My father is taking on questions on astronomy & science

Humans, I believe, will evetually be able to leave solar system. They will probably start moving in the system, soon, in 10 to 20 years from now. we will be on the Moon in 2024 or the following year(s). before 2030, it is planned first humans to be on Mars. for interstellar journeys, first laser driven robotic mini (interstellar) spacecraft is being designed to start a journey to Alpha Centary system, (nearest star to us), at about 2036. It will be a mini spacecraft to be accelerated in the neighbourhood of earth to a speed of (1/5)th of the speed of light, that is 60 000 km/second and will reach the star in 20 years (in about 2056). It will include an imaging system, measurement and telecomunication devices, all built into a small (1 gram or less in weight) chip. Its data (pictures, measurements..), will reach Earth, with speed of light, in the next 5 years, in about 2061. (The star is about 42 trillion km 4.2 light years) away from the Earth.) .... IN SHORT, I BELIEVE, first ınterstellar travel for humans could definitely be realised DURING THE LIFE TIME OF next 1 or 2 GENERATIONS, BEFORE THE END OF THIS CENTURY...! YOU OR YOUR CHILDREN OR, AT MOST, YOUR GRAND CHILDREN COULD BE THE FIRST INTERSTELLAR GENERATIONS! CONGRAGULATIONS...
