In a new study, it has come to notice that the presence of astronauts on the moon has caused unexpected warming in the subsurface of the moon for a period in the 1970s. This new study has dined after delving into the lost tapes from the Apollo missions.
In the year 1971 and 1972, NASA has placed sensors on the moon, and it was done during the Apollo 15 and 17 missions. This was done to measure the moon’s surface and subsurface temperatures, and they are a project dubbed which are dubbed the flow of heat experiment.
The data which was collected and sent back to Earth until 1977 and the Scientists were baffled by the gradual warming of the moon’s surface, and the sensors are reading it. NASA has already abandoned this research, and it was done due to the lack of funding, and it is only some of the tapes which were archived, and it is with the others that assumed to be lost and leave the scientists who are unable to analyze it further for future.
These missing tapes which were found recently are present in the National Archives, and it has been said by the co-author of the study Walter Kiefer, who is the senior staff scientists at the Lunar andPlanetary Institute. He along with his team has spent many years by recovering and interpreting the data which are to pinpoint the source of the warming.
The moon has two different types of rocks which areanorthosite and basalt. Anorthosite is usually light in color, and it makes moon bright while basalt is common on Earth and it is darker, and it appears as the maria or sea on the moon. Light colored usually surfaces more energy which is outward, and it dies while darker surfaces which absorb energy.
We can use the photos which are from an extremely high-resolution camera which is aboard the Lunar Reconnaissance Orbiter (LRO), and it orbits the moon, and the scientists have determined that as the astronauts have walked or drove on the moon and it has disturbed the anorthosite lunar soil.
