This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or have attempted an orbital flight attempt as of 2024; a second list includes all upcoming rockets.
A satellite in a direct orbit with an orbital period less than one day will tend to move from west to east along its ground track. This is called "apparent direct" motion. A satellite in a direct orbit with an orbital period greater than one day will tend to move from east to west along its ground track, in what is called "apparent retrograde ...
The orbit was determined by the European Space Operations Centre within 3 hours after the separation from launcher, and the satellites were operating normally and under control. [25] Both satellites were switched to safe mode, pointing at the sun while both ESA/CNES and OHB teams investigated the failure and options for the satellites.
Parking orbit for one of the early Ranger missions to the Moon. Note that the launch angle varies depending on the launch time within the launch window. In order to reach the Moon or a planet at a desired time, the spacecraft must be launched within a limited range of times known as a launch window.
It was constructed in Earth orbit and has a crew of approximately 600. [13] The whole structure is pressurised; pilots entering or exiting aircraft on the flight deck do so via airtight shafts and docking ports.

A geosynchronous orbit is an inclined orbit with an altitude of 37,000 km (23,000 mi) that completes one revolution every sidereal day tracing out a small figure-eight shape in the sky. [1] A geostationary orbit is a special case of geosynchronous orbit with no inclination, and therefore no apparent movement across the sky from a fixed ...
Alpha is designed to launch up to 1170 kg of payload to a 200 km low Earth orbit, or up to 745 kg payload to a 500 km Sun-synchronous orbit, suitable for CubeSats and other small payloads. [2] Primary payloads can be integrated by themselves or with a secondary payload , with vehicle capacity for up to 6 CubeSats.
The orbital module of the Soyuz MS includes a small forward-facing window, which allows the crew, particularly the flight engineer, to assist the commander with manual docking if automated systems fail. A hatch between the orbital and descent modules can be sealed, allowing the orbital module to serve as an airlock.
