• On 21st June 2017, India once again broke a global space record by launching the world’s lightest satellite weighing a mere 64 grams, called Kalamsat.
  • It was designed and developed not by professional space scientists and engineers, but by 18-year-old Tamil Nadu student Rifath Sharook and his team.
  • The tiny satellite, named after Abdul Kalam, was flown by a Nasa sounding rocket and the lift-off was from the space agency’s Wallop Island facility around 3pm (IST).
  • Kalam had his training in the sounding rocket programme at Wallops Island in the ’60s. Kalamsat was the only Indian payload in the mission.
  • Mission director Srimathy Kesan announced total flight time of the rocket was 240 minutes and the satellite, assembled at her T.Nagar residence in Chennai, separated from the rocket 125 minutes after lift-off.
  • Kalamsat fell into the sea for safe landing.
  • It will be recovered and Nasa will be sending it back to India for decoding the data.
  • The previous Nasa mission from Wallops got postponed because of weather and India was able to launch successfully today.
  • This one-of-its kind satellite, which can be held in one’s palm is a 3.8cm cube and its structure is fully 3-D printed with reinforced carbon fibre polymer.
  • It is equipped with a nano Geiger Muller counter which will measure radiation in space.
  • It is the only cube to be converted into a satellite in this mission.
