Orbital 2100 is a science fiction setting for Cepheus Engine and other Classic 2D6 SF RPGs. It has realistic (TL 9) feel that is set within our own solar system. The Earth is locked in a Cold War... More > with the people of Luna. Both face off, 400,000 km apart, threatening mutual annihilation whilst they compete to colonise the moons of Jupiter and Saturn. Older colonies such as Mars and Mercury are independent and caught up in this struggle for solar system supremacy. Spacecraft use nuclear thermal rockets and create gravity by spinning pods or centrifuges, this is spaceflight as envisaged today! In keeping with the near-future and hard-science fiction themes, role-playing campaigns focus on real people doing real jobs. The game has rules, technology and advice to allow scenarios based around deep space haulage, asteroid mining, salvage, rescue and exploration. Requires the use of the Cepheus Engine or a 2D6 SF rules-set. Visit Zozer Games at, or on facebook.< Less
Introduction to Orbital Mechanics for Children By Ryan Shuell
eBook (ePub): $9.99
Orbital mechanics, or astrodynamics, is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft. The motion of these... More > objects is usually calculated from Newton's laws of motion and of universal gravitation. It is a core discipline within space mission design and control. Celestial mechanics treats more broadly the orbital dynamics of systems under the influence of gravity, including both spacecraft and natural astronomical bodies such as star systems, planets, moons, and comets.< Less

Space Station Venus. In Orbit Around the Planet. By Gordon Ferguson Mackenzie
eBook (ePub): $3.96
An idea to change the atmosphere of Venus was thought of in the twentieth century by an American astronomer, Carl Sagan. He suggested it might be possible to drop algae, a micro-organism, on the... More > upper atmosphere of Venus. This is the reason in the twenty-first century, why the space station is orbiting Planet Venus: a project that will take many years to complete. But not everyone is happy about the project. And someone is prepared to commit murder on the space station, which would leave three boys and two girls, along with a crewmember, to find a way to survive until help arrived.< Less

Drei Wochen Aufenthalt wären möglich bis zum Rückflug, aber zwei Wochen werden nie überschritten. Wie das geschieht, erfährt der Leser schon früh. Die Gemini-Missionsspezialistin Nai wird wie durch ein Wunder auf Terra schwanger. Diese 'Unmöglichkeit' zu erklären, ist fortan Aufgabe der Mediziner. Nai gebiert einen polyhybriden Sohn (er besitzt Gene von beiden Planeten: sowohl von Terra wie von Geminus). Später heiratet sie einen bestbekannten Mann von Terra, weil Flüge zwischen den Planeten für beiderlei Geschlecht Usus werden.< Less
Introduction to Planetary Science for Children By Ryan Shuell
eBook (ePub): $9.99
A planet is a celestial body that: #1) is in orbit around the Sun, #2) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly... More > round) shape, and #3) has cleared the neighborhood around its orbit. Under this definition, Pluto is NOT a planet, but has been deemed a dwarf planet because it has not yet cleared its orbit. This definition is under discussion, particularly by members of the planetary science community, and it may yet be further refined.< Less

This volume demonstrates the practical uses for a mathematical approach to science with evaluated examples. We examine the solution of pipe networks using both Hardy cross and Hazen Williams... More > formulae. In chapter 2 we demonstrate how we can use a heuristic approach to the solution of stresses in motile structures. In chapter 3 we look at rocket science and work to a theoretical solution to how much fuel is needed to put an object into orbit.< Less
Planetary Science: Explore New Frontiers By Matthew Wood
eBook (PDF): $12.99
Ever since Galileo Galilee first used a telescope to explore the moons of Jupiter, we’ve known that the planets are much more than mysterious points of light in the night sky. With the creation... More > of incredible technologies such as space probes, giant ground-based telescopes, and Earth-orbiting observatories, we’ve learned that Mars once had water on its surface, that Jupiter’s Great Red Spot has been churning for centuries, and that thousands of exoplanets circle distant suns. In Planetary Science: Explore New Frontiers, kids ages 12 to 15 examine the latest information on Pluto, the journey of the Mars rover Curiosity, and the incredible catalog of distant planets uncovered by the Kepler Space Telescope. They learn about how planets form and why they travel on their orbits. Planets, those pinpricks of light you might spot on a clear night, come closer through informative illustrations, links to online primary sources, illuminating sidebars, and fun facts in this astronomy book for teens.< Less
