More than Just Dust in the Wind

From space, we can see a swirling brown mass making its way across the Atlantic – dust from the Sahara Desert – the largest hot desert in the world. It’s a normal phenomenon. Every year, winds carry millions of tons of dust from North Africa, usually during spring and summer in the Northern Hemisphere.

June 2020 has seen a massive plume of dust crossing the ocean. It’s so large it’s visible from one million miles away in space.

Dust clouds this large can affect air quality in regions where the dust arrives. The particles can also scatter the Sun’s light, making sunrises and sunsets more vibrant.

Dust particles in the air are also known as aerosols. We can measure aerosols, including dust, sea salt and smoke, from satellites and also use computer models to study how they move with the wind.

Following the transport of dust from space shows us how one of the driest places on Earth plays a role in fertilizing the Amazon rainforest. There are minerals in Saharan dust, like phosphorous, that exist in commercial fertilizers, helping seed the rainforest.

Tour NASA with One Direction

You might have heard, One Direction filmed their ‘Drag Me Down’ music video at NASA’s Johnson Space Center, and we know you’re dying to take a tour of everything they saw. So, here we go…

1) Space Exploration Vehicle (SEV)

Even though Louis is roving around Johnson Space Center in our Space Exploration Vehicle, its intended destination is quite different. The SEV will be used for in-space missions and for surface explorations of planetary bodies, including near-Earth asteroids and Mars!

2) Robonaut

Harry and Robonaut bonded during their visit to Johnson Space Center for the filming of their music video. This robot will help humans work and explore in space. Working side by side with humans, or going where the risks are too great for people, robots will make it so we never get ‘dragged down’!

3) Partial Gravity Simulator & Space Station Mockup Bike

You can find Niall floating around in our Partial Gravity Simulator, aka POGO, in the new music video. This tool is used to provide accurate simulations of reduced gravity. Astronauts use this for training and to learn how to perform tasks in space.

While Niall floats with POGO, Liam is training on the International Space Station Mockup Bike, aka CEVIS. This bike provides aerobic exercise and is used to countermeasure the harmful effects of exposure to microgravity while on the space station.

4) Orion Spacecraft

The Orion spacecraft will be the first of its kind that will carry humans to deep space and to Mars! It will be the safest, most advanced spacecraft ever built, and Harry, Niall, Louis and Liam all got to check it out.

5) T-38 Jets

Flying these T-38 jet trainers are an important part of preparing to be an astronaut. Flying and landing them acts as a real-life simulation for practicing spacecraft operations. They can even fly at supersonic up to Mach 1.6, and can put their pilots through more than seven Gs! 

NASA Spotlight: Brandon Rodriguez, Jet Propulsion Laboratory Education Specialist 

Brandon Rodriguez is an education specialist at our Jet Propulsion Laboratory (JPL) in Pasadena, California where he provides resources and training to K-12 schools across the Southwest. Working with a team at JPL, he develops content for classroom teachers, visits schools and speaks with students and trains future teachers to bring NASA into their classroom. When he’s not in the classroom, Brandon’s job takes him on research expeditions all around the world, studying our planet’s extreme environments.  

Fun fact: Brandon wakes up every morning to teach an 8 a.m. physics class at a charter school before heading to JPL and clocking in at his full time job. When asked why? He shared, “The truth is that I really feel so much better about my role knowing that we’re not ‘telling’ teachers what to do from our ivory tower. Instead, I can “share” with teachers what I know works not just in theory, but because I’m still there in the classroom doing it myself.” - Brandon Rodriguez

Brandon took time from exciting the next generation of explorers to answer some questions about his life and his career: 

What inspired you to work in the educational department at NASA?

I was over the moon when I got a call from NASA Education. I began my career as a research scientist, doing alternative energy work as a chemist. After seven years in the field, I began to feel as if I had a moral responsibility to bring access to science to a the next generation. To do so, I quit my job in science and became a high school science teacher. When NASA called, they asked me if I wanted a way to be both a scientist and an educator- how could I resist?

You were born in Venezuela and came to the U.S. when you were 12 years old. Can you tell us the story of why and how you came to America?

