Update: SpaceX has postponed the landing until tomorrow out of an "abundance of caution." The original story is below.
SpaceX will attempt another rocket launch Thursday night, making this the private spaceflight company's fifth launch this year.
Once the Falcon 9 rocket is on its way to high-elliptical orbit, the company will begin a landing phase for its engines and main fuel tank — the Falcon 9's first stage. Just like its last landing attempt, this will be difficult thanks to the extreme velocities (not to mention extreme heat) during re-entry.
This will be the third time in two months that SpaceX will try to land the rocket on a barge, affectionately named the "Of Course I Still Love You" droneship. These landings are part of SpaceX's efforts to make reusable rockets, reducing the cost of getting to space.
You can watch tonight's launch and landing right here (the video embedded at the top of the page) or on SpaceX's site. Liftoff is scheduled for 5:40 p.m. Eastern.
