Mission Purpose rsquo lsquo Breakthrough Starshot rsquo and lsquo Sprites rsquo were recently seen i...........

Explanation:

Starshot is a comprehensive space program launched under the US $100 million Breakthrough Initiatives, announced by Yuri Milner and Stephen Hawking to develop and launch practical interstellar space missions.
The program aims to demonstrate proof of concept for light-propelled spacecraft that could fly at 20 per cent of lightspeed.
Its main objective is to send one-gram chips to star systems beyond the solar system in search of extraterrestrial intelligence.
Mission Purpose was designed to test the performance of the ‘Sprites’ (tiniest satellite) electronics when in orbit.
It will also explore the concept of solar sail propulsion in which spacecraft can be powered using only the sun’s radiation.
Sprites have been developed by researchers at Cornell University. Each of the mini Sprite spacecrafts are built on a single 3.5*3.5 cm circuit board. They weigh just four grams each. These tiny satellites also mark the next step in the field of spacecraft miniaturization that can contribute to the development of centimeter and gram-scale StarChips envisioned under the Breakthrough Starshot project.
