Not so long ago, in the 16th century, humans understood that the Earth wasn't the center of the Universe. Not more than the Sun! And, if humans dreamt of conquering space for a long time, the adventure just started 60 years ago. The first excursion in space wasn't human but technological. That's how the satellites were born, then the probes... then the first Man on the Moon!
This space conquest sometimes brings up more questions than answers for astrophysicians. It also asks ethical and financial questions: is the space conquest still meaningful today? What is its ecological impact on the Earth, but also on space? What technological innovations did it give us?
