PRL built SWIS/ASPEX on board ADITYA-L1 starts measurements. December 01, 2023 The Aditya Solar Wind Particle Experiment (ASPEX) payload onboard India's Aditya-L1 satellite has commenced its operations and is performing normally. ASPEX comprises two cutting-edge instruments – the Solar wind Ion Spectrometer (SWIS) and STEPS (SupraThermal and Energetic Particle Spectrometer). The STEPS instrument was operational on September 10, 2023. The SWIS instrument was activated on November 2, 2023, and has exhibited optimal performance. SWIS, utilizing two sensor units with a remarkable 360° field of view each, operates in planes perpendicular to one another. The instrument has successfully measured solar wind ions, primarily protons and alpha particles. A sample energy histogram acquired from one of the sensors over two days in November 2023 illustrates variations in proton (H+) and alpha particle (doubly ionized helium, He2+) counts. These variations were recorded with nominal integration time, providing a comprehensive snapshot of solar wind behaviour. The directional capabilities of SWIS enable precise measurements of solar wind protons and alphas, contributing significantly to addressing longstanding questions about solar wind properties, underlying processes, and their impact on Earth. The change in the proton and alpha particle number ratio, as observed by SWIS, holds the potential to provide indirect information about the arrival of Coronal Mass Ejections (CMEs) at the Sun-Earth Lagrange Point L1. The enhanced alpha-to-proton ratio is often regarded as one of the sensitive markers of the passage of interplanetary coronal mass ejections (ICMEs) at the L1 and hence considered crucial for space weather studies. As researchers delve deeper into the collected data, the international scientific community eagerly awaits the wealth of knowledge that Aditya-L1's ASPEX is set to unveil about the enigmatic solar wind and its implications for our planet. https://lnkd.in/dwjYRhCs https://lnkd.in/dq3Taftg https://lnkd.in/dg3XukEe

Visioneering Monograin Layer (MGL) photovoltaics produced from pyrite obtained from lunar regolith. This new video was shown in the presentation by Katriin Kristmann from TalTech at the 2024 Luxembourg Space Resources Week: 25-27 March, 2024. The video was a co-production between Tallinn University of Technology, Estonia under the direction of Dr. Taavi Raadik and Astrostrom GmbH, Switzerland with Arthur Woods, Andreas Vogler, Patrick Collins and Dmitrijis Gasperovics. It illustrates the delivery of prefabricated factory modules to the surface of the Moon for the in-situ production of MGL photovoltaics for space solar power satellites to be robotically assembled at the Earth-Moon Lagrange point 1.

#SolarWind alert TY #Spaceweather.com for the data BigDataMined SOLAR RADIATION STORM--NOW: For the second time in less than a week, energetic solar protons are raining down on Earth's upper atmosphere. Forecasters call this a "solar radiation storm." Today's storm (near category S2) is rich in "hard protons" wiith energies greater than 50 MeV. It is causing a shortwave radio blackout inside the Arctic Circle and speckling the cameras of some Earth-orbiting satellites.

【The Dependence between Solar Flare Emergence and the Average Background Solar X-Ray Flux Emission】 Full article: https://lnkd.in/g7Hgmq9a (Authored by Yael Peleg, et al., from Ben Gurion University of the Negev, Israel.) The correlation between the Sun's activity, active areas (such as #sunspots), background flux, and the intensity of #solar_flares is a complex and dynamic relationship. Understanding this correlation helps scientists and researchers predict #solar_activity during different phases of the #solar_cycle. This study investigates the potential of the Sun's background X-ray flux as a tool for predicting solar flares, and analyzes data collected by solar telescopes and satellites between the years 2013 and 2023, focusing on the duration, frequency, and intensity of solar flares. #Space_Weather

Satellites burning up in the atmosphere are leaving behind particles of aluminium oxide that are damaging the ozone layer, a situation predicted to worsen as more low-Earth-orbit satellites launch. The 1987 Montreal Protocol successfully regulated ozone-damaging chlorofluorocarbons (CFCs) to protect the ozone layer, shrinking the ozone hole over Antarctica with recovery then expected in the next fifty years. However, new research from the USC Viterbi School of Engineering has shown that these oxides have increased eight-fold between 2016 and 2022 and will continue to accumulate as the number of low-Earth-orbit (LEO) satellites increase, jeopardising the ozone layer in decades to come.
