The International Space Station Through the Eyes of Little Earth!

Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph. Accompanying their mission is a zero-g indicator, informally known as “Little Earth”. 

Greetings fellow Earthlings! Curious about my first week on the International Space Station? What does a normal day look like when you’re living and working hundreds of miles above Earth? Take a look at some photos from my first week, when I was still learning the ropes from my new roommates!

Welcome Ceremony

Talk about a warm welcome! I arrived on March 3, 2019 when the SpaceX Crew Dragon docked to the Space Station for the first time. This historic mission marked the first time a commercially built American spacecraft intended for human spaceflight docked to the orbital lab. Though un-crewed, Dragon was carrying two very important passengers – my space travel companion Ripley and myself, Astronaut Little Earth. During my three-day introduction to the station, two Expedition 59 astronauts, Anne McClain and David Saint-Jacques, taught me what it takes to be a Space Station crew member!

Earth Watching

First thing’s first – the VIEW. After the traditional hatch opening welcome ceremony, I was off to the Cupola Observational Module. Designed for the observation of operations outside the station, this module’s six side windows also provide spectacular views of our Mother Earth! My roommate Anne McClain introduced me to the beautiful vantage point of space. Clearly, I was a little star-struck.

Space Suit Sizing

Next, it was time to get to work – lending a hand with Anne McClain’s space suit sizing. Did you know you actually grow in zero gravity? Astronaut McClain has grown two inches on her current mission in space. Crew members must account for this change in growth to know if different components need to be switched out of their individual spacesuit for a better fit. When pressurized and filled with oxygen, the spacesuits become stiff objects around the astronauts inside, making it critical they fit comfortably. These spacesuits are essentially mini spacecraft that provide protection and a means of survival for the astronauts as they venture outside the space station and into the harsh environment of space.

Space Coffee!

One Café Latte, please! I was thrilled to find out that even in space, the morning begins with a pick me up. Due to microgravity, liquids tend to get sticky and cling to the wall of cups, making these plastic pouches and straws necessary for consumption. Astronauts in 2015 got an upgrade to their morning cup of joe thanks to SpaceX, Lavazza and the Italian Space Agency. Named the ISSpresso, a microgravity coffee maker has brought authentic Italian espresso with zero-G coffee cups onto the International Space Station.

Emergency Mask Donning

Fueled up and ready for the day, my next agenda item was emergency preparedness practice. There is no 9-1-1 in space, and three events that could pose a dangerous threat to the Space Station include a fire, a depressurization event or an ammonia breakout. Here, Canadian Astronaut David Saint-Jacques and I practiced emergency mask donning in the unlikely event of an ammonia leak into the station’s atmosphere.

Preventative Maintenance

From astronaut to astro-plumber, I traded my mask for goggles with Astronaut Anne McClain during a briefing on plumbing routine maintenance. Because the International Space Station never returns to Earth, the crew is trained to regularly inspect, replace and clean parts inside the station.

Daily Exercise

Talk about staying healthy! After a busy day, Astronaut McClain and I continued to hit the ground running, literally. Crew members are required to work out daily for about two hours to help keep their heart, bones and muscles strong in zero gravity. The harness McClain is wearing is very much like a backpacking harness, designed to evenly distribute weight across her upper body and is attached to a system of bungees and cords. Depending on the tension in these attachments, a specific load of pressure is applied to her body onto the machine.

Strength Training in Zero-G

Watch out, deadlift going on. Running isn’t the only gym exercise they have onboard; strength training is also incorporated into the daily exercise regime.

Robotics Operations: Canadarm2 

You can look, just don’t touch they told me. Whoops. This was a definite highlight, my Canadarm 2 briefing. That black nob by my hand is the translational hand controller. It operates the up and down function of the 57.7-foot-long robotic arm. The Canadarm2 lends a literal helping hand with many station functions, using a “hand” known as a Latching End Effector to perform tasks such as in orbit maintenance, moving supplies and performing “cosmic catches”.

Crew Group Dinner 

Whew, you work up a big appetite working on the Space Station. Ending the day, I was introduced to a crew favorite, group dinner! Astronauts and cosmonauts from around the world come together on the orbital lab and bring with them a variety of cultures and ... food! Though each country is responsible for feeding its own members, when on board the astronauts can share as they please. A new friend of mine, Paxi from the European Space Agency, welcomed my visit and we split a delicious space-shrimp cocktail.

