> best example > voyager 1 probe > picrel The Voyager 1 program was launched in 1977, and is now the farthest human-made object from Earth. It's currently about 21 billion kilometers away, or about 119 times the distance from Earth to the Sun. That’s about a third of the way to the nearest star, Proxima Centauri. At its current speed, it would take about 73,000 years to reach Proxima Centauri. The Voyager 1 spacecraft is about the size of a small car. It weighs about 825 kg (1,818 pounds), and is about 6.7 meters (22 feet) long. The probe is powered by radioactive plutonium-238, and has enough fuel to last until around 2025.
It is on a mission to explore the outer solar system and beyond. It has already made several important discoveries, including the first direct evidence of the existence of an interstellar magnetic field.
The Voyager 1 probe is currently travelling at a speed of about 17 kilometers per second.

How did they do it? How in the fuck did those crazy motherfuckers make this flimsy thing indestructable?! And why do they hide it? Because its alien tech?
I mean why did they possses this tech back then and now it's gone. Look a this moon shuttle. What type of magic technology is this? They hide something from us.
I'm doubtful you understand how space travel works. These things just got one big push early in their journey to go super fast in the inner solar system. This speed then slowly depletes as it travels, being held back by the solar systems gravity well. It's not flying there under its own power. One reason it will take so fucking long to get anywhere near that other star.

>launched in 1977 > third of the way to the nearest star, Proxima Centauri >it would take about 73,000 years to reach Proxima Centauri. I haven't researched interstellar travel. How does that make sense?
James Foster
NASA is a front to hide the real spacecraft. Red pill yourself on the ARV. Then ask yourself why they won't tell us what they've really found out there.
Also micrometeoroid densities go to fuckall as you head away from the sun.

>The probe is powered by radioactive plutonium-238, and has enough fuel to last until around 2025. There's your answer. Putting nuclear material in space is a huge violation of treaty. Also they always hide all nuclear shit like that. Also the US did begin designing a manned nuclear powered spaceship but buried that shit hard. This is more interesting. I can't confirm these calculations off the top of my head but it raises questions worth considering. >I mean why did they possess this tech back then and now it's gone. It's almost certainly not gone. They didn't admit it existed back then either, certainly not openly.
Lincoln Sullivan
Because space is fake and gay, we live in God`s Kingdom
it uses a radiothermal generator senpai. Any spacecraft that's going to travel into the outer solar system has to use one because solar panels suck mega dick once you get past like mars orbit because solar density falls off with the square of distance.
tl;dr this is common and not something to freak out about. the soviets did it all the time too.
Levi Murphy
it doesn't. 119 AU (distance earth to sun) is 0.00188172857 lightyears. the distance to proxima centauri is 4.246 lightyears.
Cooper Flores
1 AU (astronomical unit) is one time the distance from the earth to the sun

Today it is a violation, but it wasn't before, there were no treaties, no international laws. There was nothing secret nor hidden about it, it was simply a possibility and many programs exploited it. Now a lot of people look back on it and regret it's not longer possible.

Jackson Martinez
>Proxima Centauri lies at a distance of 39,900,000,000,000 kilometres, or 271,000 astronomical units, or 4.22 light years. It is slightly closer to Earth than Alpha Centauri A and Alpha Centauri B, which are 4.35 light years away. Bumping just because I'm learning something today. Yeah, Sputnix V had nuclear material onboard when it crashed into Earth if I recall. The point is more that any of this nuclear tech is under the DOE which has the most secrecy of any government agency. Even CIA shit is done under the DOE contracts.
Leo Martinez
How is it 1/3 the distance to the nearest star but still take 73000 more years to get there

it is not a third of the way, its barely left the solar system
Michael Green
>Why does NASA hide its technology from us? Because then we might ask them how the shit works and why it looks like it's made of tinfoil.
Liam Russell
Putting a nuclear weapon or something that could be used as a weapon is a violation, fissile material is not. RTG is very common in space missions.
The Orion project literally used nuclear bombs as propellant, completely different.
Nathaniel Wood
>384321004 yes. magic metals that are no longer available. appear visually and to the touch to be aluminum foil, but in reality, were ultrastrong and provided the same protection from radiation as 1.82 meters of lead.
Julian Diaz
what do you mean today it's a violation? the perseverance rover that landed on mars in 2021 has a similar nuclear powersource.(radioisotope thermoelectric generator is the technical term)
they don't hide it at all, its public knowledge that they use radioisotope thermoelectric generators. it's on their website and on wikipedia.. they just have a chunk of radioactive material decaying and they use the heat that it gives off.
Ethan Jones
21 billion kilometers is more like 0.0005% of the way there if I'm calculating this right.
Bentley Thomas
>An estimated 25 million meteoroids, micrometeoroids and other space debris enter Earth's atmosphere each day Cool, now calculate how much bigger the Earth is than the Voyager.

Joshua Sullivan
where is the whipple shield placed on the voyager1? D you have an image?
Owen Garcia
It is made of tinfoil tho. Its a whipple shield. At orbital velocity tinfoil is enough to vaporize a small impactor which can be stopped by successive layers Also reflective metal foils are the ideal insulation in a non convective environment like space.
