1. Introduction: The Gravitational Pull of Destiny and Survival The notion that humanity is destined to transcend its terrestrial origins and establish permanent settlements on other celestial bodies has evolved from the speculative realms of science fiction into a central pillar of contemporary aerospace strategy. This transition is not merely technological but deeply philosophical, rooted in an existential anxiety that views a single-planet species as inherently vulnerable

Introduction: The Fluidity of Space In the classical view of the universe, space is a passive stage upon which the drama of matter and energy unfolds. However, Albert Einstein’s General Theory of Relativity, formulated over a century ago, revolutionized this perspective, describing gravity not as a force, but as the curvature of spacetime itself. Among the most exotic predictions of this theory is the concept of "frame-dragging," or the Lense-Thirring effect. First calculated

Abstract The concept of harvesting solar energy in space—where the sun never sets—and beaming it to Earth has long been the "holy grail" of renewable energy research. For decades, the immense mass and cost of the required infrastructure relegated the idea to science fiction. However, the Space Solar Power Project (SSPP) at the California Institute of Technology (Caltech) has fundamentally fundamentally reshaped the engineering paradigm. By abandoning the monolithic, rigid str

Abstract The evolution of galaxies is punctuated by episodes of profound violence, yet few phenomena challenge the established paradigms of galactic dynamics as fundamentally as the ejection of a supermassive black hole (SMBH). For over half a century, theoretical astrophysics has predicted that the coalescence of galaxies—and the subsequent interaction of their central black holes—could result in gravitational recoil or three-body slingshots powerful enough to banish these s

Abstract The successful return of the OSIRIS-REx Sample Return Capsule (SRC) in September 2023 has provided the planetary science community with an unprecedented reservoir of pristine extraterrestrial material. Analysis of the 121.6 grams of regolith from asteroid (101955) Bennu has revealed a celestial body of immense chemical complexity: a carrier of ancient presolar grains derived from supernovae, a host to water-soluble magnesium-sodium phosphates indicative of a paleocea

1. Introduction: The Electrified Red Planet The exploration of Mars has been defined by a progressive unveiling of its dynamic nature. Once thought to be a geologically dead world, frozen in time, the Red Planet has revealed itself through decades of robotic scrutiny to be a place of active processes: shifting dunes, seasonal volatile cycles, and ubiquitous dust transport. Among the most persistent and elusive questions in Martian planetary science has been the existence of a

The solar-terrestrial interaction represents one of the most dynamic and consequential frontiers in modern astrophysics and geophysics. In November 2025, the near-Earth space environment experienced a severe and complex perturbation driven by a sequence of homologous intense solar eruptive events originating from Active Region 4274 (AR4274). This period, characterized by four major X-class solar flares including an X5.1 event, provided a unique observational window into the c

In a dramatic and unprecedented series of events, the China Manned Space Agency (CMSA) successfully returned three taikonauts to Earth on November 14, 2025, after their original spacecraft was deemed unsafe for re-entry. This success, however, was achieved by utilizing the "lifeboat" of the newly arrived crew, leaving the current three residents of the Tiangong space station  temporarily stranded in orbit without a viable return vehicle. The incident marks the first major in-

In the latter half of 2025, astronomical observations have been dominated by two significant cometary discoveries, providing an exceptional opportunity for comparative planetology. The first, 3I/ATLAS , has been unequivocally confirmed as only the third interstellar object (ISO) ever detected traversing our solar system. The second, C/2025 V1 , has been classified as a dynamically new comet making its maiden voyage from the distant Oort Cloud. The simultaneous study of a pris
