@nasa : Space Station Sensor to Capture 'Striking' Lightning Data - Our researchers developed the Lightning Imaging Sensor (LIS) aboard the TRMM satellite, which detects and locates lightning over the tropical region of the globe. The team that created this hardware in the mid-1990s built a spare, which is scheduled to launch to the International Space Station in February 2016 in order to take advantage of the orbiting laboratory’s high inclination. LIS measures the amount, rate and radiant energy of global lightning, providing storm-scale resolution, millisecond timing, and high, uniform-detection efficiency -- and it does this without land-ocean bias. One of the crew members aboard the International Space Station photographed this night view of storm clouds over Southern California. Early morning lightning can be seen as a white blotch just to the right of center. The yellow colored area, beneath the grey clouds, which almost shines because of night lights, is part of the highly populated area of Los Angeles and San Diego.

Direct Measurement of Distant Black Hole's Spin - Multiple images of a distant quasar are visible in this combined view from NASA’s Chandra X-ray Observatory and the Hubble Space Telescope. The Chandra data were used to directly measure the spin of the supermassive black hole powering this quasar. Gravitational lensing by an intervening elliptical galaxy has created four different images of the quasar, shown by the Chandra data in pink. Such lensing, first predicted by Einstein, offers a rare opportunity to study regions close to the black hole in distant quasars, by acting as a natural telescope and magnifying the light from these sources. The Hubble data in red, green and blue shows the elliptical galaxy in the middle of the image, along with other galaxies in the field. The quasar is known as RX J1131-1231, located about 6 billion light years from Earth. The authors of the new study found that the X-rays are coming from a region in the disk located only about three times the radius of the event horizon, the point of no return for infalling matter. This implies that the black hole must be spinning extremely rapidly to allow a disk to survive at such a small radius. The discovery that the black hole in RX J1131 is spinning at over half the speed of light suggests that this black hole has grown via mergers, rather than pulling material in from different directions.

Our Hubble Space Telescope finds life is too fast, too furious for this runaway galaxy. The spiral galaxy ESO 137-001 looks like a dandelion caught in a breeze. The galaxy is zooming toward the upper right of this image, in between other galaxies in the Norma cluster located over 200 million light-years away. The road is harsh: intergalactic gas in the Norma cluster is sparse, but so hot at 180 million degrees Fahrenheit that it glows in X-rays. The spiral plows through the seething intra-cluster gas so rapidly – at nearly 4.5 million miles per hour — that much of its own gas is caught and torn away. Astronomers call this "ram pressure stripping." The galaxy’s stars remain intact due to the binding force of their gravity.

Into an Aurora! On March 3, 2014, at 6:09 a.m. EST, a NASA-funded sounding rocket launched straight into an aurora over Venetie, Alaska. The Ground-to-Rocket Electrodynamics – Electron Correlative Experiment (GREECE) sounding rocket mission, which launched from Poker Flat Research Range in Poker Flat, Alaska, will study classic curls in the aurora in the night sky. The GREECE mission seeks to understand what combination of events sets up these auroral curls as they're called, in the charged, heated gas – or plasma – where aurorae form. This is a piece of information, which in turn, helps paint a picture of the sun-Earth connection and how energy and particles from the sun interact with Earth's own magnetic system, the magnetosphere.

Our aeronautics research focuses on substantially reducing fuel consumption, emissions and noise -- to make the Next Generation Air Transportation System, or NextGen, a reality. We also are tackling emerging global challenges facing aviation in the coming decades. Here NASA Dryden Flight Loads engineer William Lokos monitors a wing loading test of NASA G-III 804 during recent testing in support of the Adaptive Compliant Trailing Edge, or ACTE, project.

Earth Science, Weather and Climate Change - The budget sustains NASA’s vital role in helping us understand the Earth’s systems and climate and the dynamics between our planet and the sun. This year, NASA and its international partners will launch an unprecedented five Earth science missions to find answers to critical challenges facing our planet today and in the future, including climate change, sea level rise, freshwater resources and extreme weather events. Here, NASA's Orbiting Carbon Observatory spacecraft is moved into a thermal vacuum chamber at Orbital Sciences Corporation's Satellite Manufacturing Facility in Gilbert, Ariz., for environmental tests.
