The International Space Station is the third brightest object in the sky (after the sun and moon) – it can be seen without a telescope by the naked eye.
The ISS is even visible when spotted over a city and flies over about 90 percent of the Earth’s population.

How do you know when to look up?
NASA is now offering a Spot the Station service. This provides a list of upcoming opportunities to spot the ISS from thousands of world locations. You can also sign up to receive an email or a message on your cell phone when it’s overhead. You will only receive alerts during prime viewing opportune times, like only when the station is high enough over the horizon and in view long enough. NASA believes most will receive alerts a few times a week to a few times a month.
The ISS looks like a fast moving airplane but is much higher and travels thousands of miles an hour faster. It orbits the Earth every 90 minutes.
The station is about the size of a football field and has more livable space than a six-bedroom house, including two bathrooms, a gym and a 360-degree bay window.

Here are some facts about the ISS, courtesy of NASA -
- The International Space Station marked its 10th anniversary of continuous human occupation on Nov. 2, 2010. Since Expedition 1, which launched Oct. 31, 2000, and docked Nov. 2, the space station has been visited by 204 individuals.
- At the time of the anniversary, the station’s odometer read more than 1.5 billion statute miles (the equivalent of eight round trips to the Sun), over the course of 57,361 orbits around the Earth.
- A total of 174 spacewalks have been conducted in support of space station assembly totaling almost 1,100 hours, or nearly 46 days.
The International Space Station is not only an orbiting laboratory, but also a space port for a variety of international spacecraft. As of June 2013, there have been:
- 89 Russian launches
- 37 Space Shuttle launches
- 1 test flight and 2 operational flights by SpaceX’s Dragon
- 3 Japanese HTVs
- 3 European ATVs
Move over ‘selfie,’ there’s a new word of the year in town.
Merriam-Webster, America’s leading dictionary publisher, announced its Top 10 Word of the Year on December 3rd. Their choices weren’t based on the new, hip buzz words, but instead by the lookups on the online dictionary. The words that made their list had the biggest increase in lookups over last year.
The words that increased in lookups were not new or headline-worthy, but instead were “words behind the stories in this year’s news.”
‘Science’ saw an increase of 176 percent in lookups in 2013.
Peter Sokolowski, Editor-at-Large at Merriam-Webster believes ‘science’ tops the list because of a wide variety of topics and discussions that came about this year, from climate change to educational policy.
“We saw heated debates about ‘phony’ science, or whether science held all the answers. It’s a topic that has great significance for us. And it fascinates us–enough so that it saw a 176% increase in lookups this year over last, and stayed a top lookup throughout the year,” Sokolowski explained.
We decided to have some fun at the recent National Science Teacher Association’s conference in Denver. Some crazy science teachers took #ScienceSelfies with Steve. Are you a science teacher, science student or science fan? Take your own #ScienceSelfie and share it with us on Twitter using the hashtag. We can’t wait to see what you come up with.
Merriam-Webster’s Word of the Year for 2013:
Fort Lauderdale, Florida sixth grader Peyton Robertson may revolutionize how we protect ourselves and property from flooding.
Earlier this month, he won the Discovery Education 3M Young Scientist Challenge for his sandless sandbag. The Young Scientist Challenge is sponsored by 3M and the Discovery Channel Education and is open to students in grades 5 – 8. The 2014 challenge opens in late December. Student scientists can win cash prizes and trips.

Robertson, who wants to be an inventor when he grows up, has invented a sandbag that doesn’t use sand to stop flooding. His bag is “sandless” and contains a much lighter polymer. Sandbags weigh about 40 pounds each, but the sandless sandbag only weighs only a few pounds.
The sandless bag is filled with a mixture of an “ultra-fluid” polymer and salt. When the bag gets wet, the polymer absorbs water and expands, keeping water from seeping through the cracks between bags. This bag is heavy when expanded and won’t float away either.

The polymer looks very similar to our Water Gel or Insta-Snow, or the polymer found in a baby diaper. Insta-Snow starts out as a fine white powder, but when water is added, the powder absorbs it and quickly expands.
Robertson says he came up with the idea after he and his family hid in a closet during Hurricane Wilma in 2005. It was the third hurricane in the 2005 season to reach Category 5 status. Wilma was also the most intense tropical cyclone ever recorded in the Atlantic and was responsible for 62 deaths. His neighborhood was devastated by the damage, so Robertson set off to find a way to keep the water out.

The Colorado Front Range is still reeling after a major storm dumped more precipitation on areas in 24 to 48 hours than they receive in an entire year. The result was 20-foot walls of water rushing down the sides of mountains, rivers coming over their banks, roads and bridges washed away and houses flooded. Hundreds of roads and bridges washed away across the Front Range. Some places, like the town of Lyons, became islands completely surrounded by water.

The flooding has effected 17 Colorado counties with the most devastating in Boulder and Larimer counties. Parts of Jefferson County around Golden and Evergreen and Arapahoe County in Aurora are also affected.
Renault is the first car manufacturer to sell a zero-emission vehicle. They have an entire line of electric cars to suit every need and motorhead.
Their newest and smallest car, the Twizy Electric Car, uses the same tires as Renault’s Formula 2.0 car and a Forumla One-styled steering wheel. The car also has LED headlights, two electric motors, and a screen with real-time vehicle data. The Twizy is a double–person commuter car that looks like something out of the movie TRON, or maybe Mario Cart. Add a little plastic steering wheel and Mario is ready to race!
The Twizy also incorporates an intelligent alternator. This high-tech device captures the kinetic energy used while braking and uses it to boost power, instead of just losing it as heat.
The driver and passenger sit tantum-style. One style will top out at about 45 kph and can be driven without a license. The faster version can go about 80kph and requires a license. This is a car that is open-air but doesn’t require a helmet like a motorcycle.
Renault cars contain at least 7% recycled plastic and are 95% recyclable themselves. The electric cars are quiet while idling (the engine turns off) and then start right up when the light turns green.
The downside? The cars are only available in Europe but will hopefully travel across the pond someday to buzz along America’s highways.
