1. Rosetta’s Last Dance
The Rosetta mission was one of firsts: the first to orbit a comet and the first to dispatch a lander to a comet's surface. Rosetta transformed our understanding of these ancient wanderers, and this week, mission controllers will command the spacecraft to execute a series of maneuvers to bring it out of orbit around Comet 67P/Churyumov-Gerasimenko. Watch live on Sept. 30 from 6:15-8 a.m. EDT, the Rosetta mission's 12-year odyssey in space reaches its conclusion. Rosetta will descend to make a planned impact on the comet’s surface with its instruments recording science data during descent.

2. Hubble Spots Possible Water Plumes Erupting on Jupiter's Moon Europa
On Monday, Sept. 26, our scientists announced what may be water vapor plumes erupting off the surface of Jupiter's moon Europa, based on data from the Hubble Space Telescope. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.

3. Not So Impossible After All
Scientists have found an "impossible" ice cloud on Saturn's moon Titan. The puzzling appearance of an ice cloud prompted our researchers to suggest that a different process than previously thought could be forming clouds on Titan. The process may be similar to one seen over Earth's poles. Today, the Cassini spacecraft will perform a targeted Titan flyby, skimming just 1,079 miles (1,736 kilometers) above its hazy surface. Several of Cassini's instruments will be watching for clouds and other phenomena in the atmosphere, as well as taking measurements of the surface.

4. Lunar Intrigue
Earth's moon is a colorless world of grays and whites, right? Not really. As seen in these images from the Lunar Reconnaissance Orbiter, some landscapes on the moon reveal a whole range of color. One such place is the mountainous complex of ancient lava flows known as the Lassell Massif, one of the moon's so-called "red spots."

At NASA, we’re not immune to effects of climate change. The seas are rising at NASA coastal centers – the direct result of warming global temperatures caused by human activity. Several of our centers and facilities were built near the coast, where there aren’t as many neighbors, as a safety precaution. But now the tides have turned and as sea levels rise, these facilities are at greater risk of flooding and storms.
Global sea level is increasing every year by 3.3 millimeters, or just over an eighth of an inch, and the rate of rise is speeding up over time. The centers within range of rising waters are taking various approaches to protect against future damage.
Kennedy Space Center in Florida is the home of historic launchpad 39A, where Apollo astronauts first lifted off for their journey to the Moon. The launchpad is expected to flood periodically from now on.
Like Kennedy, Wallops Flight Facility on Wallops Island, Virginia has its launchpads and buildings within a few hundred feet of the Atlantic Ocean. Both locations have resorted to replenishing the beaches with sand as a natural barrier to the sea.
Native vegetation is planted to help hold the sand in place, but it needs to be replenished every few years.
At the Langley Research Center in Hampton, Virginia, instead of building up the ground, we’re hardening buildings and moving operations to less flood-prone elevations. The center is bounded by two rivers and the Chesapeake Bay.
The effects of sea level rise extend far beyond flooding during high tides. Higher seas can drive larger and more intense storm surges – the waves of water brought by tropical storms.
In 2017, Hurricane Harvey brought flooding to the astronaut training facility at Johnson Space Center in Houston, Texas. Now we have installed flood resistant doors, increased water intake systems, and raised guard shacks to prevent interruptions to operations, which include astronaut training and mission control.
Our only facility that sits below sea level already is Michoud Assembly Facility in New Orleans. Onsite pumping systems protected the 43-acre building, which has housed Saturn rockets and the Space Launch System, from Hurricane Katrina. Since then, we’ve reinforced the pumping system so it can now handle double the water capacity.
Ames Research Center in Silicon Valley is going one step farther and gradually relocating farther south and to several feet higher in elevation to avoid the rising waters of the San Francisco Bay.
Understanding how fast and where seas will rise is crucial to adapting our lives to our changing planet.
We have a long-standing history of tracking sea level rise, through satellites like the TOPEX-Poseidon and the Jason series, working alongside partner agencies from the United States and other countries.
We just launched the Sentinel-6 Michael Freilich satellite—a U.S.-European partnership—which will use electromagnetic signals bouncing off Earth’s surface to make some of the most accurate measurements of sea levels to date.

