Solar System: Things To Know This Week

People of OSIRIS-REx

As OSIRIS-REx closes in on its target destination—asteroid Bennu—anticipation is building for the first-ever, close-up glimpse of this small world. It took thousands of people to come this far. Get to know a few members of the team:

1. Carl Hergenrother, Astronomy Working Group Lead & Strategic and Tactical Scientist

Job Location: University of Arizona, Tucson Expertise: Asteroids & Comets Time on mission: Since before there was a mission Age: 45 Hometown: Oakland, New Jersey

“When you’re observing Bennu with a telescope, you see it as a dot. … So when it actually becomes its own little world, it’s really exciting—and almost a little sad. Up until that point, it can be anything. And now, there it is and that’s it.”

2. Heather Roper, Graphic Designer

Job Location: University of Arizona, Tucson Job Title: Graphic Designer Expertise: Visual Communications Time on mission: 5 years Age: 25 Hometown: Tucson, Arizona

“I really like the challenge of visually depicting the science of the mission and getting to show people things that we can’t see.”

3. Jason Dworkin, Project Scientist

Job Location: NASA’s Goddard Space Flight Center, Greenbelt, Maryland Expertise: Origin-of-life Chemistry Time on mission: Since before there was a mission Age: 49 Hometown: Houston, Texas

"In 10th grade, I had to do a science fair project for biology class. … I wanted to expand on chemistry experiments from old journal papers; but that could have been dangerous. I got in touch with … a pioneering scientist in origin-of-life research and asked for advice. He was worried that I would accidentally injure myself, so he invited me into his lab . . . that helped set my career.”

4. Sara Balram Knutson, Science Operations Lead Engineer

Job Location: University of Arizona, Tucson Expertise: Aerospace Engineering Time on mission: 6 years Age: 31 Hometown: Vacaville, California

“My dad was in the Air Force, so I grew up being a bit of an airplane nerd. When I was in high school, I really liked math, science, and anything having to do with flight. I looked for a field where I could combine all those interests and I found aerospace engineering.”

5. Nancy Neal Jones, Public Affairs Lead

Job Location: NASA’s Goddard Space Flight Center, Greenbelt, Maryland Expertise: Science Communications Time on mission: 7 years Age: 51 Hometown: New York, New York

“We’re going to a pristine asteroid to take a sample to bring to Earth. This means that my children and grandchildren, if they decide to go into the sciences, may have an opportunity analyze the Bennu samples.”

6. Javier Cerna, Communications System Engineer

Job Location: Lockheed Martin Corporation, Littleton, Colorado Expertise: Electrical Engineering Time on mission: Since before there was a mission Age: 37 Hometown: Born in Mexico City, and raised in Los Angeles, and Las Cruces, New Mexico

“One thing we do is evaluate how strong the signal from the spacecraft is—kind of like checking the strength of the WiFi connection. Basically, we’re ensuring that the link from the spacecraft to the ground, and vice versa, stays strong.”

7. Jamie Moore, Contamination Control Engineer

Job Location: Lockheed Martin Corporation, Littleton, Colorado Expertise: Chemistry Time on mission: 5 years Age: 32 Hometown: Apple Valley, Minnesota & Orlando, Florida

“I was there for just about every deployment of the sampling hardware to make sure it was kept clean and to evaluate the tools engineers were using. I even went to Florida with the spacecraft to make sure it stayed clean until launch.”

8. Mike Moreau, Flight Dynamics System Manager

Job Location: NASA’s Goddard Space Flight Center, Greenbelt, Maryland; Littleton, Colorado Expertise: Mechanical and aerospace engineering Time on mission: 5 years Age: 47 Hometown: Swanton, Vermont

“I grew up on a dairy farm in Vermont, which is a world away from working for NASA. But I can trace a lot of my success as an engineer and a leader back to things that I learned on my dad’s farm.”

9. Johnna L. McDaniel, Contamination Control Specialist

Job Location: NASA’s Kennedy Space Center, Florida Expertise: Anti-Contamination Cleaning Time on Mission: 4 months Age: 53 Hometown: Cocoa, Florida

“The clothing requirements depend on the payload. With OSIRIS-Rex, we could not wear any items made with nylon. This was because they have amino acid-based polymers in them and would have contaminated the spacecraft. I even had a special bucket for mopping.”

