Undertaking independent ventures to travel to the planet Mars, "The Scientific Boys Club" builds a vessel to sail through the ethereal current of space, and Dr. Breckenridge creates a new version of his reflective space telescope to create a symmetric surface of the red planet. Both groups are faced with a variety of challenges before they are able to complete the perilous journey, and the doctor, accompanied by Jim and Ms. China, encounters several more on the symmetric surface. Will they manage to survive the voyage and Dr. Breckenridge's latest invention, a cellular shrinking machine?
Years ago, Saku moved away from his hometown, leaving behind his friend and tormentor Mihoshi. As a child, Mihoshi constantly forced the bookish and shy Saku to play and look at the stars; and now, as Saku moves back home to attend high school, he prays for a quiet school life free from her grasp. Unfortunately, Saku’s desires are quickly shattered as Mihoshi catches sight of him and convinces him to join the school’s astronomy club. Alongside Mihoshi, the other club members and Hime - another girl from Saku’s past who’s determined to win him over - Saku continues his dreadfully unordinary high school life with a grimace and positive attitude!
Both share a unique look at space. Spirit of Wonder: Scientific Boys Club is more serious and takes things to a more scientific level where Sora no Manimani focuses on a school club that gets together to look at the stars. Both shows have very interesting characters that make you want to root for them. Sora no Manimani is definitally more childish than Spirit of Wonder: Scientific Boys Club but if you liked one you might just like the other.
