A Beginner’s Guide To Sustainable Aviation

Hello! I am an avid lover of the cosmos and all things too grand for our minds to grasp. I was wondering, honestly, how do you cope with the pressure of your jobs, or say the scale of what is on your shoulders? It's quite an impressive thing you do, and it just gets me curious as to how you deal with the expectations that come with this type of job? Like, when you go home at night and eat your dinner, go to bed, do you have to practice mindfulness? Thanks for answering these! Love you guys!!!

What’s Up - July 2018

What's Up for July?

Mars is closest to Earth since 2003!

July’s night skies feature Mars opposition on the 27th, when Mars, Earth, and the Sun all line up, and Mars’ closest approach to Earth since 2003 on the 31st. 

If you've been sky watching for 15 years or more, then you'll remember August 2003, when Mars approached closer to Earth than it had for thousands of years.

It was a very small percentage closer, but not so much that it was as big as the moon as some claimed.   

Astronomy clubs everywhere had long lines of people looking through their telescopes at the red planet, and they will again this month!

 If you are new to stargazing, this month and next will be a great time to check out Mars. 

Through a telescope, you should be able to make out some of the light and dark features, and sometimes polar ice. Right now, though, a huge Martian dust storm is obscuring many features, and less planetary detail is visible.

July 27th is Mars opposition, when Mars, Earth, and the Sun all line up, with Earth directly in the middle.

A few days later on July 31st is Mars' closest approach. That's when Mars and Earth are nearest to each other in their orbits around the Sun. Although there will be a lot of news focusing on one or the other of these two dates, Mars will be visible for many months.

By the end of July, Mars will be visible at sunset.

But the best time to view it is several hours after sunset, when Mars will appear higher in the sky.

Mars will still be visible after July and August, but each month it will shrink in apparent size as it travels farther from Earth in its orbit around the Sun.

On July 27th a total lunar eclipse will be visible in Australia, Asia, Africa, Europe and South America.

For those viewers, Mars will be right next to the eclipsing moon!

Next month will feature August's summer Perseids. It's not too soon to plan a dark sky getaway for the most popular meteor shower of the year!

Urban Growth of New Delhi

The capital of India, New Delhi, has been experiencing one of the fastest urban expansions in the world. Vast areas of croplands and grasslands are being turned into streets, buildings, and parking lots, attracting an unprecedented amount of new residents. By 2050, the United Nations projects India will add 400 million urban dwellers, which would be the largest urban migration in the world for the thirty-two year period.

These images show the growth in the city of New Delhi and its adjacent areas—a territory collectively known as Delhi—from December 5, 1989 to June 5, 2018. 

Most of the expansion in Delhi has occurred on the peripheries of New Delhi, as rural areas have become more urban. The geographic size of Delhi has almost doubled from 1991 to 2011, with the number of urban households doubling while the number of rural houses declined by half. Cities outside of Delhi—Bahadurgarh, Ghaziabad, Noida, Faridabad, and Gurugram—have also experienced urban growth over the past three decades, as shown in these images.

From Racing Suits to Robotic Gloves: How to Gear Up with NASA Technology

Did you know you are surrounded by NASA technology? From your apartment building to the doctor’s office, and even in your cellphone camera, there is more space in your life than you think!

In the latest edition of Spinoff, we are introducing dozens of new ways NASA technology could cross your path. Whether you need an extra “hand” on the production line or a weatherproof jacket, check out how to gear up with technology made for space.

Grip-Strengthening Glove

Robots are crucial to exploring space and other planets – they could even support astronauts and form the advance party for places humans have yet to reach. But the human machine is hard to replicate.

A collaboration with General Motors helped us build Robonaut 2 – and the design for this robot’s hands has been adapted into a robotic glove that helps manufacturing employees, such as automobile workers, reduce injuries and improve quality control.

The Swedish company Bioservo used the Robo-Glove technology to create the world’s first industrial-strength robotic glove for factory workers who perform repetitive manual tasks.

The Ironhand glove adds force to the user’s grip with artificial tendons and pressure sensors on the palm and the fingers.

