SpaceX Polaris Dawn Mission: Elon Musk’s company SpaceX has created history in space. This was the first private space mission which has achieved success. This company’s Polaris Dawn crew, which carried four astronauts, has made a successful return. It landed on the Tortugas Coast of Florida at around 1 pm on Saturday afternoon. During this period, massive security arrangements were made

This five-day mission was launched on September 10. During this mission, two astronauts also performed a spacewalk.

The campaign was led by fintech billionaire Jared Isaacman. Apart from them, Kid Poteet, Sarah Gillis and Anna Menon were also aboard the spaceship. All of them started their journey from Kennedy Space Center. These spacecraft were launched on Musk’s company’s Falcon-9 rocket.

His journey was also dangerous because he went to a place where no astronaut had gone in the last 50 years. These people went to a distance of 1408.1 km in orbit. This distance is deeper than the International Space Station located in space.

On Thursday, their spacecraft was brought down to 434 miles. Here mission commander Isaacman opened the hatch and performed the spacewalk. “SpaceX, back home we all have a lot of work to do, but from here, Earth certainly looks like an ideal world,” he said in a message to Mission Control in Hawthorne, California.

इसके बाद टीम ने जमकर सेलिब्रेट किया। वह कुछ मिनटों के बाद वापस अंदर चले गए और दूसरी अंतरिक्ष यात्री, स्पेसएक्स इंजीनियर सारा गिलिस बाहर आईं और उन्होंने अंतरिक्ष में चहलकदमी की

After this the team celebrated vigorously. He went back in after a few minutes and the other astronaut, SpaceX engineer Sarah Gillis, came out and did a spacewalk

वापसी रही चैलेंजिंग
इस मिशन का सबसे बड़ा चैलेंज था इसकी वापसी। स्पेसक्राफ्ट ने धरती के वायुमंडल में जब प्रवेश किया तो उसकी रफ्तार करीब 27000 किमी प्रति घंटे थी। हवा से टकराहट के बाद तापमान 1900 डिग्री सेल्सियस तक पहुंच चुका था। हालांकि स्पेसक्राफ्ट के नीचे लगी चार मीटर चौड़ी हीटशील्ड ने इसको बचाए रखा।

return was challenging The biggest challenge of this mission was its return. When the spacecraft entered the Earth’s atmosphere, its speed was about 27000 km per hour. After the collision with the air, the temperature had reached 1900 degrees Celsius. However, the four meter wide heat shield below the spacecraft kept it safe.

As it came down its speed was controlled. Finally the parachutes were opened and landed in water. The rescue team conducted tests before evacuating the astronauts and taking them to the ground.

SpaceX Polaris Dawn Mission: A Historic Milestone
The Polaris Dawn mission was a groundbreaking spaceflight conducted by SpaceX in September 2024. Led by tech entrepreneur Jared Isaacman, the mission aimed to push the boundaries of commercial space exploration and set new records.
Key Achievements

• First Commercial Spacewalk: The crew successfully performed the first-ever commercial spacewalk, a significant step towards expanding private sector involvement in space activities.
• Record-Breaking Altitude: The mission reached an orbital altitude of 1,400 kilometers above Earth, surpassing the previous record set by NASA’s Gemini 11 mission.
• Radiation Belt Research: The crew conducted valuable research on the effects of space radiation on human health, which is crucial for future long-duration missions to the Moon and Mars.
• Testing of New Technologies: The mission served as a testbed for new technologies, including SpaceX’s newly developed extravehicular activity (EVA) suits.
  Crew Members
  The Polaris Dawn mission was crewed by four individuals:
• Jared Isaacman: Commander and mission financier
• Scott “Kidd” Poteet: Former US Air Force pilot
• Anna Menon: SpaceX engineer
• Sarah Gillis: SpaceX engineer
  The Crew Dragon Capsule
  The mission was carried out aboard a SpaceX Crew Dragon capsule, which has become a reliable and versatile spacecraft for human spaceflight.
  

The Polaris Dawn mission served as a significant milestone in SpaceX’s pathway to future space travel. It demonstrated several crucial capabilities and set the stage for future commercial space exploration:

• Commercial Spacewalks: The mission successfully conducted the first-ever commercial spacewalk, proving the viability of private sector involvement in such complex activities. This opens the door for future commercial space stations, research facilities, and even space tourism.
• High-Altitude Flight: By reaching a record-breaking altitude of 1,400 kilometers, the mission showcased SpaceX’s ability to launch and operate spacecraft in challenging environments. This experience is invaluable for future missions to the Moon and Mars.
• Technology Testing: The mission served as a testbed for new technologies, including SpaceX’s EVA suits and other systems. This helps identify potential issues and refine designs for future missions.
• Scientific Research: The crew conducted valuable research on the effects of space radiation on human health, which is essential for understanding the challenges of long-duration spaceflight. This information can be used to develop countermeasures and ensure the safety of future astronauts.
• Public Engagement: The Polaris Dawn mission generated significant public interest and excitement, helping to inspire a new generation of space enthusiasts. This increased public support is crucial for the continued development of commercial space exploration.
  Overall, the Polaris Dawn mission was a successful demonstration of SpaceX’s capabilities and a significant step forward in the commercial space industry. It has paved the way for future missions to the Moon, Mars, and beyond.
