We selected proposals for two new instruments that will observe changes in global vegetation from the International Space Station. The sensors will give scientists new ways to see how forests and ecosystems are affected by changes in climate or land use change. This image of the Amazon rainforest is from a 2010 global map of the height of the world’s forests based on multiple satellite datasets.

Liftoff! The European Space Agency’s (ESA) fifth and final Automated Transfer Vehicle (ATV-5) launched Tuesday atop an Ariane 5 rocket from Kourou, French Guiana, at 7:47 p.m. EDT. The ATV-5 will take a two week trip to the International Space Station docking to the Zvezda service module on Aug. 12 at 9:43 a.m. with 7 tons of science, food, fuel and supplies. En route to the station, the Georges Lemaitre will pass 3.9 miles beneath the space station Aug. 8 so European flight controllers can test new rendezvous sensors. Engineers may use the new sensors in the design and manufacture of future European spacecraft. After the “fly-under”, the ATV-5 will pass in front, above and behind the station for the final four days of its rendezvous with Zvezda. Credit: ESA–S.

Go get your 3-D glasses, you know, the blue-red ones with the red lens on the left. This stereo view from our Mars Exploration Rover Opportunity will appear three-dimensional. The view combines several images taken by Opportunity's Pancam and was obtained on the rover's 3,644th Martian day (sol) of exploration (April 24, 2014). Part of the rover is visible at bottom, including its rear solar arrays and low-gain antenna - the antenna appears incomplete here due to combining images with different camera pointings. Each day's drive by Opportunity sets a new record for longest travel on wheels on a world other than Earth.

Geysers on icy Saturn moon! Scientists using mission data from our Cassini spacecraft have identified 101 distinct geysers erupting on Saturn's icy moon Enceladus, suggesting it is possible for liquid water to reach moon's surface from its underground sea. This view looks across the geyser basin of Saturn's moon Enceladus, along fractures spewing water vapor and ice particles into space.

Caught between the sun and our Solar Dynamics Observatory... the moon. The phenomenon, called a lunar transit, was observed on July 26, 2014, from 10:57 a.m. to 11:42 a.m. EDT. This happens approximately twice a year, causing a partial solar eclipse that can only be seen from SDO's point of view. Images of the eclipse show a crisp lunar horizon, because the moon has no atmosphere that would distort light. Image Credit: NASA #space #nasa #sun #sdo #science #moon;

Hubble Serves a Slice of Stars The thin, glowing streak slicing across this image cuts a lonely figure, with only a few foreground stars and galaxies in the distant background for company. However, this is all a case of perspective; lying out of frame is another nearby spiral. Together, these two galaxies make up a pair, moving through space together and keeping one another company. The subject of this Hubble image is called NGC 3501, with NGC 3507 as its out-of-frame companion. The two galaxies look very different — another example of the importance of perspective. NGC 3501 appears edge-on, giving it an elongated and very narrow appearance. Its partner, however, looks very different indeed, appearing face-on and giving us a fantastic view of its barred swirling arms. While similar arms may not be visible in this image of NGC 3501, this galaxy is also a spiral — although it is somewhat different from its companion. While NGC 3507 has bars cutting through its center, NGC 3501 does not. Instead, it's loosely wound spiral arms all originate from its center. The bright gas and stars that make up these arms can be seen here glowing brightly, mottled by the dark dust lanes that trace across the galaxy.

Yesterday, astronaut Reid Wiseman shared this image of Earth showing Italy at night from the International Space Station tweeting "I looked on in awe and was rendered speechless by so much beauty." The Expedition 40 crew has been hard at work 260 miles above us in the floating laboratory. They set a new record for #ISS research completed in a week -- 82 hours -- this past week.

Peering through the layers: This collage of images shows an active region on the Sun taken at almost the same time in extreme ultraviolet light by NASA's Solar Dynamics Observatory on July 24, 2014 at about 17:56 UTC. The layers are arranged clockwise from the upper left by temperature of plasma being imaged. This arrangement also correlates with the distance above the Sun's surface, going from lowest to highest. Different features of the active region appear quite differently in the four images: each one helps to provide scientists with more information about the Sun's processes.

