Expedition 52 Begins Aboard Space Station

When humans launch to the International Space Station, they are members of expeditions. An expedition is long duration stay on the space station. The first expedition started when the crew docked to the station on Nov. 2, 2000.

Expedition 52 began in June 2017 aboard the orbiting laboratory and will end in September 2017. 

FUN FACT: Each Expedition begins with the undocking of the spacecraft carrying the departing crew from the previous Expedition. So Expedition 52 began with the undocking of the Soyuz MS-03 spacecraft that brought Expedition 51 crew members Oleg Novitskiy and Thomas Pesquet back to Earth, leaving NASA astronauts Peggy Whitson and Jack Fischer and Roscosmos cosmonaut Fyodor Yurchikhin aboard the station to await the arrival of the rest of the Expedition 52 crew in July.

This expedition includes dozens of out of this world science investigations and a crew that takes #SquadGoals to a whole new level. 

Take a look below to get to know the crew members and some of the science that will occur during the space station’s 52nd expedition.

What will the crew be doing during Expedition 52?

In addition to one tentatively planned spacewalk, crew members will conduct scientific investigations that will demonstrate more efficient solar arrays, study the physics of neutron stars, study a new drug to fight osteoporosis and study the adverse effects of prolonged exposure to microgravity on the heart.

Roll-Out Solar Array (ROSA)

Solar panels are an efficient way to generate power, but they can be delicate and large when used to power a spacecraft or satellites. They are often tightly stowed for launch and then must be unfolded when the spacecraft reaches orbit.

The Roll-Out Solar Array (ROSA), is a solar panel concept that is lighter and stores more compactly for launch than the rigid solar panels currently in use. ROSA has solar cells on a flexible blanket and a framework that rolls out like a tape measure.  

Neutron Star Interior Composition Explored (NICER)

Neutron stars, the glowing cinders left behind when massive stars explode as supernovas, are the densest objects in the universe, and contain exotic states of matter that are impossible to replicate in any ground lab.

The Neutron Star Interior Composition Explored (NICER) payload, affixed to the exterior of the space station, studies the physics of these stars, providing new insight into their nature and behavior.

Systemic Therapy of NELL-1 for Osteoporosis (Rodent Research-5)

When people and animals spend extended periods of time in space, they experience bone density loss. The Systemic Therapy of NELL-1 for osteoporosis (Rodent Research-5) investigation tests a new drug that can both rebuild bone and block further bone loss, improving health for crew members.

Fruit Fly Lab-02

Exposure to reduced gravity environments can result in cardiovascular changes such as fluid shifts, changes in total blood volume, heartbeat and heart rhythm irregularities, and diminished aerobic capacity. The Fruit Fly Lab-02 study will use the fruit fly (Drosophila melanogaster) to better understand the underlying mechanisms responsible for the adverse effects of prolonged exposure to microgravity on the heart.

Watch their progress HERE!

Expedition 52 Mission Patch 

Our planet is shown surrounded by an imaginary constellation shaped like a house, depicting the theme of the patch: “The Earth is our home.” It is our precious cradle, to be preserved for all future generations. The house of stars just touches the Moon, acknowledging the first steps we have already taken there, while Mars is not far away, just beyond the International Space Station, symbolized by the Roman numeral “LII,” signifying the expedition number. 

The planets Saturn and Jupiter, seen orbiting farther away, symbolize humanity’s exploration of deeper space, which will begin soon. A small Sputnik is seen circling the Earth on the same orbit with the space station, bridging the beginning of our cosmic quest till now: Expedition 52 will launch in 2017, sixty years after that first satellite. Two groups of crew names signify the pair of Soyuz vehicles that will launch the astronauts of Expedition 52 to the Station.

What are the most important skills an astronaut should have m?

