Mars’ Atmospheric Loss

According to NASA, billions year ago there is liquid water in Martian surface. Today Mars is dry, cool and a dead planet. The Martian atmosphere is very thin today (almost 1% of the Earth atmosphere). Billions year ago Martian atmosphere was not so thin.

NASA’s recent study has found a reason for this. The reason is Solar Wind. Normally the planet with a developed magnetic field can protect its atmosphere from Solar Wind. But Mars’ magnetic field is became off billions years ago, so its atmosphere became heavily exposed by Solar Wind. Mars atmosphere is stripping away by Solar Wind and became very thin now.

Spot The Station

Many times I thought that if I see moon on the sky then why not the human made space satellites from earth? I find the answer when I search a little bit about NASA and its projects. The answer is yes; we can see International Space Station from earth with our naked eye. Naked eye? When I first read this, it was hard to believe. International Space Station is the second brightest think on evening or morning sky after moon. You can see it from middle of a city. It is bright enough to see with our naked eye. When sun light reflects from it and come to our eyes, we can see it. This is the same reason of why we see moon.

The Martian

The Martian

My World Space Week has gone well. Just saw ‘The Martian’. I like the movie. If you interested in Space Science and Research, then you will like this movie. The movie is based on the Science Fiction novel named The Martian written by Andy Weir. The acting is very good. The direction is good. Scientific facts are shown almost accurately. The space is shown marvellously in this movie. I will give this movie 4 stars out of 5.

After watching this movie, you will feel that how we are blessed to live in Earth. We should take care of our home planet. We should take care the resources which helps our life.

Read more about this movie on Wikipedia and watch the official trailer on YouTube.

International Space Station

This is the World Space Week. In this week many countries including countries from Europe and Asia are celebrating space science and technology and how it can be used for more human kind.

Yesterday I was reading about ‘International Space Station’ (ISS) mainly on Wikipedia and watching some videos on YouTube. I found ISS very interesting. The space station has been continuously occupied since November 2000. In that time, more than 200 people from 15 countries have visited. The objective of ISS is to continue research on space (like Moon and Mars), research on Physics, Biology, Microgravity etc.
