October 5th marks the birthday of Robert H. Goddard – one of the most important figures in the history of human space exploration and the man whom @NASAGoddard is named after. Goddard was more than a talented physicist, inventor and engineer – he was a visionary who turned concept into action, launching the world's first liquid-fueled rocket in 1926. The giant leaps made in human spaceflight over the last century would not have occurred without his many technical developments and theoretical contributions. #AProudSalute to Robert H. Goddard, the man who ushered in the Space Age!

For centuries, lighthouses have served a critically important safety and navigational role for ships and planes on and over water – and their beacons illuminate the way for travelers to this day. From the Atlantic and Pacific Coasts, to the Gulf, to the Great Lakes, America has over 700 lighthouses. Even the Statue of Liberty served as a lighthouse for several years. Amazing structures with an important history! #NationalLighthouseDay
