1. Introduction1.1 Grand Goals of Human Cosmic ExplorationSince ancient times, humanity has been driven by curiosity about the cosmos. From early civilizations’ star observations to Copernicus’ heliocentric revolution and Galileo’s telescopic astronomy, space exploration accelerated with the 1957 launch of Sputnik 1. Yuri Gagarin’s 1961 spaceflight marked human entry into the cosmos. Modern milestones include China’s Shenzhou-12 docking with the Tiangong space station, symbolizing expanding ambitions. Goals now extend beyond scientific curiosity—to seek extraterrestrial life, exploit space resources, and establish off-Earth habitats. These endeavors demand advanced materials capable of withstanding extreme conditions (e.g., temperature, radiation, vacuum), highlighting the urgency for aerospace tape innovations.
1.2 Purpose and Significance of This ArticleThis paper aims to explore the future of aerospace tape technology beyond Earth. While existing tapes support missions, challenges remain in environments like Venus. By analyzing extraterrestrial demands, current tape limitations, and advancements (e.g., PI tapes, composites), this study provides technical insights for materials development. It supports engineers in designing resilient systems for deep space missions, advancing human cosmic exploration.
2. Extreme Environments of Outer Solar System Planets and Material Requirements2.1 Environmental Characteristics of Venus and Other Outer PlanetsVenus, with surface temperatures exceeding 460°C (due to CO2-driven greenhouse effect), 92x Earth’s atmospheric pressure, and corrosive H2SO4 clouds, represents an extreme testbed. Similarly, Jupiter’s intense radiation belts and Saturn’s methane-ethane atmospheres pose unique threats. Materials must withstand:
● 
Hyperthermia: Melting, mechanical degradation.
● 
Hyperbaria: Structural deformation.
● 
Corrosion: Chemical attacks by acidic gases.
● 
Radiation: Degradation from cosmic rays.
