Space missions and experiments have become a field of research as we acknowledge new discoveries with every trip to space . Human advancement in space and related technology in the late 50’s led to sending satellites in space and later in the late 60’s landing on the Moon opened new phases for human understanding of space. Since then humans have achieved new advancement in the technologies and the machine which has opened many of these new operations. Landing on the moon was a great step for humans to understand their ability to travel to different planets too. Spacex is coming up with their idea of sending manned spacecraft to Mars in the early 20’s . It Is expected to carry astronauts by 2024 and are planning a full setup forming base for humans.
But as we know the last mission which landed on the moon was dated Dec 17 1972 . Various other astronauts have made a moon walk and left their remains as footprints still present on the surface of the moon. Eugene Cernan and Harrison Smitt hold the record to be the last men walking on the moon. This mission accomplished the longest moonwalk and collected more than 500 samples of this lunar soil. They covered a distance of 20 miles with the help of a lunar rover, collecting samples and understanding terrain, while driving around. The remains or the marks of their journey till remains as we see through satellite. Due to absence of winds , there is no phenomenon which could move or distort those marks. NASA high resonance cameras recorded those prints present there after more than 3 and a half decades since the last landing on the moon. In 2009 .
But some other picture depicting the marks of footprints shocked the scientists as soon as they saw them. These were more than the size of a normal human being and were following a trail depicting a proper moment over the surface. It is just like we leave a trail on the deserts , but due to wind it gets hidden or distorted. But on the moon the scenario is different but the marks remain forever as there is no wind to distort them. It was interesting to notice these movements or marks since they were present about “30 miles from the landing site, while humans have never travelled on the surface of moon for more than 20 miles.”
But since we do question the existence of life in space , scientists were interested to know what could be the reasons for those if not humans or Aliens. So they came up with the thoughts like :
- They could be due to meteors which do hit and Impact the surface of the moon. But still doubted as the occurrence is in a straight line . While meteors and asteroids do hit and make craters which we see, but not a line.
- Other scientists came up with a belief that these could be a tube of lava. We know that there are a number of volcanoes on the surface of moons. Scientists believe that there is still lava present inside the surface and is still running causing lava tubes to form . We could come up with this observation as is the case on earth and there are various tubes through which lava still flows.
- These tubes are supposed to be as long as several kilometers under the surface of the moon.
There could be many other beliefs of scientists, but the belief in tubes, if it is there, can be beneficial for humans to set up their base on the moon. It is believed to be strong, tough and resistant from external damage. This could be safe from the radiations and also provide suitable temperatures for humans. Along with those would also save from meteors which do fall frequently on the surface. But it could be an issue of concentration, since we know that lava still flows underground through this tube and we are not sure that these caves are dead or not, so it could be an area of concern if we do reach the moon and set up base in them.
“The unusual activities or observations do bring out the fascination of humans to know about thee. The major field humans are working on is to find life in space, and observations like these do keep those expectations alive.But if not, we do find out something new every time which could help us in near future, in understanding space. And thus making our future travel and trips more secure . “
