Repost from @WhiteHouse: Check out the American Flag seen on Flag Day, June 14, from the International Space Station's Cupola, the 360-degree Earth observation point. Research enabled by @StationCDRKelly's #YearInSpace on the @ISS will help scientists better understand how the human body reacts and adapts to long-duration spaceflight. This knowledge is critical as @NASA looks toward human missions deeper into the solar system, including to and from Mars, which could last 500 days or longer. It also carries potential benefits for humans on Earth, from helping patients recover after long periods of bed rest to improving monitoring for people whose bodies are unable to fight infections.; -
Repost from @WhiteHouse: "Another pass through #Aurora. The sun is very active today, apparently." —@StationCDRKelly on August 15 showing a photo of an aurora from the International Space Station The @ISS is a convergence of science, technology and human innovation that enables us to demonstrate new technologies and make research breakthroughs not possible on Earth. It has been continuously occupied since November 2000. Since then, it has been visited by more than 200 people and a variety of international and commercial spacecraft. The space station remains the springboard to @NASA's next giant leap in exploration, including future missions to Mars. #YearInSpace; -
Repost from @WhiteHouse: Here's a photo of @StationCDRKelly aboard the International Space Station that's never been seen before on @Instagram! @NASA hopes that the knowledge gained on Astronaut Scott Kelly's #YearInSpace mission on the @ISS will benefit the Earth and that the data collected will help send humans to new destinations, supporting the next generation of space exploration. That's why to add in another dynamic to the mission: researchers are conducting “twin studies” between Scott and his brother @ShuttleCDRKelly comparing the subtle effects and changes between spaceflight and Earth. Scott and Mark Kelly are twin brothers with almost identical genetics, but they'll be in different environments for one year.; -
Repost from @WhiteHouse: "#GoodMorning to those in the western #USA. Looks like there's a lot going on down there." —@StationCDRKelly on August 10th Today marks the midpoint of Astronaut Scott Kelly's #YearInSpace aboard the International Space Station. Almost everything we know about living in space ends at six months, so as he heads into the second half of his mission, he's pushing the edge of our scientific understanding. Follow along today as @NASA takes over our account with photos from the first half of Scott's #YearInSpace on the @ISS.; -
Artist concept of an auroral display on a brown dwarf: Mysterious objects called brown dwarfs are sometimes called "failed stars." They are too small to fuse hydrogen in their cores, the way most stars do, but also too large to be classified as planets. But a new study in the journal Nature suggests they succeed in creating powerful auroral displays, similar to the kind seen around the magnetic poles on Earth. If you could see an aurora on a brown dwarf, it would be a million times brighter than an aurora on Earth.

Rocks Here Sequester Some of Mars' Early Atmosphere This view combines information from two instruments on NASA's Mars Reconnaissance Orbiter to map color-coded composition over the shape of the ground in a small portion of the Nili Fossae plains region of Mars' northern hemisphere. This site is part of the largest known carbonate-rich deposit on Mars. In the color coding used for this map, green indicates a carbonate-rich composition, brown indicates olivine-rich sands, and purple indicates basaltic composition. Carbon dioxide from the atmosphere on early Mars reacted with surface rocks to form carbonate, thinning the atmosphere by sequestering the carbon in the rocks.

The arrangement of the spiral arms in the galaxy Messier 63, seen here in an image from the Hubble Space Telescope, recall the pattern at the center of a sunflower. So the nickname for this cosmic object — the Sunflower Galaxy — is no coincidence. Galactic arms, sunflowers and whirlpools are only a few examples of nature’s apparent preference for spirals. For galaxies like Messier 63 the winding arms shine bright because of the presence of recently formed, blue–white giant stars and clusters, readily seen in this Hubble image.

