Here’s What You Need to Know About Near-Earth Objects

Our solar system is littered with asteroids and comets, and sometimes they get a little close to Earth. But no need to worry! This happens all the time. When an asteroid or comet could come close to our planet, it’s known as a near-Earth object – aka NEO.

But how close is “close”?

A near-Earth object is defined as an object that could pass by our Earth within 30 million miles. We begin to keep close watch on objects that could pass within 5 million miles of our planet.

To put that into perspective, our Moon is only 238,900 miles away.

However unlikely an impact is, we want to know about all near-Earth objects. Our Planetary Defense Coordination Office maintains watch for asteroids and comets coming close to Earth. Along with our partners, we discover, catalog and characterize these bodies.

But what if one of these objects posed a threat?

We want to be prepared. That is why we are working on several deflection techniques and technologies to help protect our planet.

So next time that you hear of an asteroid passing “close” to Earth, know that it’s just one of many that we are tracking.

Here are 10 more things you should know about Planetary Defense.

TESS: The Planet Hunter

So you’re thinking...who’s TESS? But, it’s more like: WHAT is TESS? 

The Transiting Exoplanet Survey Satellite (TESS) is an explorer-class planet finder that is scheduled to launch in April 2018. This mission will search the entire sky for exoplanets — planets outside our solar system that orbit sun-like stars.

In the first-ever space borne all-sky transit survey, TESS will identify planets ranging from Earth-sized to gas giants, orbiting a wide range of stellar types and orbital distances.

The main goal of this mission is to detect small planets with bright host stars in the solar neighborhood, so that we can better understand these planets and their atmospheres.

TESS will have a full time job monitoring the brightness of more than 200,000 stars during a two year mission. It will search for temporary drops in brightness caused by planetary transits. These transits occur when a planet’s orbit carries it directly in front of its parent star as viewed from Earth (cool GIF below).

TESS will provide prime targets for further, more detailed studies with the James Webb Space Telescope (JWST), as well as other large ground-based and space-based telescopes of the future.

What is the difference between TESS and our Kepler spacecraft?

TESS and Kepler address different questions: Kepler answers "how common are Earth-like planets?" while TESS answers “where are the nearest transiting rocky planets?”

What do we hope will come out of the TESS mission?

The main goal is to find rocky exoplanets with solid surfaces at the right distance from their stars for liquid water to be present on the surface. These could be the best candidates for follow-up observations, as they fall within the “habitable zone” and be at the right temperatures for liquid water on their surface.

TESS will use four cameras to study sections of the sky’s north and south hemispheres, looking for exoplanets. The cameras would cover about 90 percent of the sky by the end of the mission. This makes TESS an ideal follow-up to the Kepler mission, which searches for exoplanets in a fixed area of the sky. Because the TESS mission surveys the entire sky, TESS is expected to find exoplanets much closer to Earth, making them easier for further study.

Let Us See Jupiter Through Your Eyes

Our Juno spacecraft will fly over Jupiter’s Great Red Spot on July 10 at 10:06 p.m. EDT. This will be humanity’s first up-close and personal view of the gas giant’s iconic 10,000-mile-wide storm, which has been monitored since 1830 and possibly existing for more than 350 years.

The data collection of the Great Red Spot is part of Juno’s sixth science flyby over Jupiter’s mysterious cloud tops. Perijove (the point at which an orbit comes closest to Jupiter’s center) will be July 10 at 9:55 p.m. EDT. 

At the time of perijove, Juno will be about 2,200 miles above the planet’s cloud tops. Eleven minutes and 33 seconds later…Juno will have covered another 24,713 miles and will be directly above the coiling crimson cloud tops of the Great Red Spot. The spacecraft will pass about 5,600 miles above its clouds. 

When will we see images from this flyby?

During the flyby, all eight of the spacecraft’s instruments will be turned on, as well as its imager, JunoCam. Because the spacecraft will be collecting data with its Microwave Radiometer (MWR), which measures radio waves from Jupiter’s deep atmosphere, we cannot downlink information during the pass. The MWR can tell us how much water there is and how material is moving far below the cloud tops.

During the pass, all data will be stored on-board…with a downlink planned afterwards. Once the downlink begins, engineering data from the spacecraft’s instruments will come to Earth first, followed by images from JunoCam.

The unprocessed, raw images will be located HERE, on approximately July 14. Follow @NASAJuno on Twitter for updates.

