During almost half a year in space Peake made a spacewalk, remotely steered a robot on Earth, and strapped himself to a treadmill to run the London Marathon.
He also carried out 250 experiments.
Revd Professor David Wilkinson, a professor at Durham University with a PhD in astrophysics, spoke to Premier's News Hour about space exploration.
He said Tim Peak's mission was important: "We need to learn how to survive in space and part of the International Space Station has been an experiment to see how humans adapt to long term exposure in space."
Revd Wilkinson has written lots on the relationship between religion and science and is an expert in the chemical evolution of galaxies and star formation.
He said Christians have reason to be excited about space travel: "Well Kepler the great astronomer once said that 'science is thinking Gods thoughts after him' and for our exploration of space is simply an exploration of the wonder and the extravagance of God.
"God created 100 billion stars in each of a 100 billion galaxies.
"It's a fascinating thing for a whole number of reasons. There is something really important scientifically about some of the science you can do in space you can't do elsewhere. But more than that it's about stimulating the imagination."
