At 4:10 p.m. ET on April 14, SpaceX will launch a 22-story-tall Falcon9 rocket from Cape Canaveral carrying its Dragon space capsule full of supplies for the astronauts living on board the International Space Station (ISS).
The main event will come a few minutes after the launch, though. The spaceflight community will watch with baited breath as SpaceX attempts to guide the rocket back to Earth and land it upright on a platform in the ocean.
This feat would be a game-changer for spaceflight and would be a huge step toward making reusable rockets a reality. The ability to use the same rockets over and over would considerably reduce the cost of launches and space travel itself.
After the launch, the first stage of the rocket separates and then thrusters flip on to reorient the rocket and point it back towards Earth. Grid fins deploy just before the rocket reenters Earth's atmosphere and a sophisticated GPS tracking system guides the rocket to its landing spot.

If all goes according to plan, the rocket will land upright, similar to this video of the concept that SpaceX created:
