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.

The Orionid Meteor Shower Peaks This Weekend

October is always a great month for skywatching. If you missed the Draconids, the first meteor shower of the month, don't despair: the Orionids peak this weekend. If you've ever wanted to get into skywatching, this is your chance.

The Orionids is the second of two meteor showers caused by the debris field left by the comet Halley. (The other is the Eta Aquarids, which appear in May.) The showers are named for the constellation Orion, from which they seem to originate.

The shower is expected to peak overnight from Sunday, October 21, to Monday, October 22, when you can plan to see 15 to 20 super-fast meteors per hour. The best time for viewing is between 2 a.m. and 5 a.m., when Orion appears completely above the horizon. Make a late-night picnic of the occasion, because it takes about an hour for your eyes to adjust to the darkness. Bring a blanket and a bottle of wine, lay out and take in the open skies, and let nature do the rest.

There's a chance that the Moon might interfere with the meteors' visibility, according to Space.com. Leading up to its full state on October 24, the Moon will be in a waxing gibbous phase, becoming larger and brighter in the sky as the Orionids speed past Earth. Limiting light pollution where you can—such as by avoiding city lights—will help.

If clouds interfere with your Orionids experience, don't fret. There will be another meteor shower, the Leonids, in November, and the greatest of them all in December: the Geminids.

How the Hubble Space Telescope Helped the Fight Against Breast Cancer

The beauty of scientific research is that scientists never really know where a particular development might lead. Research on Gila monster venom has led to the invention of medication that helps manage type 2 diabetes, and enzymes discovered in the hot springs of Yellowstone National Park are now widely used for DNA replication, a technique used by forensic scientists to analyze crime scenes.

The same rule of thumb applies to NASA scientists, whose work has found dozens of applications outside of space exploration—especially in medicine.

Take the Hubble Space Telescope. Launched in 1990, the Hubble has graced us with stunning, intimate photographs of our solar system. But it wasn't always that way—when the telescope was launched, the first images beamed back to earth were awfully fuzzy. The image processing techniques NASA created to solve this problem not only sharpened Hubble's photos, but also had an unexpected benefit: Making mammograms more accurate.

As NASA reports, "When applied to mammograms, software techniques developed to increase the dynamic range and spatial resolution of Hubble's initially blurry images allowed doctors to spot smaller calcifications than they could before, leading to earlier detection and treatment."

That's because the Hubble Space Telescope contains a technology called Charge-Coupled Devices, or CCDs, which are basically electron-trapping gizmos capable of digitizing beams of light. Today, CCDs allow "doctors to analyze the tissue by stereotactic biopsy, which requires a needle rather than surgery," NASA says [PDF]. Back in 1994, NASA predicted that this advancement could reduce national health care costs by approximately $1 billion every year.

And that's just one of the tools NASA has developed that's now being used to fight breast cancer. When cancer researcher Dr. Susan Love was having trouble studying breast ducts—where breast cancer often originates—she turned to research coming out of NASA's Jet Propulsion Laboratory. As Rosalie Chan reports for the Daily Beast, the Jet Propulsion Lab has dedicated vast resources to avoiding the spread of earthly contaminants in space, and its research has included the development of a genomic sequencing technology that is "clean and able to analyze microscopic levels of biomass." As Dr. Love discovered, the same technology is a fantastic way to test for cancer-linked microorganisms in breast duct tissue.

A second technology developed at NASA's Jet Propulsion Laboratory—the Quantum Well Infrared Photodetector, or QWIP—enables humans to see invisible infrared light in a spectrum of colors, helping scientists discover caves on Mars and study volcanic emissions here on Earth. But it's also useful at the doctor's office: A QWIP medical sensor can detect tiny changes in the breast's blood flow—a sign of cancer—extremely early.

And as any doctor will tell you, that's huge: The earlier cancer is detected, the greater a person's chance of survival.
