Why We Celebrate Search and Rescue Technologies on 4/06

Today (4/06), we celebrate the special radio frequency transmitted by emergency beacons to the international search and rescue network. 

This 406 MHz frequency, used only for search and rescue, can be "heard" by satellites hundreds of miles above the ground! The satellites then "forward" the location of the beacon back to Earth, helping first responders locate people in distress worldwide, whether from a plane crash, a boating accident or other emergencies.

Our Search and Rescue office, based out of our Goddard Space Flight Center, researches and develops emergency beacon technology, passing the technology to companies who manufacture the beacons, making them available to the public at retail stores. The beacons are designed for personal, maritime and aviation use.

The search and rescue network, Cospas-Sarsat, is an international program that ensures the compatibility of distress alert services with the needs of users. Its current space segment relies on instruments onboard low-Earth and geosynchronous orbiting satellites, hundreds to thousands of miles above us. 

Space instruments forward distress signals to the search and rescue ground segment, which is operated by partner organizations around the world! They manage specific regions of the ground network. For example, the National Oceanic and Atmospheric Administration (NOAA) operates the region containing the United States, which reaches across the Atlantic and Pacific Oceans as well as parts of Central and South America.

NOAA notifies organizations that coordinate search and rescue efforts of a 406 MHz distress beacon's activation and location. Within the U.S., the U.S. Air Force responds to land-based emergencies and the U.S. Coast Guard responds to water-based emergencies. Local public service organizations like police and fire departments, as well as civilian volunteers, serve as first responders.

Here at NASA, we research, design and test search and rescue instruments and beacons to refine the existing network. Aeronautical beacon tests took place at our Langley Research Center in 2015. Using a 240-foot-high structure originally used to test Apollo spacecraft, our Search and Rescue team crashed three planes to test the survivability of these beacons, developing guidelines for manufacturers and installation into aircraft.

In the future, first responders will rely on a new constellation of search and rescue instruments on GPS systems on satellites in medium-Earth orbit, not hundreds, but THOUSANDS of miles overhead. These new instruments will enable the search and rescue network to locate a distress signal more quickly than the current system and achieve accuracy an order of magnitude better, from a half mile to approximately 300 feet. Our Search and Rescue office is developing second-generation 406 MHz beacons that make full use of this new system.

We will also incorporate these second-generation beacons into the Orion Crew Survival System. The Advanced Next-Generation Emergency Locator (ANGEL) beacons will be attached to astronaut life preservers. After splashdown, if the Orion crew exits the capsule due to an emergency, these beacons will make sure we know the exact location of floating astronauts! Our Johnson Space Center is testing this technology for used in future human spaceflight and exploration missions.

If you're the owner of an emergency beacon, remember that beacon registration is free, easy and required by law.

Celebrating 17 Years of NASA’s ‘Little Earth Satellite That Could’

The satellite was little— the size of a small refrigerator; it was only supposed to last one year and constructed and operated on a shoestring budget — yet it persisted.

After 17 years of operation, more than 1,500 research papers generated and 180,000 images captured, one of NASA’s pathfinder Earth satellites for testing new satellite technologies and concepts comes to an end on March 30, 2017. The Earth Observing-1 (EO-1) satellite will be powered off on that date but will not enter Earth’s atmosphere until 2056. 

“The Earth Observing-1 satellite is like The Little Engine That Could,” said Betsy Middleton, project scientist for the satellite at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. 

To celebrate the mission, we’re highlighting some of EO-1’s notable contributions to scientific research, spaceflight advancements and society. 

Scientists Learn More About Earth in Fine Detail

EO-1 carried the Advanced Land Imager that improved observations of forest cover, crops, coastal waters and small particles in the air known as aerosols. These improvements allowed researchers to identify smaller features on a local scale such as floods and landslides, which were especially useful for disaster support. 

On the night of Sept. 6, 2014, EO-1’s Hyperion observed the ongoing eruption at Holuhraun, Iceland as shown in the above image. Partially covered by clouds, this scene shows the extent of the lava flows that had been erupting.

