A new Space era is already ongoing. The commercial use of Space for telecom, Earth observation and navigation, and its vast number of applications have created a backbone for economic and societal prosperity for mankind on Earth. These are all built on the fundaments laid down by that very first launch and its further evolution that led to the #PlutoFlyBy.
Untill July 16, 2015, the true commercial use of Space for exploration was never part of the new Space era. That day, the US based private company Planetary Resources deployed its first prototype in Space of a machine, that one day will lead to economic value created in Space, by finding valuable resources on near-Earth asteroids. The A3R spacecraft tested critical technologies and functionalities to obtain technology building blocks for future deep space asteroid prospecting spacecraft. The new Space era has now really started with its own Sputnik: the A3R. (Note: because the business case for asteroid mining is so far away, Planetary Resources could not keep open shop by itself and was acquired by Consensys in 2018).
