What Would NASA Imagery Experts Pack For The Moon?

Exploring an Asteroid Without Leaving Earth

You may remember that back in February, four crew members lived and worked inside our Human Research Exploration Analog (HERA). That crew, made up of 4 women, simulated a 715-day journey to a Near-Earth asteroid. Then in May, a second crew of 4 – this time, 4 men, launched on their simulated journey to that same asteroid.  These 30 day missions help our researchers learn how isolation and close quarters affect individual and group behavior. Studies like this at our Johnson Space Center prepare us for long duration space missions, like a trip to an asteroid or even to Mars. We now have a third crew, living and working inside the HERA. This is the spacecraft’s 11th crew. The mission began on June 11, and will end on August 10.

The crew members are currently living inside this compact, science-making house. But unlike in a normal house, these inhabitants won’t go outside for 30 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to internet. The only people they will talk with regularly are mission control and each other.

The HERA XI crew is made up of 3 men and 1 woman selected from the Johnson Space Center Test Subject Screening (TSS) pool. The crew member selection process is based on a number of criteria, including the same criteria for astronaut selection. The four would-be astronauts are:

• Tess Caswell

• Kyle Foster

• Daniel Surber

• Emmanuel Urquieta

What will they be doing?

The crew will test hardware prototypes to get “the bugs worked out” before they are used in off-Earth missions. They will conduct experiments involving plants, brine shrimp, and creating a piece of equipment with a 3D printer. After their visit to an asteroid, the crew will simulate the processing of soil and rocks they collected virtually. Researchers outside of the spacecraft will collect data regarding team dynamics, conflict resolution and the effects of extended isolation and confinement.

How real is a HERA mission?

When we set up an analog research investigation, we try to mimic as many of the spaceflight conditions as we can. This simulation means that even when communicating with mission control, there will be a delay on all communications ranging from 1 to 5 minutes each way, depending on how far their simulated spacecraft is from Earth.

Obviously we are not in microgravity, so none of the effects of microgravity on the human or the vehicle can be tested. You can simulate isolation to a great degree – although the crew knows they are note really isolated from humanity, the communications delays and ban from social media help them to suspend reality. We emulate confinement and the stress that goes along with it.

Scientists and researchers use analogs like HERA to gather more data for comparison to data collected aboard the space station and from other analogs so they can draw conclusions needed for a real mission to deep space, and one day for a journey to Mars.            

A few other details:

The crew follows a timeline that is similar to one used for the     ISS crew.

They work 16 hours a day, Monday through Friday. This     includes time for daily planning, conferences, meals and exercises.  

They will be growing and taking care of plants and     brine shrimp, which they will analyze and document.

Past HERA crew members wore a sensor that recorded heart rate, distance, motion and sound intensity. When crew members were working together, the sensor would also record their proximity as well, helping investigators learn about team cohesion.

Researchers also learned about how crew members react to stress by recording and analyzing verbal interactions and by analyzing “markers” in blood and saliva samples.

As with the 2 earlier missions this year, this mission will include 22 individual investigations across key human research elements. From psychological to physiological experiments, the crew members will help prepare us for future missions.

The Shrinking Aral Sea

The Aral Sea was once the fourth-largest lake in the world. Fed primarily by snowmelt and precipitation flowing down from faraway mountains, it was a temperate oasis in an arid region. But in the 1960s, the Soviet Union diverted two major rivers to irrigate farmland, cutting off the inland sea from its source. As the Aral Sea dried up, fisheries collapsed, as did the communities that depended on them. The remaining water supply became increasingly salty and polluted with runoff from agricultural plots. Loss of the Aral Sea's water influenced regional climate, making the winters even colder and the summers much hotter.

While seasonal rains still bring water to the Aral Sea, the lake is roughly one-tenth of its original size. These satellite images show how the Aral Sea and its surrounding landscape has changed over the past few decades.

Pluto the Small Dwarf Planet

Tired of singing the same holiday songs? Here’s a celestial take on the classic Rudolph the Red Nose Reindeer that you can introduce to your friends and family.

(Three infrared wavelength ranges were placed into the three color channels (red, green and blue, respectively) to create this false color Christmas portrait.)

Sung to the tune of Rudolph the Red Nosed Reindeer

Intro You know Mercury, Venus and Earth and Mars, too Jupiter, Saturn, Uranus, and Neptune But do you recall the most famous Solar System body of all

Verse 1 Pluto the small dwarf planet Has a very shiny glow And if you had discovered it Your name might be Clyde Tombaugh

Verse 2 All of the other planets  used to laugh and call him names They never let poor Pluto join in planetary games

Verse 3 Then one fateful summer eve New Horizons came to say “Pluto with your heart so bright Won’t you let me flyby tonight?”