10. Annie Hasten, Senior Financial Analyst

Job Location: Lockheed Martin Corporation, Steamboat Springs, Colorado Expertise: Business Time on Mission: 1.5 years Age: 30 Hometown: Littleton, Colorado

“I think it’s a pleasure to work with people who are so intensely passionate about their jobs. These engineers are doing their dream jobs, so you feed off of that positive energy.”

Our Sun is More than Meets the Eye

The Sun may look unchanging to us here on Earth, but that’s not the whole story.

In visible light – the light our eyes can see – the Sun looks like an almost featureless orange disk, peppered with the occasional sunspot. (Important note: Never look at the Sun directly, and always use a proper filter for solar viewing – or tune in to our near-real time satellite feeds!)

But in other kinds of light, it’s a different picture. The Sun emits light across the electromagnetic spectrum, including the relatively narrow range of light we can see, as well as wavelengths that are invisible to our eyes. Different wavelengths convey information about different components of the Sun’s surface and atmosphere, so watching the Sun in multiple types of light helps us paint a fuller picture.

Watching the Sun in these wavelengths reveals how active it truly is. This image, captured in a wavelength of extreme ultraviolet light at 131 Angstroms, shows a solar flare. Solar flares are intense bursts of light radiation caused by magnetic events on the Sun, and often associated with sunspots. The light radiation from solar flares can disturb part of Earth’s atmosphere where radio signals travel, causing short-lived problems with communications systems and GPS.

Looking at the Sun in extreme ultraviolet light also reveals structures like coronal loops (magnetic loops traced out by charged particles spinning along magnetic field lines)…

…solar prominence eruptions…

…and coronal holes (magnetically open areas on the Sun from which solar wind rushes out into space).

Though extreme ultraviolet light shows the Sun's true colors, specialized instruments let us see some of the Sun's most significant activity in visible light.

A coronagraph is a camera that uses a solid disk to block out the Sun’s bright face, revealing the much fainter corona, a dynamic part of the Sun’s atmosphere. Coronagraphs also reveal coronal mass ejections, or CMEs, which are explosions of billions of tons of solar material into space. Because this material is magnetized, it can interact with Earth’s magnetic field and trigger space weather effects like the aurora, satellite problems, and even – in extreme cases – power outages.

The Sun is also prone to bursts of energetic particles. These particles are blocked by Earth’s magnetic field and atmosphere, but they could pose a threat to astronauts traveling in deep space, and they can interfere with our satellites. This clip shows an eruption of energetic particles impacting a Sun-observing satellite, creating the 'snow' in the image.

We keep watch on the Sun 24/7 with a fleet of satellites to monitor and better understand this activity. And this summer, we’re going one step closer with the launch of Parker Solar Probe, a mission to touch the Sun. Parker Solar Probe will get far closer to the Sun than any other spacecraft has ever gone – into the corona, within 4 million miles of the surface – and will send back unprecedented direct measurements from the regions thought to drive much of the Sun’s activity. More information about the fundamental processes there can help round out and improve models to predict the space weather that the Sun sends our way.

Keep up with the latest on the Sun at @NASASun on Twitter, and follow along with Parker Solar Probe’s last steps to launch at nasa.gov/solarprobe.

Celebrating 81 Years of Ingenuity

Eighty-one years ago, our world-class research center in California’s Silicon Valley was born. Ground broke on Ames Research Center on Dec. 20, 1939. It was the second aeronautical laboratory established by the National Advisory Committee for Aeronautics to perform fundamental research on all things flight. From its very beginnings, Ames was a place for innovation. Tests performed in its wind tunnels transformed military aircraft during World War II and paved the way for air travel at supersonic speeds. In the 1950s and ‘60s, its researchers looked to the stars and came up with new designs and materials for spacecraft that would make human spaceflight a reality. Fast-forward to the present, and the center contributes to virtually every major agency mission through its expertise in spacecraft entry systems, robotics, aeronautics, supercomputing, and so much more! Here are things to know about Ames.

Ames Research Center is home to the world’s largest wind tunnel.

The center is also home to Pleiades, our most powerful supercomputer.

Its modeling and simulation work plays a key role in designing new vehicles for exploring space.

The center invented heat shield materials for landing rovers on Mars.

It built robots to assist astronauts living and working aboard the International Space Station.

It launched a space telescope that revealed thousands of worlds beyond our solar system.

The center has also led multiple missions to explore the Moon.

It found water on the Moon ... more than once, and in places no one would have guessed.

