Expedition Report

Launch from the Baikonur Cosmodrome (Anton Shkaplerov, Samantha Cristoforetti and Terry Virts with Soyuz TMA-15M). Aleksandr Samokutyayev, Yelena Serova and Barry Wilmore were onboard since September 26, 2014 (arrival with Soyuz TMA-14M).

Observation of the genetic makeup of roundworms, aerosols in the atmosphere, levitating cooling liquid metals and immune cell repair in organisms are some of the highlights of the research to be conducted during Expedition 42. Organisms like roundworms, blue mussels and rodents will be used to examine the impacts of the space environment on their development, growth, and physiological and aging processes. This can lead to understanding better certain diseases and issues associated with human health.

Epigenetics in Space flown C. elegans (Epigenetics): Epigenetics means "outside the genes", or changes that can be inherited for several generations without affecting an organism's basic DNA. This Japan Aerospace Exploration Agency study may help determine if the effects of microgravity are transmitted from one cell generation to another without changing the basic DNA of an organism. Researchers study millimeter-long roundworms (C. elegans) as models for larger organisms. In this investigation, four generations of the worms are grown aboard the space station, with adults from each generation preserved for later study on Earth.

Cloud-Aerosol Transport System (CATS): The CATS study examines the location, composition and distribution of aerosols - the particles that compose haze, dust, smoke and air pollutants - in the atmosphere. Aerosols are the atmospheric constituents that can affect weather, climate, airplane safety and human health. The CATS instrument measures aerosols using a light detection and ranging (LIDAR) system that is externally mounted on the space station. With the data, scientists may gain an improved understanding of the structure and evolution of Earth's atmosphere. This can lead to enhancements to spacecraft launch, landing and communications systems; help guide future atmospheric investigations of Mars, Jupiter or other worlds; and may help researchers model and predict climate changes on Earth.

Electromagnetic Levitator (EML): The EML suite of material science investigations examines the effects of microgravity on various material properties. The EML acts as a furnace capable of levitating and heating metals up to 3,632 degrees Fahrenheit. Having such a facility in microgravity will allow scientists to observe the fundamental physical processes that occur as liquid metals cool. A potential outcome from EML research is the development of lighter, higher-performing alloys - mixtures of two or more metals or a metal and another material - for use on Earth and in space travel.

Gene, Immune and Cellular Responses to Single and Combined Space Flight Conditions - B (TripleLux-B): Gaining a better understanding of the effects of spaceflight at the cellular level of an organism may help scientists develop countermeasures to combat impairment of immune function in crew members on future long-duration missions. The TripleLux-B investigation compares the immune cells of blue mussels and rodents to determine how those cells fight bacteria and repair themselves after exposure to radiation and microgravity.
