what is the purpose of launching and there impact on earth?
Answers
When a spacecraft is launched into orbit, it should end up spinning around the Earth quickly enough not to be pulled back in by the Earth's gravity. The huge rockets used in launching a spaceship help this to happen by giving a huge amount of thrust, enough to achieve escape velocity.
But there are many negative impacts too. Like each rocket launched into space leaves a large amount of smoke and dust in its trail. The other problems are that space is now becoming crowded. Apart from that space is now not safe with many countries like USA, RUSSIA, and CHINA having satellites that can knock each other out of the skies. But the impact on the biodiversity of the Earth is relatively low unless launch pads are situated in ecologically biodiverse.