EO-1’s other key instrument Hyperion provided an even greater level of detail in measuring the chemical constituents of Earth’s surface— akin to going from a black and white television of the 1940s to the high-definition color televisions of today. Hyperion’s level of sophistication doesn’t just show that plants are present, but can actually differentiate between corn, sorghum and many other species and ecosystems. Scientists and forest managers used these data, for instance, to explore remote terrain or to take stock of smoke and other chemical constituents during volcanic eruptions, and how they change through time.  

Crowdsourced Satellite Images of Disasters   

EO-1 was one of the first satellites to capture the scene after the World Trade Center attacks (pictured above) and the flooding in New Orleans after Hurricane Katrina. EO-1 also observed the toxic sludge in western Hungary in October 2010 and a large methane leak in southern California in October 2015. All of these scenes, which EO-1 provided quick, high-quality satellite imagery of the event, were covered in major news outlets. All of these scenes were also captured because of user requests. EO-1 had the capability of being user-driven, meaning the public could submit a request to the team for where they wanted the satellite to gather data along its fixed orbits. 

This image shows toxic sludge (red-orange streak) running west from an aluminum oxide plant in western Hungary after a wall broke allowing the sludge to spill from the factory on October 4, 2010.

 Artificial Intelligence Enables More Efficient Satellite Collaboration

This image of volcanic activity on Antarctica’s Mount Erebus on May 7, 2004 was taken by EO-1’s Advanced Land Imager after sensing thermal emissions from the volcano. The satellite gave itself new orders to take another image several hours later. Credit: Earth Observatory

EO-1 was among the first satellites to be programmed with a form of artificial intelligence software, allowing the satellite to make decisions based on the data it collects. For instance, if a scientist commanded EO-1 to take a picture of an erupting volcano, the software could decide to automatically take a follow-up image the next time it passed overhead. The Autonomous Sciencecraft Experiment software was developed by NASA’s Jet Propulsion Laboratory in Pasadena, California, and was uploaded to EO-1 three years after it launched. 

This image of Nassau Bahamas was taken by EO-1’s Advanced Land Imager on Oct 8, 2016, shortly after Hurricane Matthew hit. European, Japanese, Canadian, and Italian Space Agency members of the international coalition Committee on Earth Observation Satellites used their respective satellites to take images over the Caribbean islands and the U.S. Southeast coastline during Hurricane Matthew. Images were used to make flood maps in response to requests from disaster management agencies in Haiti, Dominican Republic, St. Martin, Bahamas, and the U.S. Federal Emergency Management Agency.

The artificial intelligence software also allows a group of satellites and ground sensors to communicate and coordinate with one another with no manual prompting. Called a "sensor web", if a satellite viewed an interesting scene, it could alert other satellites on the network to collect data during their passes over the same area. Together, they more quickly observe and downlink data from the scene than waiting for human orders. NASA's SensorWeb software reduces the wait time for data from weeks to days or hours, which is especially helpful for emergency responders. 

Laying the Foundation for ‘Formation Flying’

This animation shows the Rodeo-Chediski fire on July 7, 2002, that were taken one minute apart by Landsat 7 (burned areas in red) and EO-1 (burned areas in purple). This precision formation flying allowed EO-1 to directly compare the data and performance from its land imager and the Landsat 7 ETM+. EO-1’s most important technology goal was to test ALI for future Landsat satellites, which was accomplished on Landsat 8. Credit: NASA’s Goddard Space Flight Center

EO-1 was a pioneer in precision “formation flying” that kept it orbiting Earth exactly one minute behind the Landsat 7 satellite, already in orbit. Before EO-1, no satellite had flown that close to another satellite in the same orbit. EO-1 used formation flying to do a side-by-side comparison of its onboard ALI with Landsat 7’s operational imager to compare the products from the two imagers. Today, many satellites that measure different characteristics of Earth, including the five satellites in NASA's A Train, are positioned within seconds to minutes of one another to make observations on the surface near-simultaneously.