I haven't been back to Venezuela since I was very young, which has been very difficult for me. Being an immigrant in the USA sometimes feels like you're an outsider of both sides: I'm not truly Latin, nor am I an American. When I was young, I struggled with this in ways I couldn't articulate, which manifested in a lot of anger and got me in quite a bit of trouble. Coming to California and working in schools that are not only primarily Latinx students, but also first generation Latinx has really helped me process that feeling, because it's something I can share with those kids. What was once an alienating force has become a very effective tool for my teaching practice.

Does your job take you on any adventures outside of the classroom and if so, what have been your favorite endeavors?

I'm so fortunate that my role takes me all over the world and into environments that allow to me to continue to develop while still sharing my strengths with the education community. I visit schools all over California and the Southwest of the USA to bring professional development to teachers passionate about science. But this year, I was also able to join the Ocean Exploration Trust aboard the EV Nautilus as we explored the Pacific Remote Island National Marine Monument. We were at sea for 23 days, sailing from American Samoa to Hawaii, using submersible remotely operated vehicles to explore the ocean floor.

We collected coral and rock samples from places no one has ever explored before, and observed some amazing species of marine creatures along the way.

What keeps you motivated to go to work every day?

There's no greater motivation than seeing the product of your hard work, and I get that everyday through students. I get to bring them NASA research that is "hot off the press" in ways that their textbooks never can. They see pictures not online or on worksheets, but from earlier that day as I walked through JPL. It is clearly that much more real and tangible to them when they can access it through their teacher and their community.

Do you have any tips for people struggling with their science and math classes? 

As someone who struggled- especially in college- I want people to know that what they struggle with isn't science, it's science classes. The world of research doesn't have exams; it doesn't have blanks to be filled in or facts to be memorized. Science is exploring the unknown. Yes, of course we need the tools to properly explore, and that usually means building a strong academic foundation. But it helped me to differentiate the end goal from the process: I was bad at science tests, but I wanted to someday be very good at science. I could persevere through the former if it got me to the latter.

If you could safely visit any planet, star, or solar system, where would you visit and what would you want to learn?

Europa, without a doubt. Imagine if we found even simple life once more in our solar system- and outside of the habitable zone, no less. What would this mean for finding life outside of our solar system as a result? We would surely need to conclude that our sky is filled with alien worlds looking back at us.

Is there a moment or project that you feel defined (or significantly impacted) your career up to today?

While I never worked closely with the mission, Insight was a really important project for me. It's the first time while at JPL I was able to see the construction, launch and landing of a mission.

If you could name a spaceship, what would you name it?

For as long as I can remember, I've been watching and reading science fiction, and I continue to be amazed at how fiction informs reality. How long ago was it that in Star Trek, the crew would be handing around these futuristic computer tablets that decades later would become common iPads?  In their honor, I would be delighted if we named a ship Enterprise.

Thanks so much Brandon!

Land is Sliding, Tell Us Where!

Summer in the northern hemisphere brings monsoon season, causing heavy rains and flooding that trigger landslides. Next time you see a landslide in the news, online, or in your neighborhood, submit it to our citizen science project Landslide Reporter to build the largest open global landslide catalog and help us and the public learn more about when and where they occur.

Rainfall is the most common cause of landslides.

After a storm, the soil and rock on a slope can become saturated with water and begin to slide downwards, posing a danger to people and destroying roads, houses and access to electricity and water supplies.

We have been monitoring rainfall from space for decades.

Orbiting the Earth right now, the Global Precipitation Measurement (GPM) mission is a group of 10 satellites that measure rain, snow, sleet and other precipitation worldwide every three hours. This data tells us where and when heavy rain is falling and if it could lead to disasters.

What can rainfall data tell us about landslides?

We're using GPM data to understand where and when landslides are happening. A global landslide model uses information about the environment and rainfall to anticipate where landslides are likely to happen anytime around the world every three hours.

To improve the global landslide model and other landslide research, NASA is looking for citizen scientists like you!

If you find a landslide reported online or in your neighborhood, you can provide the event details in Landslide Reporter, our citizen science project.

