Examining the response of the Martian atmosphere to increases in different portions of the electromagnetic spectrum during solar flares
… 2015 the Mars Atmosphere and Volatile Evolution (MAVEN) mission satellite made measurements of the atmosphere and solar irradiance during a solar flare. These measurements were used by the Flare Irradiance Spectral Model (FISM) to generate solar flux values for 59 wavelength bins describing flare …

Effect of Chemistry on Electrodynamics in the Martian Dynamo Region
… causing perturbations of the magnetic field. The MAVEN mission has shown the importance of ion escape in the Martian atmospheric loss, and previous modeling studies [e.g., Riousset et al., 2014] have shown that electrodynamics in the dynamo region may impact upward transport of ions from this …

Solar activity variations of the ionospheres of Venus and Mars
… in situ observations from Pioneer Venus and MAVEN, I show that the expansion of the neutral atmosphere can also alter the ion composition at both planets. Assessing the observations in a fixed neutral number density frame rather than a fixed altitude frame reveals differences between the …

Vertically Propagating Tides in the Martian Atmosphere
… Mars Atmosphere and Volatile Evolution mission (MAVEN) suggest that tides producing wavenumber-2 and wavenumber-3 structures are strongest in the upper atmosphere in a fixed local time reference frame. However, the energy carried by these tides and the region of deposition has not been well …

Proton Aurora at Mars: Assessing the Characteristics, Variability, and Driving Mechanisms of a Newly Discovered Phenomenon
… the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft. Martian proton aurora are observed in IUVS data as a prominent enhancement in the intensity of the hydrogen Lyman-alpha (Ly-α) emission (121.6 nm) between ~110-150 km altitude.</p> <p>Using altitude-intensity profiles from IUVS …

Non-migrating tides in the Martian thermosphere
… of the upper neutral atmosphere of Mars. MAVEN’s Imaging Ultraviolet Spectrometer (IUVS) observations of the upper atmosphere reveal variations in density with longitude at altitudes of 130 – 200 km, and can be used to identify non-migrating tides. These observations cover higher latitudes …

Enhancing CryptoGuard's Deployability for Continuous Software Security Scanning
The increasing development speed via Agile may introduce overlooked security steps in the process, with an example being the Iowa Caucus application. Verifying the protection of confidential information such as social security numbers requires security at all levels, providing protection through …
