Tracking A Warming Arctic – From Underground To High In The Sky

How will the audio feed from Perseverance make its way back to Earth?

Good luck to your student! Reach for Mars!

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.

New Sun Science Stamps from the U.S. Postal Service

To start off the summer, the U.S. Postal Service issued a set of stamps showcasing views of the Sun from our Solar Dynamics Observatory!

Since its launch in 2010, the Solar Dynamics Observatory (or SDO) has kept up a near-constant watch on the Sun from its vantage point in orbit around Earth. SDO watches the Sun in more than 10 different types of light, including some that are absorbed by Earth’s atmosphere so can only be seen from space. These different types of light allow scientists to study different parts of the Sun – from its surface to its atmosphere – and better understand the solar activity that can affect our technology on Earth and in space.

The new set of stamps features 10 images from SDO. Most of these images are in extreme ultraviolet light, which is invisible to human eyes.

Let’s explore the science behind some of the stamps!

Coronal hole (May 2016)

The dark area capping the northern polar region of the Sun is a coronal hole, a magnetically open area on the Sun from which high-speed solar wind escapes into space. Such high-speed solar wind streams can spark magnificent auroral displays on Earth when they collide with our planet’s magnetic field.

Solar flare (August 2011)

The bright flash on the Sun’s upper right is a powerful solar flare. Solar flares are bursts of light and energy that can disturb the part of Earth’s atmosphere where GPS and radio signals travel.

Active Sun (October 2014)

This view highlights the many active regions dotting the Sun’s surface. Active regions are areas of intense and complex magnetic fields on the Sun – linked to sunspots – that are prone to erupting with solar flares or explosions of material called coronal mass ejections.

Plasma blast (August 2012)

These images show a burst of material from the Sun, called a coronal mass ejection. These eruptions of magnetized solar material can create space weather effects on Earth when they collide with our planet’s magnetosphere, or magnetic environment – including aurora, satellite disruptions, and, when extreme, even power outages.

Coronal loops (July 2012)

These images show evolving coronal loops across the limb and disk of the Sun. Just days after these images were taken, the Sun unleashed a powerful solar flare.

Coronal loops are often found over sunspots and active regions, which are areas of intense and complex magnetic fields on the Sun.

Sunspots (October 2014)

This view in visible light – the type of light we can see – shows a cluster of sunspots near the center of the Sun. Sunspots appear dark because they are relatively cool compared to surrounding material, a consequence of the way their extremely dense magnetic field prevents heated material from rising to the solar surface.

Photographing Planets with the Roman Space Telescope

Nearly 100 years ago, astronomer Bernard Lyot invented the coronagraph – a device that made it possible to recreate a total solar eclipse by blocking the Sun’s light. That helped scientists study the Sun’s corona, which is the outermost part of our star’s atmosphere that’s usually hidden by bright light from its surface.

Our Nancy Grace Roman Space Telescope, now under construction, will test out a much more advanced version of the same thing. Roman’s Coronagraph Instrument will use special masks to block the glare from host stars but allow the light from dimmer, orbiting planets to filter through. It will also have self-flexing mirrors that will measure and subtract starlight automatically.

This glare-blocking prowess is important because planets can be billions of times dimmer than their host stars! Roman’s high-tech shades will help us take pictures of planets we wouldn’t be able to photograph using any other current telescopes.

Other observatories mainly use this planet-hunting method, called direct imaging, from the ground to photograph huge, bright planets called “super-Jupiters” in infrared light. These worlds can be dozens of times more massive than Jupiter, and they’re so young that they glow brightly thanks to heat left over from their formation. That glow makes them detectable in infrared light.

Roman will take advanced planet-imaging tech to space to get even higher-quality pictures. And while it’s known for being an infrared telescope, Roman will actually photograph planets in visible light, like our eyes can see. That means it will be able to see smaller, older, colder worlds orbiting close to their host stars. Roman could even snap the first-ever image of a planet like Jupiter orbiting a star like our Sun.

Astronomers would ultimately like to take pictures of planets like Earth as part of the search for potentially habitable worlds. Roman’s direct imaging efforts will move us a giant leap in that direction!

