Shubhanshu Shukla’s 22-Hour Journey Back to Earth: Why the Long Trip on SpaceX Dragon?
Indian astronaut Shubhanshu Shukla’s return journey from space is generating considerable interest, especially the 22-hour duration it will take him to reach Earth aboard the SpaceX Dragon spacecraft. Unlike quick descents in fictional movies, real-world space travel involves complex procedures and orbital mechanics that dictate the return timeline.
Understanding the Orbital Mechanics
The Dragon spacecraft doesn’t simply drop straight down to Earth. It follows a carefully calculated trajectory that involves gradually lowering its orbit and then performing a deorbit burn. This controlled descent is crucial to manage the spacecraft’s speed and ensure it enters the Earth’s atmosphere at the correct angle.
The Deorbit Burn and Atmospheric Entry
The deorbit burn is a critical maneuver using the Dragon’s thrusters to slow it down, allowing gravity to pull it out of orbit. Once it enters the Earth’s atmosphere, the spacecraft encounters friction, generating intense heat. The Dragon’s heat shield protects the astronauts during this fiery re-entry phase.
Splashdown and Recovery
Following the atmospheric descent, the Dragon utilizes parachutes to slow its descent further before splashing down in the ocean. Recovery teams are then deployed to retrieve the spacecraft and the astronauts, ensuring their safe return after their mission in space. This retrieval process also contributes to the overall return time.
