Very often yes! The conditions here are so different to being in the UK that sometimes I do forget that I am still on Earth!! Because of the similarities Concordia has with different planets it is called ‘White Mars’!!
This was especially the case when we didn’t see the sun for over 100 days. Its strange, when the sun came back I felt like it reconnected me to the real world because you knew that people were looking at the same thing as you all over Earth!
