“It’s Summer Camp for Aviation Geeks”: NASA Returns to EAA AirVenture Oshkosh

As a child fascinated with aviation, Michael Jorgensen, Public Affairs Specialist for the Electrified Powertrain Flight Demonstration project, attended EAA AirVenture Oshkosh (“Oshkosh” for short) multiple times. Now, he represents us there, sharing what we’ve been working on. Read on to see what going to Oshkosh is like as Michael takes us on a tour—and join us next time!

MICHAEL:

Every year, Wittman Regional Airport in the town of Oshkosh, Wisconsin, swells from 67,000 to 600,000 people, becoming a hotspot for aviation in the United States. The Experimental Aircraft Association (EAA) began AirVenture in 1953 and is a ‘Must Do’ for any aviation geek.

My story with EAA AirVenture began in the late 1990s. As a fan of everything aviation, and having grown up near Chicago, Oshkosh was always on my radar – and I attended several times while I was growing up.

Coming back to the airport grounds this week, all my childhood memories came flooding back: the noises, the planes, the smells, and the pure excitement. As a kid, I could only dream of working for NASA, never imagining it would come true almost 25 years later.

When driving in, you first see a lot of air traffic – ranging from hang gliders, to old warbirds, to stunt planes, to the newest military jets rumbling skyward. During the last full week in July, the airport control tower becomes the busiest one in the world, coordinating approximately 116 takeoffs/landings per hour throughout each day – almost 2 every minute! Last year saw more than 10,000 aircraft arrive at the airport. The excitement grows as you pull off the highway and are greeted by rows and rows of general aviation aircraft as far as the eye can see.

The constant propeller buzz in the background and crackling of fighter jets overhead is noticeable as you walk through the airport grounds. What makes this sight even more unique is camping tents under the wings of each aircraft, stretching along the entire grounds of the airport. AirVenture truly is a summer camp for #AvGeeks.

The main tarmac at the airport is converted into Boeing Plaza, the central display area featuring the biggest and most exciting aircraft: C-17 Globetrotter III, SR-71 Blackbird, F-117 Nighthawk, DC-3, and many, many more. One year, I even got to see the Concorde fly into and out of this teeny regional airport in the middle of Wisconsin.

There are countless opportunities to interact with the pilots and other aviation enthusiasts including sitting in cockpits, checking out the interiors and exteriors of various airplanes, and chances to fly in vintage aircraft including an original 1929 Ford Trimotor and a B-17 Flying Fortress from 1945. And, of course, no matter my age, I posed with anything and everything I found interesting, including a T-38 Talon stationed in front of the NASA pavilion and the inside of an ecoDemonstrator.

This year’s theme for the NASA pavilion was “Faces of Flight”. Throughout the week, we had meet-and-greets with leaders, researchers, engineers, and even an astronaut or two, hands-on educational experiences for guests of all ages, giveaways, and models of our aircraft, spacecraft, and more, including a model of the Ingenuity Mars Helicopter and the Space Launch System rocket.

Aside from the events in the NASA pavilion, we participated in a number of panels like Women@NASA, where women leaders from the Aeronautics Research Mission Directorate talked about NASA’s aviation research portfolio, activities taking places at NASA centers, and their personal experiences as leaders.

If you’re interested in the future of aviation—supersonic flight, advanced air mobility, and so much more—come see us at Oshkosh!

How did your perspective on Earth & humanity change from space?

How has being in space changed your perspective of life on Earth?

Farewell to the Van Allen Probes

After seven years of studying the radiation around Earth, the Van Allen Probes spacecraft have retired.

Originally slated for a two-year mission, these two spacecraft studied Earth's radiation belts — giant, donut-shaped clouds of particles surrounding Earth — for nearly seven years. The mission team used the last of their propellant this year to place the spacecraft into a lower orbit that will eventually decay, allowing the Van Allen Probes to re-enter and burn up in Earth's atmosphere.

Earth's radiation belts exist because energized charged particles from the Sun and other sources in space become trapped in our planet's huge magnetic field, creating vast regions around Earth that teem with radiation. This is one of the harshest environments in space — and the Van Allen Probes survived more than three times longer than planned orbiting through this intense region.

The shape, size and intensity of the radiation belts change, meaning that satellites — like those used for telecommunications and GPS — can be bombarded with a sudden influx of radiation. The Van Allen Probes shed new light on what invisible forces drive these changes — like waves of charged particles and electromagnetic fields driven by the Sun, called space weather. 

Here are a few scientific highlights from the Van Allen Probes — from the early days of the mission to earlier this year:

The Van Allen belts were first discovered in 1958, and for decades, scientists thought there were only two concentric belts. But, days after the Van Allen Probes launched, scientists discovered that during times of intense solar activity, a third belt can form.

