Send Your Name to Jupiter

You’re invited to sign your name to a poem written by the U.S. Poet Laureate, Ada Limón. The poem connects two water worlds — Earth, yearning to reach out and understand what makes a world habitable, and Europa, waiting with secrets yet to be explored.

The poem will be engraved on Europa Clipper, along with participants' names that will be physically etched onto microchips mounted on the spacecraft. Together, the poem and names will travel 1.8 billion miles to the Jupiter system.

Signing up is easy! Just go to this site to sign your name to the poem and get on board. We also have a Spanish-language site where you can send your name en español: Envía tu nombre aquí.

The Europa Clipper launch window opens in October 2024, but don’t wait – everyone’s names need to be received by December 31 this year so they can be loaded onto the spacecraft in time. We hope you’ll be riding along with us! Follow the mission at europa.nasa.gov.

How long did it take to build the rover??

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.

Is it at all possible to send a drone into a black hole and collect the data of what it’s like inside? If not, how close do you we are to possibly achieving that?

Bringing The Space Station Perspective to Earth in VR!

Only a few humans ever get to experience the awe-inspiring vantage point provided by the space station, but a new virtual reality (VR) experience, Space Explorers: The ISS Experience (ISS Experience), attempts to bring this perspective back to Earth for the rest of us.

Partnering with the ISS National Lab and Time, a team from Felix and Paul Studios launched a high quality 360 degree camera to space to help tell the story of science and life aboard the orbiting laboratory.

The project, currently in the process of being filmed by the station astronauts themselves, serves as an outreach project as well a technology demonstration, testing the limits of filming in the harsh environment of space.

The camera flew to the station on 16th SpaceX commercial resupply services mission in December 2018 along with a number of other scientific experiments.

Since then, the team has recorded many moments, including the SPHERES robots flying around the station (see below) , the growing and harvesting of vegetables, jam session among the astronauts, crew meals and the arrival of new astronauts.

So far, the footage coming back seems to be achieving the goal of immersing audiences in science and life aboard the space station. NASA astronaut Sunita Williams got the chance to watch some of the initial footage and says it was like I was back on the station.

While most of the filming has been completed, the biggest technical challenge is yet to come: capturing a spacewalk in virtual reality. The team expects to launch a new camera for spacewalk filming and begin production of spacewalk filming in 2020.

Studying Storms from Air and Space

Technology we’ve developed is helping study the movement of storms.  

From satellites that can slice through a hurricane with 3-D vision to computer models of gale force winds, scientists now have unprecedented ways of viewing extreme weather.

This August, we’re sending an unmanned aircraft called a Global Hawk to study hurricanes. This mission is called the “East Pacific Origins and Characteristics of Hurricanes,” or EPOCH. It will fly over developing tropical storms to investigate how they progress and intensify. 

The three instruments aboard this Global Hawk aircraft will map out 3-D patterns of temperature, pressure, humidity, precipitation and wind speed as well as the role of the East Pacific Ocean in global cyclone formation. These measurements will help scientists better understand the processes that control storm intensity and the role of the East Pacific Ocean in global cyclone formation.

To better understand hurricane formation and intensity, scientists also utilize models and other observations.

Satellites such as our Global Precipitation Measurement Mission, or GPM, and computer models can analyze key stages of storm intensification.  

In September 2016, GPM captured Hurricane Matthew’s development from a Category 1 to Category 5 hurricane in less than 24 hours.  

Extreme rainfall was seen in several stages of the storm, causing significant flooding and landslides when it passed by Cuba, Haiti and the Dominican Republic.

By combining model and observed data, scientists can analyze storms like never before. They can also better understand how hurricanes and other powerful storms can potentially impact society.

What's Up? - May 2018

What’s Up For May?

The Moon and Saturn meet Mars in the morning as our InSight spacecraft launches to the Red Planet on May 5!

You won't want to miss red Mars in the southern morning skies this month.

InSight, our first mission to explore Mars' deep interior, launches on May 5th with a launch window that begins at 4:05 a.m. PDT and lasts for two hours.

Some lucky viewers in central and southern California and even parts of the Mexican Pacific coast will get a chance to see the spacecraft launch with their unaided eyes AND its destination, Mars, at the same time.

Mars shines a little brighter than last month, as it approaches opposition on July 27th. That's when Mars and the Sun will be on opposite sides of the Earth. This will be Mars' closest approach to Earth since 2003! 

Compare the planet's increases in brightness with your own eyes between now and July 27th. 

The Eta Aquarid meteor shower will be washed out by the Moon this month, but if you are awake for the InSight launch anyway, have a look. This shower is better viewed from the southern hemisphere, but medium rates of 10 to 30 meteors per hour MAY be seen before dawn.

Of course, you could travel to the South Pacific to see the shower at its best!

There's no sharp peak to this shower--just several nights with good rates, centered on May 6th. 

Jupiter reaches opposition on May 9th, heralding the best Jupiter-observing season, especially for mid-evening viewing. That's because the king of the planets rises at sunset and sets at dawn. 

Wait a few hours after sunset, when Jupiter is higher in the sky, for the best views. If you viewed Jupiter last month, expect the view to be even better this month!

Watch the full What’s Up for May Video: 

There are so many sights to see in the sky. To stay informed, subscribe to our What’s Up video series on Facebook. Make sure to follow us on Tumblr for your regular dose of space: http://nasa.tumblr.com.   

What’s Up for November?

November weather can be challenging for backyard astronomers, but the moon is a reliable target, even when there are clouds.

