NASA’s View Of COVID-19

For the Benefit of All: Assistive Tech Developed from NASA Tech

What do modern cochlear implants and robotic gloves have in common? They were derived from NASA technology. We’ve made it easier to find and use our patented inventions that could help create products that enhance life for people with disabilities.

October is National Disability Employment Awareness Month, which highlights the contributions of American workers with disabilities – many of whom use assistive technology on the job. Take a look at these assistive technologies that are NASA spinoffs.

Low-Vision Headsets

The Joint Optical Reflective Display (JORDY) device is a headset that uses NASA image processing and head-mounted display technology to enable people with low vision to read and write. JORDY enhances individuals’ remaining sight by magnifying objects up to 50 times and allowing them to change contrast, brightness, and display modes. JORDY's name was inspired by Geordi La Forge, a blind character from “Star Trek: The Next Generation” whose futuristic visor enabled him to see.

Cochlear Implants

Work that led to the modern cochlear implant was patented by a NASA engineer in the 1970s. Following three failed corrective surgeries, Adam Kissiah combined his NASA electronics know-how with research in the Kennedy Space Center technical library to build his own solution for people with severe-to-profound hearing loss who receive little or no benefit from hearing aids. Several companies now make the devices, which have been implanted in hundreds of thousands of people around the world.

Robotic Gloves

Ironhand, from Swedish company Bioservo Technologies, is the world’s first industrial-strength robotic glove for factory workers and others who perform repetitive manual tasks. It helps prevent stress injuries but has been especially warmly received by workers with preexisting hand injuries and conditions. The glove is based on a suite of patents for the technology developed by NASA and General Motors to build the hands of the Robonaut 2 humanoid robotic astronaut.

Smart Glasses

Neurofeedback technology NASA originally developed to improve pilots’ attention has been the basis for products aimed at helping people manage attention disorders without medication. The devices measure brainwave output to gauge attention levels according to the “engagement index” a NASA engineer created. Then, they show the results to users, helping them learn to voluntarily control their degree of concentration. One such device is a pair of smart glasses from Narbis, whose lenses darken as attention wanes.

Anti-Gravity Treadmills

A NASA scientist who developed ways to use air pressure to simulate gravity for astronauts exercising in space had the idea to apply the concept for the opposite effect on Earth. After licensing his technology, Alter-G Inc. developed its anti-gravity G-Trainer treadmill, which lets users offload some or all of their weight while exercising. The treadmills can help people recover from athletic or brain injuries, and they allow a safe exercise regimen for others with long-term conditions such as arthritis.

Wireless Muscle Sensors

Some of the most exciting assistive technologies to spin off may be yet to come. Delsys Inc. developed electromyographic technology to help NASA understand the effects of long-term weightlessness on astronauts’ muscles and movements. Electromyography detects and analyzes electrical signals emitted when motor nerves trigger movement. Among the company’s customers are physical therapists developing exercise routines to help patients recover from injuries. But some researchers are using the technology to attempt recoveries that once seemed impossible, such as helping paralyzed patients regain movement, letting laryngectomy patients speak, and outfitting amputees with artificial limbs that work like the real thing.  

To further enhance the lives of people with disabilities, NASA has identified a selection of patented technologies created for space missions that could spur the next generation of assistive technology here on Earth.

Things You Might Not Know About Our Sun

The sun is a star, a hot ball of glowing gases at the heart of our solar system. Its influence extends far beyond the orbits of distant Neptune and Pluto. Without the sun’s intense energy and heat, there would be no life on Earth. And though it is special to us, there are billions of stars like our sun scattered across the Milky Way galaxy.

Impress Your Friends with These Sun Facts:

If the sun were as tall as a typical front door, the Earth would be the size of a U.S. nickel

The temperature at the sun’s core is about 27 million degrees Fahrenheit

Our sun is more massive than the average star in its neighborhood. Nearly 90% of stars are less massive, making them cooler and dimmer

The sun contains 99.9% of all matter in our solar system

During a single second, the sun converts 4 million tons of matter to pure energy

It would take about 1 million Earths to fill the sun if it were a hollow ball

The sun rotates on its axis approximately once every 27 days

The sun is 93 million miles away from Earth and is almost 5 billion years old

New Science from our Mission to Touch the Sun

In August 2018, our Parker Solar Probe mission launched to space, soon becoming the closest-ever spacecraft from the Sun. Now, scientists have announced their first discoveries from this exploration of our star!