Some people watch scary movies because they like being startled. A bad guy jumps out from around a corner! A monster emerges from the shadows! Scientists experience surprises all the time, but they’re usually more excited than scared. Sometimes theories foreshadow new findings — like when there’s a dramatic swell in the movie soundtrack — but often, discoveries are truly unexpected.
Scientists working with the Fermi Gamma-Ray Space Telescope have been jumping to study mysterious bumps in the gamma rays for a decade now. Gamma rays are the highest-energy form of light. Invisible to human eyes, they’re created by some of the most powerful and unusual events and objects in the universe. In celebration of Halloween, here are a few creepy gamma-ray findings from Fermi’s catalog.
Stellar Graveyards
If you were to walk through a cemetery at night, you’d expect to trip over headstones or grave markers. Maybe you’d worry about running into a ghost. If you could explore the stellar gravesite created when a star explodes as a supernova, you’d find a cloud of debris expanding into interstellar space. Some of the chemical elements in that debris, like gold and platinum, go on to create new stars and planets! Fermi found that supernova remnants IC 443 and W44 also accelerate mysterious cosmic rays, high-energy particles moving at nearly the speed of light. As the shockwave of the supernova expands, particles escape its magnetic field and interact with non-cosmic-ray particles to produce gamma rays.
Ghost Particles
But the sources of cosmic rays aren’t the only particle mysteries Fermi studies. Just this July, Fermi teamed up with the IceCube Neutrino Observatory in Antarctica to discover the first source of neutrinos outside our galactic neighborhood. Neutrinos are particles that weigh almost nothing and rarely interact with anything. Around a trillion of them pass through you every second, ghost-like, without you noticing and then continue on their way. (But don’t worry, like a friendly ghost, they don’t harm you!) Fermi traced the neutrino IceCube detected back to a supermassive black hole in a distant galaxy. By the time it reached Earth, it had traveled for 3.7 billion years at almost the speed of light!
Black Widow Pulsars
Black widows and redbacks are species of spiders with a reputation for devouring their partners. Astronomers have discovered two types of star systems that behave in a similar way. Sometimes when a star explodes as a supernova, it collapses back into a rapidly spinning, incredibly dense star called a pulsar. If there’s a lighter star nearby, it can get stuck in a close orbit with the pulsar, which blasts it with gamma rays, magnetic fields and intense winds of energetic particles. All these combine to blow clouds of material off the low-mass star. Eventually, the pulsar can eat away at its companion entirely.
Dark Matter
What’s scarier than a good unsolved mystery? Dark matter is a little-understood substance that makes up most of the matter in the universe. The stuff that we can see — stars, people, haunted houses, candy — is made up of normal matter. But our surveys of the cosmos tell us there’s not enough normal matter to keep things working the way they do. There must be another type of matter out there holding everything together. One of Fermi’s jobs is to help scientists narrow down the search for dark matter. Last year, researchers noticed that most of the gamma rays coming from the Andromeda galaxy are confined to its center instead of being spread throughout. One possible explanation is that accumulated dark matter at the center of the galaxy is emitting gamma rays!
Fermi has helped us learn a lot about the gamma-ray universe over the last 10 years. Learn more about its accomplishments and the other mysteries it’s working to solve. What other surprises are waiting out among the stars?

As a child fascinated with aviation, Michael Jorgensen, Public Affairs Specialist for the Electrified Powertrain Flight Demonstration project, attended EAA AirVenture Oshkosh (“Oshkosh” for short) multiple times. Now, he represents us there, sharing what we’ve been working on. Read on to see what going to Oshkosh is like as Michael takes us on a tour—and join us next time!
MICHAEL:
Every year, Wittman Regional Airport in the town of Oshkosh, Wisconsin, swells from 67,000 to 600,000 people, becoming a hotspot for aviation in the United States. The Experimental Aircraft Association (EAA) began AirVenture in 1953 and is a ‘Must Do’ for any aviation geek.
My story with EAA AirVenture began in the late 1990s. As a fan of everything aviation, and having grown up near Chicago, Oshkosh was always on my radar – and I attended several times while I was growing up.

Coming back to the airport grounds this week, all my childhood memories came flooding back: the noises, the planes, the smells, and the pure excitement. As a kid, I could only dream of working for NASA, never imagining it would come true almost 25 years later.

When driving in, you first see a lot of air traffic – ranging from hang gliders, to old warbirds, to stunt planes, to the newest military jets rumbling skyward. During the last full week in July, the airport control tower becomes the busiest one in the world, coordinating approximately 116 takeoffs/landings per hour throughout each day – almost 2 every minute! Last year saw more than 10,000 aircraft arrive at the airport. The excitement grows as you pull off the highway and are greeted by rows and rows of general aviation aircraft as far as the eye can see.

