Phoenix Sky Harbor International Airport, a major transportation hub in Arizona, is set to undergo significant improvements with a new construction project at Terminal 3. According to AZ Family, the work is officially commencing this month on a project that will enhance the airport’s infrastructure, making it more accommodating for travelers.

Expansion at Sky Harbor

The upcoming expansion, which boasts a budget of $326 million, will introduce a new concourse on the north side of Terminal 3. This new addition is designed to increase the terminal’s capacity by adding six new passenger gates, bringing the total to 26 gates. The construction will encompass a vast 173,000 square feet, ultimately providing more flight options and enhanced facilities for travelers.

As reported by AZ Central, the expansion is much-needed, given that Terminal 3 is the oldest terminal at Sky Harbor. McCarthy Building Cos. Inc. has been entrusted with the construction, and they are committed to creating an exceptional experience for passengers. Thomas Assante, McCarthy’s senior project director, stated, “Every portion of the new Terminal 3 concourse will provide an exceptional experience for Sky Harbor passengers.” Notably, McCarthy has experience with airport projects, having recently completed a five-gate concourse at Mesa Gateway Airport, which opened in February 2024.

In addition to expanding gate capacity, the new Terminal 3 concourse plans to feature improvements beyond functionality. Travelers can look forward to new dining options, including three food and beverage spaces, as well as two retail spaces, alongside a passenger lounge. Greg Roybal, an airport spokesman, has confirmed these plans, emphasizing the project’s focus on improving the overall passenger experience.

The anticipated completion date for the new concourse is set for 2027. Once finished, this expansion will not only bolster the terminal’s capabilities but also enhance the amenities available to travelers. The airlines currently operating out of Terminal 3 include Delta, United, Frontier, and Alaska Airlines, among others.

As this construction project unfolds, we will keep readers updated with the latest developments and milestones. With these enhancements on the horizon, Sky Harbor Airport is poised to deliver an even better travel experience for passengers in the coming years. Stay tuned!

The 1970s prime-time television series “Emergency!” was an action-packed drama that followed the daily lives of courageous firefighters and paramedics in Los Angeles County. The show, which aired from 1972 to 1979, was praised not only for its gripping storylines and character development but also for its realistic portrayal of the emergency services industry. It provided a compelling look into the challenges and triumphs faced by first responders, highlighting their incredible dedication and heroism in the face of danger.

The Origin of Emergency!

The show was spun off from the original series “Adam-12,” which was also set in Los Angeles and followed the lives of two police officers. “Emergency!” took the same approach but shifted its focus to the lives of firefighters and paramedics. This innovative show was created by Robert A. Cinader and Jack Webb, the latter also known for producing “Adam-12” and “Dragnet.”

At the heart of “Emergency!” was its talented cast, led by Randolph Mantooth, who portrayed firefighter and paramedic John Gage. Mantooth’s charismatic performance was complemented by Kevin Tighe, who played his reliable partner Roy DeSoto. The ensemble cast also included Julie London, who breathed life into nurse Dixie McCall; Bobby Troup, who played the compassionate Dr. Joe Early; and Robert Fuller, who took on the role of the authoritative Dr. Kelly Brackett.

One of the show’s standout features was its commitment to authenticity. It was praised for its accurate portrayal of the emergency services industry, an effort bolstered by the involvement of real-life firefighters and paramedics serving as technical advisors. This attention to detail extended to the use of actual emergency vehicles and equipment, earning the show a loyal following of industry professionals and curious viewers alike.

“Emergency!” was known for its gripping action scenes, which often involved realistic special effects that depicted explosions, fires, and other dangerous situations. The show’s excitement wasn’t limited to physical dangers; it also tackled significant social issues of the time, such as drug abuse, mental health, and domestic violence. This made “Emergency!” a groundbreaking program that addressed topics other shows of the era often shied away from.

Despite its success, “Emergency!” was canceled in 1979 after seven impactful seasons. However, its legacy persisted. The show paved the way for subsequent action-packed dramas, such as “CHiPs” and “Miami Vice,” and it inspired a new generation of viewers to pursue careers in emergency services. The influence of “Emergency!” is also seen in modern medical dramas like “ER” and “Grey’s Anatomy,” which continue to blend high-stakes action with personal and social issues.

In retrospect, “Emergency!” not only entertained millions but also educated the public about the critical work of emergency responders and healthcare professionals, leaving a lasting impact on both television and real-world perceptions of these vital services.

Emergency! was a groundbreaking television series that meticulously followed the daily lives and challenges of firefighters and paramedics in Los Angeles County. The show was universally praised for its realistic portrayal of the emergency services industry, as well as for its thrilling and hair-raising action scenes. The cast was spearheaded by the talented Randolph Mantooth and Kevin Tighe, who delivered compelling performances that were both heartfelt and authentic. They were joined by a stellar supporting cast, including Julie London, Bobby Troup, and Robert Fuller, each bringing their unique charisma and depth to the show. Emergency! was initially spun off from the original series Adam-12, yet it carved out its own significant legacy, leaving an indelible mark on the television industry. More than just entertainment, the series brought public attention to the vital and courageous work of emergency responders, inspiring many to pursue careers in this essential field.

3D printing will help space pioneers make homes, tools and other stuff they need to colonize the Moon and Mars

Sven Bilén, Penn State

Throughout history, when pioneers set out across uncharted territory to settle in distant lands, they carried with them only the essentials: tools, seeds and clothing. Anything else would have to come from their new environment.

