International Space Station (ISS): Insaniyat Ka Khala Mein Sab Se Bara Mission – Mukammal Maloomat

by

Dunya ki tareekh mein insan ne hamesha sitaron par kamand dalne ki koshish ki hai. Inhi koshishon ka nateeja International Space Station (ISS) hai. Ye sirf ek space station nahi, balki insani aqal, engineering aur dunya bhar ke mulkon ke ittehad ki ek aisi misal hai jo zameen se 400 kilometer upar hamari saron par gardish kar rahi hai. Is article mein hum ISS ki tameer, iska maqsad, wahan ki zindagi aur iske mustaqbil par detail mein baat karenge.

1. ISS Kya Hai? (Ek Jami’ Ta’aruf)

International Space Station (ISS) ek bohat bari, rehne ke qabil (habitable) artificial satellite hai jo zameen ke nichle madar (Low Earth Orbit) mein maujood hai. Ye dunya ki sab se bari Space Laboratory hai jahan scientist microgravity (kam sakal) ke mahool mein experiments karte hain.

ISS ko kisi ek mulk ne nahi banaya. Ye America (NASA), Russia (Roscosmos), Europe (ESA), Japan (JAXA) aur Canada (CSA) ka ek mushtarka project hai. 1998 mein iska pehla module launch kiya gaya tha aur tab se ye musalsal bara hota gaya hai.

2. ISS Ki Tameer: Ek Mushkil Tareen Safar

ISS ki tameer koi asan kaam nahi tha. Iska size itna bara hai ke ise ek sath space mein nahi bheja ja sakta tha. Is liye ise chote chote tukron mein bhej kar wahan jora gaya.

  • Pehla Qadam (1998): Russia ne sab se pehla module Zarya launch kiya. Iske kuch din baad America ne Unity module bheja.
  • Assembly: 1998 se 2011 tak, 30 se zyada flights (Space Shuttles aur Russian rockets) ke zariye iske mukhtalif hisse upar bheje gaye.
  • Modules aur Nodes: ISS mein rehne ke liye alag kamre hain, jinhein Modules kaha jata hai. Har module ka apna maqsad hai, jaise Columbus Lab (Europe) aur Kibo Lab (Japan).

3. ISS Ki Raftar aur Orbit (Zameen ke Gird Chakkar)

ISS ki raftaar dunya ki kisi bhi bullet train ya jahaz se hazaron guna zyada hai.

  • Speed: Ye takreeban 28,000 kilometers per hour (17,500 mph) ki raftaar se chalta hai.
  • Time: Ye har 90 minutes mein zameen ka ek pura chakkar laga leta hai.
  • Din aur Raat: ISS par maujood astronauts ek 24 ghante ke din mein 16 martaba suraj ko nikalte aur doobte hue dekhte hain.
  • Altitude: Ye zameen se takreeban 400 se 420 kilometers ki bulandi par rehta hai. Is bulandi ko برقرار (maintain) rakhne ke liye ise waqtan fawaqtan apne engines ka istemal karna parta hai.

4. ISS Ka Size aur Structure

Agar hum ISS ko zameen par rakhein, to ye ek American Football Field (takreeban 109 meters lambi) jitni jagah gherega.

  • Wazan: Iska kul wazan takreeban 450,000 kg hai.
  • Solar Panels: ISS ke upar bohat bare Solar Arrays lage hue hain jo suraj ki roshni ko bijli mein tabdeel karte hain. In panels ka phelao itna hai ke ye kisi bari building ko cover kar sakte hain.
  • Pressurized Volume: Iske andar rehne ki jagah takreeban ek Boeing 747 jahaz jitni hai, lekin iska interior hissa 6 se 7 logon ke liye kafi wasee hai.

5. Khala Mein Zindagi: Astronauts Kaise Rehte Hain?

Space mein rehna sun’ne mein jitna exciting lagta hai, haqiqat mein ye utna hi mushkil hai. Astronauts ko makhsoos qanoon aur discipline par amal karna parta hai.

A. Weightlessness (Microgravity)

ISS par gravity boht kam hoti hai, is liye har cheez hawa mein teirti hai. Hatta ke insan bhi udte hain. Is mahool mein kaam karna seekhne mein mahino lagte hain.

B. Khana aur Peena

Astronauts ka khana zameen se Dehydrated (khushk) form mein bheja jata hai. Wo is mein pani mila kar khate hain. Namak aur mirch liquid form mein hote hain kyunke powder hawa mein ud kar astronauts ki aankhon ya nose mein ja sakta hai.

