10 Questions About The 2017 Astronaut Class

Will there be a livestream to the solar eclipse on the NASA website?

Yup! We’ll have a live stream up https://eclipse2017.nasa.gov/eclipse-live-stream They I believe will also be covering events that are happening across the US. A bunch of my office mates here are going across the US to help with the coverage and to collect data! It should be incredibly exciting! 

Hot & Steamy RS-25 Engine Test

Today, we tested the RS-25 engine at Stennis Space Center in Mississippi, and boy was it hot! Besides the fact that it was a hot day, the 6,000 degree operating temperature of the hot fire test didn’t help things. This engine is one of four that will power the core stage of our Space Launch System (SLS) into deep space and to Mars. Today’s test reached 109% power and burned 150,000 gallons of liquid oxygen and 60,000 gallons of liquid hydrogen. When SLS launches with all 4 of its engines, it will be the most powerful rocket in the world!

This engine was previously used to to fly dozens of successful missions on the space shuttle, so you might be asking, “Why are we spending time testing it again if we already know it’s awesome?” Well, it’s actually really important that we test them specifically for use with SLS for a number of reasons, including the fact that we will be operating at 109% power, vs. the 104% power previously used.

If you missed the 535-second, ground rumbling test today -- you’re in luck. We’ve compiled all the cool stuff (fire, steam & loud noises) into a recap video. Check it out here:

Tools of the Trade: How Parker Solar Probe Will Study the Sun

Our Parker Solar Probe will get closer to the Sun than any spacecraft has ever gone – it will fly right through the Sun's corona, part of the Sun's atmosphere.

This spacecraft is full of cutting-edge technology, from its heat shield down to its guidance and control systems. It also carries four suites of advanced instruments designed to study the Sun in a multitude of ways.  

1. Measuring particles

Two of Parker Solar Probe's instrument suites are focused on measuring particles – electrons and ions – within the corona.

One of these particle-measuring instrument suites is SWEAP (Solar Wind Electrons Alphas and Protons). SWEAP counts the most common particles in the solar wind – the Sun's constant outflow of material – and measures their properties, like velocity, density and temperature. Gathering this information about solar wind particles will help scientists better understand why the solar wind reaches supersonic speeds and exactly which part of the Sun the particles come from.

One instrument in the SWEAP suite is the Solar Probe Cup. Most of the instruments on Parker Solar Probe stay safe and cool in the shadow of the heat shield, but the Solar Probe Cup is one of the few that sticks out. That's so it can capture and measure particles streaming straight out from the Sun, and it had to go through some intense testing to get ready for this position in the Sun's incredibly hot corona.

The ISʘIS suite (pronounced EE-sis, and including the symbol for the Sun in its acronym) also measures particles. ISʘIS is short for Integrated Science Investigation of the Sun, and this instrument suite measures particles that move faster – and therefore have more energy – than the solar wind.

These measurements will help scientists understand these particles' lifecycles – where they came from, how they got to be traveling so fast (these particles can reach speeds more than half the speed of light!) and what path they take as they travel away from the Sun and into interplanetary space.

2. Taking pictures – but not of the Sun's surface.

WISPR (Wide-Field Imager for Parker Solar Probe) has the only two cameras on Parker Solar Probe – but they're not pointed directly at the Sun. Instead, WISPR looks out the side of the spacecraft, in the direction it's traveling, looking at the space Parker Solar Probe is about to fly through. From that vantage point, WISPR captures images of structures within the corona like coronal mass ejections, or CMEs. CMEs are clouds of solar material that occasionally explode from the Sun at millions of miles per hour. Because this solar material is magnetized, CMEs can trigger geomagnetic storms when they reach Earth – which, in turn, can cause effects like auroras and even, in extreme cases, power outages.  

Right now, our observations of events like these come from satellites orbiting near Earth, so WISPR will give us a whole new perspective. And, scientists will be able to combine WISPR's images with Parker Solar Probe's direct particle measurements to get a better idea of how these structures change as they travel.

3. Studying electric & magnetic fields

The FIELDS instrument suite is appropriately named: It's what scientists will use to study the electric and magnetic fields in the corona.

Electric and magnetic fields are key to understanding what happens, not only on the Sun, but throughout space, because they are the primary driver accelerating charged particles. In particular, a process called magnetic reconnection – when magnetic field lines explosively realign, sending particles rocketing away at incredible speeds – is thought to drive solar explosions, as well as space weather effects on Earth, like the aurora.

