The first answer coming to mind is simply “Why not?”. But – There’s a lot more to it. First of all, teachers should be updated on space science. We all should. It’s not an easy task, though. Just reading the news about space science and space technology takes time. Understanding the basic concept often takes […]Read More Why bring space into the classroom?
Our climate is a complex phenomenon. In the atmosphere, there is about 0,04% carbon dioxide. The discussions about the climate, though, could be up to 100% about carbon dioxide. Thinking it over once more, you’ll find that this tiny amount of carbon dioxide, CO2, is easier to double than the 21% oxygen in the Earth’s atmosphere. Burning […]Read More Observing the Earth’s climate 2/2
We breathe and we eat. Oxygen and carbohydrates. Oxygenator and fuel. One key ingredient to life on Earth is photosynthesis. To keep an eye on the Earth’s health, we have to monitor the photosynthesis. And – Our planet is an ocean planet, so we start our journey at sea. The Baltic Sea. The picture shows an […]Read More Observing the Earth’s climate 1/2

It is said, investigated and confirmed that we tend to react more strongly to news about some rapid, violent event than to news about something changing very slowly over a long time. We do so even if we […]Read More Earth Observation – special cases
Imagine observations of our home planet, worldwide, being continuously updated – without satellites. Is that even possible? Our planet is changing – although the changes are tiny -; the human population is both growing and changing in a way that causes large resources to be needed in few dense areas. By using satellites as our […]Read More Earth observations by satellite.
