Solar sails could shorten space travel time by thousands of years. By using the power of the sun, photons bounce against the sail and give it a push to propel the satellite to it's destination. NASA plans to test the solar sails to take a closer look at near earth asteroids.

New research paper from the Cool Worlds Lab about one the most exciting missions ever proposed, "Starshot". Starshot plans to send tiny probes to distant planets beyond our Solar System, the first true interstellar spacecraft. To do this within our lifetimes requires a very fast probe, reaching one-fifth the speed of light. That means Einstein's theory of special relativity starts to become important and so in our new paper, explained in the video, we figured out how much of a difference that makes... ::More about this Video:: ► David Kipping (2017), "Relativistic Light Sails": https://arxiv.org/abs/1704.04310 ► Live stream of the Breakthrough Discuss meeting at Stanford (04/20-04/21): https://www.facebook.com/BreakthroughPrize ► Breakthrough Initiatives website: https://breakthroughinitiatives.org ► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu ► Columbia University Department of Astronomy: http://www.astro.columbia.edu ► Background music by Thomas Bergersen "Final Frontier": http://www.thomasbergersen.com ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!! ヅ

It took the Voyager 1 spacecraft over three decades to leave the solar system (and scientists still aren’t sure when it did). We need a new method of propulsion that will transport spacecraft faster than ever before. NASA is one of a few agencies developing a new way to sail through space, on the power of the solar wind.

It’s going to be almost impossible to travel to another star, but a new idea was announced that might get us to a nearby star within our lifetime. How will it work?

Many of you said it was the most depressing episode I’ve ever done . The distance to Pluto is, on average, about 40 astronomical units. That’s 40 times the distance from the Sun to the Earth. And New Horizons, the fastest spacecraft traveling in the Solar System took about 10 years to make the journey. The distance to Alpha Centauri is about 277,000 astronomical units away (or 4.4 light-years). That’s about 7,000 times further than Pluto. New Horizons could make the journey, if you were willing to wait about 70,000 years. That’s about twice as long as you’d be willing to wait for Half Life 3. But my video clearly made an impact on a plucky team of rocket scientists, entrepreneurs and physicists, who have no room in their personal dictionary for the word “impossible”. Challenge accepted, they said to themselves. In early April, 2016, just 8 months after I said it was probably never going to happen, the billionaire Yuri Milner and famed physicist Stephen Hawking announced a strategy to send a spacecraft to another star within our lifetime. In your face Fraser, they said... in your face. The project will be called Breakthrough Starshot, and it’s led by Pete Worden, the former director of NASA’s AMES Research Center - the people working on a warp drive. The team announced that they’re spending $100 million to investigate the technology it’ll take to send a spacecraft to Alpha Centauri, making the trip in just 20 years. And by doing so, they might just revolutionize the way spacecraft travel around our own Solar System. So, what’s the plan? According to their announcement, the team is planning to create teeny tiny lightsail spacecraft, and accelerate them to 20% the speed of light using lasers. Yes, everything’s made better with lasers . We’ve talked about solar sails in the past, but the gist is that photons of light can impart momentum when they bounce off something. It’s not very much, but if you add a tremendous amount of photons, the impact can be significant. And because those photons are going the speed of light, the maximum speed for the spacecraft, in theory, is just shy of the speed of light (thanks relativity). You can get those photons from the Sun, but you can also get them from a directed laser beam, designed to fill the sails with photons, without actually melting the spacecraft. In the past, engineers have talked about solar sails that might be thousands of kilometers across, made of gossamer sheets of reflective fabric. Got that massive, complicated sail in your mind? Now think smaller. The Starshot spacecraft will measure just a few meters across, with a thickness of just a few atoms. The sail would then pull a microscopic payload of instruments. A tiny chip, capable of gathering data and transmitting information - these are called Starchips. Not even enough room for water bear crew quarters. With such a low mass, a powerful laser should be able to accelerate them to 20% the speed of light, almost instantly, making a trip to Alpha Centauri only take about 20 years. Since each Starshot might only cost a few dollars to make, the company could manufacture thousands and thousands, place them into orbit, and then start bugzapping them off to different stars. There are, of course, some massive engineering hurdles to overcome. The first is the density of the interstellar medium. Although it’s almost completely empty in between the stars, there are the occasional dust particles. Normally harmless, the Starshots would be smashing into them at 20% the speed of light, which would be catastrophic. The second problem is that this is a one-way trip. Once it’s going 20% the speed of light, there’s no way to slow the spacecraft down again (unless the Alpha Centaurans have a braking system in place). Just imagine the motion blur and targeting problems when you’re trying to take photos at relativistic speeds.

