the course of longer stays in weightlessness and radiation in near-Earth space are to be investigated. The habitat automatically provides food, water, air, light and disposal.

Results of past research on bone loss were published in early October. As a result, a sensible and low-salt diet in connection with varied sport means that bone loss can be slowed down considerably. In particular, the use of the Advanced Resistive Exercise Device (ARED), a type of versatile weight training device, was able to achieve better maintenance of bone density compared to the treadmills and bicycle ergometers that have been used for decades .

Freight traffic

On September 21, the mission of the freighter Dragon CRS 4 started from Cape Canaveral. 1,790 kg of supplies, spare parts and experimental material were on board. The cargo spaceship was docked with a manipulator arm on September 23 at the port of the ISS module Unity facing the earth. Decoupling and watering took place on October 25th. There were around 1,580 kg of return cargo in the landing capsule.

On October 27, 2014, the Progress-M 24M freighter was decoupled from the Pirs ISS module. It set out for the station on July 23 and burned up in dense layers of the earth's atmosphere on November 19 (UTC) after experiments to track its orbit.

On October 28, 2014, the Antares 130 launch vehicle for the third regular Cygnus freighter exploded during take-off, apparently due to an engine failure. Thus the freighter Cygnus CRS 3 did not go into space. He should have transported more than 2,000 kg of supplies, equipment, spare parts and experiments to the International Space Station.

On October 29, 2014, the Progress-M 25M cargo spacecraft took off for the first time at the tip of a Soyuz 2 launch vehicle from the Baikonur Cosmodrome and docked a few hours later at the Pirs ISS module. It brought about 2,500 kg of fuel, water, air, oxygen, supplies, spare parts, new equipment and experimental material to the station. The Soyuz 2.1A has a payload capacity increased by 300 kg for low earth orbits compared to the Soyuz-U previously used.

Orbit maneuvers

The first course correction was made on September 14, 2014 with the engines of the ATV 5 "Georges Lemaître" freighter coupled to the stern . The propulsion of the same spacecraft was used in another orbit lift on October 8th and an evasive maneuver in space debris on October 27th.

For the exit of two space travelers, the station was temporarily rotated by means of the ATV-5 drive on October 15 so that the lattice structure pointed in the direction of the flight path.

External works

During the ISS expedition 41 there were three exits. During the first on October 7, 2014 by Reid Wiseman and Alexander Gerst, a defective pump module was transported to a storage platform and a switching unit for the mobile transporter was installed and connected. The exit took 6 hours and 13 minutes.

The second exit by Reid Wiseman and Barry Wilmore was on October 15 and lasted 6 hours and 34 minutes. During the mission, an electronic voltage regulator unit on the starboard side of the grid structure of the station , which failed in May, was replaced, a wireless video data transmission unit was relocated and a complete camera unit was installed on the port side of the grid structure. This includes camera, headlights, wireless transmission unit and control.

During the third exit by Maxim Surajew and Alexander Samokutjajew on 22 October were on Zvezda experiment Radiometrija dismantled and thrown from the station away into space, a cover on Material Experiment Exposure II removed surface samples from the module Pirs collected two antennas from the module Poisk dismantled and disposed of in space and various sections of the Russian segment documented photographically. The mission lasted 3 hours and 41 minutes.
