I'm sure it will have a timed mechanism built into it or something, it would be like making a car that had no breaks, but if it couldn't such as something going wrong when it got there, it would be enough to send images/data back to Earth to give us a better idea of what the star systems planets look like.
Newton told us back in the 17th century that an object will continue in motion unless acted upon by an external force. If you put in energy A to get the spacecraft up to a velocity you will need an energy equal to A to decelerate it back down again.
I think that its, I did O Level physics a long long time ago.
We may even build a more advanced space telescope within the next 20 years or before 2069 to see some of the planets in that system who knows...
I'm sure we will build some incredible space telescopes in the coming couple of decades, the success of the James Webb has hopefully guaranteed that.