The belts are composed of charged particles and electromagnetic fields and can be energized by different types of plasma waves. One type, called electrostatic double layers, appear as short blips of enhanced electric field. During one observing period, Probe B saw 7,000 such blips repeatedly pass over the spacecraft in a single minute!

During big space weather storms, which are ultimately caused by activity on the Sun, ions — electrically charged atoms or molecules — can be pushed deep into Earth’s magnetosphere. These particles carry electromagnetic currents that circle around the planet and can dramatically distort Earth’s magnetic field.

Across space, fluctuating electric and magnetic fields can create what are known as plasma waves. These waves intensify during space weather storms and can accelerate particles to incredible speeds. The Van Allen Probes found that one type of plasma wave known as hiss can contribute greatly to the loss of electrons from the belts.

The Van Allen belts are composed of electrons and ions with a range of energies. In 2015, research from the Van Allen Probes found that, unlike the outer belt, there were no electrons with energies greater than a million electron volts in the inner belt.

Plasma waves known as whistler chorus waves are also common in our near-Earth environment. These waves can travel parallel or at an angle to the local magnetic field. The Van Allen Probes demonstrated the two types of waves cannot be present simultaneously, resulting in greater radiation belt particle scattering in certain areas.

Very low frequency chorus waves, another variety of plasma waves, can pump up the energy of electrons to millions of electronvolts. During storm conditions, the Van Allen Probes found these waves can hugely increase the energy of particles in the belts in just a few hours.  

Scientists often use computer simulation models to understand the physics behind certain phenomena. A model simulating particles in the Van Allen belts helped scientists understand how particles can be lost, replenished and trapped by Earth’s magnetic field.

The Van Allen Probes observed several cases of extremely energetic ions speeding toward Earth. Research found that these ions’ acceleration was connected to their electric charge and not to their mass.

The Sun emits faster and slower gusts of charged particles called the solar wind. Since the Sun rotates, these gusts — the fast wind — reach Earth periodically. Changes in these gusts cause the extent of the region of cold ionized gas around Earth — the plasmasphere — to shrink. Data from the Van Allen Probes showed that such changes in the plasmasphere fluctuated at the same rate as the solar rotation — every 27 days.

Though the mission has ended, scientists will use data from the Van Allen Probes for years to come. See the latest Van Allen Probes science at nasa.gov/vanallen.

what is the biggest challenge in the preparation of such a mission and how do you handle it?

Throwback Thursday: Answers to Apollo Moon Landing Questions

The first six missions to the Moon helped us answer questions about our nearest celestial neighbor, but a curious public wanted to know more about how we did it. With the help of the NASA History Office, we’ve identified some of the most frequently asked questions surrounding the first time humans walked on the surface of another world. Read on and click here to check out our post from last week and the week before. 

Why do some shadows on the Moon appear to go in different directions?

For Apollo astronauts, the Sun wasn’t the sole source of light. The high reflectivity of the lunar surface or “albedo” means that the Moon's many craters, hills and rocks bounce sunlight to wash out the stars multiple shadows on objects. The highly uneven terrain means that shadows can have slightly different lengths, as well. For example, two astronauts standing several feet away from each other can have different shadow lengths because one may be on a slope.

While the Lunar Module itself was also reflective, Apollo astronauts had yet another bright source of light: Earth! To a moonwalker, a half-full Earth would be about 20 times brighter than a full Moon as seen from our home planet. This also explains why stars are not visible in pictures. Think about it: if you wanted to photograph all the stars that can be seen from Earth, would you want to do it during a full Moon? 

Why are there no blast craters under the Lunar Modules? 

The Moon has endured billions of years of bombardment from micrometeorites and large meteorites, compacting the dust into extremely dense rock. A thin layer of fine and powdery moondust covers the ground, but the dense rock beneath this layer makes it hard to penetrate the surface. That, paired with an engine thrusting in a vacuum means that the exhaust would expand rapidly outward instead of straight down like it would on Earth. The large engine nozzle. Still, many pictures clearly show dust markings radiating from the landing site. 

Can Humans Really Survive Passing Through the Van Allen Radiation Belts?

The short answer is yes, but with protection. The Van Allen radiation belts, named after their discoverer James van Allen, are regions high above Earth’s surface that trap highly charged particles that radiate off the Sun. This energetic region contains harmful radiation that would be lethal to anybody who encountered them unprotected. Thankfully, the 12 astronauts that passed through the belts did so relatively quickly in the comfort of their shielded spacecraft that had been tested to withstand high doses of radiation. Although all six crews had to pass through the Van Allen belts, the dosimeters indicated that they received a dosage no higher than that of a chest X-ray or a single CAT scan. 

