IRF's instrument SARA observes mini-magnetosphere above lunar magnetic anomaly
Scientists from the Swedish Institute of Space Physics (IRF) have observed a mini-magnetosphere above a lunar magnetic anomaly using observations of energetic neutral atoms from the satellite instrument SARA (Sub‐keV Atom Reflecting Analyzer) on the Indian Chandrayaan‐1 spacecraft. Together with colleagues from India, Switzerland and Japan, the IRF scientists have published their results in this week's issue of Geophysical Research Letters
. An image of the lunar magnetic anomaly in backscattered atoms is displayed on the cover
of the journal (vol. 37, no. 5).
"A mini-magnetosphere is a new class of object," says lead author Martin Wieser, IRF, "and observations from the IRF-led instrument SARA demonstrate a new technique for studying airless bodies - imaging in backscattered neutral atoms."
