Astronauts aboard the International Space Station have dodged a cosmic bullet ... literally.

A small piece of space junk or naturally occurring celestial debris created the tiny hole in one of the space station's wing-like solar arrays at some point in the outpost's 14-year history in orbit. Canadian Space Agency astronaut Chris Hadfield spotted the puncture and posted a photo of it on Twitter on Monday.

"Bullet hole a small stone from the universe went through our solar array," Hadfield wrote, suspecting the hole was caused by a tiny space rock called a micrometeoroid. "Glad it missed the hull." [Chris Hadfield's Video Guide to Life in Space]

NASA experts estimate that millions of micrometeorites and bits of man-made debris orbit the Earth in the range of operational satellites and the space station. These shards of satellites, rockets and rocky debris are traveling at an average speed of 22,000 mph (35,406 km/h). The space station, for comparison, orbits the Earth at a speed of about 17,500 mph (28,164 km/h).

"The 'bullet' that created the hole in the solar array was probably due to a 1 mm to 2 mm diameter MMOD (micrometeoroids and orbital debris) impact, assuming the hole was on the order of 0.25 inches in diameter," William Jeffs, a NASA spokesman, told Space.com in an email. "A 2 mm size MMOD particle is expected to hit somewhere on (the International Space Station) every 6 months or so."

If the piece of space debriswere to collide with the hull, the space station's shielding would probably protect the crew from being adversely impacted, Jeffs added.

NASA scientists regularly track pieces of space debris larger than 4 inches (10 centimeters) across in order to avoid potentially destructive collisions. Radar systems track these larger pieces of space junk to alert space station operators and satellite controllers to any threats.

During his evening ritual of sharing images taken from the International Space Station, Commander Chris Hadfield posted this gem: a gorgeous night-time view of the southeastern United States, with the Moon hovering over Earths limb and the terminator separating night from day. Dawn is just beginning to break to the east, as the ISS flies overhead.

This image reflects the wistful feelings Hadfield is having as his time in space in coming to a close. He and his two crewmates Tom Marshburn and Roman Romanenko will head back to Earth on May 13. During a recent linkup with students, Hadfield said he is becoming wistful as he does tasks aboard the ISS, realizing he is doing some for the last time. He is trying to spending as much of his free time gazing out the window at Earth because of the magnificent rarity of it and my desire to absorb as much of it as I possibly can.

Hadfield said his emotions go between feelings of great responsibility and great honor to have been asked to command the space station, and he wants to do it right, making the most of his experience and communicating to as many people as possible on Earth.

You do feel the responsibility of it to try and do it right, to try and have one perfect day on the station where I dont make even one little mistake in any of the procedures, and I havent done it yet, Hadfield admitted. Ive been here 130 days and I have yet to have day where I havent made at least one little small mistake.

Some aspects of returning home are enticing: seeing family and friends, and eating things that arent dehydrated and come in a vacuum packed bag.

Im looking forward to fresh food and the crunch and the snap of food of all different varieties and the smell of rich coffee and the smell of fresh bread baking that type of thing, a more full assault of the senses when I get home, Hadfield said.

"Collision with these particles can cause serious damage or catastrophic failure to spacecraft or satellites and is a life-threatening risk to astronauts conducting extra-vehicular activities in space," NASA officials from the agency's Johnson Space Center wrote on the White Sands Test Facility website.

The International Space Station can maneuver out of the way of larger meteoroids and bits of debris if their orbits are tracked well ahead of time.

Particles smaller than 4 inches (10 cm) and larger than 0.4 inches (1 cm) pose a unique problem for tracking efforts, however.

Soon we may be able to get student experiments manifest onto station through the CASIS lab. In October, William Gerstenmeir, associate administrator for Human Exploration and Operations, the CASIS lab director, Jim Royston, and even the president of SpaceX, Gwynne Shotwell will be coming to Las Cruces to talk about this facility. It is the beginning for taxpayers to participate in a great leap for human knowledge, started in 1984. In his State of the Union address, President Reagan stated, "A space station will permit quantum leaps in our research in science, communications NASA will invite other countries to participate so we can strengthen peace,

The shuttle and the Russian Soyuz, both government developed and operated launch vehicles, ferried the construction materials and "construction worker" astronauts to space to build the ISS. In 2012, with significant private investment after nearly a billion-dollar NASA investment, the privately built Falcon 9 docked its Dragon capsule with the ISS. SpaceX is the first private American launch company to dock with ISS. President Reagan predicted this day would come. And hopefully, we will manifest a New Mexico experiment on ISS.

