Moving charges produce magnetic fields. Since thermal transients produce an electric current, thermal transients produce magnetic fields. It has been shown that the generation of these magnetic fields in the vicinity of sensitive instruments leads to a degradation of recorded data.

Getting closer to a theoretical solution and to an effective mitigation technique will help magnetic missions in ESA’s Science programme, Earth Observation programme and, in fact, all missions that employ magnetic-sensitive sensors.

This study aimed to develop a framework for studying the effects of spacetime curvature on the propagation of quantum states of light, and to compare them with the propagation of classical light. When distributing entangled photon pairs through a gravitational potential, the effect of spacetime curvature on the properties of quantum states can become significant. This could be relevant for plans to use satellites for global quantum key distribution.

Magnetometers are fundamental instruments used in planetary and space science. They are able to measure magnetic fields originating in a planet’s interior, past fields encapsulated in rocks in the crust, as well as magnetic fields generated by the motion of charged particles in the plasma environments of ionospheres, magnetospheres and interplanetary space.

There is an increasing need for ever smaller pulse-tube coolers. These coolers have the characteristics necessary for space applications because the absence of moving parts in the cold finger makes them extremely reliable and any induced vibrations are typically smaller and easier to control.

But these types of cooler are less efficient and have a lower power density. Typically, this is resolved by increasing their drive frequency, to reduce amplitudes and displacements, which means that the coolers are smaller

Testing the validity of general relativity at cosmological and microscopic scales is a challenging open question. The impediment at cosmological scales is our lack of understanding of dark matter and dark energy. At microscopic scales, it is the unknown effect of gravity on quantum mechanics. Recently, space based matter wave interferometers have been proposed as candidates for addressing certain aspects of both these problems.

XIPE is designed to be launched with a VEGA-C vehicle into an orbit of 550 km and <6° inclination. With this orbit, eclipses last about 35 minutes. Due to remaining spacecraft fragments the mission is planned to end by controlled re-entry. The baseline ground station is Kourou either for S/S or S/X telemetry band, albeit Malindi (or Singapore) is additionally available, if necessary, for additional downloading capability in case of particularly bright sources. The mission duration is 3+2 years.

Thales Alenia Space

In several applications it is relevant to quantify the energy exchanges for a system embedded in an electromagnetic field, and to solve the typical equations of electromagnetic fluid dynamics. In order to model such systems, several approximations are usually adopted because of the diculty (in some cases, impossibility) to solve, even numerically, the electromagnetic fluid dynamics equations.

UNIV BARI

The RC-SIM project is enclosed in the initiative of using more extensively the capability of the radio communication signals (telemetry and datalinks) of interplanetary probes for remote sensing the structure of planets and moons. In more detail, the objectives of this study are:

-Investigate the physical parameters that can be obtained from the use, as a remote sensing instrument, of the radio communication systems on-board interplanetary probes.

GMV

This report reviews the recently completed and current work programs on various aspects of hypersonic aerodynamics research conducted in European research organisations. Four main fields are covered: configuration aerodynamics, propulsion aerodynamics, rarefied flows and associated non-equilibrium effects, and real gas effects. In each field, a brief description or comment appears on each job, together with references to published papers, a job index and an address for each contributor.
