Space Missions to Mercury
Novák, Jakub ; Šťastná, Dagmar (oponent) ; Froehling, Kenneth (vedoucí práce)
The aim of this thesis is to get acquainted with the past and present space missions to planet Mercury, in particular, former NASA´s Messenger mission and a present joint mission of ESA and JAXA, BepiColombo. The thesis outlines their objectives and science results; moreover, it focuses on scientific technology of the missions, including comprehensive instrumental payload description and a survey of the construction design of each spacecraft.

An overview of the spacecraft re-entry on Earth
Macejko, Jakub ; Zikmund, Pavel (oponent) ; Daněk, Vladimír (vedoucí práce)
This bachelor’s thesis is a research thesis describing the issue of the spacecraft, space probes, and other space bodies' re-entry on Earth. This thesis is divided into five chapters. In the first four chapters, the reader will learn about the distribution of re-entry methods, types of re-entry trajectories, and thermal issues. In the last and most comprehensive chapter, the reader will learn about the methods of kinetic energy reduction used in the final stages of re-entry

The Juno Mission to Jupiter
Gall, Jiří ; Sedláček, Pavel (oponent) ; Froehling, Kenneth (vedoucí práce)
The semestral thesis focuses on the exploration of the planet Jupiter by the Juno spacecraft. In this paper are outlined missions to Jupiter prior the Juno with the goals they achieved. Then the work focuses solely on the Juno mission, whose goal is to understand the origin and formation of Jupiter. Furthermore, is described mission timeline since launch to the mission deorbit. Following with the description of the spacecraft construction design and the various subsystem, along with the nine instruments implemented for the planet’s investigation. are described and comment preliminary results of the Juno mission.

MR vzpěra pro vibroizolační Stewardovu plošinu pro kosmonautiku
Macháček, Ondřej ; Šindelář, Martin (oponent) ; Mazůrek, Ivan (vedoucí práce)
Práce se zabývá návrhem magnetoreologické vzpěry vibroizolačního adaptéru pro kosmonautiku. Pro její optimalizaci je nutné sestavit několik virtuálních modelů. Dynamický model mechanismu – Stewartovy plošiny, reologický model pro určení tlumicí síly MR tlumiče, model magnetického obvodu pro zaručení požadované intenzity ve štěrbině. Tyto modely spolu s kontrolními, které se zabývají především pevnostními výpočty, pomohou při konstrukčním návrhu. Navrhování pomocí virtuálních modelů, vyžaduje verifikaci a neustálou kontrolu. Jelikož jde o poměrně široké téma zahrnující kromě eliminace vibrací také kinematiku, dynamiku, hydrauliku, pneumatiku a v neposlední řadě i elektrotechniku a magnetismus, je nezbytné komunikovat s odborníky v daných oborech a jejich znalosti a zkušenosti použít při tvorbě, ale také kontrole jednotlivých modelů. Práce probíhá ve spolupráci s Aerospace Division firmy Honeywell (ESA).

Influence of space debris on satellites design
Hláčik, Adam ; Lazar, Václav (oponent) ; Bartoněk, Jaroslav (vedoucí práce)
The bachelor thesis summarizes the space debris problem and its impacts on the uncrewed spacecraft design. The primary goal is to combine theoretical understandings of the space debris topic with the practical implementation of these findings in the "design for debris" strategy. The first chapter of the thesis examines the properties of space. debris. Findings from this chapter must be considered during the mission and spacecraft design phase, alongside other design driving attributes. The practical part demonstrates the "design for debris" approach in a model case study. The design approach is based on the Micro Meteriod and Orbital Debris analysis findings, which characterize the interaction of debris particles with spacecraft during the course of a mission. Alongside characterization of debris population on mission orbit, analysis can detect weak spots of spacecraft design that are vulnerable to debris impact. Risk-reducing modifications based on analysis data and problem understanding can be applied to reduce the possibility of a spacecraft failure. Another analysis iteration can verify the effectiveness of proposed modifications.

Apollo - člověk na Měsíci
Švancara, Marek ; Tumis, Stanislav (vedoucí práce) ; Horčička, Václav (oponent)
Studie analyzuje okolnosti a důvody, které byly příčinou vzniku ambiciózního plánu, jenž umožnil Spojeným státům dopravit člověka na Měsíc a zase jej bezpečně navrátit zpět na Zemi. Tato práce rovněž klade důraz na jednotlivé pilotované expedice, a to i očima přímých účastníků. Součástí studie je kapitola věnovaná výcviku a přípravě astronautů. Práce připomíná i málo známou skutečnost, že mezi lidmi, kteří stanuli na Měsíci, byl také astronaut s československými kořeny Eugene A. Cernan. V samotném závěru studie je i kapitola věnovaná technice, díky níž se program Apollo zařadil mezi největší události 20. století.