It's been a busy two months of testing for The Planetary Society's LightSail 2 spacecraft. Engineers spun the CubeSat like a record and shined flashlights in its electronic eyes in order to make sure everything goes according to plan when the solar sail heads into space. LightSail will soon be transported to Utah State University's Space Dynamics Laboratory, where it will be flooded with magnetic fields in order to calibrate the spacecraft's attitude control system. This short video showcases tests of the spacecraft's momentum wheel, gyroscopes, deployment motor and sun sensors.

Solar sail Solar sails (also called light sails or photon sails) are a form of spacecraft propulsion using the radiation pressure (also called solar pressure) from stars to push large ultra-thin mirrors to high speeds.Light sails could also be driven by energy beams to extend their range of operations, which is strictly beam sailing rather than solar sailing. =======Image-Copyright-Info======== License: Creative Commons Attribution-Share Alike 3.0 (CC BY-SA 3.0) LicenseLink: http://creativecommons.org/licenses/by-sa/3.0 Author-Info: Andrzej Mirecki Image Source: https://en.wikipedia.org/wiki/File:IKAROS_solar_sail.jpg =======Image-Copyright-Info======== -Video is targeted to blind users Attribution: Article text available under CC-BY-SA image source in video https://www.youtube.com/watch?v=R-InnipTxgs

In this time lapse, the Near-Earth Asteroid Scout (NEA Scout) CubeSat team rolls a half-scale prototype of the small satellite's solar sail in preparation for a deployment test. During its mission, NEA Scout will perform an approximate two-year cruise propelled by the solar sail to a target asteroid. A camera on the CubeSat will capture a series of low (50 cm/pixels) and high resolution (10 cm/pixels) images to determine global shape, spin rate, pole position, regional morphology, regolith properties, spectral class, and for local environment characterization.

When scientists are planning missions, they sometimes have to take into account the fact that the light from the Sun pushes on the spacecraft. But with solar sails, they can also use that pressure to propel the craft along. ---------- Dooblydoo thanks go to the following Patreon supporters -- we couldn't make SciShow without them!

But I don't want to hypothesise yet on what it means because I don't know yet what really happened". 15. Mid shot of experts at the computer monitor 16. Wide shot of experts STORYLINE A Russian attempt to launch a solar sail vehicle designed to be propelled by pressure from sunlight has failed again because the booster rocket suffered engine failure soon after it blasted into space, the state news agency RIA-Novosti reported. The launch was part of a joint Russian-U.S project attempting the first controlled flight of a solar sail. An unnamed official in Russia's Northern Fleet told the news agency early Wednesday that the engine failure occurred 83 seconds after the launch from a submerged Russian submarine in the northern Barents Sea at 1946 GMT on Tuesday. A spokeswoman for the Lavochkin institute involved in the project, told The Associated Press she could not confirm the information but said that if the engine had failed then the vehicle would have fallen back to Earth. Past attempts to unfold similar devices in space have failed. In 1999, Russia attempted a similar experiment with a sun-reflecting device, but the deployment mechanism jammed and the device burned up in the atmosphere. In 2001, Russia launched another such experiment, but the device failed to separate from the booster. The project involved Russia's Lavochkin research production institute and was financed by an organisation affiliated to the U.S. Planetary Society. During the first 45 minutes after launch, in two stages the solar sail was to have separated from the booster and then an engine still powering the device. But space officials lost all signals from the spacecraft. The spacecraft, called "Solar Sail", weighs about 110 kilograms (242 pounds) and is designed to go into an orbit more than 800 kilometres (500 miles) high. It is designed to be powered by eight 49.5-foot-long (15.1-meter-long) sail structures resembling the blades of a windmill. Each blade can be turned to reflect sunlight in different directions so that the craft can tack, much like a sailboat in the wind. The aim is for streams of solar energy particles to push a giant, reflecting sail through space the way wind propels sailboats across water. Solar sails are envisioned as a potential means for achieving interstellar flight in the future, allowing such spacecraft to gradually build up great velocity and cover large distances. Space-sail technology is something that existed solely in science-fiction novels a decade ago. Yet the reflective solar sail could power missions to the sun and beyond within a decade and NASA has invested about US$30 million in this field.

