Why does liftoff occur when a spacecraft lands?
Liftoff does not occur when a spacecraft lands; rather, it is a term used to describe the launch of a spacecraft into space. When a spacecraft lands, it typically descends from orbit or atmospheric flight to touch down safely on a surface. The operation of landing involves slowing down and controlling descent, which is the opposite of liftoff, where the spacecraft accelerates to overcome Earth's gravitational pull. Therefore, liftoff and landing are distinct phases of a spacecraft's mission.
Can you use parachutes in space?
No, parachutes require air to create drag and slow down descent. In outer space, there is no air to provide resistance, so parachutes would not be effective. Other methods, like retro rockets or aerobraking, are used for spacecraft to slow down.

Why can astronauts not use parachutes to heip slowdown their spacecraftsas it approaches the moon how do they slowdown their spacecraft?
Astronauts cannot use parachutes to slow down their spacecraft when approaching the Moon because there is no atmosphere on the Moon to deploy parachutes effectively. Instead, spacecraft use propulsion systems like engines or thrusters to slow down as they approach the Moon. By firing these engines in the opposite direction they are traveling, they can reduce their speed and enter lunar orbit safely.

What is the term for slowing down in skiing?
snowploughing is the term used when you slow down by making a wedge shape with your skis, it is mostly taught for when you are just learning how to ski, but it is not a good stop for the backcountry. Once you get more advanced you can do stops such as the hockey stop, and slow down using movements with your skis that are sometimes called speed checks, these two other stops are much better, but take more practice to learn
