Cool! There's a reason for it:
Today is NASA's 50th birthday! 
On July 29, 1958, President Eisenhower signed the bill that established the National Aeronautics and Space Administration.
Ike was also the primary architect of NASA, as it was originally conceived. He insisted that it be a civilian agency, not part of the military; and he insisted that it be a builder and developer, not just a political stunt. He favored steady growth, building space stations and the vehicles to get people there, always with an eye on the moon and Mars, but establishing an enduring infrastructure along the way.
(Ike was big on establishing a solid infrastructure. It worked well for him in World War II and as a president. That's why we have the interstate highway system today. It's probably also why the Union Jack flies over London today instead of the swastika.)
Of course, all that changed when President Kennedy changed NASA's mission to land a man on the moon "because nothing we could do in this decade will be more impressive to mankind or more expensive to achive."
Then came the glory days of the U.S. space program. Sadly,
sic transit gloria mundi.
