Solar sails represent one of the most elegant concepts in space exploration: using sunlight itself to propel spacecraft ...

CubeSats are becoming ever more popular, with about 2,400 total launched so far. However, the small size limits their options for fundamental space exploration technologies, including propulsion.

Meanwhile, a journey to the heliopause (the demarcation line for interstellar space where the sun’s magnetic forces cease to influence objects) could take between 4.2 and 5.3 years.

To achieve 20 percent of the speed of light (0.2 c), the Starshot nanocraft and sail would require a 100 Gigawatt (100 billion watts) laser array to push the sail for a sustained period of 10 minutes.