The constant propeller buzz in the background and crackling of fighter jets overhead is noticeable as you walk through the airport grounds. What makes this sight even more unique is camping tents under the wings of each aircraft, stretching along the entire grounds of the airport. AirVenture truly is a summer camp for #AvGeeks.

The main tarmac at the airport is converted into Boeing Plaza, the central display area featuring the biggest and most exciting aircraft: C-17 Globetrotter III, SR-71 Blackbird, F-117 Nighthawk, DC-3, and many, many more. One year, I even got to see the Concorde fly into and out of this teeny regional airport in the middle of Wisconsin.
There are countless opportunities to interact with the pilots and other aviation enthusiasts including sitting in cockpits, checking out the interiors and exteriors of various airplanes, and chances to fly in vintage aircraft including an original 1929 Ford Trimotor and a B-17 Flying Fortress from 1945. And, of course, no matter my age, I posed with anything and everything I found interesting, including a T-38 Talon stationed in front of the NASA pavilion and the inside of an ecoDemonstrator.

This year’s theme for the NASA pavilion was “Faces of Flight”. Throughout the week, we had meet-and-greets with leaders, researchers, engineers, and even an astronaut or two, hands-on educational experiences for guests of all ages, giveaways, and models of our aircraft, spacecraft, and more, including a model of the Ingenuity Mars Helicopter and the Space Launch System rocket.
Aside from the events in the NASA pavilion, we participated in a number of panels like Women@NASA, where women leaders from the Aeronautics Research Mission Directorate talked about NASA’s aviation research portfolio, activities taking places at NASA centers, and their personal experiences as leaders.
If you’re interested in the future of aviation—supersonic flight, advanced air mobility, and so much more—come see us at Oshkosh!

Hey! I was wondering how everyone on the ISS adjusts to each other’s culture and language. It seems like it might be hard with language barriers and other factors, to live in a confined space with people from another country. Do others try to teach you their language? Does everyone mostly speak English, or do some people speak Russian?
What do you hope to find on the mars? / What would be the best possible outcome?
What exactly happens to the human body during spaceflight? The Twins Study, a 340-day investigation conducted by NASA’s Human Research Program , sought to find answers. Scientists had an opportunity to see how conditions on the International Space Station translated to changes in gene expression by comparing identical twin astronauts: Scott Kelly who spent close to a year in space and Mark Kelly who remained on Earth.
From high above the skies, for almost a year, astronaut Scott Kelly periodically collected his own blood specimens for researchers on the ground during his One-Year Mission aboard the Space Station. These biological specimens made their way down to Earth onboard two separate SpaceX Dragon vehicles. A little bit of Scott returned to Earth each time and was studied by scientists across the United States.
Totaling 183 samples from Scott and his brother, Mark, these vials helped scientists understand the changes Scott’s body underwent while spending a prolonged stay in low Earth orbit.
Because identical twins share the same genetic makeup, they are very similar on a molecular level. Twin studies provide a way for scientists to explore how our health is impacted by the environment around us.
A significant finding is the variability in gene expression, which reflects how a body reacts to its environment and will help inform how gene expression is related to health risks associated with spaceflight. While in space, researchers observed changes in the expression of Scott’s genes, with the majority returning to normal after six months on Earth. However, a small percentage of genes related to the immune system and DNA repair did not return to baseline after his return to Earth. Further, the results identified key genes to target for use in monitoring the health of future astronauts and potentially developing personalized countermeasures.
Another key finding is that Scott’s immune system responded appropriately in space. For example, the flu vaccine administered in space worked exactly as it does on Earth. A fully functioning immune system during long-duration space missions is critical to protecting astronaut health from opportunistic microbes in the spacecraft environment.
Studying protein pathways in Scott enabled researchers to look at fluid regulation and fluid shifts within his body. Shifts in fluid may contribute to vision problems in astronauts. Scientists found a specific protein associated with fluid regulation was elevated in Scott, compared with his brother Mark on Earth.
The telomeres in Scott’s white blood cells, which are biomarkers of aging at the end of chromosomes, were unexpectedly longer in space then shorter after his return to Earth with average telomere length returning to normal six months later. In contrast, his brother’s telomeres remained stable throughout the entire period. Because telomeres are important for cellular genomic stability, additional studies on telomere dynamics are planned for future one-year missions to see whether results are repeatable for long-duration missions.
Scott Kelly participated in a series of cognitive performance evaluations (such as mental alertness, spatial orientation, and recognition of emotions) administered through a battery of tests and surveys. Researchers found that during spaceflight, Scott’s cognitive function remained normal for the first half of his stay onboard the space station compared to the second half of his spaceflight and to his brother, Mark, on the ground. However, upon landing, Scott’s speed and accuracy decreased. Re-exposure to Earth’s gravity and the dynamic experience of landing may have affected the results.
In studying various measurements on Scott, researchers found that his body mass decreased during flight, likely due to controlled nutrition and extensive exercise. While on his mission, Scott consumed about 30% less calories than researchers anticipated. An increase in his folate serum (vitamin B-9), likely due to an increase of the vitamin in his pre-packaged meals, was also noted by researchers. This is bolstered by the telomeres study, which suggests that proper nutrition and exercise help astronauts maintain health while in space.
Within five months of being aboard the space station, researchers found an increase in the thickness of Scott’s arterial wall, which may have been caused by inflammation and oxidative stress during spaceflight. Whether this change is reversible is yet to be determined. They hope these results will help them understand the stresses that the human cardiovascular system undergoes during spaceflight.
In addition, the results from the Microbiome, Epigenomics, and Integrative Omics studies suggest a human body is capable of adapting to and recovering from the spaceflight environment on a molecular level.
The data from the Twins Study Investigation will be explored for years to come as researchers report some interesting, surprising, and assuring data on how the human body is able to adapt to the extreme environment of spaceflight. This study gave us the first integrated molecular view into genetic changes, and demonstrated the plasticity and robustness of a human body!
We will use the valuable data to ensure the safety and health of the men and women who go on to missions to the Moon and on to Mars.

