Sep 20, 2016 – Latest news about the Martian ionosphere: transferable to Earth

Speaker:   Laila Andersson (LASP)
Date & Time:   Sep 20, 2016 ,  4:00 PM Location: LASP Space Science Building, room N100 (1st floor)
Abstract:  

This talk discuss the first 20 months of ionospheric electron temperature and density measurements from the Mars Atmosphere and Volatile Evolution (MAVEN) mission. Below 200 km the electron temperatures are warmer than expected and there is a strong dawn-dusk asymmetry in the ionosphere suggesting a similar asymmetry in the neutral atmosphere. This dawn-dusk asymmetry is similar… Read more »

Aug 16, 2016 – Interaction of the Solar Wind With Comets – A ROSETTA Perspective

Speaker:   Dr. Karl-Heinz Glaßmeier (Technische Universität Braunschweig, Germany)
Date & Time:   Aug 16, 2016 ,  4:00 PM Location: LASP Space Science Building, room N100 (1st floor)
Abstract:  

Interaction of the Solar Wind With Comets – A ROSETTA Perspective

Sep 27, 2016 – The Trailing Edges of High-Speed Solar-Wind Streams

Speaker:   Mick Denton (Space Science Institute, Boulder and New Mexico Consortium, Los Alamos)
Date & Time:   Sep 27, 2016 ,  4:00 PM Location: LASP Space Science Building, room N100 (1st floor)
Abstract:  

High-speed Solar-wind Streams (HSSs) are features in the solar wind that contain plasma originating from coronal holes (e.g. Burlaga [1974], Gosling et al. [1978], Geiss et al. [1995]).  The speed of the plasma within these regions (‘fast’ solar wind) is typically greater that the speed of the plasma that originated from other regions of the Sun… Read more »

Oct 4, 2016 – The ionosphere of Titan

Speaker:   Frank Crary (LASP)
Date & Time:   Oct 4, 2016 ,  4:00 PM Location: LASP Space Science Building, room N100 (1st floor)
Abstract:  

Titan is the only moon in the solar system with a dense atmosphere. Since 2004, the Cassini spacecraft has made 89 flybys passing through Titan’s ionosphere (<2000 km). This makes Titan’s ionosphere the third most thoroughly explored in the solar system, after only the Earth and Mars. In many respects, Titan’s ionosphere resembles the Earth’s… Read more »

Oct 27, 2016 – Giant Planet Magnetodisks

Speaker:   Nick Achilleos (UCL)
Date & Time:   Oct 27, 2016 ,  10:30 AM Location: LASP Space Science Building, room N100 (1st floor)
Abstract:

Nov 1, 2016 – The May 1967 great storm and radio disruption event: Extreme space weather and extraordinary responses

Speaker:   Delores Knipp (CU)
Date & Time:   Nov 1, 2016 ,  4:00 PM Location: LASP Space Science Building, room N100 (1st floor)
Abstract:  

Although listed as one of the most significant events of the last 80 years, the space weather storm of late May 1967 has been of mostly fading academic interest. The storm made its initial mark with a colossal solar radio burst causing radio interference at frequencies between 0.01 and 9.0 GHz and near-simultaneous disruptions of… Read more »

Nov 8, 2016 – Laboratory simulation of cosmic dust impact detection by antenna instruments

Speaker:   Zoltan Sternovsky (LASP)
Date & Time:   Nov 8, 2016 ,  4:00 PM Location: LASP Space Science Building, room N100 (1st floor)
Abstract:  

Antenna-based detection of dust grains by spacecraft is a valuable mechanism to enhance the science return from existing missions, and conduct serendipitous observations of interplanetary dust by spacecraft not equipped with dedicated dust instruments. In principle, the detection mechanism is simple: dust grains encountering the spacecraft at high relative speeds undergo ionization upon impact and… Read more »

Nov 15, 2016 – Observations of Electromagnetic and Electrostatic Waves at the Reconnecting Dayside Magnetopause by the Magnetospheric Multiscale Mission

Speaker:   Rick Wilder (LASP)
Date & Time:   Nov 15, 2016 ,  4:00 PM Location: LASP Space Science Building, room N100 (1st floor)
Abstract:  

On March 12, 2015, NASA launched the Magnetospheric Multiscale (MMS) satellites to study the phenomenon of magnetic reconnection in the Earth’s magnetosphere, especially on the electron scale. One such electron-scale phenomenon is the role of plasma waves, which can be both a consequence of reconnection, and may also impact the dynamics of the diffusion region…. Read more »
