Cassini | Titan flyby (965 kilometers) -- T-58: UVIS observes a solar occultation while inbound towards Titan, and then a stellar occultation on the spacecraft's outbound trajectory. RADAR's SAR swath runs along the western edge of Xanadu to study its boundary with Shangri-La. The swath runs parallel to the T-55/56/57 mapping sequence and covers Ontario Lacus. | NASA | |
| Jul-24-2009 15:34 |
Cassini | Titan flyby (955 kilometers) -- T-59: The spacecraft's instruments sample Titan's southern mid-latitudes, with the Cassini Plasma Spectrometer (CAPS) controlling pointing at closest approach. | NASA | |
| Aug-09-2009 14:04 |
Cassini | Titan flyby (970) kilometers -- T-60: RADAR takes a South pole pass. The resulting swath links up with the T-13 flyby swath at the edge of Xanadu. ISS will acquire high-resolution, low-phase-angle imaging of western Senkyo. | NASA | |
| Aug-25-2009 12:52 |
Cassini | Titan flyby (970 kilometers) -- T-61: RADAR gathers a SAR swath over the Huygens landing site. The swath is near-equatorial, covering Dilmun, Adiri and Belet. As the SAR parallels and overlaps the T-8 flyby, this should provide a good stereo opportunity over the Belet sand dunes. T-61 is the only southern equatorial wake observation in the mission, so the Magnetosphere and Plasma Science (MAPS) instruments take advantage of the opportunity. | NASA | |

Mission Status
Jun-05-2009 Characterizing Comet Hartley 2 Although the EPOXI mission's spacecraft is in a period of relative inactivity, the team is still actively working on a variety of questions. One of the key areas of investigation is the characterization of the next target, comet Hartley 2. Several investigations have been carried out to characterize the nuclear size and albedo, the large dust, and the rotation of the nucleus. These investigations have been aimed for the period before the nucleus begins outgassing significantly as it approaches the sun. Observation were taken with the Spitzer Space Telescope in August 2008. The analysis of those data yields a nuclear effective radius of 0.6 km, slightly smaller than, but still comparable to, the size deduced using the European Infrared Space Observatory at the previous apparition. These observations also show that there is a trail of large dust particles released much earlier and still orbiting the sun close to the nucleus. This is a common phenomenon among comets. The next step was an effort to determine the rotational period in order to design the observing sequence for the approach to the comet. A series of observations with the Hubble Space Telescope in late April were somewhat puzzling. Subsequent observations with a variety of ground-based telescopes, particularly with Gemini-South and Gemini-North on the same night, have suggested a rotational period near 2/3 day, but with narrow minima that were not caught in the HST observations. |
