Pluto's Demotion

Happy Birthday Hubble Telescope! It’s been an amazing 25 years of breakthroughs in understanding our galaxy and how the universe works. For me, the most memorable discovery from your journey came when you detected Pluto’s two moons, and other objects in the Kuiper Belt found to have more mass than little Pluto.

That meant these moons could classify as planets, and as a result this discovery demoted Pluto to a “dwarf planet.”

That Pluto was removed it from the line up of planets I had memorized so carefully for my fifth grade science class, shocked me. Hubble’s images are so clear and provide scientists a look at objects we had never seen before in deep space, leading to radical changes and new theories about the makeup of our universe. Hubble quite literally opened my eyes to the idea there was something beyond Pluto - our solar system is a big concept to grasp but what lies beyond became something more than just what I had imagined when I watched Star Trek or Star Wars.

For the first time I understood the universe is not a static thing. Its planets, exoplanets, comets, galaxies, and more are changing all the time. It fills me with excitement and wonder as we look to solve the mysteries behind how and why that happens. Thanks for the inspiration Hubble! 

Look for more posts from scientists, astrophysicists, and space experts on their Hubble moments.

3D Printed Shelby Cobra Is A Stunner

Imagine a world where you could order every detail you ever wanted from a car online and have it 3D printed to your specifications. Or, where once very rare cars are replicated via 3D printing for a new generation.

The 3D printed car is here. The first model, the Strati was a little rough around the edges, but it didn’t take long for the developers to raise the bar and re-create a 1965 Shelby Cobra 427 in honor of its 50th anniversary this January. The printed Cobra was definitely finished to be a stunner.

The car is a collaboration of many companies. The 3D chassis and electric motor came courtesy of the US Department of Energy's Oak Ridge National Laboratory (ORNL). They used their Big Area Additive Manufacturing printer, which can print single pieces in sizes greater than one cubic meter – and in this case they used a composite that included 20 percent carbon fiber.

The 3D-Printed Cobra took just six weeks to complete, though the printing itself only took about 24 hours. The signature Cobra sleek blue and white finish was the work of Knoxville, Tennessee-based company Tru-Design that specializes in carbon fiber and fiberglass.

 

With such a gorgeous and speedy end result it’s easy to see what ORNL is trying to innovate. The idea is that with 3D printing the manufacturing process can be done on a large and rapid scale. The 3D-Cobra is proof that something as large as a car, needing both style and durability can be created with 3D printers and may one day change the automotive industry and perhaps have an impact on the environment.

The team that worked on the car has dubbed it a “laboratory on wheels.”

As the ORNL team works to take the process of 3D printed cars to the next level, the shift could change many things – concept cars could more easily come to fruition. Rare models could be replicated. Even better, your daily ride could be customized to you. It’s an interesting future to contemplate.

If you live or are visiting in the Washington DC area now, you can see the 3D Shelby in the lobby of the Department of Energy. You can follow its progress on Twitter via #3DPrintedCar.

Unique Problem Solvers

Sometimes HOW IT’S MADE covers some pretty unique items. They range from the often every day item that makes our life easier, to the out of this world items that fascinate us. The of items all do one thing – solve some of life’s problems.

Humans have always faced problems, but from the start we figured out ways around them. In the beginning, our most immediate problems were finding food and shelter, and thus manufacturing began. Creating flint arrows and stone axes were the solution, and clusters of humanity began the refining the quality and speed with which the items were made.

As humankind has progressed, so have the incredible challenges and needs we’ve faced. How do we build villages and communities? How do we create more food to feed the population? How do we create items that signify value of things we possess? The answer is simple – look for the basic tools and resources around you and then build upon them to make them fit the ever-changing needs of society. The inspiration to create has always been there, but in the early days the scale of mass manufacturing was simply not possible.

With the dawn of the Industrial Revolution in the late 1700’s it slowly became possible to move from creating bespoke items that met our needs to producing on a grand scale. The invention of the steam engine and eventually harnessing electricity allowed for us to create massive factories and to move the products and resources around in a way that changed our lives forever. The bigger problem of how do you actually make the things that make our lives better was finally able to go wide.

If you’ve grown up in the 20th century you have the confidence of having most products that solve your problems at your fingertips. Hair dryers, vacuum cleaners, cell phones, ATMs, Wi-Fi – they are all things we take for granted and yet we shouldn’t forget that these great ideas needed to be perfected and executed to make it into our homes. We’ve come a long way from the manufacturing technology of the 1700’s; we have robotic production lines, computers, advanced equipment, easier access to resources, and advanced transportation that are entirely focused on the logistics of making things and making them for the masses.

In this world we have the luxury of looking a little problem like “How can I avoiding hauling my heavy luggage through the airport?” and solutions like rolling luggage is invented and now produced on a mass level. We have the ability to take problems like how to create energy when our primary sources go down? Stand-by generators are now a given in places like hospitals where loss of electricity could literally be life or death for patients. And there are the problems we never thought we’d face, like “How do you write in zero gravity where the ink can’t flow? Even in 1920, the idea of going to space, much less living in it was a fantasy and yet humans have advanced and adapted to make their ideas happen, and on a big scale.

Around here at Science Channel we love seeing behind that curtain of how items are made, parts upon parts, pieced together to make something we take for granted or can’t live without. We can look back to the foundation of how items are made into the future as makers, manufacturers and big ideas keep creating amazing items that take us to the next level.

Who among us wouldn’t want to know how a bionic arm is made? Or space planes? Or 3-D printed cars? These lists of challenges we have to overcome will never end, nor will the process and logistics of making items. We can’t wait to see technology advance and future play out in HOW IT'S MADE!

HOW IT'S MADE airs Thursdays, 9p.

