The CONSERT operations planning process for the Rosetta mission
Altobelli, Nicolas; Vallat, Claire; Hubault, Armelle +28 more
The COmet Nucleus Sounding Experiment by Radio wave Transmission (CONSERT / Rosetta) has been designed to sound the interior of the comet 67P/Churyumov-Gerasimenko. This instrument consists of two parts: one onboard Rosetta and the other one onboard Philae. A good CONSERT science measurement sequence requires joint operations of both spacecrafts i…
The Philae Lander: Science planning and operations
Bibring, Jean-Pierre; Jurado, Eric; Ulamec, Stephan +13 more
Rosetta is an ambitious mission launched in March 2004 to study comet 67P/Churyumov-Gerasimenko. It is composed of a space probe (Rosetta) and the Philae Lander. The mission is a series of premieres: among others, first probe to escort a comet, first time a landing site is selected with short turnaround time, first time a lander has landed on a co…
Data processing and visualisation in the Rosetta Science Ground Segment
Geiger, Bernhard
Rosetta is the first space mission to rendezvous with a comet. The spacecraft encountered its target 67P/Churyumov-Gerasimenko in 2014 and currently escorts the comet through a complete activity cycle during perihelion passage. The Rosetta Science Ground Segment (RSGS) is in charge of planning and coordinating the observations carried out by the s…
Rosetta-Philae RF link, challenging communications from a comet
Dudal, Clément; Loisel, Céline
The Rosetta spacecraft reached the vicinity of the comet 67P/Churyumov-Gerasimenko in 2014 and released the lander Philae for an in-situ analysis through 10 scientific instruments. The analysis of the lander RF link telemetry reveals major information on the lander orientation and its near environment during the 50-h mission on the comet. The Phil…
A new terminal guidance sensor system for asteroid intercept or rendezvous missions
Lyzhoft, Joshua; Basart, John; Wie, Bong
This paper presents the initial conceptual study results of a new terminal guidance sensor system for asteroid intercept or rendezvous missions, which explores the use of visual, infrared, and radar devices. As was demonstrated by NASA's Deep Impact mission, visual cameras can be effectively utilized for hypervelocity intercept terminal guidance f…
Ptolemy operations at the surface of a comet, from planning to reality
Andrews, D. J.; Sheridan, S.; Wright, I. P. +3 more
Ptolemy is a Gas Chromatograph-Isotope Ratio-Mass Spectrometer (GC-IR-MS) aboard the Philae lander element of the Rosetta mission to comet 67P/Churyumov-Gerasimenko. Developed to determine the chemical and stable light isotopic composition of cometary material, Ptolemy was conceived as a highly flexible instrument able to accommodate changes in op…
Cosmic ray dose monitoring using RadFET sensors of the Rosetta instruments SESAME and COSIMA
Fischer, Henning; Koch, Andreas; Seidensticker, Klaus J. +5 more
On its more than 10 years journey to comet 67P/Churyumov-Gerasimenko, Rosetta carried RadFET ionising dose monitors in the central electronics of the orbiter instrument COSIMA and the lander instrument SESAME. The readings of the dosimeters were corrected for the temperature of the devices during measurements. Because the sensitivity of RadFETs de…
Command and data management system (CDMS) of the Philae lander
Schmidt, W.; Balázs, A.; Baksa, A. +9 more
The paper covers the principal requirements, design concepts and implementation of the hardware and software for the central on-board computer (CDMS) of the Philae lander in the context of the ESA Rosetta space mission, including some technical details. The focus is on the implementation of fault tolerance, autonomous operation and operational fle…

Editorial of the special issue - "Rosetta and Philae at comet 67P/Churyumov-Gerasimenko"
Taylor, Matthew G. G. T.; Ulamec, Stephan
Giotto, the first european/ESA - interplanetary space probe had not flown by Halley's comet, yet, when the first plans for the next mission to investigate a comet were being made. back in 1984, Rosetta became part of ESAs horizon 2000 programme, originally envisioned as a comet nucleus sample return mission.
