Why NASA Doesn't Fly Reusable Rockets?

NASA used to fly reusable rockets, but now they mostly use non-reusable ones because it's cheaper and faster in the short term.

Think of a rocket like a toy car that you ride on a track. If you have a toy car that you can pick up after each race and reuse, it’s nice, but sometimes it's easier to just throw away the old one and get a new one for the next race, especially if the new one costs less.

When a rocket lands back on Earth, it needs to be fixed. That takes time and money. It’s like when you drop your favorite cup, you might want to fix it so you can use it again, but sometimes it's faster just to get a new one.

NASA used to reuse rockets because they had more time and wanted to save money in the long run. But now, some companies build new rockets that are cheaper and quicker to make. It’s like having a factory that makes lots of toy cars fast, even if each car is only used once.

So NASA focuses on other cool things while these new companies work on making reusable rockets better!
