An introduction to LEND research, continued The LEND instrument records the number of neutrons detected each second, along with latitude, longitude, altitude, angle, and more. Using these data, scientists have mapped the surface of the moon to visually depict regions that deviate from the “normal” neutron counts.

It had been previously theorized that lunar water would be found in the form of ice in Permanently Shadowed Regions (PSRs). LEND maps disagree: LEND Research Project South Pole PSRs

Hypothesis: Variations in neutron flux are caused by thermal variations from the solar insolation and lack of lunar atmosphere. Test: Average LEND data by time of lunar day to determine whether temperature variations affect the flux of thermal neutrons. LEND Research Project

Original maps used only latitude and longitude, working with ~1,000 squares to capture data: LEND Research Project

How to capture time of lunar day (28 Earth days) in addition to squares? Bin each longitude region: LEND Research Project Days 1, 8, 15… Days 2, 9, 16… Days 3, 10, 17… Days 4, 11, 18…

My colleague Jerry and I created: 9 latitude bands 24 longitude bands Roughly 40 “time bins” per lat/lon square With 3,000 to 6,000 data points per lat/lon/time bin. LEND Research Project

Q: Do we see the expected dependence on temperature of thermal neutrons detected? To answer this, we plot thermal neutron counts for each lunar hour: LEND Research Project

Q: Do we see the expected dependence on temperature of thermal neutrons detected? A: Yes. And something else. LEND Research Project

Conclusion Temperature variations do play some part in thermal neutron flux from the lunar surface.

Conclusion Temperature variations do play some part in thermal neutron flux from the lunar surface. ( And also: Hydrogen’s behavior on the lunar surface is still not well understood.

What is the Lunar Exploration Neutron Detector? One of six instruments on NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft Launched in 2009 with an est. cost of $600 million. LEND was developed in cooperation with the Russian Space Research Insitute (IKI).

These bins make it relatively easy to study other significant questions, such as: Q. Does the earth’s magnetosphere shield the moon from GCRs? We can now compare data from full moon time bins with data in time bins outside the full moons. LEND Research Project

Q: Does the earth’s magnetosphere shield the moon from GCRs? A: Our results, essentially “No”, are consistent with established theories and of primary interest to lunar and cosmic ray scientists. LEND Research Project
