A planned launch by the company has been canceled for the second day in a row.
The launch of the second generation of the constellation was delayed due to thick clouds and strong winds.
That has now turned into a 48 hour push, as bad weathernixed today's attempt as well.
We were hopeful that weather conditions would improve for liftoff, but unfortunately we are standing down from today's attempt. The time is Eastern.
You can watch the Saturday attempt, which will include a landing of the first stage of the Falcon 9 at Cape Canaveral shortly after liftoff. 15 to 20 minutes before liftoff is when the SpaceX broadcasts start.
There are pictures of the evolution of the rockets.
There is an 80% chance of good weather at Cape Canaveral on Saturday, with winds at liftoff and upper-level wind shear as the only concerns.
The Italian Space Agency, the Italian Ministry of Defense, and the Italian Ministry of Education, Universities and Scientific Research collaborated on the project. The system consists of two satellites.
The first of those satellites was launched in December. The spacecraft is in a sun-synchronous polar orbit with an altitude of over 400 miles. When it gets off the ground, it will head for the same path.
