Just two days after launching a Bulgarian communications satellite from Florida, a SpaceX Falcon 9 rocket lifted 10 Iridium NEXT telephone relay stations into orbit Sunday after a foggy afternoon launch from California.
Despite blustery winds and high seas, the California rocket builder also was able to recover the booster's first stage with a pinpoint landing on an off-shore droneship, SpaceX's 13th successful landing in a row.
More important for Iridium, it was the second batch of 10 Iridium NEXT spacecraft successfully launched by SpaceX under contracts with the satellite telephone provider to deploy 75 of the 81 relay stations being built to replace the company's current fleet of aging first-generation spacecraft.
"Now that we're into the launch phase after more than seven years of effort, we're poised to complete the replacement transformation of our very unique network through a total of eight launches spread over a very short 18 months," Iridium CEO Matthew Desch told reporters last week.
