Known As The Horsehead Nebula – But You Can Call It Starbiscuit.

What is so special about the solar eclipse to you??

Huh, that’s a very good question and I probably answer it differently each time I get asked it. I love the fact that in totality you can see the solar atmosphere and get a chance to see the magnetic field structure of the Sun. This is something that you can’t normally do. I also love the idea that we’re going to be able to test a bunch of ionospheric models with the help of citizen scientist! This again is a very unique opportunity! But probably the thing that seems so special about this particular eclipse is seeing how excited everyone is about it! Most days I sit in my office working on my science (which I think is the best science and most interesting thing in the world- but I’m probably biased about that) and not too many other people in the world are all that excited about it. But with the eclipse, I get to share how cool this science is, and it’s amazing to see everyone get involved! 

How have you used the experience gained from Curiosity to make Perseverance better? Like, Curiosity's wheels are showing wear and tear, so is there something different about Perseverance's wheels?

New Glovebox Facility Heads to Space for Biological Research

The Japan Aerospace Exploration Agency H-IIB rocket is zooming toward the International Space Station carrying NASA’s Life Sciences Glovebox, a state-of-the-art microgravity research facility.

NASA's Marshall Space Flight Center in Huntsville, Alabama, and their partners around the world are excited to initiate new, high-value biological research in low-Earth orbit.

The Japanese rocket, hauling the research facility and other cargo via the HTV-7 transfer vehicle, successfully lifted off at 1:52 p.m. EDT from Tanegashima Space Center off the coast of Japan.

Its launch marks a first for hauling bulky equipment to space. Roughly the size of a large fish tank, the Life Sciences Glovebox comes in at 26 inches high, 35 inches wide and 24 inches deep, with 15 cubic feet of available workspace.

"The Life Sciences Glovebox is on its way to the space station to enable a host of biological and physiological studies, including new research into microgravity's long-term impact on the human body," said Yancy Young, project manager at Marshall. "This versatile facility not only will help us better protect human explorers on long voyages into deep space, but it could aid medical and scientific advances benefiting the whole world."

Boeing engineers at Marshall modified a refrigerator-freezer rack to house the core facility, using state-of-the-art, 3D-printing technology to custom design key pieces of the rack to secure the unit in its protective foam clamshell.

NASA is now determining the roster of science investigations lined up to make use of the facility, beginning as early as late 2018. "We've already got more than a dozen glovebox experiments scheduled in 2019, with many more to follow," said Chris Butler, payload integration manager for the glovebox at Marshall.

The Life Sciences Glovebox will be transferred to a zero-gravity stowage rack in the station's Kibo module, where up to two crew members can conduct experiments simultaneously, overseen in real-time by project researchers on Earth.

Applying Earth Observations Data to the Real World

In our DEVELOP Program, participants work on Earth science research projects and are mentored by science advisors from within the agency and from partner agencies, and extend research results to local communities. 

This year, our partners ran the gamut from NASA centers to The National Oceanic and Atmospheric Agency (NOAA) to the University of Georgia to state and local governments. The one thing all have in common: using data from our Earth-observing satellites to inform such topics as disaster relief, preserving watershed and marshlands, working municipalities to provide health and study. The program also helps future scientists develop research and presentation skills.

Annually, the participants gather at NASA Headquarters to present their findings. From more than two dozen, we’re highlighting a cross section whose projects covered climate and invasive species in Alaska; health and air quality in Las Cruces; disaster preparation in the Philippines; and air quality in the Shenandoah Valley.

The projects demonstrate to community leaders how our science measurements and predictions can be used to address local policy issues. This year, DEVELOP features more than two dozen projects covering Earth science topics from all corners of the globe. 

DEVELOP projects apply Earth observations to agriculture, climate, disasters, ecological forecasting, energy, health and air quality, oceans, water resources and weather. These projects highlight NASA Earth observation capabilities relative to environmental issues and concerns for enhanced policy and decision-making to improve life here on Earth.

NASA Spotlight: Christina Hernandez, NASA Mars 2020 Rover Instrument Engineer

“I was in love with the beauty of space. It was my introduction to appreciating the beauty of complex, chaotic things—black holes, giant gas planets, or killer asteroids—that got my imagination riled up.“ -Christina Hernandez

Christina Hernandez, a space enthusiast and self-proclaimed nerd, is an aerospace engineer at our Jet Propulsion Laboratory in California where she works as an instrument engineer on our newest rover mission – Mars2020. The Mars2020 rover is a robotic scientist that is launching to the Red Planet next year. If you would like to launch to the Red Planet as well, you can Send Your Name to Mars along with millions of other people! Christina’s job is to make sure that the instruments we send to the Martian surface are designed, built, tested and operated correctly so we can retrieve allll the science. When she isn’t building space robots, she loves exploring new hiking trails, reading science fiction and experimenting in the kitchen. Christina took a break from building our next Martian scientist to answer some questions about her life and her career: 

If you could go to Mars, would you? And what are three things you’d bring with you?