Your detailed reports are added into an open global landslide inventory available at Landslide Viewer. We use citizen science contributions along with other landslide data to check our prediction model so we can have a better picture of how rainfall, slope steepness, forest cover, and geology can trigger a landslide.

Because the data is open, anyone can use the data for research or response.

When you report a landslide, you improve our collection of landslide data for everyone.

Help support landslide efforts worldwide by contributing to Landslide Reporter, and you can help inform decisions that could save lives and property today! Learn more about the project at https://landslides.nasa.gov. You can also follow the project on Twitter and Facebook.

The Artemis Story: Where We Are Now and Where We’re Going

Using a sustainable architecture and sophisticated hardware unlike any other, the first woman and the next man will set foot on the surface of the Moon by 2024. Artemis I, the first mission of our powerful Space Launch System (SLS) rocket and Orion spacecraft, is an important step in reaching that goal.

As we close out 2019 and look forward to 2020, here’s where we stand in the Artemis story — and what to expect in 2020. 

Cranking Up The Heat on Orion

The Artemis I Orion spacecraft arrived at our Plum Brook Station in Sandusky, Ohio, on Tuesday, Nov. 26 for in-space environmental testing in preparation for Artemis I.

This four-month test campaign will subject the spacecraft, consisting of its crew module and European-built service module, to the vacuum, extreme temperatures (ranging from -250° to 300° F) and electromagnetic environment it will experience during the three-week journey around the Moon and back. The goal of testing is to confirm the spacecraft’s components and systems work properly under in-space conditions, while gathering data to ensure the spacecraft is fit for all subsequent Artemis missions to the Moon and beyond. This is the final critical step before the spacecraft is ready to be joined with the Space Launch System rocket for this first test flight in 2020!

Bringing Everyone Together

On Dec. 9, we welcomed members of the public to our Michoud Assembly Facility in New Orleans for #Artemis Day and to get an up-close look at the hardware that will help power our Artemis missions. The 43-acre facility has more than enough room for guests and the Artemis I, II, and III rocket hardware! NASA Administrator Jim Bridenstine formally unveiled the fully assembled core stage of our SLS rocket for the first Artemis mission to the Moon, then guests toured of the facility to see flight hardware for Artemis II and III. The full-day event — complete with two panel discussions and an exhibit hall — marked a milestone moment as we prepare for an exciting next phase in 2020.

Rolling On and Moving Out

Once engineers and technicians at Michoud complete functional testing on the Artemis I core stage, it will be rolled out of the Michoud factory and loaded onto our Pegasus barge for a very special delivery indeed. About this time last year, our Pegasus barge crew was delivering a test version of the liquid hydrogen tank from Michoud to NASA’s Marshall Space Flight Center in Huntsville for structural testing. This season, the Pegasus team will be transporting a much larger piece of hardware — the entire core stage — on a slightly shorter journey to the agency’s nearby Stennis Space Center near Bay St. Louis, Mississippi.

Special Delivery

Why Stennis, you ask? The giant core stage will be locked and loaded into the B2 Test Stand there for the landmark Green Run test series. During the test series, the entire stage, including its extensive avionics and flight software systems, will be tested in full. The series will culminate with a hot fire of all four RS-25 engines and will certify the complex stage “go for launch.” The next time the core stage and its four engines fire as one will be on the launchpad at NASA’s Kennedy Space Center in Florida.

Already Working on Artemis II

As Orion and SLS make progress toward the pad for Artemis I, employees at NASA centers and large and small companies across America are hard at work assembling and manufacturing flight hardware for Artemis II and beyond.  The second mission of SLS and Orion will be a test flight with astronauts aboard that will go around the Moon before returning home. Our work today will pave the way for a new generation of moonwalkers and Artemis explorers.

NASA: 2016 Look Ahead

The work we do, and will continue in 2016, helps the United States maintain its world leadership in space exploration and scientific discovery. Here’s an overview of what we have planned for the coming year:

Our Journey to Mars

We’re developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s. Mars is a rich destination for scientific discovery and robotic and human exploration as we expand our presence into the solar system. Its formation and evolution are comparable to Earth, helping us learn more about our own planet’s history and future.

