NEW DELHI: Astronaut Shubhanshu Shukla is set to return to India on Sunday following his historic visit to the International Space Station (ISS) and is eager to share his experiences with friends and colleagues, as ISRO prepares for its maiden human spaceflight in 2027.Shukla, who spent the past year in the US training for the Axiom-4 mission to the ISS, is expected to meet Prime Minister Narendra Modi before heading to his hometown, Lucknow.He will return to Delhi to participate in the National Space Day celebrations on August 22-23.Shukla shared a smiling photograph of himself on an aeroplane on Instagram, captioning it that he was filled with mixed emotions leaving the US and was excited to return to India to share his journey with everyone back home.“As I sit on the plane to come back to India, I have a mix of emotions running through my heart. I feel sad leaving a fantastic group of people behind who were my friends and family for the past one year during this mission. I am also excited about meeting all my friends, family and everyone in the country for the first time post mission. I guess this is what life is — everything all at once,” Shukla said in the post.“Having received incredible love and support from everyone during and after the mission, I can’t wait to come back to India to share my experiences with all of you. Goodbyes are hard but we need to keep moving in life. As my commander Peggy Whitson fondly says, ‘the only constant in spaceflight is change’. I believe that applies to life as well,” he said.Shukla also added, “I guess at the end of the day -‘Yun hi chala chal rahi – jeevan gaadi hai samay pahiya’,” recalling the song from the Bollywood movie Swades that was on his playlist just before he embarked on the Axiom-4 mission to the ISS on June 25 from the US.Astronaut Shubhanshu Shukla and his backup, Prashanth Nair, participated in the Independence Day celebrations at the Indian Consulate in Houston on Friday.Meanwhile, addressing the 79th Independence Day celebrations at the Red Fort, Prime Minister Narendra Modi highlighted India’s plans to develop its own space station and noted that Group Captain Shubhanshu Shukla has recently returned from a successful space mission.“Our Group Captain Shubhanshu Shukla has returned from the space station. In the coming days, he is returning to India,” Modi had said.Shubhanshu Shukla was part of the Axiom-4 private space mission, which lifted off from Florida on June 25 and docked at the International Space Station (ISS) on June 26.
