and test how effective the sun is at pushing it. If it works, the technology could signal a breakthrough in space propulsion
photons from the sun will strike the sail and push it forwards, similar to how a sail On earth catches the wind.
This is because the force from the sun is constant, and there is no air resistance or friction holding the spacecraft back,
This will allow this second spacecraft to use the push from the sun to travel into the solar system.
A spacecraft using a solar sail could be placed in an orbit between Earth and the sun,
where it could remain in place without falling into the sun thanks to the push it receives,
known as tation keepingsuch a spacecraft could be used to either observe the sun in detail, or to look at Earth and track asteroids near the planet.
The idea for a spacecraft to be equipped with a solar sail to use the solar wind for propulsion was described by the late astrophysicist Carl Sagan four decades ago. ecause it has a constant acceleration,
it can get you around the inner part of the solar system a lot faster...than the usual sorts of rocket propulsion, he said in a 1976 broadcast of the Tonight show with Jonny Carson.
but in future the technology could be used for missions to the moon and other planets in the solar system. ith solar sailing,