Did you know you can download and process these raw images?

We invite the public to act as a virtual imaging team…participating in key steps of the process, from identifying features of interest to sharing the finished images online. After JunoCam data arrives on Earth, members of the public can process the images to create color pictures. The public also helps determine which points on the planet will be photographed. Learn more about voting on JunoCam’s next target HERE.

JunoCam has four filters: red, green, blue and near-infrared. We get red, green and blue strips on one spacecraft rotation (the spacecraft rotation rate is 2 revolutions per minute) and the near-infrared strips on the second rotation. To get the final image product, the strips must be stitched together and the colors lined up.

Anything from cropping to color enhancing to collaging is fair game. Be creative!

Submit your images to Juno_outreach@jpl.nasa.gov to be featured on the Mission Juno website!

The Moon in Motion

Happy New Year! And happy supermoon! Tonight, the Moon will appear extra big and bright to welcome us into 2018 – about 6% bigger and 14% brighter than the average full Moon. And how do we know that? Well, each fall, our science visualizer Ernie Wright uses data from the Lunar Reconnaissance Orbiter (LRO) to render over a quarter of a million images of the Moon. He combines these images into an interactive visualization, Moon Phase and Libration, which depicts the Moon at every day and hour for the coming year. 

Want to see what the Moon will look like on your birthday this year? Just put in the date, and even the hour (in Universal Time) you were born to see your birthday Moon.

Our Moon is quite dynamic. In addition to Moon phases, our Moon appears to get bigger and smaller throughout the year, and it wobbles! Or at least it looks that way to us on Earth. This wobbling is called libration, from the Latin for ‘balance scale’ (libra). Wright relies on LRO maps of the Moon and NASA orbit calculations to create the most accurate depiction of the 6 ways our Moon moves from our perspective.

1. Phases

The Moon phases we see on Earth are caused by the changing positions of the Earth and Moon relative to the Sun. The Sun always illuminates half of the Moon, but we see changing shapes as the Moon revolves around the Earth. Wright uses a software library called SPICE to calculate the position and orientation of the Moon and Earth at every moment of the year. With his visualization, you can input any day and time of the year and see what the Moon will look like!

2. Shape of the Moon

Check out that crater detail! The Moon is not a smooth sphere. It’s covered in mountains and valleys and thanks to LRO, we know the shape of the Moon better than any other celestial body in the universe. To get the most accurate depiction possible of where the sunlight falls on the lunar surface throughout the month, Wright uses the same graphics software used by Hollywood design studios, including Pixar, and a method called ‘raytracing’ to calculate the intricate patterns of light and shadow on the Moon’s surface, and he checks the accuracy of his renders against photographs of the Moon he takes through his own telescope.

3. Apparent Size 

The Moon Phase and Libration visualization shows you the apparent size of the Moon. The Moon’s orbit is elliptical, instead of circular - so sometimes it is closer to the Earth and sometimes it is farther. You’ve probably heard the term “supermoon.” This describes a full Moon at or near perigee (the point when the Moon is closest to the Earth in its orbit). A supermoon can appear up to 14% bigger and brighter than a full Moon at apogee (the point when the Moon is farthest from the Earth in its orbit). 

Our supermoon tonight is a full Moon very close to perigee, and will appear to be about 14% bigger than the July 27 full Moon, the smallest full Moon of 2018, occurring at apogee. Input those dates into the Moon Phase and Libration visualization to see this difference in apparent size!

4. East-West Libration

Over a month, the Moon appears to nod, twist, and roll. The east-west motion, called ‘libration in longitude’, is another effect of the Moon’s elliptical orbital path. As the Moon travels around the Earth, it goes faster or slower, depending on how close it is to the Earth. When the Moon gets close to the Earth, it speeds up thanks to an additional pull from Earth’s gravity. Then it slows down, when it’s farther from the Earth. While this speed in orbital motion changes, the rotational speed of the Moon stays constant. 

This means that when the Moon moves faster around the Earth, the Moon itself doesn’t rotate quite enough to keep the same exact side facing us and we get to see a little more of the eastern side of the Moon. When the Moon moves more slowly around the Earth, its rotation gets a little ahead, and we see a bit more of its western side.

