Scientific research in the field of spaceships: are interplanetary travels possible?
In early days people might never think about going to moon or any other planets. But when technology is more advanced scientists try to explore many things in spaceship. There is competition among rich countries in this field. They spend a lot for just a mission and for such travel they chose suitable person who is physically and mentally fit for such trip. Also that certain person should be very good in technical knowledge, so he or she can try to solve problems facing on trip.
According to science research interplanetary travels are possible. There's no law of physics that outright forbids it. But that doesn't necessarily make it easy, and it certainly doesn't mean we'll achieve it in our lifetimes, let alone this century. Interstellar space travel is a real pain in the neck.
Interplanetary travels happening takes some time. It might not happen in this century too. For such challenging one scientist need more research work and study work. It takes time to go spaceship also time. Travelling is also a big challenging for such mission. Also the mode of transport should be design for this. Also if we are able to design a spaceship that can travel how much quick means still it takes a lot of time. According to scientists crossing our own galaxy takes more than 1 million years and a trip to the nearest galaxy will take more than 2 million years.
