13 things you didn’t know about space travel.
1 The first astronauts to Mars may be departing sooner than you realize. In March, President Trump ordered NASA to get people there by 2033, and the agency is building a new rocket known as Space Launch System. It will be one heck of a ride. The heat energy produced by the system’s solid rocket boosters during the two-minute liftoff alone could power 92,000 homes for an entire day.
2 Meanwhile, at least four private companies are racing to be the first commercial taxi service to take paying customers into space: Boeing, Elon Musk’s SpaceX, Jeff Bezos’s Blue Origin, and Richard Branson’s Virgin Galactic. The first flights will most likely be to the near edge of space—more than 100 miles above Earth—where tourists can experience weightlessness and marvel at the view. If you want to take a ride, prepare for sticker shock: Virgin Galactic is selling tickets for $250,000. About 700 people have signed up.
3 Beginning next year, it could be possible to make a cell phone call from space. A German company has teamed with Nokia to build the first 4G network on the moon in 2019. The system will allow astronauts to send videos back home. Other companies are planning satellite constellations that could make the Internet available to everyone on Earth.

Do You Kiss Your Dog? - Find out how gross your questionable habits really are, according to health experts
I admit it, when it comes to food, I have some eeew-inducing practices, like skimming mold off old cheddar and feeding the rest to my unsuspecting family. We're still alive, so how bad can it be? Because our gross human habits fall somewhere along the spectrum from mildly cringeworthy to full-on repulsive, I reached out to experts to find out where some common behaviors land on the gross-o-meter.
What's Ailing Our Doctors? - Today's physicians are burned out and battered by spreadsheets. We patients suffer too.
Today’s physicians are burned out and battered by spreadsheets. We patients suffer too. America's doctors are in crisis. Six in 10 physicians say they're burned out, with burnout rates for some specialties, such as primary care, reaching 70%. When polled by the American Medical Association, 40% of doctors said they were considering leaving their practices in the next two years. Another study, conducted by health-care industry publisher Elsevier, revealed concerns about mental health and burnout: 63% of med students in the United States reported that they had no intention of practicing clinical medicine after graduation and will instead work as lab researchers or academics. This is despite a predicted shortage of 124,000 physicians over the next 10 years.