Verse 4 Then all the planets loved him and they shouted out with glee, “NASA!” Pluto the small dwarf planet You’ll go down in history!

(repeat V3 and V4)

This song was written by Andres Almeida, a NASA employee, for a holiday office party. It’s a fun take on the classic Rudolph the Red Nosed Reindeer, with a NASA spin. Enjoy!

How had your background in the US Air Force as a flight test engineer prepare you for the challenges and demands of being an astronaut?

What’s Up for December?

View Mars right now, and prepare for 2016, the best Mars viewing year since 2005! Last month early risers watched small, reddish Mars dance with brighter Jupiter and Venus just before sunrise. 

This month Mars rises earlier-by about 2 a.m. local time. Its reddish color is unmistakable, even without a telescope. It's easy to see below the Moon and Jupiter on December 4. You won't see many features this month, because the planet is almost 10 times smaller than nearby Jupiter appears and 350 times smaller than the Moon appears to us on Earth.

You should also be able to see Mars' north polar region this month, because it's currently tilted towards Earth. 

You'll be amazed at the changes you'll see during 2016. January through December are all prime Mars observing months. Between January and May next year, Mars triples in apparent diameter as its orbit around the sun brings it closer to Earth. You'll even be able to see the areas on Mars where NASA's Mars landers are located.

By October, Mars shrinks in apparent size to less than half its May diameter as it speeds away from Earth. Mars shrinks even further from October through December, returning to the same size we saw in January 2016 by year's end.

So put Mars viewing on your calendar for 2016. You won't see Mars this size again until 2018, when Mars will put on an even better show.

Solar System: Things to Know This Week

Our Psyche mission to a metal world, which will explore a giant metal asteroid known as 16 Psyche, is getting a new, earlier launch date. Psyche is now expected to launch from the Kennedy Space Center in 2022, cruise through the solar system for 4.6 years, and arrive at the Psyche asteroid in 2026, four years earlier than planned. 

Below are 10 things to know about this mission to a completely new and unexplored type of world.

1. Psyche, Squared 

Psyche is the name of the NASA space mission and the name of the unique metal asteroid orbiting the sun between Mars and Jupiter. The asteroid was discovered in 1852 by Italian astronomer Annibale de Gasparis and named after the Greek mythological figure Psyche, whom Cupid fell in love with. "Psyche" in Greek also means "soul."

2. Mission: Accepted

The Psyche Mission was selected for flight earlier this year under NASA's Discovery Program. And it will take a village to pull off: The spacecraft is being built by Space Systems Loral in Palo Alto, California; the mission is led by Arizona State University; and NASA's Jet Propulsion Laboratory will be responsible for mission management, operations and navigation.

3. An Unusual Asteroid 

For the very first time, this mission will let us examine a world made not of rock and ice, but metal. Scientists think Psyche is comprised mostly of metallic iron and nickel, similar to Earth's core - which means Psyche could be an exposed core of an early planet as large as Mars.

4. Sweet 16 

Psyche the asteroid is officially known as 16 Psyche, since it was the 16th asteroid to be discovered. It lies within the asteroid belt, is irregularly shaped, about the size of Massachusetts, and is about three times farther away from the sun than Earth.

5. Discoveries Abound 

The Psyche mission will observe the asteroid for 20 months. Scientists hope to discover whether Psyche is the core of an early planet, how old it is, whether it formed in similar ways to Earth's core, and what its surface is like. The mission will also help scientists understand how planets and other bodies separated into their layers including cores, mantles and crusts early in their histories. "Psyche is the only known object of its kind in the solar system and this is the only way humans will ever visit a core," said Principal Investigator Lindy Elkins-Tanton of Arizona State University.

6. Think Fast 

The mission launch and arrival were moved up because Psyche's mission design team were able to plot a more efficient trajectory that no longer calls for an Earth gravity assist, ultimately shortening the cruise time. The new trajectory also stays farther from the sun, reducing the amount of heat protection needed for the spacecraft, and will still include a Mars flyby in 2023.

7. Gadgets Galore

The Psyche spacecraft will be decked out with a multispectral imager, gamma ray and neutron spectrometer, magnetometer, and X-band gravity science investigation. More: https://sese.asu.edu/research/psyche

8. Stunning Solar Panels 

In order to support the new mission trajectory, the solar array system was redesigned from a four-panel array in a straight row on either side of the spacecraft to a more powerful five-panel x-shaped design, commonly used for missions requiring more capability. Much like a sports car, combining a relatively small spacecraft body with a very high-power solar array design means the Psyche spacecraft will be able to speed to its destination much faster. Check out this artist's-concept illustration here: https://www.nasa.gov/image-feature/artists-concept-of-psyche-spacecraft-with-five-panel-array

9. See For Yourself

Watch the planned Psyche mission in action.

