In March, Jupiter, it’s moons and moon shadows will all be visible in the sky. Find out when and where to look up:
Jupiter dominates the evening sky this month, rising at sunset and setting at dawn. On March 8, Jupiter reaches what is called “opposition”. Imagine that Jupiter and the sun are at opposite ends of a straight line, with the Earth in between. This brings Jupiter its closest to Earth, so it shines brighter and appears larger in telescopes.
On the nights of March 14 – 15, March 21 – 22 and March 29, two of Jupiter’s moons will cross the planet’s disk.
When the planet is at opposition and the sun shines on Jupiter’s moons, we can see the moon’s shadow crossing the planet. There are actually 11 of these double shadow transits in March!
The next six months will be awesome times for you to image Jupiter when it’s highest in the sky; near midnight now, and a little earlier each night through the late summer.
Even through the smallest telescopes or binoculars, you should be able to see the two prominent belts on each side of Jupiter’s equator made up of the four Galilean moons: Io, Europa Ganymede and Calisto. If you have a good enough view, you may even see Jupiter’s Red Spot!
Our Juno spacecraft will arrive at Jupiter on July 4th of this year and will go into orbit around the giant planet. Right now, the Juno mission science team is actively seeking amateur and professional images of the planet. These images are uploaded to a Juno website, and the public is invited to discuss points of interest in Jupiter’s atmosphere.
Locations will later be voted on and the favorites will be targets for JunoCam, the spacecraft’s imaging camera. Once JunoCam has taken the images, they’ll be posted online. Imaging participants can then process these raw mission images and re-upload them for others to view.

We’ve discovered thousands of exoplanets – planets beyond our solar system – so far. These worlds are mysterious, but observations from telescopes on the ground and in space help us understand what they might look like.
Take the planet 55 Cancri e, for instance. It’s relatively close, galactically speaking, at 41 light-years away. It’s a rocky planet, nearly two times bigger than Earth, that whips around its star every 18 hours (as opposed to the 365 days it takes our planet to orbit the Sun. Slacker).
The planet’s star, 55 Cancri, is slightly smaller than our Sun, but it’s 65 times closer than the Sun is to Earth. Imagine a massive sun on the horizon! Because 55 Cancri e is so close to its star, it’s tidally locked just like our Moon is to the Earth. One side is always bathed in daylight, the other is in perpetual darkness. It’s also hot. Really hot. So hot that silicate rocks would melt into a molten ocean of melted rock. IT’S COVERED IN AN OCEAN OF LAVA. So, it’s that hot (between 3,140 degrees and 2,420 degrees F).
Scientists think 55 Cancri e also may harbor a thick atmosphere that circulates heat from the dayside to the nightside. Silicate vapor in the atmosphere could condense into sparkling clouds on the cooler, darker nightside that would reflect the lava below. It’s also possible that it would rain sand on the nightside, but … sparkling skies!

Our Juno spacecraft will fly over Jupiter’s Great Red Spot on July 10 at 10:06 p.m. EDT. This will be humanity’s first up-close and personal view of the gas giant’s iconic 10,000-mile-wide storm, which has been monitored since 1830 and possibly existing for more than 350 years.
The data collection of the Great Red Spot is part of Juno’s sixth science flyby over Jupiter’s mysterious cloud tops. Perijove (the point at which an orbit comes closest to Jupiter’s center) will be July 10 at 9:55 p.m. EDT.
At the time of perijove, Juno will be about 2,200 miles above the planet’s cloud tops. Eleven minutes and 33 seconds later…Juno will have covered another 24,713 miles and will be directly above the coiling crimson cloud tops of the Great Red Spot. The spacecraft will pass about 5,600 miles above its clouds.
When will we see images from this flyby?
During the flyby, all eight of the spacecraft’s instruments will be turned on, as well as its imager, JunoCam. Because the spacecraft will be collecting data with its Microwave Radiometer (MWR), which measures radio waves from Jupiter’s deep atmosphere, we cannot downlink information during the pass. The MWR can tell us how much water there is and how material is moving far below the cloud tops.
During the pass, all data will be stored on-board…with a downlink planned afterwards. Once the downlink begins, engineering data from the spacecraft’s instruments will come to Earth first, followed by images from JunoCam.
The unprocessed, raw images will be located HERE, on approximately July 14. Follow @NASAJuno on Twitter for updates.
Did you know you can download and process these raw images?
We invite the public to act as a virtual imaging team…participating in key steps of the process, from identifying features of interest to sharing the finished images online. After JunoCam data arrives on Earth, members of the public can process the images to create color pictures. The public also helps determine which points on the planet will be photographed. Learn more about voting on JunoCam’s next target HERE.
JunoCam has four filters: red, green, blue and near-infrared. We get red, green and blue strips on one spacecraft rotation (the spacecraft rotation rate is 2 revolutions per minute) and the near-infrared strips on the second rotation. To get the final image product, the strips must be stitched together and the colors lined up.
Anything from cropping to color enhancing to collaging is fair game. Be creative!
Submit your images to Juno_outreach@jpl.nasa.gov to be featured on the Mission Juno website!

