The Exploration Behind the Inspiration at NASA

Are we alone? How did we get here? Where are we headed?

At NASA, our mission is to explore. We visit destinations in our solar system and study worlds beyond to better understand these big questions.

We also dream. We dream of traveling to distant worlds, and what that might be like. In the video above you can see fanciful, imagined adventures to real places we’ve studied at NASA.

How We Did It

Check out how we created these otherworldly scenes in the video below. A NASA videographer used green screens to add motion and real people to bring life to our series of solar system and exoplanet travel posters.

Let’s dive into one example from the video. The shot of kayaking on Titan showcases the real rivers and lakes of liquid methane and ethane that slosh and flow on Saturn's largest moon. Titan's mysterious surface was revealed by our Cassini spacecraft, which also deployed the European Space Agency’s Huygens probe to the surface. The atmosphere on Titan is so thick, and the gravity so light, that with each strike of a paddle, you might be lofted above the swift current as you ride the tides through a narrow strait called the Throat of Kraken. NASA scientist Mike Malaska studies Titan and collaborated on the poster featured in the video. His research informed the artwork, and so did a hobby: kayaking. Those ultra-cold chemical seas might be even more of a challenge than shown here. Your boat might crack, or even dissolve, Malaska said.

We’ll learn more about Titan when our Dragonfly mission of dual quadcoptors — rotorcraft with eight blades each — visits the icy moon in 2034.

Science Never Stops

Our understanding of other worlds is always evolving, and sometimes we learn new details after we illustrate our science. In one of our travel posters, we show a traveler standing on the surface of exoplanet Kepler-16b with two shadows formed by the planet’s two suns. The planet does indeed orbit two stars, but with later size and mass refinements, we now think it would be hard to stand there and enjoy a binary sunset. There isn't a solid surface to stand on a gas planet, and that's what Kepler-16b now appears to be!

In addition to sharing how sublime science can be, these scenes are a reminder that there are lots of careers in the space program, not just scientist, engineer, or astronaut. A creative team at NASA’s Jet Propulsion Laboratory in Southern California produced the travel posters, originally to help share the work of NASA's Exoplanet Exploration Program. They are the result of lots of brainstorming and discussion with real NASA scientists, engineers, and expert communicators. The video versions of these spacey travel scenes were produced by visualization experts at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

All of this work is meant to inspire, and to explore the edge of possibility. It’s also an invitation. With science, we’re stepping into the future. Join us?

El Observatorio Abbey Ridge de Dave Lane tomó este video del asteroide (99942) Apophis mientras "pasaba zumbando" por la Tierra.

Aunque la aparición de 2021 no está muy cerca de la Tierra (Aprox. a 44 distancias lunares), el Asteoide Apophis es de particular interés porque en 2029 se acercará a unos ~40.000 km.

Las exposiciones fueron de 20 segundos durante aproximadamente 30 minutos. El asteroide es la "estrella" en movimiento cerca del centro del video.

A Total Solar Eclipse Over South America

On Dec. 14, 2020, a total solar eclipse will pass over Chile and Argentina.

Solar eclipses happen when the Moon lines up just right between the Sun and Earth, allowing it to cast its shadow on Earth’s surface. People within the outer part of the Moon’s shadow will see the Sun partially blocked by the Moon, and those in the inner part of the shadow will see a total solar eclipse.

The Moon’s orbit around Earth is slightly tilted, meaning this alignment doesn’t happen on every orbit. Total solar eclipses happen somewhere on Earth about once every 18 months.

During a total solar eclipse, the Moon blocks out the Sun’s bright face, revealing its comparatively faint outer atmosphere, the corona. This provides Sun-watchers and scientists alike with a rare chance to see the solar corona closer to the Sun’s surface than is usually possible.

Scientists can take advantage of this unparalleled view — and solar eclipses’ unique effects on Earth’s atmosphere — to perform unique scientific studies on the Sun and its effects on Earth. Several NASA-funded science teams performed such studies during the total solar eclipse in the United States on Aug. 21, 2017. Read about what they’ve learned so far.

Watching the eclipse

We’ll be carrying images of December’s eclipse — courtesy of Pontificia Universidad Católica de Chile — on NASA TV and on the agency’s website starting at 9:40 a.m. EST on Dec. 14.

We’ll also have a live show in Spanish from 10:30 – 11:30 a.m. EST featuring views of the eclipse and NASA scientists.

If you’re observing the eclipse in person, remember that it’s never safe to look directly at the uneclipsed or partially eclipsed Sun. You can use special solar viewing glasses (NOT sunglasses) or an indirect method like pinhole projection to watch the eclipse in person.

For people in the path of totality, there will be a few brief moments when it is safe to look directly at the eclipse. Only once the Moon has completely covered the Sun and there is no sunlight shining is it safe to look at the eclipse. Make sure you put your eclipse glasses back on or return to indirect viewing before the first flash of sunlight appears around the Moon’s edge.

Mira el eclipse en vivo comentado por científicas de la NASA de 10:30 a 11:30 a.m. EST el 14 de diciembre en NASA TV y la página web de la agencia.

NGC 6888, también conocida como la Nebulosa Creciente, es una burbuja cósmica de unos 25 años luz de diámetro, arrastrada por los vientos de su estrella central, brillante y masiva. La estrella central de NGC 6888 está clasificada como una estrella Wolf-Rayet (WR 136). La estrella se desprende de su envoltura exterior con un fuerte viento estelar., expulsando el equivalente a la masa del Sol cada 10.000 años.
