Life in the universe is a fascinating topic. The simplest question: Are we alone? It breeds so many deeper and more profound scientific questions, like “How many habitable planets are there?” “How likely is life to develop on any given planet?” and “How long can a civilization survive?” We can’t answer them definitively, but we can narrow it down. The Drake equation, shown above, was first developed by Frank Drake, the head of the Search for Extraterrestrial Intelligence (SETI), in 1961. He took the question of are we alone and made it quantifiable, in a probabilistic way. It lets us...
Since 1998, when construction began on the International Space Station, 400 Km above our heads, it has undergone significant changes. It makes sense since it takes a long time to build anything in space, nonetheless a multi-million dollar space research laboratory. Watch the video from NASA’s Johnson Space Centre, and see how quickly parts of the station move, change, and are relocated as the station reaches it’s current glory. It truly is a marvel of science, engineering, and technology. Watch closely at 1:57 as the Canadian made Special Purpose Dextrous Manipulator (SPDM, colloquially DEXTRE) unit is installed. A bit of pride for my...