The Sun may look calm to us here on Earth, but it's an active star, unleashing powerful bursts of light, deluges of particles moving near the speed of light and billion-ton clouds of magnetized material. All of this activity can affect our technology here on Earth and in space.

Parker Solar Probe's main science goals are to understand the physics that drive this activity — and its up-close look has given us a brand-new perspective. Here are a few highlights from what we've learned so far.

1. Surprising events in the solar wind

The Sun releases a continual outflow of magnetized material called the solar wind, which shapes space weather near Earth. Observed near Earth, the solar wind is a relatively uniform flow of plasma, with occasional turbulent tumbles. Closer to the solar wind's source, Parker Solar Probe saw a much different picture: a complicated, active system. 

One type of event in particular drew the eye of the science teams: flips in the direction of the magnetic field, which flows out from the Sun, embedded in the solar wind. These reversals — dubbed "switchbacks" — last anywhere from a few seconds to several minutes as they flow over Parker Solar Probe. During a switchback, the magnetic field whips back on itself until it is pointed almost directly back at the Sun.

The exact source of the switchbacks isn't yet understood, but Parker Solar Probe's measurements have allowed scientists to narrow down the possibilities — and observations from the mission's 21 remaining solar flybys should help scientists better understand these events. 

2. Seeing tiny particle events

The Sun can accelerate tiny electrons and ions into storms of energetic particles that rocket through the solar system at nearly the speed of light. These particles carry a lot of energy, so they can damage spacecraft electronics and even endanger astronauts, especially those in deep space, outside the protection of Earth's magnetic field — and the short warning time for such particles makes them difficult to avoid.

Energetic particles from the Sun impact a detector on ESA & NASA's SOHO satellite.

Parker Solar Probe's energetic particle instruments have measured several never-before-seen events so small that all trace of them is lost before they reach Earth. These instruments have also measured a rare type of particle burst with a particularly high number of heavier elements — suggesting that both types of events may be more common than scientists previously thought.

3. Rotation of the solar wind

Near Earth, we see the solar wind flowing almost straight out from the Sun in all directions. But the Sun rotates as it releases the solar wind, and before it breaks free, the wind spins along in sync with the Sun's surface. For the first time, Parker was able to observe the solar wind while it was still rotating – starting more than 20 million miles from the Sun.

The strength of the circulation was stronger than many scientists had predicted, but it also transitioned more quickly than predicted to an outward flow, which helps mask the effects of that fast rotation from the vantage point where we usually see them from, near Earth, about 93 million miles away. Understanding this transition point in the solar wind is key to helping us understand how the Sun sheds energy, with implications for the lifecycles of stars and the formation of protoplanetary disks.

4. Hints of a dust-free zone

Parker also saw the first direct evidence of dust starting to thin out near the Sun – an effect that has been theorized for nearly a century, but has been impossible to measure until now. Space is awash in dust, the cosmic crumbs of collisions that formed planets, asteroids, comets and other celestial bodies billions of years ago. Scientists have long suspected that, close to the Sun, this dust would be heated to high temperatures by powerful sunlight, turning it into a gas and creating a dust-free region around the Sun.

For the first time, Parker's imagers saw the cosmic dust begin to thin out a little over 7 million miles from the Sun. This decrease in dust continues steadily to the current limits of Parker Solar Probe's instruments, measurements at a little over 4 million miles from the Sun. At that rate of thinning, scientists expect to see a truly dust-free zone starting a little more than 2-3 million miles from the Sun — meaning the spacecraft could observe the dust-free zone as early as 2020, when its sixth flyby of the Sun will carry it closer to our star than ever before.

These are just a few of Parker Solar Probe's first discoveries, and there's plenty more science to come throughout the mission! For the latest on our Sun, follow @NASASun on Twitter and NASA Sun Science on Facebook.

