Moonbound: One Year Since Artemis I

Meet Megan McArthur, NASA Astronaut & Crew-2 Pilot

NASA astronaut Megan McArthur will launch on Friday, April 23 to the International Space Station as the pilot for NASA’s SpaceX Crew-2 mission! This is the second crew rotation flight with astronauts on the Crew Dragon spacecraft and the first launch with two international partners as part of the agency’s Commercial Crew Program. McArthur is responsible for spacecraft systems and performance and is assigned to be a long-duration space station crew member. While this is her first trip to the space station, McArthur’s career has prepared her well for this important role on the Crew-2 team!

McArthur was born in Honolulu, Hawaii and grew up in California. She is a former Girl Scout and has a Bachelor of Science in Aerospace Engineering from the University of California, Los Angeles and a Ph.D. in Oceanography from the University of California, San Diego where she performed research activities at the Scripps Institution of Oceanography.

While in graduate school, McArthur conducted research, served as Chief Scientist for at-sea data collection operations, and planned and led diving operations. She also volunteered at the Birch Aquarium at Scripps, conducting educational demonstrations for the public from inside a 70,000-gallon exhibit tank of the California Kelp Forest. Her experience conducting research in extreme conditions will certainly come in handy once she’s aboard the space station, as a big part of the astronauts’ job involves running research experiments in microgravity.

McArthur was selected as a NASA astronaut in 2000 and flew her first spaceflight aboard STS-125, the final space shuttle mission to service the Hubble Space Telescope. She worked as the flight engineer during launch and landing, and also served as the shuttle's robotic arm operator as she carefully retrieved the telescope and placed it in the shuttle’s cargo bay for servicing. The successful mission improved the telescope's capabilities and extended its life – and Hubble is still helping us make discoveries about our universe.

Mathematician. Leader. Heroine. Remembering Hidden Figure Katherine Johnson

Tonight, count the stars and remember a trailblazer. 

We're saddened by the passing of celebrated #HiddenFigures mathematician Katherine Johnson. She passed away at 101 years old. 

An America hero, Johnson's legacy of excellence broke down racial and social barriers while helping get our space agency off the ground.

Once a "human computer", she famously calculated the flight trajectory for Alan Shepard, the first American in space.

And when we began to use electronic computers for calculations, astronaut John Glenn said that he’d trust the computers only after Johnson personally checked the math.

As a girl, Katherine Johnson counted everything. As a mathematician, her calculations proved critical to our early successes in space travel.

With slide rules and pencils, Katherine Johnson’s brilliant mind helped launch our nation into space. No longer a Hidden Figure, her bravery and commitment to excellence leaves an eternal legacy for us all.

"We will always have STEM with us. Some things will drop out of the public eye and will go away, but there will always be science, engineering and technology. And there will always, always be mathematics." - Katherine Johnson 1918 -2020 

May she rest in peace, and may her powerful legacy inspire generations to come! What does Katherine Johnson’s legacy mean to you? Share in the comments.

Questions coming up from….

@teamadamsperret: Congrats on your PhD!! When people ask what you do, what's your reply?

@Anonymous: How does it feel, working in NASA?

@moonlighy: How did you find your love for this job?

@redbullanddepression: what the prettiest star in the sky in your opinion? also, you are a great role model as a queer woman who is attending university next year to major in aerospace engineering!!!

Morning Jeanette. My 10 year son old recently told me his dream job that he would love to do is to become an Astronaut or be apart of a team that builds a spaceship. What is your best suggestion for me as his parent to help expose him to know what life is like for an astronaut and how much work did you put in your education to help you solidify your career that I can use as encouragement for him? Thanks again and you're AWESOME.

I spent 11 and a half years in school after high school, so I tell this to students because it takes a lot of investment in educating yourself. Then even beyond that, gaining experiences that are meaningful. After graduate school, working at Ford Motor Company and the CIA really taught me how to be a detailed scientist as well as working operationally in the field. I also did internships to help hone and sharpen skills as an engineer. I was happy with my career, and then I applied.

What's something you didn't know about being an astronaut before you actually became one? Do you have any words of advice for young astronauts?

LIFTOFF!

