What’s In Store For 2017 At NASA?

Travel Posters of Fantastic Excursions

What would the future look like if people were regularly visiting to other planets and moons? These travel posters give a glimpse into that imaginative future. Take a look and choose your destination:

The Grand Tour

Our Voyager mission took advantage of a once-every-175-year alignment of the outer planets for a grand tour of the solar system. The twin spacecraft revealed details about Jupiter, Saturn, Uranus and Neptune – using each planet’s gravity to send them on to the next destination.

Mars

Our Mars Exploration Program seeks to understand whether Mars was, is, or can be a habitable world. This poster imagines a future day when we have achieved our vision of human exploration of the Red Planet and takes a nostalgic look back at the great imagined milestones of Mars exploration that will someday be celebrated as “historic sites.”

Earth

There’s no place like home. Warm, wet and with an atmosphere that’s just right, Earth is the only place we know of with life – and lots of it. Our Earth science missions monitor our home planet and how it’s changing so it can continue to provide a safe haven as we reach deeper into the cosmos.

Venus

The rare science opportunity of planetary transits has long inspired bold voyages to exotic vantage points – journeys such as James Cook’s trek to the South Pacific to watch Venus and Mercury cross the face of the sun in 1769. Spacecraft now allow us the luxury to study these cosmic crossings at times of our choosing from unique locales across our solar system.

Ceres

Ceres is the closest dwarf planet to the sun. It is the largest object in the main asteroid belt between Mars and Jupiter, with an equatorial diameter of about 965 kilometers. After being studied with telescopes for more than two centuries, Ceres became the first dwarf planet to be explored by a spacecraft, when our Dawn probe arrived in orbit in March 2015. Dawn’s ongoing detailed observations are revealing intriguing insights into the nature of this mysterious world of ice and rock.

Jupiter

The Jovian cloudscape boasts the most spectacular light show in the solar system, with northern and southern lights to dazzle even the most jaded space traveler. Jupiter’s auroras are hundreds of times more powerful than Earth’s, and they form a glowing ring around each pole that’s bigger than our home planet. 

Enceladus

The discovery of Enceladus’ icy jets and their role in creating Saturn’s E-ring is one of the top findings of the Cassini mission to Saturn. Further Cassini discoveries revealed strong evidence of a global ocean and the first signs of potential hydrothermal activity beyond Earth – making this tiny Saturnian moon one of the leading locations in the search for possible life beyond Earth.

Titan

Frigid and alien, yet similar to our own planet billions of years ago, Saturn’s largest moon, Titan has a thick atmosphere, organic-rich chemistry and surface shaped by rivers and lakes of liquid ethane and methane. Our Cassini orbiter was designed to peer through Titan’s perpetual haze and unravel the mysteries of this planet-like moon.

Europa

Astonishing geology and the potential to host the conditions for simple life making Jupiter’s moon Europa a fascinating destination for future exploration. Beneath its icy surface, Europa is believed to conceal a global ocean of salty liquid water twice the volume of Earth’s oceans. Tugging and flexing from Jupiter’s gravity generates enough heat to keep the ocean from freezing.

Innovation at 100

Air travel, spaceflight, robotic solar-system missions: science fiction to those alive at the turn of the 20th century became science fact to those living in the 21st. 

America’s aerospace future has been literally made at our Langley Research Center by the best and brightest the country can offer. Here are some of the many highlights from a century of ingenuity and invention.

Making the Modern Airplane

In times of peace and war, Langley helped to create a better airplane, including unique wing shapes, sturdier structures, the first engine cowlings, and drag cleanup that enabled the Allies to win World War II.

In 1938 Langley mounted the navy's Brewster XF2A-1 Buffalo in the Full-Scale Tunnel for drag reduction studies.

Wind Goes to Work

Langley broke new ground in aeronautical research with a suite of first-of-their-kind wind tunnels that led to numerous advances in commercial, military and vertical flight, such as helicopters and other rotorcraft.

Tracking Earth from Aloft

Development by Langley of a variety of satellite-borne instrumentation has enabled real-time monitoring of planet-wide atmospheric chemistry, air quality, upper-atmosphere ozone concentrations, the effects of clouds and air-suspended particles on climate, and other conditions affecting Earth’s biosphere.

