Overcoming a dynamic and stormy weather pattern in Central Florida, SpaceX launched a Falcon 9 rocket from Cape Canaveral with the Israeli-owned Amos 17 commercial communications satellite Tuesday at 7:23 p.m. EDT (2323 GMT).

Two key pieces of hardware needed for NASA’s next Mars rover — an Atlas rocket booster and sterile components of the rover’s sample collection system — recently arrived at Cape Canaveral ahead of the mission’s scheduled launch July 17.

United Launch Alliance said Monday it did not submit a proposal in a competition to launch a U.S. Air Force GPS navigation satellite, apparently relinquishing the contract to rival SpaceX, the only other company certified to launch the mission.
