Although this pocket of protection exists when the moon is outside of the magnetosphere, researchers believe the effects are still due to Earth\u2019s magnetic field.<\/p>\n<p>An anomalous dip in particle counts When the research team analyzed data taken from the Lunar Lander Neutron and Dosimetry (LND), onboard China\u2019s Chang\u2019E-4 lander, they were surprised to find that the LND experienced a 20% dip in GCR particles hitting detectors while the lander was on the moon\u2019s far side. This occurred at a specific time during the lunar \u201cmorning\u201d and only for about 2 days each lunar cycle. Since the LND took data over 31 cycles, the team could see that this was not just a one-off occurrence. This was unexpected because it was previously assumed that GCRs are evenly distributed in the space between Earth and the moon, outside Earth\u2019s magnetosphere.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>High-energy particles called galactic cosmic rays (GCRs) bombard unprotected objects in space, often causing damage.
