Future spacecraft propulsion

Journal of Propulsion and Power, 1988
Propulsion requirements for launch vehicles, upper stages, satellites and platforms, and planetary spacecraft are described from a functional perspective and compared on an energy basis. Mission velocity requirements for a range of missions are presented.

Spacecraft Propulsion: New Methods

Science, 1972
Cosmic plasmas contain energy which may be tapped and used for spacecraft propulsion. The energy needed for launching a spacecraft could be supplied to it from the ground through a plasma channel in the atmosphere.

CNES Propulsion Activities for Spacecraft

41st AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2005
This paper presents an overview of the CNES spacecraft propulsion activities. The main existing and future projects corresponding to low earth orbit and geostationary platforms are described. These projects cover various types of propulsion subsystems: monopropellant, bipropellant and electric.

Spacecraft propulsion systems

Physics in Technology, 1984
The failure of a number of communications satellites to reach orbit in 1984 brought the space industry back into the public eye in an undesirable manner. The author investigates the propulsion systems which usually deliver their spacecraft to the desired orbital position but sometimes ...

Lightweight spacecraft propulsion system selection

23rd Joint Propulsion Conference, 1987
Various methods of significantly reducing the mass of planetary spacecraft propulsion systems were addressed. Because of the Space Shuttle Challenger accident, the availability of the Space Transportation System for planetary missions may be limited.

Advanced Propulsion for Future Planetary Spacecraft

Journal of Spacecraft and Rockets, 1981
Advanced propulsion concepts are evaluated for unmanned exploration class missions to the outer planets. Spacecraft propulsion requirements for these missions are compared with those for previous missions. A major improvement in performance above that offered by current systems is needed to deliver the payloads required by these missions in an ...

Fuel optimal propulsive reboost of flexible spacecraft

Dynamics Specialists Conference, 1992
This paper presents for the first time an exact solution to the fuel optimal propulsive reboost problem for flexible spacecraft. The spacecraft undergoes rigid-body motion and flexible-body motion and reboost is achieved propulsively through the use of reaction control jets.

Interplanetary Spacecraft Design using Solar Electric Propulsion

Journal of Spacecraft and Rockets, 1974
Emphasis of the electric propulsion technology program is now on the application of solar electric propulsion to scientific missions. Candidate planetary, cometary, and geosynchronous missions are being studied. The object of this paper is to describe a basic spacecraft design proposed as the means to accomplish (1) a comet Encke slow flyby, (2) a ...