Why are we going back to the Moon?

Exploring the Moon is only the first part in our mission to expand humanity’s presence on Mars and beyond. The Moon is the ideal stepping stone for testing technology that will enable us to expand humanity’s presence on Mars and beyond.

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.

+ Learn more

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.

10 Ways to Observe the Moon for International Observe the Moon Night

On Saturday, October 5, we will host the 10th annual International Observe the Moon Night. One day each year, everyone on Earth is invited to observe and learn about the Moon together, and to celebrate the cultural and personal connections we all have with our nearest celestial neighbor! This year is particularly special as we mark the 50th anniversary of the Apollo 11 Moon landing while looking forward to our Artemis program, which will send the first woman and next man to the Moon.

There are many ways to participate in International Observe the Moon Night. You can attend an event, host your own or just look up! Here are 10 of our favorite ways to observe the Moon.

1. Look up

The simplest way to observe the Moon is simply to look up. The Moon is the brightest object in our night sky, the second brightest in our daytime sky and can be seen from all around the world — from the remote and dark Atacama Desert in Chile to the brightly lit streets of Tokyo. On October 5, we have a first quarter Moon, which means that the near side of the Moon will be 50 percent illuminated. The first quarter Moon is a great phase for evening observing. Furthermore, the best lunar observing is typically along the Moon's terminator (the line between night and day) where shadows are the longest, rather than at full Moon. See the Moon phase on October 5 or any other day of the year!

2. Peer through a telescope or binoculars

Is it cloudy? Luckily, you can observe the Moon from the comfort of your own home. The Virtual Telescope Project will livestream the Moon from above the Roman skyline. Or, you can take and process your own lunar images with the MicroObservatory Robotic Telescopes. Would you prefer a movie night? There are many films that feature our nearest neighbor. Also, you can spend your evening with our lunar playlist on YouTube or this video gallery, learning about the Moon’s role in eclipses, looking at the Moon phases from the far side and seeing the latest science portrayed in super high resolution.

5. Touch the topography

Treat your ears this International Observe the Moon Night. Our audio series, NASA Explorers: Apollo features personal stories from the Apollo era to now, including yours! You can participate by recording and sharing your own experiences of Apollo with us. Learn some lunar science with the second season of our Gravity Assist podcast with NASA Chief Scientist, Jim Green. Make a playlist of Moon-themed songs. For inspiration, check out this list of lunar tunes. We also recommend LRO’s official music video, The Moon and More, featuring Javier Colon, season 1 winner of NBC’s “The Voice.” Or you can watch this video featuring “Clair de Lune,” by French composer Claude Debussy, over and over.

8. Take a virtual field trip

Plan a lunar hike with Moon Trek. Moon Trek is an interactive Moon map made using NASA data from our lunar spacecraft. Fly anywhere you’d like on the Moon, calculate the distance or the elevation of a mountain to plan your lunar hike, or layer attributes of the lunar surface and temperature. If you have a virtual reality headset, you can experience Moon Trek in 3D.  

9. See the Moon through the eyes of a spacecraft

Visible light is just one tool that we use to explore our universe. Our spacecraft contain many different types of instruments to analyze the Moon’s composition and environment. Review the Moon’s gravity field with data from the GRAIL spacecraft or decipher the maze of this slope map from the laser altimeter onboard LRO. This collection from LRO features images of the Moon’s temperature and topography. You can learn more about the different NASA missions to explore the Moon here.

10. Continue your observations throughout the year

The James Webb Space Telescope has just completed a successful first year of science. Let’s celebrate by seeing the birth of Sun-like stars in this brand-new image from the Webb telescope!

This is a small star-forming region in the Rho Ophiuchi cloud complex. At 390 light-years away, it's the closest star-forming region to Earth. There are around 50 young stars here, all of them similar in mass to the Sun, or smaller. The darkest areas are the densest, where thick dust cocoons still-forming protostars. Huge red bipolar jets of molecular hydrogen dominate the image, appearing horizontally across the upper third and vertically on the right. These occur when a star first bursts through its natal envelope of cosmic dust, shooting out a pair of opposing jets into space like a newborn first stretching her arms out into the world. In contrast, the star S1 has carved out a glowing cave of dust in the lower half of the image. It is the only star in the image that is significantly more massive than the Sun.

Thanks to Webb’s sensitive instruments, we get to witness moments like this at the beginning of a star’s life. One year in, Webb’s science mission is only just getting started. The second year of observations has already been selected, with plans to build on an exciting first year that exceeded expectations. Here’s to many more years of scientific discovery with Webb.