5. North-South Libration

The Moon also appears to nod, as if it were saying “yes,” a motion called ‘libration in latitude’. This is caused by the 5 degree tilt of the Moon’s orbit around the Earth. Sometimes the Moon is above the Earth’s northern hemisphere and sometimes it’s below the Earth’s southern hemisphere, and this lets us occasionally see slightly more of the northern or southern hemispheres of the Moon! 

6. Axis Angle

Finally, the Moon appears to tilt back and forth like a metronome. The tilt of the Moon’s orbit contributes to this, but it’s mostly because of the 23.5 degree tilt of our own observing platform, the Earth. Imagine standing sideways on a ramp. Look left, and the ramp slopes up. Look right and the ramp slopes down. 

Now look in front of you. The horizon will look higher on the right, lower on the left (try this by tilting your head left). But if you turn around, the horizon appears to tilt the opposite way (tilt your head to the right). The tilted platform of the Earth works the same way as we watch the Moon. Every two weeks we have to look in the opposite direction to see the Moon, and the ground beneath our feet is then tilted the opposite way as well.

So put this all together, and you get this:

Beautiful isn’t it? See if you can notice these phenomena when you observe the Moon. And keep coming back all year to check on the Moon’s changing appearance and help plan your observing sessions.

Celebrating Women’s History Month: Most Recent Female Astronauts

For Women’s History Month, NASA and the International Space Station celebrate the women who conduct science aboard the orbiting lab. As of March 2019, 63 women have flown in space, including cosmonauts, astronauts, payload specialists, and space station participants. The first woman in space was Russian cosmonaut Valentina Tereshkova who flew on Vostok 6 on June 16, 1963. The first American woman in space, Sally Ride, flew aboard the Space Shuttle STS-7 in June of 1983.

If conducted as planned, the upcoming March 29 spacewalk with Anne McClain and Christina Koch would be the first all-female spacewalk. Women have participated in science on the space station since 2001; here are the most recent and some highlights from their scientific work:

Christina Koch, Expedition 59

Christina Koch (pictured on the right) becomes the most recent woman in space, launching to the space station in mid-March to take part in some 250 research investigations and technology demonstrations. Koch served as station chief of the American Samoa Observatory and has contributed to the development of instruments used to study radiation particles for the Juno mission and the Van Allen Probe.

Anne McClain, Expedition 57/58, 59

Flight Engineer Anne McClain collects samples for Marrow, a long-term investigation into the negative effects of microgravity on the bone marrow and blood cells it produces. The investigation may lead to development of strategies to help prevent these effects in future space explorers, as well as people on Earth who experience prolonged bed rest. McClain holds the rank of Lieutenant Colonel as an Army Aviator, with more than 2,000 flight hours in 20 different aircraft.

Serena M. Auñón-Chancellor, Expedition 56/57

Serena Auñón-Chancellor conducts research operations for the AngieX Cancer Therapy inside the Microgravity Science Glovebox (MSG). This research may facilitate a cost-effective drug testing method and help develop safer and more effective vascular-targeted treatments. As a NASA Flight Surgeon, Auñón-Chancellor spent more than nine months in Russia supporting medical operations for International Space Station crew members. 

Peggy Whitson, Expeditions 5, 16, 50, 51/52

Astronaut Peggy Whitson holds numerous spaceflight records, including the U.S. record for cumulative time in space – 665 days – and the longest time for a woman in space during a single mission, 289 days. She has tied the record for the most spacewalks for any U.S. astronaut and holds the record for the most spacewalk time for female space travelers. She also served as the first science officer aboard the space station and the first woman to be station commander on two different missions. During her time on Earth, she also is the only woman to serve as chief of the astronaut office. Here she works on the Genes in Space-3 experiment, which completed the first-ever sample-to-sequence process entirely aboard the International Space Station. This innovation makes it possible to identify microbes in real time without having to send samples back to Earth, a revolutionary step for microbiology and space exploration.  

Kate Rubins, Expedition 48/49

The Heart Cells investigation studies the human heart, specifically how heart muscle tissue contracts, grows and changes its gene expression in microgravity and how those changes vary between subjects. In this image, NASA astronaut Kate Rubins conducts experiment operations in the U.S. National Laboratory. Rubins also successfully sequenced DNA in microgravity for the first time as part of the Biomolecule Sequencer experiment.

Samantha Cristoforetti, Expedition 42/43

The first Italian woman in space, European Space Agency (ESA) astronaut Samantha Cristoforetti conducts the SPHERES-Vertigo investigation in the Japanese Experiment Module (JEM). The investigation uses free-flying satellites to demonstrate and test technologies for visual inspection and navigation in a complex environment.

