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.