Gobble Up These Black (Hole) Friday Deals!

Welcome to our 6th annual annual Black Hole Friday! Check out these black hole deals from the past year as you prepare to head out for a shopping spree or hunker down at home to avoid the crowds.

First things first, black holes have one basic rule: They are so incredibly dense that to escape their surface you’d have to travel faster than light. But light speed is the cosmic speed limit . . . so nothing can escape a black hole’s surface!

Black hole birth announcements

Some black holes form when a very large star dies in a supernova explosion and collapses into a superdense object. This is even more jam-packed than the crowds at your local mall — imagine an object 10 times more massive than the Sun squeezed into a sphere with the diameter of New York City!

Some of these collapsing stars also signal their destruction with a huge burst of gamma rays. Our Fermi Gamma-ray Space Telescope and Neil Gehrels Swift Observatory continuously seek out the signals of these gamma ray bursts — black hole birth announcements that come to us from across the universe.

NICER black holes

There are loads of stellar mass black holes, which are just a few 10s of times the Sun’s mass, in our home galaxy alone — maybe even hundreds of millions of them! Our Neutron Star Interior Composition Explorer, or NICER for short, experiment on the International Space Station has been studying some of those relatively nearby black holes.

Near one black hole called GRS 1915+105, NICER found disk winds — fast streams of gas created by heat or pressure. Scientists are still figuring out some puzzles about these types of wind. Where do they come from, for example? And do they change the way material falls into the black hole? Every new example of these disk winds helps astronomers get closer to answering those questions.

Merging monster black holes

But stellar mass black holes aren’t the only ones out there. At the center of nearly every large galaxy lies a supermassive black hole — one with the mass of millions or billions of Suns smooshed into a region no bigger than our solar system.

There’s still some debate about how these monsters form, but astronomers agree that they certainly can collide and combine when their host galaxies collide and combine. Those black holes will have a lot of gas and dust around them. As that material is pulled into the black hole it will heat up due to friction and other forces, causing it to emit light.  A group of scientists wondered what light it would produce and created this mesmerizing visualization showing that most of the light produced around these two black holes is UV or X-ray light. We can’t see those wavelengths with our own eyes, but many telescopes can. Models like this could help scientists know what to look for to spot a merger.

Black holes power bright gamma ray lights

It also turns out that these supermassive black holes are the source of some of the brightest objects in the gamma ray sky! In a type of galaxy called active galactic nuclei (also called “AGN” for short) the central black hole is surrounded by a disk of gas and dust that’s constantly falling into the black hole.

But not only that, some of those AGN have jets of energetic particles that are shooting out from near the black hole at nearly the speed of light! Scientists are studying these jets to try to understand how black holes — which pull everything in with their huge amounts of gravity — provide the energy needed to propel the particles in these jets. If that jet is pointed directly at us, it can appear super-bright in gamma rays and we call it a blazar. These blazars make up more than half of the sources our Fermi space telescope sees.

Catching particles from near a black hole

Sometimes scientists get a two-for-one kind of deal when they’re looking for black holes. Our colleagues at the IceCube Neutrino Observatory actually caught a particle from a blazar 4 billion light-years away. IceCube lies a mile under the ice in Antarctica and uses the ice itself to detect neutrinos, tiny speedy particles that weigh almost nothing and rarely interact with anything. When IceCube caught a super-high-energy neutrino and traced its origin to a specific area of the sky, they turned to the astronomical community to pinpoint the source.

Our Fermi spacecraft scans the entire sky about every three hours and for months it had observed a blazar producing more gamma rays than usual. Flaring is a common characteristic in blazars, so this didn’t attract special attention. But when the alert from IceCube came through, scientists realized the neutrino and the gamma rays came from the same patch of sky! This method of using two or more kinds of signals to learn about one event or object is called multimessenger astronomy, and it’s helping us learn a lot about the universe.

