SpaceX Has Received Permission From the US Government To Launch Elon Musk's Car Toward Mars (businessinsider.com)
SpaceX this week is preparing to launch Falcon Heavy, the biggest rocket in the company's history, for the first time. From a report: The 230-foot-tall three-booster launcher is scheduled to blast off Tuesday between 1:30 and 4:30 p.m. ET. SpaceX says Falcon Heavy is the most powerful rocket in the world. SpaceX's founder, Elon Musk, wanted this test launch to happen as early as 2013, though he recently said it could end in an explosion. Instead of putting a standard "mass simulator" or dummy payload atop Falcon Heavy, Musk -- who once launched a wheel of cheese into orbit -- will put his personal 2008 midnight-cherry-red Tesla Roadster on top of the monster rocket. In an Instagram post over the weekend, Musk also revealed that the car would carry a dummy driver, which Musk is calling "Starman," wearing a SpaceX space suit. "Test flights of new rockets usually contain mass simulators in the form of concrete or steel blocks. That seemed extremely boring," Musk said in an Instagram post in December, adding that the company "decided to send something unusual, something that made us feel." However, all rocket payloads need a permit from the Federal Aviation Administration to launch, and Musk's sleek electric car is no exception. The FAA granted SpaceX that permission on Friday in a staunchly formal notice, which Keith Cowing posted on NASA Watch.
But it is much, much cheaper than the Saturn V. It's also twice as powerful than anything else flying today.
I was curios at how Musk's rocket stacked up to the rocket that sent us to the moon. From New Atlas:
the two-stage Falcon Heavy has nine Merlin 1D main engines in each of its first stage elements burning supercooled liquid oxygen and kerosene to produce 5,548,500 lb of thrust. Then the second stage takes over with its single Merlin 1D engine to punch 210,000 lb of thrust
That's remarkable when compared to the Atlas and Ariane rockets of today, but now let's look at the Saturn V. Its S-IC first stage has five Rocketdyne F1 engines that, when set loose, generate a staggering 7,610,000 lb of thrust as it burns kerosene and liquid oxygen.
Then comes the S-II second stage with its five Rocketdyne J-2 putting out 1,155,800 lb of thrust from a mix of liquid oxygen and liquid hydrogen. But where Falcon Heavy has already used up its stages, the Saturn still has its S-IVB third stage and its single J-2 engine that can manage a respectable 225,000 lb of thrust.
Lots of other interesting information in the article such as size of payload and cost.