Elena Serova, Expedition 41/42

Cosmonaut Elena Serova, the first Russian woman to visit the space station, works with the bioscience experiment ASEPTIC in the Russian Glavboks (Glovebox). The investigation assessed the reliability and efficiency of methods and equipment for assuring aseptic or sterile conditions for biological investigations performed on the space station. 

Karen Nyberg, Expedition 36/37

NASA astronaut Karen Nyberg sets up the Multi-Purpose Small Payload Rack (MSPR) fluorescence microscope in the space station’s Kibo laboratory. The MSPR has two workspaces and a table used for a wide variety of microgravity science investigations and educational activities.

Sunita Williams, Expeditions 32/33, 14/15

This spacewalk by NASA astronaut Sunita Williams and Japan Aerospace Exploration Agency (JAXA) astronaut Aki Hoshide, reflected in Williams’ helmet visor, lasted six hours and 28 minutes. They completed installation of a main bus switching unit (MBSU) and installed a camera on the International Space Station’s robotic Canadarm2. Williams participated in seven spacewalks and was the second woman ever to be commander of the space station. She also is the only person ever to have run a marathon while in space. She flew in both the space shuttle and Soyuz, and her next assignment is to fly a new spacecraft: the Boeing CST-100 Starliner during its first operational mission for NASA’s Commercial Crew Program. 

Cady Coleman, Expeditions 26/27

Working on the Capillary Flow Experiment (CFE), NASA astronaut Catherine (Cady) Coleman performs a Corner Flow 2 (ICF-2) test. CFE observes the flow of fluid in microgravity, in particular capillary or wicking behavior. As a participant in physiological and equipment studies for the Armstrong Aeromedical Laboratory, she set several endurance and tolerance records. Coleman logged more than 4,330 total hours in space aboard the Space Shuttle Columbia and the space station.

Tracy Caldwell Dyson, Expedition 24

A system to purify water for use in intravenous administration of saline would make it possible to better treat ill or injured crew members on future long-duration space missions. The IVGEN investigation demonstrates hardware to provide that capability. Tracy Caldwell Dyson sets up the experiment hardware in the station’s Microgravity Science Glovebox (MSG). As noted above, she and Shannon Walker were part of the first space station crew with more than one woman. 

Shannon Walker, Expedition 24/25

Astronaut Shannon Walker flew on Expedition 24/25, a long-duration mission that lasted 163 days. Here she works at the Cell Biology Experiment Facility (CBEF), an incubator with an artificial gravity generator used in various life science experiments, such as cultivating cells and plants on the space station.  She began working in the space station program in the area of robotics integration, worked on avionics integration and on-orbit integrated problem-solving for the space station in Russia, and served as deputy and then acting manager of the On-Orbit Engineering Office at NASA prior to selection as an astronaut candidate.

Stephanie Wilson, STS-120, STS-121, STS-131

Astronaut Stephanie Wilson unpacks a Microgravity Experiment Research Locker Incubator II (MERLIN) in the Japanese Experiment Module (JEM). Part of the Cold Stowage Fleet of hardware, MERLIN provides a thermally controlled environment for scientific experiments and cold stowage for transporting samples to and from the space station. Currently serving as branch chief for crew mission support in the Astronaut Office, Wilson logged more than 42 days in space on three missions on the space shuttle, part of the Space Transportation System (STS). 

Other notable firsts:

• Roscosmos cosmonaut Svetlana Savitskaya, the first woman to participate in an extra-vehicular activity (EVA), or spacewalk, on July 25, 1984

• NASA astronaut Susan Helms, the first female crew member aboard the space station, a member of Expedition 2 from March to August 2001

• NASA astronaut Peggy Whitson, the first female ISS Commander, April 2008, during a six-month tour of duty on Expedition 16

• The most women in space at one time (four) happened in 2010, when space shuttle Discovery visited the space station for the STS-131 mission. Discovery’s crew of seven included NASA astronauts Dorothy Metcalf-Lindenburger and Stephanie Wilson and Japan Aerospace Exploration Agency (JAXA) astronaut Naoko Yamazaki. The space station crew of six included NASA astronaut Tracy Caldwell Dyson.

• Susan Helms shares the record for longest single spacewalk, totaling 8 hours 56 minutes with fellow NASA astronaut Jim Voss. 

