UPDATED 08/28/15 with information from the European Space Agency. The two European Galileo navigation satellites for Arianespace’s next mission from French Guiana have been fueled at the Spaceport, readying them for integration with their Soyuz launcher. Galileo full operational capability (FOC) satellites 9 and 10 were “topped off” during activity this week at the Spaceport’s S3B payload preparation facility, further advancing preparations for the Sept. 10 mission —... read more

Galileo’s Two Newest Birds Undergoing Initial Checks

March 30, 2015By

The two newest Galileo satellites — dubbed Adam and Anastasia — launched Friday are now being checked out by the European Space Agency (ESA) and France’s CNES space agency from the CNES Toulouse centre. Following these initial checks, the two satellites will be handed over to the Galileo Control Centre in Oberpfaffenhofen, Germany, and the Galileo in-orbit testing facility in Redu,... read more

Soyuz in the Launch Zone for March 27 Galileo Launch

March 24, 2015By

The Soyuz for Arianespace’s next medium-lift mission is in the launch zone at French Guiana, where it stands ready to receive the two spacecraft passengers that will join Europe’s Galileo global navigation satellite system. Applying procedures that have been followed since the workhorse Soyuz launcher inaugurated the Space Age, the basic three-stage vehicle for Arianespace’s March 27 flight emerged today from its MIK integration building in... read more

Arianespace-March-O

The third and fourth Galileo Full Operational Capability (FOC) satellites are a confirmed “fit” for their Arianespace Soyuz launch March 27, having made initial contact with the mission’s dual-payload dispenser in French Guiana, according to Arianespace. The fit check was completed over a two-day period inside the Spaceport’s S1A payload preparation building. The two satellites were installed separately, with the... read more

2, 4, 6, 8 — Who Do We Appreciate?

January 29, 2015By

Galileo, that’s who! For dogged determination and persistent pushing-forwardness in the face of adversity, obstacles, and the occasional technical difficulty. That there may be occasional confusion, as well, or mixed messages as to just what the future may bring, is certainly understandable. In fact, it is to be expected, given the circumstances. Let’s review the math. Two Two for the... read more

Galileo FOC Anomaly Traced to Design Ambiguity, Says Inquiry Board

October 8, 2014By

The root cause of the anomaly that sent two Galileo satellites into the wrong orbit is a shortcoming in the system thermal analysis performed during stage design, and not an operator error during stage assembly, according to findings by an independent inquiry board. The Independent Inquiry Board was formed to analyze the causes of the anomaly occurring during the orbital injection of satellites... read more

Improper Fuel Line Installation Led to Incorrect Galileo Orbit

October 6, 2014By

The cause of two Galileo satellites being released into the wrong orbit August 22 can be traced to improper installation of a hydrazine fuel line, according to Space News and the GalileoGNSS blog. The hydrazine fuel line was installed too close to a supercold helium line on the Fregat upper stage, which caused the hydrazine to freeze long enough to upset the Fregat stage’s orientation... read more