And direct imaging is just one component of Roman’s planet-hunting plans. The mission will also use a light-bending method called microlensing to find other worlds, including rogue planets that wander the galaxy untethered to any stars. Scientists also expect Roman to discover 100,000 planets as they cross in front of their host stars!

Solar System: Things to Know This Week

Reaching out into space yields benefits on Earth. Many of these have practical applications — but there's something more than that. Call it inspiration, perhaps, what photographer Ansel Adams referred to as nature's "endless prospect of magic and wonder." 

Our ongoing exploration of the solar system has yielded more than a few magical images. Why not keep some of them close by to inspire your own explorations? This week, we offer 10 planetary photos suitable for wallpapers on your desktop or phone. Find many more in our galleries. These images were the result of audacious expeditions into deep space; as author Edward Abbey said, "May your trails be crooked, winding, lonesome, dangerous, leading to the most amazing view."

1. Martian Selfie

This self-portrait of NASA's Curiosity Mars rover shows the robotic geologist in the "Murray Buttes" area on lower Mount Sharp. Key features on the skyline of this panorama are the dark mesa called "M12" to the left of the rover's mast and pale, upper Mount Sharp to the right of the mast. The top of M12 stands about 23 feet (7 meters) above the base of the sloping piles of rocks just behind Curiosity. The scene combines approximately 60 images taken by the Mars Hand Lens Imager, or MAHLI, camera at the end of the rover's robotic arm. Most of the component images were taken on September 17, 2016.

2. The Colors of Pluto

NASA's New Horizons spacecraft captured this high-resolution, enhanced color view of Pluto on July 14, 2015. The image combines blue, red and infrared images taken by the Ralph/Multispectral Visual Imaging Camera (MVIC). Pluto's surface sports a remarkable range of subtle colors, enhanced in this view to a rainbow of pale blues, yellows, oranges, and deep reds. Many landforms have their own distinct colors, telling a complex geological and climatological story that scientists have only just begun to decode.

3. The Day the Earth Smiled

On July 19, 2013, in an event celebrated the world over, our Cassini spacecraft slipped into Saturn's shadow and turned to image the planet, seven of its moons, its inner rings — and, in the background, our home planet, Earth. This mosaic is special as it marks the third time our home planet was imaged from the outer solar system; the second time it was imaged by Cassini from Saturn's orbit, the first time ever that inhabitants of Earth were made aware in advance that their photo would be taken from such a great distance.

4. Looking Back

Before leaving the Pluto system forever, New Horizons turned back to see Pluto backlit by the sun. The small world's haze layer shows its blue color in this picture. The high-altitude haze is thought to be similar in nature to that seen at Saturn's moon Titan. The source of both hazes likely involves sunlight-initiated chemical reactions of nitrogen and methane, leading to relatively small, soot-like particles called tholins. This image was generated by combining information from blue, red and near-infrared images to closely replicate the color a human eye would perceive.

5. Catching Its Own Tail

A huge storm churning through the atmosphere in Saturn's northern hemisphere overtakes itself as it encircles the planet in this true-color view from Cassini. This picture, captured on February 25, 2011, was taken about 12 weeks after the storm began, and the clouds by this time had formed a tail that wrapped around the planet. The storm is a prodigious source of radio noise, which comes from lightning deep within the planet's atmosphere.

7. More Stormy Weather

Jupiter is still just as stormy today, as seen in this recent view from NASA's Juno spacecraft, when it soared directly over Jupiter's south pole on February 2, 2017, from an altitude of about 62,800 miles (101,000 kilometers) above the cloud tops. From this unique vantage point we see the terminator (where day meets night) cutting across the Jovian south polar region's restless, marbled atmosphere with the south pole itself approximately in the center of that border. This image was processed by citizen scientist John Landino. This enhanced color version highlights the bright high clouds and numerous meandering oval storms.

8. X-Ray Vision

X-rays stream off the sun in this image showing observations from by our Nuclear Spectroscopic Telescope Array, or NuSTAR, overlaid on a picture taken by our Solar Dynamics Observatory (SDO). The NuSTAR data, seen in green and blue, reveal solar high-energy emission. The high-energy X-rays come from gas heated to above 3 million degrees. The red channel represents ultraviolet light captured by SDO, and shows the presence of lower-temperature material in the solar atmosphere at 1 million degrees.