How visible will the stars be compared to a normal night sky if I'm in the path of totality? (Sun completely covered)

I’m not entirely sure, but you will be able to see some stars that you normally wouldn’t see. https://eclipse2017.nasa.gov/sites/default/files/publications/Eclipse_brochure-bookmark_508.pdf In fact, during the 1919 eclipse, Sir Arthur Eddington and others used our ability to see stars close to the Sun during the eclipse to help confirm Einstines’ theory of general relativity. https://eclipse2017.nasa.gov/testing-general-relativity

6 Ways Earth Observations Tackle Real-World Problems

This summer, 30 research projects were launched by recent college graduates and early career professionals as part of our DEVELOP program. The aim is to use our satellite observations of Earth to address an environmental or public policy issue. And they have just 10 weeks to do it! On Aug. 10, 2016, the “DEVELOPers” gathered at our Headquarters in Washington, DC to showcase their results. So, how can Earth observations solve real-world problems? Let’s take a look:

1. They help land managers identify the locations of invasive species.

Austin Haney, DEVELOP project co-lead at University of Georgia, has seen first-hand how an invasive species can affect the ecosystem of Lake Thurmond, a large reservoir that straddles the border between Georgia and South Carolina. Birds in the area “behave visibly different,” he said, after they consume a toxic cyanobacteria that lives on Hydrilla verticillata, an invasive aquatic plant. Ingesting the toxin causes a neurodegenerative disease and ultimately death. Scores of birds have been found dead near lake areas where large amounts of the toxin-supporting Hydrilla grow. To help lake managers better address the situation, Haney and project members developed a tool that uses data from the Landsat 8 satellite to map the distribution of Hydrilla across the lake.

2. They help identify wildlife habitat threatened by wildfires.

Maps that depict habitat and fire risk in eastern Idaho previously stopped short of Craters of the Moon National Monument and Preserve, where shrubs and grasses transition to a sea of ankle-twisting basalt. But the environment is not as inhospitable as it first appears. Throughout the monument there are more than 500 kipukas —pockets of older lava capable of supporting some vegetation. That means it is also prone to burning. Project lead Courtney Ohr explained how her team used data from the Landsat 8 and Sentinel-2 satellites to develop a model that can simulate the area’s susceptibility to wildfires. Decision makers can use this model to monitor the remote wildlife habitat from afar.

3. In conjunction with Instagram, they help find seaweed blooms

Who knew that Instagram could be a tool for science? One DEVELOP team searched for photographs of massive seaweed (sargassum) blooms in the Caribbean, mapped the locations, and then checked what satellites could see. In the process, they tested two techniques for finding algae and floating vegetation in the ocean.

4. They help conserve water by reducing urban stormwater runoff.

Atlanta’s sewer system is among the nation’s most expensive. Yet, the city still struggles with stormwater. It’s an uphill climb as new construction paves over more of the city, hindering its ability to absorb rain. The University of Georgia DEVELOP team partnered with The Nature Conservancy to address the problem.

Using satellite imagery, the team was able to pinpoint areas well-poised to capture more of the city’s runoff. They identified 17 communities ripe for expanding green infrastructure and reforestation. The team used the Land-Use Conflict Identification Strategy and Soil and Water Assessment Tool models and Landsat and Terra satellite data. Their analysis provides local groups with a working picture of the city’s water resources.

5. They show the spread of the mite eating away Puerto Rico’s palm trees.

The red palm mite has devastated Puerto Rico’s trees in recent years. The insect chewed its way through coconut palms, bananas, and plantains on the island in the recent decade. Its spread has hurt crops across the Caribbean.

A DEVELOP team led by Sara Lubkin analyzed satellite imagery to track the mites’ rapid spread from 2002. The team mapped changes to vegetation, such as yellowing, and differences in canopy structure. They made use of imagery from Landsat, Hyperion, IKONOS, and aerial views. Their work can be used to mitigate current mite infestations and monitor and prevent future ones.

6. They evaluate landslide-prone areas in the developing world

One team of DEVELOPers took on several projects to aid people in developing nations. This team from Alabama examined satellite imagery to find past landslides in the African nation of Malawi. Factors such as flooding after long periods of drought have made the country increasingly prone to landslides. Blending maps of the landscape, rainfall data, and population centers, the young researchers assessed the areas most at risk—and most in need of education and support—from landslides.

On Monday, August 21, 2017, our nation will be treated to a total eclipse of the Sun. The eclipse will be visible – weather permitting – across all of North America. The entire continent will experience at least a partial eclipse lasting two to three hours. Halfway through the event, anyone within a 60 to 70 mile-wide path from Oregon to South Carolina will experience a total eclipse. During those brief moments when the moon completely blocks the Sun's bright face for 2+ minutes, day will turn into night, making visible the otherwise hidden solar corona, the Sun's outer atmosphere. Bright stars and planets will become visible as well. This is truly one of nature's most awesome sights. The eclipse provides a unique opportunity to study the Sun, Earth, Moon and their interaction because of the eclipse's long path over land coast to coast.