5 Examples of How Our Satellite Data is Helping the Planet

We could talk all day about how our satellite data is crucial for Earth science…tracking ocean currents, monitoring natural disasters, soil mapping – the list goes on and on.

But did you know there is another way this data can improve life here on Earth?

Our satellite data can be used to build businesses and commercial products – but finding and using this data has been a daunting task for many potential users because it’s been stored across dozens of websites.

Until now.

Our Technology Transfer program has just released their solution to make finding data easier, called The NASA Remote Sensing Toolkit (RST).

RST offers an all-in-one approach to finding and using our Earth Science data, the tools needed to analyze it, and software to build your own tools.  

Before, we had our petabytes on petabytes of information spread out across dozens of websites – not to mention the various software tools needed to interpret the data. 

Now, RST helps users find everything they need while having only one browser open.

Feeling inspired to innovate with our data? Here are just a few examples of how other companies have taken satellite data and turned it into products, known as NASA spinoffs, that are helping our planet today.

1. Bringing Landscape into Focus

We have a number of imaging systems for locating fires, but none were capable of identifying small fires or indicating the flames’ intensity. Thanks to a series of Small Business Innovation Research (SBIR) contracts between our Ames Research Center and Xiomas Technologies LLC, the Wide Area Imager aerial scanner does just that. While we and the U.S. Forest Service use it for fire detection, the tool is also being used by municipalities for detailed aerial surveillance projects.

2. Monitoring the Nation’s Forests with the Help of Our Satellites

Have you ever thought about the long-term effects of natural disasters, such as hurricanes, on forest life? How about the big-time damage caused by little pests, like webworms? 

Our Stennis Space Center did, along with multiple forest services and environmental threat assessment centers. They partnered to create an early warning system to identify, characterize, and track disturbances from potential forest threats using our satellite data. The result was ForWarn, which is now being used by federal and state forest and natural resource managers.

3. Informing Forecasts of Crop Growth

Want to hear a corny story?

Every year Stennis teams up with the U.S. Department of Agriculture to host a program called Ag 20/20 to utilize remote sensing technology for operational use in agricultural crop management practices at the level of individual farms. During Ag 20/20 in 2000, an engineering contractor developed models for using our satellite data to predict corn crop yield. The model was eventually sold to Genscape Inc., which has commercialized it as LandViewer. Sold under a subscription model, LandViewer software provides predictions of corn production to ethanol plants and grain traders.

4. Water Mapping Technology Rebuilds Lives in Arid Regions

No joking around here. Lives depend on the ability to find precious water in areas with little of it.  

Using our Landsat satellite and other topographical data, Radar Technologies International developed an algorithm-based software program that can locate underground water sources. Working with international organizations and governments, the firm is helping to provide water for refugees and other people in drought-stricken regions such as Kenya, Sudan, and Afghanistan.

5. Satellite Maps Deliver More Realistic Gaming

Are you more of the creative type? This last entry used satellite data to help people really get into their gameplay.

When Electronic Arts (EA) decided to make SSX, a snowboarding video game, it faced challenges in creating realistic-looking mountains. The solution was our ASTER Global Digital Elevation Map, made available by our Jet Propulsion Laboratory, which EA used to create 28 real-life mountains from 9 different ranges for its award-winning game.

🏊‍♂️ Down for a dip in the Cosmic Reef?

Nicknamed the Cosmic Reef because it resembles an undersea world, this is a vast star-forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way.

Released in April 2020 to celebrate the Hubble Space Telescope’s 30th anniversary, the reef showcases the beauty and mystery of space in this complex image of starbirth. Throughout its decades of discoveries, Hubble has yielded over 1.5 million observations, providing data that astronomers around the world have used to write more than 18,000 peer-reviewed scientific publications, making it the most prolific space observatory in history.