9. One Space Robot Photographs Another

This image from NASA's Mars Reconnaissance Orbiter shows Victoria crater, near the equator of Mars. The crater is approximately half a mile (800 meters) in diameter. It has a distinctive scalloped shape to its rim, caused by erosion and downhill movement of crater wall material. Since January 2004, the Mars Exploration Rover Opportunity has been operating in the region where Victoria crater is found. Five days before this image was taken in October 2006, Opportunity arrived at the rim of the crater after a drive of more than over 5 miles (9 kilometers). The rover can be seen in this image, as a dot at roughly the "ten o'clock" position along the rim of the crater. (You can zoom in on the full-resolution version here.)

10. Night Lights

Last, but far from least, is this remarkable new view of our home planet. Last week, we released new global maps of Earth at night, providing the clearest yet composite view of the patterns of human settlement across our planet. This composite image, one of three new full-hemisphere views, provides a view of the Americas at night from the NASA-NOAA Suomi-NPP satellite. The clouds and sun glint — added here for aesthetic effect — are derived from MODIS instrument land surface and cloud cover products.

Got a question about black holes? Let’s get to the bottom of these odd phenomena. Ask our black hole expert anything! 

Black holes are mystifying yet terrifying cosmic phenomena. Unfortunately, people have a lot of ideas about them that are more science fiction than science. Don’t worry! Our black hole expert, Jeremy Schnittman, will be answering your your questions in an Answer Time session on Wednesday, October 2 from 3pm - 4 pm ET here on NASA’s Tumblr! Make sure to ask your question now by visiting http://nasa.tumblr.com/ask!

Jeremy joined the Astrophysics Science Division at our Goddard Space Flight Center in 2010 following postdoctoral fellowships at the University of Maryland and Johns Hopkins University. His research interests include theoretical and computational modeling of black hole accretion flows, X-ray polarimetry, black hole binaries, gravitational wave sources, gravitational microlensing, dark matter annihilation, planetary dynamics, resonance dynamics and exoplanet atmospheres. He has been described as a "general-purpose astrophysics theorist," which he regards as quite a compliment. 

Fun Fact: The computer code Jeremy used to make the black hole animations we featured last week is called "Pandurata," after a species of black orchid from Sumatra. The name pays homage to the laser fusion lab at the University of Rochester where Jeremy worked as a high school student and wrote his first computer code, "Buttercup." All the simulation codes at the lab are named after flowers.

10 Questions About the 2017 Astronaut Class

We will select between eight and 14 new astronaut candidates from among a record-breaking applicant class of more than 18,300, almost three times the number of applications the agency received in 2012 for the recent astronaut class, and far surpassing the previous record of 8,000 in 1978.

The candidates will be announced at an event at our Johnson Space Center in Houston, Texas at 2 p.m. EDT on June 7. You can find more information on how to watch the announcement HERE.

1. What are the qualifications for becoming an astronaut?

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

Bachelor’s degree from an accredited institution in engineering, biological science, physical science, computer science or mathematics. 

Degree must be followed by at least 3 years of related, progressively responsible, professional experience or at least 1,000 hours of pilot-in-command time in jet aircraft

Ability to pass the NASA Astronaut physical.

For more information, visit: https://astronauts.nasa.gov/content/faq.htm

2. What have selections looked like in the past?

There have been 22 classes of astronauts selected from the original “Mercury Seven” in 1959 to the most recent 2017 class. Other notable classes include:

The fourth class in 1965 known as “The Scientists: because academic experience was favored over pilot skills. 

The eighth class in 1978 was a huge step forward for diversity, featuring the first female, African American and Asian American selections.

The 16th class in 1996 was the largest class yet with 44 members – 35 U.S. astronauts and 9 international astronauts. They were selected for the frequent Space Shuttle flights and the anticipated need for International Space Station crewmembers.

The 21st class in 2013 was the first class to have 50/50 gender split with 4 female members and 4 male members.

