NASA ने इतिहास बदल दिया है. पहली बार किसी प्लैनेटरी डिफेंस टेस्ट (Planetary Defense Test) यानी डार्ट मिशन (Dart Mission) को सफलतापूर्वक पूरा किया गया.अब भविष्य में धरती के ऊपर अगर किसी तरह के एस्टेरॉयड का हमला होने की आशंका होती है. तो इस तकनीक से पृथ्वी को बचाया जा सकता है. क्योंकि भविष्य में हमारे... नीले ग्रह को सबसे ज्यादा खतरा अगर किसी चीज से है तो वो है एस्टेरॉयड. इसके बाद है जलवायु परिवर्तन या ग्लोबल वॉर्मिंग.  डार्ट मिशन ने 27 सितंबर 2022 यानी सुबह 4.45 मिनट पर एस्टेरॉयड डिडिमोस (Didymos) के चंद्रमा जैसे पत्थर डाइमॉरफोस (Dimorphos) से टकराया. डार्ट यानी (Double Asteroid Redirection Test - DART). मकसद पूरा हुआ. स्पेसक्राफ्ट ने एस्टेरॉयड से टक्कर कर ली है. डाइमॉरफोस किस दिशा में मुड़ा है. इसका डेटा आने ... में थोड़ा समय लगेगा.  DART, NASA's First Planetary Defense Test Mission. NASA's first test mission for planetary defense, the Double Asteroid Redirection Test (DART) seeks to test and validate a method to protect Earth in case of an asteroid impact threat. NASA’s DART Mission Hits Asteroid in First-Ever Planetary Defense Test - After 10 months flying in space, NASA’s Double Asteroid Redirection Test (DART) – the world’s first planetary defense technology demonstration – successfully impacted its asteroid target on Monday, the agency’s first attempt to move an asteroid in space. Mission control at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, announced the successful impact at 7:14 p.m. EDT. As a part of NASA’s overall planetary defense strategy, DART’s impact with the asteroid Dimorphos demonstrates a viable mitigation technique for protecting the planet from an Earth-bound asteroid or comet, if one were discovered. “At its core, DART represents an unprecedented success for planetary defense, but it is also a mission of unity with a real benefit for all humanity,” said NASA Administrator Bill Nelson. “As NASA studies the cosmos and our home planet, we’re also working to protect that home, and this international collaboration turned science fiction into science fact, demonstrating one way to protect Earth.” DART targeted the asteroid moonlet Dimorphos, a small body just 530 feet (160 meters) in diameter. It orbits a larger, 2,560-foot (780-meter) asteroid called Didymos. Neither asteroid poses a threat to Earth. The mission’s one-way trip confirmed NASA can successfully navigate a spacecraft to intentionally collide with an asteroid to deflect it, a technique known as kinetic impact. The investigation team will now observe Dimorphos using ground-based telescopes to confirm that DART’s impact altered the asteroid’s orbit around Didymos. Researchers expect the impact to shorten Dimorphos’ orbit by about 1%, or roughly 10 minutes; precisely measuring how much the asteroid was deflected is one of the primary purposes of the full-scale test. “Planetary Defense is a globally unifying effort that affects everyone living on Earth,” said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “Now we know we can aim a spacecraft with the precision needed to impact even a small body in space. Just a small change in its speed is all we need to make a significant difference in the path an asteroid travels.” The spacecraft’s sole instrument, the Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO), together with a sophisticated guidance, navigation and control system that works in tandem with Small-body Maneuvering Autonomous Real Time Navigation (SMART Nav) algorithms, enabled DART to identify and distinguish between the two asteroids, targeting the smaller body. These systems guided the 1,260-pound (570-kilogram) box-shaped spacecraft through the final 56,000 miles (90,000 kilometers) of space into Dimorphos, intentionally crashing into it at roughly 14,000 miles (22,530 kilometers) per hour to slightly slow the asteroid’s orbital speed. DRACO’s final images, obtained by the spacecraft seconds before impact, revealed the surface of Dimorphos in close-up detail. Credits - NASA.
