The world’s richest man has announced plans for one of the biggest sales of stock to the public ever for a space company currently losing billions of dollars a year.

Documents filed on Wednesday show Elon Musk’s SpaceX lost 2.6 billion dollars from operations last year on 18.7 billion dollars in revenue, and the losses kept piling up at the start of this year too.
