All Eyes on Harvey

Our Earth-observing satellites, along with the cameras and crew of the International Space Station, are keeping a watchful eye over Hurricane Harvey as it churns in the Gulf of Mexico. When Hurricane Harvey blows ashore over coastal Texas on Friday night, it will likely be the first major hurricane to make landfall in the United States since 2005.

image

Above is a view of Harvey from NOAA's GOES-East satellite captured on Aug. 25 at 10:07 a.m. EDT (1407 UTC) clearly showing the storm’s eye as Harvey nears landfall in the southeastern coast of Texas. As Hurricane Harvey continued to strengthen, we analyzed the storm’s rainfall, cloud heights and cloud top temperatures. 

image

Above, the Global Precipitation Mission (GPM) core observatory satellite flew almost directly above intensifying Hurricane Harvey on August 24, 2017 at 6:30 p.m. EDT (2230 UTC) and we used the Microwave Imager instrument to peer through dense storm clouds to reveal the location of intense rainfall bands near the center of the hurricane. 

And from the International Space Station, cameras were pointed towards Harvey as the orbiting laboratory passed overhead 250 miles above the Earth. The video above includes views from the space station recorded on August 24, 2017 at 6:15 p.m. Eastern Time.

The National Hurricane Center expects Harvey to be a category 3 storm on the Saffir-Simpson scale—with winds higher than 111 miles (179 kilometers) per hour—when it makes landfall. It will likely produce a storm surge of 6 to 12 feet (2 to 4 meters) and drop between 15 and 25 inches (38 and 63 centimeters) of rain in some areas—enough to produce life-threatening flash floods.

For updated forecasts, visit the National Hurricane Center.  Ensure you are prepared for Hurricanes. Get tips and more at  FEMA’s Ready site. Get the latest updates from NASA satellites by visiting our Hurricane site.

Pluto Continues to Amaze

image

This dwarf planet sure knows how to get a BIG reaction because we’re stunned by the latest images from our New Horizons spacecraft!

Back on July 14, the spacecraft completed it’s historic Pluto flyby, and is now in an intensive downlink phase. During this time, New Horizons will send us some of the best data and images we’ve seen!

These latest images were taken just 15 minutes after New Horizons’ closest approach to Pluto. The spacecraft looked back toward the sun and captured this near-sunset view. Icy mountains, flat plains and the horizon can all be seen in detail.

image

When we take a closer look, these features truly begin to stand out. Mountains up to 11,000 feet high are met by flat icy plains that extend out to Pluto’s horizon. There, more than a dozen layers of haze in the dwarf planet’s atmosphere can be seen. It’s almost as if we’re flying over the surface with the New Horizons spacecraft.

Speaking of flyover, this new animation of Pluto has been created from images returned from the spacecraft this month. This view shows us what it might be like to take an aerial tour through Pluto’s thin atmosphere and soar above the surface. 

These images and videos are not only stunning, but also provide us with important information about the dwarf planet. So far, scientists can tell that the weather changes from day to day on Pluto. These images, combined with others that have been downloaded, provide evidence for a remarkably Earth-like “hydrological” cycle on Pluto.

NASA Spotlight: Astronaut Jonny Kim

NASA Spotlight: Astronaut Jonny Kim

Dr. Jonny Kim was selected by NASA to join the 2017 Astronaut Candidate Class. He reported for duty in August 2017 and having completed the initial astronaut candidate training is now eligible for mission assignments to the International Space Station, the Moon and eventually Mars. A U.S. Navy SEAL, Kim completed more than 100 combat operations. Kim was commissioned as a naval officer through an enlisted-to-officer program and earned his degree in mathematics at the University of San Diego and a doctorate of medicine at Harvard Medical School. Born and raised in Los Angeles, California to Korean-American immigrants, he enjoys spending time with his family, outdoor activities, academic and professional mentoring, strength training and lifelong learning. 

Dr. Kim took some time from his job as a NASA astronaut to answer questions about his life and career! Enjoy: 

Why did you apply to be an astronaut?

For many reasons. I think that humans are natural explorers. There is a calling in all of us to explore the unknown, push the boundaries and redefine what is possible. I’m drawn to the physical and mental challenges of space exploration and the teamwork required to complete such an objective. And finally, the opportunity to do something good for our country, for humanity, and to inspire the next generation of thinkers, leaders, explorers and scientists.

What was your favorite memory from astronaut training?

image

I’m a big believer that people can grow stronger bonds with each other when they succeed through shared hardship. And I think that developing relationships with one another is one of the best ways to forge successful team skills to be successful in any endeavor. With that context, I can tell you that my favorite memory from astronaut training was traversing the deep canyon slots of the Utah Canyon Lands for almost 2 weeks with my classmates. We hiked trails, climbed canyons, swam through deep, dark, cold and murky waters and forged through uncertainty, all while being together. This shared hardship was not only fun, but it helped us grow closer to one another. It’s one of the fondest memories I have when I think about my amazing classmates, and through that shared hardship, I know I can count on any one of my fellow astronauts when the going gets tough.

