Elon Musk said SpaceX will use

After all, SpaceX wants to recover every part of the missile after launch, not just the first floor, and the company might have to use tactics to better control the missile's layers. .

Elon Musk has stated that the company will find the upper layers of the missile out of orbital velocity by using a "giant balloon".

"This may sound crazy, but . S paceX will try to bring the upper floors of the missile from still orbit with a giant balloon."

Yes, he himself knew that this sounded "crazy". He has yet to reveal more information about this issue.

If such a system can work, it will bring many benefits to SpaceX. Until 2018, SpaceX estimated costing up to 62 million USD for a launch, with the first floor landing successfully. If the company can slow down and recover the missile's upper layers by relatively low-cost methods such as using balloons, SpaceX can both reduce costs, and make rocket launchers more More attractive for customers.

No matter how crazy this idea is, the idea is not to burn the bag, but to be environmentally friendly (dead rockets will not hit the Earth). Perhaps using balloons is not a bad idea either.