So they built shelter from local timber, rocks and sod; foraged for food and cultivated the soil beneath their feet; and fabricated tools from whatever they could scrounge up. It was difficult, but ultimately the successful ones made everything they needed to survive.

Something similar will take place when humanity leaves Earth for destinations such as the Moon and Mars – although astronauts will face even greater challenges than, for example, the Vikings did when they reached Greenland and Newfoundland. Not only will the astronauts have limited supplies and the need to live off the land; they won’t even be able to breathe the air.

Instead of axes and plows, however, today’s space pioneers will bring 3D printers. As an engineer and professor who is developing technologies to extend the human presence beyond Earth, I focus my work and research on these remarkable machines.

3D printers will make the tools, structures and habitats space pioneers need to survive in a hostile alien environment. They will enable long-term human presence on the Moon and Mars.

From hammers to habitats

On Earth, 3D printing can fabricate, layer by layer, thousands of things, from replacement hips to hammers to homes. These devices take raw materials, such as plastic, concrete or metal, and deposit it on a computerized programmed path to build a part. It’s often called “additive manufacturing,” because you keep adding material to make the part, rather than removing material, as is done in conventional machining.

Already, 3D printing in space is underway. On the International Space Station, astronauts use 3D printers to make tools and spare parts, such as ratchet wrenches, clamps and brackets. Depending on the part, printing time can take from around 30 minutes to several hours.

For now, the print materials are mostly hauled up from Earth. But NASA has also begun recycling some of those materials, such as waste plastic, to make new parts with the Refabricator, an advanced 3D printer installed in 2019.

Manufacturing in space

You may be wondering why space explorers can’t simply bring everything they need with them. After all, that’s how the International Space Station was built decades ago – by hauling tons of prefabricated components from Earth.

But that’s impractical for building habitats on other worlds. Launching materials into space is incredibly expensive. Right now, every pound launched aboard a rocket just to get to low Earth orbit costs thousands of dollars. To get materials to the Moon, NASA estimates the initial cost at around US$500,000 per pound.

Still, manufacturing things in space is a challenge. In the microgravity of space, or the reduced gravity of the Moon or Mars, materials behave differently than they do on Earth. Decrease or remove gravity, and materials cool and recrystallize differently. The Moon has one-sixth the gravity of Earth; Mars, about two-fifths. Engineers and scientists are working now to adapt 3D printers to function in these conditions.

Using otherworldly soil

On alien worlds, rather than plastic or metal, 3D printers will use the natural resources found in these environments. But finding the right raw materials is not easy. Habitats on the Moon and Mars must protect astronauts from the lack of air, extreme temperatures, micrometeorite impacts and radiation.

Regolith, the fine, dusty, sandlike particles that cover both the lunar and Martian surfaces, could be a primary ingredient to make these dwellings. Think of the regolith on both worlds as alien dirt – unlike Earth soil, it contains few nutrients, and as far as we know, no living organisms. But it might be a good raw material for 3D printing.

My colleagues began researching this possibility by first examining how regular cement behaves in space. I am now joining them to develop techniques for turning regolith into a printable material and to eventually test these on the Moon.

But obtaining otherworldly regolith is a problem. The regolith samples returned from the Moon during the Apollo missions in the 1960s and 70s are precious, difficult if not impossible to access for research purposes. So scientists are using regolith simulants to test ideas. Actual regolith may react quite differently than our simulants. We just don’t know.

What’s more, the regolith on the Moon is very different from what’s found on Mars. Martian regolith contains iron oxide –that’s what gives it a reddish color – but Moon regolith is mostly silicates; it’s much finer and more angular. Researchers will need to learn how to use both types in a 3D printer. https://www.youtube.com/embed/J1TWlNWHrsw?wmode=transparent&start=0 See models of otherworldly habitats.

Applications on Earth

NASA’s Moon-to-Mars Planetary Autonomous Construction Technology program, also known as MMPACT, is advancing the technology needed to print these habitats on alien worlds.

Among the approaches scientists are now exploring: a regolith-based concrete made in part from surface ice; melting the regolith at high temperatures, and then using molds to form it while it’s a liquid; and sintering, which means heating the regolith with concentrated sunlight, lasers or microwaves to fuse particles together without the need for binders.

Along those lines, my colleagues and I developed a Martian concrete we call MarsCrete, a material we used to 3D-print a small test structure for NASA in 2017.

Then, in May 2019, using another type of special concrete, we 3D-printed a one-third scale prototype Mars habitat that could support everything astronauts would need for long-term survival, including living, sleeping, research and food-production modules.

That prototype showcased the potential, and the challenges, of building housing on the red planet. But many of these technologies will benefit people on Earth too.

In the same way astronauts will make sustainable products from natural resources, homebuilders could make concretes from binders and aggregates found locally, and maybe even from recycled construction debris. Engineers are already adapting the techniques that could print Martian habitats to address housing shortages here at home. Indeed, 3D-printed homes are already on the market.

Meanwhile, the move continues toward establishing a human presence outside the Earth. Artemis III, now scheduled for liftoff in 2027, will be the first human Moon landing since 1972. A NASA trip to Mars could happen as early as 2035.

But wherever people go, and whenever they get there, I’m certain that 3D printers will be one of the primary tools to let human beings live off alien land.