If you could play any song during launch, what would it be?

Don’t Stop Believin’ by Journey.

What advice would you give to your younger self?

I would tell myself to always follow your passion, never stature or money, because following a life of passion is long-term, sustainable and usually helps others. Be accountable for your mistakes and failures, and maintain the humility to learn from those mistakes and failures. And finally, I would caution myself that all worthwhile goals are difficult to obtain, but with the right attitude and hard work, you can accomplish anything.

How did your time as a Navy Seal impact your astronaut training?

image

Being a Naval Special Warfare Operator taught me that humans are capable of accomplishing ten times what their bodies and mind tell them. I learned there are no limits in life, and the biggest setback one can have is a poor attitude. I learned the value of strong leadership and accountability. I also learned the meaning of sacrifice, hardship, teamwork, love and compassion. All these traits helped me to develop the hard and soft skills required to be an astronaut.

How do we prepare medically for long duration missions? What tools, resources, medications do we anticipate needing, and how do we figure that out?

This is a great question and the answer is evolving. The way we answer this question is by being thoughtful and consulting the medical communities to weigh the pros and cons of every single decision we make regarding this. Mass plays an important factor, so we have to be mindful of everything we bring and how we train for it.

Who was the first person you called after being selected to be an astronaut?

image

It would have been my wife but she was with me when I heard the news. The first person I called was my mom.

What is one item from home that you would bring to space?

A picture of my wife and kids.

What does it mean to you to be part of the Artemis generation of astronauts?

NASA Spotlight: Astronaut Jonny Kim

It means that I have a duty and obligation to serve humanity’s best interests. To explore the unknown, push boundaries and redefine what’s possible. It means I have an immense opportunity to serve as an example and inspiration to our next generation of leaders and explorers. It also means there is a hard road ahead, and when the mission calls for us, we will be ready.

What are three personal items, besides photos of family and friends, that you would bring with you on your first spaceflight?

An automatic watch, because the engineering behind a timepiece is a beautiful thing. An American flag, because I proudly believe and uphold the principles and ideals our country stands for. And finally, a nice journal that I can put handwritten thoughts on.

Thank you for your time, and good luck on your first spaceflight assignment!

Follow Jonny Kim on Twitter and Instagram to keep up with his life as NASA astronaut. 

It’s not too late to APPLY to #BeAnAstronaut! Applications close TOMORROW, March 31.

2000 vs Now: 15 Years of Humans on Space Station

Humans have been living in space aboard the International Space Station 24-7-365 since Nov. 2, 2000. That’s 15 Thanksgivings, New Years, and holiday seasons astronauts have spent away from their families. 15 years of constant support from Mission Control Houston. And 15 years of peaceful international living in space. 

In November 2000, many of us stuck on Earth wished we could join (at least temporarily) the Expedition 1 crew aboard the International Space Station. Floating effortlessly from module to module, looking down on Earth from a breathtaking height of 350 kilometers.... It's a dream come true for innumerable space lovers.

But be careful what you wish for! Living on the Space Station also means hard work, cramped quarters, and... what's that smell? Probably more outgassing from a scientific experiment or, worse yet, a crewmate.

To get a feel of how long ago that was, this is what the world looked like then vs. now:

2000: Eminem released The Real Slim Shady

image

Now: Scott Kelly listens to  Eminem from space as part of his “Songs of a Year In Space” Spotify playlist

image

__________________________________________________

2000: Cell phones were entering the mainstream

image

Now: Astronauts can video chat with their friends and family from space

New Results From Our Juno Mission Suggest The Planet Is Home To “shallow Lightning.” An Unexpected

New results from our Juno mission suggest the planet is home to “shallow lightning.” An unexpected form of electrical discharge, shallow lightning comes from a unique ammonia-water solution. ⁣

⁣It was previously thought that lightning on Jupiter was similar to Earth, forming only in thunderstorms where water exists in all its phases – ice, liquid, and gas. But flashes observed at altitudes too cold for pure liquid water to exist told a different story. This illustration uses data obtained by the mission to show what these high-altitude electrical storms look like. ⁣

Understanding the inner workings of Jupiter allows us to develop theories about atmospheres on other planets and exoplanets! ⁣

At the center of the image is the artist’s illustration of the Psyche asteroid with deep craters and metal all around.

Let's Explore a Metal-Rich Asteroid 🤘

Between Mars and Jupiter, there lies a unique, metal-rich asteroid named Psyche. Psyche’s special because it looks like it is part or all of the metallic interior of a planetesimal—an early planetary building block of our solar system. For the first time, we have the chance to visit a planetary core and possibly learn more about the turbulent history that created terrestrial planets.

