Every day is Asteroid Day at NASA

It’s International Asteroid Day, and today we’re talking about everything asteroids! Although there are no known threats for the next 100 years, our Planetary Defense experts are constantly finding, tracking, and monitoring near-Earth objects to protect our home planet.

Asteroids are rocky remnants from the beginning of our solar system, and as of today, 26,110 near-Earth asteroids have been discovered!

So how do we spot these near-Earth objects? Let’s watch and see:

In addition to tracking and monitoring asteroids, we are also launching several missions to study these rocky relics. By studying asteroids, we can better understand the formation of our solar system. Here are some exciting missions you can look forward to:

OSIRIS-REx: Returning a Sample from Asteroid Bennu

Last year, our OSIRIS-REx mission successfully captured a sample of asteroid Bennu, a 4.5-billion-year-old asteroid the size of the empire state building.

Currently, OSISRIS-REx is making its long journey home carrying this sample as it returns to Earth in 2023.

Psyche: A Journey to a Metal World

Our Psyche mission will journey to a unique metal asteroid orbiting the Sun between Jupiter and Mars.

What makes the asteroid Psyche unique is that it appears to be the exposed nickel-iron core of an early planet, one of the building blocks of our solar system. Deep within rocky, terrestrial planets - including Earth - scientists infer the presence of metallic cores, but these lie unreachably far below the planets' rocky mantles and crusts. Because we cannot see or measure Earth's core directly, Psyche offers a unique window into the violent history of collisions and accretion that created terrestrial planets.

Lucy: Studying the Trojan Asteroids

Launching this year, our Lucy mission will be the first mission to study the Trojans, a group of asteroids that share Jupiter’s orbit around the Sun. Time capsules from the birth of our Solar System more than 4 billion years ago, the swarms of Trojan asteroids associated with Jupiter are thought to be remnants of the primordial material that formed the outer planets.

The mission takes its name from the fossilized human ancestor (called “Lucy” by her discoverers) whose skeleton provided unique insight into humanity's evolution. Likewise, the Lucy mission will revolutionize our knowledge of planetary origins and the formation of the solar system.

DART: Double Asteroid Redirection Test

Launching this year, our DART mission is a planetary defense driven test of technologies and will be the first demonstration of a technique to change the motion of an asteroid in space.

The destination of this mission is the small asteroid Dimorphos, which orbits slowly around its larger companion Didymos. Dimorphos is referred to as a moonlet since it orbits a larger asteroid.

The DART spacecraft will achieve the kinetic impact deflection by deliberately crashing itself into the moonlet. The collision will change the speed of the moonlet in its orbit around the main body by a fraction of one percent, but this will change the orbital period of the moonlet by several minutes - enough to be observed and measured using telescopes on Earth.

At NASA, every day is asteroid day, as we have missions exploring these time capsules of our solar system and surveying the sky daily to find potential hazards. We, along with our partners are watching the skies 24/7/365, so rest assured! We're always looking up.

Getting to Mars: What It’ll Take

Join us as we take a closer look at the next steps in our journey to the Red Planet:

The journey to Mars crosses three thresholds, each with increasing challenges as humans move farther from Earth. We’re managing these challenges by developing and demonstrating capabilities in incremental steps:

Earth Reliant

Earth Reliant exploration is focused on research aboard the International Space Station. From this world-class microgravity laboratory, we are testing technologies and advancing human health and performance research that will enable deep space, long duration missions.

On the space station, we are advancing human health and behavioral research for Mars-class missions. We are pushing the state-of-the-art life support systems, printing 3-D parts and analyzing material handling techniques.

Proving Ground

In the Proving Ground, we will learn to conduct complex operations in a deep space environment that allows crews to return to Earth in a matter of days. Primarily operating in cislunar space (the volume of space around the moon). We will advance and validate the capabilities required for humans to live and work at distances much farther away from our home planet…such as at Mars.

Earth Independent

Earth Independent activities build on what we learn on the space station and in deep space to enable human missions to the Mars vicinity, possibly to low-Mars orbit or one of the Martian moons, and eventually the Martian surface. Future Mars missions will represent a collaborative effort between us and our partners.

