NASA makes these images available for public use via The Gateway to Astronaut Photography of Earth. The Image Science & Analysis Laboratory, NASA Johnson Space Center. This is one of NASA's best public outreach programs, in my opinion.

A very big thanks to NASA astronaut/explorer Don Pettit (@astro_Pettit) for taking most of these images. He is one of those explorers who understands how important it is to share the awesomeness he is surrounded by. Not only in these images, but also in the "Science off the Sphere" blog.
The material NASA makes available are still images in sequence, so I downloaded each image from the site mentioned above. Each image was edited using Adobe Lightroom with some cropping to make the stars the focal point of each shot, with manipulation of the contrast to bring out the stars a bit more. I then imported all of the images into iMovie 6, exported as a full quality movie, re-imported and edited to the music.
Music: "Truck out There" by London PM. This song was chosen because for me, this track makes you think you are taking a mellow stroll among the stars. Any good journey requires a great soundtrack. London PM makes great music.

First sequence of star-trails processed using StarStax.
It is a free program created by Markus Enzweiler which allows the processing of time-lapse sequences into star-trails. The first sequence uses the same footage as can be seen between 1:15 and 1:25 on the video, so you can get an idea of the kind of effect that can be created with this software. It is a fantastic program, and if you end up using it, throw a donation his way because he deserves it. I also used his program with some of my star time-lapses, so you can get an idea of what you can do with your own footage.

If anyone has questions about any of the steps I used, I am happy to help teach you.