Only if I had a round trip ticket! I like the tacos and beach here on Earth too much. If I could go, I would bring a bag of Hot Cheetos, a Metallica album, and the book On the Shoulders of Giants.

If you could name the Mars2020 rover, what would you name it and why?

Pilas, a reference to a phrase my family says a lot, ponte las pilas. It literally means put your batteries on or in other words, get to work, look alive or put some energy into it. Our rover is going to need to have her batteries up and running for all the science she is going to be doing! Luckily, the rover has a radioisotope thermoelectric generator (RTG) to help keep the batteries charged!

What’s been your most memorable day at NASA?

It’s been seeing three of the instruments I worked on getting bolted and connected to the flight rover. I’ll never forget seeing the first 1’s and 0’s being exchanged between the rover compute element (RCE), the rover’s on-board brain, and the instruments’ electronics boxes (their brains). I am sure it was a wonderful conversation between the two!

It’s a long journey to get from Earth to Mars. What would be on your ultimate road trip playlist?

Metallica, The Cure, Queen, Echo and the Bunnymen, Frank Sinatra, Ramon Ayala, AC/DC, Selena, Los Angeles Azules, ughhhh – I think I just need a Spotify subscription to Mars.

What is one piece of advice you wish someone would’ve told you?

Take your ego out of the solution space when problem solving.

Do you have any secret skills, talents, or hobbies?

I love reading. Each year I read a minimum of 20 books, with my goal this year being 30 books. It’s funny I increased my goal during what has definitely been my busiest year at work. I recently got into watercolor painting. After spending so much time connected at work, I started looking for more analog hobbies. I am a terrible painter right now, but I painted my first painting the other day. It was of two nebulas! It’s not too bad! I am hoping watercolor can help connect me more to the color complexities of nature...and it’s fun!

What’s a project or problem that you would love the ability to tackle/work on?

I would love to work on designs for planetary human explorers. So far, I have focused on robotic explore, but when you throw a “loveable, warm, squishy thing” into the loop, its creates a different dimension to design – both with respect to operability and risk.

Thanks so much Christina! The Mars2020 rover is planned to launch on July 17, 2020, and touch down in Jezero crater on Mars on February 18, 2021.

Scary Space Stories to Tell in the Dark

The universe is full of dazzling sights, but there’s an eerie side of space, too. Nestled between the stars, shadowy figures lurk unseen. The entire galaxy could even be considered a graveyard, full of long-dead stars. And it’s not just the Milky Way – the whole universe is a bit like one giant haunted house! Our Nancy Grace Roman Space Telescope will illuminate all kinds of spine-chilling cosmic mysteries when it launches in 2027, but for now settle in for some true, scary space stories.

Flickering Lights

One of the first signs that things are about to get creepy in a scary movie is when the lights start to flicker. That happens all the time in space, too! But instead of being a sinister omen, it can help us find planets circling other stars.

Roman will stare toward the heart of our galaxy and watch to see when pairs of stars appear to align in the sky. When that happens, the nearer star – and orbiting planets – can lens light from the farther star, creating a brief brightening. That’s because every massive object warps the fabric of space-time, changing the path light takes when it passes close by. Roman could find around 1,000 planets using this technique, which is called microlensing.

The mission will also see little flickers when planets cross in front of their host star as they orbit and temporarily dim the light we receive from the star. Roman could find an additional 100,000 planets this way!

Galactic Ghosts

Roman is going to be one of the best ghost hunters in the galaxy! Since microlensing relies on an object’s gravity, not its light, it can find all kinds of invisible specters drifting through the Milky Way. That includes rogue planets, which roam the galaxy alone instead of orbiting a star…

…and solo stellar-mass black holes, which we can usually only find when they have a visible companion, like a star. Astronomers think there should be 100 million of these black holes in our galaxy.

Stellar Skeletons

Black holes aren’t the only dead stars hiding in the sky. When stars that aren’t quite massive enough to form black holes run out of fuel, they blast away their outer layers and become neutron stars. These stellar cores are the densest material we can directly observe. One sugar cube of neutron star material would weigh about 1 billion tons (or 1 trillion kilograms) on Earth! Roman will be able to detect when these extreme objects collide.

Smaller stars like our Sun have less dramatic fates. After they run out of fuel, they swell up and shrug off their outer layers until only a small, hot core called a white dwarf remains. Those outer layers may be recycled into later generations of stars and planets. Roman will explore regions where new stars are bursting to life, possibly containing the remnants of such dead stars.

