During the first half of the 20th century, science fiction novels and comic books were very popular in the United States. Their portrayal of space travel was less far-fetched than Verne's and were often based on the space reseatch of that time. For example, pictures began showing astronauts in space suits when writers realized that exposing human beings to the cold airless environment of space was lethal. ldeas of other planets were still often wrong, though. A 1928 drawing of a moon circling the planet Jupiter shows t covered in plant life. It was only discovered later that the other planets and moons around our sun are without life as we know it on Earth.
Drawings in the early 20th century also showed very large space ships and stations, almost like floating cities. Writers at the time knew that trips to other stars would take hundreds of years. Those who left Earth would die on the journey there, leaving their descendants to arrive at the destination instead. Some writers addressed this problem by using the concept of suspended animation deep sleep in which a person doesn't grow older. Such travelers would awaken at the end of their journey, hundreds of years in the future. It is not impossible that these ideas could become reality one day.
