That’s debatable. We’ve learned how to spend a lot of time in space. We’ve found that sugar will coagulate itself thus giving us some insight into how rocks and dust in space might cohere to start the nucleus of a planet’s development. We’ve discovered that bone density decreases drastically in micro gravity. We’ve had some great photos. We found out you can play a guitar in micro-gravity. We’ve spent a whole lot of money, and continue to spend $5 billion a year just to maintain it. We plan to take it apart if nobody wants to buy our share and de-orbit over the ocean. Was it all necessary? The space shuttles were the most disastrous space program ever. More people died than ever before, burning up on launch and burning up on reentry. Now we hitch rides with Russians. It’s very pretty to see it go overhead – a big bright white dot racing across the night sky. Did I mention it’s debatable?
- If aliens exist, how intelligent and powerful do they have to be to reach Earth?
- How far has our first radio broadcast spread into space?
- Have astronauts really been to outer space or are they simply faking it?
- How do I communicate with extraterrestrial life from another solar system with laser beams to send them a message?
- Why did the Russians use their probe immediately on Venus, but NASA waits days to use ingenuity on Mars?
