In order to fully understand the role methane (CH₄) plays in the microwave emission spectra of the deep atmospheres of the outer planets, over 280 laboratory measurements of the opacity of ammonia in a methane environment have been made in the 5-20 cm wavelength range. All opacity measurements were made with either 100 or 200 mbars of ammonia and with 1 to 3 bars of added methane in the 330-450K temperature range. A formalism for the absorptivity of ammonia broadened by methane has now been developed and had been applied to the Hanley et al. (Icarus, v. 202, 2009) model for the opacity of ammo

Abstract:

Optical instruments for space missions work in hostile environment, it’s thus necessary to accurately study the effects of ambient parameters variations on the equipment. In particular, optical instruments are very sensitive to ambient conditions, especially temperature. This variable can cause dilatation and misalignment of the optical elements, and can also lead to rise of dangerous stresses in the optics. Their displacements degrade the quality of the sampled images. In this work the optics and mountings of a stereo-camera for the BepiColombo mission are modelled and processed by a thermo

Missions for planetary exploration are unique opportunities to provide very meaningful and high-valuable data about the analysed celestial bodies. These missions can characterize many aspects of them, thanks to the different remote sensing instruments included in their science payload.

Abstract:

abstract: A thorough understanding of Europa's geology through the synergy of science and technology, by combining geologic mapping with autonomous onboard processing methods, enhances the science potential of future outer solar system missions. Mapping outlines the current state of knowledge of Europa's surface and near sub-surface, indicates the prevalence of distinctive geologic features, and enables a uniform perspective of formation mechanisms responsible for generating those features. I have produced a global geologic map of Europa at 1:15 million scale and appraised formation scenarios

Introduction. The PhD work has been performed at Institute of Astrophysics and Space Planetology (IAPS-INAF) in the framework of the two projects VISTA (Volatile In-Situ Thermogravimeter Analyser) and CAM (Contamination Assessment Microbalance), funded by Italian Space Agency and European Space Agency, respectively, both aiming at developing a microbalance sensor for space mission applications, i.e. to study the minor bodies of Solar System (i.e., ESA-M5 Missions Call, MarcoPolo-M5, Akon, JEM and Castalia) by measuring in-situ volatiles material of scientific interest (VISTA project) and to as

Abstract:

abstract: Jupiter’s moon Europa is an active target of research because of its unique geology and its potential for habitability. Europa’s icy chaos disrupts and transforms the previous terrain, suggesting melting is involved. Chaos occurs alongside several types of endogenic surface features. These microfeatures are under <100 km2 in area and include uplifts and domes, pits, spots, and hybrid features. The distribution of microfeatures is known in the ~10% of the Europa’s surface that are covered by the regional mosaics (“RegMaps”). The efforts to connect microfeature formation to any kind of

The rover will incorporate a drill that is capable of extracting cores from depths of up to 2 m, a Sample Preparation and Distribution System (SPDS) that will crush the core into small grains and a suite of analytical instruments. A key component of the analytical suite will be the Raman Laser Spectrometer (RLS) that will be used to probe the molecular and mineralogical composition of the samples. In

abstract: There are more than 20 active missions exploring planets and small bodies beyond Earth in our solar system today. Many more have completed their journeys or will soon begin. Each spacecraft has a suite of instruments and sensors that provide a treasure trove of data that scientists use to advance our understanding of the past, present, and future of the solar system and universe. As more missions come online and the volume of data increases, it becomes more difficult for scientists to analyze these complex data at the desired pace. There is a need for systems that can rapidly and int

Abstract:

Multiple gravity assist (MGA) spacecraft trajectories can be difficult to find, an intractable problem to solve completely. However, these trajectories have enormous benefits for missions to challenging destinations such as outer planets and primitive bodies. Techniques are presented to aid in solving this problem with a global search tool and additional investigation into one particular proximity operations option is discussed. Explore is a global grid-search MGA trajectory pathsolving tool. An efficient sequential tree search eliminates v∞ discontinuities and prunes trajectories. Performance

Abstract:

Aerocapture offers a near propellantless and quick method of orbit insertion at atmosphere bearing planetary destinations. Compared to conventional propulsive insertion, the primary advantage of using aerocapture is the savings in propellant mass which could be used to accommodate more useful payload. To protect the spacecraft from the aerodynamic heating during the maneuver, the spacecraft must be enclosed in a protective aeroshell or deployable drag device which also provides aerodynamic control authority to target the desired conditions at atmospheric exit. For inner planets such as

Abstract:

In this thesis work I have been concerned with modeling the magnetic eld of planet Mercury. With this goal in mind, I tested a new method for modeling the time dependent magnetic eld of a planet, the Time Variable Equivalent Source Dipole method. I showed that in the case that applies to Mercury, namely a concentration of observations over the northern hemisphere, this method gives better results than the standard Spherical Harmonic method. The main conclusion of this thesis is that, assuming that the secular variation of Mercury is around one tenth of its main eld, in amplitude, the