On July 7, three crew members launched from Earth; headed to their new home on the International Space Station. 

Crewmembers Kate Rubins of NASA, Anatoly Ivanishin of Roscosmos and Takuya Onishi of the Japan Aerospace Exploration Agency (JAXA) will spend approximately four months on the orbital complex, returning to Earth in October.

Hail the Hexagon...

The full light of our sun allowed the Cassini spacecraft to capture this image of Saturn's hexagonal polar jet stream, but the sun does not provide much warmth. In addition to being low in the sky (just like summer at Earth's poles), the sun is nearly ten times as distant from Saturn as from Earth. This results in the sunlight being only about 1 percent as intense as at our planet. 

The view was obtained at a distance of approximately 560,000 miles (900,000 kilometers) from Saturn. Image scale is 33 miles (54 kilometers) per pixel.

Studying Sediments in Space

An International Space Station investigation called BCAT-CS studies dynamic forces between sediment particles that cluster together.

For the study, scientists sent mixtures of quartz and clay particles to the space station and subjected them to various levels of simulated gravity.

Conducting the experiment in microgravity makes it possible to separate out different forces that act on sediments and look at the function of each.

Sediment systems of quartz and clay occur many places on Earth, including rivers, lakes, and oceans, and affect many activities, from deep-sea hydrocarbon drilling to carbon sequestration.

Understanding how sediments behave has a range of applications on Earth, including predicting and mitigating erosion, improving water treatment, modeling the carbon cycle, sequestering contaminants and more accurately finding deep sea oil reservoirs.

It also may provide insight for future studies of the geology of new and unexplored planets.

5 Myths About Becoming a Flight Director

Have you ever wondered if you have what it takes to become a NASA Flight Director? 

They are historically well known for making difficult calls and guiding the crew through "Houston, we've had a problem" situations, but in all spaceflight operations, they are ultimately responsible for the success of the mission.

We're looking for a new class of Flight Directors to join our team, and there are a few things to know.

Here are a few myths about becoming a Flight Director:

MYTH: You have to have already been a flight controller in Mission Control at NASA to become a flight director.

FACT: Although many flight directors have previously been NASA flight controllers, that is not a prerequisite to apply. The necessary experience could come from the military, other spaceflight organizations or areas that operate in similar high-stakes conditions.

MYTH: You have to already have a special spaceship flying license to apply.

FACT: The only place to get certified is on the job at NASA. Once chosen, the new flight directors will receive training on flight control and vehicle systems, as well as operational leadership and risk management.

MYTH: All flight directors have advanced degrees like, a PhD.

FACT: While a Bachelor's degree in engineering, biological science, physical science, computer science or mathematics from an accredited university is necessary, an advanced degree is not required to become a flight director.

MYTH: Flight directors are required to have experience in the space industry.

FACT: While you need at least three years of related, progressively responsible professional experience to apply, it can come from a variety of industries as long as it represents time-critical decision-making experience in high-stress, high-risk environments.

MYTH: Only astronauts become flight directors and vice versa.

FACT: To date, only one astronaut, T.J. Creamer, has become a flight director, and no flight directors have become astronauts. However, members of the flight controller teams have become astronauts. The "capsule communicator," or CAPCOM, role in Mission Control is more often filled by astronauts because the CAPCOM is the one responsible for relaying the flight director's decisions to the astronauts in space.

Okay, but What are the requirements?

Basic Qualification Requirements

Applicants must meet the following minimum requirements before submitting an application:

Be a U.S. citizen.

Have a Bachelor's degree from an accredited institution in engineering, biological science, physical science, computer science or math.

Have at least three years of related, progressively responsible professional experience.

Applications for our next Flight Director class open on Dec. 3, 2021 and close Dec. 16, 2021! Visit: go.nasa.gov/FlightDirector

Discover NASA Technology in Your Life

Have you ever wondered how space exploration impacts you? “Spinoffs” are products and services developed from NASA technology or improved through NASA partnerships. These innovations—first created to help explore space and study Earth—are responsible for billions of dollars in both revenue and saved costs, tens of thousands of jobs created, and for changing the world around us.