Scientists will be able to take ground-based and airborne observations over a period of about 90 minutes to complement the wealth of data provided by NASA assets.

5 Myths About Becoming an Astronaut

Editor’s Note: This post was updated on March 15, 2024, to reflect new URLs and updated qualifications for applicants.

Have you ever wondered if you have what it takes to become a NASA astronaut? The term “astronaut” derives from the Greek word meaning “star sailor.”

We’re looking for a new class of astronauts to join the NASA team, and if you’re thinking about applying, there are a few things you should know.

Here are a few myths about becoming an astronaut:

MYTH: All astronauts have piloting experience.

FACT: You don’t need to be a pilot to be an astronaut. Flying experience is not a requirement, but it could be beneficial to have.

MYTH: All astronauts have perfect vision.

FACT: It’s OK if you don’t have 20/20 vision. As of September 2007, corrective surgical procedures of the eye (PRK and LASIK), are now allowed, providing at least one year has passed since the date of the procedure with no permanent adverse aftereffects.

MYTH: All astronauts have advanced degrees, like a PhD.

FACT: While a master’s degree from an accredited university is typically necessary to become an astronaut, an exception exists if you have completed a medical degree or test pilot school.

MYTH: Astronauts are required to have military experience to be selected.

FACT: Military experience is not required to become an astronaut.

MYTH: You must be a certain age to be an astronaut. 

FACT: There are no age restrictions. Astronaut candidates selected in the past have ranged between the ages of 26 and 46, with the average age being 34.

OK, but what are the requirements?

Basic Qualification Requirements

Applicants must meet the following minimum requirements before submitting an application:

Be a U.S. citizen.

Have completed a master’s degree (or foreign equivalent) in an accredited college or university with major study in an appropriate technical field of engineering, biological science, physical science, computer science, or mathematics.

The master’s degree requirement can also be met by having:

Completed at least two years (36 semester hours or 54 quarter hours) in an accredited PhD or related doctoral degree program (or foreign equivalent) with major study in an appropriate technical field of engineering, biological science, physical science, computer science, or mathematics.

Completed a Doctor of Medicine, Doctor of Osteopathic Medicine, or related medical degree (or foreign equivalent) in an accredited college or university.

Completed or be currently enrolled in a Test Pilot School (TPS) program (nationally or internationally recognized) and will have completed this program by June 2025. (Must submit proof of completion or enrollment.)

If TPS is your only advanced technical degree, you must have also completed a bachelor’s degree or higher (or foreign equivalent) at an accredited college or university with major study in an appropriate technical field of engineering, biological science, physical science, computer science, or mathematics.

Have at least three years of related professional experience obtained after degree completion (or 1,000 Pilot-in-Command hours with at least 850 of those hours in high-performance jet aircraft for pilots). For medical doctors, time in residency can count toward experience and must be completed by June 2025.

Be able to pass the NASA long-duration flight astronaut physical.

Benefits To Humanity

How does research in space help life on Earth? That’s a great question! It seems crazy that a laboratory orbiting about 200 miles over us can have a benefits on science on the ground. Here are a few ways that research aboard the International Space Station benefits humanity:

Improve Human Health

The space station has supported research that supports areas such as aging, trauma, disease and the environment. Advances in human health have been gained from the unique microgravity environment.

For example, crew aboard the station experience issues such as bone loss while in space. Learning about the causes and understanding the treatments can help the elderly or people prone to Osteoporosis here on Earth.

Are you Asthmatic? Crew aboard the space station use a tool that could be used for Asthma patients. The lightweight, easy-to-use device is used to monitor levels of asthma control and the efficiency of medication. This leads to more accurate dosing, reduced attacks and improved quality of life.

Drinkable water on the space station isn’t something just sitting in water bottles waiting to be consumed. Since storage and weight are limited in transporting things to space, crew members must recycle old, dirty water and reuse it day after day. The technology they use for this on the space station, can also be used in at-risk areas on Earth that don’t have access to clean water.

Earth Observations

The International Space Station has a unique vantage point for observing Earth’s ecosystems. A wide variety of payloads can be attached to the station’s exterior to collect data on things like: global climate, environmental change and natural hazards.

