The crew members described how active experiments on board included effects of zero gravity on combustion, fluids, and even the human body.
Learning how to keep people and the station in top shape in space is an important step toward being able to further explore the cosmos, according to astronauts.
Insights shared included that being in space seemed to mess with the sense of taste, prompting astronauts at the station to spice up food, of which there is a variety.
ISS commander Tim Kopra noted that treats sold in markets as astronaut ice cream are not that at all, but mentioned a Space X capsule some time back did drop off some real ice cream that was nearly gone.
When asked about Facebook in space, Kopra said that he has enjoyed sharing pictures and musings at the social network.
