Space-Grown Crystals May Lead to More Efficient Drug Development

The International Space Station is a perfect environment for creating protein crystal structures for research.

In microgravity, protein molecules form more orderly, high-quality crystals. Studying these structures helps scientists understand their function and contributes to development of more effective treatments for diseases.

Experiments often need more than one try to generate ideal crystals, though. Researchers may have to return samples to Earth for analysis and then try again on a later mission on the space station.

Scientists are testing new methods of growing crystals that allow crew members to observe imperfections, make real-time adjustments, and try growing them again right away. This dramatically reduces the time and cost of conducting experiments aboard the space station and opens up the orbiting lab to more users. More efficient use of time and resources can produce research results in less time and lead to development of better drugs sooner.

You’ve seen things floating in space, but why does that happen and how does it affect science being conducted aboard the International Space Station?

Sure, floating looks like fun, but it could also unlock new scientific discoveries!

Microgravity makes the International Space Station the perfect place to perform research that is changing the lives of people on Earth, and preparing us to go deeper into space. This season on our series NASA Explorers, we are following science into low-Earth orbit and seeing what it takes to do research aboard the space station.

Spot the International Space Station

Right now, there are humans living and working off the Earth on the International Space Station. They orbit our planet from 250 miles above every 90 minutes, which means the crew sees 16 sunrises and sunsets every day.

If you’re in the right place, at the right time, the space station is visible to the naked eye. It looks like a fast-moving plane, only much higher and traveling thousands of miles an hour faster. The fact that it’s the third brightest object in the sky makes it easier to spot…if you know when to look up.

That’s where we can help! Our Spot the Station site allows you to enter your location and find out when the space station will be flying overhead. You can even sign up to receive alerts that will send you email or text messages to let you know when and where to look up.

Why is the space station visible? It reflects the light of the Sun, the same reason we can see the Moon. However, unlike the Moon, the space station isn’t bright enough to see during the day.

Did you have mentors that helped you?

In Roman mythology, the god Jupiter drew a veil of clouds around himself to hide his mischief. It was only Jupiter's wife, the goddess Juno, who could peer through the clouds and reveal Jupiter's true nature. ⁣ ⁣ Our @NASAJuno spacecraft is looking beneath the clouds of the massive gas giant, not seeking signs of misbehavior, but helping us to understand the planet's structure and history...⁣ ⁣ Now, @NASAJuno just published its first findings on the amount of water in the gas giant’s atmosphere. The Juno results estimate that at the equator, water makes up about 0.25% of the molecules in Jupiter's atmosphere — almost three times that of the Sun. An accurate total estimate of this water is critical to solving the mystery of how our solar system formed. 

The JunoCam imager aboard Juno captured this image of Jupiter's southern equatorial region on Sept. 1, 2017. The bottom image is oriented so Jupiter's poles (not visible) run left-to-right of frame.

Sixteen Images for Spitzer's Sweet 16! 🎂

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.

Giant Star Makes Waves

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 Seven Sisters Pose for Spitzer

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.

Young Stars in Their Baby Blanket of Dust

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.

The Infrared Helix

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 Tortured Clouds of Eta Carinae

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.

Spitzer Spies Spectacular Sombrero

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.

Spiral Galaxy Messier 81

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.

Spitzer Reveals Stellar Smoke

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.

A Pinwheel Galaxy Rainbow

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.

Cartwheel Galaxy Makes Waves

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.

Spitzer and Hubble Create Colorful Masterpiece

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.

A Space Spider Watches Over Young Stars

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.

North America Nebula in Different Lights

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.

Spitzer Captures Our Galaxy's Bustling Center

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 Eternal Life of Stardust

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.

A Stellar Family Portrait

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.

Take a good look: this is the black hole at the center of our galaxy.

In the inset image, gas in the glowing orange ring surrounds the black hole's event horizon, a boundary from which nothing can escape. The ring is created by light bending in the intense gravity around Sagittarius A*, which has a mass some four million times greater than our Sun. This groundbreaking image of Sagittarius A* was taken by the Event Horizon Telescope team with data from telescopes around the world. After the EHT's iconic image of M87*, released in 2019, this is only the second time a supermassive black hole has been directly observed with its shadow.

The wider look at the space around Sagittarius A* includes data contributed by several NASA missions. The orange specks and purple tendrils were captured in infrared light by the Hubble Space Telescope, and the blue clouds represent data from our orbiting Chandra X-ray Observatory.