The six-person Expedition 40 crew wrapped up a productive week of cargo vehicle traffic and science aboard the International Space Station with more medical studies, physics and robotics on Friday. Meanwhile, preparations continue for the launch of another station resupply vehicle next week. Seen here is one of the more spectacular scenes of the Aurora Borealis that was photographed by one of the space station crew members aboard the International Space Station from an altitude of approximately 223 nautical miles.

The Sunshield on NASA's James Webb Space Telescope is the largest part of the observatory—five layers of thin membrane that must unfurl reliably in space to precise tolerances. Last week, for the first time, engineers stacked and unfurled a full-sized test unit of the Sunshield and it worked perfectly. The Sunshield is about the length of a tennis court, and will be folded up like an umbrella around the Webb telescope’s mirrors and instruments during launch. Once it reaches its orbit, the Webb telescope will receive a command from Earth to unfold, and separate the Sunshield's five layers into their precisely stacked arrangement with its kite-like shape.

Comet C/2013 UQ4 (Catalina) has been observed by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft just one day after passing through its closest approach to the sun. The comet is seen glowing brightly in infrared wavelengths on July 7, 2014, with a dust tail streaking more than 62,000 miles (100,000 kilometers) across the sky. Its spectacular activity is driven by the vaporization of ice that has been preserved from the time of planet formation 4.5 billion years ago. C/2013 UQ4 takes more than 450 years to orbit the sun once and spends most of its time far away at very low temperatures. Its orbit is also retrograde, which means that the comet moves around the sun in the opposite direction to the planets and asteroids. The comet was originally thought to be an asteroid, as it appeared inactive when discovered by the Catalina Sky Survey on October 23, 2013. NEOWISE also observed the comet to be inactive on New Year's Eve, 2013, but since then the comet has become highly active, allowing astronomers around the world to observe it. The comet's activity should decline as it once again returns to the cold recesses of space. Image Credit: NASA/JPL-Caltech #nasa #neowise #comet #asteroid #infrared #stars #space; -
As seen on @CBSThisMorning, which is posting some of our images this week: Four #astronauts are living 62 feet below the surface of the Atlantic Ocean for nine days this summer. The crew members of the NASA Extreme Environment Mission Operations (NEEMO) 18 project, which began Monday, July 21, will test technologies and training techniques for use aboard the International Space Station and long-duration #exploration missions. Mission objectives focus on behavioral health and performance, human health issues, and habitability. Seen here is Jeanette Epps diving during a simulated spacewalk using the core drill. A drill like this could be used on other planetary surfaces to collect core samples. #NEEMO is helping test techniques that pave the #PathToMars as part of #NASA's #NextGiantLeap -- sending astronauts to the Red Planet.

45 years ago now: #Apollo11 splashes down bringing Neil Armstrong, Buzz Aldrin & Michael Collins home to Earth. This past weekend marks 45 years ago that Neil Armstrong took the small step onto the surface of the moon that changed the course of history. The years that followed saw a Space Age of scientific, technological and human research, on which we have built the modern era. We stand on a new horizon, poised to take the next giant leap—deeper into the solar system. The Apollo missions blazed a path for human exploration to the moon and today we are extending that path to near-Earth asteroids, Mars and beyond.

As seen on @CBSThisMorning, which is posting some of our images this week - Earth. Aboard the International Space Station, astronaut Reid Wiseman photographed this image and wrote, “Thin silver polar #mesospheric clouds. The beauty from up here far exceeds the camera's ability to capture it.” Every day on the space station, scientific research is being conducted to prepare astronauts to venture farther into the solar system than ever before and provide real benefits to life on Earth. The station is the largest human-made object ever to orbit the Earth. It is so large that it can be seen drifting overhead with the unaided eye, and is frequently imaged from the ground in picturesque fashion. You can sign up for alerts when the space station will be flying over you by visiting: http://www.spotthestation.nasa.gov The station is helping pave the path to Mars for our next giant leap -- sending astronauts to the Red Planet.
