I was laying flat on my back on the living room sofa, surfing TV-channels. Two guys appeared on screen, replacing their kayaks with tiny rubber canoes which were better suited to the shallow water of a river. After a while, though, they ended up walking, legs dry above their ankles, searching for a way out […]Read More A journey I’ve never made (yet)
Loading new images of a full Moon rising over the Ostrobothnia countryside fueled my imagination. What would I see in the sky if I could make the planet Trappist-1d change places with the Earth? In the compact planet system around the ultra-cool brown dwarf star Trappist-1, the neighbour planets are almost within reach. Ok. Not exactly […]Read More Combining imagination and mathematics improves understanding
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?
The Mars Pathfinder robotic Rover, Sojourner, was the first vehicle landed to explore another planet. That happened July 4th, 1997. Until today, four rovers have successfully been operated on the surface of our red neighbour planet. March 10th, 2016, the Mars Reconnaissance Orbiter had kept a close eye at Mars for ten years. March 14th, 2016, the ExoMars […]Read More How about visiting another world
A satellite in Low Eart Orbit, LEO, can cover just one certain area of the Earth’s surface at a time. The same thing goes when it comes to contacting the satellite. To download data from the satellite, or to send commands to the satellite is possible only during the few minutes each orbit it passes right […]Read More ‘SpaceDataHighway’ – Why and How?
Most of our satellites orbit the Earth – either in Low Earth Orbit, LEO, Medium Earth Orbit, or in Geostationary Orbit, GEO. The closer to the Earth a satellite is the shorter its period. So – What if the satellite is even further away than the geostationary satellites? Why would you place satellites that far […]Read More Satellites in extraordinary orbits
Friday, November 13th, at a conference, Professor Hannu Koskinen, gave a speech about space as an almost infinite source of surprises. Being a part of the Rosetta team, he reminded the audience about comments on the first images showing the duck-shaped comet 67P/Chyryumov-Gerasimenko. The images of Pluto, captured by New Horizons, also were more surprising […]Read More Prepare for surprises
Wherever you are early November you can see our closest planet, Venus, glimmering in the morning sky. Sometimes it appears as a morning star, sometimes like a bright evening star. Asteres planetai was the term used in ancient Greece before anyone got clues enough to build up a knowledge about these wandering stars. Now Venus […]Read More To Venus with (love?)
“It’s beautiful!” Ok. That is reason enough to look at the dark sky. But, of course, there’s more to it. The good thing is that there is a lot more you can find out about the solar system just by looking at the moon and our closest planets with the naked eye! The image above […]Read More Have a look – and see
I imagine, there might be drivers who look at speed limits as suggestions. There might as well be drivers, perhaps even male drivers, that see speed limits as suggesting a minimum speed. On facebook, people write about a flash of light out of the blue sky when they got caught by a speed camera along […]Read More Breaking the law
