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
