KalamSat: World’s Lightest & Smallest Satellite

World's Lightest & Smallest Satellite

NASA scientists have been unable to create the smallest satellite ever until now.. Indians once again made history by designing and building world’s smallest and lightest satellite on behalf of ‘Space Kidz India’, a Research Organization based on Chennai for children. Kalamsat is the brainchild of Rifath Sharook, an 18-year-old boy, from Tamil Nadu’s Pallapatti town, India.  Others on the team include Tanishq Dwivedi (flight engineer), Vinay S Bhardwaj (design engineer), Yagna Sai (lead technician), Mohammed Abdul Kashif (lead engineer) and Gobi Nath (biologist). For the past four years, these young minds have been working on rocket and space technology under the mentorship of Chennai-based Srimathy Kesan, the founder and chief executive officer of Space Kidz India.

How Zero G Planes Fly???


If you ever wished for weightlessness like astronauts, here is an easy way to feel it… Get into a Zero Gravity Plane. Zero Gravity Planes performs parabolic arcs to create a weightless environment allowing you to float, flip and soar as if you were in space. Parabolic flight or zero gravity flight is an aerobatic maneuver performed by an airplane that enables brief (15-25 sec) periods of near-zero-gravity. Astronauts feel weightless because their space shuttle is in a state of continuous free fall to the earth. If an astronaut on the space station drops a pen, it doesn’t look like it’s falling. That’s because they’re all falling together: the pen, the astronaut and the station. But they’re not falling towards Earth, they’re falling around it. Because they’re all falling at the same rate, objects inside of the station appear to float in a state we call “zero gravity” (0g), or more accurately microgravity (1×10-6g). Objects in a state of free fall are said to be weightless. The object’s mass is the same, but it would mark “0” on a scale. Eventhough your mass stays the same, weight varies depending on whether you are on Earth, the moon or in orbit. Gravitational force is a measurement of the acceleration due to gravity that causes weight. Zero gravity is a condition of weightlessness referring to the absence of a gravitational force (g-force or Gs). Continue reading “How Zero G Planes Fly???”
