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?

For scientists watching the Red Planet from our orbiters, the past month has been a windfall. "Global" dust storms, where a runaway series of storms create a dust cloud so large they envelop the planet, only appear every six to eight years (that’s 3-4 Mars years). Scientists still don't understand why or how exactly these storms form and evolve.

We launched our Spitzer Space Telescope into orbit around the Sunday on Aug. 25, 2003. Since then, the observatory has been lifting the veil on the wonders of the cosmos, from our own solar system to faraway galaxies, using infrared light.
Thanks to Spitzer, scientists were able to confirm the presence of seven rocky, Earth-size planets in the TRAPPIST-1 system. The telescope has also provided weather maps of hot, gaseous exoplanets and revealed a hidden ring around Saturn. It has illuminated hidden collections of dust in a wide variety of locations, including cosmic nebulas (clouds of gas and dust in space), where young stars form, and swirling galaxies. Spitzer has additionally investigated some of the universe's oldest galaxies and stared at the black hole at the center of the Milky Way.
In honor of Spitzer's Sweet 16 in space, here are 16 amazing images from the mission.
This Spitzer image shows the giant star Zeta Ophiuchi and the bow shock, or shock wave, in front of it. Visible only in infrared light, the bow shock is created by winds that flow from the star, making ripples in the surrounding dust.
The Pleiades star cluster, also known as the Seven Sisters, is a frequent target for night sky observers. This image from Spitzer zooms in on a few members of the sisterhood. The filaments surrounding the stars are dust, and the three colors represent different wavelengths of infrared light.
Newborn stars peek out from beneath their blanket of dust in this image of the Rho Ophiuchi nebula. Called "Rho Oph" by astronomers and located about 400 light-years from Earth, it's one of the closest star-forming regions to our own solar system.
The youngest stars in this image are surrounded by dusty disks of material from which the stars — and their potential planetary systems — are forming. More evolved stars, which have shed their natal material, are blue.
Located about 700 light-years from Earth, the eye-like Helix nebula is a planetary nebula, or the remains of a Sun-like star. When these stars run out of their internal fuel supply, their outer layers puff up to create the nebula. Our Sun will blossom into a planetary nebula when it dies in about 5 billion years.
The bright star at the center of this image is Eta Carinae, one of the most massive stars in the Milky Way galaxy. With around 100 times the mass of the Sun and at least 1 million times the brightness, Eta Carinae releases a tremendous outflow of energy that has eroded the surrounding nebula.
Located 28 million light-years from Earth, Messier 104 — also called the Sombrero galaxy or M104 — is notable for its nearly edge-on orientation as seen from our planet. Spitzer observations were the first to reveal the smooth, bright ring of dust (seen in red) circling the galaxy.
This infrared image of the galaxy Messier 81, or M81, reveals lanes of dust illuminated by active star formation throughout the galaxy's spiral arms. Located in the northern constellation of Ursa Major (which includes the Big Dipper), M81 is also about 12 million light-years from Earth.
Messier 82 — also known as the Cigar galaxy or M82 — is a hotbed of young, massive stars. In visible light, it appears as a diffuse bar of blue light, but in this infrared image, scientists can see huge red clouds of dust blown out into space by winds and radiation from those stars.
This image of Messier 101, also known as the Pinwheel Galaxy or M101, combines data in the infrared, visible, ultraviolet and X-rays from Spitzer and three other NASA space telescopes: Hubble, the Galaxy Evolution Explorer's Far Ultraviolet detector (GALEX) and the Chandra X-Ray Observatory. The galaxy is about 70% larger than our own Milky Way, with a diameter of about 170,000 light-years, and sits at a distance of 21 million light-years from Earth. Read more about its colors here.
Approximately 100 million years ago, a smaller galaxy plunged through the heart of the Cartwheel galaxy, creating ripples of brief star formation. As with the Pinwheel galaxy above, this composite image includes data from NASA's Spitzer, Hubble, GALEX and Chandra observatories.
The first ripple appears as a bright blue outer ring around the larger object, radiating ultraviolet light visible to GALEX. The clumps of pink along the outer blue ring are X-ray (observed by Chandra) and ultraviolet radiation.
Located 1,500 light-years from Earth, the Orion nebula is the brightest spot in the sword of the constellation Orion. Four massive stars, collectively called the Trapezium, appear as a yellow smudge near the image center. Visible and ultraviolet data from Hubble appear as swirls of green that indicate the presence of gas heated by intense ultraviolet radiation from the Trapezium's stars. Less-embedded stars appear as specks of green, and foreground stars as blue spots. Meanwhile, Spitzer's infrared view exposes carbon-rich molecules called polycyclic aromatic hydrocarbons, shown here as wisps of red and orange. Orange-yellow dots are infant stars deeply embedded in cocoons of dust and gas.
Located about 10,000 light-years from Earth in the constellation Auriga, the Spider nebula resides in the outer part of the Milky Way. Combining data from Spitzer and the Two Micron All Sky Survey (2MASS), the image shows green clouds of dust illuminated by star formation in the region.
This view of the North America nebula combines visible light collected by the Digitized Sky Survey with infrared light from NASA's Spitzer Space Telescope. Blue hues represent visible light, while infrared is displayed as red and green. Clusters of young stars (about 1 million years old) can be found throughout the image.
This infrared mosaic offers a stunning view of the Milky Way galaxy's busy center. The pictured region, located in the Sagittarius constellation, is 900 light-years agross and shows hundreds of thousands of mostly old stars amid clouds of glowing dust lit up by younger, more massive stars. Our Sun is located 26,000 light-years away in a more peaceful, spacious neighborhood, out in the galactic suburbs.
The Large Magellanic Cloud, a dwarf galaxy located about 160,000 light-years from Earth, looks like a choppy sea of dust in this infrared portrait. The blue color, seen most prominently in the central bar, represents starlight from older stars. The chaotic, bright regions outside this bar are filled with hot, massive stars buried in thick blankets of dust.
In this large celestial mosaic from Spitzer, there's a lot to see, including multiple clusters of stars born from the same dense clumps of gas and dust. The grand green-and-orange delta filling most of the image is a faraway nebula. The bright white region at its tip is illuminated by massive stars, and dust that has been heated by the stars' radiation creates the surrounding red glow.
Managed by our Jet Propulsion Laboratory in Pasadena, California, Spitzer's primary mission lasted five-and-a-half years and ended when it ran out of the liquid helium coolant necessary to operate two of its three instruments. But, its passive-cooling design has allowed part of its third instrument to continue operating for more than 10 additional years. The mission is scheduled to end on Jan. 30, 2020.

