SpaceX debuts world’s most powerful rocket, sends Tesla into solar systemFebruary 7, 2018 Stephen Clark

SpaceX ground crews also placed a Hot Wheels model Roadster on the car’s dash, with a mini-Starman inside. An “Arch” data storage device placed inside the car contains a copy of Isaac Asimov’s “Foundation” novels, and a plaque on the attach fitting between the Falcon Heavy upper stage and the Tesla is etched with the names of more than 6,000 SpaceX employees. (...)
If its first stage boosters are not recovered, SpaceX’s Falcon Heavy is capable of delivering up to 140,660 pounds (63,800 kilograms) to low Earth orbit when launched to the east from Florida’s Space Coast, where rockets get a velocity boost from Earth’s rotation. (...)
“We’ll be doing several Falcon Heavy missions per year,” he said. “So let’s say there’s a big national security satellite that’s due for launch in three or four years. We’ll probably have a dozen or more launches done by then … I don’t think there be a launch number that’s going to inhibit our national security stuff.”
But going into Tuesday’s demo flight, only three more Falcon Heavy missions were confirmed in SpaceX’s backlog: Two for commercial telecom companies Arabsat and ViaSat, and one as a test flight for the Air Force codenamed STP-2. Another company, Inmarsat, has an option to launch a future satellite on a Falcon Heavy. (...)

The data show that when the Tesla finally climbs out of the Earth-moon gravity well its velocity — reflected in a number known as C3 — will be 12 kilometers squared per second squared, which translates into a speed of about 3.5 kilometers per second, or 6,700 mph faster than Earth’s velocity as they both orbit the sun.
That excess velocity, provided by the upper stage’s final rocket firing, is what will enable the Tesla to leave Earth’s gravitational clutches and move out into the solar system, a point the Roadster will reach Sunday.
It will pass within about 69 million miles of Mars on June 8 and cross the red planet’s orbit in July before reaching its farthest distance from the sun — about 158 million miles — on Nov. 19.After that, the Roadster and Starman will fall back toward the inner solar system, picking up speed as they near the low point of the orbit, or perihelion, on Sept. 1, 2019. Perihelion in this case roughly matches the distance of Earth’s orbit from the sun, the Tesla’s starting point. The Roadster then will head back out along the same path, traveling a now-familiar route over and over again for the foreseeable future.
Musk has said he likes to imagine the Tesla remaining in orbit for hundreds of millions of years if not longer. But McDowell said two forces acting on the car will limit its lifetime.
One is Jupiter. The giant planet’s gravity perturbs bodies in the asteroid belt and, over time, will have an effect on the Tesla’s trajectory. The other effect is a subtle acceleration produced by tiny temperature-related forces over extremely long periods that also would act to change the orbit.
“It’s tiny, but over timescales of millions of years it’s enough to shrink the orbit and make the thing fall into the sun,” McDowell said. “So it’s a race between does that happen before some Jupiter perturbation ejects it from the system.
“On timescales of centuries, it’s going to be pretty much in the orbit it’s in now. On timescales of thousands of years, it’s going to be in a not-horribly-different orbit, but Jupiter will mess it around some. And then on timescales of millions of years, it won’t be there anymore.” (...)
