I asked a friend who is fascinated by astronomy, and he is an amateur in space and satellites.
Q: What do you think about the concept of satellite?
A: A satellite is something that orbits, or goes around, a planet or a star, and there are lots of different types. Some natural things are satellites – like the Moon, because it goes around the Earth, but usually, when people talk about satellites they mean the ones that were made by people. They’re sort of like spaceships moving around the Earth, and they’re usually made up of a computer, along with solar panels to get power from the Sun. Sometimes they also have cameras or other scientific tools to help gather information.
Q: What is the situation in space right now?
A: Junkyard…We’ve launched rockets and spacecraft into Earth’s orbit, but now thousands of objects from tiny screws and bolts, to dead satellites encircle the Earth. Transforming the space above us into a junkyard.
Q: What is space junk?
A: any man-made object in orbit around the Earth that no longer serves a useful function
Q: What is the damage of space junk?
A: It directly threatens people in space like ISS(International Space Station), which is in the crosshairs. ISS has already been hit by little bits of debris on a number of occasions and there are no guarantees that other substantial things might not hit it again in the future.
Q: What do you think about the future space environment?
A: Getting worse I guess? You know SpaceX plan to launch 12,000 satellites in space, but we already have 6,000 satellites in space right now and it has already been a junkyard, I think it will become more severe in the future.
According to the interview, I’ve learned lots of space environment problems and also concerned about our future. It’s a good direction to develop my satellite guide.
