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.

‘Solar System’ information

You probably know that NASA found real water flowing sign on ‘Marc’ surface. I was just searching the internet about that news. I found a good website with information related to our ‘Solar System’. The website is created by NASA. The important thing is, the information is for common people and written in a very interesting way. You can find basic information about all the planets in our ‘Solar System’. This is a very good resource for kids also.

I found this very interesting and want to share with my readers.
