Satellite Aur Launch Vehicles Kya Hain? Janiye Iska Rochak Itihas Aur Khoobiyan
Dosto, jab bhi hum aakash ki taraf dekhte hain, toh hamare dimaag mein ek hi sawal aata hai ki space mein udne wale ye satellites aur rockets aakhir kaam kaise karte hain? Aaj ke is special article mein hum bilkul aasan bhasha mein samjhenge ki Satellite kya hai, ye kitne prakar ke hote hain, aur inhein space mein bhejne wale Launch Vehicles (Rockets) ki duniya kaisi hai.
1. Satellite (Upagrah) Kya Hai?
Simple shabdon mein kahein toh, har woh cheez jo kisi badi cheez ke charo taraf chakkar lagati hai, use satellite kehte hain. Satellites do tarah ke hote hain:
- Natural Satellite (Prakritik Upagrah): Jaise hamari Prithvi Suraj ke chakkar lagati hai aur Chandrama hamari Prithvi ke chakkar lagata hai.
- Artificial Satellite (Man-made Upagrah): Yeh insaanon dwara banayi gayi machines hoti hain, jinhein aakash mein live data, weather forecasting, GPS navigation aur communication ke liye bheja jata hai.
2. Satellite Ka Rochak Itihas (History)
Duniya ka sabse pehla man-made satellite Sputnik 1 tha, jise 4 October 1957 ko Soviet Union (Russia) ne launch kiya tha. Iska size sirf ek beach ball jitna tha aur ise dharti ka ek chakkar lagane mein 98 minutes ka samay lagta tha.
Agar hum **Bharat (ISRO)** ki baat karein, toh India ka pehla satellite Aryabhata tha, jo 19 April 1975 ko launch kiya gya tha. Iske baad 1980 mein Bharat ne apne khud ke launch vehicle SLV-3 se Rohini satellite ko orbit mein set karke itihas rach diya tha.
3. Launch Vehicle (Rockets) Kya Hote Hain?
Kisi bhi satellite ko space mein bhejne ke liye jis vehicle ka use hota hai, use Launch Vehicle ya Carrier Rocket kehte hain. Yeh rockets bohot hi majboot hote hain aur inke mukhya roop se 4 stages hote hain, jo alag-alag unchai par pahunchkar fuel khatam hone par alag hote rehte hain.
Duniya ke kuch mukhya deshon ke prasiddh launch vehicles neeche diye gaye hain:
| Space Agency / Desh | Prasiddh Launch Vehicles (Rockets) |
|---|---|
| ISRO (India) | PSLV, GSLV, GSLV Mk III (LVM3), ASLV |
| NASA / SpaceX (USA) | Saturn V, Falcon 9, Falcon Heavy, Starship |
| CNSA (China) | Long March Family (Long March 2, 3, 5) |
| Roscosmos (Russia) | Soyuz Family, Proton-M, Angara |
4. Satellite Ke Mukhya Parts (Components)
- Antennas: Signals ko receive aur transmit karne ke liye.
- Power System: Surya ki roshni ko energy mein badalne ke liye Solar Arrays (Panels).
- Transponders: Uplink frequencies ko badal kar amplify karne ke liye, jisse TV aur Internet chalta hai.
- Thermal Control: Space ki extreme garmi aur sardi se satellite ko bachane ke liye.
