Soyuz Spacecraft Rolled Out For Launch of One-Year Crew
The Soyuz TMA-16M spacecraft is seen after having rolled out by train to the launch pad at the Baikonur Cosmodrome, Kazakhstan, Wednesday, March 25, 2015. NASA astronaut Scott Kelly and Russian cosmonauts Mikhail Kornienko and Gennady Padalka of the Russian Federal Space Agency (Roscosmos) are scheduled to launch to the International Space Station in the Soyuz at 3:42 p.m. EDT, Friday, March 27 (March 28, Kazakh time). As the one-year crew, Kelly and Kornienko will return to Earth on the Soyuz TMA-18M in March 2016. Most expeditions to the space station last four to six months. By doubling the length of this mission, researchers hope to better understand how the human body reacts and adapts to long-duration spaceflight. This knowledge is critical as NASA looks toward human journeys deeper into the solar system, including to and from Mars, which could last 500 days or longer.

This NASA/ESA Hubble Space Telescope image shows an edge-on view of the spiral galaxy NGC 5023. Due to its orientation we cannot appreciate its spiral arms, but we can admire the elegant profile of its disk. The galaxy lies over 30 million light-years away from us. NGC 5023 is part of the M51 group of galaxies. The brightest galaxy in this group is Messier 51, the Whirlpool Galaxy, which has been captured by Hubble many times. NGC 5023 is less fond of the limelight and seems rather unsociable in comparison — it is relatively isolated from the other galaxies in the group. Astronomers are particularly interested in the vertical structure of disks like these. By analyzing the structure above and below the central plane of the galaxy they can make progress in understanding galaxy evolution. Astronomers are able to analyze the distribution of different types of stars within the galaxy and their properties, in particular how well evolved they are on the Hertzsprung–Russell Diagram — a scatter graph of stars that shows their evolution. NGC 5023 is one of six edge-on spiral galaxies observed as part of a study using Hubble’s Advanced Camera for Surveys. They study this vertical distribution and find a trend which suggests that heating of the disc plays an important role in producing the stars seen away from the plane of the galaxy. In fact, NGC 5023 is pretty popular when it comes to astronomers, despite its unsociable behavior. The galaxy is also one of 14 disk galaxies that are part of the GHOSTS survey — a survey which uses Hubble data to study galaxy halos, outer disks and star clusters. It is the largest study to date of star populations in the outskirts of disk galaxies. The incredible sharp sight of Hubble has allowed scientist to count more than 30,000 individual bright stars in this image. This is only a small fraction of the several billion stars that this galaxy contains, but the others are too faint to detect individually even with Hubble.

Pushing the Boundaries of Propelling Deep Space Missions
Engineers at NASA’s Glenn Research Center are advancing the propulsion system that will propel the first ever mission to redirect an asteroid for astronauts to explore in the 2020s. NASA's Asteroid Redirect Mission will test a number of new capabilities, like advanced Solar Electric Propulsion (SEP), needed for future astronaut expeditions into deep space, including to Mars. The Hall thruster is part of an SEP system that uses 10 times less propellant than equivalent chemical rockets. In a recent test, engineers from Glenn and the Jet Propulsion Laboratory, using a Glenn vacuum chamber to simulate the space environment, successfully tested a new, higher power Hall thruster design, which is more efficient and has longer life. “We proved that this thruster can process three times the power of previous designs and increase efficiency by 50 percent,” said Dan Herman, Electric Propulsion Subsystem lead. Hall thrusters trap electrons in a magnetic field and use them to ionize the onboard propellant. The magnetic field also generates an electric field that accelerates the charged ions creating an exhaust plume of plasma that pushes the spacecraft forward. This method delivers cost-effective, safe and highly efficient in-space propulsion for long duration missions. In addition to propelling an asteroid mission, this new thruster could be used to send large amounts of cargo, habitats and other architectures in support of human missions to Mars.

