Mars Reconnaissance Orbiter (MRO): The Next Step in Mars Exploration
This slide presentation reviews the Mars Reconnaissance Orbiter (MRO), and the science strategy that motivates the exploration of Mars. The MRO is one of several missions that are planned to enhance our understanding of the planet. Included in this presentation is a review of the schedule for the MRO, the science objectives of the mission, the payloads that ae planned for MRO, and the hoped for science that will be attained from them. A review of the mission, from launch to the primary science relay is reviewed and an overview of the orbiter is shown. The presentation details the payloads, and the expected data from the instruments.
Residual Circulation inthe Stratosphere and Lower Mesosphere as Diagnosed from Microwave Limb Sounder Data
Results for the residual circulation in the stratosphere and lower mesosphere between September, 1991, and February, 1994, are presented.
Observations of Mars using Hubble Space Telescope
The lack of a continuous record of Martian meteorology or of volatile cycles on Mars for extended periods of several Martian years seriously hinders efforts to understand the physics of the Martian atmosphere and surface system. The spacecraft observations are limited to only a few isolated time periods, and the Earth based record is limited by the relatively short periods surrounding oppositions when telescopic observations can yield useful data. To remedy this situation, the authors have embarked on a three year program of Mars observations using the Hubble Space Telescope (HST). Several scientific investigations are being carried out using the images, including: a study of the albedo variations; unit mapping of spectral reflectances; determination of optical depths due to aerosols and condensates; a study of the properties of condensate clouds and hoods; comparison of surface and atmospheric features; observation of size and shape of the polar caps; and investigation of surface atmospheric phenomena.
Hubble Space Telescope observations of Mars
Hubble Space Telescope (HST) afforded the possibility of resolving features as small as 100 km on the Martian surface even when it is at the far point of its orbit. Therefore it is ideally suited for monitoring seasonal changes on the red planet. The objectives research include: the study of Martian dust storms; use of images obtained through different filters to study the spectral reflectance of regions on the Martian surface; use of ultraviolet images and spectra to measure the amount of ozone in the planet's atmosphere as a function of location of the planet; use of images to study changes in the albedo of the Mars surface; and use of Planetary Camera images to study Martian clouds and to measure the opacity of the atmosphere.