A small, but complex mass of solar material gyrated and spun about over the course of 40 hours above the surface of the sun on Sept. 1-3, 2015. It was stretched and pulled back and forth by powerful magnetic forces in this sequence captured by our Solar Dynamics Observatory, or SDO. The temperature of the ionized iron particles observed in this extreme ultraviolet wavelength of light was about 5 million degrees Fahrenheit. SDO captures imagery in many wavelengths, each of which represents different temperatures of material, and each of which highlights different events on the sun. Each wavelength is typically colorized in a pre-assigned color. Wavelengths of 335 Angstroms, such as are represented in this picture, are colorized in blue.

New close-up images of Pluto reveal a bewildering variety of surface features that have scientists reeling because of their range and complexity. This synthetic perspective view of Pluto, based on the latest high-resolution images to be downlinked from our New Horizons spacecraft, shows what you would see if you were approximately 1,100 miles (1,800 kilometers) above Pluto's equatorial area, looking northeast over the dark, cratered, informally named Cthulhu Regio toward the bright, smooth, expanse of icy plains informally called Sputnik Planum. The entire expanse of terrain seen in this image is 1,100 miles (1,800 kilometers) across. The images were taken as New Horizons flew past Pluto on July 14, 2015, from a distance of 50,000 miles (80,000 kilometers).

Mysterious bright spots are seen here in greater detail. This image, made using images taken by our Dawn spacecraft, shows Occator crater on dwarf planet Ceres, home to a collection of intriguing bright spots. The bright spots are much brighter than the rest of Ceres' surface, and tend to appear overexposed in most images. This view is a composite of two images of Occator: one using a short exposure that captures the detail in the bright spots, and one where the background surface is captured at normal exposure.

Before drifting off to sleep on Saturday, Sept. 5, astronaut Scott Kelly (@stationcdrkelly) aboard the International Space Station posted this image and wrote, "#goodnight #Earth! Make me proud and I'll try and do the same. #YearInSpace." Kelly is living and working off the Earth, for the Earth aboard the station for a yearlong mission. Traveling the world about 250 miles above the Earth, and at 17,500 mph, he circumnavigates the globe more than a dozen times a day. Image Credit: NASA #nasa #space #iss #spacestation #sun; -

Summer Vacation: NASA astronaut Scott Kelly and his Russian crewmates Gennady Padalka and Mikhail (Misha) Kornienko took a road trip of sorts from the International Space Station after a little more than five months of their stay. They left their orbital home for a 20-minute get away to move their spacecraft. They undocked their Soyuz that brought them to the space station back in late March from one International Space Station module to another, clearing a module for the arrival of a new crew. It's the first time in nearly two years since nine crew members are aboard the station simultaneously. It's a full house.

Peering into the Heart of a Galactic Maelstrom: This Hubble Space Telescope image shows a spiral galaxy just over 35 million light-years away in the constellation of Leo (The Lion). It is of about the same mass and size as the Milky Way. The galaxy resembles a giant maelstrom of glowing gas, rippled with dark dust that swirls inwards towards the nucleus. Messier 96 is a very asymmetric galaxy; its dust and gas are unevenly spread throughout its weak spiral arms, and its core is not exactly at the galactic center. Its arms are also asymmetrical, thought to have been influenced by the gravitational pull of other galaxies within the same group.

At Saturn, One of These Rings is not like the Others: When the sun set on Saturn's rings in August 2009, scientists on our Cassini mission were watching closely. It was the equinox -- one of two times in the Saturnian year when the sun illuminates the planet's enormous ring system edge-on. The event provided an extraordinary opportunity for the orbiting Cassini spacecraft to observe short-lived changes in the rings that reveal details about their nature. In a recent study, a team of Cassini scientists reported that one section of the rings appears to have been running a slight fever during equinox. The higher-than-expected temperature provided a unique window into the interior structure of ring particles not usually available to scientists. This result is fascinating because it suggests that the middle of Saturn's A ring may be much younger than the rest of the rings. Other parts of the rings may be as old as Saturn itself.
