 the United Launch Alliance Atlas V rocket with NASA's Magnetospheric Multiscale (MMS) spacecraft onboard launches from the Air Force Station Space Launch Complex 41 March 12, 2015 in Cape Canaveral, Florida. NASA's MMS mission will study how magnetic fields around Earth connect and disconnect, explosively releasing energy via a process known as magnetic reconnection. MMS consists of four identical spacecraft that work together to provide the first three-dimensional view of this fundamental process, which occurs throughout the universe.

This image released by NASA December 15,...This image released by NASA December 15, 2014 shows the easily recognized boot of Italy, with Sicily at its toe, spread across this panorama taken October 21 by astronauts aboard the International Space Station(ISS). On a clear night looking east, the pattern of night lights shows populations concentrated mainly along the coastlines, but also in the Po River Valley of northern Italy(L). Some of the brightest clusters of lights are Rome and nearby Naples, with island cities of Cagliari on Sardinia and Catania on Sicilynow well-known as the hometown of European Space Agency astronaut Luca Parmitano. The small, dark, circular patch dangerously close to Catania marks the unpopulated slopes of the active volcano Etna. Hazy lights, as over the Po valley and Rome, probably indicate thin clouds above. The island of Malta appears at the lower right. The airglow line is vivid in this night shot.

Orion is scheduled to launch and make its first flight test later in the morning. The spacecraft will orbit Earth twice, reaching an altitude of approximately 3,600 miles above Earth before landing in the Pacific Ocean. No one will be aboard Orion for this flight test, but the spacecraft is designed to allow us to journey to destinations never before visited by humans, including an asteroid and Mars.

Earth seen from the International Space Station...epa04383191 A handout picture made available by NASA on 04 September 2014 shows a view of Earth taken by NASA astronaut Gregory Reid Wiseman of the US from the International Space Station (ISS) on space, 02 September 2014. The Expedition 40 crew has been busy on the ISS performing health checks and humanoid robot upgrades. A trio of orbital residents is packing up gear as they prepare to return home in less than two weeks. Commander Steve Swanson powered down and stowed Robonaut 2 after wrapping up its mobility upgrades this week. He installed new legs on the humanoid robot including external and internal gear as well as cables. This sets the stage for more upgrades in the fall before Robonaut takes its first steps as an assistant crew member. Robonaut was designed to enhance crew productivity and safety while also aiding people on Earth with physical disabilities.  EPA/NASA/REID WISEMAN  HANDOUT EDITORIAL USE ONLY

Martian dune valley...epa04054024 A handout picture made available by NASA on 04 February 2014 show a view combining several frames taken by the Mast Camera (Mastcam) on NASA's Mars rover Curiosity, looking into a dune valley on Mars, 30 January 2014. The team operating Curiosity has chosen this valley as a likely route toward mid-term and long-term science destinations. The foreground dune, at a location called 'Dingo Gap', is about one meter high in the middle and tapered at south and north ends onto low scarps on either side of the gap. The center of the view is about ten degree south of straight west. The left edge is about 20 degree west of straight south. The right edge is northwest. The largest of the dark rocks on the sand in the right half of the scene are about 60 cm across. The image has been white-balanced to show what the rocks would look like if they were on Earth. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, USA, manages the Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington. The Jet Propulsion Laboratory (JPL) designed and built the project's Curiosity rover. Malin Space Science Systems, San Diego, California, USA, built and operates the rover's Mastcam.

Solar Dynamics Observatory Shows Sun's Rainbow of Wavelengths...epa03995749 An undated handout picture released by NASA on 19 December 2013 shows a still image taken from a NASA movie of the sun based on data from NASA's Solar Dynamics Observatory (SDO), showing the wide range of wavelengths, invisible to the naked eye, that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors. Yellow light of 5,800 Angstroms, for example, generally emanates from material of about 5,700 degree Celsius, which represents the surface of the sun. Extreme ultraviolet light of 94 Angstroms, which is typically colorized in green in SDO images, comes from atoms that are about 6,300,000 degree Celsius and is a good wavelength for looking at solar flares, which can reach such high temperatures. By examining pictures of the sun in a variety of wavelengths, as it is done not only by SDO, but also by NASA's Interface Region Imaging Spectrograph, NASA's Solar Terrestrial Relations Observatory and the European Space Agency/NASA Solar and Heliospheric Observatory; scientists can track how particles and heat move through the sun's atmosphere.
