We present Earth-based imaging and photometry results of Deep Impact target comet 9P/Tempel 1 obtained at in the nights surrounding time spacecraft's impact. These observations establish baseline behavior Tempel prior to impact, including a water vaporization rate 6 × 1027 molecules s-1, thereby enabling us determine effects directly caused by this explosive event. The instantaneous fireball was not detected, but postimpact brightening from ejecta material prominent shows evidence slowly...
Knowing precisely where a spacecraft lands on Mars is important for understanding the regional and local context, setting, offset between inertial cartographic frames. For InSight spacecraft, payload of geophysical environmental sensors also particularly benefits from knowing exactly instruments are located. A ~30 cm/pixel image acquired orbit after landing clearly resolves lander large circular solar panels. This was carefully georeferenced to hierarchically generated coregistered set...
Many discoveries of active surface processes on Mars have been made due to the availability repeat high-resolution images from High Resolution Imaging Science Experiment (HiRISE) onboard Reconnaissance Orbiter. HiRISE stereo are used make digital terrain models (DTMs) and orthorectified (orthoimages). DTMs orthoimage time series crucial for advancing study such as recurring slope lineae, dune migration, gully activity, polar processes. We describe process making DTMs, series, DTM mosaics,...
The Mars Reconnaissance Orbiter has been orbiting since 2006 and acquired >80,000 HiRISE images with sub-meter resolution, contributing to over 2000 peer-reviewed publications, provided the data needed enable safe surface landings in key locations by several rovers or landers. This paper describes changes science planning, processing, analysis tools initial Primary Science Phase 2006–2008. These affect used requested community how they should interpret data. There have a variety of...
The Visual and Infrared Mapping Spectrometer observed Phoebe, Iapetus, Titan Saturn's rings during Cassini's approach orbital insertion. Phoebe's surface contains water ice, CO2, ferrous iron. Iapetus CO2 organic materials. Titan's atmosphere shows methane fluorescence, night-side atmospheric emission that may be CH3D. As determined from cloud motions, the winds at altitude 25–30 km in south polar region of appear to moving a prograde direction velocity ∼1 m s-1. Circular albedo features on...
