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

Closest star is about 50 light years away, so getting a probe there would only take 100 years, and thats just 1/2 light speed. Thats with current tech.

I'm really not sure where you pulled your facts apart from out of your ***.

The closest star is 4.2 light years away.

That is roughly 42 trillion kilometres. The current fastest man made object is the helios probe which travelled at 252,792 km/h or 0.000234 of the speed of light. This was mainly due to a highly elliptical orbit around the sun though.

Even if we take that speed as a set constant speed of a probe heading towards Proxima Centauri we can calculate that it would take 17,948 years to reach the star.

In order to reach half the speed of light the probe would have to be going at 150,000 km per second, over 2,100 times faster then the helios probe.

There is enough Helium-3 on the Moon to power Earth for many thousands of years and it's green power too! Never mind the amount of water on the moon or the fact it makes a great launch platform for getting out to the solar system.

Then there is the scientific advantages such as placing an observatory on the dark side of the Moon.

The moon is far, far from a waste of time.

Theres still so many problems preventing getting to Mars, never mind somewhere further. It’s a 2 year round trip which means 2 years of food, 2 years of water and 2 years of waste storage (although it has been suggested that human solid waste could be used as a radiation shield as it has better shielding properties than the stuff they currently use lol). Urine can be and is desalinated and filtered so that it can be re-consumed.

Someone needs to create some form of artificial mavity before long journeys can be considered though because of the devastating effect that zero mavity has on your body, its not so much muscle wastage that’s the problem but bone wastage. Some of NASA’s bods have suggested that the astronauts who go to mars will suffer 20-25% + bone loss during the travel there and back and will be unable to stand up on earth upon their return.

I’ve just finished an excellent book on the whole subject called packing for mars which looks at the experiments that have been done to get us where we are today and what’s being done o get us to mars. Its written in a very funny way, especially the part about the early Apollo missions and escaping poo that cause the astronauts to be lolling their heads off whilst trying to talk to Houston (all caught on tape and transcripted )

We could have got to Mars with Apollo tech if we had had the where with all to do it.

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.

Wrong as I found out in this or the other thread.

Alpha century for example is 4 light years from our perspective. Not from the lights perspective. Thus we can travel much further in space than say 70 light years in one persons life.

which is easily doable, nuclear propulsion, with an expected limit of around 8% speed of light.

I dont really understand what you wrote, however;

The technology to get there is pretty simple, The logisitics however are something completely different and whether the astronauts would be alive when they got there is another matter. It was thought at the time of the moon landing that Mars would come pretty quick but theres a reason why 40 years later we are sill not much closer than we were then

Even now there is questions about if it is possible to get the volume of provisions needed for a 2 year round trip into space in one go. The current suggestion is sending smaller crafts on a head to park up so that they can be raided on the way there. This would require follow on launches to allow them to do something similar on the way back. It wasn’t long ago that they were touting the possibility of the manned mission being one way.

Meaning if God/Jesus really was an alien, he could be back shortly and only be 10 years older. Rapture anyone ?
 
Jews and Muslims believe in this:
http://en.wikipedia.org/wiki/Tay_al-Ard
http://en.wikipedia.org/wiki/Kefitzat_Haderech

Sadly this power / technology only given to certain Humans / none Humans, only few are still alive with this power / knowledge; Humans (Mahdi, Jesus) other Humans who died long time ago (Moses, Mohammad and his family, and Virgin Mary). None Human with this technology = one or two good Demons (none_evil) died at the time of Prophet Solomon.

Once we reach this level of advancement, then Universal travel is next.

End Of line.

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.......

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?

The post you replied to was 2 years old, you dimpled yourself there.
 
mushrooms ? Gas ?

I pointed out a historical facts of powers which can make humans travel instantly to any where in the universe; I bet you didn't even clicked those links and read the quantum teleportation behind those knowledge.

Go on, put your scifi heads on and predict how many years till:-
- A human lands on the Moon again
- A human lands on Mars
- A human reaches Jupiter (Arthur C Clarke said we'd already be there :))
- A probe or human reaches another star
- A probe or human reaches another galaxy

There's a reason to go to the moon, so the next 20 years i'd imagine. Depends on how fast the Oil Crunch hits, and how fast Fusion research progresses.

I don't see much point in going to Mars at the moment, although it may be useful as a launch point for outer solar system exploration as it has water, some semblance of an atmosphere and a low mavity well.

Jupiter, well Europa is interesting and maybe Io. Again like Mars they may be useful springboards. Titan is probably the most interesting/useful of bodies in the outer solar system. There's all sorts of useful hydrocarbons there.

A probe is more likely to reach a neighbouring star first, the distances and logistics of sending people are not ideal. A probe using Nuclear Pulse Propulsion could reach Alpha Centauri in around 100 years.

Another galaxy? Until someone comes up with some new Physics not happening.

Historical Facts? Where's the evidence? :confused: Humans cannot and never have been able to travel instantly any where in the universe, and to be honest I doubt they ever will!

Keep in mind, the fastest speed any probe has travelled so far is 157,000mph. That's about 1/50th of 1% the speed of light. So to get to our closest neighbour would take approaching 20,000 years to get to!

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.
