One of four Magnetospheric Multiscale (MMS) spacecraft, in the background, is seen in a cleanroom at the Naval Research Lab’s, Naval Center for Space Technology, Monday, August 4, 2014, in Washington. The Magnetospheric Multiscale, or MMS, mission will study the mystery of how magnetic fields around Earth connect and disconnect, explosively releasing energy via a process known as magnetic reconnection. The four identical spacecraft are scheduled to launch in 2015 from Cape Canaveral and will orbit around Earth in varying formations through the dynamic magnetic system surrounding our planet to provide the first three-dimensional views of the magnetic reconnection process. The goal of the STP Program is to understand the fundamental physical processes of the space environment from the sun to Earth, other planets, and the extremes of the solar system boundary. Photo Credit: (NASA/Bill Ingalls)

The Preliminary Research Aerodynamic Design to Land on Mars, or Prandtl-M, glider flies after a magnetic release mechanism on the Carbon-Z Cub was activated to air launch the aircraft. A team from NASA's Armstrong Flight Research Center in Edwards, California, conducted the successful research flight.

Justin Hall, left, attaches the Preliminary Research Aerodynamic Design to Land on Mars, or Prandtl-M, glider onto the Carbon-Z Cub, which Justin Link steadies. Hall and Link are part of a team from NASA's Armstrong Flight Research Center in Edwards, California, that uses an experimental magnetic release mechanism to air launch the glider.

A Preliminary Research Aerodynamic Design to Land on Mars, or Prandtl-M, glider was air launched Sept. 7 using a magnetic release mechanism mounted on a Carbon-Z Cub. The team, based at NASA's Armstrong Flight Research Center in Edwards, California, includes, from left, Paul Bean, Justin Hall, Red Jensen, Justin Link, and Nathan Allaire.

VANDENBERG AIR FORCE BASE, CALIF. - Orbital Sciences' L-1011 jet aircraft releases the Pegasus rocket carrying the Space Technology 5 spacecraft with its trio of micro-satellites. The Pegasus will launch the trio of satellites in a "string of pearls" sequence on a near-Earth polar elliptical orbit that will take them from approximately 190 miles (300 kilometers) to 2,800 miles (4,500 kilometers) from the planet. The three spacecraft will conduct science validation using measurements of the Earth's magnetic field collected by the miniature boom-mounted magnetometers on each.

The Cassini spacecraft is on view for the media in the Payload Hazardous Servicing Facility (PHSF) at Kennedy Space Center, Florida. The two-story-tall spacecraft, scheduled for launch on an Air Force Titan IV/Centaur launch vehicle on Oct. 6, is destined to arrive at Saturn in July 2004, where it will orbit and study Saturn, its rings, moons and magnetic environment in detail over a four-year period. Cassini carries a scientific probe called Huygens, provided by the European Space Agency. Huygens will be released from the main Cassini spacecraft and parachute through the atmosphere of Saturn's most intriguing moon, Titan, which is thought to chemically resemble a very cold version of Earth's environment before life began. The Cassini mission is managed for NASA by the Jet Propulsion Laboratory, a division of the California Institute of Technology

NASA image release August 6, 2010 On August 1, 2010, almost the entire Earth-facing side of the sun erupted in a tumult of activity. This image from the Solar Dynamics Observatory of the news-making solar event on August 1 shows the C3-class solar flare (white area on upper left), a solar tsunami (wave-like structure, upper right), multiple filaments of magnetism lifting off the stellar surface, large-scale shaking of the solar corona, radio bursts, a coronal mass ejection and more. This multi-wavelength extreme ultraviolet snapshot from the Solar Dynamics Observatory shows the sun's northern hemisphere in mid-eruption. Different colors in the image represent different gas temperatures. Earth's magnetic field is still reverberating from the solar flare impact on August 3, 2010, which sparked aurorae as far south as Wisconsin and Iowa in the United States. Analysts believe a second solar flare is following behind the first flare and could re-energize the fading geomagnetic storm and spark a new round of Northern Lights.
