Some sort of cryogenic hibernation for space travel is not unrealistic within the next few decades. https://www.airspacemag.com/space/hibernation-for-space-voy

  Even with that I hope we get to see missions where they send unmanned craft in that direction in my lifetime. I mean it's still only Voyager and New Horizons (afaik) that have been sent on a trajectory out of our own solar system on purpose. (faux edit: looking up the wiki page, it's the 5th to escape the solar system). An unmanned mission would probably have to go even faster, and probably has to be a bigger craft with better on-board power supply (with backups) and a big communications array. Maybe it would even need similar craft following it after a while to form a chain of communications relays on their way out.

    Nitpick: 5th to reach solar escape velocity. New Horizons, Pioneer 10, and Pioneer 11 have not passed the heliopause yet, which is usually considered the "boundary" of the solar system.

    >in my lifetime Well, that's easy to say for you, given your nickname. ;-)

  It is extremely unrealistic within the next few decades.

  Right now, there is zero requirement, or desire, to send humans into deep space. Whats more likely to happen, is ~500 years of unmanned space exploration before we even think about sending people out there.