Crucial Shuttle Contributions

Among a number of vital contributions to the creation of the U.S. fleet of space shuttles, Langley developed preliminary shuttle designs and conducted 60,000 hours of wind tunnel tests to analyze aerodynamic forces affecting shuttle launch, flight and landing.

Space Station Research: Air and Space Science

Each month, we highlight a different research topic on the International Space Station. In June, our focus is Air and Space Science.

How is the space station being used to study space? Studies in fundamental physics address space, time, energy and the building blocks of matter. Recent astronomical observation and cosmological models strongly suggest that dark matter and dark energy, which are entities not directly observed and completely understood, dominate these interactions at the largest scales.

The space station provides a modern and well-equipped orbiting laboratory for a set of fundamental physics experiments with regimes and precision not achievable on the ground. 

For example, the CALorimetric Electron Telescope (CALET) is an astrophysics mission that searches for signatures of dark matter (pictured above). It can observe discrete sources of high energy particle acceleration in our local region of the galaxy. 

How is the space station contributing to aeronautics? It provides a long-duration spaceflight environment for conducting microgravity physical science research. This environment greatly reduces buoyancy-driven convection and sedimentation in fluids. By eliminating gravity, space station allows scientists to advance our knowledge in fluid physics and materials science that could lead to better designated air and space engines; stronger, lighter alloys; and combustion processes that can lead to more energy-efficient systems.

How is the space station used to study air? The Cloud-Aerosol Transport System (CATS) is a laster remote-sensing instrument, or lidar, that measures clouds and tiny aerosol particles in the atmosphere such as pollution, mineral dust and smoke. These atmospheric components play a critical part in understanding how human activities such as fossil fuel burning contribute to climate change.

The ISS-RapidScat is an instrument that monitors winds for climate research, weather predictions and hurricane monitoring from the International Space Station.

Earth’s Land Ice by the Numbers

“At a glacial pace” used to mean moving so slowly the movement is almost imperceptible. Lately though, glaciers are moving faster. Ice on land is melting and flowing, sending water to the oceans, where it raises sea levels.

In 2018, we launched the Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) to continue a global record of ice elevation. Now, the results are in. Using millions of measurements from a laser in space and quite a bit of math, researchers have confirmed that Earth is rapidly losing ice.

16 Years 

ICESat-2 was a follow-up mission to the original ICESat, which launched in 2003 and took measurements until 2009. Comparing the two records tells us how much ice sheets have lost over 16 years.

½ Inch

During those 16 years, melting ice from Antarctica and Greenland was responsible for just over a half-inch of sea level rise. When ice on land melts, it eventually finds its way to the ocean. The rapid melt at the poles is no exception.

400,000 Olympic Swimming Pools

One gigaton of ice holds enough water to fill 400,000 Olympic swimming pools. It’s also enough ice to cover Central Park in New York in more than 1,000 feet of ice.

200 Gigatons

Between 2003 and 2019, Greenland lost 200 gigatons of ice per year. That’s 80 million Olympic swimming pools reaching the ocean every year, just from Greenland alone.

118 Gigatons

During the same time period, Antarctica lost 118 gigatons of ice per year. That’s another 47 million Olympic swimming pools every year. While there has been some elevation gain in the continent’s center from increased snowfall, it’s nowhere near enough to make up for how much ice is lost to the sea from coastal glaciers.

10,000 Pulses

ICESat-2 sends out 10,000 pulses of laser light a second down to Earth’s surface and times how long it takes them to return to the satellite, down to a billionth of a second. That’s how we get such precise measurements of height and changing elevation.

These numbers confirm what scientists have been finding in most previous studies and continue a long record of data showing how Earth’s polar ice is melting. ICESat-2 is a key tool in our toolbox to track how our planet is changing.

I was looking at the GLOBE Observer experiments for citizens and was wondering how the eclipse affects the cloud type? Or, I guess, why is that an important thing to measure? Thank you for answering our questions!

As my dad likes to say, I went to college to take up space, so I’m not sure what happens in the atmosphere. However, I think that the atmospheric scientists are interested in the types of waves that will be set up by the temperature gradients generated by the eclipse. So as totality occurs you get a very fast temperature drop in a localized area. I believe this can set up strong winds which may affect the type of clouds and/or their shapes. This is going to be the best-observed eclipse! And one thing I’ve learned as a scientist is that you never know what you’ll find in your data so collect as much of it as possible even if you aren’t sure what you’ll find. That is sometimes when you get the most exciting results! Thanks for downloading the app and helping to collect the data!

