After 18 days at International Space Station, Indian astronaut Shubhanshu Shukla has embarked on his journey back from the International Space Station (ISS). The SpaceX Dragon spacecraft, carrying Shukla, will be undocked from the ISS at 4.45 PM IST. The Dragon spacecraft will be undocked from the ISS after performing two separation burns to physically distance itself from the station. Following this, it will execute the first of four planned departure burns, known as ‘Depart Burn Zero’, to move further away from the ISS. Five minutes later, it will conduct a second departure burn to ensure it cleared the keep-out sphere, a 200-meter zone surrounding the ISS designed to keep arriving and departing spacecraft at a safe distance. The spacecraft will exit the approach ellipsoid—a protective 3D boundary around the station—after 13 minutes of flight.
