Today’s momentous Falcon Heavy launch is history in the making, and could finally mark the beginning of sending human crews not just back to the moon, but all the way to Mars. Today’s launch, if all goes well, will send a Tesla Roadster into orbit near Mars. As SpaceX explained: “Falcon Heavy was designed from the outset to carry humans into space and restores the possibility of flying missions with crew to the Moon or Mars.” Below you’ll see photos from SpaceX that illustrate each stage of the launch, as they appear in SpaceX’s animation video above. This will help you understand what’s happening during today’s launch, so you can follow along fully informed. First, you’ll see the mission timeline, and the next section will show each stage of the launch illustrated by photos.
The Falcon Heavy Mission Timeline
Here is the schedule of what is supposed to happen today after the launch, according to SpaceX. All times are approximate and mark minutes before the launch and then minutes after the launch. The launch is scheduled to begin at 1:30 p.m. Eastern, but the launch window is open until 4 pm. Eastern.

The Falcon Heavy Launch Stages in Pictures
First, the Falcon Heavy will take off from the Kennedy Space Center. This is scheduled to occur at 1:30 p.m. Eastern today, but the launch window is open until 4 p.m. If the weather doesn’t hold or if something delays it, they can try again tomorrow.
This animation below shows the Falcon Heavy launching from the Kennedy Space Center.
You’ll see it take off, going far, far away.
First, the two side boosters will separate from the center core. When they separate, they’ll flip and initiate a boostback burn to return to Cape Canaveral Air Force Station.
These side boosters will return to their landing sites for future reuse.
Here they are, returning to Earth.
These two will land at Cape Canaveral Air Force Station.
Next, the third booster, the center core, will separate.
The center core will return for reuse, landing on a drone ship in the Atlantic Ocean. It will also perform a boostback, but it won’t have enough fuel to return to land. That’s why it’s landing on the Autonomous Spaceport Drone Ship (ASDS), nicknamed Of Course I Still Love You.
Yes, you read that correctly. This one will land on an autonomous spaceport drone ship (ASDS) in the Atlantic Ocean. This ship is called “Of Course I Still Love You.”

After the three booster stages touch back on Earth, we will move on to the next stage. The mission will continue on an experimental long coast and third stage two burn. The long coast could last six hours through the Van Allen radiation belts. This leaves more things to chance, such as the fuel possibly freezing, oxygen vaporizing, and other issues that could hurt the rocket’s ability to reach trans-Mars injection. Problems at that stage might mean that the Roadster doesn’t escape Earth’s orbit but burns up in the atmosphere instead. Or it might just end up orbiting Earth for a while.
If the coast stage is successful, the Roadster will then separate from the upper stage, targeting a heliocentric orbit. In other words, it will orbit the sun and be in close proximity to Mars during certain points of its orbit. The rocket’s payload stage will pop off the fairing’s two halves, exposing the Tesla Roadster. Yes, a bright red Tesla is indeed being sent off into space.
This Tesla is fitted where the payload, such as customer satellites, would normally go.
According to SpaceX’s animation, the Tesla Roadster will then coast in hyperbolic orbit to Mars at about seven miles per second. The Tesla won’t actually get as close to Mars as this animation shows. And it will be carry
“It will be in an elliptical orbit with one part of the ellipse being at Earth orbit and one part being at Mars orbit, so it will essentially be an Earth–Mars cycler,” Musk said to Florida Today. “We estimate it’ll be in that orbit for several hundred million years, maybe even in excess of a billion years.”

The car will eventually travel even beyond Mars. And it’s carrying three cameras, so we might see some pretty amazing photos.
