SpaceX postponed the satellite launch of a rocket that would attempt to land on a ship at sea for a third time Thursday, NBC News reported.
The launch was postponed until Friday, because of a “tiny glitch in the upper stage engine actuator," SpaceX CEO Elon Musk tweeted.
The Thaicom-8 commercial communications satellite will lift off atop SpaceX’s two-stage Falcon 9 rocket. After the rocket’s two stages separate, the second one will carry Thaicom-8 to orbit. The first one will come back and try to land on one of SpaceX’s two drone ships stationed off the Florida coast.

"As with other missions going to geostationary orbits, the first-stage will be subject to extreme velocities and re-entry heating, making a successful landing," SpaceX wrote in a statement.
The landings are part of SpaceX’s effort to develop usable rockets.