Here are six things to know about the mission that’s a journey into the past: Psyche.

At the bottom-right is the metal asteroid with peaks sticking out of the surface. Credit: NASA/JPL-Caltech/Arizona State Univ./Space Systems Loral/Peter Rubin

1. Psyche could help us learn more about the origins of our solar system.

After studying data from Earth-based radar and optical telescopes, scientists believe that Psyche collided with other large bodies in space and lost its outer rocky shell. This leads scientists to think that Psyche could have a metal-rich interior, which is a building block of a rocky planet. Since we can’t pierce the core of rocky planets like Mercury, Venus, Mars, and our home planet, Earth, Psyche offers us a window into how other planets are formed.

ALT text: Artist’s concept of the asteroid Psyche. The darkness of space takes up the entire background with small twinkly stars. Two large craters are at the center of the asteroid. The asteroid is mostly silvery with a few spots of copper on the surface. The word "Illustration" is printed at the bottom to the right of the asteroid. Credit: NASA/JPL-Caltech/ASU/Peter Rubin

2. Psyche might be different than other objects in the solar system.

Rocks on Mars, Mercury, Venus, and Earth contain iron oxides. From afar, Psyche doesn’t seem to feature these chemical compounds, so it might have a different history of formation than other planets.

If the Psyche asteroid is leftover material from a planetary formation, scientists are excited to learn about the similarities and differences from other rocky planets. The asteroid might instead prove to be a never-before-seen solar system object. Either way, we’re prepared for the possibility of the unexpected!

3. Three science instruments and a gravity science investigation will be aboard the spacecraft.

The three instruments aboard will be a magnetometer, a gamma-ray and neutron spectrometer, and a multispectral imager. Here’s what each of them will do:

Magnetometer: Detect evidence of a magnetic field, which will tell us whether the asteroid formed from a planetary body

Gamma-ray and neutron spectrometer: Help us figure out what chemical elements Psyche is made of, and how it was formed

Multispectral imager: Gather and share information about the topography and mineral composition of Psyche

The gravity science investigation will allow scientists to determine the asteroid’s rotation, mass, and gravity field and to gain insight into the interior by analyzing the radio waves it communicates with. Then, scientists can measure how Psyche affects the spacecraft’s orbit.

4. The Psyche spacecraft will use a super-efficient propulsion system.

Psyche’s solar electric propulsion system harnesses energy from large solar arrays that convert sunlight into electricity, creating thrust. For the first time ever, we will be using Hall-effect thrusters in deep space.

Pictured in front of the spacecraft is Lindy Elkins-Tanton, being interviewed by a member of the media at NASA’s Jet Propulsion Laboratory. Credit: NASA/JPL-Caltech

5. This mission runs on collaboration.

To make this mission happen, we work together with universities, and industry and NASA to draw in resources and expertise.

NASA’s Jet Propulsion Laboratory manages the mission and is responsible for system engineering, integration, and mission operations, while NASA’s Kennedy Space Center’s Launch Services Program manages launch operations and procured the SpaceX Falcon Heavy rocket.

Working with Arizona State University (ASU) offers opportunities for students to train as future instrument or mission leads. Mission leader and Principal Investigator Lindy Elkins-Tanton is also based at ASU.

Finally, Maxar Technologies is a key commercial participant and delivered the main body of the spacecraft, as well as most of its engineering hardware systems.

6. You can be a part of the journey.

Everyone can find activities to get involved on the mission’s webpage. There's an annual internship to interpret the mission, capstone courses for undergraduate projects, and age-appropriate lessons, craft projects, and videos.

You can join us for a virtual launch experience, and, of course, you can watch the launch with us on Oct. 12, 2023, at 10:16 a.m. EDT!

For official news on the mission, follow us on social media and check out NASA’s and ASU’s Psyche websites.

Top 5 Technologies Needed for a Spacecraft to Survive Deep Space

When a spacecraft built for humans ventures into deep space, it requires an array of features to keep it and a crew inside safe. Both distance and duration demand that spacecraft must have systems that can reliably operate far from home, be capable of keeping astronauts alive in case of emergencies and still be light enough that a rocket can launch it.

