Update: The Falcon 9 rocket successfully made it to the floating ocean platform, but suffered a hard landing.

In an daring test, SpaceX will attempt a soft landing of its Falcon 9 rocket on an ocean platform early Saturday morning as part of the company’s plan to develop fully reusable rockets.

SpaceX is all set for its fifth cargo resupply mission to the International Space Station. The Falcon 9 rocket carrying the Dragon spacecraft is scheduled to liftoff from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida on Saturday, Jan. 10 at 4:47 a.m. EST.

Following separation of the Dragon spacecraft from the Falcon 9 first stage, SpaceX will attempt to perform a controlled landing of the rocket on a floating platform at sea. The idea of landing a rocket on an ocean platform is nothing new, but has never been attempted before.

While the private space company has successfully achieved controlled splashdowns of its Falcon 9 rocket in the ocean, this will be the first attempted landing on a floating ocean platform. With past attempts, SpaceX was only able to expect a splashdown with an accuracy within 10 km. During this attempt, SpaceX is aiming to achieve a landing accuracy inside 10 m.

SpaceX hopes to land the rocket on a custom-built floating barge known as the autonomous spaceport drone ship. Spanning 300 by 100 feet, with wings that expand its width to 170 feet, it may sound like a big target, but it is small in comparison to a rocket that towers 14 stories tall and has extensible landing legs that stretch 70 feet.

“The odds of success are not great—perhaps 50% at best,” SpaceX said in a statement posted on their website. “Stabilizing the Falcon 9 first stage for reentry is like trying to balance a rubber broomstick on your hand in the middle of a wind storm,” the statement went on to say.

To assist in the precision landing, SpaceX will use four hypersonic grid fins placed in an X-wing configuration around the rocket. The fins will be deployed upon descent and used to guide the rocket for its landing.

If everything goes as planned SpaceX hopes to fly the recovered Falcon 9 rocket again later this year. This is only one in a series of tests designed with the aim of eventually landing a rocket safely back on dry land.

SpaceX was founded with the objective of dramatically reducing the cost of space exploration through the development of fully and rapidly reusable rockets and spacecrafts. If SpaceX’s attempted rocket landing is successful, it will not only make history, but represent a significant step toward the realization of that goal.

Initially scheduled for launch in December, the mission was delayed to allow for further tests of the of the Falcon 9 rocket before launch. A subsequent launch attempt was scrubbed just minutes before launch on Tuesday morning due to actuator issues on the rocket’s second stage.

NASA and SpaceX will be providing live coverage of the company’s fifth cargo resupply mission to the ISS. NASA’s coverage begins at 3:30 a.m. EST, with SpaceX’s live stream starting at 4:30 a.m. EST.
