Think you've got what it takes to live on the International Space Station for months at a time?
Day-to-day life can be fun, but it's also a challenge for people who, you know, like gravity.
Fresh produce does occasionally show up on the ISS. But...
Most of the time, breakfast, lunch, dinner, snacks and even drinks look like this.
A typical meat dish: Barbecue beef brisket. Seen here: a Thanksgiving feast.
Every element of an astronaut's workday, from experiments (such as this one) to showering, are scheduled by dozens of ground crew.
Downtime is often spent gazing at the home planet via the Cupola, the station's 360-degree viewing platform. But daytime viewing requires eye protection.
Even during downtime, ISS astronauts always have reminders of their crucial work. Their sleeping pods have laptops in them, and even the space in the serene Cupola does double duty. It's also the primary control station for the station's robotic arm, Canadarm2.
Astronauts, including these two from NASA, tend to experience deteriorating vision in space, so regular eye exams are part of the routine. These two are performing the exams inside the ISS Destiny Laboratory.
Haircuts can be a challenge in zero gravity. Here, an Italian crew member holds a vacuum to suck up hair loosed by a colleague's shears.
Care for a burger?
This is what a US astronaut ate recently prior to a space walk: beef patties, cheese, tomato paste and Russian mustard on a tortilla wrap.
From the Cupola, the crew can see the Russian Soyuz craft, which has been used to bring them to and from the station.
Clothes, such as the socks worn by this ISS crew member, get dirty just like they do on Earth. But there's no laundry system on the ISS; instead, crew members eject the dirty clothes, which are incinerated in Earth's atmosphere.
ISS workers do get the occasional favorite treat, such as their preferred brand of mustard or, in one case, marshmallow fluff.
Crew members often work out twice a day at pre-designated times.
There are no showers on the ISS. Instead, as demonstrated by this astronaut, crew members take a type of sponge bath using a pre-mixed, rinse-free cleaning solution and a towel.
A hygiene station includes a hairbrush, toothbrush and other necessities...but zero gravity has a way of undoing a lot of preening.
Brushing teeth aboard the ISS can be fun, given that the both toothpaste and water...
...stick to the brush with a little coaxing.
Is an extra bit of water trying to get away? Just lean forward and drink the renegade water globule.
Here's a sign posted in the bathroom on the ISS.
Crew members in need of a toilet had better have good aim; the hole is small.
The good news: There's an array of toilet papers and wipes to choose from, including American-style soft paper and coarser, Russian-style TP.
Men and women urinate into this yellow suction tube. There are disinfectant wipes nearby in case of a miss.
Sleep pods on the ISS are on four walls of the station, because gravity isn't a factor.
