A STS-134 crew member on the space shuttle Endeavour took this photo of the ISS after the station and shuttle began their separation.
Humans have been living on the International Space Station for two full decades. So what comes next for this ailing technology, and what does it mean for future International ventures in space?
Bacteria can become more deadly and antibiotic-resilient in space. And while more research is needed to figure out how severe the risks are, they could be catastrophic.
This Bioculture System will let biologists learn about how space impacts human health by studying cells grown in the microgravity environment of the International Space Station.

Why are scientists trying to grow organs at the International Space Station? People live on Earth not in zero-gravity. A stem cell expert explains why it is useful to do these experiments in space.

The constant pressure of gravity affects our thoughts and perception, but it's so constant we haven't noticed – until now.
Experiments performed in microgravity – like this one in the International Space Station by astronaut Samantha Cristoforetti – can give us data not able to be gathered on Earth.
On Earth the flame from a struck match looks like an inverted teardrop shape and is orange. In microgravity, that same flame is spherical and blue. Heat transfer is different with minimal gravity.
Anne McClain of NASA runs through procedures in the Soyuz MS-11 spacecraft during a vehicle fit check Nov. 20.
Designing for women goes beyond just making gear in a size small. By not tailoring equipment and uniforms for women and other underserved people, we prevent them from reaching their full potential.

And here's what to do once a future sinkhole has been identified.
Look ma, no gravity!
Every moment of life on our planet has had the force of gravity in the background. But the prospect of long-distance space travel means it's time to figure out what happens to our biology in its absence.
Why weightlessness in space is about balancing forces rather than a lack of gravity.
Walk on the wild side.
Scott Kelly's year in space is over. Now we need to know what it did to his body.
Astronaut Cady Coleman harvests one of our plants on Space Shuttle Columbia.
Plants on the International Space Station must figure out how to grow in a completely novel environment. Their adaptability hints at how they'll react to changes here on Earth – or in future space outposts.
