The launch date will change, but the game plan remains the same. Thaicom 8 will lift off atop SpaceX's two-stage Falcon 9 rocket. A few minutes into flight, the rocket's two stages will separate; the second stage will carry Thaicom 8 to orbit, while the first stage will come back down and attempt to land on "Of Course I Still Love You," one of SpaceX's two "autonomous spaceport drone ships," which will be stationed several hundred miles 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 6,600-lb. Thaicom 8 satellite is headed to a distant supersynchronous transfer orbit; because of that long trip, the Falcon 9 first stage will be traveling very fast when it comes back down to Earth.

However, a Falcon 9 first stage pulled off a similarly difficult ocean landing earlier this month, during the launch of the JCSAT-14 communications satellite to geostationary transfer orbit.

That May 6 milestone was the second ocean touchdown for SpaceX; a Falcon 9 also landed successfully on "Of Course I Still Love You" last month, during the launch of the company's robotic Dragon cargo capsule to the International Space Station for NASA.

SpaceX also has one terra-firma touchdown to its name: In December, a Falcon 9 landed back at Cape Canaveral, during the launch of 11 satellites for SpaceX customer Orbcomm.

These landings are part of SpaceX's effort to develop reusable rockets, a technology that company founder and CEO Elon Musk has said could slash the cost of spaceflight by a factor of 100.
