The science planning process on the Rosetta mission
Altobelli, Nicolas; Choukroun, Mathieu; Vallat, Claire +9 more
The Rosetta mission arrived at comet 67 P/Churyumov-Gerasimenko in Summer 2014, after more than 10 years in space. All previous mission encounters with a comet have provided a snapshot of the cometary activity at a given heliocentric distance. In contrast, Rosetta has escorted the comet nucleus for an extended period (>2 years) at a large range…
The final year of the Rosetta mission
Ferri, Paolo; Accomazzo, Andrea; Hubault, Armelle +6 more
The International Rosetta Mission was launched on 2nd March 2004 on its 10 year journey to rendezvous with comet 67P Churyumov-Gerasimenko. Rosetta performed comet orbit insertion on the 6th of August 2014, after which it characterised the nucleus and orbited it at altitudes as low as a few kilometres. In November 2014 Rosetta delivered the lander…
Rosetta Lander - Philae: Operations on comet 67P/Churyumov-Gerasimenko, analysis of wake-up activities and final state
Mottola, Stefano; Scholten, Frank; Kührt, Ekkehard +19 more
The Lander Philae, part of the ESA Rosetta mission successfully landed on comet 67P/Churyumov- Gerasimenko on November 12th, 2014. After several (unplanned) bounces it performed a First Scientific Sequence (FSS), based on the energy stored in its on board batteries. All ten instruments of the payload aboard Philae have been operated at least once.…
Development of a Marslander with crushable shock absorber by virtual and experimental testing
Reinhardt, B.; Schröder, Silvio; Brauner, C. +2 more
Since the beginning of space exploration, probes have been sent to other planets or moons with the associated challenge of landing on these bodies. For a soft landing several damping methods like landing legs or airbags have been used. A new and potentially less complex and lighter way to reduce the shock loads at touchdown is the use of a crushab…
Southern Meridiani Planum - A candidate landing site for the first crewed mission to Mars
Smith, H.; Hobbs, S. W.; Clarke, J. D. A. +2 more
Astronauts working on the surface of Mars have the capability to explore efficiently, rapidly, and flexibly, allowing them to perform a wide range of field investigations. NASA has begun an open international process to identify and evaluate candidate locations where crews could land, live and work on the martian surface, beginning with the First …
Reconstruction of the flight and attitude of Rosetta's lander Philae
Richter, Ingo; Auster, Hans-Ulrich; Heinisch, Philip +14 more
Since Rosetta's lander Philae touched down on comet 67P/Churyumov-Gerasimenko on November 12, 2014, many tools have been applied to reconstruct Philae's flight path and attitude between separation, the touchdowns, collision and the final landing at Abydos. In addition to images from the cameras onboard both orbiter and lander (;OSIRIS;, ;CIVA; and…
Rosetta Lander - Landing and operations on comet 67P/Churyumov-Gerasimenko
Finke, Felix; Ulamec, Stephan; Biele, Jens +10 more
The Rosetta Lander Philae is part of the ESA Rosetta Mission which reached comet 67P/Churyumov-Gerasimenko after a 10 year cruise in August 2014. Since then, Rosetta has been studying both its nucleus and coma with instruments aboard the Orbiter. On November 12th, 2014 the Lander, Philae, was successfully delivered to the surface of the comet and …
Rosetta lander Philae - Landing performance and touchdown safety assessment
Jurado, Eric; Ulamec, Stephan; Biele, Jens +2 more
This paper describes the simulation and analysis work on Rosetta lander Philae's touchdown dynamics which was done to support its Landing Site Selection Process. The simulation part consists of a numerical multi-body simulation to describe Philae's touchdown dynamics. Suitable performance metrics in conjunction with Monte Carlo trajectory data fro…
Rosetta lander Philae: Flight Dynamics analyses for landing site selection and post-landing operations
Vincent, Jean-Baptiste; Kofman, Wlodek; Herique, Alain +20 more
On the 12th of November 2014, The Rosetta Lander Philae became the first spacecraft to softly land on a comet nucleus. Due to the double failure of the cold gas hold-down thruster and the anchoring harpoons that should have fixed Philae to the surface, it spent approximately two hours bouncing over the comet surface to finally come at rest one km …
GIADA - Grain Impact Analyzer and Dust Accumulator - Onboard Rosetta spacecraft: Extended calibrations
Fulle, M.; Rodriguez, J.; Colangeli, L. +12 more
Despite a long tradition of dust instruments flown on-board space mission, the largest number of these can be considered unique as they used different detection techniques. GIADA (Grain Impact Analyzer and Dust Accumulator), is one of the dust instruments on-board the Rosetta spacecraft and is devoted to measure the dust dynamical parameters in th…
