[The Matrix] How far out into the universe does the Matrix try to imitate?

I don't remember much from the sequels, but is it ever touched upon just how much of our universe is actually explorable by humans plugged inside the matrix? Are there astronauts? Are they sending space probes to explore other parts of the Solar System? Could someone plugged into the Matrix fly a manned craft to the Moon, land and collect samples to take back to Earth? I guess I'm wondering if the machines felt the need to incorporate much outside of our planet in terms of spaces humans could physically interact with. Like the Truman show has a limit where he can explore until he eventually hits the wall of the giant studio. Would the same happen in the Matrix?

*edit* Thanks for the comprehensive answers!

Probably just shy of the exosphere. Namely because Assuming space exploration in 1999 is relevant. Also HOW much of the world is prevelant in the matrix when only ONE city is ever mentioned.

A large number of facsimiles of other parts of Earth also apparently exist within the Matrix even though most of the Matrix trilogy is set within the Mega City.    The computer screen in Neo's apartment during his first appearance shows his research. One of the news articles places Morpheus at Heathrow Airport which is in the United Kingdom.    The protagonist of the short story Goliath visits many other locations in the United Kingdom, including Edgware, North London, Tottenham Court Road, the Northern Line, the Euston railway station, and a house near Dartmoor, all of which are implied to exist within the Matrix (or a future version of it). The protagonist also mentions foreign powers such as the USSR and the Iranians.    Another such story was from a website of Al-Nahar.    In the webcomic Déjà Vu, a stockbroker's wife who has the ability to see into the future of the Matrix warns the public that a major earthquake will strike San Francisco. When the earthquake happens, hundreds of lives are saved because of her prediction.    The ending of The Animatrix short film World Record has a crippled Dan Davis in a wheelchair pushed by a chatty bluepill nurse talking about her aunt "living in a villa in France".    The Animatrix short film Beyond is set in a part of the Matrix that resembles a contemporary, urban Japanese metropolis highly akin to or quite possibly being Tokyo or Kyoto.
