CAPE CANAVERAL SPACE FORCE STATION -- SpaceX is set to send up two European Commission's Galileo navigation satellites on Tuesday night, however, weather might be an issue.

The Falcon 9 rocket is expected to send up the Galileo L13 mission from Space Launch Complex 40 at Cape Canaveral Space Force Station, SpaceX stated.

The launch is set at 6:50 p.m. ET, but going up on time is a concern.

The 45th Weather Squadron is giving a 40% chance of good liftoff conditions, with the only worries being the surface electric fields, cumulus cloud and anvil cloud rules.

If the launch is scrubbed, the next chance will be Wednesday at 6:46 p.m. ET.

This is the 22nd mission for the Falcon 9's first-stage booster B1067. With its amazing career, it has two crewed missions under its hat.

"Following stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean," explained SpaceX.

These satellites are Europe's global navigation satellite system, which is similar to GPS, but better, according to the European Commission.

"Galileo is four times more accurate than GPS providing 1 meter (3 feet) accuracy and a broad range of services," stated the commission.

These two satellites will join the 28 of its mechanical siblings at a medium Earth orbit of 14,429 miles (23,222 kilometers), according to the European Space Agency.

The Galileo satellites are used for smartphones, smartwatches, vehicles, and drones, among other things.

The Galileo satellites are under civilian control and funded and owned by the European Union.
