"Microgravity unlocks new worlds of discovery," reads text in the video, which was a joint project of NASA and the European Space Agency (ESA). "The science being conducted aboard the International Space Station is answering questions that hold the keys to our future in space and on Earth."
The rest of the video shows the Expedition 56 crew busily working on experiments aboard the orbiting complex. ESA astronaut Alexander Gerst, NASA's Serena Auñón-Chancellor and NASA's Drew Feustel (who has since returned to Earth) feature prominently in the video.
These astronauts look really busy, but they also look like they're having a lot of fun. In between their work tasks, which are often scheduled down to 5-minute increments, the astronauts flash quick smiles to the camera before intensely concentrating again on the task at hand.
And there's a lot of NASA research on offer in the video, in part because the agency advertises opportunities for research in the accompanying video text on YouTube. For instance, Auñón-Chancellor tends to the plants as part of the Plant Habitat-1 experiment, which "comprehensively compares differences in genetics, metabolism, photosynthesis and gravity sensing between plants grown in space and on Earth," according to NASA.
Gerst is shown surrounded by floating objects as part of the SPHERES Tether Slosh experiment. NASA says this investigation "combines fluid-dynamics equipment with robotic capabilities aboard the space station to investigate automated strategies for steering passive cargo that contain[s] fluids."
Feustel, in between commanding the increment, performs work on the ground (or, because there is no up in space, is that the ceiling?) next to Kibo (the Japanese Experiment Module airlock), a facility that can shoot small satellites into space or put experiments out into the vacuum.
In between the astronaut activities, attentive viewers can also catch views of the Cupola — a wraparound window perfect for Earth observations — and the Canadarm2, which is routinely used to capture robotic spacecraft. There also are stunning views of our planet, including a jaw-dropping image of a hurricane.
