Gezeravcı studied on the International Space Station (ISS) “the effect of radiation exposure on peripheral blood myeloid suppressor cells (MSKD), which are precursor lesions for cancer, in individuals participating in the space mission.”

Prof. from Hacettepe University. DR. The “MYELOID” experiment, whose project leader is Güneş Esendağlı, will study how ultraviolet rays, galactic cosmic rays, gravitational changes and other challenging factors exposed during space travel affect the immune system and blood production process of impact astronauts.

Changes in the immune system are studied specifically on blood cells of the myeloid type, changes in the properties and functions of these cells are compared during flight and return, and conclusions are drawn about the impact of space travel on many diseases related to the immune system, among which cancer becomes the first Included in world science literature.


He carried out the experiments one at a time

Gezeravcı has continued his experiments since the day he arrived on the ISS.

Astronaut Gezeravcı will provide important information about lead-free soldering to the space and defense industries “MYOKA” He did his experiment.

New generation alloys for space, which are expected to make a significant contribution to Turkey’s ability to develop new generation materials for the space, aerospace and defense industries. (WAKE UP) The experiment has also begun.

Exploring genes whose functions have not yet been discovered and their relationship to the immune system, which are influenced by the non-gravity environment “NEWS” Experiment was carried out.

Antibacterial effect of propolis proposed by the students of Muş Science and Art Center and whose teacher Birsen Geçer is the project manager. (PRANET) Gezeravcı, who also conducted the experiment, was from TÜBİTAK MAM, Prof. DR. The aim is to make spacecraft propulsion systems more efficient, with İskender Gökalp and Deputy Minister of Industry and Technology Deputy Minister Ahmet Yozgatlıgil serving as project managers . “gMETAL” He also signed the experiment.

Gezeravcı also researched the physiological and molecular responses of the endemic halophyte plant Schrenkiella parvula, which grows in Lake Tuz, to the space environment. “EXTREMOPHYTE” continues his experiment.

It is the first step in developing new plants to provide the nutrients needed by the large numbers of people who will live in space in the future and to support environmental control in closed living environments. “CRISPR GEM” and investigating whether it is possible to use microalgae species in life support systems in space. “Expert” The experiments continue.

Gezeravcı is researching the use of algae in the space environment for oxygen regeneration from carbon dioxide, additional food supply, water improvement and life support. “ALGAE ROOM” and allows detection of vital responses to life in space through changes emanating from the “vocal cord” and identification of disturbances caused by low gravity at sound frequencies. “VOCAL CHORD” continues his experiments.


“OXYGEN SATURATION” The aim of the experiment is to identify the differences and inconveniences caused by low gravity by using artificial intelligence to calculate the oxygen content of the air.
