The Reality of SpaceX's Impact on the Commercial Space Race.

Ashlee Vance's new book, "When the Heavens Went on Sale," profiles four companies in the commercial space race: Planet Labs, Rocket Lab, Astra, and Firefly Aerospace. Vance believes that SpaceX and Rocket Lab are currently the dominant players in the industry, but there may be room for competition if Rocket Lab can build a bigger rocket before SpaceX's Starship launch system is completed. Vance also discusses the potential for a retrenching in the industry and the question of how many rockets will be needed to meet the demand for launching satellites.