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.
JAXA’s HTV3, taken during Expedition 32
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.

What can you see from the space station? Can you see stars, the moon and sun, and Earth weather like lightening storms?
Does the eclipse affect airplanes at all? Would pilots have to wear special glasses, and would people inside the airplane be told not to look out of the windows?
I don’t believe it should directly impact airplanes. We are looking at how the eclipse will affect radio communications which airplanes use, but that’s something we’ll learn with the data we collect during this eclipse. Pilots will need to be careful as always to not look directly at the Sun. If you are a lucky passenger on one of the flights that will cross the eclipse, make sure to bring your eclipse viewing glasses as you will need them to look at the Sun safely https://eclipse2017.nasa.gov/safety That would be an amazing opportunity to view the eclipse from a plane as you wouldn’t have to worry about cloud cover. You may also get a longer viewing experience if you are following the path of totality! In fact, some NASA scientist are going to be flying experiments on a couple of NASA planes! https://youtu.be/R0GNqlGNZkI?list=PL_8hVmWnP_O2oVpjXjd_5De4EalioxAUi
Our solar system was built on impacts — some big, some small — some fast, some slow. This week, in honor of a possible newly-discovered large crater here on Earth, here’s a quick run through of some of the more intriguing impacts across our solar system.
Mercury does not have a thick atmosphere to protect it from space debris. The small planet is riddled with craters, but none as spectacular as the Caloris Basin. “Basin” is what geologists call craters larger than about 186 miles (300 kilometers) in diameter. Caloris is about 950 miles (1,525 kilometers) across and is ringed by mile-high mountains.
For scale, the state of Texas is 773 miles (1,244 kilometers) wide from east to west.
Venus’ ultra-thick atmosphere finishes off most meteors before they reach the surface. The planet’s volcanic history has erased many of its craters, but like almost any place with solid ground in our solar system, there are still impact scars to be found. Most of what we know of Venus’ craters comes from radar images provided by orbiting spacecraft, such as NASA’s Magellan.
Mead Crater is the largest known impact site on Venus. It is about 170 miles (275 kilometers) in diameter. The relatively-flat, brighter inner floor of the crater indicates it was filled with impact melt and/or lava.
Evidence of really big impacts — such as Arizona’s Meteor Crater — are harder to find on Earth. The impact history of our home world has largely been erased by weather and water or buried under lava, rock or ice. Nonetheless, we still find new giant craters occasionally.
A NASA glaciologist has discovered a possible impact crater buried under more than a mile of ice in northwest Greenland.
This follows the finding, announced in November 2018, of a 19-mile (31-kilometer) wide crater beneath Hiawatha Glacier – the first meteorite impact crater ever discovered under Earth’s ice sheets.
If the second crater, which has a width of over 22 miles (35 kilometers), is ultimately confirmed as the result of a meteorite impact, it will be the 22nd largest impact crater found on Earth.
Want to imagine what Earth might look like without its protective atmosphere, weather, water and other crater-erasing features? Look up at the Moon. The Moon’s pockmarked face offers what may be humanity’s most familiar view of impact craters.
One of the easiest to spot is Tycho, the tight circle and bright, radiating splat are easy slightly off center on the lower-left side of the full moon. Closer views of the 53-mile (85 kilometer)-wide crater from orbiting spacecraft reveal a beautiful central peak, topped with an intriguing boulder that would fill about half of a typical city block.
Mars has just enough atmosphere to ensure nail-biting spacecraft landings, but not enough to prevent regular hits from falling space rocks. This dark splat on the Martian south pole is less than a year old, having formed between July and September 2018. The two-toned blast pattern tells a geologic story. The larger, lighter-colored blast pattern could be the result of scouring by winds from the impact shockwave on ice. The darker-colored inner blast pattern is because the impactor penetrated the thin ice layer, blasting the dark sand underneath in all directions.
The bright spots in Ceres’ Occator crater intrigued the world from the moment the approaching Dawn spacecraft first photographed it in 2015. Closer inspection from orbit revealed the spots to be the most visible example of hundreds of bright, salty deposits that decorate the dwarf planet like a smattering of diamonds. The science behind these bright spots is even more compelling: they are mainly sodium carbonate and ammonium chloride that somehow made their way to the surface in a slushy brine from within or below the crust. Thanks to Dawn, scientists have a better sense of how these reflective areas formed and changed over time — processes indicative of an active, evolving world.
Scientists have long known we can learn a lot from impact craters — so, in 2005, they made one themselves and watched it happen.
On July 4, 2005, NASA’s Deep Impact spacecraft trained its instruments on an 816-pound (370-kilogram) copper impactor as it smashed into comet Tempel 1.
One of the more surprising findings: The comet has a loose, “fluffy” structure, held together by gravity and contains a surprising amount of organic compounds that are part of the basic building blocks of life.
Few Star Wars fans — us included — can resist Obi Wan Kenobi's memorable line “That’s no moon…” when images of Saturn’s moon Mimas pop up on a screen. Despite its Death Star-like appearance, Mimas is most definitely a moon. Our Cassini spacecraft checked, a lot — and the superlaser-looking depression is simply an 81-mile (130-kilometer) wide crater named for the moon’s discoverer, William Herschel.
The Welsh name of this crater on Jupiter’s ocean moon Europa looks like a tongue-twister, but it is easiest pronounced as “pool.” Pwyll is thought to be one of the youngest features we know of on Europa. The bright splat from the impact extends more than 600 miles (about 1,000 kilometers) around the crater, a fresh blanket over rugged, older terrain. “Fresh,” or young, is a relative term in geology; the crater and its rays are likely millions of years old.
Got a passion for Stickney, the dominant bowl-shaped crater on one end of Mars’ moon Phobos? Or a fondness for the sponge-like abundance of impacts on Saturn’s battered moon Hyperion (pictured)? There are countless craters to choose from. Share your favorites with us on Twitter, Instagram and Facebook.

