“…Two distinct independent micro propulsion systems were hosted on board the LPF S/C: coldgas micro propulsion thrusters, as inherited from the Gaia mission (Scharlemann et al, 2011), and 8 CMNTs developed by Busek and managed by NASA at the Jet Propulsion Laboratory (Ziemer et al, 2006) which were part of the DRS. The DRS included four subsystems: the Integrated Avionics Unit (IAU), two clusters of four CMNTs each, the Dynamic Control Software (DCS) and the Flight Software (FSW).…”

The Laser Interferometer Space Antenna (LISA) of the European Space Agency (ESA) will be the first low-frequency gravitational-wave observatory orbiting the Sun at 1 AU. The LISA Pathfinder (LPF) mission, aiming at testing of the instruments to be located on board the LISA spacecraft (S/C), hosted, among the others, fluxgate magnetometers and a particle detector as parts of a diagnostics subsystem. These instruments allowed us for the estimate of the magnetic and Coulomb spurious forces acting on the test masses that constitute the mirrors of the interferometer. With these instruments we also had the possibility to study the galactic cosmic-ray short term-term variations as a function of the particle energy and the associated interplanetary disturbances. Platform magnetometers and particle detectors will be also placed on board each LISA S/C. This work reports about an empirical method that allowed us to disentangle the interplanetary and onboard-generated components of the magnetic field by using the LPF magnetometer measurements. Moreover, we estimate the number and fluence of solar energetic particle events expected to be observed with the ESA Next Generation Radiation Monitor during the mission lifetime. An additional cosmic-ray detector, similar to that designed for LPF, in combination with magnetometers, would permit to observe the evolution of recurrent and non-recurrent galactic cosmic-ray variations and associated increases of the interplanetary magnetic field at the transit of high-speed solar wind streams and interplanetary counterparts of coronal mass ejections.

“…The thrusters of this type were used in the Laser Interferometer Space Antenna (LISA Pathfinder) project, see the article in the Acta Astronautica. 169 Extended efforts are now being applied by many research and engineering teams to miniaturize various space assets, to meet urgent expectations of space industry aimed at responding to global challenges. Global information access, distributed orbital networks and exploration of extra-terrestrial bodies for gathering vital information and founding a solid base for their approaching colonization would be among the prime benefits of the efficient low-scale thrust systems.…”

Perspectives, frontiers, and new horizons for plasma-based space electric propulsion

There are a number of pressing problems mankind is facing today that could, at least in part, be resolved by space systems. They include capabilities for fast and far-reaching telecommunication, surveying of resources and climate, and sustaining global information networks, to name but a few. Not surprisingly, increasing efforts are now devoted to building a strong near-Earth satellite infrastructure, with plans to extend the sphere of active life to orbital space and later, to the Moon and Mars if not further. This demands novel and more efficient means of propulsion. At present not only heavy launch systems are still based on thermodynamic principles but satellites and spacecraft still rely on gasbased thrusters or chemical engines to move. Similarly to other transportation systems where electrical platforms expand rapidly, space propulsion technologies are also experiencing a shift towards electric thrusters which do not feature limitations intrinsic to thermodynamic systems. Most important, electric and plasma thrusters promise virtually any impulse ultimately limited by the light speed. Not surprisingly, consolidated efforts in this field could be seen, and all-electric space systems are becoming closer to reality. In this paper we briefly outline the most recent successes in the development of plasma-based space propulsion systems, and present our view on future trends, possibilities and challenges.
