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 80 kilometers (50 mi); this is the boundary of ...
Space Centre Australia secured land for main site facilities for space launch, located 43km east of Weipa, close to RAAF Scherger in 2023. [91] Final approvals may come under Mokwiri Aboriginal Corporation. [91] Previously a Cape York Space Agency was established by the government to develop a facility for Ukrainian Zenit launches at
Spaceflight in 2025 promises to follow the 2020s trend of record-breaking orbital launches (with at least 300 expected) and increased developments in lunar, Mars, and low-earth orbit exploration. Overview
For the list of predominantly solid-fueled orbital launch systems, see: Comparison of solid-fueled orbital launch systems. Spacecraft propulsion [note 1] is any method used to accelerate spacecraft and artificial satellites. Orbital launch systems are rockets and other systems capable of placing payloads into or beyond Earth orbit.
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth , but also includes space probes for flights beyond Earth orbit.

The Spacefacts list includes most flights listed here, but omits twelve: The three failed launches of STS-51-L, Soyuz T-10a and Soyuz MS-10, none of which achieved human spaceflight, the uncrewed launch of Soyuz 34 (which nevertheless returned a crew to Earth), and the eight sub-orbital human spaceflights: Mercury-Redstone 3 and 4, X-15 flights ...
The two astronauts completed the longest spacewalk in human history with the assistance of the space station's robotic arms and ground-based scientific personnel, completed tasks such as the installation of space debris protection devices, inspection, and maintenance of external equipment and facilities.