• Expedition 24 marked the first with two women, NASA astronauts Shannon Walker and Tracy Caldwell Dyson, assigned to a space station mission from April to September, 2010

• The 2013 astronaut class is the first with equal numbers of women and men. 

• NASA astronaut Anne McClain became the first woman to live aboard the space station as part of two different crews with other women: Serena Auñón-Chancellor in December 2018 and currently in orbit with Christina Koch.

NASA Technology in Your Life

How does NASA technology benefit life on Earth? It probably has an impact in more ways than you think! Since 1976, our Spinoff program has profiled nearly 2,000 space technologies that have transformed into commercial products and services. In celebration of Spinoff’s 40th year of publication, we’ve assembled a collection of spinoffs that have had the greatest impact on Earth. 

Take a look and see how many you utilize on a regular basis:

Digital Image Sensors

Whether you take pictures and videos with a DSLR camera or a cell phone, or even capture action on the go with a device like a GoPro Hero, you’re using NASA technology. The CMOS active pixel sensor in most digital image- capturing devices was invented when we needed to miniaturize cameras for interplanetary missions. This technology is also widely used in medical imaging and dental X-ray devices.

Enriched Baby Formula

While developing life support for Mars missions, NASA-funded researchers discovered a natural source for an omega-3 fatty acid previously found primarily in breast milk that plays a key role in infant development. The ingredient has since been added to more than 90% of infant formula on the market and is helping babies worldwide develop healthy brains, eyes and hearts.

NASTRAN Software

NASTRAN is a software developed by our engineers that performs structural analysis in the 1960s. Still popular today, it’s been used to help design everything from airplanes and cars to nuclear reactors and even Disney’s Space Mountain roller coaster.

Food Safety Standards

Looking to ensure the absolute safety of prepackaged foods for spaceflight, we partnered with the Pillsbury Company to create a new, systematic approach to quality control. Now known as Hazard Analysis and Critical Control Points (HACCP), the method has become an industry standard that benefits consumers worldwide by keeping food free from a wide range of potential chemical, physical and biological hazards.

Neutral Body Posture Specifications

What form does the human body naturally assume when all physical influences, including the pull of gravity, stop affecting it? We conducted research to find out using Skylab, America’s first space station, and later published specifications for what it called neutral body posture. The study has informed seat designs in everything from airplanes and office chairs to several models of Nissan automobiles.

Advanced Water Filtration

We recently discovered unexpected sources of water on the moon and Mars, but even so, space remains a desert for human explorers, and every drop must be recycled and reused. A nano filter devised to purify water in orbit is currently at work on Earth, in devices that supply water to remote villages as well as in a water bottle that lets hikers and adventurers stay hydrated using streams and lakes.

Swimsuit Designs

Wind-tunnel testing at our Langley Research Center played a key role in the development of Speedo’s LZR Racer swimsuit, proving which materials and seams best reduced drag as a swimmer cuts through the water. The swimsuit made a splash during its Olympic debut in 2008, as nearly every medal winner and world-record breaker wore the suit.

Air Purifier

When plants grow, they release a gas called ethylene that accelerates decay, hastening the wilting of flowers and the ripening of fruits and vegetables. Air circulation on Earth keeps the fumes from building up, but in the hermetically sealed environment of a spacecraft, ethylene poses a real challenge to the would-be space farmers. We funded the development of an ethylene scrubber for the International Space Station that has subsequently proved capable of purifying air on Earth from all kinds of pathogens and particulates. Grocery stores use it to keep produce fresh longer. It’s also been marketed for home use and has even been embraced by winemakers, who employ the scrubber to keep aging wine in barrels free from mold, mildew and musty odors.

Scratch-Resistant, UV-Reflective Lenses

Some of the earliest research into effective scratch-resistant coatings for prescription and sunglass lenses drew from work done at Ames Research Center on coatings for astronaut helmet visors and plastic membranes used in water purification systems. In the 1980s, we developed sunlight-filtering lenses to provide eye protection and enhance colors, and these lenses have found their way into sunglasses, ski goggles and safety masks for welders.

Dustbuster

An Apollo-era partnership with Black & Decker to build battery-operated tools for moon exploration and sample collection led to the development of a line of consumer, medical and industrial hand-held cordless tools. This includes the popular Dustbuster cordless vacuum.
