NASA's newsletter

 

NASA Newsletter In this week's newsletter, take a look at comet 3I/ATLAS through the lenses of NASA's spacecraft and space telescopes; find out when and where to watch NASA astronaut Chris Williams launch aboard the Roscosmos Soyuz MS-28 spacecraft to the International Space Station; and discover the process behind NASA's Centennial Challenges, which have awarded more than $24 million to hundreds of people ranging from academics, startup founders, and small business owners from across the U.S. and 86 countries to bring bold ideas to NASA. Plus, more stories you might have missed.   SCIENCE Through NASA’s Lenses NASA is in the midst of an unprecedented solar system-wide observation campaign, turning its spacecraft and space telescopes to follow comet 3I/ATLAS, the third known interstellar object to pass through our solar system. Twelve NASA assets have captured and processed imagery of the comet since it was first discovered on July 1, and several others will have opportunities to capture more images as the comet continues to pass through our solar system.

Γιατί μια τεράστια ανωμαλία στο μαγνητικό πεδίο της Γης προβληματίζει τη NASA

"...Εδώ και χρόνια, η NASA παρακολουθεί μια παράξενη ανωμαλία στο μαγνητικό πεδίο της Γης: μια τεράστια περιοχή χαμηλότερης μαγνητικής έντασης στους ουρανούς, που εκτείνεται μεταξύ της Νότιας Αμερικής και της νοτιοδυτικής Αφρικής.

Αυτό το εξελισσόμενο φαινόμενο ονομάζεται Ανωμαλία του Νότιου Ατλαντικού (South Atlantic Anomaly ή SSA) και απασχολεί τους επιστήμονες εδώ και δεκαετίες, κυρίως εκείνους της NASA. Και αυτό γιατί τα διαστημόπλοια και οι δορυφόροι (συμπεριλαμβανομένου του Διεθνούς Διαστημικού Σταθμού), περνούν απευθείας μέσα από την SSA καθώς κάνουν κύκλο γύρω από τη Γη σε χαμηλή τροχιά, αναφέρει το Science Alert....."

Airborne Data Applications for Invasive Species Mapping           In this training offered by NASA’s Applied Remote Sensing Training Program (ARSET), scientists will discuss the applications of airborne and in situ field data for mapping and monitoring terrestrial invasive species using datasets acquired during the BioSCape campaign in South Africa. The training will take place on Sept. 30, 2025.                   Learn more about the BioSCape project, an international collaboration between South Africa and the United States to study biodiversity in South Africa's Greater Cape Floristic Region. ➞                       Articles
