Does Space Have A Standard Time Or Do You Rely On The Time Zones On Earth While You Are In Space?

Astronomy Night at the White House

NASA took over the White House Instagram today in honor of Astronomy Night to share some incredible views of the universe and the world around us. Check out more updates from the astronauts, scientists, and students on South Lawn.

Here’s a nighttime view of Washington, D.C. from the astronauts on the International Space Station on October 17. Can you spot the White House? 

Check out this look at our sun taken by NASA’s Solar Dynamics Observatory. The SDO watches the sun constantly, and it captured this image of the sun emitting a mid-level solar flare on June 25. Solar flares are powerful bursts of radiation. Harmful radiation from a flare can’t pass through Earth’s atmosphere to physically affect humans on the ground. But when they’re intense enough, they can disturb the atmosphere in the layer where GPS and communications signals travel.

Next up is this incredible view of Saturn’s rings, seen in ultraviolet by NASA’s Cassini spacecraft. Hinting at the origin of the rings and their evolution, this ultraviolet view indicates that there’s more ice toward the outer part of the rings than in the inner part.

Take a look at the millions of galaxies that populate the patch of sky known as the COSMOS field, short for Cosmic Evolution Survey. A portion of the COSMOS field is seen here by NASA’s Spitzer Space Telescope. Even the smallest dots in this image are galaxies, some up to 12 billion light-years away. The picture is a combination of infrared data from Spitzer (red) and visible-light data (blue and green) from Japan’s Subaru telescope atop Mauna Kea in Hawaii. The brightest objects in the field are more than ten thousand times fainter than what you can see with the naked eye.

This incredible look at the Cat’s Eye nebula was taken from a composite of data from NASA’s Chandra X-ray Observatory and Hubble Space Telescope. This famous object is a so-called planetary nebula that represents a phase of stellar evolution that the Sun should experience several billion years from now. When a star like the Sun begins to run out of fuel, it becomes what is known as a red giant. In this phase, a star sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures seen with optical telescopes.

This view of the International Space Station is a composite of nine frames that captured the ISS transiting the moon at roughly five miles per second on August 2. The International Space Station is a unique place—a convergence of science, technology, and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. As the third brightest object in the sky, the International Space Station is easy to see if you know when to look up. You can sign up for alerts and get information on when the International Space Station flies over you at spotthestation.nasa.gov. Thanks for following along today as NASA shared the view from astronomy night at the White House. Remember to look up and stay curious!

What’s Up for September?

Stargazing and looking up into the night sky is always a fun thing to do. This month, it will be especially exciting because there will be a total eclipse of a supermoon, plus the opportunity to see planets and the late-summer Milky Way!

What is a supermoon?

A supermoon is a new or full moon that occurs when it is at, or near its closest approach to Earth in a given orbit. There are usually 4 to 6 supermoons every year.

Observers can view the total eclipse on September 27, starting at 10:11 p.m. EDT until 11:23 p.m. This event will be visible in North and South America, as well as Europe and Africa. So make sure to mark your calendars!

This month, you will also be able to see the planets! Look for Mercury, Saturn, Pluto and Neptune in the evening sky. Uranus and Neptune at midnight, and Venus, Mars and Jupiter in the pre-dawn sky.

Finally, if you’re able to escape to a dark location, you might be able to see a great view of our Milky Way!

So, make sure to get outside this month and take a look at everything our night sky has to offer.

What Cargo is Launching in October to the International Space Station?

On Monday, Oct. 17, Orbital ATK is scheduled to send new science experiments to the International Space Station. 

The Cygnus spacecraft will blast off from our Wallops Flight Facility in Virginia at 7:40 p.m. EDT carrying more than 5,100 pounds of science, supplies and equipment.

Let’s take a look at a few of these experiments:

Cool Flames

Low-temperature fires with no visible flames are known as cool flames. The Cool flames experiment examines these low-temperature combustion of droplets of a variety of fuels and additives in low gravity.

Why are we studying this? Data from this experiment could help scientists develop more efficient advanced engines and new fuels for use in space and on Earth.

Lighting Effects

Light plays a powerful role in our daily, or circadian, rhythms. Astronauts aboard the space station experience multiple cycles of light and dark every 24 hours, which, along with night shifts and the stresses of spaceflight, can affect their sleep quantity and quality.

The Lighting Effects investigation tests a new lighting system aboard the station designed to enhance crew health and keep their body clocks in proper sync with a more regular working and resting schedule.

