Glossary term: कृत्रिम उपग्रह

Description: कृत्रिम उपग्रह एक मानव निर्मित उपकरण है जिसे पृथ्वी या अन्य सौर मंडल की वस्तुओं की परिक्रमा करने के लिए अंतरिक्ष में भेजा जाता है, जहां गुरुत्वाकर्षण इसे कक्षा में रखता है। कृत्रिम उपग्रहों को विभिन्न प्रकार के कार्यों को करने के लिए डिज़ाइन किया जा सकता है, जिसमें मौसम विज्ञानियों को मौसम की भविष्यवाणी करने में मदद करने के लिए पृथ्वी की हवाई तस्वीरें लेना, या खगोलीय पिंडों और दूर की आकाशगंगाओं की तस्वीरें लेना शामिल है, जिससे वैज्ञानिकों को ब्रह्मांडीय प्रणाली को बेहतर ढंग से समझने में मदद मिलती है। कृत्रिम उपग्रहों का उपयोग मुख्य रूप से विश्वव्यापी संचार और किसी के स्थान का पता लगाने के लिए भी किया जाता है, जैसे ग्लोबल पोजिशनिंग सिस्टम (जीपीएस)। पहला कृत्रिम उपग्रह १९५७ में सोवियत संघ द्वारा लॉन्च किया गया था और इसे स्पटनिक १ कहा गया था।

Bright streaks form vertical bars, obscuring the starry sky

Satellite swarm versus night sky beauty, by Torsten Hansen, Germany

Caption: Third place in the 2021 IAU OAE Astrophotography Contest, category Light pollution. This image of Venus and the Pleiades also shows the tracks of the Starlink satellites. These satellites which are located at an altitude of approximately 550 kilometres, are part of an ever-growing constellation of satellites aimed to provide worldwide internet access. The reflective surfaces of the satellites, coupled with the fact that they are orbiting around the Earth, means that astronomical observations which require very long exposures capture “tracks” of the satellites in their images. Astronomical images used for scientific research are not usable because the measurements and data will contain these “tracks”. Because the number of satellites is expected to grow, it is likely that in the near future there will be no place on Earth where these satellites will not be visible crossing the sky. This is a new type of light pollution that seems to be an upcoming problem we will have to deal with, as these satellites might prevent optimal observation of the sky.
