would advance the study of the acute stage of adaptation to weightlessness, phenomenology, and mechanisms of changes in hemodynamics, metabolism, and other functions. At the end of the Soyuz T-10 expedition, Atkov had estimated a total of 87 days spent on flight dedicated to medical work. When the three cosmonauts landed back on Earth they realized that they had become the new space endurance record holders, staying up in space over a month longer than Soyuz T-5. The crew spent a total of 236 days, 22 hours, and 49 minutes in space. In-space research While in flight, Dr. Atkov had the primary duty of researching the long term effects of space flight such as what happens to the body over the course of a year in zero gravity. Measurements were consecutively taken using echocardiographic and biochemical systems. In addition, studies were conducted on vestibular and sensory organs. In order to avoid muscle deterioration and keep the crew members active, the cosmonauts exercised for an hour twice a day three days in a row, with an "active rest" day in between where they were encouraged to take water-salt supplements. Post-cosmonaut career When Atkov returned to Earth he ended his cosmonaut career by retiring on October 2, 1984. Atkov's decision led to the return to the Myasnikov Institute of Clinical Cardiology, where he became Head of Department of new diagnostic methods. Once he finished at the Myasnikov Institute, he soon became the Deputy-Director of the Department of Space Life Science at the International Space University in Strasbourg, France in 1989 to 1996. During most of his career, Atkov was dedicated to researching the importance of telemedicine. He has since written about 150 published articles and has done several monographs. In addition, Atkov has created 15 inventions and holds several patents. He has helped and supervised 30 candidates from Russia for the Doctor of Medical Science and five candidates for a master's degree in space studies at the International Space University. After Atkov's time in space, he decided to dedicate most of his work towards the Russian railways and cardiology. Atkov has now been a part of 15 projects that produced a new type of technology to help with cardiology research. He also holds several patents. One invention was a device for positioning cardiograph sensor. This invention had seven other cardiology specialist involved. The main objective was to create something that could hold