Cosmic Cobwebs

If we zoom out far enough, the structure of space looks like a giant cobweb! The cosmic web is the large-scale backbone of the universe, made up mainly of a mysterious substance known as dark matter and laced with gas, upon which galaxies are built. Roman will find precise distances for more than 10 million galaxies to map the structure of the cosmos, helping astronomers figure out why the expansion of the universe is speeding up.

September 2017 Was 🔥 on the Sun

The Sun started September 2017 with flair, emitting 31 sizable solar flares and releasing several powerful coronal mass ejections, or CMEs, between Sept. 6-10.

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel. 

CMEs are massive clouds of solar material and magnetic fields that erupt from the Sun at incredible speeds. Depending on the direction they’re traveling in, CMEs can spark powerful geomagnetic storms in Earth’s magnetic field.

As always, we and our partners had many missions observing the Sun from both Earth and space, enabling scientists to study these events from multiple perspectives. With this integrated picture of solar activity, scientists can better track the evolution of solar eruptions and work toward improving our understanding of space weather.

The National Oceanic and Atmospheric Administration (NOAA)’s Geostationary Operational Environmental Satellite-16, or GOES-16, watches the Sun’s upper atmosphere — called the corona — at six different wavelengths, allowing it to observe a wide range of solar phenomena. GOES-16 caught this footage of an X9.3 flare on Sept. 6, 2017. 

This was the most intense flare recorded during the current 11-year solar cycle. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, and so on. GOES also detected solar energetic particles associated with this activity.

Our Solar Dynamics Observatory captured these images of X2.2 and X9.3 flares on Sept. 6, 2017, in a wavelength of extreme ultraviolet light that shows solar material heated to over one million degrees Fahrenheit.

JAXA/NASA’s Hinode caught this video of an X8.2 flare on Sept. 10, 2017, the second largest flare of this solar cycle, with its X-ray Telescope. The instrument captures X-ray images of the corona to help scientists link changes in the Sun’s magnetic field to explosive solar events like this flare.

Key instruments aboard our Solar and Terrestrial Relations Observatory, or STEREO, include a pair of coronagraphs — instruments that use a metal disk called an occulting disk to study the corona. The occulting disk blocks the Sun’s bright light, making it possible to discern the detailed features of the Sun’s outer atmosphere and track coronal mass ejections as they erupt from the Sun.

On Sept. 9, 2017, STEREO watched a CME erupt from the Sun. The next day, STEREO observed an even bigger CME. The Sept. 10 CME traveled away from the Sun at calculated speeds as high as 7 million mph, and was one of the fastest CMEs ever recorded. The CME was not Earth-directed: It side-swiped Earth’s magnetic field, and therefore did not cause significant geomagnetic activity. Mercury is in view as the bright white dot moving leftwards in the frame.

Like STEREO, ESA/NASA’s Solar and Heliospheric Observatory, or SOHO, uses a coronagraph to track solar storms. SOHO also observed the CMEs that occurred during Sept. 9-10, 2017; multiple views provide more information for space weather models. As the CME expands beyond SOHO’s field of view, a flurry of what looks like snow floods the frame. These are high-energy particles flung out ahead of the CME at near-light speeds that struck SOHO’s imager.

Our Interface Region Imaging Spectrometer, or IRIS, captured this video on Sept. 10, 2017, showing jets of solar material swimming down toward the Sun’s surface. These structures are sometimes observed in the corona during solar flares, and this particular set was associated with the X8.2 flare of the same day.  

Our Solar Radiation and Climate Experiment, or SORCE, collected the above data on total solar irradiance, the total amount of the Sun’s radiant energy, throughout Sept. 2017. While the Sun produced high levels of extreme ultraviolet light, SORCE actually detected a dip in total irradiance during the month’s intense solar activity. 

A possible explanation for this observation is that over the active regions — where solar flares originate — the darkening effect of sunspots is greater than the brightening effect of the flare’s extreme ultraviolet emissions. As a result, the total solar irradiance suddenly dropped during the flare events. 

Scientists gather long-term solar irradiance data in order to understand not only our dynamic star, but also its relationship to Earth’s environment and climate. We are ready to launch the Total Spectral solar Irradiance Sensor-1, or TSIS-1, this December to continue making total solar irradiance measurements.

The intense solar activity also sparked global aurora on Mars more than 25 times brighter than any previously seen by NASA’s Mars Atmosphere and Volatile Evolution, or MAVEN, mission. MAVEN studies the Martian atmosphere’s interaction with the solar wind, the constant flow of charged particles from the Sun. These images from MAVEN’s Imaging Ultraviolet Spectrograph show the appearance of bright aurora on Mars during the September solar storm. The purple-white colors show the intensity of ultraviolet light on Mars’ night side before (left) and during (right) the event.