The result? Reduced strain on the user’s own tendons and muscles, meaning fewer workplace stress injuries and better comfort for workers.

Temperature-Control Fabrics

Spacesuits need major insulation and temperature control to protect astronauts on extravehicular activities, aka spacewalks. To help solve this, we created a phase-change material with help from the Triangle Research and Development Corporation.

With funding from a NASA Small Business Innovation Research contract, Triangle incorporated the material into a fabric glove insert that could maintain a steady temperature by absorbing and releasing heat, ensuring it feels just right.

While the invention never made it to orbit, it did make it into the driver’s seat.

Outlast Technologies exclusively licensed the material from Triangle and has incorporated it into outdoor gear, bedding, and now – auto racing suits with help from Cambridge, England-based Walero.

Due to extreme temperatures in the cockpit, drivers in almost every major racing championship wear Walero for its cooling properties. Cristiana Oprea (pictured) wears it while driving for the European Rally Championship. Credit: Walero

The race undergarments, bonded with fire-retardant material for added protection, help drivers maintain a lower core temperature and heart rate, which means fewer mistakes and better lap times.

The suits have been sold to both amateur racers and professional NASCAR drivers.

Lightweight Rain Jackets

The superinsulating material that makes up space blankets is one of our most ubiquitous spinoffs. Found everywhere from inside the walls and roofs of buildings to cryogenic tanks and MRI machines, radiant barrier technology was first created to insulate spacesuits and spacecraft. And now this NASA spinoff can be found in weatherproof jackets as well.

Inspired by her passion to run following a series of surgeries to help correct a life-threatening injury, Hema Nambiar launched her Larchmont, New York, start-up company 13-One. To create her jacket, she worked with Advanced Flexible Materials Inc.’s brand Heatsheets. The brand was already marketing products like the space blankets traditionally distributed after races to prevent dangerous drops in temperature.

The 13-One jackets are designed to be warm and weatherproof, but their thin, reflective lining lets them also be lightweight and easily portable. Credit: Lourenso Ramautar, Out of New York Studio

The resulting line of jackets has a black exterior and a lining to reflect body heat. They weigh less than a pound, are wind- and water-resistant, and easily pack into a small, built-in pouch.

Solar System: Things to Know  This Week

This week, we’re looking at MAVEN’s exploration of Mars, the Orionid meteor showers, Mercury’s “great valley” and more.

1. Celebrating MAVEN

MAVEN, the Mars Atmospheric and Volatile Evolution, was the second mission selected for our Mars Scout program and the first to explore the planet’s upper atmosphere . It launched on November 18, 2013 and entered orbit around Mars on September 21, 2014. 

+ MAVEN Quick Facts

2. Jupiter Moon Dance

This time-lapse sequence of Hubble Space Telescope images shows Jupiter’s moon Europa as it moved across the planet’s face over the course of 19 minutes. Europa is at the bottom center on Jupiter's disk, the Great Red Spot to the left and Europa's shadow to its right. The video was created by combining six snapshots taken in ultraviolet light with Hubble's Wide Field Camera 3.

3. The Orionid Meteor Shower

Orionid shower peaks November 28. Look for the constellation Orion in the Southeast sky by 9 p.m. Using binoculars, look for the Orion Nebula. 

4. Comet Warming Up!! 

Comet 45P/Honda-Mrkos-Pajdu áková will brighten to expected stunning binocular visibility in mid to late December, but is near Venus on November 23rd.

+ Track the Comet

5. Mercury’s "Great Valley"

A newly discovered "great valley" in the southern hemisphere of Mercury provides more evidence that the planet closest to the sun is shrinking. Using stereo images from our MESSENGER spacecraft to create a high-resolution map, scientists have discovered that revealed the broad valley -- more than 620 miles (1,000 kilometers) long -- extending into the Rembrandt basin, one of the largest and youngest impact basins on Mercury. About 250 miles (400 kilometers) wide and 2 miles (3 kilometers) deep, Mercury's great valley is smaller than Mars' Valles Marineris, but larger than North America's Grand Canyon and wider and deeper than the Great Rift Valley in East Africa.

