Here you'll find detailed descriptions of the activities of the Mobility and Robotic Systems Section, as well as related robotics efforts around the Jet Propulsion Laboratory. We are approximately 100 engineers working on all aspects of robotics for space exploration and related terrestrial applications. We write autonomy software that drives rovers on Mars, and operations software to monitor and control them from Earth. We do the same for their instrument-placement and sampling arms, and are developing new systems with many limbs for walking and climbing. To achieve mobility off the surface, we are creating prototypes of airships to fly through the atmospheres of Titan and Venus, and drills and probes to go underground on Mars and Europa. To enable all of these robots to interact with their surroundings, we make them see with cameras and measure their environments with other sensors. Based on these measurements, the robots control themselves with algorithms also developed by our research teams. We capture the control-and-sensor-processing software in unifying frameworks, which enable reuse and transfer among our projects. In the course of developing this technology, we build real end-to-end systems as well as high-fidelity simulations of how the robots will work on worlds we are planning to visit.

Home Products About Us Applications ... News Peroxide Propulsion Stuart Ross Rocketbelt Peroxide Propulsion, Gothenburg, Sweden, is a producer of Rocket Grade Hydrogen Peroxide , also called HTP (High Test Peroxide). Start of production was in May, 2006. Lower grade hydrogen peroxide is concentrated to 80-90% concentration in the plant and treated in special processes to receive very pure products well suited for gas generation and rocket propulsion. Read about the products that in addition to hydrogen peroxide includes decomposition catalysts. Background Monopropellant hydrogen peroxide rockets are mechanically simple and have a low weight while still being powerful. On the following pages we will describe how these rockets work and about our own work in the field. You will get some guidelines on how to design a rocket system and you can buy the catalyst needed to decompose the hydrogen peroxide to hot steam and oxygen. The rockets are best suited when you need a low weight engine to develop a high power during shorter periods of time because they have a high fuel consumption. A light weight autogyro (gyroplane) needs 1 liter of hydrogen peroxide during 15 seconds, to take off vertically with hydrogen peroxide rockets at the rotor tips. After take-off, the autogyro is powered with a propeller and a conventional combustion engine (or towed after a car if it is a glider). Drag racing and personal rocket belts are other examples where hydrogen peroxide rockets are used. You will find more fascinating uses on the following pages - both historically, like during WWII, and today.

W elcome to the Plasmadynamics and Electric Propulsion Laboratory (PEPL) at the University of Michigan Department of Aerospace Engineering . The lab was founded in 1992 under the direction of Professor Alec Gallimore and since that time has been embarked on an experimental and theoretical program with the following goals: To make electric propulsion (EP) devices more efficient and of better performance; To understand spacecraft integration issues that could impede the widespread use of these devices on scientific, commercial, and military spacecraft; and To identify non-propulsion applications of EP systems (e.g., plasma processing, space-plasma simulation). The centerpiece of the laboratory is the large vacuum test facility that was built in the early 1960s by the Bendix corporation and was later donated to the university in 1982. This cylindrical stainless-steel clad tank, which is 9 m long and 6 m in diameter, is the largest vacuum facility of its kind at any university in the nation. At high-vacuum, the chamber employs seven cryopumps, with a combined pumping speed of 500,000 l/s on air, and 240,000 l/s on xenon.

Flying on Fusion Power Lots More Information See all ... articles Humans have landed on the moon several times, and flying into Earth orbit today seems routine. Space is even a long-term settlement to some astronauts onboard the International Space Station . However, when you think of the size of our solar system, not to mention the universe, we have just taken baby steps into space. In order to go to Mars and other planets that are out of the reach of conventional rocket engines NASA is developing several advanced propulsion systems, including one that harnesses the power of the sun Photo courtesy NASA Artist's concept of a fusion-powered space vehicle approaching the Saturn moon Titan Basically, fusion-powered spacecraft are designed to recreate the same types of high-temperature reactions that occur in the core of the sun. The enormous energy created from those reactions is expelled from the engine to provide thrust. Using this type of propulsion system, a spacecraft could speed to Mars in just about three months. It would take conventional rockets at least seven months to reach Mars.

But the struggle to unlock the secrets of our solar system presents unique new challenges. Central among them: faster access throughout the solar system, and the ability to rendezvous with, orbit and conduct in situ exploration of planets, satellites and other solar system bodies. This is the objective of NASA’s In-Space Propulsion Technology Program: to develop in-space propulsion technologies that can enable or benefit science at new destinations; to significantly reduce the time, cost and mass required for spacecraft to reach their destinations - in other words, to "Get More Science Sooner". Accomplishment of this objective will allow mission planners to shift their focus from the difficulty of the journey to the science challenges at the destination.

40. Space Plasma Physics Modelling Page An advanced plasma propulsion system that will create a large scale magnetic bubble around the spacecraft to ride the solar winds. http://www.ess.washington.edu/Space/propulsion.html

Advanced Electric Propulsion Chemical rockets have limited application for space applications due to the fact that the fuel is relatively slow (low specific impulse) relative to the speeds needed to move efficiently about the solar system. As a results chemcial systems are massive, and the trip times for missions are very long. Research at UW in this area is for the development of faster propellants that can provide substantial reductions in cost and trip time. To achieve these efficiencies plasma systems (i.e. charged particles) are required where electric and magnetic field can be used to accelerate the plasma propellants to speeds more than an order of magnitude faster than can be achieved by chemical rockets. The systems below detail devices under active development. Cast of Characters: Robert M. Winglee Areas of Active Interest: High Power Helicon is an electrodeless plasma thruster that is able run at kW to 100's kW to produce thruster levels as high as several Newtons of force, at high power and gas effciency. Mini-Magnetospheric Plasma Propulsion (M2P2) is a system that can leverage energy from the solar wind to augument the onboard propulsion for spacecraft while minimizing the spacecraft power requires. Potential for radiation shielding is still under investigation.