First of all, the basic requirement is a bachelor’s degree in a STEM field, and 3 years of experience (which can also be substituted for by an advanced degree). Other than that, operational experience (things with a technical/active/hands on nature like flying airplanes, SCUBA diving, taking things apart and putting them back together, basic fix-it skills, etc. etc.) is very important, as this is an integral aspect of every day of a space mission.  What we call “expeditionary skills” are also essential, basically the types of things you try to instill in your children, like how to play nicely with others, self care, team care, etc.  I like to think about this on the lines of a camping trip and who you would like to have along with you . . .someone that is competent and can take good care of themselves and their equipment, someone that contributes to the team and helps with group tasks, someone that is good natured and pleasant to be around, etc., someone fun!  These things are increasingly important now that we are regularly doing long duration missions (typical International Space Station mission is 6 months).  Experience living in extreme/remote/isolated environments with small teams is also useful, as it is similar to what we experience as astronauts.     

How does flying feel?

Amazing Earth: Satellite Images from 2020

In the vastness of the universe, the life-bringing beauty of our home planet shines bright. During this tumultuous year, our satellites captured some pockets of peace, while documenting data and striking visuals of unprecedented natural disasters. As 2020 comes to a close, we’re diving into some of the devastation, wonders, and anomalies this year had to offer. 

NASA’s fleet of Earth-observing satellites and instruments on the International Space Station unravel the complexities of the blue marble from a cosmic vantage point. These robotic scientists orbit our globe constantly, monitoring and notating changes, providing crucial information to researchers here on the ground. 

Take a glance at 2020 through the lens of NASA satellites:

 A Delta Oasis in Southeastern Kazakhstan

Seen from space, the icy Ili River Delta contrasts sharply with the beige expansive deserts of southeastern Kazakhstan.

When the Operational Land Imager (OLI) on Landsat 8 acquired this natural-color image on March 7, 2020, the delta was just starting to shake off the chill of winter. While many of the delta’s lakes and ponds were still frozen, the ice on Lake Balkhash was breaking up, revealing swirls of sediment and the shallow, sandy bed of the western part of the lake.

The expansive delta and estuary is an oasis for life year round. Hundreds of plant and animal species call it home, including dozens that are threatened or endangered. 

Fires and Smoke Engulf Southeastern Australia

A record-setting and deadly fire season marred the beginning of the year in Australia. Residents of the southeastern part of the country told news media about daytime seeming to turn to night, as thick smoke filled the skies and intense fires drove people from their homes. 

This natural-color image of Southeastern Australia was acquired on January 4, 2020, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. The smoke has a tan color, while clouds are bright white. It is likely that some of the white patches above the smoke are pyrocumulonimbus clouds—clouds created by the convection and heat rising from a fire.

Nighttime Images Capture Change in China

A team of scientists from NASA’s Goddard Space Flight Center (GSFC) and Universities Space Research Association (USRA) detected signs of the shutdown of business and transportation around Hubei province in central China. As reported by the U.S. State Department, Chinese authorities suspended air, road, and rail travel in the area and placed restrictions on other activities in late January 2020 in response to the COVID-19 outbreak in the region.

A research team analyzed images of Earth at night to decipher patterns of energy use, transportation, migration, and other economic and social activities. Data for the images were acquired with the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA–NASA Suomi NPP satellite (launched in 2011) and processed by GSFC and USRA scientists. VIIRS has a low-light sensor—the day/night band—that measures light emissions and reflections. This capability has made it possible to distinguish the intensity, types, and sources of lights and to observe how they change.

The Parched Paraná River

Though a seemingly serene oasis from above, there is more to this scene than meets the eye. On July 3, 2020, the Operational Land Imager (OLI) on Landsat 8 captured this false-color image of the river near Rosario, a key port city in Argentina. The combination of shortwave infrared and visible light makes it easier to distinguish between land and water. A prolonged period of unusually warm weather and drought in southern Brazil, Paraguay, and northern Argentina dropped the Paraná River to its lowest water levels in decades. The parched river basin has hampered shipping and contributed to an increase in fire activity in the delta and floodplain.

The drought has affected the region since early 2020, and low water levels have grounded several ships, and many vessels have had to reduce their cargo in order to navigate the river. With Rosario serving as the distribution hub for much of Argentina’s soy and other farm exports, low water levels have caused hundreds of millions of dollars in losses for the grain sector, according to news reports.

