We’re With You When You Fly

Did you know that "We’re With You When You Fly”? Thanks to our advancements in aeronautics, today’s aviation industry is better equipped than ever to safely and efficiently transport millions of passengers and billions of dollars worth of freight to their destinations. In fact, every U.S. Aircraft flying today and every U.S. air traffic control tower uses NASA-developed technology in some way. Here are some of our objectives in aeronautics:

Making Flight Greener

From reducing fuel emissions to making more efficient flight routes, we’re working to make flight greener. We are dedicated to improving the design of airplanes so they are more Earth friendly by using less fuel, generating less pollution and reducing noise levels far below where they are today.

Getting you safely home faster

We work with the Federal Aviation Administration to provide air traffic controllers with new tools for safely managing the expected growth in air traffic across the nation. For example, testing continues on a tool that controllers and pilots can use to find a more efficient way around bad weather, saving thousands of pounds of fuel and an average of 27 minutes flying time per tested flight. These and other NASA-developed tools help get you home faster and support a safe, efficient airspace.

Seeing Aviation’s Future

Here at NASA, we’re committed to transforming aviation through cutting edge research and development. From potential airplanes that could be the first to fly on Mars, to testing a concept of a battery-powered plane, we’re always thinking of what the future of aviation will look like.

10 Things: Journey to the Center of Mars

May the fifth be with you because history is about to be made: As early as May 5, 2018, we’re set to launch Mars InSight, the very first mission to study the deep interior of Mars. We’ve been roaming the surface of Mars for a while now, but when InSight lands on Nov. 26, 2018, we’re going in for a deeper look. Below, 10 things to know as we head to the heart of Mars.

Coverage of prelaunch and launch activities begins Thursday, May 3, on NASA Television and our homepage.

1. What’s in a name? 

"Insight" is to see the inner nature of something, and the InSight lander—a.k.a. Interior Exploration using Seismic Investigations, Geodesy and Heat Transport—will do just that. InSight will take the "vital signs" of Mars: its pulse (seismology), temperature (heat flow) and reflexes (radio science). It will be the first thorough check-up since the planet formed 4.5 billion years ago.

2. Marsquakes. 

You read that right: earthquakes, except on Mars. Scientists have seen a lot of evidence suggesting Mars has quakes, and InSight will try to detect marsquakes for the first time. By studying how seismic waves pass through the different layers of the planet (the crust, mantle and core), scientists can deduce the depths of these layers and what they're made of. In this way, seismology is like taking an X-ray of the interior of Mars.

3. More than Mars. 

InSight is a Mars mission, but it’s also so much more than that. By studying the deep interior of Mars, we hope to learn how other rocky planets form. Earth and Mars were molded from the same primordial stuff more than 4.5 billion years ago, but then became quite different. Why didn’t they share the same fate? When it comes to rocky planets, we’ve only studied one in great detail: Earth. By comparing Earth's interior to that of Mars, InSight's team hopes to better understand our solar system. What they learn might even aid the search for Earth-like planets outside our solar system, narrowing down which ones might be able to support life.

4. Robot testing. 

InSight looks a bit like an oversized crane game: When it lands on Mars this November, its robotic arm will be used to grasp and move objects on another planet for the first time. And like any crane game, practice makes it easier to capture the prize.

Want to see what a Mars robot test lab is like? Take a 360 tour.

5. The gang’s all here. 

InSight will be traveling with a number of instruments, from cameras and antennas to the heat flow probe. Get up close and personal with each one in our instrument profiles.

6. Trifecta. 

InSight has three major parts that make up the spacecraft: Cruise Stage; Entry, Descent, and Landing System; and the Lander. Find out what each one does here.

7. Solar wings. 

Mars has weak sunlight because of its long distance from the Sun and a dusty, thin atmosphere. So InSight’s fan-like solar panels were specially designed to power InSight in this environment for at least one Martian year, or two Earth years.

8. Clues in the crust. 

Our scientists have found evidence that Mars’ crust is not as dense as previously thought, a clue that could help researchers better understand the Red Planet’s interior structure and evolution. “The crust is the end-result of everything that happened during a planet’s history, so a lower density could have important implications about Mars’ formation and evolution,” said Sander Goossens of our Goddard Space Flight Center in Greenbelt, Maryland.

9. Passengers. 

InSight won’t be flying solo—it will have two microchips on board inscribed with more than 2.4 million names submitted by the public. "It's a fun way for the public to feel personally invested in the mission," said Bruce Banerdt of our Jet Propulsion Laboratory, the mission's principal investigator. "We're happy to have them along for the ride."