Work and Research on the International Space Station

The International Space Station is a unique place – a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. In 2016, we will continue our groundbreaking research on the orbiting laboratory.

Returning Human Spaceflight Launches to American Soil

Our Commercial Crew Program is working with the American aerospace industry as companies develop and operate a new generation of spacecraft and launch systems capable of carrying crews to low-Earth orbit and the International Space Station. Commercial transportation to and from the station will provide expanded utility, additional research time and broader opportunities of discovery on the orbiting laboratory.

Studying Our Earth Right Now

We use the vantage point of space to increase our understanding of our home planet, improve lives and safeguard our future. In 2016, we will continue to monitor Earth’s vital signs from land, air and space with a fleet of satellites and ambitious airborne and ground-based observation campaigns.

Fostering Groundbreaking Technology Development

Sustained investments in NASA technology advances our space exploration, science and aeronautics capabilities. Our technology development also supports the nation's innovation economy by creating solutions that generate tangible benefits for life on earth. In 2016, we will continue to invest in the future of innovation.

Breakthroughs in Aeronautics

Thanks to our advancements in aeronautics, today’s aviation industry is better equipped than ever to safely and efficiently transport all those passengers to their destinations. In fact, every U.S. aircraft flying today and every U.S. air traffic control tower uses NASA-developed technology in some way. In 2016, we will continue making these breakthroughs in aeronautics.

Discoveries in Our Solar System and Beyond

This year we will continue exploring our solar system and beyond to unravel the mysteries of our universe. We are looking to answer key questions about our home planet, neighboring planets in our solar system and more!

Astronaut Journal Entry - Launch & Docking

Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph. Below you will find a real journal entry, written in space, by NASA astronaut Scott Tingle.

To read more entires from this series, visit our Space Blogs on Tumblr.

The launch went as planned. Our Soyuz spacecraft did a great job getting the three of us to the International Space Station (ISS).  

A week later, it all seems like a blur. The bus driver played me a video of my family and friends delivering their good luck messages. After exiting the bus at the launch pad, I was fortunate to have the Soyuz chief designer (Roman) and NASA’s associate administrator for Human Exploration and Operations (Bill Gerstenmaier) walk me to the stairs and elevator that would take us to the top of the rocket for boarding. The temperature at the pad was approximately -17 degrees centigrade, and we were wearing the Russian Polar Bear suits over our spacesuits in order to stay warm. Walking in these suits is a little hard, and I was happy to have Roman and Bill helping me. 

We walked into the fog created by the systems around the rocket, climbed the ladder, and waved goodbye. My last words before launch were to Bill, “Boiler Up!”. Bill is a fellow and very well-known Boilermaker. We strapped in, and the launch and docking were nominal. But I will add that the second stage cutoff and separation, and ignition of the third stage was very exciting. We were under approximately 4 Gs when the engine cutoff, which gave us a good jolt forward during the deceleration and then a good jolt back into the seat after the third stage ignited. I looked at Anton and we both began to giggle like school children.

We spent two days in orbit as our phase angle aligned with ISS. Surprisingly, I did not feel sick. I even got 4 hours of sleep the first night and nearly 6 hours the second night. Having not been able to use my diaper while sitting in the fetal position during launch, it was nice to get out of our seats and use the ACY (Russian toilet). Docking was amazing. I compared it to rendezvousing on a tanker in a fighter jet, except the rendezvous with ISS happened over a much larger distance. As a test pilot, it was very interesting to watch the vehicle capture and maintain the centerline of ISS’s MRM-1 docking port as well as capturing and maintaining the required speed profile. 

Just like landing at the ship, I could feel the vehicle’s control system (thrusters) making smaller and faster corrections and recorrections. In the flight test world, this is where the “gains” increase rapidly and where any weaknesses in the control system will be exposed. It was amazing to see the huge solar arrays and tons of equipment go by my window during final approach. What an engineering marvel the ISS is. Smooth sailing right into the docking port we went!  

