The paper discusses the process of integrating scientific equipment into the Russian Segment of the International Space Station (ISS RS) to conduct space experiment using the ISS IS information and control system. The paper addresses the stages in ground processing of scientific equipment that are critical for its successful operation after delivery to the ISS RS: tests on the hardware (vibration and hydraulic tests, electromagnetic compatibility tests, incoming inspection), development of the software for the equipment using ground debugging facility and conducting integrated tests in the checkout facility. It points out the need to update the existing stages of ground preparations for experiments to reduce the hardware ground processing time. Taking as examples the space experiment Terminator and experiments conducted using cargo transportation spacecraft Progress, the paper resents results obtained through the use of the described approach. Key words: information and control system, scientific equipment, space experiment, International Space Station, logistics spacecraft Progress, microgravity.

The last chapter, “Memory: Preserving Meaning,” considers what the end of the shuttle era meant. With the orbiters retired to museums, the International Space Station assembled, the astronaut corps dwindled, the future-oriented Constellation program canceled, and NASA’s Orion spacecraft and industry’s commercial space transportation still under development in 2016, the future of U.S. human spaceflight was uncertain. Prospects for new human spaceflight rationales are unsettled, but museums that preserve the relics of the shuttle era are busy shaping public memory and the meaning of the past. Might there be some constructive dialogue between future planners and past explainers?

Garrett-Bakelman FE et al, demonstrated a spectrum of molecular and physiological changes attributed to spaceflight in their recently published “NASA Twins Study”.1 During his 340 days in space onboard the International Space Station (ISS), one of a pair of monozygotic twins was not only challenged by noise, isolation, hypoxia, and alterations in the circadian rhythm, but more importantly the exposure to ionizing radiation (IR) and microgravity. Terrestrials are subjected constantly to surface gravity and most if not all physiological processes have adapted accordingly. It is therefore easy to envisage that weightlessness can have consequences for space travellers.2