Typhoon Maysak strengthened into a super typhoon on March 31, reaching Category 5 hurricane status on the Saffir-Simpson Wind Scale. ESA Astronaut Samantha Cristoforetti captured this image while flying over the weather system on board the International Space Station. The Tropical Rainfall Measuring Mission (TRMM) and Global Precipitation Measurement (GPM) satellites, both co-managed by NASA and the Japan Aerospace Exploration Agency, captured rainfall and cloud data that revealed heavy rainfall and high thunderstorms in the strengthening storm. The TRMM satellite has been collecting valuable scientific data since November 1997. Early on March 30, the satellite collected rainfall data as it flew directly above Maysak at 04:14 UTC (12:14 a.m. EDT) when maximum sustained winds were near 85 knots (98 mph). Rainfall data was collected by TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments and showed heaviest rainfall southwest of the center, and in fragmented bands of thunderstorms northeast of the center. In both of those places rainfall was in excess of 50 mm/2 inches per hour. More information. Image Credit: ESA/NASA/Samantha Cristoforetti (More at NASA Picture of The Day)
Curiosity Sees Prominent Mineral Veins on Mount Sharp, Mars
This view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows a network of two-tone mineral veins at an area called "Garden City" on lower Mount Sharp. The veins combine light and dark material. The veins at this site jut to heights of up to about 2.5 inches (6 centimeters) above the surrounding rock, and their widths range up to about 1.5 inches (4 centimeters). Figure 1 includes a 30-centimeter scale bar (about 12 inches). Mineral veins such as these form where fluids move through fractured rocks, depositing minerals in the fractures and affecting chemistry of the surrounding rock. In this case, the veins have been more resistant to erosion than the surrounding host rock. This scene is a mosaic combining 28 images taken with Mastcam's right-eye camera, which has a telephoto lens with a focal length of 100 millimeters. The component images were taken on March 18, 2015, during the 929th Martian day, or sol, of Curiosity's work on Mars. The color has been approximately white-balanced to resemble how the scene would appear under daytime lighting conditions on Earth. Malin Space Science Systems, San Diego, built and operates the rover's Mastcam. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington. JPL designed and built the project's Curiosity rover.

Experimental Wing Tests Electric Propulsion Technologies
Leading Edge Asynchronous Propeller Technology (LEAPTech) project researchers at NASA's Armstrong Flight Research Center are performing ground testing of a 31-foot-span, carbon composite wing section with 18 electric motors. The LEAPTech project will test the premise that tighter propulsion-airframe integration, made possible with electric power, will deliver improved efficiency and safety, as well as environmental and economic benefits. The experimental wing, called the Hybrid-Electric Integrated Systems Testbed (HEIST), is mounted on a specially modified truck. Testing on the mobile ground rig assembly will provide valuable data and risk reduction applicable to future flight research. Instead of being installed in a wind tunnel, the HEIST wing section will remain attached to load cells on a supporting truss while the vehicle is driven at speeds up to 70 miles per hour across a dry lakebed at Edwards Air Force Base.

From the International Space Station, NASA astronaut Scott Kelly (stationcdrkelly on Instagram) took this photograph and posted it to social media on April 6, 2015. Kelly wrote, "Australia. You are very beautiful. Thank you for being there to brighten our day. #YearInSpace" Kelly and Russian Federal Space Agency (Roscosmos) cosmonaut Mikhail Kornienko began their one-year mission aboard the space station on March 27. Most expeditions to the space station last four to six months. By doubling the length of this mission, researchers hope to better understand how the human body reacts and adapts to long-duration spaceflight. Image Credit: NASA (More at NASA Picture of The Day)
Searching for Water in the Solar System and Beyond
As NASA missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links many seemingly unrelated worlds in surprising ways. Perhaps the most surprising water worlds are the five icy moons of Jupiter and Saturn that show strong evidence of oceans beneath their surfaces: Ganymede, Europa and Callisto at Jupiter, and Enceladus and Titan at Saturn. Scientists using NASA's Hubble Space Telescope recently provided powerful evidence that Ganymede has a saltwater, sub-surface ocean, likely sandwiched between two layers of ice. In this artist’s concept, the moon Ganymede orbits the giant planet Jupiter. The Hubble Space Telescope observed aurorae on the moon generated by Ganymede’s magnetic fields. A saline ocean under the moon’s icy crust best explains shifting in the auroral belts measured by Hubble.

