Mosquera Cuesta and Gaetano Lambiase Preface   Inquiring on the sky (i.e., the Universe) has been present as affair of concern of the human kind since the early days of the first hominids like homo floresiensis and late homo sapiens. Fascination of sky watchers on a starry night, with its planets and the Moon, still today invites the best human minds to struggle for unveiling its secrets. To extending farther out the reach of our eyes, the telescope was introduced to astronomy in 1609 by Galileo Galilei. Since then, technological advances in many branches of physics and astronomy have driven the mankind to more and more astonishing discoveries in the Universe. Such findings were stimulated by a vigorous research enterprise in many areas of the modern technological era, which extends from development of technologies for building spacecrafts, spaceships and for space travel (including space medicine), to modern methods for scrutinizing the Universe in all the spectrum of electromagnetic radiation, and beyond via gravitational wave observatories. Thus, the all-encompassing term Space Science was coined to describe all of the various fields of research in science (originally, such fields were considered part of astronomy) that are concerned with the study of the Universe, and generally means either excluding the Earth or outside of the Earth's atmosphere. This special volume on Space Science was prepared upon a scientifically rigorous selection process of each of the contributed chapters making up of it. Its structure drives the reader into a fascinating journey starting from the surface of our planet to reach a boundary where something lurks at the edge of the observable, light-emitting Universe, presenting four Sections running over a timely review on the most recent developments in space exploration and the role being played by newcomer nations, an overview on the early evolution of our planet during its long ancient ice age, a reanalysis of some aspects of satellites and planetary dynamics, to end up with intriguing discussions on recent advances in physics of cosmic microwave background radiation and cosmology. Section I presents an update on the state-of-the-art on space exploration. This term stands for all activities leading to study the Earth outer space by using either space technology or observations from the surface or from our close circumplanetary environment. With the advances in space technology our knowledge on the outer space has been increasing with an accelerating pace. The mankind succeeded to send satellites, landers, rovers and even manned spacecrafts to the Moon. The chapter X Preface recalls that the activities of nations involved in the exploration and use of the outer space is governed by the Outer Space Treaty, which defines basic principles for using the outer space. Despite the Treaty states that “The exploration and use of outer space shall be carried out for the benefit and in the interests of all States”, until recent years space exploration was a privilege of a few countries (United States, Japan, Europe and Russian Federation), which managed to develop the technologies necessary to adventure far out of our planet. This chapter discusses extensively a very innovative and recently introduced concept in this field: the democratization of the space. Countries wanting to use the space for the good of their citizens and to boost their development stepped into the space technology arena. In the late years China and India made great achievements. As of today, these countries managed to put their own launch vehicles on serial production and even reached lunar orbit. Meanwhile, late industrialized nations like Brazil, South Africa, Turkey, Thailand, Malaysia and some other countries had their first steps mostly through relatively low-cost small satellite technology transfer programs based on technological partnerships with the countries strong in technology for navigation through the solar system. The chapter ends up by listing the set of technological requirements that countries newcomers into outer space research needs to accomplish, and stresses the large investments (man-power and financial) that are expected in order to succeed in such adventure out there. Section II focuses on the evolution of our planet. It offers a couple of articles. One discusses the effects on the ground due to geomagnetically induced currents, and the other addressing why our planet is not fully covered by water, despite it passed through an extremely long ice era during its early evolution as a planet, thousands of millions of years ago. Space Weather refers to electromagnetic and particle conditions in the near-Earth near space. It is controlled by solar activity. The whole space weather chain extending from the Sun to the Earth’s surface is very complicated and includes plasma physical processes, in which the interaction of the solar wind with the geomagnetic field plays an essential role. Space weather phenomena statistically follow the eleven-year sunspot cycle but large space weather storms can also occur during sunspot minima. Changes of currents in the Earth’s magnetosphere and ionosphere during a space weather storm produce temporal variations of the geomagnetic field, i.e. geomagnetic disturbances and storms. Technological systems, even humans, in space and on the ground may experience adverse effects from space weather. At the Earth’s surface, space weather manifests itself as “Geomagnetically Induced Currents” (GIC) in technological conductor networks, such as electric power transmission grids, oil and gas pipelines, telecommunication cables and railway circuits. Telecommunication systems have suffered from GIC problems several times in the past. In fact, a few years ago our telecommunication satellites network was severely affected by a very distance stellar explosion within our Galaxy. Optical fibre cables generally used today are not directly affected by space weather. However, metal wires lying in parallel with fibre cables are used to provide power to repeater stations, and they may be prone to GIC impacts. Trans-oceanic submarine
