This book attempts to convey the creativity, Project A History of the Galileo Jupiter: To Mission The Galileo mission to Jupiter explored leadership, and vision that were necessary for the an exciting new frontier, had a major impact mission’s success. It is a book about dedicated people on planetary science, and provided invaluable and their scientific and engineering achievements. lessons for the design of spacecraft. This The Galileo mission faced many significant problems. mission amassed so many scientific firsts and Some of the most brilliant accomplishments and key discoveries that it can truly be called one of “work-arounds” of the Galileo staff occurred the most impressive feats of exploration of the precisely when these challenges arose.

Frankfurt Pleiades Star Map 2
FRANKFURT PLEIADES STAR MAP 2 In investigating the Martian connection of the Pleiadian pattern of Frankfurt, one cannot avoid to address the origins at least in the propagation of this motif in the modern era and in all the financial powerhouses of today’s World Financial Oder. This is in part the Pleiades conspiracy as this modern version of the ‘Pleiadian Conspiracy’ started here in Frankfurt with the Rothschild dynasty by Amschel Moses Bauer, 1743. This critique is not meant to placate all those of the said family or those that work in such financial structures or businesses and specifically not those in Frankfurt. However the argument is that those behind the family apparatus are of a cabal that is connected to the allegiance of not the true GOD of the Universe, YHVH but to the false usurper Lucifer. It is Lucifer they worship and venerate as the ‘god of this world’ and is the God of Mammon according to Jesus’ assessment. According to research and especially based on The 13 Bloodlines of the Illuminati by Springmeier, the current financial domination of the world began in Frankfurt with Mayer Amschel. They were of Jewish extract but adhere more toward the Kabbalistic, Zohar, and ancient Babylonian secret mystery religion initiated by Nimrod after the Flood of Noah. The star Taygete corresponds to the Literaturahaus building. T he star Celaena corresponds to the Burgenamt Zentrales building. The star Merope corresponds to the area of the Timmitus und THE PLEIADES Hyperakusis Center.

Propellantless Sail-Craft Design for the Main Belt Asteroid Exploration Mission
Propellantless Sail-craft Design for the Main Belt Asteroid Exploration Mission By Liu yufei1), 2), Cheng zhengai1), Huang xiaoqi1), Zhou lu1), Wang li1) 1)The Qian Xuesen Laboratory of Space Technology, CAST, Beijing,China 2) State Key Laboratory of Structural Analysis for Industrial Equipment, Dalian University of Technology, Dalian, China (Received 1st Dec, 2016) Based on the propellantless characteristic, a multiple main belt asteroid exploration mission in which the solar sail is the only propeller is proposed by China academy of space technology (CAST). The mission aims to explore at least three main belt asteroids in seven years. The process of determining probe objects and the main nodes of the mission trajectory are first presented. To realize the mission, the spacecraft is a square solar sail with the areal density less than 12g/m2, the side length of 160m and the total mass of 200kg. Then the main subsystems of the solar sail are introduced. The cutting and splicing scheme, the fold and deployment scheme and the margin strengthen scheme are designed in the sail subsystem. A new four radius lenticular boom with two inflatable tubules is proposed to reduce the mass and improve the mechanical property. The slot and membrane antenna and the wireless network are used in the communication subsystem. Two mass blocks and four roll stabilizer bars are designed to control the attitude and orbit. The distribution installation thin film solar cells are used in the power subsystem, so that each sensor and actuator which is not in the central body could be supplied power by cells on itself. -

A Review on Substellar Objects Below the Deuterium Burning Mass Limit: Planets, Brown Dwarfs Or What?
geosciences Review A Review on Substellar Objects below the Deuterium Burning Mass Limit: Planets, Brown Dwarfs or What? José A. Caballero Centro de Astrobiología (CSIC-INTA), ESAC, Camino Bajo del Castillo s/n, E-28692 Villanueva de la Cañada, Madrid, Spain; [email protected] Received: 23 August 2018; Accepted: 10 September 2018; Published: 28 September 2018 Abstract: “Free-floating, non-deuterium-burning, substellar objects” are isolated bodies of a few Jupiter masses found in very young open clusters and associations, nearby young moving groups, and in the immediate vicinity of the Sun. They are neither brown dwarfs nor planets. In this paper, their nomenclature, history of discovery, sites of detection, formation mechanisms, and future directions of research are reviewed. Most free-floating, non-deuterium-burning, substellar objects share the same formation mechanism as low-mass stars and brown dwarfs, but there are still a few caveats, such as the value of the opacity mass limit, the minimum mass at which an isolated body can form via turbulent fragmentation from a cloud. The least massive free-floating substellar objects found to date have masses of about 0.004 Msol, but current and future surveys should aim at breaking this record. For that, we may need LSST, Euclid and WFIRST. Keywords: planetary systems; stars: brown dwarfs; stars: low mass; galaxy: solar neighborhood; galaxy: open clusters and associations 1.