3. What vehicles will they fly in?

They could be assigned on any of four different spacecraft: the International Space Station, our Orion spacecraft for deep space exploration or one of two American-made commercial crew spacecraft currently in development – Boeing’s CST-199 Starliner or the SpaceX Crew Dragon.

4. Where will they go?

These astronauts will be part of expanded crews aboard the space station that will significantly increase the crew time available to conduct the important research and technology demonstrations that are advancing our knowledge for missions farther into space than humans have gone before, while also returning benefits to Earth. They will also be candidates for missions beyond the moon and into deep space aboard our Orion spacecraft on flights that help pave the way for missions to Mars.

5. What will their roles be?

After completing two years of general training, these astronaut candidates will be considered full astronauts, eligible to be assigned spaceflight missions. While they wait for their turn, they will be given duties within the Astronaut Office at Johnson Space Center. Technical duties can range from supporting current missions in roles such as CAPCOM in Mission Control, to advising on the development of future spacecraft.

6. What will their training look like?

The first two years of astronaut candidate training will focus on the basic skills astronauts need. They’ll practice for spacewalks in Johnson’s 60-foot deep swimming pool, the Neutral Buoyancy Lab, which requires SCUBA certification. They’ll also simulate bringing visiting spacecraft in for a berthing to the space station using its robotic arm, Canadarm2, master the ins and outs of space station system and learn Russian. 

And, whether they have previous experience piloting an aircraft of not, they’ll learn to fly our fleet of T-38s. In addition, they’ll perfect their expeditionary skills, such as leadership and fellowship, through activities like survival training and geology treks.

7.  What kinds of partners will they work with?

They will join a team that supports missions going on at many different NASA centers across the country, but they’ll also interact with commercial partners developing spaceflight hardware. In addition, they will work with our international partners around the globe: ESA (the European Space Agency, the Canadian Space Agency, the Japan Aerospace Exploration Agency and the Russian space agency, Roscosmos.

8. How does the selection process work?

All 18,353 of the applications submitted were reviewed by human resources experts to determine if they met the basic qualifications. Those that did were then each reviewed by a panel of about 50 people, made up primarily of current astronauts. Called the Astronaut Rating Panel, that group narrowed to applicants down to a few hundred of what they considered the most highly qualified individuals, whose references were then checked.

From that point, a smaller group called the Astronaut Selection Board brought in the top 120 applicants for an intense round of interviews and some initial medical screening tests. That group is further culled to the top 50 applicants afterward, who are brought back for a second round of interviews and additional screening. The final candidates are selected from that group.

9. How do they get notified?

Each applicant selected to become an astronaut receives a phone call from the head of the Flight Operations Directorate at our Johnson Space Center and the chief of the astronaut office. They’re asked to share the good news with only their immediate family until their selection has been officially announced.

10. How does the on boarding process work?

Astronaut candidates will report for duty at Johnson Space Center in August 2017, newly fitted flight suits in tow, and be sworn into civil service. Between their selection and their report for duty, they will make arrangements to leave their current positions and relocate with their family to Houston, Texas.

What’s Up for February 2016?

Five morning planets, Comet Catalina passes Polaris and icy Uranus and icy Vesta meet near Valentine’s Day.

February mornings (until Feb. 20) feature Mercury, Venus, Saturn, Mars and Jupiter. The last time this five-planet dawn lineup happened was in 2005. The planets are easy to distinguish when you use the moon as your guide. Details on viewing HERE.

If you miss all five planets this month, you’ll be able to see them again in August’s sunset sky.

Last month, Comet Catalina’s curved dust tail and straight ion tail were visible in binoculars and telescopes near two galaxies that are close to the handle of the Big Dipper. Early this month, the comet nears Polaris, the North Star. It should be visible all month long for northern hemisphere observers.

There will be more opportunities to photograph Comet Catalina paired with other objects this month. It passes the faint spiral galaxy IC 342 and a pretty planetary nebula named NGC 1501 between Feb. 10 – 29. For binocular viewers, the magnitude 6 comet pairs up with a pretty string of stars, known as Kemble’s Cascade, on Feb. 24.

