TECHNICAL DEFINITION

A capsule is a self-contained, often blunt-bodied spacecraft module designed for crew or cargo transport, typically featuring a heat shield for atmospheric re-entry and a parachute system for landing, forming the primary habitable volume for short-duration human spaceflight missions.

BACKGROUND

The billionaire space race is the rivalry among entrepreneurs who have entered the space industry from other industries – particularly computing. This private spaceflight race involves sending privately developed rockets and vehicles to various destinations in space, often in response to government programs or to develop the space tourism sector. Some of this competitiveness is part of the New Space Race.
