The USGS list 967 craters: from the largest, Mead at Probably due to radar shadowing differences, these are 270 km diameter, to the smallest, unnamed at 1.3 km. easily recognised and avoided during analysis. Initially, research focussed on the larger craters.

Supervisor: Dr. Francesco Topputo, TU Delft/Politecnico di Milano Dr. Ryan Russell, The University of Texas at Austin Thesis committee: Dr. Francesco Topputo, TU Delft/Politecnico di Milano Prof. dr. ir. Pieter N.A.M. Visser, TU Delft ir. Ron Noomen, TU Delft Dr. Angelo Cervone, TU Delft This thesis is confidential and cannot be made public until December 31, 2020. An electronic version of this thesis is available at http://repository.tudelft.nl/. Cover picture adapted from https://steemitimages.com/p/2gs...QbQvi EXECUTIVE SUMMARY Ballistic capture is a relatively novel concept in interplanetary mission design with the potential to make Mars and other targets in the Solar System more accessible. A complete end-to-end interplanetary mission from an Earth-bound orbit to a stable science orbit around Mars (in this case, an areostationary orbit) has been conducted using this concept. Sets of initial conditions leading to ballistic capture are generated for different epochs. The influence of the dynamical model on the capture is also explored briefly. Specific capture trajectories are then selected based on a study of their stabilization into an areostationary orbit. -

The Magellan Spacecraft at Venus by Andrew Fraknoi, Astronomical Society of the Pacific
www.astrosociety.org/uitc No. 18 - Fall 1991 © 1991, Astronomical Society of the Pacific, 390 Ashton Avenue, San Francisco, CA 94112. The Magellan Spacecraft at Venus by Andrew Fraknoi, Astronomical Society of the Pacific "Having finally penetrated below the clouds of Venus, we find its surface to be naked [not hidden], revealing the history of hundreds of millions of years of geological activity. Venus is a geologist's dream planet.'' —Astronomer David Morrison This fall, the brightest star-like object you can see in the eastern skies before dawn isn't a star at all — it's Venus, the second closest planet to the Sun. Because Venus is so similar in diameter and mass to our world, and also has a gaseous atmosphere, it has been called the Earth's "sister planet''. Many years ago, scientists expected its surface, which is perpetually hidden beneath a thick cloud layer, to look like Earth's as well. Earlier this century, some people even imagined that Venus was a hot, humid, swampy world populated by prehistoric creatures! But we now know Venus is very, very different. New radar images of Venus, just returned from NASA's Magellan spacecraft orbiting the planet, have provided astronomers the clearest view ever of its surface, revealing unique geological features, meteor impact craters, and evidence of volcanic eruptions different from any others found in the solar system. This issue of The Universe in the Classroom is devoted to what Magellan is teaching us today about our nearest neighbor, Venus. Where is Venus, and what is it like? Spacecraft exploration of Venus's surface Magellan — a "recycled'' spacecraft How does Magellan take pictures through the clouds? What has Magellan revealed about Venus? How does Venus' surface compare with Earth's? What is the next step in Magellan's mission? If Venus is such an uninviting place, why are we interested in it? Reading List Why is it so hot on Venus? Where is Venus, and what is it like? Venus orbits the Sun in a nearly circular path between Mercury and the Earth, about 3/4 as far from our star as the Earth is. -
Politecnico Di Milano Modeling and Optimization of Aero-Ballistic Capture
POLITECNICO DI MILANO School of Industrial and Information Engineering Master of Science in Space Engineering MODELING AND OPTIMIZATION OF AERO-BALLISTIC CAPTURE Supervisor Prof. Francesco TOPPUTO Candidate Carmine GIORDANO Matr. 836570 ACADEMIC YEAR 2015/2016 ABSTRACT n this thesis a novel paradigm for Mars missions is formulated, modeled and asses- sed. This concept consists of a maneuver that combines two of the most promising Imethods in terms of mass saving: aerocapture and ballistic capture; it is labeled aero-ballistic capture. The idea is reducing the overall cost and mass by exploiting the interaction with the planet atmosphere as well as the complex Sun–Mars gravitational field. The aero-ballistic capture paradigm is first formulated. It is split into a number of phases, each of them is modeled with mathematical means. The problem is then stated by using optimal control theory, and optimal solutions, maximizing the final mass, are sought. These are specialized to four application cases. An assessment of aero-ballistic capture shows their superiority compared to classical injection maneuvers when medium-to-high final orbits about Mars are wanted. i SOMMARIO n questa tesi, è formulato, modellato e valutato un nuovo paradigma per missioni verso Marte. Questi consiste in una manovra che combina due dei metodi più Ipromettenti in termini di riduzione della massa, l’aerocattura e la cattura balistica, ed è definito cattura aero-balistica. L’idea è di ridurre il costo totale e la massa andando a sfruttare sia l’interazione con l’atmosfera sia il complesso campo gravitazionale creato dal Sole e da Marte. Come primo punto, è formulato il paradigma della cattura aero- balistica, dividendo la manovra in una serie di fasi, ognuna modellata matematicamente. -

Point of contact: [email protected] Introduction: On Earth, economically viable mineralization associated With large impact craters can often be identified by its magnetic signatures [1,2]. The magnetic field from these features decays With the inverse of distance, such that identification requires low altitude measurements. On the Moon, many of the large Nectarian-aged impact features have prominent magnetic features associated With their central peak regions [3]. It is possible that the signatures of economic mineralization could be iden- tified at the Moon With low altitude (<20 km) in situ magnetic field measurements. Tethered Architecture: However, low altitude lunar orbits (<50 km) tend to be unstable, such that without regular orbit maintenance maneuvers they last only a feW Weeks before impacting the Moon [4]. A mission surveying lunar magnetic fields Would require at least a feW months, if not more than a year.

Meteoros y sus diferentes manifestaciones. Imagen 1: Las diferencias entre meteoroide, meteoro y meteorito. Imagen https://www.researchgate.net/ Los ‘bólidos’ son meteoros que parecen más brillantes de lo normal. Una gran mayoría del material que orbita en el espacio exterior son pequeños trozos de piedra, hielo o metal de tamaño submilimétrico, o una combinación de estos materiales. Estos se conocen como micrometeoroides o simplemente polvo espacial. Estos diminutos fragmentos no pueden producir suficiente luz para ser vistos cuando se encuentran con la atmósfera y, sin embargo, contribuyen con muchas toneladas de material al peso de la Tierra cada año. A medida que el tamaño de estos objetos se acerca a un milímetro, comienzan a producir suficiente luz para ser vistos al entrar a la atmósfera superior como meteoros ordinarios. Debido a la velocidad a la que golpean la atmósfera de la Tierra, los fragmentos de más de 1 milímetro tienen la capacidad de producir un destello brillante cuando atraviesan los cielos. Estos meteoritos brillantes son lo que llamamos bolas de fuego y, a menudo, infunden temor y asombro a quienes los presencian. Las bolas de fuego ocurren todos los días en toda la Tierra. Sin embargo, para el individuo, son un espectáculo raro que se presencia muy pocas veces en la vida. Debe recordarse que las bolas de fuego también ocurren durante el día o en una noche nublada. También ocurren sobre el océano o sobre porciones de tierra deshabitadas.
