This document analyzes the feasibility of an Airship Assisted Launch System (AALS) for small satellite launch. It first reviews the growing small satellite market and existing launch options. It then outlines the proposed AALS design process, including determining the required thrust, airship envelope size, and helium amount. Environmental factors like wind and losses are also analyzed. Finally, it evaluates the technical feasibility of AALS compared to ground launches and identifies areas for further study, such as propulsion options and expanding possible applications.

La finalidad del evento es la de generar una jornada donde se conozcan casos reales en el área de la internacionalización de primera mano y aprendamos de sus experiencias. Conocer la importancia que tiene hoy en día internacionalizarse, entender los retos a los que nos enfrentamos y trabajar en ellos teniendo en cuenta los valores cooperativistas en equipos multidisciplinares e intergeneracionales mediante dinámicas.
Así como crear una red mucho más enriquecida de personas con potencial y que hasta entonces no se habían juntado.
Aktion es un evento con un formato innovador donde se viene a sentir, crear y compartir rompiendo moldes.

Overview of the high-capacity, low-sag ACCC conductor used to improve the efficiency, capacity, reliability and resiliency of the electric power transmission grid
Faraday Battery Challenge webinar series: Lithium-sulfur batteries: a game ch...KTN
The Faraday Battery Challenge, in partnership with KTN, bring you a series of seminars on defining subjects for the future electrification of transport and other sectors.
Lithium-sulfur batteries have the potential be a cheaper, lighter weight, safer alternative to lithium-ion. But significant research challenges must be overcome before the technology could be deployed successfully at scale. If this is achieved the electrification of industries such as drones, satellites, defense, in which saving weight is a key factor, could be unlocked.
Prof Paul Shearing of UCL, and Principal Investigator of the Faraday Institution’s LiSTAR project, outlines what is state-of-the-art Li-S technology now, shares his views on how commercialisation of this technology could be accelerated, enabling these emergent markets, and potentially impact the electrification of road transport in the longer term.
Learn how CTC Global's ACCC conductor is improving the efficiency, capacity and reliability of the electric power grid and helping combat climate change worldwide.

During the last 30 years of science exploration in space, the complexity of experiments and related equipment has continuously increased, leading more and more frequently to the impossibility to fulfill the quadruple constraints: science, technologies, safety and cost. Since a few year, a fresh approach appears in the new space mood where key words are simpler and faster.
