Small revolutionary spacecraft glides on sunlight in orbit around Earth



The congested spacecraft successfully orbits the Earth with only sunlight that can cover 6 million miles per day.

Lightsell 2 was launched by the Planetary Society, a space advocacy group, in June with its revolutionary mirror trip.

On July 24, small crafts – which are only 10 x 10 x 30 cm. Measures – deployed its reflective journey of 32 square meters that changed the shape of its orbit at its farthest point (apogee) about 2 km.

The mission team has confirmed that the increase in apogee is only attributable to solar boating, meaning that Lightsel 2 has successfully completed its primary goal of "flight by light".

The Express reports that the voyage became the first country to build a solar sailboat and used energy from the sun to the Earth's orbit.

That's how it works

Although photons of light have no mass, they carry energy and this means that they have momentum.

A reflective solar vessel captures that speed and transfers it to a spacecraft, just as a sailing ship captures motion from the wind.

The small spacecraft-powered sunlight was driven by hoisting its mirrored sails, and the research used thin plastic sheets to gain momentum from the sun.

Often the spacecraft was capable of maneuvering without the need for fuel or engines, and larger versions could also travel planets.


Game Switcher

Bruce Bates Lightsell Program Manager and Chief Scientist of the Planetary Society .The scientist praised the groundbreaking mission.

Mr Bates said: “We are thrilled to announce mission success for Lightsell 2.

"Our criteria was to demonstrate controlled solar sailing in CubeSat by using the sun's light pressure to change the spacecraft's orbit, which has never happened before.

"I'm very proud of this team. It's been a long way and we did it. "

Leading scientist. Bill Nye, CEO of the Scientific and Planetary Society, said the mission was a "game-changer" for further game research.

He said: "For the Planetary Society, it's been several decades since this moment happened.

"Carl Sagan talked about solar boating when I was in his class in 1977. But Johnny Kepler found that the comet tail must have been created by energy radiation from the sun, at least 1607.

"Lightsell 2 Mission is a game-changer for spaceflight and space exploration."

LightSail 2 is a crowdfunded mission and includes donations from 50,000 people around the world.

The Jennifer von Planetary Society CEO said the mission could be a "paradigm shift" to get more people involved in the space mission.

Mrs Vaughan said: “Lightsell 2 proves the power of public support.

"This moment could mark a shift in patterns that opens up space exploration for more players.

"It amazes me how many, 000,000 people came together to fly the solar ride.

“Imagine if that number were 500,000 or 5 million. It is an exciting concept. "

In a statement on the Planetary Society Twitter account, the team wrote: "LightSail 2 is the highest performing solar sail ever and is 100% crowded by our members and supporters!"

Lightsail 2 has a limited lifespan and is destroyed.

The spacecraft will eventually crash into the sun and burn as it continues its orbit.

This technology follows Lightsell 1 which manages very little orbit on the same approach.

However, LightSail is not the first single-spaced spacecraft to reach the other side of the sun.

Japan's Icaros, carrying a Mitsubishi H-2 rocket, made the trip in May 2010.

Icaros was assisted in the journey to Jupiter, where he landed, after a three-year journey through a 20-meter journey.

Reporting on the mission, Japan's space agency said, "During the international cruise, there will be a world-class solar powered craft employing both photon propulsion and thin-film solar power production."