Our NASA Home & City interactive web platform allows you to explore some of the spinoff technologies you can find in your everyday life, demonstrating the wider benefits of America’s investments in its space program.

Here are the seven most unexpected items you can find in your homes and cities which were “spun off” from technologies to enable the study and exploration of space.

1. Wireless Headsets

“That’s one small step for man, one giant leap for mankind.” On July 20, 1969, millions were glued to their television sets when NASA astronaut Neil Armstrong offered these famous words via live broadcast, upon becoming the first man to ever step foot on the Moon. This historic transmission was delivered from Armstrong’s headset to the headsets of Mission Control personnel at NASA, and then on to the world.

Improved by the technology that carried Neil Armstrong’s words, more compact and comfortable headsets were developed for airline pilots in the 1960s and '70s. Today those advancements continue to evolve in all forms of communications and telephone equipment. Mobile headsets provide greater efficiency and flexibility for everyone from professionals to video gamers.

2. Water Quality Monitoring

On the International Space Station very little goes to waste. This includes water, which is recovered from every possible source, cleaned and recycled.

Following our development of a simplified bacteria test for water quality on the space station, one engineer created a foundation to distribute test kits suitable for use in rural communities around the world. Water contamination is still a major problem in many places, and the test helps local communities and governments obtain and share water quality data using a smartphone app.

3. Skin Cream

We know that on Earth, gravity is a constant. For astronauts in orbit, however, it’s a different story—and according to a scientist at NASA's Johnson Space Center, studying what happens to bodies in microgravity “can lead to significant new discoveries in human biology for the benefit of humankind.”

As our researchers experimented with replicating microgravity conditions in the lab, they invented a bioreactor that could help simulate conditions that human cells experience in a space-like environment. This allowed them to perform tissue-growth experiments on the ground and in space, and eventually, to consider the question of how to protect human cells from the toxic effects of long-duration space missions.

Now, thanks to this NASA-patented bioreactor, one company uses agents from human cells that produce collagen to enrich its skin cream products. Lab tests have shown the rejuvenating cream to increase skin moisture content by 76 percent and reduce darkness and wrinkles by more than 50 percent.

4. Acoustic Guitars

From its start, NASA has innovated in all branches of aeronautics, which has led to numerous advances in helicopters, including ways to limit vibrations as they fly and advanced composites to build tougher, safer vehicles. 

An industrious helicopter manufacturer that built up its expertise with NASA contracts later used the same special vibration analysis equipment to enhance the sound of acoustic guitars. The company also built the body out of a fiberglass composite used for rotor blades. The resulting instruments are stronger and less expensive to produce than those of traditional rosewood and produce a rich, full sound.

5. Tiny [Mobile] Homes

While the International Space Station is the largest spacecraft ever flown—it's about the size of a football field—living and working space for astronauts is still at a premium. NASA created a studio called the Habitability Design Center to experiment with the interior design of spacecraft to maximize usable space and make scientific research as efficient and effective as possible.

An architect who helped NASA design the interior of the International Space Station launched a company specializing in compact trailers for camping and exploration. Suitable for a full hookup campsite or going completely off-grid, the company's flagship trailer can accommodate two adults and two children for sleeping and can be customized with a range of features including a shower, refrigerator, toilet, and more. And it all fits into a unit light enough to be towed by a four-cylinder car.

6. Blue Light Blocking Ski Goggles

Skiers and snowboarders face extremely bright sunlight, especially when it's reflected off the white snow. That can make it hard to see, and not just because of glare. The blue in sunlight makes it more difficult to discern colors at the edge of the visible light spectrum, like reds. A NASA-designed filter used in snow goggles helps block up to 95 percent of blue light, making it easier for people on the slopes to see the terrain clearly.

7. Implants for the Hearing Impaired

Hearing aids, which make sound louder, can only do so much for those who were born or have become deaf. Cochlear implants work in a completely different way, converting sound into digital signals that can be processed by the brain.  And the technology traces back in part to a NASA space shuttle engineer who used skills in electronics instrumentation and his own experiences with hearing loss to develop an early version of the life-changing device.

These are just a few examples of thousands of NASA Spinoff and dual-purpose technologies benefiting the world around us.
