NASA Fermi: You Won't Like Me When I'm Angry

Gamma rays helped turn Bruce Banner into the Incredible Hulk

The Hubble isn't the only telescope floating in orbit around earth - NASA also has the Fermi Gamma Ray Telescope. Fermi turns five this week.

Why gamma rays? The visible light that we see is a small part of a much larger electromagnetic spectrum. The Fermi telescope uses gamma rays, which travel very fast with a very high energy (i.e. they have a high frequency). Faster, high energy waves have a better chance of detecting hard-to-see objects in the universe such as black holes. Check out the following description of the spectrum from Science Company.

Electromagnetic Spectrum

The chart makes it apparent that lower energy light on the left of the visible spectrum such as radio, microwave, and infrared are what we see in our everyday lives.  Several of these waves are passing through your body as you read this, but since they are low energy no damage is done. The higher energy gamma rays on the right can only be used safely because the Fermi telescope is in space, away from human contact.

From the NASA Fermi mission site:

The Large Area Telescope (LAT), the mission's main instrument, scans the entire sky every three hours. The state-of-the-art detector has sharper vision, a wider field of view, and covers a broader energy range than any similar instrument previously flown.
Fermi's secondary instrument, the Gamma-ray Burst Monitor (GBM), sees all of the sky at any instant, except the portion blocked by Earth. This all-sky coverage lets Fermi detect more gamma-ray bursts, and over a broader energy range, than any other mission. These explosions, the most powerful in the universe, are thought to accompany the birth of new stellar-mass black holes.

Check out a five year retrospective of the Fermi telescope below.

All this news makes the Incredible Hulk happy, and he celebrates by beating the mess out of Loki in this scene from the Avengers movie.

Wu-Tang and Science Are For The Children

I love science. I love rap. The Science Genius B.A.T.T.L.E.S. (Bring Attention to Transforming Teaching, Learning and Engagement in Science) competition combines both science and rap gracefully.  Teams write raps about science topics such as DNA structure. Kids learn science within the competitive spirit and creativity of hip hop culture.  

Best of all, the Wu-Tang's GZA is one of the judges. He's been involved with other science initiatives with astrophysicist Neil deGrasse Tyson, which I blogged about earlier.

Many of songs are are included on RapGenius which you can find here.

NPR's Code Switch blog has a great quote which sums up my feelings about STEM education.

"Not every student is going to be a straight-A student, and go on to college and declare a science major and be the next Einstein," he says. "But through this project we definitely are going to have more scientifically literate young people."

A Curious Year for NASA

Curiosity Rover's First Anniversary  (201308060002HQ)

When you think about government accomplishments in the past year, many of NASA's achievements get overlooked. As entertaining as constant partisan deadlock between the legislative and executive branches can be, let's not forget about our tech success! Despite the end of the space shuttle program, NASA has been steadily moving toward exploring space.

This week marks a year since NASA landed the Curiosity rover on the surface of Mars. You can check out the multiple posts that I did last year on the "7 minutes of terror" landing process here. For some new media, relive the landing with the crew in the following 4 minute video from NASA's Mars Science Laboratory (MSL) site. And yes, that is Mohawk guy (MSL systems engineer Bobak Ferdowsi) front and center.

A longer, in depth video celebration by NASA is below. It clocks in at about an hour.

An Awesome Poster on Social Media for Space

One of my space geek Facebook friends has recently taken it to the next level. Remco Timmerman put together a poster on social media and the space industry. If my tons of NASA posts haven't let you know already, social media has played a huge impact in furthering the public impact of space research.

Remco's poster,  "Social Media for Space",  was presented at the International Space University ISU alumni weekend poster session last weekend. According to the ISU Facebook page, "ISU provides an interdisciplinary education in the context of an intercultural and international environment to support the development of future leaders." They always have a great YouTube channel chock full of space stuff.

Check out the poster below. A higher res version is available for download here. 

 

Your Library May Have 3D Printing

Inside 3D Printing Expo

As I've blogged about before, 3D printers are awesome! They are a little expensive - Makerbot's 3D machines hover around $2000 - but you can print out small 3D trinkets and have a blast! The main store where you can see demos is the Makerbot store in NYC.  Luckily, some libraries are getting into the act and opening up their own 3D printing stations so that you can get in on the fun! 

According to the Washington Post :

Cleveland and D.C. are part of an expanding club of public libraries making 3-D printers available to patrons, often as part of a “maker lab” type environment. The Johnson County Public Library in the Kansas City suburbs debuted a “MakerSpace” in the spring with a MakerBot 3-D printer, iMacs, cameras and other equipment and software people might not normally be able to access at home.
The Westport Public Library in Connecticut launched a similar Maker Space with a 3-D printer this month after a successful “Maker Faire” showcasing the tech in the spring.   Ben Miller, director of the public library in Sauk City, Wis., called their acquisition of a 3-D printer in 2012 part of a larger move to “creation rather than consumption.”