10. Tiny CubeSats, huge firsts. 

The rocket that will loft InSight beyond Earth will also launch a separate NASA technology experiment: two mini-spacecraft called Mars Cube One, or MarCO. These suitcase-sized CubeSats will fly on their own path to Mars behindInSight. Their goal is to test new miniaturized deep space communication equipment and, if the MarCOs make it to Mars, may relay back InSight data as it enters the Martian atmosphere and lands. This will be a first test of miniaturized CubeSat technology at another planet, which researchers hope can offer new capabilities to future missions.

Solar System: Top 5 Things to Know This Week

Here are five things you need to know about our amazing solar system this week: 

1. Perpetual Pluto-palooza

The New Horizons spacecraft continues its ongoing download of data and images from the July 14 flyby of the Pluto system. In the latest weekly release, the new images don’t disappoint, showing fine details in an exotic landscape. The New Horizons team has also described a wide range of findings about the dwarf planet’s system in its first science paper. Learn more HERE.

2. Encounter at Enceladus

The Cassini spacecraft has returned the closest images ever showing the north polar region of Saturn’s intriguing ice moon Enceladus. Scientists expected the area to be heavily cratered, but the new high-resolution Cassini images also show a landscape of stark contrasts, crisscrossed by a spidery network of gossamer-thin cracks that slice through the craters. The robotic spacecraft buzzed by the moon during the first of what will be three close encounters this year -- the last of the long mission. Next up: on Oct. 28 Cassini will deep dive right through Enceladus’ famous ice geyser plume! Learn more HERE.

3. We’re Giving You the Whole World, Every Day

We have worked with NOAA to launch a new website that shows the full, sunlit side of the Earth on a daily basis. The images come from our camera a million miles away aboard the Deep Space Climate Observatory (DSCOVR). Each daily sequence of images shows the Earth as it rotates, revealing the entire planet over the course of a day. Take a look HERE.

4. Going Big at Jupiter

We have large, new maps of Jupiter, thanks to data from the Wide Field Camera 3 on our Hubble Space Telescope. The big images provide a detailed look at how the giant planet’s features change over time. In fact, the maps are just the first in a planned series of yearly portraits of the solar system’s four outer planets. The views come as we prepare for the Juno mission to arrive at Jupiter in little less than a year. 

5. Catch a Falling Star

Meteors aren’t really falling stars, just dust and rock from deep space meeting a fiery end in Earth’s atmosphere -- but they’re a sight to behold if you can catch a glimpse. The Orionid meteors appear every year around this time, when Earth travels through an area of space littered with debris from Halley’s Comet. This year the peak will occur on the night of Wednesday, Oct. 21, into the morning of Thursday, Oct. 22. Find out how to watch HERE.

Hello!! Its wonderful to be able to ask questions, thank you!

About Perseverance, does it have a self-repair option? And as Curiosity is still operational, will they run missions together? Or will they split up to cover more distance?

Is this a sign that we're close to being able to set foot on Mars?

My final question is how do you receive the messages from such a long distance?

Thanks for all your hard work! 加油/Good luck!

Spooky Sounds from Across the Solar System

Soaring to the depths of our universe, gallant spacecraft roam the cosmos, snapping images of celestial wonders. Some spacecraft have instruments capable of capturing radio emissions. When scientists convert these to sound waves, the results are eerie to hear.

In time for Halloween, we've put together a compilation of elusive "sounds" of howling planets and whistling helium that is sure to make your skin crawl.

Listen to a few here and visit our Soundcloud for more spooky sounds. 

Cassini Ring Crossing

This eerie audio represents data collected by our Cassini spacecraft, as it crossed through the gap between Saturn and its rings on April 26, 2017, during the first dive of the mission's Grand Finale. The instrument is able to record ring particles striking the spacecraft in its data. In the data from this dive, there is virtually no detectable peak in pops and cracks that represent ring particles striking the spacecraft. The lack of discernible pops and cracks indicates the region is largely free of small particles. 

Voyager Tsunami Waves in Interstellar Space 

Listen to this howling audio from our Voyager 1 spacecraft. Voyager 1 has experienced three "tsunami waves" in interstellar space. This kind of wave occurs as a result of a coronal mass ejection erupting from the Sun. The most recent tsunami wave that Voyager experienced began in February 2014, and may still be going. Listen to how these waves cause surrounding ionized matter to ring like a bell.

Voyager Sounds of Interstellar Space

Our Voyager 1 spacecraft captured these high-pitched, spooky sounds of interstellar space from October to November 2012 and April to May 2013.

The soundtrack reproduces the amplitude and frequency of the plasma waves as "heard" by Voyager 1. The waves detected by the instrument antennas can be simply amplified and played through a speaker. These frequencies are within the range heard by human ears.

When scientists extrapolated this line even further back in time (not shown), they deduced that Voyager 1 first encountered interstellar plasma in August 2012.