Two Steps Forward in the Search for Life on Mars

We haven’t found aliens but we are a little further along in our search for life on Mars thanks to two recent discoveries from our Curiosity Rover.

We detected organic molecules at the harsh surface of Mars! And what’s important about this is we now have a lot more certainty that there’s organic molecules preserved at the surface of Mars. We didn’t know that before.

One of the discoveries is we found organic molecules just beneath the surface of Mars in 3 billion-year-old sedimentary rocks.

Second, we’ve found seasonal variations in methane levels in the atmosphere over 3 Mars years (nearly 6 Earth years). These two discoveries increase the chances that the record of habitability and potential life has been preserved on the Red Planet despite extremely harsh conditions on the surface.

Both discoveries were made by our chem lab that rides aboard the Curiosity rover on Mars.

Here’s an image from when we installed the SAM lab on the rover. SAM stands for “Sample Analysis at Mars” and SAM did two things on Mars for this discovery.

One - it tested Martian rocks. After the arm selects a sample of pulverized rock, it heats up that sample and sends that gas into the chamber, where the electron stream breaks up the chemicals so they can be analyzed.

What SAM found are fragments of large organic molecules preserved in ancient rocks which we think come from the bottom of an ancient Martian lake. These organic molecules are made up of carbon and hydrogen, and can include other elements like nitrogen and oxygen. That’s a possible indicator of ancient life…although non-biological processes can make organic molecules, too.

The other action SAM did was ‘sniff’ the air.

When it did that, it detected methane in the air. And for the first time, we saw a repeatable pattern of methane in the Martian atmosphere. The methane peaked in the warm, summer months, and then dropped in the cooler, winter months.

On Earth, 90 percent of methane is produced by biology, so we have to consider the possibility that Martian methane could be produced by life under the surface. But it also could be produced by non-biological sources. Right now, we don’t know, so we need to keep studying the Mars!

One of our upcoming Martian missions is the InSight lander. InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to give the Red Planet its first thorough checkup since it formed 4.5 billion years ago. It is the first outer space robotic explorer to study in-depth the "inner space" of Mars: its crust, mantle, and core.

Finding methane in the atmosphere and ancient carbon preserved on the surface gives scientists confidence that our Mars 2020 rover and ESA’s (European Space Agency's) ExoMars rover will find even more organics, both on the surface and in the shallow subsurface.

Normal Things…Done in a Not So Normal Way

Floating around in zero gravity may sound like a blast, but it can actually present a lot of challenges to things we do everyday here on Earth with little to no thought. Here are a few ways that astronauts on the International Space Station complete normal tasks in orbit:

1) Washing Hair

You can’t just have a shower on the space station because the water would come out of the faucet and float all over the place. In this video, NASA Astronaut Karen Nyberg demonstrates how she uses a bag of water, no rinse shampoo, a towel and her comb to wash her hair.

2) Drinking Coffee

Believe it or not, there are special cups used on the space station to drink coffee from the new ISSpresso machine. I mean, you wouldn’t want hot coffee floating around in the air…would you? Previously, astronauts drank coffee from plastic bags, but let’s face it, that sounds pretty unenjoyable. Now, there are zero Gravity coffee cups, and an Italian espresso machine aboard the International Space Station! These cups were created with the help of capillary flow experiments conducted in space.

3) Sleeping

There’s nothing like crawling into bed after a long day, but astronauts can’t exactly do that while they’re in microgravity. Instead of beds, crew members use sleeping bags attached to the walls of their small crew cabins. They are able to zipper themselves in so that they don’t float around while they’re asleep. This may sound uncomfortable, but some astronauts, like Scott Kelly, say that they sleep better in space than they do on Earth!

4) Exercising 

Exercising in general is an important part of a daily routine. In space, it even helps prevent the effects of bone and muscle loss associated with microgravity. Typically, astronauts exercise two hours per day, but the equipment they use is different than here on Earth. For example, if an astronaut wants to run on the treadmill, they have to wear a harness and bungee cords so that they don’t float away.
