ISRO Develops Radar for Joint NASA Mission NISAR

 

NASA and ISRO's NISAR space mission launch by January 2023, .The Indian Space Research Organization (SRO) has shipped its satellite components to NASA'S Jet Propulsion Labaratory for a joint satellite mission known as NASA-ISRO Synthetic Aperture Radar (NISAR). This joint mission, which is under development aims to provide earth observation data, that would help in the better management of natural resources and hazards. It is also meant to help scientists study the extent and pace of climate change.


Indian Space Research Organisation (ISRO) has completed development of a Synthetic Aperture Radar (SAR) capable of producing extremely high-resolution images for a joint earth observation satellite mission with the U.S. space agency National Aeronautics and Space Administration (NASA).

The Indian Space Research Organization (ISRO) has shipped
its satellite components to NASA's Jet Propulsion Laboratory for a joint satellite mission known as NASA-ISRO Synthetic
Aperture Radar (NISAR).
With a total cost estimated at US$I.5 billion, NISAR is likely to be the world's most expensive Earth-imaging satellite.
ISRO's share of the project cost is about R788 crore (US$I10 million), and NASA's share is about US$808 million.
NISAR will be the first satellite mission to use two different radar frequencies (L-band and S-band) to measure changes in our planet's surface less than a centimetre across NASA is providing the mission's L-band SAR, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder and payload data subsystem.


The 5854 kg satellite is based on the new I-6K Bus and carry 40 transponders in the Ku-band and Ka-band frequencies (32 Ka x Ku-Band Forward Link Transponders and 8 Ku * Ka band Return Link Transponders), which are capable of providing up to l6 Gbit/s throughput. GSAT-I l is India's heaviest satellite.

 जनवरी 2023 तक नासा और इसरो के NISAR अंतरिक्ष मिशन का शुभारंभ। भारतीय अंतरिक्ष अनुसंधान संगठन (SRO) ने NASA-ISRO सिंथेटिक एपर्चर रडार (NISAR) नामक एक संयुक्त उपग्रह मिशन के लिए अपने उपग्रह घटकों को NASA'S Jet Propulsion Labaratory पर भेज दिया है।  यह संयुक्त मिशन, जो विकास के अंतर्गत है, पृथ्वी अवलोकन डेटा प्रदान करना है, जो प्राकृतिक संसाधनों और खतरों के बेहतर प्रबंधन में मदद करेगा।  यह वैज्ञानिकों को जलवायु परिवर्तन की सीमा और गति का अध्ययन करने में मदद करने के लिए भी है।

 


 भारतीय अंतरिक्ष अनुसंधान संगठन (इसरो) ने संयुक्त अंतरिक्ष एजेंसी नेशनल एरोनॉटिक्स एंड स्पेस एडमिनिस्ट्रेशन (NASA) के साथ संयुक्त पृथ्वी अवलोकन उपग्रह मिशन के लिए अत्यंत उच्च-रिज़ॉल्यूशन छवियों का निर्माण करने में सक्षम सिंथेटिक एपर्चर रडार (SAR) का विकास पूरा कर लिया है।

 US $ I.5 बिलियन की अनुमानित लागत के साथ, NISAR के दुनिया के सबसे महंगे पृथ्वी-इमेजिंग उपग्रह होने की संभावना है।

 इसरो की परियोजना लागत का हिस्सा R788 करोड़ (US $ I10 मिलियन) है, और NASA का हिस्सा लगभग US $ 808 मिलियन है।

 एनआईएसएआर पहला उपग्रह मिशन होगा जो हमारे ग्रह की सतह में बदलाव को मापने के लिए दो अलग-अलग रडार आवृत्तियों (एल-बैंड और एस-बैंड) का उपयोग करेगा, जो नासा भर में एक सेंटीमीटर से कम सेंटीमीटर है, मिशन का एल-बैंड एसएआर प्रदान कर रहा है, एक उच्च दर वाला सबसिस्टम  विज्ञान डेटा, जीपीएस रिसीवर, एक ठोस राज्य रिकॉर्डर और पेलोड डेटा सबसिस्टम के लिए

Mystery brain disease found in Canada

  WHAT HAS HAPPENED? An unknown brain disease has caused panic in the New Brunswick province of Canada after a string of cases were reported that involved memory loss, hallucinations and muscle atrophy. People living in the province became cognizant of the disease after a memo from the province's public health agency leaked last week, Which asked doctors to look for symptoms relate to Creutzfeldt-Jacob disease (CJD). CJD is a rare brain disease which is caused due to abnormally folded proteins called prions. Creutzfeldt-Jakob (KROITS-felt YAH-kobe) disease (CJD) is a degenerative brain disorder that leads to dementia and, ultimately, death. Creutzfeldt-Jakob disease symptoms can be similar to those of other dementia-like brain disorders, such as Alzheimer's disease. But Creutzfeldt-Jakob disease usually progresses much more rapidly. Transmitted by contact with infected tissue, such as during a transplant or from eating contaminated meat. CAUSES NOT KNOWN FOR CURRENT DISE...

ANDHRA PRADESH STRAIN 15 TIMES MORE VIRULENT

  Experts are saying that a new Andhra Pradesh variant of the SARS-COV-2 virus is at least 15 times more virulent than the earlier ones. May be even stronger than the Indian variants of B. 1.617 and B. 1.618 . Speculation is still on regarding whether it is a new strain or the old N440K. The N440K variant was first discovered by Centre for Cellular and Molecular Biology (CCMB).However, data is still insufficient to confirm anythin. The impact of AP Strain Authorities say that the variant at present which is in circulation in Visakhapatnam is different from what we have seen during the first wave last year. Samples have been sent to CCMB for analysis, in order to find out which strain is in circulation right now.It has been observed that the new variant has shorter incubation period and the progress of the disease is much rapid. In the earlier cases, a patient infected with the virus would take at least a week to reach the hypoxia or dyspnea stage. But in the present context,...

Anti-Covid drug developed by DRDO

  WHAT HAS HAPPENED? The Drugs Controller General of India (DCG) has approved the emergency use of Drug 2-deoxy-D-glucose (2-DG) as an adjunet therapy in moderate to severe Covid-19 patients. WHO DEVELOPED IT? The Institute of Nuclear Medicine and Allied Sciences (INMAS), a lab of Defence Research and Development Organisation (DRD0), has developed the drug, In collaboration with Dr Reddy's Laboratories, Hyderabad. WHEN & HOW IT WAS DEVELOPED? In April 2020 , during the first wave of the pandemic, INMAS-DRDO scientists conducted laboratory experiments with the help of Centre for Cellular and Molecular Biology (CCMB), Hyderabad and Found that this molecule works effectively against SARS-CoV-2 virus and inhibits the viral growth. Based on these results, Drugs Controller General of India's (DCG) Central Drugs Standard Control Organization (CDSCO) permitted Phase-II clinical trial of 2-DG in COVID-19 patients in May 2020 . The DRDO, along with its industry partner DRL, Hyd...
