the transport vehicles—including size, construction material, number and type of engines, thrust, cargo and passenger payload capabilities, on-orbit propellant-tanker refills, representative transit times, etc.—as well as a few details of portions of the Mars-side and Earth-side infrastructure that SpaceX intends to build to support the flight vehicles. In addition, Musk championed a larger systemic vision, a vision for a bottom-up emergent order of other interested parties—whether companies, individuals, or governments—to utilize the new and radically lower-cost transport infrastructure to build up a sustainable human civilization on Mars, potentially, on numerous other locations around the Solar System, by innovating and meeting the demand that such a growing venture would occasion. In July 2017, SpaceX made public plans for ITS based on a smaller launch vehicle and spacecraft. The new system architecture has "evolved quite a bit" since the November 2016 articulation of the very large "Interplanetary Transport System". A key driver of the new architecture is to make the new system useful for substantial Earth-orbit and cislunar launches so that the new system might pay for itself, in part, through economic spaceflight activities in the near-Earth space zone. The Super Heavy is designed to fulfill the Mars transportation goals while also launching satellites, servicing the ISS, flying humans and cargo to the Moon, and enabling ballistic transport of passengers on Earth as a substitute to long-haul airline flights. Since March 2020, SpaceX conducted several test flights of their Starship spacecraft. The Starship is a fully reusable two-stage vehicle designed to take passengers and cargo to the Moon, Mars, and beyond. SpaceX had initially planned to have an orbital-flight in 2021. On Wednesday, May 5, 2021, the twelfth Starship prototype (SN15) made a 10 km suborbital flight and achieved soft landing. SpaceX is currently in the process of improving and understanding the Starship spacecraft. NewSpace terminology The term "NewSpace" emphasizes the relative modernity of private spaceflight efforts, encompassing international and multinational efforts to privatize spaceflight as a commercial industry. Such corporations fall under the governance of international treaties and national governments. See also List of commercial space stations References Belfiore, Michael.