Do you know what the structural backbone is of our new rocket, the Space Launch System? If you answered the core stage, give yourself a double thumbs up! Or better yet, have astronaut Scott Kelly do it!
We’re on a journey to Mars. For bolder missions to deep space, we need a big, powerful rocket like SLS to take astronauts in the Orion spacecraft to places we've never gone before. The core stage is a major part of that story, as it will house the fuel and avionics systems that will power and guide the rocket to those new destinations beyond Earth’s orbit. Here's how:
It's Big, and It's Fast.
The core stage will be the largest rocket stage ever built and is under construction right now at our Michoud Assembly Facility in New Orleans. It will stand at 212 feet tall and weigh more than 2.3 million pounds with propellant. That propellant is cryogenic liquid hydrogen and liquid oxygen that will feed the vehicle’s RS-25 engines. In just 8.5 minutes, the core stage will reach Mach 23, which is faster than 17,000 mph!
It's Smart.
Similar to a car, the rocket needs all the equipment necessary for the "drive" to deep space. The core stage will house the vehicle’s avionics, including flight computers, instrumentation, batteries, power handling, sensors and other electronics. That's a lot of brain power behind those orange-clad aluminum walls. *Fun fact: Orange is the color of the rocket's insulation.
It's a Five-Parter.
The core stage is made up of five parts. Starting from the bottom is the engine section, which will deliver the propellants to the four RS-25 engines. It also will house avionics to steer the engines, and be an attachment point for the two, five-segment solid rocket boosters. The engine section for the first SLS flight has completed welding and is in the final phases of manufacturing at Michoud.
Next up is the liquid hydrogen tank. It will hold 537,000 gallons of liquid hydrogen cooled to -423 degrees Fahrenheit. Right now, engineers are building the tank for the first SLS mission. It will look very similar to the qualification test article that just finished welding at Michoud. That's an impressive piece of rocket hardware!
The next part of the core stage is the intertank, which will join the propellant tanks. It has to be super strong because it is the attachment point for the boosters and absorbs most of the force when they fire 3.6 million pounds of thrust each. It's also a "think tank" of sorts, as it holds the SLS avionics and electronics. The intertank is even getting its own test structure at our Marshall Space Flight Center in Huntsville, Alabama.
And then there's the liquid oxygen tank. It will store 196,000 gallons of liquid oxygen cooled to -297 degrees. If you haven't done the math, that's 733,000 gallons of propellant for both tanks, which is enough to fill 63 large tanker trucks. Toot, toot. Beep, beep! A confidence version of the tank has finished welding at Michoud, and it's impressive. Just ask this guy.
The topper of the core stage is the forward skirt. Funny name, but serious hardware. It's home to the flight computers, cameras and avionics. The avionics system is being tested right now in a half-ring structure at the Marshall Center.
You can click here for more SLS core stage facts. We'll continue building, and see you at the launch pad for the first flight of SLS with Orion in 2018!

