Graduate student Lauren Weiss is working with Berkeley SETI Research Center's Prof. Geoff Marcy, searching for Earth twins and exploring where life might be found in the Universe. Find out more in our latest video profile: https://youtu.be/7KG50exx_rg

Will we ever be able to send satellites to other systems? If yes, can we get an educated guess on when it would be possible?

The nearest star system is 4 light-years away. Assuming we could send matter at light-speed, we couldn't expect a signal back for 8+ years. In practice you need to accelerate to speed, then decelerate to match velocity at destination. We need hyperdrive/wormholes/whatever before it's ever going to be feasible, normal propulsion systems won't cut it.

Well, when Doctors are implanting pacemakers and telling the patient, the battery will need to be replaced in 10,000 years, here is your appointment card, then you can ask that question and get a good educated guess. In other words a very long time in the future.

We could probably do it now however as Ivan implied no one alive today or in the next few generations would be alive when it arrived there and as far as I know the current technology does not exist for it to send back a data.

Well, we have sent Voyager 1 & 2, Pioneer 10 & 11, New Horizons, but none of them will be operating when they get in the vicinity of a star. We have no ability today to construct a probe that can remain operational for tens of thousands of years. No fuel source. No belief that we can build a computer to run that long. No mechanical parts to orient a spacecraft. No radio transmitter. So if the question is can we fling something off planet to a star, the answer is yes. Sending something that will operate when it gets there, no way.
