Besides moon or Mars exploration, why not explore the milky way?
Why only solar system? There is lot more than solar system in milky way

we need speed holmes,a lot more of it,,half the speed of light would be a good start,,we are turtles on the shore of the pacific on a 100 meter round island,,wondering ]hownihell to we get out there sonny?'

Short answer, the traveling time to:
- the Moon: 3 days
- Mars: 6 months
- closest star system (Alpha Centauri): 70,000 years (at Voyager speed)
- Milky Way crossing: 1.7 billion years
Unless we master wormhole, warp factors, or hyperspace travel, it will be the Solar System only.

The Milky Way is farther than u can imagine litteraly

Because the fastest spacecraft we have now, which are just small space probes, would take about 40,000 years to reach the closest star outside our solar system, if it was headed that way. Humans do not yet have a spacecraft that has the capability to make interstellar travel practical.

We will get there eventually

The issue is distance... The objects in our solar system take months and years to reach with our current technology... an example are the two Voyager probes. They've been in space for 42 years - and have only reached the Kuiper Belt in the last few years. They'll spend thousands of years going through the Kuiper Belt, then the Oort cloud, before finally leaving the influence of our sun...
And the nearest star is Proxima Centuri - at their current speed, Voyager will take about 18,000 years just getting that far. And the Milky Way stretches for thousands of light years beyond that.

We are, but consider the two probes launched back in 1977 are only just now leaving our solar system. The nearest star to ours is just under 2 light
years away. (Oops, planetoid, not star)Nearest system is 4 Ly. Not even out of Orion arm yet.
Milkey Way is not small. Even if light speed were possible, still take centuries to tool the galaxy.
I do that with Celestial, takes 2 seconds to visit Andromeda (M31).

Hey good idea. Let's go to the nearest stellar system which is Proxima Centauri. It's only 4.2 light years away. Given that we might be able to reach, say, 1/4 light speed with our technology in the next 20 years, it would take roughly 20 years one-way to get to that star. Give the crew a year to explore the planets around Proxima Centauri, then another 20 years back to Earth.
That's forty plus years round trip...to the nearest star in the galaxy. The next nearest is over ten light years away. So we can chalk up over 80 years round trip for that one.
Are you getting the picture? The Milky Way is a very big place, stretching 100,000 light years in diameter. That's why we have no plans to explore the Milky Way. It's way too big and we're way to slow to do that in the expected life-time of our planet.

Explore as in travel? Too expensive. Do you think NASA has never thought of that?

Someone should colonise Uranus.