Plasma Sounds at Jupiter

Ominous sounds of plasma! Our Juno spacecraft has observed plasma wave signals from Jupiter’s ionosphere. The results in this video show an increasing plasma density as Juno descended into Jupiter’s ionosphere during its close pass by Jupiter on February 2, 2017.  

Roar of Jupiter

Juno's Waves instrument recorded this supernatural sounding encounter with the bow shock over the course of about two hours on June 24, 2016. "Bow shock" is where the supersonic solar wind is heated and slowed by Jupiter's magnetosphere. It is analogous to a sonic boom on Earth. The next day, June 25, 2016, the Waves instrument witnessed the crossing of the magnetopause. "Trapped continuum radiation" refers to waves trapped in a low-density cavity in Jupiter's magnetosphere.

Two rings to shear them all!

This GIF shows a drop of insulin solution contained by surface tension in the Ring Sheared Drop device as part of an experiment conducted aboard the International Space Station. The device pins a drop of liquid between two rings and rotates one while keeping the other stationary to create shear flow, or a difference in velocity between adjacent liquid layers. Researchers used the device to study protein aggregates called amyloid fibrils, which may be related to diseases such as Alzheimer’s, Parkinson’s, and type 2 diabetes.

Scientists investigating the mechanisms of certain diseases on Earth must contend with the forces of gravity and the interaction between liquids and solid containers. These forces differ from such interfaces in the body, such as those in arteries and brain tissue, and can affect results. The Ring Sheared Drop investigation team developed a device that uses surface tension rather than a solid container to hold liquids, something possible only in microgravity!

Fluid extracted after each run will return to Earth aboard a Dragon capsule on September 30 so researchers can determine the extent of protein fibril formation, study their structure, and compare both to what happens in ground-based controls. Results could improve the fundamental understanding of how amyloid fibrils form and are transported, as well as the effects of shear at fluid interfaces relevant to conditions in the body.

5 Reasons our Space Launch System is the Backbone for Deep Space Exploration

Our Space Launch System (SLS) will be the world’s most powerful rocket, engineered to carry astronauts and cargo farther and faster than any rocket ever built. Here are five reasons it is the backbone of bold, deep space exploration missions.

5. We’re Building This Rocket to Take Humans to the Moon and Beyond

The SLS rocket is a national asset for leading new missions to deep space. More than 1,000 large and small companies in 44 states are building the rocket that will take humans to the Moon. Work on SLS has an economic impact of $5.7 billion and generates 32,000 jobs. Small businesses across the U.S. supply 40 percent of the raw materials for the rocket. An investment in SLS is an investment in human spaceflight and in American industry and will lead to applications beyond NASA.

4. This Rocket is Built for Humans

Modern deep space systems are designed and built to keep humans safe from launch to landing.  SLS provides the power to safely send the Orion spacecraft and astronauts to the Moon. Orion, powered by the European Service Module, keeps the crew safe during the mission. Exploration Ground Systems at NASA’s Kennedy Space Center in Florida, safely launches the SLS with Orion on top and recovers the astronauts and Orion after splashdown.

3. This Rocket is Engineered for a Variety of Exploration Missions

SLS is engineered for decades of human space exploration to come. SLS is not just one rocket but a transportation system that evolves to meet the needs of a variety of missions. The rocket can send more than 26 metric tons (57,000 pounds) to the Moon and can evolve to send up to 45 metric tons (99,000 pounds) to the Moon. NASA has the expertise to meet the challenges of designing and building a new, complex rocket that evolves over time while developing our nation’s capability to extend human existence into deep space.

2. This Rocket can Carry Crews and Cargos Farther, Faster

SLS’s versatile design enables it to carry astronauts their supplies as well as cargo for resupply and send science missions far in the solar system. With its power and unprecedented ability to transport heavy and large volume science payloads in a single mission, SLS can send cargos to Mars or probes even farther out in the solar system, such as to Jupiter’s moon Europa, faster than any other rocket flying today. The rocket’s large cargo volume makes it possible to design planetary probes, telescopes and other scientific instruments with fewer complex mechanical parts.

1. This Rocket Complements International and Commercial Partners

The Space Launch System is the right rocket to enable exploration on and around the Moon and even longer missions away from home. SLS makes it possible for astronauts to bring along supplies and equipment needed to explore, such as pieces of the Gateway, which will be the cornerstone of sustainable lunar exploration. SLS’s ability to launch both people and payloads to deep space in a single mission makes space travel safer and more efficient. With no buildings, hardware or grocery stores on the Moon or Mars, there are plenty of opportunities for support by other rockets. SLS and contributions by international and commercial partners will make it possible to return to the Moon and create a springboard for exploration of other areas in the solar system where we can discover and expand knowledge for the benefit of humanity.