Historic Fires Devastate the U.S. Pacific Coast

Climate and fire scientists have long anticipated that fires in the U.S. West would grow larger, more intense, and more dangerous. But even the most experienced among them have been at a loss for words in describing the scope and intensity of the fires burning in West Coast states during September 2020.

Lightning initially triggered many of the fires, but it was unusual and extreme meteorological conditions that turned some of them into the worst conflagrations in the region in decades. 

Throughout the outbreak, sensors like the Visible Infrared Imaging Radiometer Suite (VIIRS) and the Ozone Mapping and Profiler Suite (OMPS) on the NOAA-NASA Suomi NPP satellite collected daily images showing expansive, thick plumes of aerosol particles blowing throughout the U.S. West on a scale that satellites and scientists rarely see. 

This image shows North America on September 9th, 2020, as a frontal boundary moved into the Great Basin and produced very high downslope winds along the mountains of Washington, Oregon, and California. The winds whipped up the fires, while a pyrocumulus cloud from the Bear fire in California injected smoke high into the atmosphere. The sum of these events was an extremely thick blanket of smoke along the West Coast.

The Sandy Great Bahama Bank

Though the bright blues of island waters are appreciated by many from a sea-level view, their true beauty is revealed when photographed from space. The underwater masterpiece photographed above is composed of sand dunes off the coast of the Bahamas. 

The Great Bahama Bank was dry land during past ice ages, but it slowly submerged as sea levels rose. Today, the bank is covered by water, though it can be as shallow as two meters (seven feet) deep in places. The wave-shaped ripples in the image are sand on the seafloor. The curves follow the slopes of the dunes, which were likely shaped by a fairly strong current near the sea bottom. Sand and seagrass are present in different quantities and depths, giving the image it’s striking range of blues and greens.

This image was captured on February 15th, 2020, by Landsat 8, whose predecessor, Landsat 7, was the first land-use satellite to take images over coastal waters and the open ocean. Today, many satellites and research programs map and monitor coral reef systems, and marine scientists have a consistent way to observe where the reefs are and how they are faring. 

Painting Pennsylvania Hills

Along with the plentiful harvest of crops in North America, one of the gifts of Autumn is the gorgeous palette of colors created by the chemical transition and fall of leaves from deciduous trees. 

The folded mountains of central Pennsylvania were past peak leaf-peeping season but still colorful when the Operational Land Imager (OLI) on the Landsat 8 satellite passed over on November 9, 2020. The natural-color image above shows the hilly region around State College, Pennsylvania overlaid on a digital elevation model to highlight the topography of the area.

The region of rolling hills and valleys is part of a geologic formation known as the Valley and Ridge Province that stretches from New York to Alabama. These prominent folds of rock were mostly raised up during several plate tectonic collisions and mountain-building episodes in the Ordovician Period and later in the creation of Pangea—when what is now North America was connected with Africa in a supercontinent. Those events created the long chain of the Appalachians, one of the oldest mountain ranges in the world. 

A Dangerous Storm in the Night

Ominous and looming, a powerful storm hovered off the US coastline illuminated against the dark night hues. 

The Visible Infrared Imaging Radiometer Suite (VIIRS) on NOAA-20 acquired this image of Hurricane Laura at 2:20 a.m. Central Daylight Time on August 26, 2020. Clouds are shown in infrared using brightness temperature data, which is useful for distinguishing cooler cloud structures from the warmer surface below. That data is overlaid on composite imagery of city lights from NASA’s Black Marble dataset.

Hurricane Laura was among the ten strongest hurricanes to ever make landfall in the United States. Forecasters had warned of a potentially devastating storm surge up to 20 feet along the coast, and the channel might have funneled that water far inland. It did not. The outcome was also a testament to strong forecasting and communication by the National Hurricane Center and local emergency management authorities in preparing the public for the hazards.

A Windbreak Grid in Hokkaido

From above, the Konsen Plateau in eastern Hokkaido offers a remarkable sight: a massive grid that spreads across the rural landscape like a checkerboard, visible even under a blanket of snow. Photographed by the Operational Land Imager (OLI) on Landsat 8, this man-made design is not only aesthetically pleasing, it’s also an agricultural insulator. 

