Holes In Martian Moon Mystery

Phobos and Deimos are the only 2 moons of Mars. Both of them have been closely observed and studied. Recently, a new and very intriguing discovery took place on Phobos. Following a couple of studies, scientists have concluded that more than 30 % of the moons interior is empty space. This moon seemed to be unusually light. Phobos is 16.8 miles long and has a craves and lumpy surface. This was the first fascinating aspect of this unique moon.

Many people state that now this feature was presented, Phobos can be a space shuttle stop. Sadly for them, this is not yet been confirmed but surely swipes away the fact that Phobos might have been an asteroid, caught in the gravity of Mars. This fact will lead us to our next step of explanation. Many astrologist's have surmised on what Phobos could have been. Some say asteroids while others have totally different perspectives. No one knows, but scientists are sure the final equation is close. Although this discovery does not tell many physical features, it can throw out some conclusion, such as the asteroid one, stated Tom Andert. Andert is a planetary geophysicist. He personally was a part of this research and gave some valuable information to NASA. What made observing and measuring Mars was the spacecraft named Mars Express. This specific craft left Earth in 2003 and since then was orbiting Mars.

Next, a large group of scientists wanted to find out the density of Phobos.If two objects are the same size, but ones more dense, then it will contain a higher mass. This is the base on which the scientists relied on for their tiny experiment. To find density, you need volume and mass. Due to the fact that they already had the volume, the mass was the missing piece to the final puzzle. They accomplished this by studying the gravitational force of Phobos. Once Mars Express neared Phobos, it was attracted from its gravitational pull. By studying the motion patterns of the spacecraft, they could successfully determine the gravitational pull. With that in their hands, now they had the mass on its way. The density of Phobos 1.87 grams per cubic centimeter. This suggests that Phobos s not made of rocks that can be found on the top of Mars. Therefore, the moon Phobos is not a pure asteroid.

In conclusion, this discovery has presented a whole lot of information to the world and I personally hope they will deploy them to some new discoveries.

Reflection

I truly believe that this discovery can teach the world a lot due to the fact that I have learned a lot from this video.

Here are some of the aspects that remained in my mind after this current event. Firstly, I reminded myself about density,

gravitational pull and other components of astronomy. This was truly perfect revision for me because some of the facts were

flowing away. Secondly, astronomy information also caught my mind. Mars and its complex features caught my attention

so the research really helped me flourish. Finally, information about Phobos and its features also rang a bell in my head.

Researching about them was really intriguing and I can assure you I learned a whole lot. I personally adored this topic and it

was another chance to live my astronomy love. After all, this current event was really interesting and I really enjoyed myself

while I was working.
