The space sector is a rapidly growing market with unique requirements for high-quality manufacturing and magnetic measurements.
This seminar will focus on magnetic challenges and considerations in the design and manufacture of spacecraft, as well as the role of magnetics in space applications and missions. Speakers from industry and academia will cover subjects including magnetic cleanliness, attitude control and propulsion systems, in addition to talks on magnetic aspects of the JUICE, SWARM and Solar Orbiter missions.
The programme is being developed, and there’ll be more details as they’re finalised.
- Dr Graeme Finch, NPL
- Dr Ellie Galanis, Paragraf Ltd
- Mr Olivier Masseglia, Bartington Instruments Ltd
The dress code for the event is business attire / smart casual.
The Use of Magnets in Ion Thrusters for the Coming Mega Satellite Constellations
by Charlie Ryan of University of Southampton
There are various planned mega constellations of satellites that will be launched over the next several years. These constellations of thousands of satellites require significant orbit raising, station keeping and end of life deorbiting, requirements that are beyond conventional chemical propulsion. Consequently they are using ion thrusters, in particular hall thrusters, which operate through the application of magnetic and electrostatic fields to a plasma. This talk will outline how magnets are essential to the operation of these ion thrusters, and helping to herald a step change in spacecraft engineering.
Design Drivers for Spacecraft Magnetometers, in particular ESA'a JUICE mission to Jupiter
by Patrick Brown of Imperial College
Magnetometer instruments have been flown on many space missions over the years due to their wide scope of scientific applications covering everything from Earth field mapping, planetary, magnetospheric and solar physics to interplanetary shocks and fundamental plasma physics. Our laboratory at the Blackett Laboratory has over 50 years of history in the development and operation of highly accurate DC magnetometers in space. I will present the design drivers for magnetometers on different missions, how the scientific goals drive the spacecraft EMC condition and describe the design and performance of our magnetometers with particular focus on the upcoming European Space Agency JUICE mission to the Jovian system.
Frenetic Magnetic – Examples of Magnetic Fields in Space!
by Barry Kellett of RAL Space
My talk is actually the first half of a one hour talk. The full talk covers a “journey” from the Earth to the heart of very active galaxies called quasars. However, today I will only cover the first half of the journey from the Earth via the Moon and then the gas giant planets. Then to the Sun and the discovery of sunspots and the Sun’s magnetic cycle and ending with some of my own work on a very special and unusual magnetic star – CU Virginis!
Solar Orbiter: Magnetic Control & Verification
by Max Pudney of Airbus
Solar Orbiter is an ESA mission to investigate how the Sun creates and controls the heliosphere. It will travel within the orbit of Mercury and take pictures of the Sun closer than ever before, including over polar regions. The magnetic field is critical to how the Sun controls the heliosphere, and measurements provide imperative data that allows particle measurements at the spacecraft location to be linked to events seen on the Solar surface, helping to answer key outstanding questions. To ensure the spacecraft itself does not interfere with these measurements, a magnetic cleanliness programme was followed on Solar Orbiter. This talk will discuss some of the design choices, controls during integration, analysis and verification performed to ensure the magnetic measurements are capturing what’s happening in space and not what’s happening on the spacecraft!
AC Magnetic Field Verification Methods Used in Space Applications and Missions
by Christian Trenkel & Dongsheng Zhao of Airbus & ESA
A new method for the verification of AC magnetic field requirements has recently been developed. In the first part of the talk, the fundamental theoretical principles underlying the new method will be presented, together with a description of how these principles have been applied to the design of the new method. In the second part of the talk, the complete setup including the hardware, the software and the test procedure are presented. The data post-processing is explained, and special attention is given to the good practice that ensures a good measurement.
