Earth's magnetic field, our protection against solar radiation, varies from one place to another and in time as well.
Similar to a boat that moves through water, the solar wind flow is affected by the presence of the Earth. The Earth's magnetic field contains a space filled with particles from terrestrial origin.
The Earth is protected against corpuscular radiation by its magnetic field. This protective bubble around the Earth is the magnetosphere.
Due to a weak greenhouse effect the average temperature is about -63°C with huge differences between day and night.
Satellite for the study of the chemical composition of the atmosphere in interaction with the surface of Mars.
The absence of plate tectonics and the very little volcanic activity are important to understand why Mars has a far smaller greenhouse effect than Earth.
The atmosphere of Mars does not have a protective ozone layer and contains 30 times less water vapour than Earth's atmosphere.
Since methane on Earth is linked to microorganisms, methane measurements on Mars might lead to traces of past life.
What type of water is found and what is the amount of water present in the atmosphere of Mars?
Short fact note on the temperature, diameter, pressure, mountains, gravitation, natural satellites and the elements that give Mars' atmosphere its red colour.
For the design, the manufacturing and the usage of atmosphere measuring devices one needs electronics, mechanics, software, computing and technical skills.
Transitional zone between space and the completely different atmospheric layers closer to the ground.
In radio detection of meteors, reflected radio waves provide information about the trajectory, speed and mass of shooting stars.
The three most active meteor showers: Perseids (in August), Geminids (in December) and Quadrantids (in January).
The visible phenomenon due to the flight of a meteoroid, a particle of debris in the Solar System, through the atmosphere is called a meteor.
