🔭 Capturing the Beauty of Comet C/2023 A3 (Tsuchinshan–ATLAS) from Australia! 🌠 At Spaceflux, our roots in #astronomy continue to shape our approach to space situational awareness and orbital safety. On September 27, 2024, at 19:15 UT, we captured this stunning image of #comet C/2023 A3 (Tsuchinshan–ATLAS), 134 million km from Earth, using our 35-cm telescope based in Australia. While this comet poses no immediate threat, it represents the celestial wonders that make our work as important as it is exciting. Our longstanding collaboration with Telescope Live Ltd allows us to produce precise astronomical observations, contributing not only to space situational awareness but also to planetary #defense by tracking potentially hazardous objects. Observation Details 📅 Date & Time: Sept. 27, 2024, 19:15 UT  📍 Location: Spaceflux Telescope, Australia  📊 Exposure: 12x30-second capture, comet positioned +8 degrees on the horizon. This observation reminds us that natural objects like comets can intersect with vital orbital regions. By tracking them, we help ensure a safer space environment for #satellites, commercial operations, and beyond. Feel free to reach out to learn how Spaceflux’s expertise in both space safety and planetary observation can help you secure your space assets. #SSA

With revised technique and calculations, I found that the faintest star visible in this frame is of magnitude 13.8 (see comment below). So I reasonably estimated the debris streak at 1 magnitude fainter. Had the telescope been tracking the debris, it would have stayed on one (binned) pixel in the 200ms exposure, appearing as an object of magnitude 9 (calculated separately/updated), giving it a size of approximately 10-11cm at its calculated altitude of 445km (calculated from the length of the streak against the FOV and exposure). This is fairly close to our target of achieving detection of 10cm or smaller LEO objects.

For my network of SAR experts, this post is probably stupidly obvious .. for anyone else, did you know the "synthetic aperture" in SAR is created by the movement of the instrument itself, typically from the movement of a satellite in orbit, or an aircraft flying? In other words, instead of having a massive antenna, the satellite will "fake" it by moving along its orbit. (I found this fact to not be well documented, and it seems like one of the fundamental assumptions with SAR technology). Something that is better documented is the synthetic aperture of the Event Horizon telescope. (remember all those amazing black hole images). In this case, telescopes are placed all over the Earth and we essentially use our planet as the aperture!! In other words, we synthesize a telescope with an effective opening equal to the diameter of Earth to look deep into the cosmos. I created a repo of some basic language SAR information here; feel free to add or create a ticket! https://lnkd.in/grPP575b image credit: https://lnkd.in/gAQHtR8C #SAR #remotesensing #satellite #radar #radarsystems

Space tourists need better warnings about cosmic radiation exposure, say experts , USA Space Flight Regulation, showing relevant government agencies and legislation for flight operations. Credit: Space Policy (2024). DOI: 10.1016/j.spacepol.2024.101613 Space weather experts at the University of Surrey are urging regulators and space tourism innovators to work together to protect their passengers and crews from the risks of space weather radiation exposure.

Neuraspace New Telescope to Assist the Portuguese Air Force🔭 Neuraspace and the Portuguese Air Force have launched a collaboration to boost airspace security and space sustainability with the installation of Neuraspace’s first operational optical telescope at Air Base No. 11 in Beja, Portugal. Part of the “AI Fights Space Debris” project, this advanced telescope integrates with Neuraspace’s Space Traffic Management Platform, using AI to ensure safe satellite operations and prevent collisions with space debris. This partnership is set to strengthen Portugal’s space situational awareness and tracking capabilities, enhancing data analysis and safety protocols for satellite operators worldwide.

🔦 Have you ever 𝙨𝙚𝙚𝙣 communication between ground and space? Our ground segment engineers at #ESOC are shaping the future of space communications by exploring the potential of optical technologies to transmit information between ground stations and space missions. Located in the Canary Islands, Izaña-1 ground station (IZN-1) is a testbed for ESA's optical technologies, amongst them optical communication, a technology that would allow increased bandwidth over radio at low equipment mass, power consumption and interference. Caught on tape this summer, this is what the 1590nm laser beacon emitted from the IZN-1 station looks like from space (the bright spot on the eastern part of the island of Tenerife in the video). The IZN-1 station is home to many other space optical innovations, such as laser ranging which uses short laser pulses to determine the orbit of space objects - from satellites to space debris. 📸 Alisio-1, Instituto de Astrofísica de Canarias (IAC) Learn more about this ground station 👉 https://lnkd.in/ePC-cTHf

This week’s flight data - the blue plot shows the effective dose exposure for a commercial flight at ~40,000ft, from Galactic Cosmic Rays (GCRs), during February 2024. The orange plot shows the impact on effective dose rates from a severe Ground Level Enhancement (GLE) event, which can occur approximately once in every 100 years. The resultant effective dose for the whole flight, increases from 14µSv to 175µSv (equivalent to ~35 dental x-rays), due to the GLE event. Part of my research with University of Surrey looks at the radiation hazards from GLEs / space weather and the risk mitigation for very high altitude ‘near space’ flights, and we’ll be publishing a number of papers on this topic in the next few months. #Radiation #Risk #Spaceweather

[🧠 Did You Know… #9] Why are our nanosatellites so… shiny? In space, where there's no air, temperatures can fluctuate dramatically, swinging from freezing to scorching in the blink of an eye. 🌌 🌟To ensure our nanosatellites can weather these extreme conditions, they are equipped with a Multi-Layer Insulation (MLI). Imagine this: our satellites are wrapped in not one, not two... but ten layers of super shiny, reflective covers. These layers act like a space-age thermal blanket, shielding the instruments inside the satellite from the harsh temperature swings of the cosmos. ☀️❄️ So next time you gaze up at the stars and wonder how our satellites brave the cosmic chill and heat, remember the marvel of MLI keeping them safe and sound in the vastness of space! 🌠 #Kineislaunch #KineisConstellation #Space #Satellite

when we talk about cosmic energy we refer to the sun.What if extra terrestrial are capable of harnessing it for space travel and able to control the amount of cosmic radiation from the sun.
