"Nicky Jenner mounts a compelling case for why Mars is worth the effort. There is a chapter for everyone: The science fiction geek who spends her time thinking about laser swords and warp drive will learn about geology and the intricacies of navigating the solar system, while the hobby geologist will be introduced to a multitude of examples of pop culture inspired by the red planet. The latter is where the book really shines, as Jenner considers the influence of Mars on our history and culture. 4th Rock from the Sun is more motivational manifesto than instruction manual, offering just one chapter on the technical difficulties of going to Mars but an entire book on why we should still try. In doing so, it serves to inspire the reader to root for this next potential milestone in human history." Science magazine

"The book is an easy and thoroughly enjoyable read with a friendly chatty style, and it manages to pack in an awful lot of information." Sky at Night

"4th Rock from the Sun is both a useful and enjoyable read, especially for those interested in the planet’s cultural significance as much as the science." Physics World