In recent years of tracking weather activity and the like, have there been more 'anomolies' that have stuck out more than others? (I.E hurricanes, typhoons or cyclones that start out as small storms then become hurricane 4-5 storms in a matter of days-weeks) I think what you guys are doing is awesome and keep up the good work ~TKL
Sending humans to space, returning to the Moon, transforming aircraft, exploring the extraordinary every day: just a few things you are a part of as a NASA intern. Whether you have dreamed of working at the agency your whole life, or discovered a new interest, students at NASA have the opportunity to make real contributions to space exploration and flight. Want to know more? Here are five ways these internships can be rocket fuel for your career:
Imagine walking into a lab to work side-by-side with NASA scientists, engineers and researchers. As a NASA intern, that’s a daily reality. Mentors are full-time employees who guide and work with students throughout their internship. Space communications intern Nick Sia believes working with a mentor is what makes NASA’s internships different. “Working one-on-one has given me more opportunities to work on different projects,” he says. “It’s the best motivation to do great work.”
As a NASA intern, your work matters. Students are treated as employees, and their ideas are valued. Hands-on assignments allow interns to make real contributions to NASA research and gain experience. For example, Erin Rezich is working in our mobility lab to help design excavation hardware for planetary surfaces such as the Moon. “It’s an incredibly exciting project because these are problems that have to be solved to move planetary exploration forward,” she says.
Not only do interns improve their technical skills, but they are also building communication and leadership skills. This summer, students are taking part in a two-week immersive design challenge. Participants will design a Ram Air Turbine for NASA Glenn’s 1x1 Supersonic Wind Tunnel. “This design challenge is a unique opportunity to create a design from scratch, which could actually be implemented,” says Woodrow Funk, an electrical testing engineer intern. Projects such as this allow students to work independently, plan, organize and improve time management skills.
NASA also offers many opportunities for students pursuing a career outside of STEM fields. Departments such as human resources, administration, education and communications engage students with hands-on projects. These organizations provide support essential to NASA’s programs and missions. “I was excited that NASA offered opportunities that match my skill set,” says Molly Kearns, a digital media student working with Space Communications and Navigation. Kearns’ first summer at NASA confirmed her passion for graphic design. “What makes the experience so rewarding is seeing content that I created published on social media sites,” she says.
Students come to NASA from all over the nation to develop important skills matched to their career goals and expand the way they think about their work. Being surrounded by the best scientists, developers, engineers, mathematicians and communicators is inspiring. NASA’s network is one of graduate fellow Jamesa Stokes’ main motivations. “There are tons of smart and awesome people who work here,” says Stokes, “At the end of the day, they are willing to help anyone who comes and asks for it.”
