Space Technology Students' Society, or spAts, is the official student body under Kalpana Chawla Space Technology Cell, IIT Kharagpur. Established in 2008 by a small group of young and ambitious undergraduate students, spAts had humble beginnings. A small club founded as a congregation of students with a common interest called space, spAts started as an ordinary student-run society with big ambitions. Since its inception, the society has seen multiple changes. From what used to be a regular space discussion forum, spAts evolved into a professionally run society that hosts many events, along with the first and largest space technology fest in India, the National Students' Space Challenge.
The National Students' Space Challenge (NSSC) is the centrepiece of spAts. As the name suggests, NSSC is a national-level fest dedicated solely towards space and space technology. The fest began in 2011 when the society decided to independently host a fest to provide a platform to the aspiring engineers and scientists of India who were only waiting for an opportunity to showcase their talents. Various other events, such as autonomous and manual bot-making, space quizzes, case studies and astrophotography, have been added over the years. Besides the events, the National Students' Space Challenge is famous for its supremely successful guest lectures, exhibitions and workshops.