6 Ways You Are Safer Thanks to NASA Technology

By now everyone knows that we are to thank for the memory foam in your mattress and the camera in your cell phone. (Right? Right.)

But our technology is often also involved behind the scenes—in ways that make the products we use daily safer and stronger, and in some cases, that can even save lives.

Here are some examples from this year’s edition of Spinoff, our yearly roundup of “space in your life”:

Impact Testing

What happens to your car bumper in an accident? When does it crumple and when does it crack? And are all bumpers coming off the assembly line created equal?

These types of questions are incredibly important when designing a safe car, and one technology that helps almost every U.S. automobile manufacturer find answers is something we helped develop when we had similar questions about the Space Shuttle.

Before flying again after the Columbia disaster in 2003, we had to be sure we understood what went wrong and how to prevent it from ever happening again. We worked with Trilion, Inc. to develop a system using high-speed cameras and software to analyze every impact—from the one that actually happened on the Shuttle to any others we could imagine—and design fixes.

Finding Survivors

We’re pretty good at finding things you can’t see with the naked eye—from distant exoplanets to water on Mars.

But there are also plenty of uses for that know-how on Earth.

One example that has already saved lives: locating heartbeats under debris.

Engineers at our Jet Propulsion Laboratory adapted technology first devised to look for gravity fluctuations to create FINDER, which stands for Finding Individuals for Disaster and Emergency Response and can detect survivors through dense rubble.

We have licensed the technology to two companies, including R4, and it has already been used in natural disaster responses, including after earthquakes in Nepal, Mexico City, Ecuador, and after Hurricane Maria in Puerto Rico.

Fighting Forest Fires

As we have seen this year with devastating wildfires in California, forest fires can spread incredibly quickly.

Knowing when to order an evacuation, where to send firefighters, and how to make every other decision—all amid a raging inferno—depends on having the most up-to-date information as quickly as possible.

Using our expertise in remote sensing and communicating from space, we helped the U.S. Forest Service make its process faster and more reliable, so the data from airborne sensors gets to decision makers on the front line and at the command center in the blink of an eye.

Safer, Germ-Free Ambulances 

When paramedics come racing into a home, the last thing anybody is worrying about is where the ambulance was earlier that morning. A device we helped create ensures you won’t have to.

AMBUstat creates a fog that sterilizes every surface in an ambulance in minutes, so any bacteria, viruses or other contaminants won’t linger on to infect the next patient.

This technology works its magic through the power of atomic oxygen—the unpaired oxygen atoms that are common in the upper reaches of Earth’s atmosphere. We’ve had to learn about these atoms to devise ways to ensure they won’t destroy our spacecraft or harm astronauts, but here, we were able to use that knowledge to direct that destructive power at germs.

Air Filters 

Did you know the air we breathe inside buildings is often up to 10 times more polluted than the air outdoors?

Put the air under a microscope and it’s not pretty, but a discovery we made in the 1990s can make a big impact.

We were working on a way to clear a harmful chemical that accumulates around plants growing on a spacecraft, and it turned out to also neutralize bacteria, viruses, and mold and eliminate volatile organic compounds.

Now air purifiers using this technology are deployed in hospital operating rooms, restaurant kitchens, and even major baseball stadiums to improve air quality and keep everyone healthier. Oh, and you can buy one for your house, too.

Driverless Cars 

Car companies are moving full-speed ahead to build the driverless cars of the not-so-distant future. Software first created to help self-learning robots navigate on Mars may help keep passengers and pedestrians safer once those cars hit the road. The software creates an artificially intelligent “brain” for a car (or drone, for that matter) that can automatically identify and differentiate between cars, trucks, pedestrians, cyclists, and more, helping ensure the car doesn’t endanger any of them. 

So, now that you know a few of the spinoff technologies that we helped develop, you can look for them throughout your day. Visit our page to learn about more spinoff technologies: https://spinoff.nasa.gov Make sure to follow us on Tumblr for your regular dose of space: http://nasa.tumblr.com.
