YOUTHSAT is a joint Indo-Russian stellar and atmospheric satellite mission with the participation of students from Universities at graduate, post graduate and research scholar level. With a lift-off mass of 92 kg, Youthsat is a mini satellite and the second in the Indian Mini Satellite (IMS) series. Youthsat mission intends to investigate the relationship between solar variability and thermosphere-Ionosphere changes. The satellite carries three payloads, of which two are Indian and one Russian. Together, they form a unique and comprehensive package of experiments for the investigation of the composition, energetics and dynamics of earth's upper atmosphere.
The Indian payloads are:
- RaBIT (Radio Beacon for Ionospheric Tomography)- For mapping Total Electron Content (TEC) of the Ionosphere.
- LiVHySI (Limb Viewing Hyper Spectral Imager) - To perform airglow measurements of the Earth's upper atmosphere (80- 600 km) in 450-950 nm.
The Russian payload
SOLRAD - To study temporal and spectral parameters of solar flare X and gamma ray fluxes as well as charge particles in the earth polar cap regions.