And that’s a wrap to a busy first week aboard the International Space Station! Learn more about what it means to live and work aboard the International Space Station, and click here to see if you have what it takes to become a NASA Astronaut. Until next time!

Eclipse Across America

August 21, 2017, the United States experienced a solar eclipse! 

An eclipse occurs when the Moon temporarily blocks the light from the Sun. Within the narrow, 60- to 70-mile-wide band stretching from Oregon to South Carolina called the path of totality, the Moon completely blocked out the Sun’s face; elsewhere in North America, the Moon covered only a part of the star, leaving a crescent-shaped Sun visible in the sky.

During this exciting event, we were collecting your images and reactions online. 

Here are a few images of this celestial event...take a look:

This composite image, made from 4 frames, shows the International Space Station, with a crew of six onboard, as it transits the Sun at roughly five miles per second during a partial solar eclipse from, Northern Cascades National Park in Washington. Onboard as part of Expedition 52 are: NASA astronauts Peggy Whitson, Jack Fischer, and Randy Bresnik; Russian cosmonauts Fyodor Yurchikhin and Sergey Ryazanskiy; and ESA (European Space Agency) astronaut Paolo Nespoli.

DYK the bright clusters and nebulae of planet Earth's night sky are often named for flowers or insects? 

Though its wingspan covers over 3 light-years, NGC 6302: The Butterfly Nebula is no exception! With an estimated surface temperature of about 250,000 degrees C, the dying central star of this particular planetary nebula has become exceptionally hot, shining brightly in ultraviolet light but hidden from direct view by a dense torus of dust. This sharp close-up was recorded by the Hubble Space Telescope in 2009. The Hubble image data is reprocessed here, showing off the remarkable details of the complex planetary nebula.

Join the Party!

Celebrating the 100th Birthday of Our National Park Service!

When Yellowstone National Park became the first national park in the United States in 1872, there was no one to oversee its maintenance. From this beginning, a steady movement grew to embrace the country’s unique natural beauties.

Today, we can witness these natural beauties from space, courtesy of Expedition 48 commander, astronaut Jeff Williams, from aboard the International Space Station. 

Death Valley National Park

This is the commander’s view of Death Valley, taken from the station in early August 2016.

Everglades National Park

Williams captured the beauty of Florida Bay in the  Everglades National Park, focusing on  the Crocodile Sanctuary, a protected wildlife area. 

Glacier Bay

Sail down the Ice Ages at Glacier Bay National Park and Preserve.  From Tarr Inlet Tidewater glacier to Sitakaday Narrows.

Grand Canyon National Park

Grand indeed, here’s the Grand Canyon National Park seen from the International Space Station. Even from space, it took 13 pictures merged together to capture all 277 miles in this fly over.

Yosemite National Park

From visionary leaders of the movement, who worked to create and manage national parks like Teddy Roosevelt to Charles Young, the first African American park superintendent, Congress heeded the call and passed the National Park Service Organic Act, creating the National Park Service (NPS). One hundred years ago today, on August 25, 1916, President Woodrow Wilson signed the bill into law.

Our Spacecraft Have Discovered a New Magnetic Process in Space

Just as gravity is one key to how things move on Earth, a process called magnetic reconnection is key to how electrically-charged particles speed through space. Now, our Magnetospheric Multiscale mission, or MMS, has discovered magnetic reconnection – a process by which magnetic field lines explosively reconfigure – occurring in a new and surprising way near Earth.

Invisible to the eye, a vast network of magnetic energy and particles surround our planet — a dynamic system that influences our satellites and technology. The more we understand the way those particles move, the more we can protect our spacecraft and astronauts both near Earth and as we explore deeper into the solar system.

Earth’s magnetic field creates a protective bubble that shields us from highly energetic particles that stream in both from the Sun and interstellar space. As this solar wind bathes our planet, Earth’s magnetic field lines get stretched. Like elastic bands, they eventually release energy by snapping and flinging particles in their path to supersonic speeds.

