Today's space flight has many additional constraints compared to 1960's space flight. For one thing, we try to avoid as much as possible hydrazine and other very toxic propellants. For another, there's a great push to reducing cost - reusability is a big part of that. Also, any component we can save weight on, we can send more mass to orbit. So we use modern design methods and materials to reduce weight. All these changes mean, pretty much, that we need a new capsule (or more radical design, e.g. Starship). |
