Why SpaceX's Falcon Heavy Is Such a Big Deal
SpaceX unveils its most powerful rocket.
SpaceX has given the world a first look at its most powerful rocket yet - the Falcon Heavy. Not only is this beast the most powerful rocket that the Elon Musk-led SpaceX ever made, it will be “the most powerful operational rocket in the world by a factor of two,” according to their site. When it launches with its initial cargo, its destination will be the orbit of Mars, according to Musk. Eventually, the rocket might be the one to carry humans to the Red Planet as well.
Sharing the rocket’s photos and video on Twitter and Instagram, SpaceX put the space vehicle's might in perspective, saying it’s equal to eighteen 747 aircraft “at full power”.
"With more than 5 million pounds of thrust at liftoff — equal to approximately eighteen 747 aircraft at full power — Falcon Heavy will be the most powerful operational rocket in the world by a factor of two," SpaceX reps wrote.
To get that 5 million pounds of thrust and liftoff, the two-stage rocket has 27 first-stage Merlin engines, as states SpaceX. That’s three times as many engines as are on SpaceX’s current workhorse rocket - the Falcon 9.
In fact, the first stage for the Falcon Heavy essentially involves three Falcon 9 cores strapped together. The reusable boosters will get it into orbit, then fly back to Earth and land vertically like other Falcon 9s. The second stage will be powered by just one Merlin engine, same as the Falcon 9.
Here is the Falcon Heavy getting vertical:

Most people think human extinction would be bad. These people aren't philosophers.
- A new opinion piece in The New York Times argues that humanity is so horrible to other forms of life that our extinction wouldn't be all that bad, morally speaking.
- The author, Dr. Todd May, is a philosopher who is known for advising the writers of The Good Place.
- The idea of human extinction is a big one, with lots of disagreement on its moral value.
Picking up where we left off a year ago, a conversation about the homeostatic imperative as it plays out in everything from bacteria to pharmaceutical companies—and how the marvelous apparatus of the human mind also gets us into all kinds of trouble.
- "Prior to nervous systems: no mind, no consciousness, no intention in the full sense of the term. After nervous systems, gradually we ascend to this possibility of having to this possibility of having minds, having consciousness, and having reasoning that allows us to arrive at some of these very interesting decisions."
- "We are fragile culturally and socially…but life is fragile to begin with. All that it takes is a little bit of bad luck in the management of those supports, and you're cooked…you can actually be cooked—with global warming!"