Did you know….that through our robotic missions, we have already been on and around Mars for 40 years! Taking nearly every opportunity to send orbiters, landers and rovers with increasingly complex experiments and sensing systems. These orbiters and rovers have returned vital data about the Martian environment, helping us understand what challenges we may face and resources we may encounter.

Through the Asteroid Redirect Mission (ARM), we will demonstrate an advanced solar electric propulsion capability that will be a critical component of our journey to Mars. ARM will also provide an unprecedented opportunity for us to validate new spacewalk and sample handling techniques as astronauts investigate several tons of an asteroid boulder.

Living and working in space require accepting risks – and the journey to Mars is worth the risks. A new and powerful space transportation system is key to the journey, but we will also need to learn new ways of operating in space.

We Need You!

In the future, Mars will need all kinds of explorers, farmers, surveyors, teachers…but most of all YOU! As we overcome the challenges associated with traveling to deep space, we will still need the next generation of explorers to join us on this journey. Come with us on the journey to Mars as we explore with robots and send humans there one day.

Join us as we go behind-the-scenes:

We’re offering a behind-the-scenes look Thursday, Aug. 18 at our journey to Mars. Join us for the following events:

Journey to Mars Televised Event at 9:30 a.m. EDT Join in as we host a conversation about the numerous efforts enabling exploration of the Red Planet. Use #askNASA to ask your questions! Tune in HERE.

Facebook Live at 1:30 p.m. EDT Join in as we showcase the work and exhibits at our Michoud Assembly Facility. Participate HERE.

Roman's primary structure hangs from cables as it moves into the big clean room at NASA's Goddard Space Flight Center.

What Makes the Clean Room So Clean?

When you picture NASA’s most important creations, you probably think of a satellite, telescope, or maybe a rover. But what about the room they’re made in? Believe it or not, the room itself where these instruments are put together—a clean room—is pretty special. 

A clean room is a space that protects technology from contamination. This is especially important when sending very sensitive items into space that even small particles could interfere with.

There are two main categories of contamination that we have to keep away from our instruments. The first is particulate contamination, like dust. The second is molecular contamination, which is more like oil or grease. Both types affect a telescope’s image quality, as well as the time it takes to capture imagery. Having too many particles on our instruments is like looking through a dirty window. A clean room makes for clean science!

Two technicians clean the floor of Goddard’s big clean room.

Our Goddard Space Flight Center in Greenbelt, Maryland has the largest clean room of its kind in the world. It’s as tall as an eight-story building and as wide as two basketball courts.

Goddard’s clean room has fewer than 3,000 micron-size particles per cubic meter of air. If you lined up all those tiny particles, they’d be no longer than a sesame seed. If those particles were the size of 16-inch (0.4-meter) inflatable beach balls, we’d find only 3,000 spread throughout the whole body of Mount Everest!

A clean room technician observes a sample under a microscope.

The clean room keeps out particles larger than five microns across, just seven percent of the width of an average human hair. It does this via special filters that remove around 99.97% of particles 0.3 microns and larger from incoming air. Six fans the size of school buses spin to keep air flowing and pressurize the room. Since the pressure inside is higher, the clean air keeps unclean air out when doors open.

A technician analyzes a sample under ultraviolet light.

In addition, anyone who enters must wear a “bunny suit” to keep their body particles away from the machinery. A bunny suit covers most of the person inside. Sometimes scientists have trouble recognizing each other while in the suits, but they do get to know each other’s mannerisms very well.

This illustration depicts the anatomy of a bunny suit, which covers clean room technicians from head to toe to protect sensitive technology.

The bunny suit is only the beginning: before putting it on, team members undergo a preparation routine involving a hairnet and an air shower. Fun fact – you’re not allowed to wear products like perfume, lotion, or deodorant. Even odors can transfer easily!

Six of Goddard’s clean room technicians (left to right: Daniel DaCosta, Jill Bender, Anne Martino, Leon Bailey, Frank D’Annunzio, and Josh Thomas).