Why are we studying this? Lighting manipulation has potential as a safe, non-pharmacological way to optimize sleep and circadian regulation on space missions. People on Earth, especially those who work night shifts, could also improve alertness and sleep by adjusting lighting for intensity and wavelength.

EveryWear

A user-friendly tablet app provides astronauts with a new and faster way to collect a wide variety of personal data. The EveryWear experiment tests use of this French-designed technology to record and transmit data on nutrition, sleep, exercise and medications. Astronauts use the app to complete questionnaires and keep medical and clinical logs. They wear a Smartshirt during exercise that records heart activity and body positions and transmits these data to the app. Finally, rather than manually recording everything that they eat, crew members scan barcodes on food packets to collect real-time nutritional data.

Why are we studying this? EveryWear has the potential for use in science experiments, biomedical support and technology demonstrations.

Fast Neturon Spectrometer

Outside the Earth’s magnetic field, astronauts are exposed to space radiation that can reduce immune response, increase cancer risk and interfere with electronics.

The Fast Neutron Spectrometer (FNS) experiment will help scientists understand high-energy neutrons, part of the radiation exposure experienced by crews during spaceflight, by studying a new technique to measure electrically neutral neutron particles.

Why are we studying this? This improved measurement will help protect crews on future exploration missions, like our journey to Mars.

A Hitchhiker’s Ride to Space

This month, we are set to launch the latest weather satellite from the National Oceanic and Atmospheric Administration (NOAA). The Joint Polar Satellite System-1, or JPSS-1, satellite will provide essential data for timely and accurate weather forecasts and for tracking environmental events such as forest fires and droughts.

Solar System: Things to Know this Week

On May 22 Mars will be at opposition. That's when Mars, Earth and the sun all line up, with Earth directly in the middle. A few days later, Mars and Earth will reach the points in their orbits around the sun where they are nearest to each other. The closer Mars comes to Earth in its orbit, the larger and brighter it appears in the sky.

It's an opportunity for backyard skywatchers—and a good time to catch up on all the exploration now underway at the Red Planet. Here are a few things to know this week about Mars:

1. Red Star Rising

The best time to see Mars at its brightest is when it's highest in the sky, which is around midnight during May. Look toward the south in the constellation Scorpius (where right now you can also catch the planet Saturn). If you have a telescope, you may be able to pick out some of the features on its surface. But don't fall for Internet rumors claiming that Mars will appear as big as the full moon. Instead, it will look like a bright, reddish or orange star. Get Mars viewing tips HERE.

2. Roving Weather Reporter

Our Mars Curiosity mission has now been roving across the floor of Gale Crater for two full Martian years—that's four Earth years. This robotic geologist is a meteorologist, too, and its long journey has allowed it to observe the local weather for two full seasonal cycles. During that time, the rover's instruments have recorded temperatures ranging from 60.5 degrees Fahrenheit (15.9 degrees Celsius) on a summer afternoon, to minus 148 F (minus 100 C) on a winter night. They also detected an intriguing spike in methane gas—but it hasn't happened since.

3. Increasing Clouds, with a Chance of Dust Storms

The Mars Reconnaissance Orbiter keeps an eye on Martian weather, too, but on a global scale. Every week, you can see the latest weather report, including an animation showing storms and clouds across the face of Mars.

4. Walking the Ancient Shoreline

Mars explorers have studied evidence for years that the early history of the planet included times where liquid water flowed and pooled freely. But just how deep those ancient lakes were, and how long they lasted, remains a topic of debate. A new study offers a more detailed picture of the rise and fall of standing bodies of water.

5. Wish Upon a Star

It's true that Mars will be especially bright in the sky this week. But did you ever consider that Earth often shines for Mars as well? This image from the Curiosity rover shows our whole world as a single point of light. When people finally do stand on Mars, they'll be able to look at the twilight sky—and see home. Left: the Earth and the Moon in the evening sky of Mars, as seen by the Curiosity rover.

What's That Space Rock?

The path through the solar system is a rocky road. Asteroids, comets, Kuiper Belt Objects—all kinds of small bodies of rock, metal and ice are in constant motion as they orbit the Sun. But what’s the difference between them, anyway? And why do these miniature worlds fascinate space explorers so much? The answer is profound: they may hold the keys to better understanding where we all come from. Here’s 10 things to know about the solar system this week:

This picture of Eros, the first of an asteroid taken from an orbiting spacecraft, came from our NEAR mission in February 2000. Image credit: NASA/JPL

1. Asteroids

Asteroids are rocky, airless worlds that orbit our Sun. They are remnants left over from the formation of our solar system, ranging in size from the length of a car to about as wide as a large city. Asteroids are diverse in composition; some are metallic while others are rich in carbon, giving them a coal-black color. They can be “rubble piles,” loosely held together by their own gravity, or they can be solid rocks.

