VOYAGER 1 AT THE EDGE OF THE HELIOSPHERE

After more than four decades in space, Voyager 1 crossed the heliopause and entered interstellar space. The region contains extremely hot, ultra-thin plasma, showing just how strange the boundary between the Sun’s influence and interstellar space can be.

This holiday season, at SPARC we continue to look up.
We wish everyone health and peace, new ideas, creative collaborations, and exciting journeys!

Happy holidays and best wishes for the new year!

📡 Η ESA αξιοποιεί λογισμικό ανάλυσης δεδομένων της SPARC για την παρακολούθηση των ηλιακών καταιγίδων.

Αυτή είναι η ελληνική τεχνολογία που χρησιμοποιεί ο Ευρωπαϊκός Οργανισμός Διαστήματος για τη μελέτη των ηλιακών καταιγίδων Ανάμεσα στα διάφορα φαινόμενα των τελευταίων ημερών ήταν και ένα Επεισόδιο Εμφάνισης Ηλιακών Ενεργητικών Σωματιδίων (Solar Energetic Particle Event) που

SPARC has been awarded a contract by European Space Agency in response to the “Real-Time Assessment of Radiation Environments on Gateway” tender.

The Lunar Gateway Unified Aggregated Datasets (L-GUARD) project – our contribution to safer lunar exploration – will develop sophisticated radiation data processing schemes tailored to the radiation sensors on-board the Lunar Gateway. By combining data from the European Radiation Sensor Array (ERSA) and the Internal Dosimeter Array (IDA), we're working to provide astronauts and mission teams with precise and reliable products associated with the radiation environment encountered along Lunar Gateway’s orbit.

We're collaborating with a highly skilled consortium consisting of national research institutes, universities and SMEs:

-Office National d'Études et de Recherches Aérospatiales (ONERA)
-German Aerospace Center/Deutsches Zentrum für Luft- und Raumfahrt (DLR)
-SE2S GmbH (SE2S)
-Institute of Experimental and Applied Physics, Czech Technical -University (IEAP CTU)
-HUN-REN Centre for Energy Research (HUN-REN EK)
-Kallisto Consultancy (Kallisto)
-Aboa Space Research Oy (ASRO)
-TRAD Tests & Radiations (TRAD)
-DH Consultancy BV (DHC)



Each partner brings their expertise in radiation instrumentation, radiation detection and data analysis. Through this focused collaboration, L-GUARD will make a significant contribution to astronaut safety and mission success in the radiation environment encountered by Lunar Gateway in its near-rectilinear halo orbit.

SPARC team members delivered 3 oral presentations, convened one conference session and contributed in several poster presentations at the European Space Weather Week in ,

Looking forward to the next ESWW meeting in

Success for the SPEARHEAD project at the Interim Report Meeting! The team presented detailed updates and key findings in high-energy particle data research, receiving positive and constructive feedback from our External Evaluator, Dr. Jurgen Watermann, and Project Officer, Zoran Kovac. We are excited for the next phases of the project!