NASA recently announced further funding for a huge new solar sail spacecraft that could travel quickly across the solar system and beyond. Called HERTS, or Heliopause Electrostatic Rapid Transit System, the sail would launch on Earth as a relatively compact spacecraft, but once it reached a safe distance from earth, it would unfold its Mylar sails across wires extending a whopping 12 miles from the spacecraft's center! The sails would use photonic pressure from the Sun's solar wind for thrust. It is similar in many ways to the smaller LightSail launched recently by Bill Nye, based off designs by Carl Sagan.

Share on Facebook: http://on.fb.me/1GqkB3h One of the biggest challenges facing space exploration is propulsion. Our main go-to, rocket fuel, is heavy, expensive, and can easily run out during travel. Fortunately, the solution might come in the form of solar sails. The Planetary Society has already tested the solar sail deployment mechanism designed for Lightsail. The next step? Building a deep-space vehicle that uses solar sails as the primary means of propulsion. What sort of citizen-based science project would you most be interested in getting involved in?

Today (May 20, 2015) at 17:45 MSK. Bp. from Cape Canaveral will be launched rocket "Atlas V" with a lot of satellites, one of which would be unusual "LightSail A". This spacecraft uses an unusual way to travel in space, based on the action of the solar wind pressure. It is best suited for this purpose the mirror surface, so the solar sail could be bright for observers on Earth. Area solar sail "LightSail A" is 32 square meters. m, i.e. it will be a square with sides of about 6 meters - material "Mylar". Weight spacecraft of 5 kg.

In 1976, Carl Sagan appeared on The Tonight Show to talk about a crazy new idea: solar sailing. Nearly 40 years later, The Planetary Society is realizing this dream with a new spacecraft called LightSail designed to propel through space on beams of sunlight. http://sail.planetary.org Carson Footage Supplied Courtesy of Carson Entertainment Group Music by General Fuzz

The first of The Planetary Society's two LightSail spacecraft will ride to space aboard an Atlas V rocket in May 2015. The mission is a shakedown cruise designed to test out the CubeSat's critical systems. In 2016, the second LightSail spacecraft will piggyback into orbit aboard the first operational flight of SpaceX's new Falcon Heavy rocket for a full-fledged solar sailing demonstration.

HELIOS is an advanced solar sail concept being evaluated by NASA's Space Technology Mission Directorate (STMD). NASA's STMD rapidly develops, demonstrates, and infuses revolutionary, high-payoff technologies through transparent, collaborative partnerships, expanding the boundaries of the aerospace enterprise. http://www.nasa.gov/spacetech ____ From the video: NASA is designing a next-generation solar sail: HELIOS, or High-Performance Enabling Low-Cost Innovative Operational Heliogyro Solarsail. HELIOS will demonstrate a type of high performance solar sail called a heliogyro. The "sail" of the heliogyro consists of very long reflective membrane strips, or blades. Blades are rolled onto reels to simplify packaging and deployment. Sunlight reflecting on the blades creates thrust. No on-board fuel is required. HELIOS requires no additional structure to maintain its shape. This reduces weight and permits higher accelerations and shorter travel times to distant destinations. HELIOS also steers like a helicopter. Tilting each blade redirects the reflected sunlight and solar pressure. This can be used to change thrust, orientation relative to the Sun or spin rate. Cameras will capture the motion of the blades, sending proof of deployment to Earth, recording video to compare with computer models and communicating blade motion to the blade control system.

LightSail's solar sails deploy during spacecraft testing at Cal Poly San Luis Obispo on Sept. 23. For testing purposes, the sail booms were only extended to 90 percent of their full length. They were then incrementally extended so engineers could measure sail tension and record the correct number of deployment motor revolutions.

I'm Fraser Cain, and I'm a sailor. Well, okay, I've got a sailboat that I take out on the water when its warm and the weather's nice here on Vancouver Island. I think it's one of the reasons I absolutely love the idea of a solar sail. Here's how they work: Light is made up of photons. Even though they have no mass at rest, they have momentum when they're moving, well, light speed. When they reflect off a surface, like a mirror or a shiny piece of metal, they impart some of this momentum to that surface. This effect is negligible here on Earth, but out in space, with forces perfectly in balance, that additional momentum can really add up. A spacecraft flying to Mars gets pushed off course by several thousand kilometers because of light pressure from the Sun.If mission planners didn't compensate for this drift, their spacecraft would miss the planet, or even worse, crash into it. Even though the total amount of pressure per square meter on a solar sail is minuscule, it's constantly streaming from the Sun, and it's totally free....And propulsion that you don't have to carry with you is the best kind there is. This is more than just an idea. Solar sails have already been launched and deployed in space. The Japanese Ikaros satellite unfurled a 14-meter solar sail back in 2010. NASA launched its own Nanosail-D spacecraft in 2011. An even bigger solar sail, the Sunjammer, is planned for launch in 2014. The Planetary Society is working on a solar sail project as well. The closer to the Sun you are, the better they work. In fact, a solar sail would be an ideal vehicle to explore the regions of Mercury and Venus, since they receive so much radiation. But you're probably wondering how a solar sail could get down to those planets because light is streaming from the Sun in all directions. It's all about raising and lowering your orbit. If you want to raise your orbit around an object, all you have to do is speed up. And if you want to lower your orbit, you just need to slow down. A solar sail launched from Earth would start out with the same orbital velocity around the Sun as the Earth. To get into a higher orbit, it tilts the sail so that the light from the Sun speeds it up. And to get into a lower orbit, it tilts in the opposite direction, and the light from the Sun acts like a brake. A solar sail might even be the ideal spacecraft to make the journey to another star. An interstellar solar sail could lower its orbit so that it's just above the surface of the Sun. Then, it would unfurl the full sail and capture the most possible photons. A series of powerful laser beams would then target the sail and increase its velocity to a significant fraction of the speed of light. Of course, you'd need a solar sail thousands of kilometers across, made of a material thinner than a human hair, and lasers putting out more energy than all of humanity. The idea is still intriguing, even though it's well outside our current technology. Once this technology gets better tested, we'll to see many more missions employ solar sails as part of their propulsion system.

http://www.kickstarter.com/projects/aresinstituteinc/lunarsail-the-worlds-first-crowdsourced-solar-sail/ The primary objective of the LunarSail mission is to serve as a testbed for cubesat and solar sail operations beyond low Earth orbit and applications requiring cislunar or interplanetary rendezvous. It is a proposed cubesat mission intended to demonstrate practical application of solar sail technology for propulsion, trajectory/attitude control and rendezvous with another body in space. With LunarSail, we will take advantage of the cubesat platform to conduct a first of its kind mission to use a solar sail to send a spacecraft to the Moon and then utilize the sail's unique characteristics to navigate into lunar orbit. LunarSail is a different kind of space exploration mission. It is not a government project and while remaining open to - and in fact seeking - government-provided funding and assistance in finding a suitable launch opportunity, a substantial amount of our budget is being fulfilled via crowdfunding and private donations. Through crowdfunding, private citizens are able to donate any amount, and not just money but also labor, programming and ideas -becoming co-owners of the mission, stakeholders in its success. We are inviting creative people and the public to submit messages, artwork, music and short video clips that will be stored onboard the spacecraft in a reserved area of computer memory storage. By doing this, artists will be able to send their works into space and to the Moon and everyone will be able to send their messages into space. We plan to integrate social media outreach into the mission, in particular once the spacecraft is in space. In addition to radio, cameras and telemetry, we will use social media as another means of communicating to and from the spacecraft. We will integrate social media into the software and communications architecture and utilize it to facilitate interaction with the public.
