Exploring Space
The BBC has created a monster infographic illustrating “every attempt to leave Earth’s orbit and reach a destination in extraterrestrial space – be it with probes, orbiters, rovers, or of course manned missions.”
The graphic shows successful and failed missions, country of launch origin and type of mission (eg., fly-by, rover, actual landing).