Water Recycling: ISS par pani boht keemti hai. Wahan astronauts ka pasina aur urine (peshab) filter kar ke dobara peene ke pani mein tabdeel kiya jata hai. Ye technology itni advanced hai ke ye zameen ke kisi bhi filter se behtar pani saaf karti hai.

C. Exercise aur Sehat

Zameen par gravity hamari haddiyon aur muscles ko mazboot rakhti hai. Space mein gravity na hone ki wajah se haddiyan kamzor (Osteoporosis) hone lagti hain. Is liye har astronaut ko rozana 2 se 2.5 ghante exercise karni parti hai. Wahan makhsoos treadmill aur weight-lifting machines hoti hain jo unhein fit rakhti hain.

D. Neend

Wahan koi bed ya takiya nahi hota. Astronauts sleeping bags ko deewar ke sath vertical (khara kar ke) baandh dete hain taake wo sote waqt hawa mein na urein aur kisi machine se na takrayein.

6. ISS Ka Maqsad: Science aur Research

ISS ko banane ka sab se bara maqsad aisi research karna hai jo zameen par namumkin hai.

  1. Biology aur Medicine: Scientist dekhna chahte hain ke khala mein DNA kaise behave karta hai. Cancer ki dawaiyon aur Alzheimer’s jaisi bimariyon par wahan research hoti hai.
  2. Physics: Microgravity mein aag (fire) ka behaviour badal jata hai. Zameen par aag ooper ki taraf jati hai, lekin ISS par aag Gole (sphere) ki shakal ikhtiyar kar leti hai.
  3. Future Space Travel: Agar insan ko Mars (Mareekh) par jana hai, to use mahino ya saalon space mein rehna hoga. ISS par hone wali research humein batati hai ke insani jism itne lambe safar ko kaise bardasht karega.
  4. 3D Printing: ISS par ab 3D printers ka istemal kar ke insani tissues aur organs banane ki koshish ki ja rahi hai.

7. ISS Ko Kaise Dekha Jaye?

Kya aap ko maloom hai ke aap ISS ko apni nangi aankh se dekh sakte hain? Ye asman mein kisi boht tez chamakte hue jahaz ki tarah nazar aata hai jo bina kisi awaz ke tezi se guzar jata hai.

  • Best Time: Suraj nikalne se pehle ya suraj doobne ke foran baad.
  • App: NASA ki Spot the Station website ya mobile apps ke zariye aap jaan sakte hain ke ISS kab aapke shehar ke upar se guzre ga.

8. ISS Par Hone Wali Pareshaniyan aur Khatrat

Space station par rehna khatre se khali nahi hai.

  • Space Debris: Purane satellites ke tukre ya chote pathar (meteoroids) ISS se takra sakte hain. Chonke ISS ki raftar boht tez hai, is liye ek chota sa tukra bhi goli (bullet) se zyada nuqsan pahuncha sakta hai.
  • Radiation: Zameen ka atmosphere humein suraj ki khatarnak rays se bachata hai, lekin ISS par astronauts ko zyada radiation ka samna karna parta hai, jis se cancer ka khatra barh jata hai.
  • Technical Faults: Oxygen generator ka kharab hona ya air leak hona maut ka sabab ban sakta hai.

9. ISS Ka Mustaqbil

Har machine ki ek life hoti hai. ISS ab purana ho raha hai. Iske modules mein dararein (cracks) aur technical masle barh rahe hain.

  • 2030 ka Plan: NASA aur partner agencies ne faisla kiya hai ke ISS ko 2030 tak chalaya jayega.
  • The End: 2031 mein, ISS ko control kar ke zameen ki taraf laya jayega aur ye Pacific Ocean (samundar) ke ek sunsan ilake, jise Point Nemo kehte hain, mein gira diya jayega.
  • Commercial Stations: ISS ke baad, private companies jaise SpaceX, Blue Origin aur Axiom Space apne naye space stations banayengi jahan aam shehri (space tourists) bhi ja sakenge.

10. Aakhri Baat

International Space Station insani zahanat ki akasi karta hai. Ye humein sikhata hai ke jab dunya ke mukhtalif rang, nasal aur mazhab ke log ek maqsad ke liye jama hote hain, to wo sitaron se aage ki dunya ko bhi chhoo sakte hain. ISS ne humein bataya ke zameen upar se kaisi dikhti haiek aisi jagah jahan koi sarhad (borders) nazar nahi aati.

ISS ka safar shayad 2031 mein khatam ho jaye, lekin is se milne wala ilm aur tajurba insan ko agle hazaron saalon tak space ki gehraiyon mein le jane mein madadgar sabit hoga.