Most of the asteroids in our solar system reside in a region called the main asteroid belt. This vast, doughnut-shaped ring between the orbits of Mars and Jupiter contains hundreds of thousands of asteroids, maybe millions. But despite what you see in the movies, there is still a great deal of space between each asteroid. With all due respect to C3PO, the odds of flying through the asteroid belt without colliding with one are actually pretty good.

Other asteroids (and comets) follow different orbits, including some that enter Earth’s neighborhood. These are called near-Earth objects, or NEOs. We can actually keep track of the ones we have discovered and predict where they are headed. The Minor Planet Center (MPC) and Jet Propulsion Laboratory’s Center for Near Earth Object Studies (CNEOS) do that very thing. Telescopes around the world and in space are used to spot new asteroids and comets, and the MPC and CNEOS, along with international colleagues, calculate where those asteroids and comets are going and determine whether they might pose any impact threat to Earth.

For scientists, asteroids play the role of time capsules from the early solar system, having been preserved in the vacuum of space for billions of years. What’s more, the main asteroid belt may have been a source of water—and organic compounds critical to life—for the inner planets like Earth.

2. Comets

Comets also orbit the Sun, but they are more like snowballs than space rocks. Each comet has a center called a nucleus that contains icy chunks of frozen gases, along with bits of rock and dust. When a comet’s orbit brings it close to the Sun, the comet heats up and spews dust and gases, forming a giant, glowing ball called a coma around its nucleus, along with two tails – one made of dust and the other of excited gas (ions). Driven by a constant flow of particles from the Sun called the solar wind, the tails point away from the Sun, sometimes stretching for millions of miles.

While there are likely billions of comets in the solar system, the current confirmed number is 3,535. Like asteroids, comets are leftover material from the formation of our solar system around 4.6 billion years ago, and they preserve secrets from the earliest days of the Sun’s family. Some of Earth’s water and other chemical constituents could have been delivered by comet impacts.

3. Meteoroids

Meteoroids are fragments and debris in space resulting from collisions among asteroids, comets, moons and planets. They are among the smallest “space rocks.” However, we can actually see them when they streak through our atmosphere in the form of meteors and meteor showers.

This photograph, taken by an astronaut aboard the International Space Station, provides the unusual perspective of looking down on a meteor as it passes through the atmosphere. The image was taken on Aug. 13, 2011, during the Perseid meteor shower that occurs every August. Image credit: NASA

4. Meteors

Meteors are meteoroids that fall through Earth’s atmosphere at extremely high speeds. The pressure and heat they generate as they push through the air causes them to glow and create a streak of light in the sky. Most burn up completely before touching the ground. We often refer to them as “shooting stars.” Meteors may be made mostly of rock, metal or a combination of the two.

Scientists estimate that about 48.5 tons (44,000 kilograms) of meteoritic material falls on Earth each day.

5. Meteor Showers

Several meteors per hour can usually be seen on any given night. Sometimes the number increases dramatically—these events are termed meteor showers. They occur when Earth passes through trails of particles left by comets. When the particles enter Earth’s atmosphere, they burn up, creating hundreds or even thousands of bright streaks in the sky. We can easily plan when to watch meteor showers because numerous showers happen annually as Earth’s orbit takes it through the same patches of comet debris. This year’s Orionid meteor shower peaks on Oct. 21.

6. Meteorites

Meteorites are asteroid, comet, moon and planet fragments (meteoroids) that survive the heated journey through Earth’s atmosphere all the way to the ground. Most meteorites found on Earth are pebble to fist size, but some are larger than a building.

Early Earth experienced many large meteorite impacts that caused extensive destruction. Well-documented stories of modern meteorite-caused injury or death are rare. In the first known case of an extraterrestrial object to have injured a human being in the U.S., Ann Hodges of Sylacauga, Alabama, was severely bruised by a 8-pound (3.6-kilogram) stony meteorite that crashed through her roof in November 1954.

The largest object in the asteroid belt is actually a dwarf planet, Ceres. This view comes from our Dawn mission. The color is approximately as it would appear to the eye. Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

7. Dwarf Planets

Don’t let the name fool you; despite their small size, dwarf planets are worlds that are just as compelling as their larger siblings. Dwarf planets are defined by astronomers as bodies massive enough to be shaped by gravity into a round or nearly round shape, but they don’t have enough of their own gravitational muscle to clear their path of other objects as they orbit the Sun. In our solar system, dwarf planets are mostly found in the Kuiper Belt beyond Neptune; Pluto is the best-known example. But the largest object in the asteroid belt is the dwarf planet Ceres. Like Pluto, Ceres shows signs of active geology, including ice volcanoes.

