Would you accept a mission to colonise another planet if it means never returning back to earth ?
After the film Passenger(film synopsis = While 5,000 long-sleeping passengers travel through space to a new planet, two of them are accidentally pulled out of their artificial sleep 90 years too early. Jim and Aurora must now accept the idea of spending the rest of their lives on board the spacecraft. As they gradually feel an undeniable attraction, they discover that the ship is in grave danger. The lives of the thousands of sleeping passengers are in their hands...), we can ask ourselves if travel in space is possible for human beings even though it means leaving the earth forever ? Will the curiosity or the overpopulation of the planet decide us ? Only future will tell us the answer ! Do you have a opinion ?

In the 19th century in the United States, poor people wanted to conquer the western territories in order to survive. Today, if the land is no longer liveable because of pollution, young people will try to colonise à planet, I am sure of that. For the people of my generation it's much too late.

However, attention will have to be paid to health problems
https://pubmed.ncbi.nlm.nih.gov/3490786/
Several consistent medical problems have been encountered by astronauts during space flights. These include vestibular dysfunction, weight loss, increase in height, upward fluid shift, anemia, cardiovascular deconditioning, muscle atrophy, and bone loss. Almost all of these alterations can be attributed to the absence of gravitational force. Most are adaptive in nature and therefore reversible, but readaptation after returning to earth may cause further problems (e.g., in the case of vestibular dysfunction). The most recalcitrant and disturbing of all these problems is the relentless bone loss associated with negative calcium balance. This problem appears to be irreversible, and critical demineralization can occur after two years in a weightless state. Unless its mechanism is elucidated and preventive measures are taken, the bone loss may prove to be the medically limiting factor for the duration of space flight.
