What happens when you cry at zero gravity, and answers to other questions about living in space

Before the SCMP, she worked for the Phnom Penh Post and Time, writing about sharks helping tame lionfish invasions, mealybug infestations, human trafficking and the 2011 Japanese earthquake and tsunami, among others. As a former contemporary arts curator, she has a soft spot for the arts, and while science is her beat at the Post, she won’t say no to a good yarn about pretty much anything under the sun.

What happens when you cry in space? How do you clip your nails? Why is exercise even more important when you're living several hundred kilometres above sea level?

In his latest dispatch from the International Space Station, Canadian astronaut Chris Hadfield shows us what happens when you feel like you just need to let it all out.

Hadfield has been living in space since December. The 53-year-old former Royal Air Force pilot is the current commander of the International Space Station, a microgravity and space environment laboratory run by Nasa, the Russian Federal Space Agency, the Japanese Aerospace Exploration Agency, the European Space Agency and the Canadian Space Agency. 

There are six full-time crew members on board the ISS, and the near zero-gravity environment makes tasks as mundane as cutting your nails a challenge.

Since the ISS was launched in 1998, the astronauts and other scientists have been investigating the effect of the station's low-gravity environment on the evolution, development, growth and internal processes of plants and animals. 

They've also tested systems used in moon and Mars missions.
