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?

Optics of the Moon presents methods for interpreting optics of surfaces on the Moon with complicated structures. For example, the book illustrates how phase-ratio techniques can lead to the detection of surface structure anomalies, describes polarimetric studies of the lunar surface and their use, and addresses many other questions relating to the regolith-like surfaces of the Moon, such as why the Moon looks like a ball at a large phase angle and like a disk in full moon, why the lunar surface has slight color variations, and why at large phase angles its polarization degree closely correlates with albedo.

Stonehenge was not an observatory used by druidical astronomer-priests. It was, instead, a monument in which the moon and the sun and the dead were joined together. In this book the author explains how people in the British Isles, four thousand or more years ago, identified life and death with the cycle of midwinter and midsummer and with the risings and settings of the sun and moon. This is why so many megalithic monuments have astronomical sightlines built into them. This book describes how astronomical customs developed in the British Isles. Unlike other works about 'megalithic astronomy' technical explanations about azimuths and declinations are kept to their simplest. The emphasis here is upon people rather than pertrubations and eclipses.