President Reagan, and all succeeding presidents, supported the public-private partnership for the future of space faring nations. The free world will work in space together. We are still on course. The importance of maturity is that we learn as we age. Visionaries who are builders and partners look to benefit mankind. They understand it takes partners and peace to build. We can't grow and take giant leaps in knowledge if we are at war.

The space station was a post Cold War science and engineering super project. It was a political decision. It was made, in part, to keep the Russian scientists occupied on something as prestigious as being the major builder, along with the United States, in a project of stunning magnitude. Big enough even for the Russians to agree, cooperating was better than competing with the winners of the Cold War. How did we beat the Russians? Not militarily, we beat them with capitalism. The consumer beat the Kremlin. And here is where we, the American public, the mighty consumer have a role to play - we have great power.

Did anyone notice how quickly Congress leapt into action after the air-traffic controller furloughs started on Monday. The FAA says it can shave off $200 million through the furloughs of 47,000 employees, including about 13,000 air-traffic controllers, and that it has few other places where savings can be achieved. The American consumer, the taxpayers, got furious with Congress and it took five working days to fix the problem with the air traffic controller furloughs.

I'd like the consumer - doing business as the American taxpayer, to look at building our nation through positive action. The ISS will create giant leaps in human knowledge. In 2005, Congress designated the U.S. portion of the ISS as a national laboratory. It is finally becoming possible for our students and faculty to use this laboratory facility called the Center for Science in Space - CASIS. We will take the first steps this week in discussing this option with the Las Cruces Public School leadership. Keep looking up.

TERRAHEART Project Once again Includes Winning Art in Launch to Space

COLORADO SPRINGS, Colo. (April 30, 2013) -- Digital images of artwork honored by the Space Foundation International Student Art Contest will travel to space this summer and take up residence aboard the International Space Station (ISS) as part of the Japanese program called TERRAHEART, which sends student art, poetry and writings into space. This is the second time TERRAHEART has invited the Space Foundation to send student art and the first time the art will travel to the ISS aboard a Japanese rocket. A DVD of the images will be launched by HIIB this summer from JAXA Tanegashima Space Center, in the southern part of Japan.

The Space Foundation 2013 International Student Art Contest invited students in pre-kindergarten through 12th grade from around the world to submit original artwork depicting the theme If I were Going ... , resulting in more than 4,700 entries representing 45 countries, including 38 U.S. states and territories - the largest response since the contest began three years ago. Thirty-six works of art were recognized and displayed at the recent 29th National Space Symposium, held April 8-11 in Colorado Springs.

About TERRAHEART

The TERRAHEART project works with teachers in schools and other educational institutions in Japan to stimulate discussion about the future in the context of space. Through classroom activities and interconnected websites, the project explores:

* What kinds of support do we need to help children develop and nurture their powers to live as good inhabitants of the Earth?

* For each stage of their development, how can we strengthen the links between children, their inner selves, other human beings and nature - the Earth or the universe? The connection between the Space Foundation and TERRAHEART was made by the Japan Space Forum (JSF), which coordinates an alliance of industry, government and academia for the development of Japan's aerospace industry. Operating under policies established by the Japanese government, JSF supports research proposals and implements programs to educate and enlighten the public about the aerospace industry as well as provide for the exchange and development of human resources. Space Foundation International Student Art Contest Winners Represent 12 Countries The winners of the Space Foundation International Student Art Contest, whose artwork will travel to space (organized by state and school), are:

Space Foundation Student Art Headed for the International Space Station

NASA officials are confident lithium-ion batteries due to launch to the International Space Station in 2016 will not overheat like the batteries that grounded the Boeing 787 Dreamliner earlier this year.