Finally, through binoculars, you should be able to pick out Vesta and Uranus near one another this month. You can use the moon as a guide on Feb. 12, and the cornerstone and the corner stars of Pegasus all month long.

For more information about What’s Up in the February sky, watch our monthly video HERE.

Using All of Our Senses in Space

Today, we and the National Science Foundation (NSF) announced the detection of light and a high-energy cosmic particle that both came from near a black hole billions of trillions of miles from Earth. This discovery is a big step forward in the field of multimessenger astronomy.

But wait — what is multimessenger astronomy? And why is it a big deal?

People learn about different objects through their senses: sight, touch, taste, hearing and smell. Similarly, multimessenger astronomy allows us to study the same astronomical object or event through a variety of “messengers,” which include light of all wavelengths, cosmic ray particles, gravitational waves, and neutrinos — speedy tiny particles that weigh almost nothing and rarely interact with anything. By receiving and combining different pieces of information from these different messengers, we can learn much more about these objects and events than we would from just one.

Lights, Detector, Action!  

Much of what we know about the universe comes just from different wavelengths of light. We study the rotations of galaxies through radio waves and visible light, investigate the eating habits of black holes through X-rays and gamma rays, and peer into dusty star-forming regions through infrared light.

The Fermi Gamma-ray Space Telescope, which recently turned 10, studies the universe by detecting gamma rays — the highest-energy form of light. This allows us to investigate some of the most extreme objects in the universe.

Last fall, Fermi was involved in another multimessenger finding — the very first detection of light and gravitational waves from the same source, two merging neutron stars. In that instance, light and gravitational waves were the messengers that gave us a better understanding of the neutron stars and their explosive merger into a black hole.

Fermi has also advanced our understanding of blazars, which are galaxies with supermassive black holes at their centers. Black holes are famous for drawing material into them. But with blazars, some material near the black hole shoots outward in a pair of fast-moving jets. With blazars, one of those jets points directly at us!

Multimessenger Astronomy is Cool

Today’s announcement combines another pair of messengers. The IceCube Neutrino Observatory lies a mile under the ice in Antarctica and uses the ice itself to detect neutrinos. When IceCube caught a super-high-energy neutrino and traced its origin to a specific area of the sky, they alerted the astronomical community.

Fermi completes a scan of the entire sky about every three hours, monitoring thousands of blazars among all the bright gamma-ray sources it sees. For months it had observed a blazar producing more gamma rays than usual. Flaring is a common characteristic in blazars, so this did not attract special attention. But when the alert from IceCube came through about a neutrino coming from that same patch of sky, and the Fermi data were analyzed, this flare became a big deal!

IceCube, Fermi, and followup observations all link this neutrino to a blazar called TXS 0506+056. This event connects a neutrino to a supermassive black hole for the very first time.  

Why is this such a big deal? And why haven’t we done it before? Detecting a neutrino is hard since it doesn’t interact easily with matter and can travel unaffected great distances through the universe. Neutrinos are passing through you right now and you can’t even feel a thing!

The neat thing about this discovery — and multimessenger astronomy in general — is how much more we can learn by combining observations. This blazar/neutrino connection, for example, tells us that it was protons being accelerated by the blazar’s jet. Our study of blazars, neutrinos, and other objects and events in the universe will continue with many more exciting multimessenger discoveries to come in the future.

2000 vs Now: 15 Years of Humans on Space Station

Humans have been living in space aboard the International Space Station 24-7-365 since Nov. 2, 2000. That’s 15 Thanksgivings, New Years, and holiday seasons astronauts have spent away from their families. 15 years of constant support from Mission Control Houston. And 15 years of peaceful international living in space. 

In November 2000, many of us stuck on Earth wished we could join (at least temporarily) the Expedition 1 crew aboard the International Space Station. Floating effortlessly from module to module, looking down on Earth from a breathtaking height of 350 kilometers.... It's a dream come true for innumerable space lovers.

But be careful what you wish for! Living on the Space Station also means hard work, cramped quarters, and... what's that smell? Probably more outgassing from a scientific experiment or, worse yet, a crewmate.

To get a feel of how long ago that was, this is what the world looked like then vs. now:
