That's how Ross' got here, we came from the Ross Star System, landed on Ross Island, in the Ross Sea, than migrated to Ross County Scotland... Naw I am just kidding, we are the Race of the Priest, those that Fall from Apple Cross (in Wester Ross), and are Decendants of the Once War Masters of Scotland, the Chiefs of the Great Clan Ross, the Earls of Ross, 1st which being Fearchar the Son of the Priest! And we just like naming stuff after ourselves, and if you are not careful Wilbur will Buy Yee Up! And you will be called, "Ross Quicktake"....

[@felix920]

How to stop?

[@Anarchy_420]

I think we should build a Lens Satellite that focuses the Sun onto The Solar Sails! This would certainly boost the speed and could even change direction if you change the location of Lens Satellite the beam will also be redirected causing the Solar Sail Spacecraft to change direction! This will also essentially be an unlimited energy source ;)

[@Makoto778]

Attempts at solar sailing went as early as Mariner 4, which featured solar vanes for orientation. Solar sailing/Solar pressure would play major parts in other missions like Kepler, Hayabusa, Messenger, in addition to purpose designed solar sail spacecraft. Solar pressure pressure can even be used to determine the difference between a dead spacecraft and asteriods (look up 2020 SO, now determined to be spacejunk rather than a small asteroid).

NASA confirmed that the EM drive doesn't work sadly

[@voidvector]

There is no theoretical basis for EmDrive, so it is Dead On Arrival by modern scientific standards. What this means is: 1) If it is allowed by existing theory, you make a computer simulation w/full physics laws, and show how it works in simulation 2) If it is a new phenomenon not captured by existing theories, you collect data to show existing law is wrong under some condition Instead EmDrive is like - I have this oddly shaped blackbox that I promise can do X, I need scientists and funding to help me proof it can do X.

11:53 No, Alpha Centauri is 4 light years away. So, not accounting for the long time it would take to accelerate and reach maximum speed, nor accounting for the deceleration effect as it nears its destination, it would take 40+ years, not "20 years".

Micro asteroids make micro holes. Webb telescope survived them. Spinning the whole satellite is going to take more energy than proven deploying techniques like ones used to deploy solar cells. Rocket engines and ion engines are mechanical parts too and more complicated than deploying solar sails. Solar sails are broad band reflectors, but are thin and some of the solar wind will go thru them. You know that sun spots disrupt satellites. I think the will want to avoid Corrona Mass Ejections to protect the electrons on the satellite.

[@tacticalpoet]

[@felix920]

@@ms-fk6eb I don't know if it's that easy. I suppose that the energy flowing in space has currents like on earth. Big stars produce more energy. Of course you can't stop using the sail if energy is pushing you from behind. Not to mention that at some point you go at really high speeds and decelerating relying on an invisible energy is like trying to stop a bullet by blowing on it.

[@fungidragon7494]

[@stephenjacks8196]

So what about Solar Wind, mostly protons, with momentum higher than sunlight.

[@Nehmo]

1:08 "just like a sailboat uses the wind..." But there is a substantial difference between the 2 methods of power. A wind sail on a boat uses the water resistance at an angle with the wind to force the boat in a resultant (perhaps "tacked" is a term) direction. You can't do that with a spacecraft. The angle of the "sails" on a spacecraft only makes them more or less "visible" to the sunlight. The spacecraft can only get sunlight trust in one direction - away from the sun.

[@williamchamberlain2263]

Great information. Not quite the same as sailing though; as I understand it modern sailing generates a lot of the force from aerodynamics rather than deflection, allowing ships to sail a lot closer to the wind than in the wooden warship era and earlier.

[@Aurumk1]

Make one side transparent and bounce the rest of the particles off the insides till their heat can be absorbed by phosphor coatings. This will emit light when passed through a gas, or make is so that the solar sail can be transparent possibly with a vanadium dioxide which allows light through up to a certain temperature or possibly liquid crystal but that seems to not survive space all that well. But also the phosphor coatings absorb heat and emit light so perovskite solar cells can be attached and wont be damaged. Then its a hybrid as well as maybe adding some magnets to it and some arms so it can move flexibily and catch the most solar wind.

[@peterthornton8520]

Changing the subject somewhat, could the fact that the earth over the past few years has started to rotate slightly faster (1.7 milliseconds per year currently) have something to do with the suns rays hitting more buildings etc than in the past causing the rotation rate increasing? No question is a dumb question.

[@theOrionsarms]

Small changes in rotation speed of the earth are caused by tidal forces of the sun and moon, and changes in circulation of the water in the earth oceans and under crust magma.

[@danielmisgana2672]

As technology progresses, we go back to our roots. And to places we’ve never been.

[@htopherollem649]

is the sail harnessing light or the solar wind, and if light has force then does it not have mass? if it does wouldn't that prevent going lightspeed, for doesn't mass increase as something with mass approaches lightspeed

[@fungidragon7494]

The sale is using light to accelerate itself and the light that is using is around the size of an atom so no it doesn't have mass

[@TheModeler99]

No, photons don't have mass but they have Energy in the form of momentum, which they transfer to the sail. The sail will gain speed but will never reach light speed.

@@sethdaboss245 a craft consistently being bombarded with a powerful beam of photons from a Mirror/Lens Satellite would in turn definitely have the potential for storing emensly large amounts of energy! The craft would then use that energy to decelerate! Remember we're dealing with the infinite energy source of the Sun being focused into a powerful beam! The only limiting factors are how much energy could we store from such power and the power would obviously decrease the further you get from the Sun! Which happens anyway with Solar Sails.

[@mrbaab5932]

​@@sethdaboss245 That is similar to reaction wheels on satellites now that slow down the rocket thrusts foe positioning.

[@mrbaab5932]

Why? Just make the sail bigger. As the lens and sail move apart the focused beam diverges. Also the lens is going to be orbiting the earth and moving with respect to the satellite. Draw some pictures over a few month spend. Also the lens would have rotate constantly as it rotates around the earth.

[@Anarchy_420]

@@mrbaab5932 some problems could be solved by moving its orbit into one similar to the JWST, however it would then take a bit longer as the craft would have to travel to its "orbital launch site"/Lens Satellite. Mirrors would also work!

[@Jaysin999]

Wouldnt this be dangerous if the sails got too close to a planets gravitational pull?? Also, wat if the sails get ripped by flying debris albeit asteroids and or any junk us humans have in space?? Would that factor into producing a much stronger but still thin sail??

last question: the tensile strenght of the material?

[@gargamelandrudmila8078]

In order to accelerate the probe via a solar grav assist without getting too close to the sun all one needs is to have a Sabo architecture. Sabo's are used in Tank artillery to increase the velocity of the armor piercing round. The round has two parts : 1- a heavy detachable part of the round. When the tank fires the round the Sabo will detach releasing the much lighter spear tip. Momentum increases with the square of the velocity of an object in motion. Momentum transfers to the lighter spear tip. This momentum transfer results in an increase of the lighter spear tip. The mass of the Sabo and tip in this case get a higher gav assist due to the increased mass of the Sabo and prob. 2: the spear tip will be the probe in this case, whilst the Sabo part can detach and burn up in the suns atmosphere. The above will ensure that the probe has the momentum and velocity to go anywhere in the solar system. I would still advocate for the probe to carry some small amount of propellant and use an iron drive to speed things up a bit or indeed slow down a probe to be able to insert into planetary orbits. I think the Sabo architecture, with multiple solar sails and ion drives will a very flexible solution andcan be built cost effectively to go anywhere in the solar system relatively quickly. This would be vital and a great opportunity to monitor and probe the many moons of Saturn and Jupiter.

[@fungidragon7494]

They could use the solar panels that are on the ship and a propeller that uses electricity to propel itself but it doesn't need that because of the Solar sail

[@mrbaab5932]

Wrong, the energy increases as the square of the velocity not the momentum. The purpose of the outer light weight housing of the shell is just to guide it down the barrel and nothing else. This is the same as using a big rocket 🚀 to launch a small light weight satellite so that it gets a higher speed.

how can you solar sail towards the sun? It makes sense that you can sail into the wind, but in that case, you have water that forces the boat to travel in the direction it's pointing in. When you are in space, there is nothing to keep the solar sail on track, so how does it work?

What's wild is if that probe ever makes it to alpha centauri, it will be 4.3 yrs before any of the pictures it takes make it back to us. Hopefully it could be autonomous enough to decide what to take pictures of on its own cause we won't be able to make any adjustments due to the extreme lag

A spacecraft with a solar sail and nuclear thrusters is the next step when it comes to space travel since chemical rockets are too slow. Its the easiest way to travel somewhere close to the speed of light and the technology for this already exists. My prediction is that when the mars base is established by SpaceX this technology will later be used. Since the trip to mars takes about 7 months and we would need to send cargo as quick as possible to help the colony grow this would be the best method to get there quickly. Then we would start getting better with this method and will use it to travel further even beyond the solar system.