Sea Ice Off East Antarctica's Princess Astrid Coast
On April 5, 2015, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image of sea ice off the coast of East Antarctica’s Princess Astrid Coast. White areas close to the continent are sea ice, while white areas in the northeast corner of the image are clouds. One way to better distinguish ice from clouds is with false-color imagery. In the false-color view of the scene here, ice is blue and clouds are white. The image was acquired after Antarctic sea ice had passed its annual minimum extent (reached on Feb. 20, 2015), and had resumed expansion toward its maximum extent (usually reached in September).

On April 9, 1959, NASA's first administrator, Dr. Keith Glennan, announced the names of the agency's first group of astronauts at a news conference in Washington, D.C. Now known as the "Original Seven," they included three Naval aviators, M. Scott Carpenter, Walter M. Schirra Jr., and Alan B. Shepard Jr.; three Air Force pilots, L. Gordon Cooper Jr., Virgil I. (Gus) Grissom, and Donald K. (Deke) Slayton; along with Marine Corps aviator John H. Glenn Jr. This group photo of the original Mercury astronauts was taken in June 1963 at the Manned Spacecraft Center (MSC), now Johnson Space Center, in Houston, Texas. The astronauts are, left-to-right: Cooper, Schirra, Shepard, Grissom, Glenn, Slayton and Carpenter. Project Mercury became NASA's first major undertaking. The objectives of the program were to place a human-rated spacecraft into orbit around Earth, observe the astronaut's performance in such conditions and safely recover the astronaut and the spacecraft. The Mercury flights proved that humans could live and work in space, and paved the way for the Gemini and Apollo programs as well as for all further human spaceflight.

This image of a circular depression on the surface of Mars was acquired on Jan. 5, 2015 by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter (MRO). The spacecraft has been orbiting Mars since March 2006 and completed its 40,000th orbit around Mars on Feb. 7, 2015. The target of this observation is a circular depression in a dark-toned unit associated with a field of cones to the northeast. At the scale of an image taken by MRO's Context Camera, which provides wide area views to provide context for high-resolution analysis, the depression appears to expose layers especially on the sides or walls, which are overlain by dark sands presumably associated with the dark-toned unit. The HiRISE camera's resolution, which is far higher than that of the Context Camera and its larger footprint, can help identify possible layers. HiRISE is one of six instruments on the Mars Reconnaissance Orbiter. The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colo. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington.

Apollo 13, NASA's third crewed mission to the moon, launched on April 11, 1970. Two days later, on April 13, while the mission was en route to the moon, a fault in the electrical system of one of the Service Module's oxygen tanks produced an explosion that caused both oxygen tanks to fail and also led to a loss of electrical power. The Command Module remained functional on its own batteries and oxygen tank, but these were usable only during the last hours of the mission. The crew shut down the Command Module and used the Lunar Module as a "lifeboat" during the return trip to Earth. Despite great hardship caused by limited power, loss of cabin heat, and a shortage of potable water, the crew returned to Earth, and the mission was termed a "successful failure." This photograph of the Mission Operations Control Room in the Mission Control Center at the Manned Spacecraft Center (now Johnson Space Center), Houston, was taken on April 13, 1970, during the fourth television transmission from the Apollo 13 mission. Eugene F. Kranz (foreground, back to camera), one of four Apollo 13 flight directors, views the large screen at front as astronaut Fred W. Haise Jr., Lunar Module pilot, is seen on the screen.

