The dusk dawn orbit of the Odin spacecraft provides sunlit coverage of the equatorial region throughout the year.
Advantages and drawbacks of each mission concept are assessed, and a comparison in terms of high-latitude coverage and distance, spacecraft mass, payload and lifetime is presented.
Novel ground-based wide-area sensor networks, such as the LOFAR Outrigger In Scandinavia (LOIS, LOFAR: Low Frequency Array) radar facility, comprising wide band, and vector-sensing radio receivers with full three-dimensional polarization coverage, and multi-spacecraft plasma diagnostics should help solve outstanding problems of space physics and describe long-term environmental changes.
Throughout the day on Wednesday, the government-run television network, CCTV, provided exhaustive coverage of the orbiting spacecraft, a marked contrast to the scant information provided before the launching.
The ions (Ei≥50 keV) and electrons (Ee≥30 keV) are detected by five separate solid-state detector telescopes, oriented to provide essentially complete pitch angle coverage from the spinning spacecraft.
In the case of GRAIL KBRR data, our interest is especially in areas where the altitude of the spacecraft was low and/or where the coverage was dense.
However, there is a very large difference near dusk, but this is most likely due to the very limited coverage of the Polar spacecraft in this sector.
The sensor covers a 2π-radian disklike field of view with 16 detectors, and the full solid angle coverage is achieved through the spacecraft's spin motion.
Additional high-resolution spectral data coverage obtained by the MRO spacecraft in the future will improve mineralogical characterization of the mounds and further discussions of possible diagenetic processes and/or hydrothermal alteration.
Direct tests of the intrusion of new plasma to the onset region can be performed using spacecraft (Xing et al. 2010), though sparse coverage of the plasma sheet by spacecraft that makes opportunities for such a test is very limited.
