Sending a Tesla to Mars

SpaceX's big new rocket blasted off Tuesday on its first test flight, carrying a red sports car aiming for an endless road trip past Mars.

The Falcon Heavy rose from the same launch pad used by NASA nearly 50 years ago to send men to the moon. With liftoff, the Heavy became the most powerful rocket in use today, doubling the liftoff punch of its closest competitor.

The three boosters and 27 engines roared to life at Kennedy Space Center, as thousands jammed surrounding beaches, bridges and roads to watch the rocket soar, delayed more than two hours by high wind.

Two of the boosters were recycled and programmed to return for a simultaneous touchdown at Cape Canaveral, while the third, brand new, set its sights on an ocean platform some 300 miles offshore.

SpaceX chief executive Elon Musk owns the rocketing Tesla Roadster, which is shooting for a solar orbit that will reach all the way to Mars. As head of the electric carmaker Tesla, he combined his passions to add a dramatic flair to the Heavy's long-awaited inaugural flight. Typical ballast for a rocket debut: concrete or steel slabs, or experiments.

The Heavy is intended for massive satellites, like those used by the U.S. military and major-league communication companies. Even before the test flight, customers were signed up.

Given the high stakes and high drama, Tuesday's launch attracted huge crowds not seen since NASA's last space shuttle flight seven years ago. While the shuttles had more liftoff muscle than the Heavy, the all-time leaders in both size and might were NASA's Saturn V rockets, which first flew astronauts to the moon in 1968.

Not counting Apollo moon buggies, the Roadster is the first automobile to speed right off the planet.

At the convertible's wheel is SpaceX's "Starman," a dummy in a white-and-black-trimmed spacesuit, and on the soundtrack is another nod to David Bowie: his 1969, pre-Apollo 11 song "Space Oddity," featuring the memorable line "Ground Control to Major Tom." SpaceX is hoping for live shots of the car from on-board cameras, once the protective enclosure comes off and the car sails off fully exposed.

The Heavy already is rattling the launch market. Its sticker price is $90 million, less than one-tenth the estimated cost of NASA's Space Launch System megarocket in development for moon and Mars expeditions.

SpaceX has decided against flying passengers on the Heavy, Musk told reporters Monday, and instead will accelerate development of an even bigger rocket to accommodate deep-space crews. His ultimate goal is to establish a city on Mars.
