Astronaut Sunita Williams is celebrating her 59th birthday in space on September 19, with a special tribute organized by Saregama featuring prominent Indian celebrities. The tribute includes a rendition of the classic birthday song 'Baar Baar Din Yeh Aaye,' sung by stars such as Karan Johar, Sonu Nigam, and Shaan, inviting fans to join in with the hashtag #HappyBirthdaySunita. Williams' mission, expected to last only seven days, has now been extended until February 2025 due to technical issues with her spacecraft. The initiative has garnered widespread participation, with over 700 schools across India also joining in to create birthday cards and sing for her. Vikram Mehra from Saregama emphasized the collective love and admiration for Williams, stating that 1.5 billion Indians are celebrating her special day. The heartfelt messages and performances highlight her role as an inspiration in science and space exploration.