FIELDS measures electric and magnetic field at high time resolution, meaning it takes lots of measurements in a short amount of time, to track these processes and shed some light on the mechanics underlying the Sun's behavior. FIELDS' measurements are precisely synced up with those of the SWEAP suite (one of the sets of instruments studying particles) so that scientists can match up the immediate effects that electric and magnetic fields have on the material of the solar wind.

Parker Solar Probe launches summer 2018 on its mission to study the Sun. Keep up with the latest on the mission at nasa.gov/solarprobe or follow us on Twitter and Facebook.

How Climate Change Showed Up in 2021

2021 was tied for the sixth-hottest year since modern record keeping began. We work together with the National Oceanic and Atmospheric Administration to track temperatures around the world and study how they change from year to year.

For decades, the overall global temperature has been increasing because of human activities. The last decade has been the warmest on record. Each individual year’s average temperature, however, can be affected by things like ocean circulation, volcanic eruptions, and specific weather events.

For instance, last year we saw the beginning of La Niña – a pattern of cooler waters in the Pacific – that was responsible for slightly cooling 2021’s average temperature. Still, last year continued a long-term trend of global warming.

Globally, Earth’s temperature in 2021 was nearly 2°F warmer than the late 19th Century, for the seventh year in a row.

The Record

Studying 142 Years

Since 1880, we can put together a consistent record of temperatures around the planet and see that it was much colder in the late-19th century. Before 1880, uncertainties in tracking global temperatures are larger. Temperatures have increased even faster since the 1970s, the result of increasing greenhouse gases in the atmosphere.

Tracking Millions of Individual Observations

Our scientists use millions of individual observations of data from more than 20,000 weather stations and Antarctic research stations, together with ship- and buoy-based observations of sea surface temperatures, to track global temperatures.

Reviewing Multiple Independent Records

Our global temperature record – GISTEMP – is one of a number of independent global temperature records, all of which show the same pattern of warming.

The Consequences

Everywhere Experiences Climate Change Differently

As Earth warms, temperature changes occur unevenly around the globe. The Arctic is currently warming about four times faster than the rest of the planet – a process called Arctic amplification. Similarly, urban areas tend to warm faster than rural areas, partly because building materials like asphalt, steel and concrete retain heat.

Droughts and Floods in Warmer Weather

More than 88% of the Western US experienced drought conditions in 2021. At the same time, communities in Western Europe saw two months’ worth of rain in 24 hours, breaking records and triggering flash floods. Because a hotter climate means more water can be carried in the atmosphere, areas like the Western US suffer drought from the increased 'thirstiness' of the atmosphere, while precipitation events can become more extreme as the amount of moisture in the atmosphere rises.

Sea Levels Continue to Rise

Melting ice raises sea levels around the world, as meltwater drains into the ocean. In addition, heat causes the ocean water to expand. From 1993 to today, global mean sea level has been rising around 3.4 millimeters per year. In 2021, sea level data from the recently launched NASA/ESA Sentinel-6 Michael Freilich mission became available to the public.

There is Hope

“This is not good news, but the fact that we are able to track this in real time and understand why it’s changing, and get people to notice why it’s changing and how we can change things to change the next trajectory, that gives me hope. Because we’re not in the dark here. We’re not the dinosaurs who are unaware the comet is coming. We can see the comet coming, and we can act.” – Dr. Gavin Schmidt, director of NASA GISS, where the global temperature record is calculated

Ways NASA Studies the Ocean

We live on a water planet. The ocean covers a huge part of the Earth's surface – earning it the name Blue Marble.

The ocean is one of Earth’s largest ecosystems and helps moderate Earth’s climate. NASA scientists spend a lot of time studying the ocean and how it is changing as Earth’s climate changes.

In the last few years, NASA has launched an array of missions dedicated to studying this precious part of our planet, with more to come. For World Oceans Month, which starts in June, here are new ways NASA studies the ocean.

1. Seeing the colors of the ocean 🎨

A new NASA mission called PACE will see Earth’s oceans in more color than ever before. The color of the ocean is determined by the interaction of sunlight with substances or particles present in seawater.