Solar System: 5 Things To Know This Week

Our solar system is huge, so let us break it down for you. Here are 5 things you should know this week: 

1. From Pluto, with Love

Last Valentine’s Day, no one had even seen Pluto’s most famous feature, the heart-shaped Sputnik Planum. These days, the New Horizons spacecraft is sending more and more pictures back to Earth from its Pluto flyby last July. We received new ones almost on a weekly basis. For the latest love from the outer solar system, go HERE.

2. Saturn’s Rings: More (and Less) than Meets the Eye

The Cassini spacecraft is executing a series of maneuvers to raise its orbit above the plane of Saturn’s famous rings. This will offer some breathtaking views that you won’t want to miss. Meanwhile, Cassini scientists are learning surprising things, such as the fact that the most opaque sections of the rings are not necessarily the thickest.

3. Stay on Target

The Juno spacecraft recently completed a course correction maneuver to fine-tune its approach to Jupiter. After years of flight and millions of miles crossed, arrival time is now set to the minute: July 4th at 11:18 p.m. EST. See why we’re going to jupiter HERE.

4. The Many Lives of “Planet X”

The announcement of a potential new planet beyond Neptune creates an opportunity to look back at the ongoing search for new worlds in the unmapped reaches of our own solar system. Review what we’ve found so far, and what else might be out there HERE.

5. Answering the Call of Europa

There are a few places more intriguing that Jupiter’s icy moon, Europa, home to an underground ocean with all the ingredients necessary for potential life. We’re undertaking a new mission to investigate, and the project’s top manager and scientist will be giving a live lecture to detail their plans. Join Barry Goldstein and Bob Pappalardo on Feb. 11 at 10 p.m. EST for a live lecture series on Ustream.

6 Reasons NOAA’s GOES-R Satellite Matters

NOAA’s GOES-R weather satellite will soon be launched into space – becoming our nation’s most advanced geostationary satellite to date. So what does that mean for you? Here are six reasons to be excited about GOES-R:

1. GOES-R helps you know what the weather is going to be

Perhaps you turn on the TV or radio, or check your favorite weather website or smartphone weather app to get the latest forecast. No matter the platform of your weather forecast, the data and information for those forecasts come from NOAA’s National Weather Service (NWS).

Weather satellites, like the GOES satellites, are the backbone of NWS forecasts. GOES-R will be more advanced than any other weather satellite of its kind and could make the answer to the question “What’s the weather going to be?” more detailed and accurate both in the near term and further out into the future.

2. GOES-R will get better data faster than ever before

Do you live in an inland state, a state with a coastline or a state with a mountain range? Great, that’s all of you! Data from the GOES-R satellite will be a game changer for forecasters in your area.

Here’s why: satellites are fitted with instruments that observe weather and collect measurements. The primary instrument on the new GOES-R satellite will collect three times more data and provide four times better resolution and more than five times faster coverage than current satellites! This means the satellite can scan Earth’s Western Hemisphere every five minutes and as often as every 30 seconds in areas where severe weather forms, as compared to approximately every 30 minutes with the current GOES satellites. Pretty cool, right?

3. GOES-R is a real life-saver

This expedited data means that forecasts will be timelier, with more “real-time” information in them, allowing NWS to make those warnings and alerts that much faster, thereby potentially saving lives.

And a faster forecast is a big deal for our economy. Commercial shipping and aviation are just two examples of industries that rely on up-to-date weather data for critical decisions about how to route ships and safely divert planes around storms.

4. GOES-R helps keep the electricity flowing

We all depend on a power grid for virtually every aspect of modern life. But power grids are vulnerable to bursts of energy from the sun that can affect us on Earth. 

Luckily, GOES-R will be sitting over 22,000 miles above us, and in addition to measuring weather on Earth, it will monitor incoming space weather.

5. GOES-R is truly revolutionary

How different will GOES-R be? Imagine going from your classic black and white TV to a new high definition one. It will enable NOAA to gather data using three times more channels, four times the resolution, five times faster than the current GOES satellites. 

This faster, more accurate data means better observations of developing storms and other severe weather.

6. GOES-R will be a continuing a legacy

GOES-R may be the first of its kind, but it is the heir to a rich tradition of geostationary earth observation. 

In fact, NOAA has continuously operated a GOES satellite for over 40 years. Since 1975, GOES satellites have taken well over 3 million images!

The GOES-R satellite is scheduled to launch Saturday, Nov. 19 at 5:42 p.m. EST aboard a United Launch Alliance Atlas V rocket. Liftoff will occur from our Kennedy Space Center in Florida.