No, that’s not the latest superhero spinoff movie - it’s an instrument launching soon from Antarctica! It’ll float on a giant balloon above 99.5% of the Earth’s atmosphere, measuring tiny particles called cosmic rays.
Right now, we have a team of several scientists and technicians from Washington University in St. Louis and NASA at McMurdo Station in Antarctica preparing for the launch of the Super Trans-Iron Galactic Element Recorder, which is called SuperTIGER for short. This is the second flight of this instrument, which last launched in Antarctica in 2012 and circled the continent for a record-breaking 55 days.
SuperTIGER measures cosmic rays, which are itty-bitty pieces of atoms that are zinging through space at super-fast speeds up to nearly the speed of light. In particular, it studies galactic cosmic rays, which means they come from somewhere in our Milky Way galaxy, outside of our solar system.
Most cosmic rays are just an individual proton, the basic positively-charged building block of matter. But a rarer type of cosmic ray is a whole nucleus (or core) of an atom - a bundle of positively-charged protons and non-charged neutrons - that allows us to identify what element the cosmic ray is. Those rare cosmic-ray nuclei (that’s the plural of nucleus) can help us understand what happened many trillions of miles away to create this particle and send it speeding our way.
The cosmic rays we’re most interested in measuring with SuperTIGER are from elements heavier than iron, like copper and silver. These particles are created in some of the most dynamic and exciting events in the universe - such as exploding and colliding stars.
In fact, we’re especially interested in the cosmic rays created in the collision of two neutron stars, just like the event earlier this year that we saw through both light and gravitational waves. Adding the information from cosmic rays opens another window on these events, helping us understand more about how the material in the galaxy is created.
While cosmic rays strike our planet harmlessly every day, most of them are blocked by the Earth’s atmosphere and magnetic field. That means that scientists have to get far above Earth - on a balloon or spacecraft - to measure an accurate sample of galactic cosmic rays. By flying on a balloon bigger than a football field, SuperTIGER can get to the edge of space to take these measurements.
It’ll float for weeks at over 120,000 feet, which is nearly four times higher than you might fly in a commercial airplane. At the end of the flight, the instrument will return safely to the ice on a huge parachute. The team can recover the payload from its landing site, bring it back to the United States, repair or make changes to it, if needed, and fly it again another year!
There are also cosmic ray instruments on our International Space Station, such as ISS-CREAM and CALET, which each started their development on a series of balloons launched from Antarctica. The SuperTIGER team hopes to eventually take measurements from space, too.
McMurdo Station is a hotspot for all sorts of science while it’s summer in the Southern Hemisphere (which is winter here in the United States), including scientific ballooning. The circular wind patterns around the pole usually keep the balloon from going out over the ocean, making it easier to land and recover the instrument later. And the 24-hour daylight in the Antarctic summer keeps the balloon at a nearly constant height to get very long flights - it would go up and down if it had to experience the temperature changes of day and night. All of that sunlight shining on the instrument's array of solar cells also gives a continuous source of electricity to power everything.
Antarctica is an especially good place to fly a cosmic ray instrument like SuperTIGER. The Earth’s magnetic field blocks fewer cosmic rays at the poles, meaning that we can measure more particles as SuperTIGER circles around the South Pole than we would at NASA scientific ballooning sites closer to the Earth’s equator.
The SuperTIGER team is hard at work preparing for launch right now - and their launch window opens soon! Follow @NASABlueshift for updates and opportunities to interact with our scientists on the ice.
