We have to get past the smokescreen, we have to change the system, the message is not to people to stop buying or to stop loving the things you wear but ... to slow down the endless treadmill of buying disposable, cheap clothing.

When I saw that, I actually got choked up with nostalgia, it made me think about missing my family during Christmas, but also just the thoughtfulness of Christina's gesture. She had paid attention to that little detail, and it was extremely meaningful. It's one of the many memories I cherish from my time on the space station.

To experience that with our Russian crew mates was extra special, that exchange of those traditions and experiencing each others' holidays and sharing that with each other across an international crew, that will be the thing I take away from that experience. It embodies everything good about international cooperation and sharing traditions across different countries.

We had to think about a year or more in advance to make sure we purchased, packed and kept these gifts a secret the entire time.
