Here is a concise explanation of how solar sails work. Although the idea seems simple, the mass of the spacecraft that would be used would undergo trial and error. If that's done, then using the sun's rays would be convenient.

Maybe that skill is still being taught to seamen because it remains that anything can happen when you're in the waters. If you plan on travelling to rainforests, knowing how to use stars will also be useful. It's always good to have extra skills for the sake of self-sufficiency and emergency.

I'd love to experience seeing the moon while riding a boat in the ocean, where it appears close, given its majestic size. I think only specific countries on Earth would allow that view, though.

An alien invasion may unite the world because it's a fact that different countries have their strengths and weaknesses. It's just a situation that who knows how long we can endure if these aliens would be aggressive.

While innovative, this project might bring psychological problems to astronauts who will be staying in that space station. It was mentioned that the architecture would be claustrophobic, even being shared with others. I can't imagine being in there for a long time, so I can only hope for willing astronauts to have good health. Since every component has to be calculated, there's no choice but to sacrifice comfort.

I bet Venus would be the most challenging planet to study or even explore, with temperatures rising to levels that can even melt lead. Even though Venus is also nearer to Earth compared to most planets, the type of environment it has equates to a suicide mission.

That's like having a free heater or a natural Asian bathhouse! I'd still love to visit a waterfall, even if everything is purely cold. Besides, I've heard that cold water can help increase stress tolerance.

Travelling to outer space may become an emergency option instead of a luxury if resources for that ride will be continuously consumed. It's appalling that even though we're already lacking resources, some would still consider space ride for fun.

I think it helps if different nations have their space stations, given the possibility that it may quicken technological advancements in space. The new satellite released from the Tianzhou cargo ships is expected to assist astronauts in their missions by helping with instructions and delivering supplies. Hopefully, though, this equipment will only be used for science.

Quote from Patricia

Every couple of million years there's a probability that earth may be hit by an extinction threatening asteroid like it happened to the dinosaurs. It's only wise that we be prepared since it's not a matter of if, but rather when such an asteroid will be headed for earth again.

That's true. The dangers and destruction that asteroids will bring in the near future are inevitable, and learning our way around them and developing safety measures is the only thing we can do.

These kinds of videos are indeed creepy, but seeing the behind-the-scenes make them less scary. What I'm more worried about is getting surprised by the sounds since videomakers always rely on that factor.
