Abstract We examine the newly discovered phenomena of sinuous aurora on nightside Mars, using images 130.4 and 135.6 nm oxygen emission measured by Emirates Mars Mission EMUS ultraviolet spectrograph, upstream measurements from MAVEN Express spacecraft. They are detected in ∼3% observations, totaling 73 clear detections. These emissions narrow, elongated (1,000–6,000 km), cross Mars' UV terminator, oriented generally toward anti‐solar point, clustering into north, south, east, west‐oriented...
Abstract We present a case study of plasma and magnetic field observations in the Martian magnetotail using data from Mars Atmosphere Volatile EvolutioN (MAVEN) mission during an orbit when spacecraft was optical shadow, past dusk terminator downstream strongest crustal fields. In this region, we observed multiple rotations (a signature currents) closely associated with energized (up to 100 eV) electron populations. Several transitions between closed draped topologies also occur which are...
Thermal (<1 eV) electron density measurements, derived from the Mars Atmosphere and Volatile Evolution's (MAVEN) Langmuir Probe Waves (LPW) instrument, are analyzed to produce first statistical study of thermal population in Martian magnetotail. Coincident measurements local magnetic field used demonstrate that close Mars, is most likely be observed at a cylindrical distance ~1.1 radii (RM) central tail region during times when flares inward toward tail, compared ~1.3 RM outward away...
