Our New Satellite To Study The Edge Of Space

Our New Satellite to Study the Edge of Space

We're about to launch a new satellite called ICON — the Ionospheric Connection Explorer — to study our planet's boundary to space.

image

The overlap between Earth's upper atmosphere and outer space is complicated and constantly changing. It's made up of a mix of neutral gas (like the air we breathe) and charged particles, where negatively charged electrons have separated from positively charged ions. This charged particle soup reacts uniquely to the changing electric and magnetic fields in near-Earth space, while weather conditions from here on Earth can also travel upwards and influence this region. This makes Earth's interface to space a dynamic, hard-to-predict region of the atmosphere.

image

Understanding what causes the changes in this region and how to predict them isn't just a matter of curiosity. Earth's boundary to space is home to many of our Earth-orbiting satellites, and it also plays a role in transmitting signals for communications and navigation systems. Unpredictable changes here can garble those signals and even shorten the lifetime of satellites.

image

ICON, launching on Nov. 7, will study this region with a unique combination of instruments. Orbiting about 360 miles above Earth, ICON will use its cameras to measure winds near the upper edge of Earth’s boundary to space and track atmospheric composition and temperature by studying a phenomenon called airglow. ICON also carries an instrument that will capture and measure the particles directly around the spacecraft, or in situ. 

image

ICON is launching aboard a Northrop Grumman Pegasus XL rocket. On launch day, the Pegasus XL is carried out over the ocean by Northrop Grumman's L-1011 Stargazer aircraft, which takes off from Cape Canaveral Air Force Station in Florida. About 50 miles off the coast of Florida, the Pegasus XL drops from the plane and free-falls for about five seconds before igniting and carrying ICON into low-Earth orbit.

NASA TV coverage of the launch starts at 2:45 a.m. EST on Nov. 7 at nasa.gov/live. You can also follow along with the mission on Twitter, Facebook or at nasa.gov/icon.

🏊‍♂️ Down For A Dip In The Cosmic Reef?

🏊‍♂️ 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.

NASA’s Satellite Data Help Save Lives

For the first time, measurements from our Earth-observing satellites are being used to help combat a potential outbreak of life-threatening cholera. Humanitarian teams in Yemen are targeting areas identified by a NASA-supported project that precisely forecasts high-risk regions based on environmental conditions observed from space.

image

Cholera is caused by consuming food or water contaminated with a bacterium called Vibrio cholerae.

image

The disease affects millions of people every year and can be deadly. It remains a major threat to global health, especially in developing countries, such as Yemen, where access to clean water is limited.

image

To calculate the likelihood of an outbreak, scientists run a computer model that takes satellite observations of things like rain and temperatures and combines them with information on local sanitation and clean water infrastructure. In 2017, the model achieved 92 percent accuracy in predicting the regions where cholera was most likely to occur and spread in Yemen. An outbreak that year in Yemen was the world's worst, with more than 1.1 million suspected cases and more than 2,300 deaths, according to the World Health Organization.

image

International humanitarian organizations took notice. In January 2018, Fergus McBean, a humanitarian adviser with the U.K.'s Department for International Development, read about the NASA-funded team's 2017 results and contacted them with an ambitious challenge: to create and implement a cholera forecasting system for Yemen, in only four months.

“It was a race against the start of rainy season,” McBean said.

The U.S. researchers began working with U.K. Aid, the U.K. Met Office, and UNICEF on the innovative approach to use the model to inform cholera risk reduction in Yemen.

In March, one month ahead of the rainy season, the U.K. international development office began using the model’s forecasts. Early results show the science team’s model predictions, coupled with Met Office weather forecasts, are helping UNICEF and other aid groups target their response to where support is needed most.

“By joining up international expertise with those working on the ground, we have for the very first time used these sophisticated predictions to help save lives and prevent needless suffering,” said Charlotte Watts, chief scientist for United Kingdom’s Department for International Development.

Aboard The International Space Station This Morning, Astronaut Kimiya Yui Of The Japan Aerospace Exploration

Aboard the International Space Station this morning, Astronaut Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) successfully captured JAXA's Kounotori 5 H-II Transfer Vehicle (HTV-5) at 6:28 a.m. EDT.

