कौनोतोरी (सफ़ेद सारस) प्रयोग क्या है

जापान ने शुक्रवार को कौनोतोरी नाम का स्पेस कैप्सूल अंतरिक्ष में भेजा जिसका काम अंतरिक्ष कचरे को साफ करना है जो पृथ्वी के चक्कर लगा रहें  है |
अंतरिक्ष कचरा या स्पेस जंक छोटे बड़े अंतरिक्ष यान उपग्रह  या किसी अंतरिक्ष मिशन के अवसिस्ट  है जो अब कार्य नहीं कर रहे और अंतरिक्ष में तेजी से घूम रहे है | ये  वर्त्तमान अंतरिक्ष यानो के लिए भारी खतरा बने हुए है ,इसलिए इस कचरे को साफ करना बेहद जरुरी हो गया है इसी दिशा में जापान ने एक कदम उठाया है ,इस लिए  उसने कौनोतोरी नाम का कप्सुल अंतरिक्ष में भेजा है ताकि इस दिशा में प्रयोग किया जा सके |
इसके लिए कैप्सूल सात सौ मीटर मेटैलिक लाइन का प्रयोग करेगा जो की एक विद्युतिये तार का काम करेगा यह अल्मुनियम और स्टेनलेस स्टील से बना हुआ जाल है | इसकी मदद से  कचरे की गति को कम करने का प्रयास किया जायेगा ताकि वह अंततः पृथ्वी के वायुमंडल में घुसकर नष्ट हो जाये |

फिक्र न कर

कहते है की असफलता ही सफलता की कुंजी है ,ये बात तो बहुत छोटी सी है लेकिन सफलता का राज इसमें छिपा है | कोई भी सब कुछ सीख कर पैदा नहीं होता ,सब यही सीखते है इसी  दुनिया में , यहाँ आदमी सिखने के लिए ही पैदा होता है | हाँ ये बात अलग है की कोई बड़ा जल्दी सीख लेता है और कोई थोड़े समय में ,और हम सिखने के क्रम में कितनी बार हारते है ,असफल होते है और अंततः सीख लेते है समझिए सफल होते है | शायद यही बात प्रतियोगिता , परीक्षा के लिए भी लागु होता है  हम हमेशा सीखते है हारकर भी , 
इसलिए   कर्म किये जा ,फल की तू फिक्र न कर ||


सिने में तूफान  छुपा है ,
आँखों में आसमान  है |
दुनिया हो मेरी  मुठी में 
ऐसे ही अरमान है ||

कस्ती लगेगी किनारे 
ऐ मन तू फिक्र न कर |
आगे देख चलता रह ,
रुकने की तू जिक्र न कर ||

जिन्दा है तू तो संघर्ष कर ,
मंजिल ही तेरा सुकून है |
तू जिन्दा है ,इस धरती पर ,
जब तक तुझमे जूनून है ||

 -----विहान

जिद

एक सूनापन सा है आँखों में ,
दिल में एक तन्हाई सी है |
कुछ कचोटता है सिने में ,
दिल की खुद से बेवफाई सी है |


जीवन की राहें  रूकती नहीं ,
और जीनें की जज्बा है की झुकती नहीं |
लौ सुलगती  रही है उठने  को ऊपर,
पर  झुकाने को निचे ,बारिश है की रूकती नहीं ||



अब सोच की छतरियों से काम नहीं चलता ,
हिम्मत से कम लेनी पड़ेगी ||
चोट भले ही थोड़ी  खानी पड़े ,
पर  राह - ए मंजिल बनानी पड़ेगी ||

Locational Accuracy

Angels of locational accuracy

Satellite navigation system consist of satellites that provide spatial positioning and enables hand held devices to determine accurate position using time signal

Current global satellite navigation systems

    Global positioning system (GPS) :

    the most utilised system .consist of up to 32 medium orbit satellites. Operational            since 1978 and globally available since 1994

    GLONASS (Global navigation satellite system ) :
   consists of 24 satellite ,operated by Russian aerospace defence forces

   DORIS ( Doppler orbitography and radio positioning integrated by satellite )

   French precision navigation system based on static emitting station around the world.    Limited in uses and coverage. used with other global navigation satellite system           (GNSS)

Navigation system under development

          Galileo

           To be managed and operated by the European union (EU) and European space              agency (ESA)

         BeiDou

          Managed by china .currently functional in Asia pacific as a  16 satellite system

India and its satellite navigation plan

             India has a two pronged satellite navigation Sat Nav plan

           GAGAN
           GPS aided geo augmented navigation


           IRNSS
            Its full form is  Indian regional navigation satellite system

            It is a 7 satellite navigation system.   In this Indian space agency ISRO have already established 4 satellite in orbit ,and by march 2016 all satellite will be in orbit and by mid . 2016.