Scheduled to launch in 2024, PACE will help scientists assess ocean health by measuring the distribution of phytoplankton, tiny plants and algae that sustain the marine food web. PACE will also continue measuring key atmospheric variables associated with air quality and Earth's climate.

2. Surveying surface water around the globe 💧

The SWOT satellite, launched in late 2022, is studying Earth’s freshwater – from oceans and coasts to rivers, lakes and more – to create the first global survey of Earth’s surface water.

SWOT is able to measure the elevation of water, observing how major bodies of water are changing and detecting ocean features. The data SWOT collects will help scientists assess water resources, track regional sea level changes, monitor changing coastlines, and observe small ocean currents and eddies.

3. Setting sail to understand interactions between the ocean and atmosphere 🚢

With research aircraft, a research ship, and autonomous ocean instruments like gliders, NASA’s S-MODE mission is setting sail to study Earth’s oceans up close. Their goal? To understand ocean whirlpools, eddies and currents.

These swirling ocean features drive the give-and-take of nutrients and energy between the ocean and atmosphere and, ultimately, help shape Earth’s climate.

4. Building ocean satellites the size of a shoebox 📦

NASA’s HawkEye instrument collects ocean color data and captures gorgeous images of Earth from its orbit just over 355 miles (575 kilometers) above Earth’s surface. It’s also aboard a tiny satellite measuring just 10cm x 10 cm x 30 cm – about the size of a shoebox!

5. Designing new missions to study Earth’s oceans! 🌊

NASA is currently designing a new space-based instrument called GLIMR that will help scientists observe and monitor oceans throughout the Gulf of Mexico, the southeastern U.S. coastline and the Amazon River plume that stretches to the Atlantic Ocean. GLIMR will also provide important information about oil spills, harmful algae blooms, water quality and more to local agencies.

6. Taking the ocean to new heights ⬆️

The U.S.-European Sentinel-6 Michael Freilich satellite is helping researchers measure the height of the ocean - a key component in understanding how Earth’s climate is changing.

This mission, which launched in 2020, has a serious job to do. It’s not only helping meteorologists improve their weather forecasts, but it’s helping researchers understand how climate change is changing Earth’s coastlines in real time.

10 Intriguing Worlds Beyond Our Solar System

In celebration of the 20th anniversary of the first confirmed planet around a sun-like star, a collection of some interesting exoplanets has been put together. Some of these are rocky, some are gaseous and some are very, very cold. But there’s one thing each these strange new worlds have in common: All have advanced scientific understanding of our place in the cosmos. Check out these 10 exoplanets, along with artist’s concepts depicting what they might look like. For an extended list of 20 exoplanets, go HERE. 

1. Kepler-186f

Kepler-186f was the first rocky planet to be found within the habitable zone -- the region around the host star where the temperature is right for liquid water. This planet is also very close in size to Earth. Even though we may not find out what’s going on at the surface of this planet anytime soon, it’s a strong reminder of why new technologies are being developed that will enable scientists to get a closer look at distance worlds.

3. Kepler-11 system

This was the first compact solar system discovered by Kepler, and it revealed that a system can be tightly packed, with at least five planets within the orbit of Mercury, and still be stable. It touched off a whole new look into planet formation ideas and suggested that multiple small planet systems, like ours, may be common.

6. CoRoT 7b

The first super-Earth identified as a rocky exoplanet, this planet proved that worlds like the Earth were indeed possible and that the search for potentially habitable worlds (rocky planets in the habitable zone) might be fruitful.

More info

7. Kepler-22b

A planet in the habitable zone and a possible water-world planet unlike any seen in our solar system.

More info

8. Kepler-10b

Kepler's first rocky planet discovery is a scorched, Earth-size world that scientists believe may have a lava ocean on its surface.

More info

9. Kepler-444 system

The oldest known planetary system has five terrestrial-sized planets, all in orbital resonance. This weird group showed that solar systems have formed and lived in our galaxy for nearly its entire existence.

10. 55 Cancri e

Sauna anyone? 55 Cancri e is a toasty world that rushes around its star every 18 hours. It orbits so closely -- about 25 times closer than Mercury is to our sun -- that it is tidally locked with one face forever blistering under the heat of its sun. The planet is proposed to have a rocky core surrounded by a layer of water in a “supercritical” state, where it is both liquid and gas, and then the whole planet is thought to be topped by a blanket of steam.

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.