File photo of the International Space Station. Credit: NASA The space station's existing nickel-hydrogen are up for replacement in a few years, and NASA managers selected more efficient lithium-ion batteries for the job.

Pratt & Whitney Rocketdyne - NASA's space station battery contractor - tapped GS Yuasa Lithium Power Inc., a U.S.-based subsidiary of GS Yuasa Corp. of Japan, to supply the cells for the space station's next-generation lithium-ion batteries.

GS Yuasa is also the supplier for batteries used on the Boeing 787 airplane, which was grounded in January after batteries aboard two of the jumbo jets smoldered and caught fire.

No crew members or passengers were injured in the incidents, but one firefighter received minor injuries while responding to the fire on a Japan Airlines 787 on the ground in Boston.

Kirk Shireman, NASA's deputy space station program manager, said earlier this month that the space station batteries should not be affected by the problem.

Engineers working on the Dreamliner have devised ways Boeing says will prevent similar problems in the future, but investigators have not found the root cause of the battery overheating. The suspect batteries provide electricity to the Dreamliner's auxiliary power unit. The Dreamliner batteries include eight cells arranged in a four-by-two matrix.

Credit: NTSB Officials attributed the battery failures to "thermal runaway," where overheating in one cell can lead to the meltdown of other cells within a battery - a chain reaction which could ultimately spread beyond the battery and into other airplane systems if not extinguished.

Engineers at Boeing, GS Yuasa and Thales, one of the 787's electrical system subcontractors, redesigned the batteries to prevent overheating in one cell from cascading into other sections of the battery. The contractors beefed up the battery's casing to contain a fire.

The Dreamliner returned to commercial service Saturday with an Ethiopian Airlines flight, two days after the Federal Aviation Administration approved Boeing's battery fix. Other carriers will resume Dreamliner flights over the next couple of months as national regulatory agencies grant approvals following the installation of redesigned batteries.

NASA says space station's batteries safer than 787's

Watch the unveiling of Canada's new $5 bill, featuring space station commander Chris Hadfield.

By Alan Boyle, Science Editor, NBC News

Canada's new printed-polymer $5 bill has received the country's highest sendoff, altitude-wise, from International Space Station commander Chris Hadfield. Tuesday's currency-unveiling ceremony in space was just the latest in a series of achievements that have drawn attention to Canada's best-known spaceflier.

Hadfield already has made his mark as a photographer, a musician and composer, and an explainer of outer-space phenomena ranging fromcryingto vomiting in zero-G. There's a reason why the Bank of Canada turned to him to introduce one of the last currency notes to be converted to counterfeit-resistant polymer: One side of the $5 bill celebrates Canada's contributions to space exploration, including the space station's Canadarm2 and DEXTRE robot.

"I just want to tell you how proud I am to be able to see Canada's achievements in space highlighted on our money," Hadfield told Canadian officials via a space-to-Earth video link. Hadfield said the pictures played to Canada's strength in space robotics.

As Hadfield spoke, he plucked a bill from the wall of the station's Destiny laboratory and set it spinning in zero gravity in front of the camera. The other side of the bill has a less spacey theme: It features a portrait of Sir Wilfrid Laurier, who was Canada's prime minister from 1896 to 1911.

Bank of Canada spokeswoman Julie Girard said the outer-space ceremony was "quite a few months in the making." The polymer note was flown up to the space station with Hadfield back in December, and held in reserve for Tuesday's ceremony. "We wanted to be the first to unveil a bank note in space," she told NBC News.

Bank of Canada

This rendition of the Canadian $5 bill shows Canadarm2 and DEXTRE in more detail. The bank note is to be issued in November.

Canada's new $10 note, which commemorates the country's rail system, was unveiled at the same time in Ottawa. The $5 and $10 bills will complete Canada's conversion to polymer-based currency, tricked up with transparent areas and hologram markings to make them harder to counterfeit. The Bank of Canada says these notes should last two to three times longer than the country's cotton-based paper bank notes and when they wear out, they can be traded in and recycled.
