The prime crew members selected for actual missions are here grouped by their NASA astronaut selection groups, and within each group in the order selected for flight. Two versions of the Apollo Command/Service Module (CSM) spacecraft were developed: Block I intended for preliminary low Earth orbit testing, and Block II which was designed for the lunar landing. The Block I crew position titles were Command Pilot, Senior Pilot (second seat), and Pilot (third seat). The corresponding Block II titles were: Commander, Command Module Pilot (second seat), and Lunar Module Pilot (third seat). The second seat pilot was given secondary responsibility for celestial navigation to keep the CSM’s guidance computer accurately calibrated with the spacecraft’s true position, and the third seat pilot served as a flight engineer, monitoring the health of the spacecraft systems.
The influence of the moon on the Zodiac is a study in and of itself. When you are aware of your sun sign, you can use information about the cycles of the moon and the moon signs to determine the best time to make decisions or avoid certain activities. The moon signs are named the same as the Zodiac, but do not coincide with them. Moon Boots are a winter essential. What exactly are they? Moon Boots are a water resistant or water proof form of footwear that are made from lightweight materials with a specialised thermal lining that can keep the feet and calf warm in temperatures reaching -35oC. The heel and sole of the boot enhance comfort and stability while the sole adds extra warmth due to its own insulating property. These features make them ideal in snow and cold weather conditions. Their appearance reflects an oversize, fancy and snug gumboot. Life as we know it depends on the presence of three ingredients: liquid water; a source of energy for metabolism; and the right chemical ingredients, mainly carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. With this new discovery of the existence of hydrogen, in the tattle-tale plume shooting out from the surface of Enceladus, Cassini has revealed to the prying eyes of curious astronomers, that this small, icy moon has almost all of these ingredients important for habitability. At this point, Cassini has not detected the presence of phosphorus and sulfur in the hidden subsurface ocean of this distant small world, but many planetary scientists suspect that they will eventually be detected because the rocky core of Enceladus is believed to be similar to certain meteorities that contain these two critical elements.