Farming from Space

Farmers can leverage images from the International Space Station to grow crops. The camera captures frequent images of Earth in visible and infrared light, that helps farmers monitor crop growth for disease or fertility differences.

From NASA to Napa. Some of the research on the space station has even provided benefits to the wine industry on Earth! Solutions for growing crops in space translates really well to solutions for mold prevention in wine cellars and other confined spaces on Earth.

Five NASA Technologies at the 2017 Consumer Electronics Show

This week, we’re attending the International Consumer Electronics Show (CES), where we’re joining industrial pioneers and business leaders from across the globe to showcase our space technology. Since 1967, CES has been the place to be for next-generation innovations to get their marketplace debut.

Our technologies are driving exploration and enabling the agency’s bold new missions to extend the human presence beyond the moon, to an asteroid, to Mars and beyond. Here’s a look at five technologies we’re showing off at #CES2017:

1. IDEAS

Our Integrated Display and Environmental Awareness System (IDEAS) is an interactive optical computer that works for smart glasses. The idea behind IDEAS is to enhance real-time operations by providing augmented reality data to field engineers here on Earth and in space. 

This device would allow users to see and modify critical information on a transparent, interactive display without taking their eyes or hands off the work in front of them. 

This wearable technology could dramatically improve the user’s situational awareness, thus improving safety and efficiency. 

For example, an astronaut could see health data, oxygen levels or even environmental emergencies like “invisible” ethanol fires right on their helmet view pane. 

And while the IDEAS prototype is an innovative solution to the challenges of in-space missions, it won’t just benefit astronauts—this technology can be applied to countless fields here on Earth.

2. VERVE

Engineers at our Ames Research Center are developing robots to work as teammates with humans. 

They created a user interface called the Visual Environment for Remote Virtual Exploration (VERVE) that allows researchers to see from a robot’s perspective. 

Using VERVE, astronauts on the International Space Station remotely operated the K10 rover—designed to act as a scout during NASA missions to survey terrain and collect science data to help human explorers. 

This week, Nissan announced that a version of our VERVE was modified for its Seamless Autonomous Mobility (SAM), a platform for the integration of autonomous vehicles into our society. For more on this partnership: https://www.nasa.gov/ames/nisv-podcast-Terry-Fong

3. OnSight

Did you know that we are leveraging technology from virtual and augmented reality apps to help scientists study Mars and to help astronauts in space? 

The Ops Lab at our Jet Propulsion Laboratory is at the forefront of deploying these groundbreaking applications to multiple missions. 

One project we’re demonstrating at CES, is how our OnSight tool—a mixed reality application developed for the Microsoft HoloLens—enables scientists to “work on Mars” together from their offices. 

Supported by the Mars 2020 and Curiosity missions, it is currently in use by a pilot group of scientists for rover operations. Another HoloLens project is being used aboard the International Space Station to empower the crew with assistance when and where they need it.

At CES, we’re also using the Oculus Rift virtual reality platform to provide a tour from the launchpad at our Kennedy Space Center of our Space Launch System (SLS). SLS will be the world’s most powerful rocket and will launch astronauts in the Orion Spacecraft on missions to an asteroid and eventually to Mars. Engineers continue to make progress aimed toward delivering the first SLS rocket to Kennedy in 2018.

4. PUFFER

The Pop-Up Flat Folding Explorer Robot, PUFFER, is an origami-inspired robotic technology prototype that folds into the size of a smartphone. 

It is a low-volume, low-cost enhancement whose compact design means that many little robots could be packed in to a larger “parent” spacecraft to be deployed on a planet’s surface to increase surface mobility. It’s like a Mars rover Mini-Me!

5. ROV-E

Our Remote Operated Vehicle for Education, or ROV-E, is a six-wheeled rover modeled after our Curiosity and the future Mars 2020 Rover. 

It uses off-the-shelf, easily programmable computers and 3D-printed parts. ROV-E has four modes, including user-controlled driving to sensor-based hazard-avoidance and “follow me” modes. ROV-E can answer questions about Mars and follow voice commands.

ROV-E was developed by a team of interns and young, up-and-coming professionals at NASA’s Jet Propulsion Laboratory who wanted to build a Mars rover from scratch to help introduce students and the public to Science, Technology, Engineering & Mathematics (STEM) careers, planetary science and our Journey to Mars.