Expedition 43 Flight Engineer Samantha Cristoforetti of the European Space Agency (ESA) photographed the giant solar arrays on the International Space Station on Feb. 12, 2015. The space station's solar arrays contain a total of 262,400 solar cells and cover an area of about 27,000 square feet (2,500 square meters) -- more than half the area of a football field. A solar array's wingspan of 240 feet (73 meters) is longer than a Boeing 777's wingspan, which is 212 feet (65 meters). Altogether, the four sets of arrays can generate 84 to 120 kilowatts of electricity -- enough to provide power to more than 40 homes. The solar arrays produce more power than the station needs at one time for station systems and experiments. When the station is in sunlight, about 60 percent of the electricity that the solar arrays generate is used to charge the station's batteries. At times, some or all of the solar arrays are in the shadow of Earth or the shadow of part of the station. This means that those arrays are not collecting sunlight. The batteries power the station when it is not in the sun. Image Credit: ESA/NASA (More at NASA Picture of The Day)
SpaceX Launches NASA Cargo and Research To International Space Station
A SpaceX Falcon 9 rocket lifts off from Space Launch Complex 40 at Cape Canaveral Air Force Station carrying the Dragon resupply spacecraft on the sixth commercial resupply services mission to the International Space Station. Liftoff was at 4:10 p.m. EDT, Tuesday, April 14. Research that will help prepare NASA astronauts and robotic explorers for future missions to Mars is among the two tons of cargo on its way to the International Space Station aboard Dragon. The mission is the company's sixth cargo delivery flight to the station through NASA’s Commercial Resupply Services contract. Dragon's cargo will support approximately 40 of the more than 250 science and research investigations that will be performed during Expeditions 43 and 44, including numerous human research investigations for NASA astronaut Scott Kelly's one-year mission in space.

Multi-Utility Technology Testbed Aircraft On the Runway
The X-56A Multi-Utility Technology Testbed (MUTT) is greeted on an Edwards Air Force Base runway by a U.S. Air Force Research Laboratory (AFRL) team member. NASA’s Armstrong Flight Research Center and the AFRL, along with participants from Langley Research Center and Glenn Research Center, and support from Lockheed Martin, are using the second X-56A (dubbed “Buckeye”) to check out aircraft systems, evaluate handling qualities, characterize and expand the airplane’s performance envelope, and verify pre-flight predictions regarding aircraft behavior. The 20-minute flight marked the beginning of a research effort designed to yield significant advances in aeroservoelastic technology using a low-cost, modular, remotely piloted aerial vehicle.

In this Chandra image of ngc6388, researchers have found evidence that a white dwarf star may have ripped apart a planet as it came too close. When a star reaches its white dwarf stage, nearly all of the material from the star is packed inside a radius one hundredth that of the original star. The destruction of a planet may sound like the stuff of science fiction, but a team of astronomers has found evidence that this may have happened in an ancient cluster of stars at the edge of the Milky Way galaxy. Using several telescopes, including NASA’s Chandra X-ray Observatory, researchers have found evidence that a white dwarf star – the dense core of a star like the Sun that has run out of nuclear fuel – may have ripped apart a planet as it came too close.

Measuring Clouds and Aerosols From the Space Station
Clouds can be observed from the International Space Station moving across Earth’s surface, as in this image of New Zealand taken by Expedition 42 Flight Engineer Samantha Cristoforetti. Other tiny solid and liquid particles called aerosols are also being transported around the atmosphere, but these are largely invisible to our eyes. To investigate the layers and composition of clouds and tiny airborne particles like dust, smoke and other atmospheric aerosols, scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland have developed an Earth-observing instrument called the Cloud-Aerosol Transport System, or CATS. The CATS instrument, set to launch to the space station aboard the fifth SpaceX commercial resupply flight, will be the second NASA Earth-observing instrument to be mounted on the exterior of the station. CATS will provide data about aerosols at different levels of the atmosphere. The data are expected to improve scientists' ability to track different cloud and aerosol types throughout the atmosphere. These datasets will be used to improve strategic and hazard-warning capabilities of events in near real-time, such as tracking plumes from dust storms, volcanic eruptions, and wildfires. The information could also feed into climate models to help understand the effects of clouds and aerosols on Earth’s energy balance.