10. Even More Asteroids

Our missions to asteroids began with the orbiter NEAR of asteroid Eros, which arrived in 2000, and continues with Dawn, which orbited Vesta and is now in an extended mission at Ceres. The mission OSIRIS-REx, which launched on Sept. 8, 2016, is speeding toward a 2018 rendezvous with the asteroid Bennu, and will deliver a sample back to Earth in 2023. The Lucy mission is scheduled to launch in October 2021 and will explore six Jupiter Trojan asteroids. More: https://www.jpl.nasa.gov/news/news.php?feature=6713

Rocket Fuel in Her Blood: The Story of JoAnn Morgan

As the Apollo 11 mission lifted off on the Saturn V rocket, propelling humanity to the surface of the Moon for the very first time, members of the team inside Launch Control Center watched through a window.

The room was crowded with men in white shirts and dark ties, watching attentively as the rocket thrust into the sky. But among them sat one woman, seated to the left of center in the third row in the image below. In fact, this was the only woman in the launch firing room for the Apollo 11 liftoff.

This is JoAnn Morgan, the instrumentation controller for Apollo 11. Today, this is what Morgan is most known for. But her career at NASA spanned over 45 years, and she continued to break ceiling after ceiling for women involved with the space program.

“It was just meant to be for me to be in the launching business,” she says. “I’ve got rocket fuel in my blood.”

Morgan was inspired to join the human spaceflight program when Explorer 1 was launched into space in 1958, the first satellite to do so from the United States. Explorer 1 was instrumental in discovering what has become known as the Van Allen radiation belt. 

“I thought to myself, this is profound knowledge that concerns everyone on our planet,” she says. “This is an important discovery, and I want to be a part of this team. I was compelled to do it because of the new knowledge, the opportunity for new knowledge.”

The opportunity came when Morgan spotted an advertisement for two open positions with the Army Ballistic Missile Agency. The ad listed two Engineer’s Aide positions available for two students over the summer.

 “Thank God it said ‘students’ and not ‘boys’” says Morgan, “otherwise I wouldn’t have applied.”

After Morgan got the position, the program was quickly rolled into a brand-new space exploration agency called NASA. Dr. Kurt Debus, the first director of Kennedy Space Center (KSC), looked at Morgan’s coursework and provided Morgan with a pathway to certification. She was later certified as a Measurement and Instrumentation Engineer and a Data Systems Engineer.

There was a seemingly infinite amount of obstacles that Morgan was forced to overcome — everything from obscene phone calls at her station to needing a security guard to clear out the men’s only restroom.

“You have to realize that everywhere I went — if I went to a procedure review, if I went to a post-test critique, almost every single part of my daily work — I’d be the only woman in the room,” reflects Morgan. “I had a sense of loneliness in a way, but on the other side of that coin, I wanted to do the best job I could.”

To be the instrumentation controller in the launch room for the Apollo 11 liftoff was as huge as a deal as it sounds. For Morgan, to be present at that pivotal point in history was ground-breaking: “It was very validating. It absolutely made my career.”

Much like the Saturn V rocket, Morgan’s career took off. She was the first NASA woman to win a Sloan Fellowship, which she used to earn a Master of Science degree in management from Stanford University in California. When she returned to NASA, she became a divisions chief of the Computer Systems division.

From there, Morgan excelled in many other roles, including deputy of Expendable Launch Vehicles, director of Payload Projects Management and director of Safety and Mission Assurance. She was one of the last two people who verified the space shuttle was ready to launch and the first woman at KSC to serve in an executive position, associate director of the center.

To this day, Morgan is still one of the most decorated women at KSC. Her numerous awards and recognitions include an achievement award for her work during the activation of Apollo Launch Complex 39, four exceptional service medals and two outstanding leadership medals. In 1995, she was inducted into the Florida Women's Hall of Fame.

After serving as the director of External Relations and Business Development, she retired from NASA in August 2003.

Today, people are reflecting on the 50th anniversary of Apollo 11, looking back on photos of the only woman in the launch firing room and remembering Morgan as an emblem of inspiration for women in STEM. However, Morgan’s takeaway message is to not look at those photos in admiration, but in determination to see those photos “depart from our culture.”

“I look at that picture of the firing room where I’m the only woman. And I hope all the pictures now that show people working on the missions to the Moon and onto Mars, in rooms like Mission Control or Launch Control or wherever — that there will always be several women. I hope that photos like the ones I’m in don’t exist anymore.”

