During its brief visit, the lander also dropped off several scientific payloads on the lunar service, including the European Space Agency's Negative Ions at the Lunar Surface (NILS) instrument.
We have collected an amount and quality of data far beyond our expectations.
Unlike positively charged particles, negative ions never make it back into orbit, forcing scientists to study them on the lunar surface instead.
These observations on the Moon will help us better understand the surface environment and act as a pa."
