Mars expeditions have been one of the most interesting ones, as there are quite a few theories and speculations about the planet that have been chalked out by specialists, capitalizing on sheer imagination. National Aeronautics and Space Administration (NASA) posted a picture of a mysterious hole on the surface of the Red Planet, which evidently raised the interest of many.
The image shows a mysterious hole, known as the Pavonis Mons volcano on Mars, and the dusty slopes surrounding the edges of the volcano. Mars Reconnaissance Orbiter, a HiRise instrument currently circling the Red Planet has been the one to click the picture. The opening of the hole is stated to be about 35 meters, while the depth underneath is assumed to be around 20 meters.
The reason this picture has created such hype in the scientific world is due to the possibility of containing life. These Martians pits are often regarded as good candidates for containing life, especially in the interiors of the caves, which is a relatively safer position for nurturing life from that of the harsh surface of Mars.
Another reason for being interested in these holes on the surface of Mars is that these very holes are targetted for possible future missions, through spacecraft, robots to even human interplanetary explorers. NASA disclosed the reason for such a hype surrounding a hole located on the surface of the Red Planet has been thoroughly explained by NASA in a blog posted on the 1st of March, this year.
Mars is the fourth planet of our Solar System circling the Sun. After quite a few journeys made to the planet, the environment of Mars was disclosed to be desert-like, dusty and cold, having a very thin atmosphere. However, it also revealed that the Red Planet was once warmer, wetter and had a denser atmosphere, approximately billions of years ago.
This unusual hole or the Pavonis Mons volcano on Mars was first discovered in the year 2011 and was posted recently by NASA. The full extent of the Pavonis Mons volcano on Mars is still being studied, along with the circular crater to be seen around the hole.
Mars is recorded to be the most explored planet to date, and both India and the European Space Agency (ESA), each have their spacecraft orbiting around the planet. Whereas, NASA took the tally to another level having 3 spacecraft in its orbit, one lander and one rover on the surface monitoring the Red Planet for a better explanation.
