"Space science and engineering is an interdisciplinary field covering all disciplines in sciences and engineering. The New Space era has been in development for over two decades. It is characterized by a different breed of young companies, commercialization, constellations of small satellites, reusable rockets, and orbital tourism. What used to be a government-centric industry has given way to government-private sector collaboration. The private sector is playing a major role in New Space so governments can focus their resources on missions to the Moon and other scientific explorations. Commercialization brings about wider participation and cost effectiveness."-- Provided by publisher.
