When will we reach the Moon, Mars, Jupiter, another star and another galaxy...

but that was a very old probe with tiny thrusters just lots of fancy aerobatics to gain speed.

If we built the Orion ship it's estimated to take only 40-50 years to reach the nearest star.

Project Longshot would carry a separate 300kW power plant for the shipboard systems, and reach 30,000,000 mph. So a hundred years. We haven't sent any probes out to explore other star systems, voyager et all were for exploring our star system. It's technically possible for sure.
 
You made a minor mistake there and missed a step. You cannot slow down your speed and get to the destination faster. 99% has to take longer than 25,000 years not less. EDIT: Plus just to be awkward which edge of the galaxy is 25,000 light years away? isn’t one edge much closer to use then the other edge.

Agreed on the first point. My bad. Lets call it 25,500 years then :D

On the second point I was assuming the closest edge to us.

hopefully though voyagers power will last long enough to send us a lot of information about what happens as you pass out of the solar sytem and though the boundary.

That would be a bonus, well beyond the mission parameters. Pretty sure we could launch something simple and relatively cheap with a solar sail that would get out of the solar system before voyager did if we thought there was that much to learn.

I'd suspect it's very cold, and very empty outside the Solar System with big blasts of radiation from local Pulsars and such.
 
AcidHell2 said “But it wouldn't be 25,500 years. See my other post with the screen shot explaining it.”
It would be from the prospective of the people on Earth. By the time you reach the destination Earth any everyone would be 25,500 years older. Sure you might not have aged 25,500’s years but effectively you have lost 25,500 years.

It’s kind of like taking a trip that appears to take 1 week. But on the outside 50years pass for everyone else. Sure only 1 week passed for you, but all your loved ones and everyone you know died of old age or got very old.

EDIT: Or to put it another way, if you took the trip to the edge and back to Earth you would find 50,000 years of history has gone by.

Which isn't a problem, as you aren't going to be doing return trips. It's also not what neodude is saying, he is saying it will take you that long to reach it, when in fact it's closer to 80 years.

what could be a problem though is during those 25k years they advance technology to the point they find a way around the problem and when you get there ready to set up the first ever colony of man, it's already a 10,000 year old colony with billions of people :p


but it is a problem for probes and scientific exploration, waiting 5 years after they get there for data or 10 years to give a "pan down" command and to get the image back :p
 
Which is where quantum entanglement could be used, if they could master it.

Now how would that work with relativity.

To Ganymede and Titan,
Yes Sir, I been around,
But there ain't no place,
In the whole of space,
Like that good ol' Titan town.

Oh, Lunar City Seven,
You're my idea of heaven,
Out of ten you score eleven,
You good ol' Titan town.
 
I will point you in the direction of a 6 part documentary called When We Left Earth.
If it is a hoax the space films they were showing were some of the best CGI I've ever seen (before CGI was invented) and the 'actors' were all worthy of an Oscar a thousand times over.
Just do a proper bit of research such as:
Why did America's most deadly rival Russia accept that America landed on the moon?
What did America send into space so that 1000s upon 1000s of Ham Radio enthusiasts could track it?

You know you shouldn't give numpties who think the lunar landings were fake a single moment of your time! 2 minutes on google would answer every conspiracy raised about the matter.

The people who endorse such thinking are in reality either wanting attention or help...
 
Well if you actually believe we landed on the moon in the first place that is? I don't so space travel is far far away.......

How can this kind of opinion still be possessed by people? I don't understand it....

How do you suppose we got stuff into orbit? Go and watch the highlights of the Space Shuttle mission to the ISS that is happening RIGHT NOW, if you watch those videos thinking they're fake then clearly you have issues. Getting into orbit is the hardest part, you can buy a telescope and look at the ISS as it orbits overhead from your garden!!. Or have lizard men put a tiny ISS pictures in all telescopes?

Getting to the Moon is easy in comparison :rolleyes:

With regards to the OP:

- A human lands on the Moon again: Depends upon the validation of profitable resources on the Moon. If that happens, then 2020. If not, probably never again.
- A human lands on Mars: Would have been within 20 years if the NASA project hadn't been scrapped. Realistically now 30 to 40 years
- A human reaches Jupiter: After Mars it's gets difficult. Maybe within 100 years
- A probe or human reaches another star: New propulsion technology has a long way to go and needs money no one has at the moment. 3.3% of Lightspeed will still take 120 years or more to reach Alpha Centuri
- A probe or human reaches another galaxy: Quite a long way. Laws of Physics get in the way to do it on a realistic time scale

No. We are about 25,000 light years from the edge of the galaxy. At 99% speed of light it would take 99% of 25,000 years to get there (24,750 years). The only difference relativity would make is that to an observer on Earth it would seem to take a lot longer. If your 1 hour = 1 day relationship is accurate it would appear to an observer on earth that the journey would take 594,000 years.

No - travelling 25,000 years at 99% the speed of light would take 1% longer than 25,000 (not 99% of 25,000) years from the point of view of the observers back on earth. The people travelling at 99% the speed of light would experience a shorter duration, though I get about 3,500 years - to do the trip in 80 years as suggested requires about 99.9995% of the speed of light!

I would like to think we landed on the moon but still aren’t a 100%. Just my main reason is why has it taken us so long to get back..... and no the recession wasn’t the issue :p.

I guess once we have a telescope that can see the surface crystal clear we should be able to see the landing sites.... even if that’s possible might be a silly question.


Tin hat time

A Set, A Camera and Photoshop.

and Lunar rocks eh,

but seriously, im feeling Argumentative, but i still dont believe anything i dont see with my own eyes, in reason ofc

YOU, with the right equipment, can FIRE A LASER at the specific place a MAN left a reflector ON THE MOON and it can be recorded bouncing back.

It is scientific proof that man went to the moon.

honestly, teenagers.

"It really is that simple. If we want to travel into the future, we just need to go fast. Really fast. And I think the only way we're ever likely to do that is by going into space. The fastest manned vehicle in history was Apollo 10. It reached 25,000mph. But to travel in time we'll have to go more than 2,000 times faster. And to do that we'd need a much bigger ship, a truly enormous machine. The ship would have to be big enough to carry a huge amount of fuel, enough to accelerate it to nearly the speed of light. Getting to just beneath the cosmic speed limit would require six whole years at full power.

"The initial acceleration would be gentle because the ship would be so big and heavy. But gradually it would pick up speed and soon would be covering massive distances. In one week it would have reached the outer planets. After two years it would reach half-light speed and be far outside our solar system. Two years later it would be travelling at 90 per cent of the speed of light. Around 30 trillion miles away from Earth, and four years after launch, the ship would begin to travel in time. For every hour of time on the ship, two would pass on Earth. A similar situation to the spaceship that orbited the massive black hole.\

After another two years of full thrust the ship would reach its top speed, 99 per cent of the speed of light. "At this speed, a single day on board is a whole year of Earth time. Our ship would be truly flying into the future.*

"The slowing of time has another benefit. It means we could, in theory, travel extraordinary distances within one lifetime. A trip to the edge of the galaxy would take just 80 years. But the real wonder of our journey is that it reveals just how strange the universe is. It's a universe where time runs at different rates in different places. Where tiny wormholes exist all around us. And where, ultimately, we might use our understanding of physics to become true voyagers through the fourth dimension

LOL - you would hope they'd have the courtesy to pick the poor guy up on the way and give him a lift! :)

When (OK - if :() we have the super-duper FTL tech I wonder if we'll buzz around and collect all our old probes and stick them in museums? We could replace them with replicas maintaining the original trajectories to avoid upsetting the old folk who think we should leave them alone :).
