It is one of the defining events in history: on the 21st of July 1969 at 02:56:20 GMT, Neil Armstrong stepped onto the Moon and was joined a few minutes later by Buzz Aldrin. For a brief moment in time, the Apollo 11 mission united people from all over the world in a way that nothing else ever had. Everyone of a certain age remembers exactly where they were when they heard the words, "The Eagle has landed."

As America celebrates its 233rd birthday this holiday weekend, there will be an extra light in the sky along with the fireworks. Across the country, Americans will be treated to spectacular views of the International Space Station as it orbits 220 miles above Earth. Many locations will have unusually long sighting opportunities of as much as five minutes, weather permitting, as the station flies almost directly overhead.

Saharan dust formed giant arcs off the west coast of Africa on July 1, 2009. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite took this natural-color picture the same day. The camel-colored dust forms a series of arcs, one east of Cape Verde, one west of the archipelago, and one to the south. The dust plume nearest the coast is both the smallest and most concentrated.

"Pachube is a web service available at http://www.pachube.com that enables people to tag and share real time sensor & environmental data from objects, devices, buildings and spaces around the world. The key aim is to facilitate interaction between remote environments, both physical and virtual. Apart from enabling direct connections between any two responsive environments, it can also be used to facilitate many-to-many connections: just like a physical "patch bay" (or telephone switchboard) Pachube enables any participating project to "plug-in" to any other participating project in real time. Think of it as a generalized real time broker for networked objects and environments that helps you build the Internet of Things."
