El Popocatépetl e Iztaccíhuatl . La leyenda de los volcanes es quizás uno de los relatos prehispánicos más difundidos en el Mexico actual. Cómo es de esperar, las versiones y detalles de esta historia varían (dependiendo el pueblo y región). Una de las más populares va así: Había una vez un Caudillo Tlaxcalteca que buscaba liberar a su pueblo del yugo mexica y en consecuencia decidió levantarse en armas. El Caudillo tenía una hija llamada Iztaccíhuatl, que era considerada la más hermosa de todas de las nobles tlaxcaltecas. Ella estaba enamorada del valeroso y noble guerrero Popocatépetl. El guerrero le pido al Caudillo por la mano de su hija y este aceptó con la condición de que volviera victorioso de la guerra . Sin embargo, un rival de Popocatépetl en un arranque de celos le dijo a la princesa que su amado había muerto en batalla. La princesa se agobió tanto que murió de tristeza. Popocatépetl volvió victorioso de la guerra y busca de su amada. Al enterarse de lo ocurrido una gran tristeza lo invadió, por lo que tomó el cuerpo de su amada y se la llevó a una montaña. Ahí, mientras custodiaba el sueño eterno de Iztaccíhuatl, los dioses y la nieve los transformaron en volcanes. Donde permanecen juntos hasta nuestros días. La leyenda de los volcanes ha inspirado a múltiples piezas de arte y literatura, por ejemplo el poema de Santos Chocano, cuyo fragmento más melancólico va así: Duerme en paz, Iztaccíhuatl nunca los tiempos borrarán los perfiles de tu expresión. Vela en paz, Popocatépetl: nunca los huracanes apagarán tu antorcha, eterna como el amor…Aportacion de corazón de Aztlán.

What’s It Like to Work in NASA’s Mission Control Center?

In the latest installment of our First Woman graphic novel series, we see Commander Callie Rodriguez embark on the next phase of her trailblazing journey, as she leaves the Moon to take the helm at Mission Control.

Flight directors work in Mission Control to oversee operations of the International Space Station and Artemis missions to the Moon. They have a unique, overarching perspective focused on integration between all the systems that make a mission a success – flight directors have to learn a little about a lot.

Diane Dailey and Chloe Mehring were selected as flight directors in 2021. They’ll be taking your questions about what it’s like to lead teams of flight controllers, engineers, and countless professionals, both agencywide and internationally, in an Answer Time session on Nov. 28, 2023, from noon to 1 p.m. EST (9-10 a.m. PST) here on our Tumblr!

Like Callie, how did their unique backgrounds and previous experience, prepare them for this role? What are they excited about as we return to the Moon?

🚨 Ask your questions now by visiting https://nasa.tumblr.com/ask.

Diane Dailey started her career at NASA in 2006 in the space station Environmental Control and Life Support Systems (ECLSS) group. As an ECLSS flight controller, she logged more than 1,700 hours of console time, supported 10 space shuttle missions, and led the ECLSS team. She transitioned to the Integration and System Engineering (ISE) group, where she was the lead flight controller for the 10th and 21st Commercial Resupply Services missions for SpaceX. In addition, she was the ISE lead for NASA’s SpaceX Demo-1 and Demo-2 crew spacecraft test flights. Dailey was also a capsule communicator (Capcom) controller and instructor.

She was selected as a flight director in 2021 and chose her call sign of “Horizon Flight” during her first shift in November of that year. She has since served as the Lead Flight director for the ISS Expedition 68, led the development of a contingency spacewalk, and led a spacewalk in June to install a new solar array on the space station. She is currently working on development of the upcoming Artemis II mission and the Human Lander Systems which will return humanity to the moon. Dailey was raised in Lubbock, Texas, and graduated from Texas A&M University in College Station with a bachelor’s degree in biomedical engineering. She is married and a mother of two. She enjoys cooking, traveling, and spending time outdoors.

Chloe Mehring started her NASA career in 2008 in the Flight Operations’ propulsion systems group and supported 11 space shuttle missions. She served as propulsion support officer for Exploration Flight Test-1, the first test flight of the Orion spacecraft that will be used for Artemis missions to the Moon. Mehring was also a lead NASA propulsion officer for SpaceX’s Crew Dragon spacecraft and served as backup lead for the Boeing Starliner spacecraft. She was accepted into the 2021 Flight Director class and worked her first shift in February 2022, taking on the call sign “Lion Flight”. Since becoming certified, she has worked over 100 shifts, lead the NG-17 cargo resupply mission team, and executed two United States spacewalks within 10 days of each other. She became certified as a Boeing Starliner Flight Director, sat console for the unmanned test flight in May 2022 (OFT-2) and will be leading the undock team for the first crewed mission on Starliner in the spring of next year. She originally is from Mifflinville, Pennsylvania, and graduated with a bachelor’s degree in aerospace engineering from The Pennsylvania State University in State College. She is a wife, a mom to one boy, and she enjoys fitness, cooking and gardening.

