In the next few days, a rover launched by China’s space agency is scheduled to land on the Moon. It’ll be the first spacecraft to touchdown on lunar soil in almost 40 years. So what might a Chinese space rover be looking for on a dusty rock we haven’t been to since the Bee Gees were still topping the charts? And it’s Friday, which means time to play Silicon Tally, the game where Marketplace Tech host Ben Johnson and a worthy adversary try and stump each other with numbers from the week’s tech news.

Tonight, around midnight, you may see some nerds running around in cloaks and bare feet. The destination will be the movie theater of course, for the first showing of “The Hobbit: The Desolation of Smaug.” The film promises to be full of special effects — not all of them visual. There are a lucky few who will be watching the movie in theaters fitted with new speaker technology from Dolby called Atmos. Plus, an IP troll targets Germans who watch porn online. And, the challenges facing Adobe after a security leak last month exposed usernames and passwords.

Today the World Health Organization releases its annual report on malaria. The disease kills some 600 thousand people every year — most of them in Sub-Saharan Africa. Part of fighting any disease is understanding how populations move. And there’s a tech device now being used to tackle this challenge. It’s called a cell phone. Plus, 3-D printed guns. And, should surgeons wear Google Glass in the operating room?

If there is one vehicular tech promise that has captured our imagination for decades but never quite been delivered, it’s the jetpack. From Jules Verne to James Bond, we’ve pretended these things are just around the corner. But for some reason, we don’t have them yet — until now. New Zealand’s Martin Jetpack hopes to rekindle our interest and bring us closer to our dreams. Plus, should computer coding be a required subject for kids in school? And, the latest NSA leaks reveal the government is spying on massive online multiplayer games like “World of Warcraft” and “Second Life.”

Today the NASA Advisory Council holds a meeting. The name of the committee? Human Exploration and Operations. The topic will be what’s next for human space exploration. Right now the answer seems to be Mars, but the first step is heading back toward the Moon on the planned Orion Space craft for a practice run. The exercise involves capturing an asteroid with some funny-sounding technology. Plus, Germany’s police are using an app to track neo-Nazis. And, this week’s Techsplainer.

Marketplace Tech concludes our Mind Games series this week with another look at the intersection of video games and mental health. You may remember yesterday we went to University of Southern California, where they’re building virtual reality programs for soldiers with post-traumatic stress disorder. Today we’re going to a VA hospital in New York City where these programs are being administered.

Today, lawmakers in the House are voting on a bill that could fight the growing problem of patent trolls. Some estimates put the annual cost of patent lawsuits at $80 billion. The Innovation Act could help put a dent in that. It has support from tons of tech companies. In an ever-updating society where consumers are constant targets of tech marketing, it’s no wonder we’ve developed quite an appetite for replacing the old with the latest and greatest. But a new study from Yale University out this week says a lot of the precious ingredients of our consumer technology is kind of irreplaceable. And, in today’s Mind Games, how video games are being used to treat PTSD.

Electronic cigarettes are getting more popular all the time. Which may be why more places are starting to put more restrictions on the technology. Today in New York, the City Council is considering whether to restrict e-cigarettes just like regular cigarettes–banning their use in offices, in restaurants, and on beaches. The more technology kids interact with, the more adults want to set some controls on that interaction. New options do abound. One of the latest from a company called FiLIP: a smartwatch that lets parents control who the kid calls, among other things. And, the latest Mind Games, Marketplace Tech’s series on video games and mental health.

This week we’re looking at the intersection of video games and mental health. Yesterday we talked to a game designer; tomorrow we’ll talk to a researcher. Today we’re going to hear from an occupational therapist. Amanda Foran works with children and adults who are on the Autism spectrum at Motion Therapy in Rockville, Md. She’s found that video games — played by both people on and off the spectrum — can help build social interaction skills.
