    11-21-12: On this episode of the Daily Orbit, Curiosity gears up to spend Thanksgiving on Mars, scientists have created a nano-nose to help sniff out explosives, and the tropics might not be exactly the paradise you expected.

    Emerald Robinson: Who could soon be reading your email? What's most better than a dog? Well, a dog's nose. And a celebrating Thanksgiving Martian style. All that and more, coming up on the Daily Orbit.

    Hello and welcome to the Daily Orbit! I am Emerald Robinson. We are celebrating Thanksgiving Martian style. Here at the Daily Orbit we are thankful for Curiosity and all we are learning about Mars. Our happy little rover Curiosity is headed to the lake for Thanksgiving Point Lake on Mars, that is. For it's thanksgiving activities the rover plans to use its Mast Camera to examine possible routes and targets to the East.

    And instead of carving the turkey the rover will be using its hammering drill to carve a rock to collect samples of powder from rock interiors. JPL says that the team is getting comfortable with the more complex operation planning as this will be its first touch and go on the same day.

    Curiosity just left its Rocknest location where it's been sitting for weeks and it carrying soil samples it gathered there. Happy Martian Thanksgiving little rover. I wouldn't recommend eating that turkey.

    Things we are not thankful for? More surveillance on the Internet. So be careful little fingers what you type if passed a Senate bill amending the Electronic Communications Privacy Act of 1986 would permit law enforcement to peek into your email, all social networking like Facebook and Twitter and other online communication without the requirement of a warrant first. But if it's any consolation, they do have to notify you if they check out your account anywhere between 3 to 365 days later.

    A dog's nose is a thousand times better at picking up scents than a human is sparking a new project that uses nanotechnology to replicate the same sort of old factory sensors inside a dog's snout. Not only can it pick even the faintest of vapors but it can distinguish one scent from another.

    The idea is to use this electronic nose in the detection of explosives. According to engineers like humans dog have their good days and bad days. The electronic nose would be a more reliable bomb detector. However, engineers say that the nose could have other applications such as in detecting disease particles in someone's breath or identifying food that has spoiled. Better the electronic nose the me.

    Where you don't want to live if you want a really long and healthy life? The Tropics. A new report entitled the State of the Tropics gives insight into life expectancy of those who live in tropical region. Although, having significantly improved over the last 50 years, the average life expectancy for a person living in the tropics is 64.

    4 years. 7.

    7 years shorter than the rest of the world. But that's up significantly from 23 years shorter in 1950. Wow!

    The report indicates that the difference in longevity stems from conflict, disease, lack of food and poverty. Another positive from the report? Infant mortality is down from 161 deaths per 1000 to 58. Infant mortality averages 33 per 1000 in the rest of the world. Nearly 40% of the world's population reside in the tropics making is a very critical region. Researchers say that the topic had geopolitical economic and strategic importance and sooner or later will have to take this seriously.

    And our week won't be complete without a report on greenhouse gases. The World Meteorological Organization is reportedly we hit a record high level of greenhouse gases in 2011. The carbon dioxide level grew by 2 parts per million reaching a number of 40% about the pre-industrial level. Methane and nitrous oxide increased by about .

    3% in 2011. Nitrous oxide has an impact on global warming 298 times greater than carbon dioxide. This Thanksgiving I would be very thankful if we can get its greenhouse gas thing under control and we won't have to bring you anymore bad greenhouse gas news.

    Well, that's it for today's Daily Orbit. We at the Daily Orbit are very thankful that we are watching and hope you have a happy Thanksgiving. Gobble, gobble.
