The New Horizons spacecraft was launched on January 19, 2006, and on February 28,
2007, encountered the planet Jupiter.
The spacecraft conducted observations
and got a gravity boost en route to Pluto, which it will encounter in July 2015.
In support of this flyby, two Hubble Space Telescope (HST) General Observer (GO)
proposals were approved and prepared:
10862 (PI John Clarke) and
(PI John Spencer).
Following the failure of the ACS side 2 (backup) electronics on
January 27, 2007, STScI Director Matt Mountain granted 20 orbits of his
discretionary time to the Hubble Heritage Team to conduct additional Jupiter
observations with WFPC2
Working closely with the New Horizons science team to
design complementary observations, the Heritage Team conducted a sequence of
multiwavelength observations over a full Jupiter "day" (~10 hours), to globally
map the Jovian cloud structure at the time of the flyby, and then repeat this
sequence again 3 weeks later. Other observations include a transit of Io (with
an active Tvashtar volcanic plume), and some sequential observations of the
Great Red Spot and Little Red Spot. Some observations were lost as a result of
guide star failures, but the main goals of the program were accomplished.
Heritage Press Release
Each filename indicates that it is an HLSP (h_jupiter), the filter wavelength in
nanometers (F255W, F343N, F410M, F673N, F953N), and the observation date
(YYMMDD) followed by a letter code which indicates membership in an observation
sequence. The filter and observation date/time are also visible when these
images are displayed (in the object title). The observations sequence letter
codes are as follows:
|code|| observation sequence|
|a-g|| Full Jupiter rotation (one 10-hour Jupiter "day")|
|x-z|| Consecutive Great Red Spot observations (about 10 hours apart)|
|j|| Little Red Spot (a.k.a Red Spot Jr.) observations|
|i|| Io transit|
