Artemis II uncovers evidence the Moon isn’t dead after all
After Artemis II’s lunar flyby and splashdown, onboard instruments detected a transient outgassing event near the Aristarchus Plateau that thickened the Moon’s exosphere and produced a faint glow, complemented by spikes in noble gases. If verified, this could be the strongest evidence yet of present-day lunar activity, guiding future landers and missions to study lunar volatiles and surface processes.