It takes a lot of specialists to run Goddard’s clean room. There are 10 people on the Contamination Control Technician Team, 30 people on the Clean Room Engineering Team to cover all Goddard missions, and another 10 people on the Facilities Team to monitor the clean room itself. They check on its temperature, humidity, and particle counts.

A technician rinses critical hardware with isopropyl alcohol and separates the particulate and isopropyl alcohol to leave the particles on a membrane for microscopic analysis.

Besides the standard mopping and vacuuming, the team uses tools such as isopropyl alcohol, acetone, wipes, swabs, white light, and ultraviolet light. Plus, they have a particle monitor that uses a laser to measure air particle count and size.

The team keeping the clean room spotless plays an integral role in the success of NASA’s missions. So, the next time you have to clean your bedroom, consider yourself lucky that the stakes aren’t so high!

13 Reasons to Have an Out of This World Friday (the 13th)

1. Know that not all of humanity is bound to the ground

Since 2000, the International Space Station has been continuously occupied by humans. There, crew members live and work while conducting important research that benefits life on Earth and will even help us eventually travel to deep space destinations, like Mars.

2. Smart people are up all night working in control rooms all over NASA to ensure that data keeps flowing from our satellites and spacecraft

Our satellites and spacecraft help scientists study Earth and space. Missions looking toward Earth provide information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide, and the amount of energy that Earth absorbs and emits. And satellites monitor wildfires, volcanoes and their smoke.

Satellites and spacecraft that face toward space have a variety of jobs. Some watch for dangerous rays coming from the sun. Others explore asteroids and comets, the history of stars, and the origin of planets. Some fly near or orbit other planets. These spacecraft may look for evidence of water on Mars or capture close-up pictures of Saturn’s rings.

3. The spacecraft, rockets and systems developed to send astronauts to low-Earth orbit as part of our Commercial Crew Program is also helping us get to Mars

Changes to the human body during long-duration spaceflight are significant challenges to solve ahead of a mission to Mars and back. The space station allows us to perform long duration missions without leaving Earth’s orbit. 

Although they are orbiting Earth, space station astronauts spend months at a time in near-zero gravity, which allows scientists to study several physiological changes and test potential solutions. The more time they spend in space, the more helpful the station crew members can be to those on Earth assembling the plans to go to Mars.

4. Two new science missions will travel where no spacecraft has gone before…a Jupiter Trojan asteroid and a giant metal asteroid!

We’ve selected two missions that have the potential to open new windows on one of the earliest eras in the history of our solar system – a time less than 10 million years after the birth of our sun!

The first mission, Lucy, will visit six of Jupiter’s mysterious Trojan asteroids. The Trojans are thought to be relics of a much earlier era in the history of the solar system, and may have formed far beyond Jupiter’s current orbit.

The second mission, Psyche, will study a unique metal asteroid that’s never been visited before. This giant metal asteroid, known as 16 Psyche, is about three times farther away from the sun than is the Earth. Scientists wonder whether Psyche could be an exposed core of an early planet that could have been as large as Mars, but which lost its rocky outer layers due to a number of violent collisions billions of years ago.

5. Even astronauts eat their VEGGIES’s

NASA astronaut Shane Kimbrough collected the third and final harvest of the latest round of the Veggie investigation, testing the capability to grow fresh vegetables on the International Space Station. 

Understanding how plants respond to microgravity is an important step for future long-duration space missions, which will require crew members to grow their own food. Crew members have previously grown lettuce and flowers in the Veggie facility. This new series of the study expands on previous validation tests.

6. When you feel far away from home, you can think of the New Horizons spacecraft as it heads toward the Kuiper Belt, and the twin Voyager spacecraft are beyond the influence of our sun…billions of miles away 

Our New Horizons spacecraft completed its Pluto flyby in July 2015 and has continued on its way toward the Kuiper Belt. The spacecraft continues to send back important data as it travels toward deeper space at more than 32,000 miles per hour, and is nearly 3.2 billion miles from Earth.

