Spaceflight magnetic-field measurements are often contaminated by interference from the host spacecraft. We present a new dataset to enable the development and testing of interference mitigation schemes for spaceflight magnetic-field data. Over 100 h of data, including laboratory-generated proxies for magnetic interference and geophysical signals, have been produced. A ground truth for the underlying interference is also provided, enabling the rigorous quantification of data-cleaning techniques.

Demonstrating the space flight capability of the next generation of precise, reliable magnetic field instruments is important for enabling future space science missions that will further our understanding of the connection between Earth's magnetic field and the Sun. Here, we present a new magnetic field instrument design called Tesseract, the results from its successful first space flight demonstration aboard a rocket, and its measurements of magnetic fields associated with the aurora.

We present the experimental results of a new copper-based alloy suitable for use in high-precision magnetic sensing. It outperforms by providing lower magnetic noise and superior power consumption. Prototype sensors constructed from this material can meet an exacting standard, the 2012 1 s INTERMAGNET standard, for magnetic observatories.

The Swarm-Echo Satellite carries two magnetometers that allow us to obtain two independent measurements of the changes that occur in the Earth's magnetic field during events such as aurora. Magnetometers must be independently calibrated to ensure they remain accurate. If no magnetic reference is available, a model magnetic field must be used. This paper discusses the method used to calibrate the magnetometers on Swarm-Echo and shows the improvements the calibration has made to the data product.

The ability to make reliable magnetic measurements in space is very important for a broad range of applications in space science. Here, we present the design and performance of a new magnetometer that looks very promising for making stable reliable magnetic measurements in space. We show that Tesseract performs better than the traditional ring-core design in metrics that are associated with stability.