About an hour later, after equalizing pressures between the station and Soyuz, we opened the hatch and greeted our friends already onboard. My first view of the inside of the space station looked pretty close to the simulators we have been training in for the last several years. My first words were, “Hey, what are you guys doing at Building 9?”. Then we tackled each other with celebratory hugs!

What Science is Launching to Space?

The tenth SpaceX cargo resupply mission launched to the International Space Station on Feb. 18, and is carrying science ranging from protein crystal growth studies to Earth science payloads. Here’s a rundown of some of the highlights heading to the orbiting laboratory.

The CASIS PCG 5 investigation will crystallize a human monoclonal antibody, developed by Merck Research Labs, that is currently undergoing clinical trials for the treatment of immunological disease. Results from this investigation have the potential to improve the way monoclonal antibody treatments are administered on Earth.

Without proteins, the human body would be unable to repair, regulate or protect itself. Crystallizing proteins provides better views of their structure, which helps scientists to better understand how they function. Often times, proteins crystallized in microgravity are of higher quality than those crystallized on Earth. LMM Biophysics 1 explores that phenomena by examining the movement of single protein molecules in microgravity. Once scientists understand how these proteins function, they can be used to design new drugs that interact with the protein in specific ways and fight disease.

Much like LMM Biophysics 1, LMM Biophysics 3 aims to use crystallography to examine molecules that are too small to be seen under a microscope, in order to best predict what types of drugs will interact best with certain kinds of proteins. LMM Biophysics 3 will look specifically into which types of crystals thrive and benefit from growth in microgravity, where Earth’s gravity won’t interfere with their formation. Currently, the success rate is poor for crystals grown even in the best of laboratories. High quality, space-grown crystals could improve research for a wide range of diseases, as well as microgravity-related problems such as radiation damage, bone loss and muscle atrophy.

Nanobiosym Predictive Pathogen Mutation Study (Nanobiosym Genes) will analyze two strains of bacterial mutations aboard the station, providing data that may be helpful in refining models of drug resistance and support the development of better medicines to counteract the resistant strains.

During the Microgravity Expanded Stem Cells investigation, crew members will observe cell growth and morphological characteristics in microgravity and analyze gene expression profiles of cells grown on the station. This information will provide insight into how human cancers start and spread, which aids in the development of prevention and treatment plans. Results from this investigation could lead to the treatment of disease and injury in space, as well as provide a way to improve stem cell production for human therapy on Earth.

The Lightning Imaging Sensor will measure the amount, rate and energy of lightning as it strikes around the world. Understanding the processes that cause lightning and the connections between lightning and subsequent severe weather events is a key to improving weather predictions and saving life and property. 

From the vantage of the station, the LIS instrument will sample lightning over a wider geographical area than any previous sensor.

Future robotic spacecraft will need advanced autopilot systems to help them safely navigate and rendezvous with other objects, as they will be operating thousands of miles from Earth. 

The Raven (STP-H5 Raven) studies a real-time spacecraft navigation system that provides the eyes and intelligence to see a target and steer toward it safely. Research from Raven can be applied toward unmanned vehicles both on Earth and in space, including potential use for systems in NASA’s future human deep space exploration.

SAGE III will measure stratospheric ozone, aerosols, and other trace gases by locking onto the sun or moon and scanning a thin profile of Earth’s atmosphere.

These measurements will allow national and international leaders to make informed policy decisions regarding the protection and preservation of Earth’s ozone layer. Ozone in the atmosphere protects Earth’s inhabitants, including humans, plants and animals, from harmful radiation from the sun, which can cause long-term problems such as cataracts, cancer and reduced crop yield.

Tissue Regeneration-Bone Defect (Rodent Research-4) a U.S. National Laboratory investigation sponsored by the Center for the Advancement of Science in Space (CASIS) and the U.S. Army Medical Research and Materiel Command, studies what prevents other vertebrates such as rodents and humans from re-growing lost bone and tissue, and how microgravity conditions impact the process. 

Results will provide a new understanding of the biological reasons behind a human’s inability to grow a lost limb at the wound site, and could lead to new treatment options for the more than 30% of the patient.
