Solar System: Things to Know This Week

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

1. The Lure of the Rings

Scientists and stargazers alike can’t resist the call of Saturn’s rings, or of its moon Titan. Both have been under close scrutiny by the Cassini spacecraft lately, and there are striking new pictures to prove it. Check out the latest images HERE.

2. A New Moon Rises

The Lunar Reconnaissance Orbiter has captured dramatic landscapes on the moon for more than six years. “A New Moon Rises,” now on display at the Smithsonian National Air and Space Museum in Washington, DC, showcases those images ranging from Apollo landing sites to mountains that rise out of the darkness of the lunar poles. See an online version of the exhibit HERE.  

3. Around the (Giant) World in (Just Under) 88 Days

The Juno mission is closing in on Jupiter. On July 4, the spacecraft enters orbit around the king of planets. Learn more about Juno HERE.

4. Spiders and Volcanoes and Glaciers, Oh My

The more data that New Horizons spacecraft sends down about Pluto and its moons, the more there is to fascinate explorers, from spider-shaped canyons to signs of glacial flow. Take a peek at the new finds on Pluto HERE.

5. World of Wonders

Hexagonal craters, mysterious mountains, eye-catching bright patches — the dwarf planet Ceres is proving to be an intriguing place. The Dawn mission is looking for clues to how it works. See the latest from Ceres HERE.

If I am in the path of totality (Hopkinsville, KY) when can I take off my glasses to view the eclipse? Can I keep them off for the entire 2 minutes and 40 seconds?

If you are viewing the partial eclipse or lead up to totality, once you no longer can see any light through your eclipse glasses, then you can take them off. As long as the moon is fully covering the Sun you are safe. I would err on the side of caution and look away from the Sun a few moments before it’s over. This is also a great time to see what is happening around you! The animals should be responding differently than normal and this would be a great time to see that. 

What kind of math is needed to get to Mars? How is the path of the lander calculated?

Which Landsat Image Do You Love?

Feeling competitive? We’ve got a game for you to play in! Tournament Earth: The Landsat Games is happening right now, and as we get to the final entries, the competition is heating up.

You can help us pick the winner by voting for one of the remaining four Landsat images of our home planet! Our competition started with 32 images, divided into categories by what they show: land, water, ice & snow, and human impact.

So, what do you think? Which one of these images is going for gold?

Land

First up, we have an image of the Markha River and surrounding Central Siberian Plateau, acquired in 2020 by Landsat 8. The hypnotic undulations of striping across the landscape carried this image to victory over the rest of the Land images -- a particularly tough category, given that these images all come from Landsat.

Water

It’s not all land, though! The bright blues and greens of this false-color image of the Atchafalaya Delta in Louisiana helped carry it to victory in the Water category. The image, taken in 2020 by Landsat 8, shows a region that’s subject to erosion of land by wind and rising sea levels.

Ice & Snow

Brrr! Did it get cold in here? That’s the finalist from the Ice and Snow category, an image of sea ice around Russia’s New Siberian Islands. The image, collected by Landsat 8 in June 2016, shows sea ice during its annual seasonal breakup.

Human Impact

Humans have been shaping the planet around us for hundreds of years. Some changes, like rice fields in the Sacramento Valley, are visible from space. Landsat 8 collected this false-color image of flooded rice fields in December 2018.

So, now it’s up to you! Which image is your favorite? There can only be one winner of Tournament Earth: The Landsat Games. Get your vote in, and then get ready to watch as we launch the next Landsat satellite, Landsat 9, in September.

The Landsat mission is a partnership between us at NASA and the U.S. Geological Survey. Together, we’ve been using Landsat satellites to collect nearly 50 years of images of our home planet.

In 2013, researchers published a shape model of asteroid Bennu based on years of observations from Puerto Rico’s Arecibo Observatory. Their model depicted a rough diamond shape. Five years later, the OSIRIS-REx spacecraft has reached the asteroid, and data obtained from spacecraft’s cameras corroborate those ground-based telescopic observations of Bennu. 

The original model closely predicted the asteroid’s actual shape, with Bennu’s diameter, rotation rate, inclination and overall shape presented almost exactly as projected! This video shows the new shape model created using data from OSIRIS-REx’s approach to the asteroid.

One outlier from the predicted shape model is the size of the large boulder near Bennu’s south pole. The ground-based shape model calculated it to be at least 33 feet (10 meters) in height. Preliminary calculations show that the boulder is closer to 164 feet (50 meters) in height, with a width of approximately 180 feet (55 meters).

Also during the approach phase, OSIRIS-REx revealed water locked inside the clays that make up Bennu. The presence of hydrated minerals across the asteroid confirms that Bennu, a remnant from early in the formation of the solar system, is an excellent specimen for the OSIRIS-REx mission to study. Get all the details about this discovery HERE.

Sakura to Supernova

This rare sight is a super-bright, massive Wolf-Rayet star. Calling forth the ephemeral nature of cherry blossoms, the Wolf-Rayet phase is a fleeting stage that only some stars go through soon before they explode.

The star, WR 124, is 15,000 light-years away in the constellation Sagittarius. It is 30 times the mass of the Sun and has shed 10 Suns worth of material – so far. As the ejected gas moves away from the star and cools, cosmic dust forms and glows in the infrared light detectable by NASA's James Webb Space Telescope.

The origin of cosmic dust that can survive a supernova blast is of great interest to astronomers for multiple reasons. Dust shelters forming stars, gathers together to help form planets, and serves as a platform for molecules to form and clump together, including the building blocks of life on Earth.

Stars like WR 124 also help astronomers understand the early history of the universe. Similar dying stars first seeded the young universe with heavy elements forged in their cores – elements that are now common in the current era, including on Earth.

The James Webb Space Telescope opens up new possibilities for studying details in cosmic dust, which is best observed in infrared wavelengths of light. Webb’s Near-Infrared Camera balances the brightness of WR 124’s stellar core and the knotty details in the fainter surrounding gas. The telescope’s Mid-Infrared Instrument reveals the clumpy structure of the gas and dust nebula of the ejected material now surrounding the star.

Celebrating 81 Years of Ingenuity

Eighty-one years ago, our world-class research center in California’s Silicon Valley was born. Ground broke on Ames Research Center on Dec. 20, 1939. It was the second aeronautical laboratory established by the National Advisory Committee for Aeronautics to perform fundamental research on all things flight. From its very beginnings, Ames was a place for innovation. Tests performed in its wind tunnels transformed military aircraft during World War II and paved the way for air travel at supersonic speeds. In the 1950s and ‘60s, its researchers looked to the stars and came up with new designs and materials for spacecraft that would make human spaceflight a reality. Fast-forward to the present, and the center contributes to virtually every major agency mission through its expertise in spacecraft entry systems, robotics, aeronautics, supercomputing, and so much more! Here are things to know about Ames.

Ames Research Center is home to the world’s largest wind tunnel.

The center is also home to Pleiades, our most powerful supercomputer.

Its modeling and simulation work plays a key role in designing new vehicles for exploring space.

The center invented heat shield materials for landing rovers on Mars.

It built robots to assist astronauts living and working aboard the International Space Station.

It launched a space telescope that revealed thousands of worlds beyond our solar system.

The center has also led multiple missions to explore the Moon.

It found water on the Moon ... more than once, and in places no one would have guessed.

The Volatiles Investigating Polar Exploration Rover is the latest lunar exploration mission led by Ames. Launching in 2023, the mobile robot will search for water ice inside craters and other places at the Moon's South Pole. Its survey will help pave the way for astronaut missions to the lunar surface beginning in 2024 as part of the Artemis program.
