National Balloon Facility contains a complete balloon manufacturing facility. The institute conducts balloon-based scientific experiments in X-ray and Infrared Astronomy, and in Aeronomy. Balloons from this facility are launched twice in a year, i.e. in summer and winter. NBF also regularly monitors and analyses local weather at tropospheric and stratospheric altitudes, required for making decisions about balloon launches. Under the High Altitude Balloon Development Project, a 61,000m³ indigenously developed balloon penetrated into the Mesosphere on 7 January 2014, for the first time in India. Until that time, only balloons from USA and Japan had accomplished this feat. National Balloon Facility The National Balloon
