Not counting on it happening in my lifetime, granted how crazy the world has been for the last 15 years and what is seemingly to come. I know that the propulsion schematics and technology we used to disembark the moon were lost though, and this supposedly occured before databases, intranets, and significant data storage options were available. It was simple to lose knowledge about such complex things back then.

The bush administration dropped project CONSTELLATION with the intention of getting people back up there, but none of the higher ups really looked into the why. Unsurprisingly, the government now wants to schedule a mission to Mars, without having solved the propulsion system issue.

I could go on about that issue for some time, but for now I think our best goal, at least for now, is to develop new ways of moving large amounts of data over long distances, without having to physically move it. We still use radio waves to transfer data from the equipment we've sent to Mars, which severely limits the volume of data we can get back and analyze. That technology is more than a century old now.We primarily use optical fiber to transfer data over long distances here (the internet), but it's fairly crude in the medium of inter-system data transfer.

Needless to say, we have A LOT of domestic things to figure out before we make a milestone of moving people next door.