Could you theoretically time travel through a black hole or other object with such intense mass?

From Frozen Antarctica to the Cold Vacuum of Space

A new experiment that will collect tiny charged particles known as galactic cosmic rays will soon be added to the International Space Station. The Cosmic Ray Energetics And Mass for the International Space Station payload, nicknamed ISS-CREAM, will soon be installed in its new home on the Station’s Japanese Experiment Module Exposed Facility. ISS-CREAM will help scientists understand more about galactic cosmic rays and the processes that produce them.

Wait, what are cosmic rays?

Cosmic rays are pieces of atoms that move through space at nearly the speed of light. Galactic cosmic rays come from beyond our solar system. 

They provide us with direct samples of matter from distant places in our galaxy.

Why do these things go so fast?

Galactic cosmic rays have been sped up by extreme processes. When massive stars die, they explode as supernovas. The explosion’s blast wave expands into space along with a cloud of debris. 

Particles caught up in this blast wave can bounce around in it and slowly pick up speed. Eventually they move so fast they can escape the blast wave and race away as a cosmic ray.

Where can we catch cosmic rays?

Cosmic rays are constantly zipping through space at these super-fast speeds, running into whatever is in their path -- including Earth.  

But Earth’s atmosphere is a great shield, protecting us from 99.9 percent of the radiation coming from space, including most cosmic rays.  This is good news for life on Earth, but bad news for scientists studying cosmic rays.  

So… how do you deal with that?

Because Earth has such an effective shield against cosmic rays, the best place for scientists to study them is above our atmosphere -- in space.  Since the 1920s, scientists have tried to get their instruments as close to space as possible. One of the simplest ways to do this is to send these instruments up on balloons the size of football stadiums. These balloons are so large because they have to be able to both lift their own weight and that of their cargo, which can be heavier than a car. Scientific balloons fly to 120,000 feet or more above the ground -- that’s at least three times higher than you might fly in a commercial airplane!

Earlier versions of ISS-CREAM’s instruments were launched on these giant balloons from McMurdo Station in Antarctica seven times, starting in 2004, for a total of 191 days near the top of the atmosphere.  Each of these flights helped the team test their hardware and work towards sending a cutting-edge cosmic ray detector into space!  

How is going to space different than flying balloons?

Balloon flights allowed the team to collect a lot of cosmic rays, but even at 120,000 feet, a lot of the particles are still blocked. Scientists at the University of Maryland, College Park, who operate ISS-CREAM, expect to get about 10 times as much data from their new home on the International Space Station. 

That’s because it will be both above the atmosphere and fly far longer than is possible with a balloon. As you might imagine, there are large differences between flying something on a balloon and launching it into space. The science instruments and other systems had to be changed so ISS-CREAM could safely launch on a rocket and work in space.

What will ISS-CREAM do?

While on the space station, ISS-CREAM will collect millions of cosmic rays -- electrons, protons and atomic nuclei representing the elements found in the solar system. These results will help us understand why cosmic rays reach the wicked-fast speeds they do and, most important, what limits those speeds.

ISS-CREAM launches to the International Space Station aboard the latest SpaceX Dragon spacecraft, targeted to launch August 14. Want to learn more about ISS-CREAM and some of our scientific balloons? Check out our recent feature, NASA’s Scientific Balloon Program Reaches New Heights.

Space-Grown Crystals May Lead to More Efficient Drug Development

The International Space Station is a perfect environment for creating protein crystal structures for research.

In microgravity, protein molecules form more orderly, high-quality crystals. Studying these structures helps scientists understand their function and contributes to development of more effective treatments for diseases.

Experiments often need more than one try to generate ideal crystals, though. Researchers may have to return samples to Earth for analysis and then try again on a later mission on the space station.

Scientists are testing new methods of growing crystals that allow crew members to observe imperfections, make real-time adjustments, and try growing them again right away. This dramatically reduces the time and cost of conducting experiments aboard the space station and opens up the orbiting lab to more users. More efficient use of time and resources can produce research results in less time and lead to development of better drugs sooner.
