Some spacecraft propulsion methods such as solar sails provide very low but inexhaustible thrust; [31] an interplanetary vehicle using one of these methods would follow a rather different trajectory, either constantly thrusting against its direction of motion in order to decrease its distance from the Sun, or constantly thrusting along its ...
The National Institute of Aeronautics and Space (Indonesian: Lembaga Penerbangan dan Antariksa Nasional, LAPAN) was the Indonesian government's space agency. It was established on 27 November 1963, by former Indonesian president Sukarno, after one year's existence of a previous, informal space agency organization. LAPAN is responsible for long ...
Space technology is technology for use in outer space. Space technology includes space vehicles such as spacecraft , satellites , space stations and orbital launch vehicles ; deep-space communication ; in-space propulsion ; and a wide variety of other technologies including support infrastructure equipment, and procedures .
In the last case Dawn provided them with its own proprietary propulsion architecture. [9] [10] [11] Dawn Aerospace has also signed contracts with Indonesia's national space agency, working to provide the propellant for a new satellite network dedicated to providing early warning of tsunami and earthquake related phenomena.

The first test of electric propulsion was an experimental ion engine carried on board the Soviet Zond 1 spacecraft in April 1964, [16] however they operated erratically possibly due to problems with the probe. [17] The Zond 2 spacecraft also carried six Pulsed Plasma Thrusters (PPT) that served as actuators of the attitude control system. The ...
A pulsed plasma thruster (PPT), also known as a Pulsed Plasma Rocket (PPR), or as a plasma jet engine (PJE), is a form of electric spacecraft propulsion. [1] PPTs are generally considered the simplest form of electric spacecraft propulsion and were the first form of electric propulsion to be flown in space, having flown on two Soviet probes (Zond 2 and Zond 3) starting in 1964.

The Swift spacecraft is an example of a spacecraft that does not have a propulsion subsystem. Typically though, LEO spacecraft include a propulsion subsystem for altitude adjustments (drag make-up maneuvers) and inclination adjustment maneuvers. A propulsion system is also needed for spacecraft that perform momentum management maneuvers.