8. Kuiper Belt Objects

The Kuiper Belt is a disc-shaped region beyond Neptune that extends from about 30 to 55 astronomical units -- that is, 30 to 55 times the distance from the Earth to the Sun. There may be hundreds of thousands of icy bodies and a trillion or more comets in this distant region of our solar system.

Besides Pluto, some of the mysterious worlds of the Kuiper Belt include Eris, Sedna, Quaoar, Makemake and Haumea. Like asteroids and comets, Kuiper Belt objects are time capsules, perhaps kept even more pristine in their icy realm.

This chart puts solar system distances in perspective. The scale bar is in astronomical units (AU), with each set distance beyond 1 AU representing 10 times the previous distance. One AU is the distance from the Sun to the Earth, which is about 93 million miles or 150 million kilometers. Neptune, the most distant planet from the Sun, is about 30 AU. Image credit: NASA/JPL-Caltech

9. Oort Cloud Objects

The Oort Cloud is a group of icy bodies beginning roughly 186 billion miles (300 billion kilometers) away from the Sun. While the planets of our solar system orbit in a flat plane, the Oort Cloud is believed to be a giant spherical shell surrounding the Sun, planets and Kuiper Belt Objects. It is like a big, thick bubble around our solar system. The Oort Cloud’s icy bodies can be as large as mountains, and sometimes larger.

This dark, cold expanse is by far the solar system’s largest and most distant region. It extends all the way to about 100,000 AU (100,000 times the distance between Earth and the Sun) – a good portion of the way to the next star system. Comets from the Oort Cloud can have orbital periods of thousands or even millions of years. Consider this: At its current speed of about a million miles a day, our Voyager 1 spacecraft won’t reach the Oort Cloud for more than 300 years. It will then take about 30,000 years for the spacecraft to traverse the Oort Cloud, and exit our solar system entirely.

10. The Explorers

Fortunately, even though the Oort Cloud is extremely distant, most of the small bodies we’ve been discussing are more within reach. In fact, NASA and other space agencies have a whole flotilla of robotic spacecraft that are exploring these small worlds up close. Our mechanical emissaries act as our eyes and hands in deep space, searching for whatever clues these time capsules hold.

A partial roster of our current or recent missions to small, rocky destinations includes:

OSIRIS-REx – Now approaching the asteroid Bennu, where it will retrieve a sample in 2020 and return it to the Earth for close scrutiny.

New Horizons – Set to fly close to MU69 or “Ultima Thule,” an object a billion miles past Pluto in the Kuiper Belt on Jan. 1, 2019. When it does, MU69 will become the most distant object humans have ever seen up close.

Psyche – Planned for launch in 2022, the spacecraft will explore a metallic asteroid of the same name, which may be the ejected core of a baby planet that was destroyed long ago.

Lucy – Slated to investigate two separate groups of asteroids, called Trojans, that share the orbit of Jupiter – one group orbits ahead of the planet, while the other orbits behind. Lucy is planned to launch in 2021.

Dawn – Finishing up a successful seven-year mission orbiting planet-like worlds Ceres and Vesta in the asteroid belt.

Plus these missions from other space agencies:

The Japan Aerospace Exploration Agency (JAXA)’s Hayabusa2– Just landed a series of small probes on the surface of the asteroid Ryugu.

The European Space Agency (ESA)’s Rosetta – Orbited the comet 67P/Churyumov-Gerasimenko and dispatched a lander to its surface.

One Hot Year after Another

Globally, 2020 was the hottest year on record, effectively tying 2016, the previous record. Overall, Earth’s average temperature has risen more than 2 degrees Fahrenheit since the 1880s.

Temperatures are increasing due to human activities, specifically emissions of greenhouse gases, like carbon dioxide and methane. 

Heat and the energy it carries are what drive our planet: winds, weather, droughts, floods, and more are expressions of heat. The right amount of heat is even one of the things that makes life on Earth possible. But too much heat is changing the way our planet’s systems act.

My World’s on Fire

Higher temperatures drive longer, more intense fire seasons. As rain and snowfall patterns change, some regions are getting drier and more vulnerable to damage, setting the stage for more fires.

2020 saw several record-breaking fires, both in Australia in the beginning of the year, and in the western U.S. through northern summer and fall. Smoke from fires in both regions reached so high into the atmosphere that it formed clouds and continues to travel around the globe today.

