Moon erosion by solar wind far less than expected finds lunar rock study

The Moon's fragile exosphere, a sparse envelope of gas surrounding the lunar body, is mainly generated by interactions between the Moon's surface and external forces. Until now, scientists believed the solar wind played a major role in this process. But new research led by Vienna University of Technology (TU Wien) challenges that assumption.
