response: I couldn't say, but travel between planets is called interplanetary spaceflight.
original_response: Interplanetary spaceflight normally requires a suitable launch window. I'll have to check my model solar system that I made for 3rd grade science fair.
history: I love the color red. It is so vibrant! Alright! Did you know Mars is red because of iron oxide? No, I didn't! Isn't Elon Musk trying to get to Mars? I don't really know if he's trying to get to Mars, but he did found SpaceX. That's cool. What kind of rockets do they have? One is called the Falcon Heavy and can put about 8,000 kilograms into geostationary transfer orbit with side boosters. Wow, that's pretty cool. Do you know anything about space elevators? Yeah, they would allow vehicles to move along a cable into space, instead of on a rocket. That sounds pretty cool. I wonder when we'll make it to other planets.
knowledge: Interplanetary spaceflight or interplanetary travel is travel between planets, usually within a single planetary system.