The fantastical planets in Star Wars preceded our discovery of real planets outside our solar system…but fiction isn’t too far from the facts. When we send our spacecraft into the solar system and point our telescopes beyond, we often see things that seem taken right out of the Star Wars universe.
Saturn’s moon, Mimas, has become known as the "Death Star" moon because of how its 80-mile wide Herschel crater creates a resemblance to the Imperial battle station, especially when seen in this view from our Cassini spacecraft.
The most recently revealed exoplanet dubbed as Earth’s bigger, older cousin, Kepler-452b, might make a good stand-in for Coruscant — the high tech world seen in several Star Wars films whose surface is encased in a single, globe-spanning city. Kepler-452b belongs to a star system 1.5 billion years older than Earth’s! That would give any technologically adept species more than a billion-year jump ahead of us.
At 3,600 degrees Fahrenheit, CoRoT-7B is a HOT planet. Discovered in 2010 with France’s CoRoT satellite, it’s some 480 light-years away, and has a diameter 70% larger than Earth’s, with nearly five times the mass. Possibly the boiled-down remnant of a Saturn-sized planet, its orbit is so tight that its star looms much larger in its sky than our sun appears to us, keeping its sun-facing surface molten! This scorching planet orbiting close to its star could be a good analog for planet Mustafar from Star Wars.
Luke Skywalker’s home planet, Tatooine, is said to possess a harsh, desert environment, swept by sandstorms as it roasts under the glare of twin suns. Real exoplanets in the thrall of two or more suns are even harsher! Kepler-16b was the Kepler telescope’s first discovery of a planet in a “circumbinary” orbit (a.k.a, circling both stars, as opposed to just one, in a double star system). This planet, however, is likely cold, about the size of Saturn, and gaseous, though partly composed of rock.
Fictional Hoth is a frozen tundra that briefly serves as a base for the hidden Rebel Alliance. It’s also the nickname of real exoplanet OGLE-2005-BLG-390, a cold super-Earth whose surface temperature clocks in at minus 364 degrees Fahrenheit.
Kepler-22b, analog to the Star Wars planet Kamino…which was the birthplace of the army of clone soldiers, is a super-Earth that could be covered in a super ocean. The jury is still out on Kepler-22b’s true nature; at 2.4 times Earth’s radius, it might even be gaseous. But if the ocean world idea turns out to be right, we can envision a physically plausible Kamino-like planet.
Gas giants of all stripes populate the real exoplanet universe; in Star Wars, a gas giant called Bespin is home to a “Cloud City” actively involved in atmospheric mining. Mining the atmospheres of giant gas planets is a staple of science fiction. We too have examined the question, and found that gases such as helium-3 and hydrogen could theoretically be extracted from the atmospheres of Uranus and Neptune.
Endor, the forested realm of the Ewoks, orbits a gas giant. Exomoon detection is still in its infancy for scientists on Earth. However, a possible exomoon (a moon circling a distant planet) was observed in 2014 via microlensing. It will remain unconfirmed, however, since each microlensing event can be seen only once.

@barnabasthebarmy: How do you deal with being cooped up with other people for so long?
Hii! I'm unsure if you've been asked this before, but I'd like to give it a shot anyway. What's the greatest legacy you hope to leave to the future generations? Whether it's one of the things you've accomplished already or are hoping to accomplish yet. Thank you very much!
It's a long ways down. This is a view from the vantage point of astronaut Shane Kimbrough during his spacewalk last Friday outside the International Space Station. Shane posted this photo and wrote, " View of our spectacular planet (and my boots) during the #spacewalk yesterday with @Thom_astro." During the spacewalk with Kimbrough and Thomas Pesquet of ESA, which lasted just over six-and-a-half hours, the two astronauts successfully disconnected cables and electrical connections to prepare for its robotic move Sunday, March 26.
Two astronauts will venture outside the space station again this Thursday, March 30 for the second of three spacewalks. Kimbrough and Flight Engineer Peggy Whitson will begin spacewalk preparation live on NASA Television starting at 6:30 a.m. EST, with activities beginning around 8 a.m. Watch live online here.
