Non-ballistic atmospheric entry

When rockets or other spacecrafts travel to space, they have to enter the Earth's atmosphere again to come back home. But, how do they safely come back to Earth without crashing?

Non-ballistic atmospheric entry is a way for spacecraft to re-enter Earth's atmosphere without using a direct and steep path. Instead, they use a slower and more controlled angle, like a plane coming in for a landing. This allows for a smoother and safer landing.

Think of it like jumping from a high diving board into a swimming pool. If you jump straight down, you'll hit the water hard and it won't feel very good. But if you jump in at an angle, you'll glide into the water more smoothly.

The spacecraft uses things called heat shields and parachutes to help slow it down even more, which also helps keep everything and everyone inside safe. The heat shields are made of strong materials that can withstand the extreme heat caused by the friction of the atmosphere. The parachutes slow the spacecraft down even more and allow for a gentler landing. It's kind of like using a big fluffy cushion to land on, instead of hitting the ground hard.

Overall, non-ballistic atmospheric entry is a safer and more controlled way for spacecrafts to come back to Earth and keep everyone safe.
