Rosetta Craft Makes Historic Comet Rendezvous European Space Agency's Comet-Chasing Mission Arrives After 10-Year Journey
NATURE | NEWS Rosetta craft makes historic comet rendezvous European Space Agency's comet-chasing mission arrives after 10-year journey. Elizabeth Gibney 06 August 2014 ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA Comet 67P/Churyumov–Gerasimenko, as seen by Rosetta from a distance of 285 kilometres. No one can deny that it was an epic trip. The European Space Agency's comet-chasing Rosetta spacecraft has arrived at its quarry, after launching more than a decade ago and travelling 6.4 billion kilometres through the Solar System. That makes it the first spacecraft to rendezvous with a comet, and takes the mission a step closer to its next, more ambitious goal of making the first ever soft landing on a comet. Speaking from mission control in Darmstadt, Germany, Matt Taylor, Rosetta project scientist for the European Space Agency (ESA), called the space mission “the sexiest there’s ever been”. Rosetta is now within 100 kilometres of its target, comet 67P/Churyumov–Gerasimenko (or 67P for short), which in July was discovered to be shaped like a rubber duck. After a six-minute thruster burn, at 11:29 a.m. local time on 6 August, ESA scientists confirmed that Rosetta had moved into the same orbit around the Sun as the comet. Rosetta is now moving at a walking pace relative to the motion of 67P — though both are hurtling through space at 15 kilometres per second. Unlike NASA’s Deep Impact and Stardust craft, and ESA’s Giotto mission, which flew by their target comets at high speed, Rosetta will now stay with the comet, taking a ring-side seat as 67P approaches the Sun, and eventually swings around it in August 2015. -

Space Science Reviews manuscript No. (will be inserted by the editor) The Puzzle of the Flyby Anomaly Slava G. Turyshev · Viktor T. Toth Received: date / Accepted: date Abstract Close planetary flybys are frequently employed as a technique to place space- craft on extreme solar system trajectories that would otherwise require much larger booster vehicles or may not even be feasible when relying solely on chemical propulsion. The theo- retical description of the flybys, referred to as gravity assists, is well established. However, there seems to be a lack of understanding of the physical processes occurring during these dynamical events. Radio-metric tracking data received from a number of spacecraft that experienced an Earth gravity assist indicate the presence of an unexpected energy change that happened during the flyby and cannot be explained by the standard methods of mod- ern astrodynamics. This puzzling behavior of several spacecraft has become known as the flyby anomaly. We present the summary of the recent anomalous observations and discuss possible ways to resolve this puzzle. Keywords Flyby anomaly · gravitational experiments · spacecraft navigation. 1 Introduction Significant changes to a spacecraft’s trajectory require a substantial mass of propellant. In particular, placing a spacecraft on a highly elliptical or hyperbolic orbit, such as the orbit required for an encounter with another planet, requires the use of a large booster vehicle, substantially increasing mission costs. An alternative approach is to utilize a gravitational assist from an intermediate planet that can change the direction of the velocity vector. Al- arXiv:0907.4184v1 [gr-qc] 23 Jul 2009 though such an indirect trajectory can increase the duration of the cruise phase of a mission, the technique nevertheless allowed several interplanetary spacecraft to reach their target destinations economically (Anderson 1997; Van Allen 2003). -
The Quest to Understand the Pioneer Anomaly
The quest to understand the Pioneer anomaly I Michael Martin Nieto, Theoretical Division (MS-8285) Los Alamos National Laboratory Los Alarnos, New Mexico 87545 USA E-mail: [email protected] +a l1 l I l uring the 1960's, when the Jet Propulsion Laboratory (JPL) Pioneer 10 was launched on 2 March 1972 local time, aboard D first started thinking about what eventually became the an Atlas/Centaur/TE364-4launch vehicle (see Fig. l).It was the "Grand Tours" of the outer planets (the Voyager missions of the first craft launched into deep space and was the first to reach an 1970's and 1980's),the use of planetary flybys for gravity assists of outer giant planet, Jupiter,on 4 Dec. 1973 [l, 21. Later it was the first spacecraft became of great interest. The concept was to use flybys to leave the "solar system" (past the orbit of Pluto or, should we now of the major planets to both mowthe direction of the spacecraft say, Neptune). The Pioneer project, eventually extending over and also to add to its heliocentric velocity in a manner that was decades, was managed at NASAIAMES Research Center under the unfeasible using only chemical fuels. The first time these ideas were hands of four successive project managers, the legendary Charlie put into practice in deep space was with the Pioneers. Hall, Richard Fimrnel, Fred Wirth, and the current Larry Lasher. While in its Earth-Jupiter cruise, Pioneer 10 was still bound to the solar system. By 9 January 1973 Pjoneer l0 was at a distance of 3.40 AU (Astronomical Units'), beyond the asteroid belt. -
High Precision Modelling of Thermal Perturbations with Application to Pioneer 10 and Rosetta
High precision modelling of thermal perturbations with application to Pioneer 10 and Rosetta Vom Fachbereich Produktionstechnik der UNIVERSITAT¨ BREMEN zur Erlangung des Grades Doktor-Ingenieur genehmigte Dissertation von Dipl.-Ing. Benny Rievers Gutachter: Prof. Dr.-Ing. Hans J. Rath Prof. Dr. rer. nat. Hansj¨org Dittus Fachbereich Produktionstechnik Fachbereich Produktionstechnik Universit¨at Bremen Universit¨at Bremen Tag der m¨undlichen Pr¨ufung: 13. Januar 2012 i Kurzzusammenfassung in Deutscher Sprache Das Hauptthema dieser Doktorarbeit ist die pr¨azise numerische Bestimmung von Thermaldruck (TRP) und Solardruck (SRP) f¨ur Satelliten mit komplexer Geome- trie. F¨ur beide Effekte werden analytische Modelle entwickelt und als generischen numerischen Methoden zur Anwendung auf komplexe Modellgeometrien umgesetzt. Die Analysemethode f¨ur TRP wird zur Untersuchung des Thermaldrucks f¨ur den Pio- neer 10 Satelliten f¨ur den kompletten Zeitraum seiner 30-j¨ahrigen Mission verwendet. Hierf¨ur wird ein komplexes dreidimensionales Finite-Elemente Modell des Satelliten einschließlich detaillierter Materialmodelle sowie dem detailliertem ¨außerem und in- nerem Aufbau entwickelt. Durch die Spezifizierung von gemessenen Temperaturen, der beobachteten Trajektorie sowie detaillierten Modellen f¨ur die W¨armeabgabe der verschiedenen Komponenten, wird eine genaue Verteilung der Temperaturen auf der Oberfl¨ache von Pioneer 10 f¨ur jeden Zeitpunkt der Mission bestimmt. Basierend auf den Ergebnissen der Temperaturberechnung wird der resultierende Thermaldruck mit Hilfe einer Raytracing-Methode unter Ber¨ucksichtigung des Strahlungsaustauschs zwischen den verschiedenen Oberf¨achen sowie der Mehrfachreflexion, berechnet. Der Verlauf des berechneten TRPs wird mit den von der NASA ver¨offentlichten Pioneer 10 Residuen verglichen, und es wird aufgezeigt, dass TRP die so genannte Pioneer Anomalie inner- halb einer Modellierungsgenauigkeit von 11.5 % vollst¨andig erkl¨aren kann.
