NASA pinning down 'here' better than ever

Before our Global Positioning System (GPS) navigation devices can tell us where we are, the satellites that make up the GPS need to know exactly where they are. For that, they rely on a network of sites that serve as "you are here" signs planted throughout the world. The catch is, the sites don't sit still because they're on a planet that isn't at rest, yet modern measurements require more and more accuracy in pinpointing where "here" is.

THEMIS celebrates 5 years of watching aurora and space weather

People still talk about the launch. It was the first – and so far, only – time NASA has launched five satellites at one time. Carefully balanced inside a Delta II rocket, the five THEMIS (short for Timed History of Events and Macroscale Interactions during Substorms) spacecraft were launched into space from Cape Canaveral at 6:01 p.m. ET on February 17, 2007. The spacecraft were nestled in a ring shape, four around the outside and one on a middle pedestal.

Landsat 5 Suspension of Operations Extended

Landsat 5 Earth imaging operations have been suspended for an additional 90 days while the U.S. Geological Survey Flight Operations Team (FOT) continues to investigate options for the resumption of imaging. Landsat 5 imaging was halted in November 2011 when an electronic component vital to transmission of the satellite's Thematic Mapper (TM) data began showing signs of imminent failure.

New Satellite Technology a Possible ‘Game Changer’ for Communications

As the interoperability discussion continues, so does the frustration of many who have worked on this issue for decades but haven’t seen their goals realized. So it makes sense to take a look into the future of what could be bright spot, given the right circumstances, some money and a will to make it work. Satellite technology has proven itself during major events but its limitations are known.