HBCU Students Make Moves with NASA Tech

In September 2023, students at HBCUs participated in a hackathon at the National HBCU Week Conference, where they used NASA’s technologies to create solutions to problems that affect Black communities. The winning team, Team Airtek, proposed a nano-sensor array for medical diagnoses that would give students on HBCU campuses a non-invasive, non-intensive way to test themselves for precursors for diseases and illnesses like diabetes and COVID.

The hackathon they participated in is a modified version of the full NASA Minority University Research and Education Project Innovation and Tech Transfer Idea Competition (MITTIC) that takes place each fall and spring semester at NASA’s Johnson Space Center in Houston.

No matter what you’re studying, you can join the MITTIC competition and come up with new and innovative tech to help your community and the world.

MITTIC could be the beginning of your career pathway: Teams can go on exclusive NASA tours and network with industry experts. Show off your entrepreneurial skills and your team could earn money—and bragging rights.

Don’t wait too long to apply or to share with someone who should apply! The deadline for proposals is Oct. 16, 2023. Apply here: https://microgravityuniversity.jsc.nasa.gov/nasamittic.

Roman's primary structure hangs from cables as it moves into the big clean room at NASA's Goddard Space Flight Center.

What Makes the Clean Room So Clean?

When you picture NASA’s most important creations, you probably think of a satellite, telescope, or maybe a rover. But what about the room they’re made in? Believe it or not, the room itself where these instruments are put together—a clean room—is pretty special.��

A clean room is a space that protects technology from contamination. This is especially important when sending very sensitive items into space that even small particles could interfere with.

There are two main categories of contamination that we have to keep away from our instruments. The first is particulate contamination, like dust. The second is molecular contamination, which is more like oil or grease. Both types affect a telescope’s image quality, as well as the time it takes to capture imagery. Having too many particles on our instruments is like looking through a dirty window. A clean room makes for clean science!

Two technicians clean the floor of Goddard’s big clean room.

Our Goddard Space Flight Center in Greenbelt, Maryland has the largest clean room of its kind in the world. It’s as tall as an eight-story building and as wide as two basketball courts.

Goddard’s clean room has fewer than 3,000 micron-size particles per cubic meter of air. If you lined up all those tiny particles, they’d be no longer than a sesame seed. If those particles were the size of 16-inch (0.4-meter) inflatable beach balls, we’d find only 3,000 spread throughout the whole body of Mount Everest!

A clean room technician observes a sample under a microscope.

The clean room keeps out particles larger than five microns across, just seven percent of the width of an average human hair. It does this via special filters that remove around 99.97% of particles 0.3 microns and larger from incoming air. Six fans the size of school buses spin to keep air flowing and pressurize the room. Since the pressure inside is higher, the clean air keeps unclean air out when doors open.

A technician analyzes a sample under ultraviolet light.

In addition, anyone who enters must wear a “bunny suit” to keep their body particles away from the machinery. A bunny suit covers most of the person inside. Sometimes scientists have trouble recognizing each other while in the suits, but they do get to know each other’s mannerisms very well.

This illustration depicts the anatomy of a bunny suit, which covers clean room technicians from head to toe to protect sensitive technology.

The bunny suit is only the beginning: before putting it on, team members undergo a preparation routine involving a hairnet and an air shower. Fun fact – you’re not allowed to wear products like perfume, lotion, or deodorant. Even odors can transfer easily!

Six of Goddard’s clean room technicians (left to right: Daniel DaCosta, Jill Bender, Anne Martino, Leon Bailey, Frank D’Annunzio, and Josh Thomas).

It takes a lot of specialists to run Goddard’s clean room. There are 10 people on the Contamination Control Technician Team, 30 people on the Clean Room Engineering Team to cover all Goddard missions, and another 10 people on the Facilities Team to monitor the clean room itself. They check on its temperature, humidity, and particle counts.

A technician rinses critical hardware with isopropyl alcohol and separates the particulate and isopropyl alcohol to leave the particles on a membrane for microscopic analysis.

Besides the standard mopping and vacuuming, the team uses tools such as isopropyl alcohol, acetone, wipes, swabs, white light, and ultraviolet light. Plus, they have a particle monitor that uses a laser to measure air particle count and size.

The team keeping the clean room spotless plays an integral role in the success of NASA’s missions. So, the next time you have to clean your bedroom, consider yourself lucky that the stakes aren’t so high!