Missions near the Moon will start when the Orion spacecraft leaves Earth atop the world’s most powerful rocket, the Space Launch System. After launch from Kennedy Space Center in Florida, Orion will travel beyond the Moon to a distance more than 1,000 times farther than where the International Space Station flies in low-Earth orbit, and farther than any spacecraft built for humans has ever ventured. To accomplish this feat, Orion has built-in technologies that enable the crew and spacecraft to explore far into the solar system. Let’s check out the top five: 

image

Systems to Live and Breathe

As humans travel farther from Earth for longer missions, the systems that keep them alive must be highly reliable while taking up minimal mass and volume. Orion will be equipped with advanced environmental control and life support systems designed for the demands of a deep space mission. A high-tech system already being tested aboard the space station will remove carbon dioxide (CO2) and humidity from inside Orion. The efficient system replaces many chemical canisters that would consume up to 10 percent of crew livable area. To save additional space, Orion will also have a new compact toilet, smaller than the one on the space station.

Highly reliable systems are critically important when distant crew will not have the benefit of frequent resupply shipments to bring spare parts from Earth. Even small systems have to function reliably to support life in space, from a working toilet to an automated fire suppression system or exercise equipment that helps astronauts stay in shape to counteract the zero-gravity environment. Distance from home also demands that Orion have spacesuits capable of keeping astronaut alive for six days in the event of cabin depressurization to support a long trip home.

image

Proper Propulsion

The farther into space a vehicle ventures, the more capable its propulsion systems need to be in order to maintain its course on the journey with precision and ensure its crew can get home.

Orion’s highly capable service module serves as the powerhouse for the spacecraft and provides propulsion capabilities that enable it to go around the Moon and back on exploration missions. The service module has 33 engines of various sizes. The main engine will provide major in-space maneuvering capabilities throughout the mission such as inserting Orion into lunar orbit and firing powerfully enough to exit orbit for a return trip to Earth. The other 32 engines are used to steer and control Orion on orbit.

In part due to its propulsion capabilities, including tanks that can hold nearly 2,000 gallons of propellant and a back up for the main engine in the event of a failure, Orion’s service module is equipped to handle the rigors of travel for missions that are both far and long. It has the ability to bring the crew home in a variety of emergency situations.

image

The Ability to Hold Off the Heat

Going to the Moon is no easy task, and it’s only half the journey. The farther a spacecraft travels in space, the more heat it will generate as it returns to Earth. Getting back safely requires technologies that can help a spacecraft endure speeds 30 times the speed of sound and heat twice as hot as molten lava or half as hot as the sun.

When Orion returns from the Moon it will be traveling nearly 25,000 mph, a speed that could cover the distance from Los Angeles to New York City in six minutes. Its advanced heat shield, made with a material called AVCOAT, is designed to wear away as it heats up. Orion’s heat shield is the largest of its kind ever built and will help the spacecraft withstand temperatures around 5,000 degrees Fahrenheit during reentry though Earth’s atmosphere.

Before reentry, Orion also will endure a 700-degree temperature range from about minus 150 to 550 degrees Fahrenheit. Orion’s highly capable thermal protection system, paired with thermal controls, will protect it during periods of direct sunlight and pitch black darkness while its crews comfortably enjoy a safe and stable interior temperature of about 77 degrees Fahrenheit.

image

Radiation Protection

As a spacecraft travels on missions beyond the protection of Earth’s magnetic field, it will be exposed to a harsher radiation environment than in low-Earth orbit with greater amounts of radiation from charged particles and solar storms. This kind of radiation can cause disruptions to critical computers, avionics and other equipment. Humans exposed to large amounts of radiation can experience both acute and chronic health problems ranging from near-term radiation sickness to the potential of developing cancer in the long-term.

Orion was designed from the start with built in system-level features to ensure reliability of essential elements of the spacecraft during potential radiation events. For example, Orion is equipped with four identical computers that each are self-checking, plus an entirely different backup computer, to ensure it can still send commands in the event of a disruption. Engineers have tested parts and systems to a high standard to ensure that all critical systems remain operable even under extreme circumstances.

Orion also has a makeshift storm shelter below the main deck of the crew module. In the event of a solar radiation event, we developed plans for crew on board to create a temporary shelter inside using materials on board. A variety of radiation sensors will also be on the spacecraft to help scientists better understand the radiation environment far away from Earth. One investigation, called AstroRad, will fly on Exploration Mission-1 and test an experimental vest that has the potential to help shield vital organs and decrease exposure from solar particle events.

image

Constant Communication and Navigation

Spacecraft venturing far from home go beyond the Global Positioning System (GPS) in space and above communication satellites in Earth orbit. To talk with mission control in Houston, Orion’s communication and navigation systems will switch from our Tracking and Data Relay Satellites (TDRS) system used by the International Space Station, and communicate through the Deep Space Network.

Orion is equipped with backup communication and navigation systems to help the spacecraft stay in contact with the ground and orient itself if its primary systems fail. The backup navigation system, a relatively new technology called optical navigation, uses a camera to take pictures of the Earth, Moon and stars and autonomously triangulate Orion’s position from the photos. Its backup emergency communications system doesn’t use the primary system or antennae for high-rate data transfer.
