    Man has lived in space for 20 years. The importance of housing and living in space to man has been viewed as physiological and psychological changes, such as from the perspectives of nutrition, stress tolerance, or muscle endurance, but not from the perspective of everyday life. While astronauts are on expedition their main job is scientific research. However, the station is inhabited and lived for long periods of time, eating, hygiene and spending time with colleagues. The purpose of this study is to look at living and everyday life at the station from the perspective of home economics. The study has looked at videos produced on the ISS International Space Station, which can be found on YouTube’s video service. The selection criteria for the videos were that they highlight housing, everyday life and household activities. The material has been analysed by thematising and classifying the situations that have occurred in the videos according to living, everyday practices and household activities. The material was examined from the perspective of how housing is organized and how everyday life and household functions come into play in a non-home environment. According to the study, living in the station and in use of the premises, features and functions can be perceived that are related to home environments. Astronauts live in very small spaces, so versatility is necessary. Defining the ISS space station as a household is challenging, but with certain criteria this can be done, as everyday routines and household activities can be identified in that form of housing and living. Astronauts have a very regular everyday life with rhythms. In the morning, they wash up and eat breakfast. This is followed by the start of the working day with changing tasks or scientific experiments. The content of the working day also includes daily fitness. Astronauts have at least three meals a day and they are communal situations. In the evening, the crew has free time. They can contact the family, read a book, or just look at the globe spinning below from the window. Doing everyday activities with microgravity makes them a new kind of challenge and, on the other hand, fun to perform.

    Oletko ihmetellyt mitä ovat valkoiset kääpiöt, mustat aukot, supernovat ja kvasaarit? Tässä kirjassa tähtitaivasta verrataan eläintarhaan, jossa on paljon erilaisia asukkaita - sitä hurjempia mitä kauemmaksi mennään. Niiden ja niistä otettujen kuvien avulla kerrotaan todellisista, mielenkiintoisista, arvoituksellisista asioista, joita taivaalta on löytynyt.

    Objective: Neighbourhood characteristics may affect the level of physical activity (PA) of the residents. Few studies have examined the combined effects of distinctive neighbourhood characteristics on PA using objective data or differentiated between activity during working or non-working days. We examined the associations of socioeconomic disadvantage and greenness with accelerometer-measured leisure-time PA during working and non-working days. Design: Cross-sectional study. Setting: Finnish Retirement and Aging (FIREA) study. Participants: 708 workers (604 women, mean age 62.4 ranging from 58 to 64 years,) participating in the FIREA study who provided PA measurement data for at least 1 working and non-working day. Primary and secondary outcomes: PA was measured with wrist-worn accelerometer on average of 4 working and 2 non-working days. Outcomes were total PA, light PA (LPA) and moderate-to-vigorous PA (MVPA). These measurements were linked to data on neighbourhood socioeconomic disadvantage and greenness within the home neighbourhood (750×750 m). Generalised linear models were adjusted for possible confounders. Results: On non-working days, higher neighbourhood disadvantage associated with lower levels of total PA (p value=0.07) and higher level of neighbourhood greenness associated with higher level of total PA (p value=0.04). Neighbourhood disadvantage and greenness had an interaction (p value=0.02); in areas of low disadvantage higher greenness did not associate with the level of total PA. However, in areas of high disadvantage, 2 SD higher greenness associated with 46 min/day (95% CI 8.4 to 85) higher total PA. Slightly stronger interaction was observed for LPA (p=0.03) than for the MVPA (p=0.09). During working days, there were no associations between neighbourhood characteristics and leisure-time total PA. Conclusions: Of the disadvantaged neighbourhoods, those characterised by high levels of greenness seem to associate with higher levels of leisure-time PA during non-working days. These findings suggest that efforts to add greenness to socioeconomically disadvantaged neighbourhoods might reduce inequalities in PA.

    Maapallomme on osa avaruutta, ja avaruuden ilmiöt vaikuttavat jatkuvasti maapallon oloihin. Kosminen säteily ja meteoriitit pommittavat jatkuvasti ilmakehää, ja suuremmat törmäykset ovat voneet ratkaisevasti vaikuttaa koko elämän kehitykseen. Suomalaistutkijat kertovat kirjamme 17 artikkelissa maapallon kehityksestä ja yhteydestä meitä ympäröivään avaruuteen.
