Description

This lecture covers the historical path to Low Earth Orbit (LEO) and Geostationary Orbit (GEO), current and future missions, actors in the space industry, orbital stations, scientific missions, and the potential return to the Moon and Mars. It also explores the 'New Space' economy, including new launchers, space tourism, scientific research, and the possibility of space hotels. The lecture delves into the significance of LEO and GEO for Earth, the advancements in space technology, and the potential for the space sector to generate substantial revenue in the future.

New Space Economy

The New Space sector is a fast-growing market, boosting the historical institutional space exploration economy. The roughly 366 billion USD global space industry in 2019 is estimated to surge to over $1 trillion by 2040. The current growth in the development of space infrastructures and production of data from space is opening a full range of new applications for new customers. New business models for space encompass launchers, satellite manufacturers, in-orbit servicing, telecommunication, cybersecurity, e

Space industry

Space industry refers to economic activities related to manufacturing components that go into outer space (Earth's orbit or beyond), delivering them to those regions, and related services. Owing to the prominence of the satellite-related activities, some sources use the term satellite industry interchangeably with the term space industry. The term space business has also been used. A narrow definition encompasses only hardware providers (primarily related to launch vehicles and satellites).

Commercial use of space

Commercial use of space is the provision of goods or services of commercial value by using equipment sent into Earth orbit or outer space. This phenomenon – aka Space Economy (or New Space Economy) – is accelerating cross-sector innovation processes combining the most advanced space and digital technologies to develop a broad portfolio of space-based services.

Space debris

Space debris (also known as space junk, space pollution, space waste, space trash, space garbage, or cosmic debris) are defunct human-made objects in space - principally in Earth orbit - which no longer serve a useful function. These include derelict spacecraft - nonfunctional spacecraft and abandoned launch vehicle stages - mission-related debris, and particularly numerous in Earth orbit, fragmentation debris from the breakup of derelict rocket bodies and spacecraft.

Orbital maneuver

In spaceflight, an orbital maneuver (otherwise known as a burn) is the use of propulsion systems to change the orbit of a spacecraft. For spacecraft far from Earth (for example those in orbits around the Sun) an orbital maneuver is called a deep-space maneuver (DSM). The rest of the flight, especially in a transfer orbit, is called coasting.

Orbital spaceflight

An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To do this around the Earth, it must be on a free trajectory which has an altitude at perigee (altitude at closest approach) around ; this is the boundary of space as defined by NASA, the US Air Force and the FAA. To remain in orbit at this altitude requires an orbital speed of ~7.8 km/s. Orbital speed is slower for higher orbits, but attaining them requires greater delta-v.
