The next two Galileo navigation satellites have now endured the harsh vacuum and temperature extremes of space on the way to their scheduled 28 September launch.
The fourth satellite completed 20 days of thermal vacuum testing at Thales Alenia Space Italy's plant in Rome at the start of June. The third satellite completed the same tests the previous month.
"These two satellites are almost identical to the first two Galileo satellites that were launched last 21 October," explained ESA's Nigel Watts.
