(617) Patroclus has never been observed in the UV spectral region, which contains important diagnostic features of major Trojan surface constituents inferred from fits to visible-near IR spectra. Previous spectral observations have not been spatially resolved, precluding a direct spectral comparison of the two bodies. We propose to obtain full surface UV reflectance maps of both Patroclus and Menoetius using the STIS G230L mode, to search for characteristic absorption features of silicates, carbons/graphites and NH3, which together make up the major inferred Jupiter Trojan surface constituents, and for signs of ''spectral bluing'' that occurs for space-weathered objects. The Jupiter Trojans are believed to represent the most readily accessible Kuiper Belt material in the solar system, having been scattered from that region to their current orbits following a dynamical instability. A direct spectral comparison of Patroclus and Menoetius, indicating whether the objects share a common origin and evolution, will explore the hypothesis that the system is a rare binary survivor of this scattering. (617) Patroclus is also a target of the upcoming Lucy mission, and constraints on surface composition would represent a valuable input to instrument configuration and observation planning work for the mission. As Lucy will not carry a UV instrument, the proposed observations would remain unique and complementary to the results of the mission. ------------------------------------------------------------------------------------ Observations Description ------------------------ The Patroclus-Menoetius binary system will be observed in six single-orbit visits. The time between visits should correspond to 60 +/- 10 degree orbital longitude intervals, but may span multiple Patroclus-Menoetius orbits. The orbital period of the system is ~103 hours, so the offset between visits should be ~17 +/- 3 hours (+ n*103 hours). The STIS slit should be oriented to allow the spectra of the two asteroids, which will appear in the East-West plane in cycle 25, to be separated. If 15111( 7) - 08-Feb-2019 19:37:54 - [ 2] possible, the observations should take place when Patroclus is within 5.2 AU of Earth to optimise the apparent size, brightness and separation of the asteroids, but the slit angle requirement is the more important constraint. ------------------------------------------------------------------------------------ 15111( 7) - 08-Feb-2019 19:37:54 - [ 3] TARGET LIST Solar System Targets ------------------------------------------------------------------------------------------------------------------------------------ TARGET NUMBER: 1 TARGET NAME: PATROCLUS ------------------------------------------------------------------------------------------------------------------------------------ TARGET DESCRIPTION: ASTEROID Asteroid Patroclus ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 1 TARGET POSITION LEVEL 2 TYPE=ASTEROID, A=5.218499694553197, E=0.1399500456355474, I=22.05269861079197, O=44.36596299545594, W=307.8595259822105, M=325.1954514012491, EQUINOX=J2000, EPOCH=08-JUN-2011:00:00:00, EpochTimeScale=TDB ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 3 WINDOWS ------------------------------------------------------------------------------------------------------------------------------------ DATA COMMENTS V = 15.90 Ephemeris Center: EARTH ------------------------------------------------------------------------------------------------------------------------------------ 15111( 7) - 08-Feb-2019 19:37:54 - [ 4] Visit: 01 Visit Requirements: ORIENT 105D TO 165 D; ORIENT 285D TO 345 D; BEFORE 13-JUN-2018:00:00:00 On Hold Comments: Additional Comments: During Cycle 25, the Patroclus-Menoetius mutual orbit will be oriented approximately in the East-West plane. The STIS slit should be positioned to allow the spectra of the two objects to be separated, ideally as close to 135 degrees or 315 degrees as possible. The timing interval shown here covers the period when Patroclus is within 5.2 AU of the Earth to maximize the size and separation of the objects. The slit orientation is the more important requirement. Subsequent visits should be offset to obtain observations at 60 degree +/- 10 degree orbital longitude intervals but the visits do not need to occur in a single orbital period. The orbital period is ~103 hours so the interval between visits should be 17 +/- 3 hours (+ n*103 hours if necessary, where n is any integer).