Yui commanded the station's robotic arm, Canadarm2, to reach out and grapple the HTV-5, while NASA astronauts Kjell Lindgren provided assistance and Scott Kelly monitored HTV-5 systems. The HTV-5 launched aboard an H-IIB rocket at 7:50 a.m. Wednesday, Aug. 19, from the Tanegashima Space Center in southern Japan. Since then, the spacecraft has performed a series of engine burns to fine-tune its course for arrival at the station.

The HTV-5 is delivering more than 8,000 pounds of equipment, supplies and experiments in a pressurized cargo compartment. The unpressurized compartment will deliver the 1,400-pound CALorimetric Electron Telescope (CALET) investigation, an astrophysics mission that will search for signatures of dark matter and provide the highest energy direct measurements of the cosmic ray electron spectrum.

Below is a breathtaking image shared by Astronaut Scott Kelly of the HTV-5 and Canadarm2, which reached out and grappled the cargo spacecraft.

The Special Ingredients…of Earth!

image

With its blue skies, puffy white clouds, warm beaches and abundant life, planet Earth is a pretty special place. A quick survey of the solar system reveals nothing else like it. But how special is Earth, really?

image

One way to find out is to look for other worlds like ours elsewhere in the galaxy. Astronomers using our Kepler Space Telescope and other observatories have been doing just that! 

image

In recent years they’ve been finding other planets increasingly similar to Earth, but still none that appear as hospitable as our home world. For those researchers, the search goes on.

image

Another group of researchers have taken on an entirely different approach. Instead of looking for Earth-like planets, they’ve been looking for Earth-like ingredients. Consider the following:

image

Our planet is rich in elements such as carbon, oxygen, iron, magnesium, silicon and sulfur…the stuff of rocks, air, oceans and life. Are these elements widespread elsewhere in the universe? 

image

To find out, a team of astronomers led by the Japanese Aerospace Exploration Agency (JAXA), with our participation, used Suzaku. This Japanese X-ray satellite was used to survey a cluster of galaxies located in the direction of the constellation Virgo.

image

The Virgo cluster is a massive swarm of more than 2,000 galaxies, many similar in appearance to our own Milky Way, located about 54 million light years away. The space between the member galaxies is filled with a diffuse gas, so hot that it glows in X-rays. Instruments onboard Suzaku were able to look at that gas and determine which elements it’s made of.

image

Reporting their findings in the Astrophysical Journal Letters, they reported findings of iron, magnesium, silicon and sulfur throughout the Virgo galaxy cluster. The elemental ratios are constant throughout the entire volume of the cluster, and roughly consistent with the composition of the sun and most of the stars in our own galaxy.

image

When the Universe was born in the Big Bang 13.8 billon years ago, elements heavier than carbon were rare. These elements are present today, mainly because of supernova explosions. 

image

Massive stars cook elements such as, carbon, oxygen, iron, magnesium, silicon and sulfur in their hot cores and then spew them far and wide when the stars explode.

image

According to the observations of Suzaku, the ingredients for making sun-like stars and Earth-like planets have been scattered far and wide by these explosions. Indeed, they appear to be widespread in the cosmos. The elements so important to life on Earth are available on average and in similar relative proportions throughout the bulk of the universe. In other words, the chemical requirements for life are common.

image

Earth is still special, but according to Suzaku, there might be other special places too. Suzaku recently completed its highly successful mission.

What Caused This Outburst Of This Star Named V838 Mon? For Reasons Unknown, This Star’s Outer Surface

What caused this outburst of this star named V838 Mon? For reasons unknown, this star’s outer surface suddenly greatly expanded with the result that it became the brightest star in the entire Milky Way Galaxy in January 2002. Then, just as suddenly, it faded. A stellar flash like this had never been seen before – supernovas and novas expel matter out into space.

Although the V838 Mon flash appears to expel material into space, what is seen in the above GIF from the Hubble Space Telescope is actually an outwardly moving light echo of the bright flash.

In a light echo, light from the flash is reflected by successively more distant rings in the complex array of ambient interstellar dust that already surrounded the star. V838 Mon lies about 20,000 light years away toward the constellation of the unicorn (Monoceros), while the light echo above spans about six light years in diameter.

