- On June 25 in SpaceX rocket commitment 24 satellites run in & # 39; an earth, including the first & # 39; naval ship & # 39; worldwide space travel, which is only driven by sunlight.
- The space called LightSail 2, serves as an experiment that could change how & # 39; t auto & # 39; s driving themselves through space.
- After almost a month in the job, LightSail 2 is turning its signature today. Here's how to see if you can.
- The Planetary Society, the group behind LightSail 2, says the technology could ultimately help space travel reach interstellar trips.

All spaceships come with a maturity date: they can only travel until fuel is boarded.
This is one of the biggest obstacles that we have in exploring deep space.
But an experiment conducted by the Planetary Society can be a step towards tackling that problem. The group launched satellite with the name LightSail 2 on June 25; It has been designed to be the first spacecraft to be sent only by sunlight.
Today, LightSail 2 is rated to unlock its massive solar seal at 2:22 pm. ET (with a backup time of 4:07 pm ET). The Planetary Society will stream the sail's live, and you can view it through the embed below. All told, the unfurling should last about 45 minutes.
A sail driven by sunlight
LightSail 2 has linked the last month to a world. It round in & # 39; space on board a Falcon Heavy rocket from SpaceX, and scientists at Planetary Society has spent time since necessary hardware and software tests to ensure the satellite works well.

The apprentice was delayed for about two weeks, because the $ 7 million car had problems with its height control system. But now LightSail 2 is approved for sun-sailing.
"It's a game switch," said Bill Nye, head of the Planetary Society, about sun-sailing technology in a video. He added: "Perhaps we can sail one day to another star one day in the future."

How LightSail 2 works
LightSail 2's four triangular sails seem to shine water-borne sails into shape and function. They are designed to merge to form one of 344 square foot sails, and are made in the front of Mylar, a tri-resistant, highly reflective fabric that is thinner than a human hair.
Once completely unfurled, LightSail 2 & # 39; s mind seal will be about the size of a boxing ring. It should be visible about a year from the surface of the earth with the naked eye, say researchers.
A spacecraft that uses a sun seal has an almost unlimited power supply, pushing it continuously through the space by the pressure of sunlight: As a light reflection of the sail, the momentum delivers to the sail.
This works to & # 39; the sunlight consists of small particles called photons, which have no mass but gain momentum when they spit out of the sun. Each photon's individual momentum is minuscule, but the collective push is (theoretical) enough to move a solar sail.
To effectively utilize that power, LightSail 2 is designed to change its orientation based on where the sun is. Rigid bombs keep the sails out, and the spacecraft uses magnetometers to read changes in the magnetic field of the earth. Then, using a series of gyros and a momentum wheel, LightSail 2 would be able to orientate itself around it.
During each job around the globe, LightSail 2 should make two 90-degree turns of its sunscreen: It would be & # 39; the sun declines (as compared to sailing lessons) as the craft progresses, then be perpendicular to the sun as it moves to the light (as much as a sailboat approach).
Shoved in another cosmos
Newly said he is not sure exactly what will happen to the sun seal after it is used.
"Will it shift like a square ship?" he asked in a press conference in June. "Will it take a nice curve like a racing? Will it be something?"
After today's scientists would be able to answer these questions.
Ultimately, technology for solar-sailing technology would enable researchers at the earth to maneuver a spaceship as skippers send sailboats, and the rays of & # 39; utilize a mind to travel in every direction.
"Solar sails are just ideal," New said, "People have speculated about using sun sails as freighters to take material to Mars and so on."
By promoting this type of propulsion technology, spaceships can help one day reach space systems that are not currently accessible. This would help scientists to answer fundamental questions about our place in any cosmos.
"There are two questions that everyone says: Where have we all gone, and are we only in the universe? And if you want to answer those questions, you need to study space," New.
Part of that mission is to go to "asteroids, Mars and Europe," he added.
"And how do you get there? How will you send a spaceship, especially to an asteroid, to look for primary minerals?" he said. "Most likely, you will use a solar sail."
