Would it really require very much more fuel? Once you're headed in the right direction, you can just coast. Who cares if it takes months for the payload to get

Would it really require very much more fuel? Once you're headed in the right direction, you can just coast. Who cares if it takes months for the payload to get there?

No this is not how orbital mechanics work. You need to escape the earth's gravity completely to go to the sun. In order to go tot the moon you don't. The "Just point at it and keep going" doesn't work in an orbital system. Here's a nice delta-V map that explains it a bit more: https://www.reddit.com/r/space/comments/1ktjfi/deltav_map_of_the_solar_system/ https://www.reddit.com/r/space/comments/1ktjfi/deltav_map_of...
