LightSail spacecraft revives
The LightSail has deployed its solar sails after coming across some small issues. After solving these problems, the mission has moved further.
LightSail was launched nearly 40 years after Carl Sagan, a science fiction genius, presented his thoughts on a spacecraft that could sail by solar rays.
The Planetary Society is heading the project; Bill Nye (the Science Guy) is said to be its CEO. After finding out a software glitch that made the LightSail unresponsive and unable to return data to earth, the ground team tried to solve the problem.
It was found that the glitch was associated with the LightSail's solar-powered batteries. A unique 'ping-pong' effect was there that was created by levels of sunlight, which were too low in the earth's shadow and too high in direct sunlight; it led to battery instability.
After level of batteries was proved to be stable and charging, the ground control team tried to carry out a command sequence to open up the sails, however it didn't work. When it was tried for another time, the motor that deploys the sails started operating.
The LightSail is now flying and people can see it next time during its flyby. The Planetary Society's Mission Control could be checked to observe when the LightSail will be flying. It can reveal the best time to observe it on the basis of one's present location.
The Planetary Society said, "Look for flyovers that occur around dawn and dusk. The best time to see any spacecraft-including LightSail-is when you are standing in Earth's shadow but the spacecraft is still illuminated by sunlight".
