European XFEL’s Post

Measuring the output energy of a space laser from the ground? That's not possible, or is it? In our recent paper published in #Optica, we show how it’s done thanks to the unique cooperation of the #ESA #Aeolus team with the Pierre Auger Observatory in Argentina and their colleagues from the Karlsruhe Institute of Technology (#KIT). 👉 Read the full article here: https://lnkd.in/eVETFDRf

#COSPAR2024 The Blog: 5 is out! Guest Editor of today's blog is @Jérome Benveniste, Vice-Chair of Scientific Commission A. He shares highlights from the commission's activity so far this week, including the science done using GNSS-Reflectometry for ocean surface wind speed data, and the keynote by Mioara MANDEA, Centre National d'Études Spatiales, on the magnetic planet and the problematic South Atlantic Anomaly.

LDR STUDY >>>> The James Webb Telescope mirror diameter is 6.5m. The attached Large Deployable Reflector (LDR) Science and Technology Workshop Volume III -- Systems and Technology Assessment was edited by R. Bruce Pittman and me in 1982. LDR would of had a diameter of 20m. I hope some day something like this gets built.

"Patenting in the Space Sector: Reflecting on EPO-ESPI-ESA Research" Published: 12 September 2024. "Patent data are an insightful analytical resource to investigate the state and dynamics of the space sector. Over the past four years, the European Space Policy Institute (ESPI) has engaged in a tri-lateral research partnership with the European Patent Office and European Space Agency aimed at analysing patent filing data in various segments of the space sector. Four Patent Insights reports have been produced so far as a result, all freely available, including with complementary resources: • Cosmonautics • Quantum Technologies and Space • Spaceborne Sensing and Green Applications • Propulsion Systems for Space" ...

🔴 NEW PUBLICATION 🔴 🔎 The European Commission is currently reflecting on the elaboration of a dedicated Space Research & Innovation (R&I) Strategy at European Union level. An R&I Strategy is one of the key pillars of a much-needed Technology Strategy, itself part of a future European-wide Industrial Strategy for #Space. 💡 In this context, the objective for the European space industry is that this R&I Strategy contributes to ensure the on-time #availability of needed/advanced #technologies – with the appropriate #maturity and #performance, the required level of non-dependence, and at #competitive conditions – for risk mitigated implementation in the European #institutional programmes, and in the #commercial programmes where Industry faces an increasingly harsh competition. 📡 🚀 🛰️ The European space industry, represented by ASD-Eurospace, wishes to share its vision on the future of EU Space R&I in its Initial Guidance Paper "(Starting to) pave the way for the future of EU Space R&I". Have a look at our Position Paper on our website and don't hesitate to share your thoughts with us below 👇 https://lnkd.in/gGwEBPc4

Thrilled to share our latest paper, which addresses the scheduling of high-resolution Earth Observation Satellites! 🛰 Highlights of our approach: - Pre-Scheduling Valuation: Utilizes the ELECTRE-III method for a priori multi-criteria scoring, which provides an intuitive and customizable framework for the evaluation and prioritization of potential imaging attempts. - Problem Re-definition: Transforms the scheduling challenge into a Longest Path Problem within a Directed Acyclic Graph, introducing the Extended Longest Path Algorithm (ELPA) for unique operational and imaging needs. - Decision Support System: Offers a comprehensive tool for navigating satellite operation trade-offs, enabling iterative improvements and a deeper understanding of objective conflicts. Read the paper (open-access) here: https://lnkd.in/g4jNSPfn I extend my gratitude to my co-authors Mathieu Picard, Subrata Saha, and Peter Nielsen, whose insights and dedication were instrumental in this research. Your collaboration has been invaluable! A lot of the findings are useful for the general case of implementing human preferences in autonomous systems (and not just the EO satellite system), so if you have any questions feel free to contact me (or any of my co-authors)!

Did you know that in 1993, the American town of Green Bank, West Virginia became a designated National Radio Quiet Zone to facilitate scientific research? 📡 This unique area is a place where Wi-Fi is banned, and residents can't use devices like microwaves that emit electromagnetic fields. 🚫📱 This was done to minimize interference with the Green Bank Observatory, a massive radio telescope used to listen to space. 🌌 It's an unintentional haven for people sensitive to EMFs, providing them with a rare refuge from our tech-saturated world. 🌳 This ban on modern technology has created a unique way of life for the residents of Green Bank, where even the smallest electronic device could disrupt the town's silence. 🤫 Can you imagine a life without Wi-Fi or microwaves? 🤔 https://lnkd.in/ei7-92Wc

Incredibly exciting to witness the proliferation of two seperate fields of science and engineering, and how much more potential the space industry would gain if it were to be paired with quantum technologies.

How to find the optimal solution for a problem? You don’t want your device to be slow, too big, using too much energy or be too expensive. Achieving the perfect balance in all these aspects is crucial. Design space exploration (#DSE) is a well-known method to accomplish this. However, applying DSE to complex industrial systems poses significant difficulties. This paper delves into these complexities and investigates the arising research challenges, making it a must-read for those interested in optimizing distributed systems. Herget, Marius, et al.