That burst of energy is generated by magnetic reconnection. It’s pervasive throughout the universe — it happens on the Sun, in the space near Earth and even near black holes.

Scientists have observed this phenomenon many times in Earth’s vast magnetic environment, the magnetosphere. Now, a new study of data from our MMS mission caught the process occurring in a new and unexpected region of near-Earth space. For the first time, magnetic reconnection was seen in the magnetosheath — the boundary between our magnetosphere and the solar wind that flows throughout the solar system and one of the most turbulent regions in near-Earth space.

The four identical MMS spacecraft — flying through this region in a tight pyramid formation — saw the event in 3D. The arrows in the data visualization below show the hundreds of observations MMS took to measure the changes in particle motion and the magnetic field.

The data show that this event is unlike the magnetic reconnection we’ve observed before. If we think of these magnetic field lines as elastic bands, the ones in this region are much smaller and stretchier than elsewhere in near-Earth space — meaning that this process accelerates particles 40 times faster than typical magnetic reconnection near Earth. In short, MMS spotted a completely new magnetic process that is much faster than what we’ve seen before.

What’s more, this observation holds clues to what’s happening at smaller spatial scales, where turbulence takes over the process of mixing and accelerating particles. Turbulence in space moves in random ways and creates vortices, much like when you mix milk into coffee. The process by which turbulence energizes particles in space is still a big area of research, and linking this new discovery to turbulence research may give insights into how magnetic energy powers particle jets in space.

What’s Up for August 2016

What’s up for August? How to spot Mercury, Venus,  Mars, Jupiter and Saturn, as well as the and the annual Perseid meteor shower. 

Here are some highlights in this month’s nighttime skies as picked by astronomer Jane Houston Jones from our Jet Propulsion Laboratory.

Spot Venus, Mercury and Jupiter and the moon low on the western horizon about 45 minutes after sunset from August 4 through 7. On August 11, look in the south-southwest sky for a second planetary dance as Mars and Saturn are high and easy to see and they are joined by the moon.

The famous and reliably active Perseid meteor shower peaks in the morning hours of August 12. The moon, which paired up so nicely with Mars and Saturn on the 11, is bright enough to blot out some of the meteors, but lucky for you it sets about 1 a.m. on the morning of the 12, just at the peak time for the best Perseid viewing.

But wait, there are more planets, dwarf planets and an asteroid visible this month! Uranus and Neptune and dwarf planet Ceres are visible before dawn in the southern sky. Uranus is visible through binoculars but Neptune and Ceres require a telescope.

A Tour of Storms Across the Solar System

Earth is a dynamic and stormy planet with everything from brief, rumbling thunderstorms to enormous, raging hurricanes, which are some of the most powerful and destructive storms on our world. But other planets also have storm clouds, lightning — even rain, of sorts. Let’s take a tour of some of the unusual storms in our solar system and beyond.

Tune in May 22 at 3 p.m. for more solar system forecasting with NASA Chief Scientist Jim Green during the latest installment of NASA Science Live: https://www.nasa.gov/nasasciencelive.

1. At Mercury: A Chance of Morning Micrometeoroid Showers and Magnetic ‘Tornadoes’

Mercury, the planet nearest the Sun, is scorching hot, with daytime temperatures of more than 800 degrees Fahrenheit (about 450 degrees Celsius). It also has weak gravity — only about 38% of Earth's — making it hard for Mercury to hold on to an atmosphere.

Its barely there atmosphere means Mercury doesn’t have dramatic storms, but it does have a strange "weather" pattern of sorts: it’s blasted with micrometeoroids, or tiny dust particles, usually in the morning. It also has magnetic “tornadoes” — twisted bundles of magnetic fields that connect the planet’s magnetic field to space.

2. At Venus: Earth’s ‘Almost’ Twin is a Hot Mess

Venus is often called Earth's twin because the two planets are similar in size and structure. But Venus is the hottest planet in our solar system, roasting at more than 800 degrees Fahrenheit (430 degrees Celsius) under a suffocating blanket of sulfuric acid clouds and a crushing atmosphere. Add to that the fact that Venus has lightning, maybe even more than Earth. 

