A new study which was done researchers shows that the presence of astronauts on the moon has already caused unexpected warming in the subsurface of the moon for a period which is during the 1970s. This study has helped in delving the lost tapes from the Apollo missions.
In the year 1971-72, NASA has planted some sensors on the moon, and it was done during the Apollo 15 and 17 missions. This was done so that they can measure the moon’s surface and the temperature of the subsurface of the moon and the project was dubbed the flow of the heat experiment.
The data was collected, and it was sent back to Earth which is until 1977, and the scientists were shocked by the gradual warming of the surface of the moon. Those sensors read the temperatures which are seen a by the scientist. NASA has already abandoned the research, and the main reason behind the abandonment of this is said to be lack of funding. This was only some tapes which are archived, and it is with the others that are assumed to be lost, and it leaves the scientists who all are unable to analyze it further in the future.
Recently, these missing tapes are found, and they are present in the National Archives. The co-author of the study, Walter Keifer has said this, and he is the senior staff scientists working at the Lunar and Planetary Institute. He with his team has carried many studies to extract the data by interpreting it and to pinpoint the source of the warming.
The moon is said to have two different types of rocks which include anorthosite and basalt. Anorthosite is light in color, and it makes the moon bright, and basalt is common on the surface of Earth, and it is darker. Light color rocks emit energy which is outward, and dark color surfaces absorb energy. To use the photos which are from an extremely high-resolution camera, this is aboard the Lunar Reconnaissance Orbiter, and it orbits around the moon.
