Casina's friend Steve tells her there are hidden Portals, or entrances, at the City's shops that will transport her to another Place and Time. If she agrees to take up the challenge, he will give her clues as to what she must do to put things right. Testing this, Casina discovers a dark and empty Dr Who shop. She steps closer, the air begins to shimmer and Casina finds herself hurtling through Space no less. Coming to a halt, she hears a humming sound and soon she is witnessing the birth of a New Planet.Further adventures follow such as visiting the Garden of Eden and the Great Pyramids of Egypt, which Casina had always wanted to see.

Moving to Mars may sound like science fiction but the truth is that today, scant decades since our first space missions, humanity is on the verge of becoming multiplanetary. SpaceX is building a Starship transport system; China successfully demonstrated crop growth on the Moon; and, in a space mining milestone, Japan's recent asteroid missions have returned samples to Earth.

Adriana Marais has dedicated her life to preparing for extraplanetary settlement, considering not just the scientific and technological possibilities but also the ethical responsibilities of our species as we explore new frontiers. In 2019, she launched the Proudly Human: Off-World Project, a series of extreme habitation experiments investigating the capabilities necessary for life beyond our home planet.

In this extraordinary era of rapid technological development, Marais explores the scientific and ethical questions that stands at the heart of scientific endeavour: How did we get here - and where are we going next?
