The future of interstellar spacecraft.
The interstellar spacecraft might not come to practice very soon. But the fact is that theoretical research. Along with careful missions is opening the road to the interstellar journey. And maybe the time of that mission will come in 200-300 years. The fact is that nobody knows when we are ready to travel to the other solar system. When we remember history many things have been "impossible".
The Chinese knew how to make gunpowder rockets in the 200s(1). And the Russian Konstantin Tsiolkovsky(2)(1857-1935) created theoretical research with rocketry and spaceflight in the 19th century. The thing is that things like interplanetary spaceflights. And space elevators(3) are also invented by Konstantin Tsilkovsky.

That man is called "the Father of the spaceflight". Tsiolkovsky also created research and articles about "lighter than air aviation". There was a rumor that Tsiolkovsky created an idea to use the hydrogen balloon or high-flying airship to carry space rockets to the high altitude. And then launch that rocket to the orbiter or sub-orbiting trajectory.
The hydrogen balloon can lift the rocket to an altitude of 30 kilometers. And that thing could make it possible to launch smaller rockets to the orbiter. But for some reason, that plan remained at the theoretical level. And that reason could be bureaucracy.
The thing is that technology advances all the time. And maybe the advancing of technology is faster than we think. The thing is that the first interstellar mission might become reality sooner than we expect. The thing is that the theory is the first step for making dreams real. And modern scientists have more advanced tools and experience than Konstantin Tsiolkovsky.
But there are many things. What that man invented and what remains at the theoretical level. One of his greatest ideas is the space elevator. That giant structure that uses the centripetal force of the Earth is ever created in practice.

The British Interplanetary Society. And theoretical Project Daedalus(3) and its improvements.
There are a couple of theoretical concepts for interstellar spacecraft. All of those concepts are probes. And the carefully made steps will open the road for successful manned interstellar missions far away in the future. But the first interstellar concepts would be more primitive than some SciFi spacecraft that travels across the galaxy in a couple of weeks.
In the 1970s the British interplanetary society created Daedalus. Theoretical spacecraft. That could travel to Barnard's star. Daedalus planned to use thermonuclear detonations for reaching that distant star. In the updated version the Daedalus uses antimatter.
When Daedalus closes the objective of its mission. That craft will create antimatter by using an antimatter generator. The antimatter would be created by benefiting the solar wind which impacts the gold leaf. That thing turns those particles into antimatter. That thing makes it possible that Daedalus II could bring samples from the solar system where it visits.
NASA has created an idea of "Project Longshot" (4) which is quite similar to Daedalus. As I earlier wrote the both of those theoretical crafts are unmanned. So there are no worries about the lifetime of astronauts. But of course, there is the possibility that the theoretical interstellar probe is forgotten if there is some kind of other problems on Earth. But the time of that craft will be far away in the future.