In visible light, Venus appears bright yellowish-white because of its clouds. Earlier this year, Japanese researchers found a giant streak-like structure in the clouds based on observations by the Akatsuki spacecraft orbiting Venus.

3. At Earth: Multiple Storm Hazards Likely

Earth has lots of storms, including thunderstorms, blizzards and tornadoes. Tornadoes can pack winds over 300 miles per hour (480 kilometers per hour) and can cause intense localized damage.

But no storms match hurricanes in size and scale of devastation. Hurricanes, also called typhoons or cyclones, can last for days and have strong winds extending outward for 675 miles (1,100 kilometers). They can annihilate coastal areas and cause damage far inland.

4. At Mars: Hazy with a Chance of Dust Storms

Mars is infamous for intense dust storms, including some that grow to encircle the planet. In 2018, a global dust storm blanketed NASA's record-setting Opportunity rover, ending the mission after 15 years on the surface.

Mars has a thin atmosphere of mostly carbon dioxide. To the human eye, the sky would appear hazy and reddish or butterscotch colored because of all the dust suspended in the air. 

5. At Jupiter: A Shrinking Icon

It’s one of the best-known storms in the solar system: Jupiter’s Great Red Spot. It’s raged for at least 300 years and was once big enough to swallow Earth with room to spare. But it’s been shrinking for a century and a half. Nobody knows for sure, but it's possible the Great Red Spot could eventually disappear.

6. At Saturn: A Storm Chasers Paradise

Saturn has one of the most extraordinary atmospheric features in the solar system: a hexagon-shaped cloud pattern at its north pole. The hexagon is a six-sided jet stream with 200-mile-per-hour winds (about 322 kilometers per hour). Each side is a bit wider than Earth and multiple Earths could fit inside. In the middle of the hexagon is what looks like a cosmic belly button, but it’s actually a huge vortex that looks like a hurricane.

Storm chasers would have a field day on Saturn. Part of the southern hemisphere was dubbed "Storm Alley" by scientists on NASA's Cassini mission because of the frequent storm activity the spacecraft observed there. 

7. At Titan: Methane Rain and Dust Storms

Earth isn’t the only world in our solar system with bodies of liquid on its surface. Saturn’s moon Titan has rivers, lakes and large seas. It’s the only other world with a cycle of liquids like Earth’s water cycle, with rain falling from clouds, flowing across the surface, filling lakes and seas and evaporating back into the sky. But on Titan, the rain, rivers and seas are made of methane instead of water.

Data from the Cassini spacecraft also revealed what appear to be giant dust storms in Titan’s equatorial regions, making Titan the third solar system body, in addition to Earth and Mars, where dust storms have been observed.

8. At Uranus: A Polar Storm

Scientists were trying to solve a puzzle about clouds on the ice giant planet: What were they made of? When Voyager 2 flew by in 1986, it spotted few clouds. (This was due in part to the thick haze that envelops the planet, as well as Voyager's cameras not being designed to peer through the haze in infrared light.) But in 2018, NASA’s Hubble Space Telescope snapped an image showing a vast, bright, stormy cloud cap across the north pole of Uranus.

9. At Neptune: Methane Clouds

Neptune is our solar system's windiest world. Winds whip clouds of frozen methane across the ice giant planet at speeds of more than 1,200 miles per hour (2,000 kilometers per hour) — about nine times faster than winds on Earth.

Neptune also has huge storm systems. In 1989, NASA’s Voyager 2 spotted two giant storms on Neptune as the spacecraft zipped by the planet. Scientists named the storms “The Great Dark Spot” and “Dark Spot 2.”

10. It’s Not Just Us: Extreme Weather in Another Solar System

Scientists using NASA’s Hubble Space Telescope made a global map of the glow from a turbulent planet outside our solar system. The observations show the exoplanet, called WASP-43b, is a world of extremes. It has winds that howl at the speed of sound, from a 3,000-degree-Fahrenheit (1,600-degree-Celsius) day side, to a pitch-black night side where temperatures plunge below 1,000 degrees Fahrenheit (500 degrees Celsius).

Discovered in 2011, WASP-43b is located 260 light-years away. The planet is too distant to be photographed, but astronomers detected it by observing dips in the light of its parent star as the planet passes in front of it.