The strips are forested windbreaks—180-meter (590-foot) wide rows of coniferous trees that help shelter grasslands and animals from Hokkaido’s sometimes harsh weather. In addition to blocking winds and blowing snow during frigid, foggy winters, they help prevent winds from scattering soil and manure during the warmer months in this major dairy farming region of Japan. 

Shadows from a Solar Eclipse

Formidable, rare, and awe-inspiring — the first and only total solar eclipse of 2020 occurred on December 14, with the path of totality stretching from the equatorial Pacific to the South Atlantic and passing through southern Argentina and Chile as shown in the lower half of the image above. The Advanced Baseline Imager (ABI) on Geostationary Operational Environmental Satellite 16 (GOES-16) captured these images of the Moon’s shadow crossing the face of Earth. 

The “path of totality” (umbral path) for the eclipse was roughly 90 kilometers (60 miles) wide and passed across South America from Saavedra, Chile, to Salina del Eje, Argentina. While a total eclipse of the Sun occurs roughly every 18 months, seeing one from any particular location on Earth is rare. On average, a solar eclipse passes over the same parcel of land roughly every 375 years. The next total solar eclipse will occur on December 4, 2021 over Antarctica, and its next appearance over North America is projected for April 8, 2024.

Our Weird and Wonderful Galaxy of Black Holes

Black holes are hard to find. Like, really hard to find. They are objects with such strong gravity that light can’t escape them, so we have to rely on clues from their surroundings to find them.

When a star weighing more than 20 times the Sun runs out of fuel, it collapses into a black hole. Scientists estimate that there are tens of millions of these black holes dotted around the Milky Way, but so far we’ve only identified a few dozen. Most of those are found with a star, each circling around the other. Another name for this kind of pair is a binary system.That’s because under the right circumstances material from the star can interact with the black hole, revealing its presence. 

The visualization above shows several of these binary systems found in our Milky Way and its neighboring galaxy. with their relative sizes and orbits to scale. The video even shows each system tilted the way we see it here from our vantage point on Earth. Of course, as our scientists gather more data about these black holes, our understanding of them may change.   

If the star and black hole orbit close enough, the black hole can pull material off of its stellar companion! As the material swirls toward the black hole, it forms a flat ring called an accretion disk. The disk gets very hot and can flare, causing bright bursts of light.

V404 Cygni, depicted above, is a binary system where a star slightly smaller than the Sun orbits a black hole 10 times its mass in just 6.5 days. The black hole distorts the shape of the star and pulls material from its surface. In 2015, V404 Cygni came out of a 25-year slumber, erupting in X-rays that were initially detected by our Swift satellite. In fact, V404 Cygni erupts every couple of decades, perhaps driven by a build-up of material in the outer parts of the accretion disk that eventually rush in. 

In other cases, the black hole’s companion is a giant star with a strong stellar wind. This is like our Sun’s solar wind, but even more powerful. As material rushes out from the companion star, some of it is captured by the black hole’s gravity, forming an accretion disk.

A famous example of a black hole powered by the wind of its companion is Cygnus X-1. In fact, it was the first object to be widely accepted as a black hole! Recent observations estimate that the black hole’s mass could be as much as 20 times that of our Sun. And its stellar companion is no slouch, either. It weighs in at about 40 times the Sun.

We know our galaxy is peppered with black holes of many sizes with an array of stellar partners, but we've only found a small fraction of them so far. Scientists will keep studying the skies to add to our black hole menagerie.

Not all galaxies are lonely. Some have galaxy squads. ⁣

NGC 1706, captured in this image by our Hubble Space Telescope, belongs to something known as a galaxy group, which is just as the name suggests — a group of up to 50 galaxies which are gravitationally bound and relatively close to each other. ⁣

Our home galaxy, the Milky Way, has its own squad — known as the Local Group, which also contains the Andromeda galaxy, the Large and Small Magellanic clouds and the Triangulum galaxy.
