**Do Private Astronauts Ne Space Mein Pehla Tareekhi Spacewalk Anjaam Diya**
WASHINGTON: Juma'rat ke din, do astronauts jo ke SpaceX capsule mein thay, aik tareekhi qadam uthatay huay duniya ka pehla private spacewalk anjaam diya. Yeh astronauts Crew Dragon spacecraft ke sath bandhe huay space ke vacuum mein thay, jab ke do dosray astronauts andar se yeh manzar dekh rahay thay, zameen se mazeed kai so mile dur.
Yeh spacewalk billionaire Jared Isaacman, jo ke 41 saal ke hain, ne lead kiya. Unho ne capsule se subha 6:52 am ET (1052 GMT) par bahar qadam rakha, aur unke sath SpaceX ki engineer Sarah Gillis, jo ke 30 saal ki hain, bhi bahar niklin. Dono pehle ghair-hukoomati afrad ban gaye jo space mein aisa task anjaam dene mein kamyab huay. Poora mission SpaceX ki website par live dikhaya gaya, taake duniya bhar ke log is lamhe ko dekh saken.
Is mission mein kuch naye aur innovative equipment bhi test kiye gaye, jin mein naye slim spacesuits aur aik naya system jo Crew Dragon cabin ko puri tarah depressurize kar sake, bhi shaamil tha. Yeh technology mustaqbil ke private space missions ke liye bohot zaroori sabit ho sakti hai.
Yeh spacewalk Elon Musk ki SpaceX company ke liye ab tak ka aik bohot hi risky challenge tha, jo ke zameen ke orbit mein insano ko bhejnay aur wapas lanay wali akeli private company hai.
"Yahan se dekhne par, Zameen bilkul ek mukammal jaga lagti hai," Isaacman ne spacecraft se bahar qadam rakhne ke baad kaha, jab ke unke peechay 700 kilometers (435 miles) niche chamakti hui duniya ka ek hissa dikhayi de raha tha.
Spacewalk shuru karne se pehle, capsule ko puri tarah depressurize kiya gaya tha, aur crew ne sirf SpaceX ke banaye huay custom-designed spacesuits ke zariye oxygen par intekhaas kiya, jo unhein spacecraft se connected ek umbilical connection ke zariye mil rahi thi. Spacewalk takreeban 30 minutes ka tha, lekin preparation aur safety procedures ki wajah se poora operation lagbhag ek ghanta aur 46 minutes tak chala. Yeh spacewalk naye spacesuits aur crew ki space mein chalne ki salahiyat ko test karne ke liye tha, aur yeh private space exploration ke liye ek bohot bara qadam tha.
Spacewalk mukammal hone ke baad, Isaacman aur Gillis wapas apni cabin seats mein aaye. SpaceX ka ground team, jo Hawthorne, California mein tha, poore process ko closely monitor kar raha tha. Hatch securely band hone ke baad capsule ka leak check kiya gaya. Spacewalk officially subha 8am ET par khatam hua.
Polaris Dawn mission ke crew mein Isaacman, Gillis, retired US Air Force lieutenant colonel Scott Poteet, 50, aur SpaceX engineer Anna Menon, 38, shaamil thay. Yeh crew Tuesday ke subha Florida se launch ke baad se Earth ke orbit mein ghoom rahe thay. Menon aur Poteet spacewalk ke dauran spacecraft ke andar hi rahe.
Yeh mission, jo Elon Musk ki company ke zariye chalaya gaya tha, commercial spaceflight ke mustaqbil mein ek bohot bara qadam hai. Isaacman, jo ke electronic payments company Shift4 ke founder hain, ne Polaris mission ko fund kiya, jaise ke unho ne 2021 mein Inspiration4 flight ke liye kiya tha. Halankeh mission ki cost ka zikar nahi kiya gaya, lekin yeh mission lakho dollar mein tha, kyun ke Crew Dragon spacecraft ka ek seat ka price takreeban $55 million hai.
NASA administrator Bill Nelson ne is mission ki tareef ki, aur kaha ke NASA ne Crew Dragon ki development mein takreeban 10 saal pehle madad ki thi. "Aaj ki kamyabi commercial space industry ke liye ek bara qadam hai aur NASA ke mustaqbil ke space economy ke iraday ko barhawa deti hai," Nelson ne social media par kaha.
**Apollo Ke Baad Sab Se Door Safar**
Crew Dragon spacecraft ne Wednesday ko Earth ka chhe dafa chakkar lagaya, ek elliptical orbit mein jo ke 190 kilometers (118 miles) tak shallow tha aur 1,400 kilometers (870 miles) tak faasla tha. Yeh mission humans ko Apollo ke missions ke baad sab se door le gaya.
Spacecraft dheere dheere apni orbit ko 700 kilometers (435 miles) tak kam kar rahi thi aur cabin pressure adjust kar rahi thi spacewalk ke liye, jo ke officially Extravehicular Activity (EVA) kehlata hai. Polaris program ke mutabiq, crew ne kaafi ghante rehearse kiye aur apne aap ko is challenge ke liye tayar kiya.