These 9 Companies Could Help Us Send the Next Robotic Landers to the Moon

We sent the first humans to land on the Moon in 1969. Since then, only of 12 men have stepped foot on the lunar surface – but we left robotic explorers behind to continue gathering science data. And now, we’re preparing to return. Establishing a sustained presence on and near the Moon will help us learn to live off of our home planet and prepare for travel to Mars.

image

To help establish ourselves on and near the Moon, we are working with a few select American companies. We will buy space on commercial robotic landers, along with other customers, to deliver our payloads to the lunar surface. We’re even developing lunar instruments and tools that will fly on missions as early as 2019!

image

Through partnerships with American companies, we are leading a flexible and sustainable approach to deep space missions. These early commercial delivery missions will also help inform new space systems we build to send humans to the Moon in the next decade. Involving American companies and stimulating the space market with these new opportunities to send science instruments and new technologies to deep space will be similar to how we use companies like Northrop Grumman and SpaceX to send cargo to the International Space Station now. These selected companies will provide a rocket and cargo space on their robotic landers for us (and others!) to send science and technology to our nearest neighbor.

So who are these companies that will get to ferry science instruments and new technologies to the Moon?

Here’s a digital “catalogue” of the organizations and their spacecraft that will be available for lunar services over the next decade:

Astrobotic Technology, Inc.

Pittsburg, PA

image

Deep Space Systems

Littleton, CO

image

Firefly Aerospace, Inc.

Cedar Park, TX

image

Intuitive Machines, LLC

Houston, TX

image

Lockheed Martin Space

Littleton, CO

image

Masten Space Systems, Inc.

Mojave, CA

image

Moon Express, Inc.

Cape Canaveral, FL

image

Orbit Beyond, Inc.

Edison, NJ

image

Draper, Inc.

Cambridge, MA

image

We are thrilled to be working with these companies to enable us to investigate the Moon in new ways. In order to expand humanity’s presence beyond Earth, we need to return to the Moon before we go to Mars.

The Moon helps us to learn how to live and work on another planetary body while being only three days away from home – instead of several months. The Moon also holds enormous potential for testing new technologies, like prospecting for water ice and turning it into drinking water, oxygen and rocket fuel. Plus, there’s so much science to be done!

image

The Moon can help us understand the early history of the solar system, how planets migrated to their current formation and much more. Understanding how the Earth-Moon system formed is difficult because those ancient rocks no longer exist here on Earth. They have been recycled by plate tectonics, but the Moon still has rocks that date back to the time of its formation! It’s like traveling to a cosmic time machine!

Join us on this exciting journey as we expand humanity’s presence beyond Earth.

The 2021 Perseid Meteor Shower Is Here!

image

Image Credit: NASA/Bill Ingalls 

The Perseids are at their peak this week!

The Perseid meteor shower, one of the biggest meteor showers of the year, will be at its brightest early in the morning on Thursday, August 12, 2021 and Friday, August 13, 2021. Read on for some tips on how to watch the night sky this week – and to find out: what exactly are the Perseids, anyway?

image

Credit: NASA/Bill Ingalls

Your best chance to spot the Perseids will be between 2 AM and dawn (local time) the morning of August 12 or 13. Find a dark spot, avoid bright lights (yes, that includes your phone) and get acclimated to the night sky.

Your eyes should be at peak viewing capacity after about 30 minutes; with a clear, dark sky, you could see more than 40 Perseids an hour! If you’re not an early bird, you can try and take a look soon after sunset (around 9 PM) on the 12th, though you may not see as many Perseids then.

image

If it’s too cloudy, or too bright, to go skywatching where you are, just stay indoors and watch the Perseids online!

Our Meteor Watch program will be livestreaming the Perseids from Huntsville, Alabama on Facebook (weather permitting), starting around 11 p.m. EDT on August 11 and continuing through sunrise.

So… why are they called the Perseids?

Because all of a meteor shower’s meteors have similar orbits, they appear to come from the same place in the sky – a point called the radiant. 

image

The radiant for the Perseids, as you might guess from the name, is in the constellation Perseus, found near Aries and Taurus in the night sky.

But they’re not actually coming from Perseus, right?

image

Right! The Perseids are actually fragments of the comet Swift-Tuttle, which orbits within our solar system.

If you want to learn more about the Perseids, visit our Watch the Skies blog or check out our monthly “What’s Up” video series. Happy viewing!

Did you ever have insecurities while chasing your goal of becoming an astronaut? Were there pressures placed on you, by yourself or others, that you had to overcome? And if so, how did you overcome them? -Emma

Emma, I think everyone has insecurities about going into the unknown. The trick is not letting them get in the way. I think if you’re passionate about what you want, no amount of insecurities will keep you from it.
