Particles and Fields Package Integrated on Upcoming Mars-Bound Spacecraft

15.03.2013
The six science instruments that comprise the Particles and Fields Package that will characterize the solar wind and ionosphere of Mars have been integrated aboard NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft. The spacecraft is on track for launch later this year.

The Solar Wind Electron Analyzer (SWEA) was the last of the six instruments to be delivered, and was integrated late last week at Lockheed Martin in Littleton, Colo. SWEA measures the properties of electrons at Mars, one electron at a time, and can process up to one million events per second.

The other instruments in the package had been delivered earlier. In addition to the SWEA instrument, the package includes the Solar Wind Ion Analyzer (SWIA), Suprathermal and Thermal Ion Composition (STATIC), Solar Energetic Particle (SEP), Langmuir Probe and Waves (LPW), Magnetometer (MAG), and a data-processing unit.

"The Particles and Fields Package is designed to study the solar wind interaction with Mars and the structure and dynamics of Mars' ionosphere, including the influence of Mars' strongly magnetized crust," said David L. Mitchell, SWEA instrument lead and coordinator for the full package, from the University of California, Berkeley/Space Sciences Laboratory (SSL). "The package measures solar ultraviolet flux, solar wind properties, and energetic particles produced in solar storms to help us understand how the Sun influences the upper atmosphere and drives atmospheric escape."

The package was built by the University of California, Berkeley/Space Sciences Laboratory (SSL) with support from the University of Colorado Boulder/Laboratory for Atmospheric and Space Physics (CU/LASP) and NASA's Goddard Space Flight Center.

"The final components of the science payload are coming together, so we’re getting closer to being ready for launch," said Bruce Jakosky, MAVEN principal investigator from CU/LASP. "I look forward to the exciting and diverse science results that the Particles and Fields Package instruments will provide.”

The MAVEN spacecraft will carry two other instrument suites. The Remote Sensing Package, built by CU/LASP, will determine global characteristics of the upper atmosphere and ionosphere. The Neutral Gas and Ion Mass Spectrometer, provided by NASA Goddard, will measure the composition and isotopes of neutral ions.

“We’re in the home stretch now of completing the assembly and test of the spacecraft. With the full complement of Particles and Fields Package instruments now onboard the spacecraft, we are in a very good position for delivering the spacecraft to the launch site on schedule in August”, said David F. Mitchell, MAVEN project manager from NASA’s Goddard Space Flight Center in Greenbelt, Md.

MAVEN is scheduled for launch in November, 2013. It is the first spacecraft devoted to exploring and better understanding the Martian upper atmosphere. MAVEN will investigate the role that loss of Mars' atmosphere to space played in determining the history of water on the surface.

MAVEN’s principal investigator is based at the University of Colorado at Boulder's Laboratory for Atmospheric and Space Physics. The university provides science instruments and leads science operations, and Education and Public Outreach. NASA's Goddard Space Flight Center manages the project and provides two of the science instruments for the mission. Lockheed Martin of Littleton, Colo., built the spacecraft and is responsible for mission operations. The University of California at Berkeley Space Sciences Laboratory provides science instruments for the mission. NASA’s Jet Propulsion Laboratory, Pasadena, Calif., provides navigation support, the Deep Space Network, and the Electra telecommunications relay hardware and operations. Goddard Release: 13-014

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