Did you know that the moon takes about 29 days to go around the Earth once? It also takes the moon about 29 days to spin on its axis. This causes the same side of the moon to always face Earth.

On Nov. 3, the moon reaches last quarter when it rises at midnight and sets at noon. This is a great time to see the moon in the morning sky.

On Nov. 11, the new moon isn’t visible, because it’s between Earth and the sun, and the unlit side faces Earth. In the days after the new moon, the slender crescent gets bigger and brighter. Look just after sunset on Nov. 13 and 14 near the setting sun in the western sky.

The next phase on Nov. 19 is called the first quarter, because the moon has traveled one quarter of its 29-day orbit around Earth. The moon rises at noon and sets at midnight, so you can see it in the afternoon sky. It will rise higher in the sky after dark. That’s when you can look for the areas where four of the six Apollo missions landed on the moon! You won’t see the landers, flag or footprints, but it’s fun and easy to see these historic places with your own eyes or with binoculars.

To see the area: Look for three dark, smooth maria, or seas. The middle one is the Sea of Tranquility. Apollo 11 landed very near a bright crater on the edge of this mare in 1969. The Apollo 15, 16 and 17 landing areas form the points of a triangle above and below the Apollo 11 site.

On Nov. 25, you can see the full moon phase, which occurs on the 14th day of the lunar cycle. The moon will rise at sunset and will be visible all night long, setting at sunrise.

On Thanksgiving (Nov. 26), the 15-day-old moon will rise an hour after sunset. You may even see some interesting features! And this is a great time to see the impact rays of some of the larger craters.

Earth from Afar

“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.” - Neil Armstrong, Apollo 11

This week we're celebrating Earth Day 2018 with some of our favorite images of Earth from afar...

At 7.2 million Miles...and 4 Billion Miles

Voyager famously captured two unique views of our homeworld from afar. One image, taken in 1977 from a distance of 7.3 million miles (11.7 million kilometers) (above), showed the full Earth and full Moon in a single frame for the first time in history. The second (below), taken in 1990 as part of a “family portrait of our solar system from 4 billion miles (6.4 billion kilometers), shows Earth as a tiny blue speck in a ray of sunlight.” This is the famous “Pale Blue Dot” image immortalized by Carl Sagan.

“This was our willingness to see the Earth as a one-pixel object in a far greater cosmos,” Sagan’s widow, Ann Druyan said of the image. “It's that humility that science gives us. That weans us from our childhood need to be the center of things. And Voyager gave us that image of the Earth that is so heart tugging because you can't look at that image and not think of how fragile, how fragile our world is. How much we have in common with everyone with whom we share it; our relationship, our relatedness, to everyone on this tiny pixel."

A Bright Flashlight in a Dark Sea of Stars

Our Kepler mission captured Earth’s image as it slipped past at a distance of 94 million miles (151 million kilometers). The reflection was so extraordinarily bright that it created a saber-like saturation bleed across the instrument’s sensors, obscuring the neighboring Moon.

Hello and Goodbye

This beautiful shot of Earth as a dot beneath Saturn’s rings was taken in 2013 as thousands of humans on Earth waved at the exact moment the spacecraft pointed its cameras at our home world. Then, in 2017, Cassini caught this final view of Earth between Saturn’s rings as the spacecraft spiraled in for its Grand Finale at Saturn.

‘Simply Stunning’

"The image is simply stunning. The image of the Earth evokes the famous 'Blue Marble' image taken by astronaut Harrison Schmitt during Apollo 17...which also showed Africa prominently in the picture." -Noah Petro, Deputy Project Scientist for our Lunar Reconnaissance Orbiter mission.

Goodbye—for now—at 19,000 mph

As part of an engineering test, our OSIRIS-REx spacecraft captured this image of Earth and the Moon in January 2018 from a distance of 39.5 million miles (63.6 million kilometers). When the camera acquired the image, the spacecraft was moving away from our home planet at a speed of 19,000 miles per hour (8.5 kilometers per second). Earth is the largest, brightest spot in the center of the image, with the smaller, dimmer Moon appearing to the right. Several constellations are also visible in the surrounding space.

The View from Mars

A human observer with normal vision, standing on Mars, could easily see Earth and the Moon as two distinct, bright "evening stars."

Moon Photobomb

"This image from the Deep Space Climate Observatory (DSCOVR) satellite captured a unique view of the Moon as it moved in front of the sunlit side of Earth in 2015. It provides a view of the far side of the Moon, which is never directly visible to us here on Earth. “I found this perspective profoundly moving and only through our satellite views could this have been shared.” - Michael Freilich, Director of our Earth Science Division.

Eight Days Out

Eight days after its final encounter with Earth—the second of two gravitational assists from Earth that helped boost the spacecraft to Jupiter—the Galileo spacecraft looked back and captured this remarkable view of our planet and its Moon. The image was taken from a distance of about 3.9 million miles (6.2 million kilometers).

A Slice of Life

Earth from about 393,000 miles (633,000 kilometers) away, as seen by the European Space Agency’s comet-bound Rosetta spacecraft during its third and final swingby of our home planet in 2009.

So Long Earth

The Mercury-bound MESSENGER spacecraft captured several stunning images of Earth during a gravity assist swingby of our home planet on Aug. 2, 2005.

Earth Science: Taking a Closer Look

Our home planet is a beautiful, dynamic place. Our view from Earth orbit sees a planet at change. Check out more images of our beautiful Earth here.