In addition to New Horizons, our twin Voyager 1 and 2 spacecraft are exploring where nothing from Earth has flown before. Continuing on their more-than-37-year journey since their 1977 launches, they are each much farther away from Earth and the sun than Pluto. In August 2012, Voyager 1 made the historic entry into interstellar space, the region between the stars, filled with material ejected by the death of nearby stars millions of years ago.

7. Earth has a magnetic field that largely protects it from the solar wind stripping away out atmosphere…unlike Mars

Findings from our MAVEN mission have identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet environment to the cold, arid planet Mars is today. MAVEN data have enabled researchers to determine the rate at which the Martian atmosphere currently is losing gas to space via stripping by the solar wind. Luckily, Earth has a magnetic field that largely protects it from this process. 

8. There are humans brave enough to not only travel in space, but venture outside the space station to perform important repairs and updates during spacewalks

Spacewalks are important events where crew members repair, maintain and upgrade parts of the International Space Station. These activities can also be referred to as EVAs – Extravehicular Activities. Not only do spacewalks require an enormous amount of work to prepare for, but they are physically demanding on the astronauts. They are working in the vacuum of space in only their spacewalking suit. 

When on a spacewalk, astronauts use safety tethers to stay close to their spacecraft. One end of the tether is hooked to the spacewalker, while the other end is connected to the vehicle. Spacewalks typically last around 6.5 hours, but can be extended to 7 or 8 hours, if necessary.

9. We’re working to create new aircraft that will dramatically reduce fuel use, emissions and noise…meaning we could change the way you fly! 

The nation’s airlines could realize more than $250 billion dollars in savings in the near future thanks to green-related technologies that we are developing and refining. These new technologies could cut airline fuel use in half, pollution by 75% and noise to nearly one-eighth of today’s levels!

10. You can see a global image of your home planet…EVERY DAY

Once a day, we will post at least a dozen new color images of Earth acquired from 12 to 36 hours earlier. These images are taken by our EPIC camera from one million miles away on the Deep Space Climate Observatory (DSCOVR). Take a look HERE.

11. Employees of NASA have always been a mission driven bunch, who try to find answers that were previously unknown

The film “Hidden Figures,” focuses on the stories of Katherine Johnson, Mary Jackson and Dorothy Vaughan, African-American women who were essential to the success of early spaceflight. 

Today, we embrace their legacy and strive to include everyone who wants to participate in our ongoing exploration. In the 1960’s, we were on an ambitious journey to the moon, and the human computers portrayed in Hidden Figures helped get us there. Today, we are on an even more ambitious journey to Mars. We are building a vibrant, innovative workforce that reflects a vast diversity of discipline and thought, embracing and nurturing all the talent we have available, regardless of gender, race or other protected status. Take a look at our Modern Figures HERE.

12. A lot of NASA-developed tech has been transferred for use to the public 

Our Technology Transfer Program highlights technologies that were originally designed for our mission needs, but have since been introduced to the public market. HERE are a few spinoff technologies that you might not know about.

13. If all else fails, here’s an image of what we (Earth) and the moon look like from Mars  

From the most powerful telescope orbiting Mars comes a new view of Earth and its moon, showing continent-size detail on the planet and the relative size of the moon. The image combines two separate exposures taken on Nov. 20 by our High Resolution Imaging Science Experiment (HiRISE) camera on our Mars Reconnaissance Orbiter.

In the image, the reddish feature near the middle of the face of Earth is Australia.

NASA’s View of COVID-19

#COVID19 led to changes in human activities around the globe. We can see some of these changes from space. Some bodies of water have run clearer, emissions of pollutants have temporarily declined, and transportation and shipment of goods have decreased.

Along with our partner agencies – ESA and JAXA – we’re making satellite data available on the COVID-19 Earth Observation Dashboard, where you can explore some of the changes we can see from space.

But it’s not just what we can see. When the pandemic began, NASA engineers sprang into action to build ventilators, oxygen hoods and more to help save lives.