The Volatiles Investigating Polar Exploration Rover is the latest lunar exploration mission led by Ames. Launching in 2023, the mobile robot will search for water ice inside craters and other places at the Moon's South Pole. Its survey will help pave the way for astronaut missions to the lunar surface beginning in 2024 as part of the Artemis program.

What’s a Blood Moon? And Other Lunar Eclipse Questions.

Tonight, Australians, Africans, Europeans, Asians and South Americans will have the opportunity to see the longest lunar eclipse of the century. Sorry North America. 

Lunar eclipses occur about 2-4 times per year, when the Moon passes into the Earth’s shadow. In order to see a lunar eclipse, you must be on the night side of the Earth, facing the Moon, when the Earth passes in between the Moon and the Sun. Need help visualizing this? Here you go:

What’s the difference between a solar eclipse and a lunar eclipse?

An easy way to remember the difference between a solar eclipse and a lunar eclipse is that the word ‘eclipse’ refers to the object that is being obscured. During a solar eclipse, the Moon blocks the Sun from view. During a lunar eclipse, the Earth’s shadow obscures the Moon.

Why does the Moon turn red?  

You may have heard the term ‘Blood Moon’ for a lunar eclipse. When the Moon passes into the Earth’s shadow, it turns red. This happens for the exact same reason that our sunrises and sunsets here on Earth are brilliant shades of pinks and oranges. During a lunar eclipse, the only light reaching the Moon passes through the Earth’s atmosphere. The bluer, shorter wavelength light scatters and the longer wavelength red light passes through and makes it to the Moon.

What science can we learn from a lunar eclipse?

"During a lunar eclipse, the temperature swing is so dramatic that it’s as if the surface of the Moon goes from being in an oven to being in a freezer in just a few hours,” said Noah Petro, project scientist for our Lunar Reconnaissance Orbiter, or LRO, at our Goddard Space Flight Center in Greenbelt, Maryland.

The Diviner team from LRO measures temperature changes on the Moon through their instrument on the spacecraft as well as through a thermal camera on Earth. How quickly or slowly the lunar surface loses heat helps scientists determine characteristics of lunar material, including its composition and physical properties.

When is the next lunar eclipse?

North Americans, don’t worry. If skies are clear, you can see the next lunar eclipse on January 21, 2019. The eclipse will be visible to North Americans, South Americans, and most of Africa and Europe.

You seem to have spent a lot of time in some pretty isolated locations during your career, what are some challenges to that? Was there anything you enjoyed about it?

What future missions are you looking forward to the most?

Marcos Berrios

Marcos Berrios is from Guaynabo, Puerto Rico, and received his Ph.D. in aeronautics and astronautics from Stanford. Berríos has logged over 1,400 hours of flight time in over 20 different aircraft. https://go.nasa.gov/49DEAAt

Space Station Research: Air and Space Science

Each month, we highlight a different research topic on the International Space Station. In June, our focus is Air and Space Science.

How is the space station being used to study space? Studies in fundamental physics address space, time, energy and the building blocks of matter. Recent astronomical observation and cosmological models strongly suggest that dark matter and dark energy, which are entities not directly observed and completely understood, dominate these interactions at the largest scales.

The space station provides a modern and well-equipped orbiting laboratory for a set of fundamental physics experiments with regimes and precision not achievable on the ground. 

For example, the CALorimetric Electron Telescope (CALET) is an astrophysics mission that searches for signatures of dark matter (pictured above). It can observe discrete sources of high energy particle acceleration in our local region of the galaxy. 

How is the space station contributing to aeronautics? It provides a long-duration spaceflight environment for conducting microgravity physical science research. This environment greatly reduces buoyancy-driven convection and sedimentation in fluids. By eliminating gravity, space station allows scientists to advance our knowledge in fluid physics and materials science that could lead to better designated air and space engines; stronger, lighter alloys; and combustion processes that can lead to more energy-efficient systems.

How is the space station used to study air? The Cloud-Aerosol Transport System (CATS) is a laster remote-sensing instrument, or lidar, that measures clouds and tiny aerosol particles in the atmosphere such as pollution, mineral dust and smoke. These atmospheric components play a critical part in understanding how human activities such as fossil fuel burning contribute to climate change.

The ISS-RapidScat is an instrument that monitors winds for climate research, weather predictions and hurricane monitoring from the International Space Station.
