Fifty years ago today, the US launched its first satellite, Explorer 1. JPL, a major NASA center in Pasadena, CA, put up a cool website with lots of pictures, audio, video, etc. to commemorate the event, available here.
And don't forget, tomorrow morning before dawn Venus and Jupiter will be very close to each other on the sky.
