NASA Goddard Delivers Magnetometers for NASA's Next Mission to Mars

Magnetometers built by scientists and engineers at NASA Goddard Space Flight Center in Greenbelt, Md. for NASA's Mars Atmosphere And Volatile EvolutioN (MAVEN) mission have been delivered to the University of California at Berkeley Space Sciences Laboratory for integration into the Particles and Field Package.

"The team worked hard and completed delivery of the magnetometers on schedule," said Jack Connerney, Magnetometer Instrument Lead from NASA Goddard. "We are looking forward to launch, orbit insertion and seeing the data come back."

The pair of flux gate magnetometers measures the magnetic field at the location of the spacecraft. As part of the Particles and Fields Package, the magnetometer sensors are positioned at the outermost ends of the solar panels to keep them as far away as possible from stray magnetic fields generated by the spacecraft. Since the motion of escaping charged particles is governed by the magnetic field, this measurement is important in understanding how the solar wind interacts with the planet’s atmosphere and causes loss to space.

Stars Pop Onto the Scene in New WISE Image

A new, large mosaic from NASA's Wide-Field Infrared Survey Explorer (WISE) showcases a vast stretch of cosmic clouds bubbling with new star birth. The region -- a 1,000-square-degree chunk of our Milky Way galaxy -- is home to numerous star-forming clouds, where massive stars have blown out bubbles in the gas and dust.

"Massive stars sweep up and destroy their natal clouds, but they continuously spark new stars to form along the way," said WISE Mission Scientist Dave Leisawitz of NASA Goddard Space Flight Center, Greenbelt, Md. Leisawitz is co-author of a new paper reporting the results in the Astrophysical Journal. "Occasionally a new, massive star forms, perpetuating the sequence of events and giving rise to the dazzling fireworks display seen in this WISE mosaic."

The WISE space telescope mapped the entire sky two times in infrared light, completing its survey in February of 2011. Astronomers studying how stars form took advantage of WISE's all-encompassing view by studying several star-forming clouds, or nebulae, including 10 pictured in this new view.