How often do solar eclipses occur on other planets like Mars or Venus?

Venus doesn’t have a moon so it never has an eclipse. Mars does have a partial eclipse or a transit of one of its moon and you can see photos at https://www.jpl.nasa.gov/news/news.php?feature=3888

Black Holes are NICER Than You Think!

We’re learning more every day about black holes thanks to one of the instruments aboard the International Space Station! Our Neutron star Interior Composition Explorer (NICER) instrument is keeping an eye on some of the most mysterious cosmic phenomena.

We’re going to talk about some of the amazing new things NICER is showing us about black holes. But first, let’s talk about black holes — how do they work, and where do they come from? There are two important types of black holes we’ll talk about here: stellar and supermassive. Stellar mass black holes are three to dozens of times as massive as our Sun while supermassive black holes can be billions of times as massive!

Stellar black holes begin with a bang — literally! They are one of the possible objects left over after a large star dies in a supernova explosion. Scientists think there are as many as a billion stellar mass black holes in our Milky Way galaxy alone!

Supermassive black holes have remained rather mysterious in comparison. Data suggest that supermassive black holes could be created when multiple black holes merge and make a bigger one. Or that these black holes formed during the early stages of galaxy formation, born when massive clouds of gas collapsed billions of years ago. There is very strong evidence that a supermassive black hole lies at the center of all large galaxies, as in our Milky Way.

Imagine an object 10 times more massive than the Sun squeezed into a sphere approximately the diameter of New York City — or cramming a billion trillion people into a car! These two examples give a sense of how incredibly compact and dense black holes can be.

Because so much stuff is squished into such a relatively small volume, a black hole’s gravity is strong enough that nothing — not even light — can escape from it. But if light can’t escape a dark fate when it encounters a black hole, how can we “see” black holes?

Scientists can’t observe black holes directly, because light can’t escape to bring us information about what’s going on inside them. Instead, they detect the presence of black holes indirectly — by looking for their effects on the cosmic objects around them. We see stars orbiting something massive but invisible to our telescopes, or even disappearing entirely!

When a star approaches a black hole’s event horizon — the point of no return — it’s torn apart. A technical term for this is “spaghettification” — we’re not kidding! Cosmic objects that go through the process of spaghettification become vertically stretched and horizontally compressed into thin, long shapes like noodles.

Scientists can also look for accretion disks when searching for black holes. These disks are relatively flat sheets of gas and dust that surround a cosmic object such as a star or black hole. The material in the disk swirls around and around, until it falls into the black hole. And because of the friction created by the constant movement, the material becomes super hot and emits light, including X-rays.  

At last — light! Different wavelengths of light coming from accretion disks are something we can see with our instruments. This reveals important information about black holes, even though we can’t see them directly.

So what has NICER helped us learn about black holes? One of the objects this instrument has studied during its time aboard the International Space Station is the ever-so-forgettably-named black hole GRS 1915+105, which lies nearly 36,000 light-years — or 200 million billion miles — away, in the direction of the constellation Aquila.

Scientists have found disk winds — fast streams of gas created by heat or pressure — near this black hole. Disk winds are pretty peculiar, and we still have a lot of questions about them. Where do they come from? And do they change the shape of the accretion disk?

It’s been difficult to answer these questions, but NICER is more sensitive than previous missions designed to return similar science data. Plus NICER often looks at GRS 1915+105 so it can see changes over time.

NICER’s observations of GRS 1915+105 have provided astronomers a prime example of disk wind patterns, allowing scientists to construct models that can help us better understand how accretion disks and their outflows around black holes work.

NICER has also collected data on a stellar mass black hole with another long name — MAXI J1535-571 (we can call it J1535 for short) — adding to information provided by NuSTAR, Chandra, and MAXI. Even though these are all X-ray detectors, their observations tell us something slightly different about J1535, complementing each other’s data!

This rapidly spinning black hole is part of a binary system, slurping material off its partner, a star. A thin halo of hot gas above the disk illuminates the accretion disk and causes it to glow in X-ray light, which reveals still more information about the shape, temperature, and even the chemical content of the disk. And it turns out that J1535’s disk may be warped!

This isn’t the first time we have seen evidence for a warped disk, but J1535’s disk can help us learn more about stellar black holes in binary systems, such as how they feed off their companions and how the accretion disks around black holes are structured.

NICER primarily studies neutron stars — it’s in the name! These are lighter-weight relatives of black holes that can be formed when stars explode. But NICER is also changing what we know about many types of X-ray sources. Thanks to NICER’s efforts, we are one step closer to a complete picture of black holes. And hey, that’s pretty nice!
