participation is mandatory
08:00 am - 09:00 am Lecture
09:00 am - 11:00 am Practical fire protection exercises outdoors, so please wear weatherproof clothing and sturdy shoes!

Update from 24.09.2021
According to the university' s corona regulations, the event will consider the 3G rule. Therefore, participation is only possible with a corresponding proof - vaccinated, tested or recovered - which must be shown at the entrance to the building. Students who need a test, please do it one day before.

The entrance starts one hour before the event begins. Please be there on time for the start at 8 o'clock.

The following fire drill will take place at the practice area in the Emmy-Noether-Strasse behind the SFG building in groups of no more than 100 people. The group formation will take place in the lecture hall after the presentation. Because the exercise will be outside, please remember to wear weatherproof shoes and clothing.

Detailed information about the current Corona hygiene and safety rules at the University of Bremen can be seen under the following link: https://www.uni-bremen.de/informationen-zur-corona-pandemie/fragen-antworten/informationen-fuer-studierende-und-studienanfaengerinnen

Please check StudIp again shortly before the event for the latest news.

Parts of the exercise will be held as a seminar (dates and time slots upon agreement with the students).

Depending on the pandemic situation, the course will either take place online again or in the Simultaneous Design Laboratory (CEF) at DLR (Robert-Hooke-Str.7, Bremen)

Please be sure not to have any parallel exams during these given dates!

Bei zu vielen Anmeldungen: Studierende aus dem M Space Eng werden bevorzugt, insbesondere aus höheren Semestern

This course is to be offered as a one-time add-on during the current winter semester for those students who are unable to attend 04-M30-CP-SAS-3 Space Systems Engineering/Concurrent Engineering due to capacity limitations. The course is also credited in the module "Satellite Systems" and can only be used as a substitute for 04-M30-CP-SAS-3. Please register here so that the demand can be estimated. The scheduling and further detailed planning depends on the number of interested students. Please note that this course will not include practical exercises in the "Concurrent engineering facility" of DLR.

The course is intended exclusively for students who are currently enrolled in the Master's program "Space Engineering". The presentation of appropriate IDs is required.

Course content:

In this seminar, we shall study foundational, historical and philosophical questions of cosmology. The syllabus comprises topics and concepts such as (A) key elements of the cosmological standard model and anomalies within it; (B) cosmology as a science and how contemporary research benefits from an awareness of its historical development; (C) further epistemological and methodological questions regarding, for instance, the heavy reliance on strong idealisations and extrapolations in cosmology.
Formally, no prerequisite knowledge in either cosmology or philosophy is needed (albeit desirable). Diligent preparation of the weekly required reading, and continuous active participation are obligatory for successfully completing this course (See below for the details regarding the course requirements/Leistungsnachweis).

Learning outcome/learning goals:

• Basic knowledge of cosmology.
• Knowledge of basic relevant notions from the philosophy of the natural sciences (natural law, space, time, infinity, …)
• Basic insights into the aims of scientific inquiry and the generation of scientific knowledge (by means of examples from the history of cosmology)

Preparatory literature:

This project aims at a systematic investigation of ultrahigh vacuum technologies for cold atom instruments. Different tools (ANSYS, Inventor, Python,…) and experimental methods (Helium leak detection, absorption spectroscopy, vibration testing, …) will be used to qualify and develop technologies for vacuum seals and oven technologies as alkali-metal source. It shall answer open questions for vacuum systems of cold atom technologies.

The objectives and your tasks in this project will be:

• Read and understand challenges of ultrahigh vacuum systems
• Understand the Theory behind it
• Make yourself familiar with existing simulation setup for structural/thermal simulations
• Adapt existing lab hardware to fill and test ovens
• Test CF-knife edges on dynamic loads (shaker)
• Design and build an oven prototype
• Test oven prototype under operating conditions
• Write and adapt a software for the oven filling facility

A system that was developed for the exact leveling and positioning
of sensitive satellite parts during the AIV process of the
Eu:CROPIS mission.
This experimental device is now to be developed further and
refined to possibly establish a spin-off product.
The main tasks include:
• Development of power, charging and data interfaces
• Development of the basic leveling functionality
• Development of the additional “kinetic sensory” functionality
• Development of the additional “HD camera” functionality
• Development of the firmware for communication and data
interfaces
• Development of the associated API
• Documentation

Phase 0 design of an expander cycle rocket engine for use in future
RLVs and/or upper stages.
This expander cycle engine should be augmented by an electric
pump and provide deep throttling, multi restart capability and green
propellants (IRSU production would be a plus). It should operate in
the lower tens-of kilonewton range and should rely on electrical
motor components that can be acquired of the shelf (COTS) for
example form the high-powered drone sector.
• Propellant choice and performance calculation
• Cycle design
• Trade studies taking available components into account
• Initial rough CAD model (Solidworks licences will be
provided)
• Overall engine performance modelling and estimation
• Documentation of the project
o
Written, models and CAD
Some previous Master thesis with specific pump design models
and data can be used as basis.

To verify developments in the field of novel, flexible, very lightweight photovoltaic applications for space travel, a facility for accelerated, thermal cycling of photovoltaics in a vacuum is to be designed at the DLR Institute of Space Systems in the Mechanical and Thermal Systems department.

At ZARM a payload for measuring accelerations using cold atoms was already integrated. During this project you will use this hardware to:
- Finalize the integration of the payload, apply minor changes to the setup if required
- Implementation of the control software of the payload
- Develop and implement an image analysis tool
- Design of optics for atom interferometry
- Commissioning of the experiment in order to trap atoms