Finding Alien Life by 2025

Watereventfeature20150407_mainNASA chief scientist Ellen Stofan thinks so. "I think  within a decade, we're going to have strong indications of life beyond Earth, and I think we're going to have definitive evidence within 20 to 30 years," she said Tuesday during a panel event on water in the universe.

That’s a thought provoking statement! Why would she make this announcement during a panel on water? NASA has long been searching for the evidence of water in the universe and is announcing new missions to discover and understand how water is distributed in the universe. With this announcement, it is no surprise the topic turns to finding life beyond Earth. The discovery of water on other planets and exoplanets is one strong indicator that alien life could be found there, as in many cases it is a building block for known life forms.

Stofan isn’t the only one who believes the pace at which we are unlocking new understanding about the universe will reveal alien life.

"It's definitely not an if, it's a when," said Jeffery Newmark, NASA's interim director of heliophysics.

Information coming back from NASA missions has shown the atmospheres and interiors of Jupiter, Saturn, Uranus and Neptune are thought to contain enormous quantities of water. Even the five icy moons of Jupiter and Saturn show evidence of there may be oceans beneath their icy surfaces. As we probe further in the universe we are finding more evidence of the water and the elements of water, hydrogen and oxygen everywhere and in many forms.

Scientists are quick to point out that finding alien life doesn’t necessarily mean meeting little green men, or the kind of semi-human sentient beings we think of from Star Trek or Star Wars. The likelihood is our first encounter may be microbes, perhaps similar to those that evolve and change on our own Earth over time.

More: Will Aliens Have Bodies?

As much as the headline of yesterday’s panel focused on water as a barometer of finding alien life, the study of water and how it behaves in the universe is also helpful in understanding how our own solar system evolved and why some planets have water and why some who may have had water have dried up.

By being able to observe other planetary systems as they form helps paint the picture of how our own solar system developed, and water is a big part of that story. NASA reports the Spitzer Space Telescope has observed signs of a hail of water-rich comets raining down on a young solar system, much like the kind of bombardment planets in our solar system would have endured in their youth. This could very well be how our own Earth became populated with water.

Many of NASA’s existing missions like Kepler and its successor K2 are laying the groundwork now. NASA is also launching the TESS mission will search nearby, bright stars in the solar neighborhood for Earth sized exoplanets in conjunction with the launch of the James Webb Space Telescope (JWST).

More: The Quest For Life: Water

Watching another distant solar system that could be like ours is a powerful concept to wrap one’s head around. The oceans we swim and sail in, the rivers we see, and the water we drink may well have come from a cosmic event that is just in the offing for other planets in other solar systems.

With that in mind, when we look to the skies, and consider the idea of alien life forms being found it’s hard not to wonder if there are other life forms on distant planets who are going through the process of developing into life forms we might recognize.

With its targeted missions to understand deeper space better in the pipeline, NASA is in the unique position to be able to make that bold prediction that we may find some form of life within the next 20 – 30 years.

 All we can say is wow!  For more of where water has been discovered, explore NASA's infographic below.

Astronaut Leland Melvin On The #YearInSpace

We are fortunate here at the Science Channel to have Astronaut Leland Melvin as a friend and adviser. As we contemplated the enormity of Expedition #43 and the #YearInSpace mission we turned to Leland to give us a reality check.

What does it feel like to be launched into space? As we watched the crew in the capsule during the various stages of launch they had nothing but the "RIght Stuff." Calm, composed, and punching their checklists. That doesn't mean they aren't feeling and noticing every change as the stages fall away, they get lighter and faster and feel those g's.

Leland tells us what it feels like to launch into space and what it's like to live and work in the ISS. Did you know that the ISS is about the size of a 747? It's that kind of perspective only an Astronaut would have and Leland shares that fact - and many more insights on the incredible opportunity of having traveled in space. Be sure to watch all three videos to get the scoop.

We are thrilled to share and promote his passion for space, exploration, curiosity, as humankind taking steps together to explore deeper into space.

What Will Happen In The #YearInSpace?

Astronauts have been noting the effects of space on the human body since the very first launch. We've come a long way from the first orbits to the six month stays. We now know there are changes that happen over time - things like bone density loss, vision changes and more. So if that happens in a six month period, what will happen if we plan to colonize and explore deep space - missions that will take years to complete?

The #YearInSpace mission is going to study the Astronauts closely to see what will happen. Here's a video from #NASA featuring NASA Commentator Pat Ryan interviewing Dr. John Charles of NASA’s Human Research Program about just what is planned for their extended stay.

The Year in Space

Why all the fuss about the launch tomorrow from the Baikour Cosmodrome in Kazakhstan? Expedition 43, also being referred to as the #YearInSpace is a giant step forward for humans one day colonizing other planets and exploring deep space.

This is the first time astronauts will have spent over a year in space and in addition to their regular duties on the ISS, they will be closely studying the effect prolonged space travel has on the human body. The mission will test the physical and psychological health and changes to the crew, and presents a unique opportunity for scientists and flight surgeons since Astronaut Scott Kelly's identical twin Mark will be part of the mission here on Earth. Since they possess the same DNA, seeing changes between Scott and Mark will provide a fascinating and exacting insight as to how space travel changes the body.

 

And, since we here at Science Channel believe in questioning everything, we wonder if perhaps Mark Kelly, the Earth-bound twin will experience any changes himself since twins have reported sharing the same changes and experiences across long distances?

The International Space Station is in orbit some 240 miles above the Earth, and a year is a long time to participate in this exploration of human endurance. By participating in this crucial mission, these bold adventurers will truly be helping humankind make its first steps towards a greater unknown by testing the limits of what we now know about long term living and exploring space.
