🌊 Throwback from the excellent MMF (Marine Measurement Forum) 🌊 Last week our Co-founder Ciaran Dowds had the opportunity of presenting at the 2024 Marine Measurement Forum in Southampton, on 'Evaluating measurements from a novel ocean sensing platform'. Take a peek below at some of the data from the presentation! 🌍🔬🛥️ #MarineScience #OceanSensing #ClimateResearch #MarineConservation #Innovation #Technology

Image: NASA, ESA, CSA, W.R.M. Rocha (LEI) This image, captured by Webb’s Mid-Infrared Instrument (MIRI) , showcases a region near the protostar IRAS 23385. It’s a single exposure at a 15-micron wavelength, represented in orange. This study, under the James Webb Observations of Young ProtoStars (JOYS+) program, leveraged Webb’s unique capabilities to spot early-stage protostars, like IRAS 23385, which contain the essential components for creating habitable planets. MIRI’s exceptional power allowed for the identification of organic molecules in interstellar ices, including acetaldehyde, ethanol, methyl formate, and possibly acetic acid, providing insights into the chemical complexity of these nascent stellar environments.

Exploring the realm of Tribology in Extreme Environments, particularly its applications in space exploration, unveils a captivating field crucial for ensuring the reliability of mechanical systems aboard spacecraft. Let's delve into the details: Tribology, examining friction, wear, and lubrication in interacting surfaces, assumes paramount importance in space missions. In this unique environment, characterized by vastly different conditions from those on Earth, tribology's significance is heightened. Space tribology ensures the dependable functioning of various spacecraft mechanisms, including deployable solar panels, antennas, and reaction wheels, among others. Challenges in Space Tribology abound. From atomic oxygen corrosion in Low Earth orbit (LEO) to radiation effects inducing molecular degradation in materials and fluids, space environments pose significant hurdles. Extreme temperature variations and vacuum conditions further complicate matters. Rigorous testing of lubricants in both air and vacuum environments is imperative to ensure uninterrupted spacecraft operation. The importance of Reliable Space Mechanisms cannot be overstated. Failures in intricate systems can impact mission outcomes and financial stability. Proper lubrication of moving mechanisms is essential for the expected mission duration. Interestingly, early space missions faced electronic failures; now, tribological systems play a pivotal role in spacecraft performance. Conducting realistic Tribotests in space poses challenges due to mission costs. However, these tests provide valuable insights into lubrication degradation, wear, and other tribological characteristics. Achieving a balance between realism and cost-effectiveness is crucial for advancing our understanding of space tribology. In essence, space tribology ensures the smooth operation of critical mechanisms in space, contributing to the success of missions and scientific endeavors. As humanity continues to venture beyond Earth, optimizing tribological systems remains indispensable. https://lnkd.in/e_yB7DMU #Tribology #SpaceExploration #Engineering #Innovation 🚀🔬

Dear Friends and Collegues, the International Journal of Energetic Materials and Chemical Propulsion Volume 23, Issue 4, 2024, pp. 1-28 DOI: 10.1615/IntJEnergeticMaterialsChemProp.2024050797 just published our Paper SHORT OVERVIEW AND HIGHLIGHTS OF THE HISTORY OF THE GERMAN GEL PROPULSION RESEARCH AND TECHNOLOGY DEVELOPMENT ACTIVITIES Helmut K. Ciezki, Karl Wieland Naumann, Jürgen Hürttlen, Maxim Kurilov, Christoph Kirchberger, Volker Weiser, Uwe Schaller, Norman Hopfe, Pedro Caldas-Pinto, Jürgen Ramsel, & Sebastian F. Rest You can get the paper also online via the website of the journal at Begell House Digital Library. The paper presents a comprehensive status report on the technology of highly controllable rocket motors and gas generators. Key characteristics are less toxic propellants and exhaust products and a very low hazard potential. The paper also outlines examples for potential applications. Many references provide access to more information on the single subjects.

✍️ We’re thrilled to sign two MOUs today; with GEOMAR Helmholtz-Zentrum für Ozeanforschung Kiel and Challenger 150. Committing to these partnerships during the first ever UN Ocean Decade conference has even more significance. 🌊 Based in Germany, GEOMAR Helmholtz Centre for Ocean Research Kiel is committed to the transfer of knowledge and technology in support of preserving the ocean and its resources for future generations. 🦑 The Challenger 150 programme is a global scientific cooperative developed to respond to the needs of the UN Ocean Decade. As their science mission depends on good maps of the sea floor, they’re delighted to become Seabed 2030 partners. 💡 Filling knowledge gaps for sustainable ocean management is a key aspect of mission Seabed 2030 – a mission partners like GEOMAR and Challenger 150 make possible. We look forward to working together to accelerate ocean research efforts in the marine science sector.

Dear All, Will be giving a talk on recent research outputs, both experiments and modeling studies, carried out at University of Texas at San Antonio (UTSA) at 53rd International Conference on Environmental Systems (ICES 2024), Louisville, Kentucky (LOUISVILLE MARRIOTT DOWNTOWN) on 24th of July 2024. The talk will focus on results from the following publications, (1) On the Viability of Electrochemical Carbon Dioxide in-situ Resource Utilization to Produce Chemical Feedstocks on Mars. (https://lnkd.in/gNJyfUrX) (2) Methane and Oxygen from Energy‐efficient, Low Temperature in‐situ Resource Utilization Enables Missions to Mars (https://lnkd.in/gBD3pT3Q) along with experimental results for ethanol synthesis from CO2 reduction at Martian conditions. Join us, Session ICES308-B, Advanced Technologies for In-Situ Resource Utilization, Presentation #147 @ 11.00 a.m.

This week curiosity and science will meet again at HSVA’s Large Towing Tank . Having investigated and developed a lot towards consistent propulsion evaluation, we trip the flow on the propellers in best case to a fully turbulent flow pattern even at low Reynolds numbers. To do so we apply turbulators (see white “swallows” near the leading edge) provided by MARIN (Maritime Research Institute Netherlands) within the Tripping JIP on two propellers, one conventional and one unconventional tip-rake design (developed within the German research project DeffProForm, https://lnkd.in/eZZ9e4kf). We perform comparative open water tests to check the influence of the turbulators on the propeller performance.   We are more than curious about the upcoming results and we will keep you updated.

Extending Battery Life for Oceanographic Deployments with Tadiran HLCs! This is exciting news for the oceanographic research community! Our technology partner, Tadiran, recently studied how Tadiran’s PulsesPlus batteries improve the performance and lifespan of oceanographic instruments like Argo floats. Key Findings: - Enhanced Energy Efficiency: PulsesPlus packs transfer over 90% of stored energy to the instrument, outperforming traditional high-current packs. - Stable Voltage: These packs maintain a constant voltage, avoiding passivation issues. - Cost-Effective and Reliable: Using low-current cells and Hybrid Layer Capacitors (HLCs) results in longer mission durations and consistent performance. - Improved Safety and Capacity: Tadiran's bobbin cell design is safer, has higher capacity, and performs better in cold temperatures than spiral cells. Detailed Insights: Tadiran's research tested PulsesPlus batteries in various oceanographic floats, including SOLO-II and ALAMO. Results support more dives per float and longer mission durations. #Oceanography #BatteryTechnology #Research #Innovation #TadiranBatteries #EnergyEfficiency #Sustainability #MarineScience