Solar System: 5 Things To Know This Week

Our solar system is huge, so let us break it down for you. Here are 5 things to know this week: 

1. Make a Wish

The annual Leonids meteor shower is not known for a high number of "shooting stars" (expect as many as 15 an hour), but they're usually bright and colorful. They're fast, too: Leonids travel at speeds of 71 km (44 miles) per second, which makes them some of the fastest. This year the Leonids shower will peak around midnight on Nov. 17-18. The crescent moon will set before midnight, leaving dark skies for watching. Get more viewing tips HERE.

2. Back to the Beginning

Our Dawn mission to the dwarf planet Ceres is really a journey to the beginning of the solar system, since Ceres acts as a kind of time capsule from the formation of the asteroid belt. If you'll be in the Washington DC area on Nov. 19, you can catch a presentation by Lucy McFadden, a co-investigator on the Dawn mission, who will discuss what we've discovered so far at this tiny but captivating world. Find out how to attend HERE. 

3. Keep Your Eye on This Spot

The Juno spacecraft is on target for a July 2016 arrival at the giant planet Jupiter. But right now, your help is needed. Members of the Juno team are calling all amateur astronomers to upload their telescopic images and data of Jupiter. This will help the team plan their observations. Join in HERE.

4. The Ice Volcanoes of Pluto

The more data from July's Pluto flyby that comes down from the New Horizons spacecraft, the more interesting Pluto becomes. The latest finding? Possible ice volcanoes. Using images of Pluto's surface to make 3-D topographic maps, scientists discovered that some mountains on Pluto, such as the informally named Piccard Mons and Wright Mons, had structures that suggested they could be cryovolcanoes that may have been active in the recent geological past.

5. Hidden Storm

Cameras aboard the Cassini spacecraft have been tracking an impressive cloud hovering over the south pole of Saturn's moon Titan. But that cloud has turned out to be just the tip of the iceberg. A much more massive ice cloud system has been found lower in the stratosphere, peaking at an altitude of about 124 miles (200 kilometers).

Tracking the Sun’s Cycles

Scientists just announced that our Sun is in a new cycle.

Solar activity has been relatively low over the past few years, and now that scientists have confirmed solar minimum was in December 2019, a new solar cycle is underway — meaning that we expect to see solar activity start to ramp up over the next several years.

The Sun goes through natural cycles, in which the star swings from relatively calm to stormy. At its most active — called solar maximum — the Sun is freckled with sunspots, and its magnetic poles reverse. At solar maximum, the Sun’s magnetic field, which drives solar activity, is taut and tangled. During solar minimum, sunspots are few and far between, and the Sun’s magnetic field is ordered and relaxed.

Understanding the Sun’s behavior is an important part of life in our solar system. The Sun's violent outbursts can disturb the satellites and communications signals traveling around Earth, or one day, Artemis astronauts exploring distant worlds. Scientists study the solar cycle so we can better predict solar activity.

Measuring the solar cycle

Surveying sunspots is the most basic of ways we study how solar activity rises and falls over time, and it’s the basis of many efforts to track the solar cycle. Around the world, observers conduct daily sunspot censuses. They draw the Sun at the same time each day, using the same tools for consistency. Together, their observations make up the international sunspot number, a complex task run by the World Data Center for the Sunspot Index and Long-term Solar Observations, at the Royal Observatory of Belgium in Brussels, which tracks sunspots and pinpoints the highs and lows of the solar cycle. Some 80 stations around the world contribute their data.

Other indicators besides sunspots can signal when the Sun is reaching its low. In previous cycles, scientists have noticed the strength of the Sun’s magnetic field near the poles at solar minimum hints at the intensity of the next maximum. When the poles are weak, the next peak is weak, and vice versa.

Another signal comes from outside the solar system. Cosmic rays are high-energy particle fragments, the rubble from exploded stars in distant galaxies that shoot into our solar system with astounding energy. During solar maximum, the Sun’s strong magnetic field envelops our solar system in a magnetic cocoon that is difficult for cosmic rays to infiltrate. In off-peak years, the number of cosmic rays in the solar system climbs as more and more make it past the quiet Sun. By tracking cosmic rays both in space and on the ground, scientists have yet another measure of the Sun’s cycle.

Since 1989, an international panel of experts—sponsored by NASA and NOAA—meets each decade to make their prediction for the next solar cycle. The prediction includes the sunspot number, a measure of how strong a cycle will be, and the cycle’s expected start and peak. This new solar cycle is forecast to be about the same strength as the solar cycle that just ended — both fairly weak. The new solar cycle is expected to peak in July 2025.
