It's been a long road for SpaceX's Falcon Heavy. Since plans of its development were first announced in 2011, the project has seen numerous setbacks. Now, the super-sized rocket is finally set to lift off today, February 6, and anyone with an internet connection can watch it in real time.

If it works, Falcon Heavy will make history as the world's most powerful rocket in operation. In what amounts to three of SpaceX's Falcon 9 rockets strapped together, the rocket boasts 27 engines capable of transporting almost 64 metric tons (141,000 pounds) of payload past Earth's atmosphere.

There's a reason no other rocket has been built with that kind of firepower: All those engines need to work in sync in order to produce the 5 million pounds of thrust that will lift the load off the ground. SpaceX CEO Elon Musk has emphasized that the risk of failure is high, even though everything went according to plan in the engine test-fire.

The success of today's launch would change the future of space travel. A rocket capable of carrying such heavy loads could be used to eventually send supplies, habitat modules, and people to Mars. In the short term, it would make shooting heavier satellites into orbit a possibility.

The only extra cargo Falcon Heavy is carrying today is Elon Musk's Tesla roadster. If all goes as planned, the rocket will launch the car into the Hohmann transfer orbit around the sun, which is about equivalent to the distance from our planet to Mars.

Falcon Heavy is scheduled to launch from NASA's Kennedy Space Center in Cape Canaveral, Florida today, February 6, between 1:30 p.m. to 4 p.m. ET. You can catch the livestream of the event at SpaceX's official YouTube channel.

Eau de Space: Former NASA Scientist’s New Perfume Smells Out of This World

Soon, you’ll be able to spritz yourself with perfume that smells like a mixture of gunpowder, seared steak, raspberries, rum, and burned cookies. It’s not Chanel No. 5, but it is the closest you can get to smelling outer space without boarding a rocket.

According to NPR, a new Kickstarter campaign is now producing Eau de Space, a fragrance that NASA developed in 2008 to help astronauts acclimate their noses to the scent of space during training. It was created by Steve Pearce, chemist and founder of Omega Ingredients, a company that produces natural flavors for the food and beverage industry. CNN reports that Pearce concocted his formula based on firsthand descriptions from astronauts, many of whom have agreed that there’s something smoky or burned about outer space's aroma.

NASA has kept the fragrance under wraps for the last 12 years, but Eau de Space product manager Matt Richmond and his team were able to get their hands on it “through sheer determination, grit, a lot of luck, and a couple of Freedom of Information Act (FOIA) requests,” according to the Kickstarter page. They’re ready to share it with the public—and it’s for a good cause, too. Each $29 pledge covers two 4-ounce bottles of Eau de Space: one for you to use as you please, and another to be shipped to a school with a STEM (science, technology, engineering, and mathematics) program.

If you’re eager to support the next generation of space explorers but not keen on smelling like a charred grill yourself, you can donate $15 to the campaign, and the Eau de Space team will ship a bottle to a school without sending one to you. Orders are expected to ship by October 2020, and you can place yours here.
