The radiation detectors and magnetometer were searching for lunar magnetic and radiation fields similar to the [[Van Allen radiation belt]] around Earth, sending information about once every minute<ref name="ReferenceA"/> until its last transmission which came about {{convert|55|km}} away from the lunar surface.{{Sfn|Harvey|2007|p=32}} Although it did prove previous measurements of the Van Allen radiation belts that were taken from ''Luna 1'' around the Earth,{{Sfn|Harvey|2007|p=32}} it was not able to detect any type of radiation belts around the Moon{{Sfn|Harvey|2007|p=34}} at or beyond the limits of its magnetometer's sensitivity (2–3x10<sup>−4</sup> [[Gauss (unit)|G]]).<ref name=SP99>{{cite book|date=1966|title=Significant Achievements in Planetology 1958–1964|location=Washington D.C. |publisher=NASA|oclc=30740240 |page=43}}</ref>

''Luna 2'' showed time variations in the [[electric flux|electron flux]] and [[energy spectrum]] in the Van Allen radiation belt.{{sfn|Hendrickx|2010|p=128}} Using [[ion trap]]s on board, the satellite made the first direct measurement of [[solar wind]] flux from outside the Earth's [[magnetosphere]].{{sfn|Ogurtsov|Jalkanen|Lindholm|Veretenenko|2015|p=35}} On its approach to the lunar surface, the probe did not detect any notable [[magnetic field]] to within {{convert|55|km|mi}} from the Moon.{{Sfn|Siddiqi|2002|p=23}}{{Sfn|Harvey|2007|p=32}} It also did not detect a radiation belt around the Moon, but the four ion traps measured an increase in the ion particle flux at an altitude of {{convert|8000|km|mi}}, which suggested the presence of an ionosphere. The probe generated scientific data that was printed on {{convert|14|km|mi}} of [[Teleprinter|teletype]], which were analysed and published in the spring of 1960.{{Sfn|Harvey|2007|p=34}}