In the Siberian Arctic, unusually high temperatures helped drive at least 19 fires in the region. More than half of them were burning peat soil -- decomposed organic materials -- that stores a lot of carbon. Peat fires release vast amounts of carbon into the atmosphere, potentially leading to even more warming.

The Water’s Getting Warm

It wasn’t just fire seasons setting records. 2020 had more named tropical storms in the Atlantic and more storms making landfall in the U.S. than any hurricane season on record.

Hurricanes rely on warm ocean water as fuel, and this year, the Atlantic provided. 30 named storms weren’t the only things that made this year’s hurricane season notable.

Storms like Eta, Delta, and Iota quickly changed from smaller, weaker tropical storms into more destructive hurricanes. This rapid intensification is complicated, but it’s likely that warmer, more humid weather -- a result of climate change -- helps drive it.

The Ice Is Getting Thin

Add enough heat, and even the biggest chunk of ice will melt. That’s true whether we’re talking about the ice cubes in your glass or the vast sheets of ice at our planet’s poles. Right now, the Arctic region is warming about three times faster than the rest of our planet, which has some major effects both locally and globally.

This year, Arctic sea ice hit a near-record low. Sea ice is actually made of frozen ocean water, and it grows and thaws with the seasons, typically reaching an annual minimum extent in September.

Warmer ocean water led to more ice melting this year, and 2020’s annual minimum extent continued a long trend of shrinking Arctic sea ice extent.

A Long Trend

We study Earth and how it’s changing from the ground, the sky, and space. Using data from sensors all around the planet, we calculate the global average temperature, working with our partners at NOAA.

Many other organizations also track global temperature using their own instruments and methods, and they all match remarkably well. The last seven years were the hottest seven years on record. Earth is getting warmer.

We also study the effects of increasing temperatures, like the melting sea ice and longer fire seasons mentioned above. Additionally, we can study the cause of climate change from space, with a bird’s eye view of increasing carbon in the atmosphere.

The planet is changing because of human activities. We’re working together with other agencies to monitor changes and understand what this means for people in the future.

Exploring Our National Parks…from Space!

The United States has nearly 84 million acres of historic and scenic land in its national parks system. In celebration of National Park Week, here are some satellite views of a few of those national treasures.

Throughout National Park Week, you can #FindYourPark and visit for free.

Yosemite National Park – California

Naked summits alternate with forested lowlands in Yosemite Valley, part of California’s Yosemite National Park. Our Landsat 7 satellite captured this true-color image of part of the Yosemite Valley on Aug. 8, 2001.

Yellowstone National Park – Wyoming, Idaho and Montana

Established in 1872, it was the first national park in the United States, and the world! Its geological and biological wonders have led international groups to declare it a world heritage site and a biosphere reserve. Yellowstone National Park captures the spirit and purpose of the National Park Service, blending modern and ancient human history with nature in its raw complexity.

Hot Springs National Park – Arkansas

National Parks usually make us think of pristine landscapes untouched by human civilization. Most of the 59 national parks in the United States fit that mold, but there are a few exceptions. Arkansas’s Hot Springs National Park, the country’s smallest and most urban, is one of them. Hot Springs, a city of 96,000 people, lies at the southern edge of the park and partly within its boarders.

Shenandoah National Park – Virginia

This long, narrow park in the Blue Ridge Mountains spans more than 179,000 acres, with 40% of the land protected as wilderness. More than 95% of the park is forested, sheltering 1,300 plant species and 267 types of trees and shrubs. The park contains 577 archeological sites, more than 100 cemeteries, and some rocks that date back a billion years.

Olympic National Park – Washington

Possibly one of America’s most diverse national landscapes, Olympic National Park is situated on the Olympic Peninsula in northwestern Washington. If you walked from west to east across the park, you would start at the rocky Pacific shoreline, move into rare temperate rainforests and lush river valleys, ascend glaciers and rugged mountain peaks, and then descend into a comparatively dry rain shadow and alpine forest. From beach to the top of Mount Olympus, you would rise 7,980 feet above sea level.

Colorado National Monument – Colorado

Along the Interstate 70 corridor in western Colorado, well-watered croplands, residential properties and urbanized areas create a broad stripe of green and gray. Away from the interstate, dry climate conditions color the landscape shades of beige, brick and tan. Yet these arid regions offer treasures of their own, including stunning vistas and wildlife both living and extinct. The varied landscapes of this park show the effects of tens of millions of years of erosion.

The images above were produced by our Earth Observatory as part of its 2016 series featuring the National Park Service properties. Check out more HERE.
