ABSTRACT
1
Proposal 13670 (STScI Edit Number: 0, Created: Friday, July 25, 2014 8:27:34 PM EST) - Overview
The 2009 impact and recent superbolides on Jupiter caught the world by surprise and cast doubt on impactor flux estimates for the outer solar system.
Enhanced amateur planetary imaging techniques yield both high spatial resolution (enabling the 2009 impact debris field detection) and rapid frame
rates (enabling the 2010/2012 impact flash detections and lightcurve measurements).
We propose a ToO program to image future impacts on Jupiter and Saturn. To remove the possibility of impact cloud non-detections, the program
will be triggered only if an existing impact debris field is seen, an object on a collision course with Jupiter or Saturn is discovered, or an impact light
curve is measured with an estimated total energy large enough to generate an impact cloud in a giant planet atmosphere (10^20 J).
HST provides the only way to image these events in the ultraviolet, providing information on aerosol altitudes and on smaller particles that are less
visible to ground-based infrared observations. High-resolution imaging with proper timing (not achievable from the ground) is required to measure
precisely both the velocity fields of impact sites and the optical spectrum of impact debris. HST observations of past impacts on Jupiter have also
served both as cornerstones of science investigations at other wavelengths and as vehicles for effective public outreach.
Large outer solar system impacts are governed by the same physics as in the terrestrial events that dominate the impact threat to humans. Studying
the behavior of impactors of various sizes and compositions, as they enter the atmosphere at varying angles and speeds, will better quantify terrestrial
impact hazards.
OBSERVING DESCRIPTION
Observe impact site on target after an impact has been predicted or observed. Target may be Jupiter or Saturn.
Quad subarray (2k x 2k) UVIS imaging data will be acquired in quadrants A and D, due to location of important methane-band filters.
An event will trigger 2 visits, with visit #2 following visit #1 by one target planet rotation (i.e., 6 orbits later for Jupiter or 7 orbits later for Saturn).
Because we include visits to cover both Jupiter and Saturn cases, there are 4 visits in the Phase II even though we were awarded only 2 orbits.
Exposure times must be adjusted once the impact is known, to scale with planetary brightness as the target's heliocentric distance changes over time.
Number and ordering of exposures each orbit will also be adjusted based on actual visibility during the scheduled orbits. POS_TARGs will be used to
avoid guide star reacquisition; POS_TARG values cannot be calculated until the impact latitude/longitude are known.

Comments: EXPOSURE TIMES MUST BE REFINED !!
exposure time here is preliminary because target's heliocentric distance at time of observations is not known. once the timing of the impact is known, exposure times must be adjusted to maximize s/n ratio, avoid satura
tion, and optimize observational efficiency.
